  As described above, proximity wireless communication is a very useful technique, and the utility of the communication device is improved by using it in the communication device. However, when the information processing terminal is brought close to the communication device in order to establish close proximity wireless communication, the operation button or the like may be erroneously operated by an input medium such as a user's finger holding the information processing device. In particular, when a touch sensor is employed as the operation button, a user operation may be performed just by approaching the input medium, and therefore, an operation error is likely to occur.

  The present invention has been made in view of such circumstances. In a communication device having an operation button and capable of performing close proximity wireless communication with an information processing terminal, the information processing terminal is a communication device. Provided is a technique for suppressing an erroneous operation of an operation button when it is approached.

  In order to solve the above-described problem, a communication device according to the present invention includes a proximity wireless communication unit that performs proximity wireless communication with an information processing terminal that exists within a communication range in which proximity wireless communication is possible, and a reception unit that receives a user operation. And a stop means for stopping the communication function of the close proximity wireless communication means, comprising a control device for controlling the operation of the communication apparatus according to the user operation received by the receiving means. The control device includes a setting unit that sets a reaction time, which is a time from when the receiving unit receives the user operation to when processing according to the user operation starts, and the setting unit stops the stop A first reaction time, which is the reaction time when the communication function by the proximity wireless communication means is not stopped by the means, Communication function by Shin means and setting the time longer than the second reaction time is the reaction time if it is stopped.

The reaction time when the communication function by the close proximity wireless communication means is stopped by the stop means is the second time And setting to be longer than between latency time.

In the communication device according to the invention according to claim 1 and the program according to the invention according to claim 8, the state in which the communication function of the close proximity wireless communication means is stopped, that is, the close proximity wireless communication is invalid, Switching is possible between a state in which the communication function of the close proximity wireless communication means is not stopped, that is, a state in which close proximity wireless communication is effective. And the 1st reaction time which is the response time of the operation button in the state where proximity wireless communication is effective is made longer than the 2nd reaction time which is the response time of the operation button in the state where proximity wireless communication is invalid. Yes. Thereby, in the state where the proximity wireless communication is valid, using the time until the operation button reacts, that is, the time from when the operation button is operated until the processing according to the button operation is started, It is possible to determine whether the button operation is an operation according to the user's intention. Therefore, according to the communication device and the program described in the present invention, it is possible to suppress erroneous operation of the operation button when the information processing terminal is brought close to the communication device.

In the communication device according to the second aspect of the present invention, in the state where the proximity wireless communication is valid, the proximity wireless communication with the information processing terminal is not performed until the first reaction time elapses after the operation button is operated. If it does not start, it is possible to execute processing by button operation. In other words, when the proximity wireless communication with the information processing terminal does not start at the time of the button operation, the button operation is different from the button operation due to the approach of the information processing terminal to the communication device, and the button according to the user's intention The operation is determined, and processing according to the button operation is executed. As a result, it is possible to appropriately execute processing by button operation according to the user's intention.

Further, in the communication device according to the invention according to claim 3, it is possible to control the operation of the communication device based on the command data from the information terminal, and an operation for changing the operation mode of the communication device.

And when the operation button unrelated to the change of the operation mode of the communication device is operated, the first reaction time elapses after the operation button is operated regardless of the presence or absence of the proximity wireless communication with the information processing terminal. Before, it is possible to execute processing by button operation. As a result, when an operation button unrelated to the change of the operation mode of the communication device is operated, it is possible to execute processing based on the button operation with good response.

In the communication device according to the fourth aspect of the invention, the first reaction time of the operation button for changing the operation mode of the communication device can be set longer than the second reaction time. Thereby, it becomes possible to suppress the change of the operation mode of the communication apparatus due to an erroneous operation, and it is possible to appropriately perform processing using close proximity wireless communication.

In the communication device according to the fifth aspect of the invention, when the communication device has a plurality of operation buttons, all the first reaction times of the plurality of operation buttons are set longer than the second reaction time. It is possible. Thereby, it becomes possible to suppress erroneous operation of the operation button with certainty.

<First Embodiment>
FIG. 1 shows a block diagram of an MFP (abbreviation of Multifunction Peripheral) (an example of a communication apparatus of the present invention) 10 exemplified as the first embodiment according to the present application, and FIG. 2 shows a perspective view of the MFP 10.

An example) 18, a printer 20, a scanner 22, a modem 24, a telephone line connection unit 26, and an NFC (abbreviation of Near Field Communication) I / F (an example of near field communication means of the present invention) 28 are mainly provided. These components can communicate with each other via the input / output port 30.

  The panel 16 includes a display surface that displays various functions of the MFP 10, and the display surface is a pressure-sensitive touch panel. The button input unit 18 includes a touch sensor, detects the approach or contact of the input medium to the button input unit 18, and accepts a button operation by the user.

  The printer 20 is a part that executes printing. The scanner 22 is a part that scans a document and creates scan data. The modem 24 modulates the original data to be transmitted by the facsimile function into a signal that can be transmitted to the telephone line network 32 and transmits the signal via the telephone line connection unit 26, or from the telephone line network 32 via the telephone line connection unit 26. The received signal is received and the original data is demodulated.

  Further, the CPU 12 executes processing according to a control program (an example of the program of the present invention) 50 in the storage unit 14. The control program 50 is a program for suppressing erroneous operations on the button input unit 18. The storage unit 14 is configured by combining a RAM (abbreviation of random access memory), a ROM (abbreviation of read only memory), a flash memory, an HDD (abbreviation of hard disk), a buffer provided in the CPU 12, and the like.

  In addition, the storage unit 14 includes a data storage area 52. The data storage area 52 is an area for storing image data of an image to be displayed on the panel 16, data necessary for executing the control program 50, and the like.

  The NFC I / F 28 can perform the NFC wireless communication 60 with the mobile phone 70 (an example of the information processing terminal of the present invention) based on the international standard of ISO / IEC 21481 or ISO / IEC 18092. Has been. In other words, the MFP 10 can directly perform data communication with the mobile phone 70 when it is ready to perform NFC wireless communication 60.

<Operation of MFP>
As described above, the MFP 10 can perform NFC wireless communication (hereinafter sometimes abbreviated as NFC communication) 60 via the NFC I / F 28, and directly with the mobile phone 70. Data communication is possible. Specifically, the NFC I / F 28 includes an antenna unit 80 that transmits and receives radio waves used for wireless communication 60 with the mobile phone 70. As shown in FIG. 2, a top cover 86 is provided on the upper surface (an example of the surface portion of the present invention) 82 of the housing (an example of the housing of the present invention) of the MFP 10, and the antenna unit 80 is provided on the top cover 86. It is arranged.

  As shown in FIG. 3, the antenna unit 80 is disposed on the right side of the top cover 86, and the panel 16 is disposed on the left side of the top cover 86. Further, on the top cover 86, three operation keys 100, 102, and 104 of the button input unit 18 are disposed between the antenna unit 80 and the panel 16. The operation keys 100, 102, and 104 are capacitance type touch keys, and detect the contact or approach of an input medium such as a finger using a change in capacitance. The button input unit 18 has a plurality of operation keys in addition to the operation keys 100, 102, and 104, and some of the plurality of operation keys are located on both sides of the top cover 86 as shown in FIG. The other operation keys are arranged on the side surface of the casing 82 of the MFP 10. Other operation keys include a capacitive touch key, a pressure-sensitive touch panel, a mechanical key, and the like. The mechanical key is an operation key having a structure for detecting presence / absence of button operation by contact / non-contact of a plurality of contacts.

  When establishing NFC communication between the MFP 10 and the mobile phone 70, the user brings the mobile phone 70 closer to the antenna unit 80. When the distance between the mobile phone 70 and the antenna unit 80 falls within the wireless communication range of the mobile phone 70 due to the approach to the antenna unit 80 of the mobile phone 70, the mobile phone 70 and the antenna unit 80, that is, the MFP 10. NFC communication is established between them. Accordingly, the MFP 10 can perform transmission / reception of data such as a telephone number and an image with the mobile phone 70 using NFC communication.

  Specifically, the MFP 10 is in a state where NFC communication cannot be performed in a normal state, that is, a state where NFC communication is disabled. For this reason, in a state where NFC communication is disabled, even if the user brings the mobile phone 70 close to the antenna unit 80, NFC communication is not established. Further, in a state where NFC communication is disabled, a home screen is displayed on the panel 16 as shown in FIG. That is, the MFP 10 is configured to disable the NFC communication function when displaying the home screen. On the home screen, an NFC communication enabling button 110 is displayed. The NFC communication enable button 110 is a button for setting a state where NFC communication can be performed by a user operation, that is, a state where NFC communication can be established by approaching the antenna unit 80 of the mobile phone 70.

  Then, when the NFC communication enable button 110 is operated, the NFC communication can be performed, that is, the NFC communication is enabled. That is, when the NFC communication enable button 110 is operated, the NFC communication is changed from the disabled state to the enabled NFC communication state. In other words, the operation mode (an example of the execution mode of the present invention) of the MFP 10 changes from a mode in which NFC communication cannot be performed to a mode in which NFC communication can be performed. The NFC communication may be enabled or disabled based on an input from the button input unit 18 or may be switched according to the state of the MFP 10. In the latter case, for example, as described above, NFC communication is disabled when the MFP 10 is displaying the home screen, and NFC communication is performed when the facsimile transmission function using NFC communication is selected. It is good to switch so that it may become effective.

  In addition, when the facsimile transmission function is selected via the button input unit 18 in a state where NFC communication is enabled, the panel 16 is touched as shown in FIG. Is displayed (hereinafter also referred to as an activation display screen). When the user brings the mobile phone 70 close to the antenna unit 80 and NFC communication is established, data related to the facsimile number is transmitted from the mobile phone 70 to the MFP 10 using the NFC communication. Then, the MFP 10 performs facsimile transmission processing of document data to the facsimile number.

  As described above, the MFP 10 can perform facsimile transmission or the like simply by bringing the mobile phone 70 close to the antenna unit 80, which is very convenient. However, operation keys 100, 102, and 104 are arranged next to the antenna unit 80. For this reason, when the user brings the mobile phone 70 close to the antenna unit 80, the user may accidentally operate the operation keys 100, 102, and 104. In such a case, the MFP 10 may not operate as intended by the user, and operability may be reduced.

  Incidentally, the distance between the antenna unit 80 and the operation keys 100, 102, and 104 is determined by the user's finger holding the cellular phone 70 or the cellular phone 70 when the cellular phone 70 is brought close to the antenna unit 80. Is a distance that can be detected by the operation keys 100, 102, and 104, and is appropriately set depending on the device design.

Specifically, for example, when the user intends to perform facsimile transmission using NFC communication and brings the mobile phone 70 close to the antenna unit 80, the user's finger etc. There are cases where the operation key 102 is operated by touching or approaching the operation key 102 (an example of the stopping means of the present invention). The operation key 102 is a home key. When the operation key 102 is operated, the MFP 10 displays the home screen as the display screen as described above, and the NFC communication is disabled. That is, the user operation on the operation key 102 becomes a user operation for changing the operation mode, and the NFC communication is changed from the enabled state to the disabled state. For this reason, even when the mobile phone 70 is brought close to the antenna unit 80, NFC communication is not established, and data relating to a facsimile number using NFC communication is not transmitted from the mobile phone 70 to the MFP 10. That is, even if the user intends to perform facsimile transmission using NFC communication and brings the mobile phone 70 close to the antenna unit 80, facsimile transmission using NFC communication is not performed. Note that the home key is a key for the MFP 10 to transition to a state in which it waits for reception of a facsimile or a state in which it waits for input from the button input unit 18.

  In view of this, the MFP 10 delays the response of predetermined buttons such as the operation keys 100, 102, and 104 in a state where the NFC communication is enabled. That is, the reaction time, which is the time from when the button is operated until the processing according to the button operation starts, is greater than the reaction time when NFC communication is disabled when NFC communication is enabled. It is long.

  Specifically, a method for detecting an input medium using the operation keys 100, 102, and 104 will be described first. The operation keys 100, 102, and 104 have a substrate (not shown), and the substrate can detect a change in capacitance. For this reason, when an input medium such as a finger approaches the operation keys 100, 102, and 104, a change in electrostatic capacitance is detected by the substrate. The capacitance change value detected by the substrate is treated as a detection value, and the detection value is amplified by a predetermined multiple. Then, it is determined whether or not the amplified value exceeds the threshold value. If the amplified value exceeds the threshold value, it is determined that the operation keys 100, 102, and 104 are operated. When it is determined that the operation keys 100, 102, and 104 are operated, the board sends a signal to that effect to the CPU 12. When the CPU 12 receives the signal, the CPU 12 outputs a processing start instruction to a processing unit such as the printer 20, the scanner 22, or the modem 24. As a result, processing corresponding to each operation key 100, 102, 104 is started in the processing unit. That is, the time from when the amplified value exceeds the threshold to when processing corresponding to each operation key 100, 102, 104 is started is the reaction time.

  This reaction time is assumed to be an extremely short time (in the first embodiment of the present invention) since it is assumed that an operation of the operation button due to the approach to the antenna unit 80 of the mobile phone 70 cannot normally occur in a state where NFC communication is disabled. An example of two reaction times). That is, in a state where NFC communication is disabled, immediately after the button is operated, processing according to the button operation is started. Note that the second reaction time is not set, and may be a reaction time that may inevitably occur for convenience of processing even when the MFP 10 is designed so that the reaction time does not occur. On the other hand, when NFC communication is enabled, the reaction time is set to a predetermined set time (an example of the first reaction time of the present invention). That is, in a state in which NFC communication is enabled, processing according to the button operation is started after a set time has elapsed since the button was operated. The set time is set to be longer than the reaction time in a state where NFC communication is disabled.

  Here, a method for setting the reaction time in a state in which NFC communication is enabled as the set time will be described. Specifically, the operation key 100, 102, 104 waits for a signal to be sent to the CPU 12 until the set time elapses after determining that the button is operated, and sends the signal to the CPU 12 after the set time elapses. As another method, the CPU 12 that has received a signal from the board waits for the processing start instruction to be transmitted to the processing unit until the set time elapses, and outputs the process start instruction to the processing unit after the set time elapses. It is also possible to use these two methods in combination. With any of these methods, it is possible to set the reaction time in a state in which NFC communication is enabled as the set time. In any case, the set time can be measured by measuring the waveform between the substrate and the CPU 12 or between the CPU 12 and the processing unit.

By setting the reaction time when NFC communication is enabled to a time longer than the reaction time when NFC communication is disabled, the detected button operation is It is possible to determine whether or not the operation is erroneous due to the approach of the telephone 70 to the antenna unit 80. Specifically, whether or not the distance between the mobile phone 70 and the antenna unit 80 is within the wireless communication range of the mobile phone 70 before the set time elapses after the button operation is detected, that is, It is determined whether or not NFC communication is started, and when NFC communication is started, it is determined that the button operation is an erroneous operation due to the proximity of the cellular phone 70 to the antenna unit 80. That is, when the user brings the mobile phone 70 close to the antenna unit 80, it is determined that the button operation is erroneously performed by the user's finger or the mobile phone 70. For this reason, when NFC communication is started before the set time has elapsed after the predetermined button is operated, processing based on the predetermined button operation is limited.

  Specifically, in a state where NFC communication is enabled, the reaction time of a predetermined operation button is set to a set time. Then, when the mobile phone 70 is brought close to the antenna unit 80 of the MFP 10 in a state in which NFC communication is enabled, the operation key 102 as a home key is erroneously operated, and a set time elapses from the button operation. When the NFC communication is started before, the operation mode of the MFP 10 does not change to a state in which the NFC communication is invalidated. That is, the NFC communication is kept valid. As a result, NFC communication is established, and data relating to the facsimile number using NFC communication is transmitted from the mobile phone 70 to the MFP 10. Then, the MFP 10 performs facsimile transmission processing of document data to the facsimile number. That is, it is possible to perform facsimile transmission using NFC communication according to the user's intention.

  However, when the user brings the mobile phone 70 close to the antenna unit 80, there are cases where the user performs button operations with consciousness. For example, an arbitrary button may be operated with the other hand while the cellular phone 70 is brought close to the antenna unit 80 with one hand. In such a case, NFC communication starts before the set time elapses from the button operation, and processing based on the button operation is limited. However, the button operation with the limited process is a button operation according to the user's intention, and it is not preferable to limit the process according to the button operation.

  For this reason, when the process according to the button operation is restricted, the release button 112 is displayed on the panel 16 of the MFP 10 as shown in FIG. The cancel button 112 is an operation button for canceling the process restriction according to the button operation. When the cancel button 112 is operated, the process restriction according to the button operation is canceled. That is, even if the NFC communication is started before the set time has elapsed since the button operation, the process according to the button operation is executed. Thereby, it becomes possible to perform button operation according to a user's intention. Note that when the release button 112 is not operated, the restriction of processing according to the button operation is not released. That is, the process according to the button operation is not executed.

  In addition, when NFC communication does not start until a set time elapses after a predetermined button is operated, it is assumed that the button operation is not an operation when the user brings the mobile phone 70 close to the antenna unit 80. The That is, the button operation is assumed to be an operation according to the user's intention. For this reason, when NFC communication does not start until a set time elapses after a predetermined button is operated, processing based on the predetermined button operation is performed.

  Specifically, for example, in the MFP 10 in a state where the NFC communication is enabled, when the operation key 102 is operated and the NFC communication does not start until a set time elapses after the button operation, the operation mode of the MFP 10 is: The state changes to a state where NFC communication is disabled. Thereby, the process according to a user's intention is performed.

In addition, the above-described control for preventing erroneous operation of the operation buttons (hereinafter, sometimes referred to as erroneous operation prevention control for short) is performed on the operation buttons related to NFC communication. Specifically, an erroneous operation is performed on a button for operating a communication state of NFC communication, a button for setting NFC communication, a button for changing to a state for exchanging data by NFC communication, or the like. Prevention control is performed. On the other hand, no erroneous operation prevention control is performed on operation buttons that are not related to NFC communication, such as buttons for changing the brightness of the panel 16 and buttons for setting that are not related to NFC communication. That is, when an operation button not related to NFC communication is operated in a state where NFC communication is enabled, processing according to the button operation starts immediately after the button operation without waiting for the set time to elapse. . Thereby, it is possible to operate the operation buttons that do not affect the NFC communication as usual.

<Control program>
The change of the reaction time described above is performed by executing the control program 50 in the CPU 12. Specifically, a flow for suppressing erroneous button operation when the mobile phone 70 is brought close to the antenna unit 80 will be described with reference to FIGS. 6 to 9. This program is executed when the power of the MFP 10 is turned on. In parallel with the execution of this program, the MFP 10 executes NFC communication with the mobile phone 70 when NFC communication is enabled and the mobile phone 70 is brought close to a predetermined distance at which communication with the antenna unit 80 is possible. To do.

  In the control program 50, first, the CPU 12 determines whether or not NFC communication is enabled (step (hereinafter abbreviated as “S”) 100). If NFC communication is not activated (NO in S100), the process in S100 is repeated. On the other hand, when NFC communication is enabled (YES in S100), the reaction time of all buttons (hereinafter, may be abbreviated as all input buttons) of the button input unit 18 is set to the set time. It is set (S102). For example, 2 seconds is set as the set time, and the design can be changed as appropriate. Then, the CPU 12 determines whether or not any of the input buttons is operated (S104).

  If any of the input buttons has been operated (YES in S104), the CPU 12 determines whether the operated button is a button related to NFC communication (S106). If the operated button is a button related to NFC communication (YES in S106), information related to the operated button is stored (S108). For example, when the operation key 102 is operated, data indicating that the operation key 102 has been operated is stored.

  Then, the CPU 12 determines whether or not a set time has elapsed since the button was operated (S110). If the set time has not elapsed since the button was operated (NO in S110), whether or not NFC communication has started, that is, whether or not the antenna unit 80 has received a radio wave used for NFC communication. CPU 12 determines (S112). If NFC communication has not started (NO in S112), the process returns to S110.

  On the other hand, when NFC communication is started (YES in S112), the release button 112 is displayed on the panel 16 (S114). Next, the CPU 12 determines whether or not the release button 112 has been operated (S116). If the release button 112 is not operated (NO in S116), the stored information regarding the operation button is discarded (S118). And the process according to NFC communication is performed (S120). For example, a facsimile number using NFC communication is received from the mobile phone 70, and facsimile transmission processing is performed using the facsimile number as a transmission destination. With the above processing, the control program 50 ends.

If the release button 112 is operated in S116 (YES in S116), processing corresponding to the information related to the operation button stored in S108 is performed (S122). Specifically, for example, when the operation key 102 is operated, the operation mode of the MFP 10 is changed to a state where NFC communication is disabled. Then, a screen corresponding to the operated button is displayed on the panel 16 (S124). Specifically, for example, when the operation key 102 is operated, the home screen is displayed on the panel 16. With the above processing, the control program 50 ends.

  If the set time has elapsed since the button was operated in S110 (YES in S110), the process proceeds to S122, and the subsequent processing is performed.

  If the button operated in S106 is not a button related to NFC communication (NO in S106), the process proceeds to S122 without waiting for the set time to elapse, and the subsequent processing is performed.

  Further, if any of the input buttons is not operated in S104 (NO in S104), the antenna unit 80 receives NFC communication, that is, the radio wave used for NFC communication. It is determined by the CPU 12 whether or not it has been (S126). If NFC communication has not started (NO in S126), the process returns to S100. On the other hand, if NFC communication has started (YES in S126), the process proceeds to S120, and the subsequent processing is performed.

<Functional configuration of CPU>
The CPU 12 that executes the control program 50 can be considered to have a functional configuration as shown in FIG. 1 in view of its execution processing. As can be seen from the figure, the CPU 12 includes a setting unit 130 (an example of the setting unit and setting means of the present invention), an execution unit 132 (an example of the execution unit of the present invention), and a restriction unit 134 (of the restriction unit of the present invention). An example), a display unit 136 (an example of a display unit of the present invention), a terminal command execution unit 138 (an example of a terminal command execution unit of the present invention), and a determination unit 140 (an example of a determination unit of the present invention). doing.

Second Embodiment
An operation of the MFP 10 according to the second embodiment will be described. Note that the configuration of the MFP 10 in the second embodiment is the same as the configuration of the MFP 10 in the first embodiment, and a description thereof will be omitted here.

In the MFP 10 according to the first embodiment, the reaction times of both the operation buttons not related to NFC communication and the operation buttons related to NFC communication are set to the set time (S102). When an operation button not related to NFC communication is operated (NO in S106), the process according to the button operation is executed immediately after the button operation without waiting for the set time to elapse (S122). It is possible to set only the reaction time of the operation buttons related to NFC communication as the set time. The flow for changing the reaction time in the MFP 10 according to the second embodiment will be described with reference to FIG. However, this flow is the same as the flow shown in FIGS. 6 to 8 except the flow shown in FIG. 6, and the flow shown in FIG. 9 corresponds to the flow shown in FIG. Therefore, only the flow shown in FIG. 9 will be described in a simplified manner.

  In the flow shown in FIG. 9, the CPU 12 determines whether or not NFC communication is enabled (S200). If NFC communication is not activated (NO in S200), the process of S200 is repeated. On the other hand, when NFC communication is enabled (YES in S200), the CPU 12 determines whether or not all the operation buttons of the button input unit 18 are operation buttons related to NFC communication, and the button The reaction time of the operation buttons related to NFC communication among all the operation buttons of the input unit 18 is set to the set time (S204). And the process after S206 is performed. The processing after S206 is the same as the processing after S104 shown in FIG. 6 except for the processing of S106.

  By executing the above flow, only the reaction time of the operation button related to NFC communication is set as the set time, and the reaction time of the operation button not related to NFC communication is maintained at the second reaction time. As a result, the MFP 10 in the second embodiment can obtain the same effects as those of the MFP 10 in the first embodiment.

<Third Embodiment>
An operation of the MFP 10 according to the third embodiment will be described. Note that the configuration of the MFP 10 in the third embodiment is the same as the configuration of the MFP 10 in the first embodiment, and a description thereof will be omitted here.

  In the MFP 10 according to the second embodiment, the response time of the operation buttons related to NFC communication is set as the set time (S202, S204), but the response time of any operation button among all the input buttons is set as the set time. Can be set.

  Specifically, the MFP 10 according to the third embodiment is provided with a first restriction button (not shown), a second restriction button (not shown), and a third restriction button (not shown). The first limit button is a button for executing the erroneous operation prevention control for all the input buttons. When the first limit button is operated, the reaction time of all the input buttons is set to the set time. The second limit button is a button for executing an erroneous operation prevention control for the buttons provided on the upper surface of the casing 82 among all the input buttons. When the second limit button is operated, the casing 82 is operated. The reaction time of the button provided on the upper surface of the is set to the set time. The third restriction button is a button provided on the top cover 86 among all the input buttons, that is, a button for executing an erroneous operation prevention control for the operation keys 100, 102, 104. When operated, the reaction time of the operation keys 100, 102, 104 is set to the set time. The MFP 10 according to the third embodiment is also provided with an operation button (not shown) for prohibiting erroneous operation prevention control, and when the operation button is operated, the reaction time of all input buttons Is not set at the set time.

  A flow for changing the reaction time in the MFP 10 according to the third embodiment will be described with reference to FIGS. 10 and 11. However, this flow is the same as the flow shown in FIGS. 6 to 8 except the flow shown in FIG. 6, and the flows shown in FIGS. 10 and 11 correspond to the flow shown in FIG. Therefore, only the flow shown in FIGS. 10 and 11 will be described in a simplified manner.

In the flow shown in FIG. 10, the CPU 12 determines whether or not NFC communication is enabled (S300). If NFC communication is not enabled (NO in S300), the process in S300 is repeated. On the other hand, if NFC communication is enabled (YES in S300), a target operation button detection subroutine is executed (S302). In the target operation button detection subroutine, as shown in FIG. 11, the CPU 12 determines whether or not to perform the erroneous operation prevention control for all the input buttons (S304). That is, the CPU 12 determines whether or not the first limit button is operated. When the first restriction button is not operated (NO in S304), the CPU 12 determines whether or not to perform the erroneous operation prevention control for the operation buttons provided on the upper surface of the housing 82 among all the input buttons. Determination is made (S306). That is, the CPU 12 determines whether or not the second limit button is operated.

  When the second restriction button is not operated (NO in S306), the operation buttons provided on the top cover 86 among all the input buttons, that is, the operation keys 100, 102, 104 are subjected to the erroneous operation prevention control. The CPU 12 determines whether or not to execute (S308). That is, the CPU 12 determines whether or not the third limit button is operated.

  When the third restriction button is operated (YES in S308), the CPU 12 determines whether or not the operation button is provided on the top cover 86 (S310). When the operation button is provided on the top cover 86 (YES in S310), the processing of this subroutine is finished, and the processing after S314 of the main routine is executed. The processing after S314 is the same as the processing after S102 shown in FIG. 6 except for the processing at S106.

  If the operation button is not provided on the top cover 86 in S310 (NO in S310), or if the third restriction button is not operated in S308 (NO in S308), the processes after S122 shown in FIG. Is executed.

  If the second limit button is operated in S306 (YES in S306), the CPU 12 determines whether the operation button is provided on the upper surface of the housing 82 (S312). When the operation button is provided on the upper surface of the housing 82 (YES in S312), the processing after S314 of the main routine is executed. On the other hand, when the operation button is not provided on the upper surface of the housing 82 (NO in S312), the processing after S122 shown in FIG. 7 is executed.

  If the first limit button is operated in S304 (YES in S304), the processing after S314 of the main routine is executed.

  By executing the above flow, it is possible to set the reaction time of any operation button among all the input buttons to the set time. At this time, if the first limit button is operated, it is possible to reliably prevent an erroneous button operation. When the second restriction button is operated, it is possible to prevent an erroneous operation with respect to a button that is likely to be erroneously operated when the cellular phone 70 is brought close to the antenna unit 80. When the third restriction button is operated, it is possible to prevent an erroneous operation on a button that is particularly likely to be erroneously operated when the mobile phone 70 is brought close to the antenna unit 80.

<Modification>
In addition, this invention is not limited to the said embodiment, It is possible to implement in the various aspect which gave various change and improvement based on the knowledge of those skilled in the art. Specifically, for example, in the above-described embodiment, the operation keys 100, 102, and 104 are employed as operation buttons disposed next to the antenna unit 80. That is, the capacitive touch sensor is adopted as the target of the erroneous operation prevention control, but is not limited to the touch sensor, and a mechanical operation button can be adopted. Moreover, it is possible to employ a touch sensor of a method other than the electrostatic capacitance method. Specifically, various types of touch sensors such as a surface acoustic wave method, a resistance film method, an electromagnetic induction method, an infrared method, and the like can be employed.

  In the above embodiment, the time from when the amplified value exceeds the threshold until the processing corresponding to the operation button starts is the reaction time, but the capacitance change value is detected. The time from the start of the process according to the operation key to the start of the process according to the operation key from the time when the amplified value exceeds the threshold and then falls below the threshold to the time when the process according to the operation key starts Is possible. In the case of a mechanical operation button, the time from when the input medium comes into contact with the operation button to when processing corresponding to the operation button starts, from when the input medium comes into contact with the operation button and after being separated from the operation button The time until the processing corresponding to the operation button starts can be set as the reaction time.

  In addition, as described above, the button input unit 18 includes a plurality of types of operation buttons such as a capacitive touch key, a pressure-sensitive touch panel, and a mechanical key. Although the technique of the present invention is applied to the operation buttons, the technique of the present invention can be applied only to a capacitive touch key. That is, it is possible to execute the erroneous operation prevention control only for the capacitive touch key. When the erroneous operation prevention control is executed only for the capacitance type touch key, for example, in the flow shown in FIG. 6, when any of the input buttons is operated in S104. (YES in S104), the CPU 12 determines whether or not the operated button is a capacitance type touch key, and the operated button is a capacitance type touch key. In addition, the processing after S106 is executed. If the operated button is not a capacitive touch key, the process proceeds to S122.

  Further, in the above embodiment, the reaction time of the operation button at the time of executing the erroneous operation prevention control, that is, the time from when the operation button is operated until the processing based on the operation is performed is 2 seconds. It is possible to change the reaction time of the operation button when executing the operation restriction control according to the type of the button. Specifically, for example, the response time when executing the erroneous operation prevention control of the capacitive touch key is 2 seconds, and the reaction time when executing the erroneous operation prevention control of the pressure-sensitive touch panel or mechanical key is 1 second. It is possible. Capacitive touch keys can be operated without touching the touch keys, but pressure sensitive touch panels and mechanical keys cannot be operated without touching the panels and keys. . That is, the time required to operate the pressure-sensitive touch panel and the mechanical key is longer than the time required to operate the capacitive touch key. In consideration of this, it is preferable to set the reaction time when performing the erroneous operation prevention control of the capacitive touch key to be longer than the reaction time when executing the erroneous operation prevention control of the pressure-sensitive touch panel or the mechanical key. Of course, depending on the layout of each key, it is possible to set the reaction time when performing an erroneous operation prevention control for capacitive touch keys to be shorter than the reaction time when performing an erroneous operation prevention control for a pressure-sensitive touch panel or mechanical key. is there.

  Moreover, in the said Example, although the button input part 18 functions as a reception part, the operation key etc. which are displayed on the panel 16 may function as a reception means.

  In the above embodiment, the response time of the operation button is changed when executing facsimile communication using NFC communication. However, when executing various processes such as printing using NFC communication, the operation time is changed. A change in the button reaction time may be made.

In the above embodiment, when the processing based on the button operation is restricted, the release button 112 is displayed on the panel 16, but is disposed on the side of the existing operation button, for example, the top cover 86. An image indicating that the restriction on processing based on button operation can be released by operating a specific operation button may be displayed on the panel 16.

Further, for example, in the above-described embodiment, the MFP 10 is employed as a communication device that performs NFC communication with the mobile phone 70, but various devices such as a printing machine and a PC (abbreviation of personal computer) may be employed.

  Further, although the mobile phone 70 is employed as an information processing terminal that performs wireless communication 60 with the MFP 10, a tablet device, a smartphone, or the like may be employed.

  In the above-described embodiment, NFC wireless communication is employed as the proximity wireless communication. However, wireless communication such as the Transfer Jet method may be employed.

  In the above-described embodiment, an example in which the processing shown in FIGS. 6 to 11 is executed by the CPU 12 has been described. However, these processings are not limited to the CPU 12, and may be executed by an ASIC or other logical integrated circuit. These processes may be executed by the cooperation of the CPU 12, the ASIC, and other logic integrated circuits.
