Description

  The present invention relates to an image processing apparatus such as a copying machine, a printer, an MFP (Multi Function Peripheral) which is a multifunction digital image forming apparatus, a power saving method of the same apparatus, and a power saving control program.

  In general, the above-described MFP or the like having a power saving mode is configured to perform a return operation in accordance with a predetermined release condition when returning from the power saving mode to the normal mode.

  As an image processing apparatus having such a power saving mode, any of the keys on the operation panel unit can be pressed (touched) in the power saving mode state in which the display on the operation panel unit such as a touch panel is erased. An image processing apparatus in a so-called all-key return mode is known that is configured to release the power saving mode and return to the normal mode using the input other than the key operation as a condition for releasing the power saving mode. .

  However, although this image processing apparatus has relatively good operability, it is necessary to continue power supply to the operation panel control CPU for detecting key input on the operation panel unit, and sufficient power saving is required. There is a problem that the effect cannot be obtained.

  In view of this, an image forming apparatus has been proposed in which power supply to the operation panel unit is cut off to reduce power consumption, and the power-saving mode is canceled when the power button is pressed. (For example, patent document 1).

  The operation panel unit 11 includes a panel unit control CPU 110, which is a first CPU, a display unit 110, a key unit 112, a power key (switch) (not shown), and the like.

  The panel unit control CPU 110 receives an operation of the operation panel unit 11 by a user and notifies the state control CPU 121 which is the second CPU in the state control unit 12 of the apparatus.

  The display unit 111 is composed of, for example, a touch panel type liquid crystal display device or the like, and can be input by a user.

  The key unit 112 has a numeric keypad, a start key, and the like.

  The state control unit 12 includes a state control CPU 121 that detects and controls a plurality of states of the MFP (also referred to as an apparatus) 1, the number of returns from the power saving mode for each release factor such as document setting and panel operation, and a job history (user history). Use history), a timing unit 123 for discriminating between an operation time zone and a pause time zone of the MFP 1, and a plurality of detection units (such as the fingerprint authentication device 13) for canceling the power saving mode. Are provided with energizing means 124 as power feeding devices for energizing.

  In addition to functioning as a means for detecting the transition of the MFP 1 to the power saving mode, the state control CPU 121 determines an optimum energization state according to the apparatus state when the MFP 1 shifts to the power saving mode, and energizes the energization means 124. It also functions as a control means for continuing.

  The fingerprint authentication device 13 functions as a detection unit corresponding to one cancellation condition for canceling the power saving mode, reads the user's fingerprint information at the time of login, and transmits it to the state control CPU 121 in the state control unit 12. .

  As described above, the scanner unit 2 has a scanning function of reading an image of a document set by a user. When the document is set, a document set detection signal is sent via a document set detection sensor 19 to the state control unit. 12 to the state control CPU 121. In addition, when a start button (not shown) is pressed, the state control CPU 121 in the state control unit 12 starts reading a document and transmits the read image to the print unit 7.

  The FAX unit 14 notifies the state control CPU 121 in the state control unit 12 when the reception of the document image data is detected. At this time, the state control CPU 121 starts receiving a document image.

  When receiving document image data from a terminal device or the like, the network unit 15 notifies the state control CPU 121 in the state control unit 12. At this time, the state control CPU 121 stores the received document image data in the memory 122 of the state control unit 12.

  The print unit 7 prints image data input from each unit.

  The card reader 16 detects, as a detection means corresponding to one release condition for releasing the power saving mode, when a user touches or brings a card on which his / her identification information is recorded, and detects the card. It functions as a sensor that reads identification information.

  The paper detection sensor 17 detects the presence / absence of paper, which is one of the apparatus states, as detection means corresponding to one release condition for releasing the power saving mode.

  The jam detection sensor 18 detects the presence or absence of a paper jam, which is one of the apparatus states, as detection means corresponding to one release condition for releasing the power saving mode.

  The document set detection sensor 19 detects that a document is set on the document table 2A of the scanner unit 2 as detection means corresponding to one cancellation condition for canceling the power saving mode.

  The MFP 1 has a plurality of power saving modes with different power supply states to the respective units. One of them is a power saving mode in which the display unit 111 of the operation panel unit 11 is turned off and the power consumption is lower than that in the normal mode. In this power saving mode, the release conditions for returning to the normal mode are all in the key unit 112. This is an all-key mode when any key is pressed.

  The other power saving mode has a higher power saving effect when power is not supplied to the operation panel unit 11, and the release condition when returning to the normal mode is replaced with the panel control CPU 110 in the power cut-off state. This is a one-key mode when the state control CPU 121 detects a specific release signal. In this power saving mode, since power supply to the panel control CPU 110 is interrupted, the power saving mode is not canceled even if a key on the operation panel is pressed.

  Next, description will be given by taking as an example a one-key mode limited to the specific release signal.

  In general, when the MFP 1 is operating in the normal mode and the state where there is no device operation continues, the MFP 1 shifts to the power saving mode. However, in this embodiment, as shown in FIG. Thus, a plurality of power saving modes and release conditions are set.

  In FIG. 3, for example, when a touch-and-print job is stored in the MFP 1, only the card reading device 16 is energized while the other detection devices are de-energized during the power saving mode. As a condition for canceling the power saving mode, touching the card with the card reader 16, in other words, detecting the card with the card reader 16 is set.

  Further, when the device state is no paper, only the paper detection sensor 17 is energized during the power saving mode and the other detection devices are set to be de-energized. It is set that the presence of paper is detected by the sensor 17.

  Further, when the device state is a paper jam, the jam detection sensor 18 is energized only during the power saving mode and the other detection devices are de-energized. 18 indicates that no jam is detected.

  Further, when the original is set and left unattended, only the original set detection sensor 19 is energized during the power saving mode, and the other detection devices are set to be de-energized. As the release condition, it is set that the original set detection sensor 19 detects another original set.

  Further, when the MFP 1 is configured to include the fingerprint authentication device 13 (indicated as “device configuration” in FIG. 3), only the fingerprint authentication device 13 is energized during the power saving mode, The detection device is set to be de-energized. As a condition for canceling the power saving mode, the user touches the fingerprint authentication device 13 with a finger, in other words, the finger is set by the fingerprint authentication device 13. Is set to be detected.

  Also, if the user's usage history includes a lot of power saving mode release histories due to the document set, only the document set detection sensor 19 is energized while the other detection devices are de-energized during the power saving mode. As a condition for canceling the power saving mode, it is set that the document set detection sensor 19 detects another document set again.

  In addition, when the time zone is a preset pause time zone, the time measuring means 123 is energized, and the power saving mode is released when the release time is reached.

  When the device state is other than the above, the power saving mode is canceled by operating one specific key such as a power switch.

  As described above, the detection means for detecting the release signal is set based on the condition regarding at least one of the type of job to be executed, the state of the MFP 1, the operation history, the operation time zone, and the setting of the MFP 1. Among the multiple power saving modes with different release conditions, the power saving mode with the best operability is set for canceling the power saving mode, and the release signal is always fixed to one detection means while obtaining an efficient power saving effect. Compared with the case where it exists, the operativity at the time of cancellation | release from a power saving mode can be improved.

  FIG. 4 is a flowchart showing a flow of power saving mode selection processing in the MFP 1. This process is executed when the state control CPU 121 of the MFP 1 operates according to a program recorded in a recording medium such as a ROM or a memory 122 (not shown).

  In FIG. 4, in step S <b> 1, when the MFP 1 is operating in the normal mode, a time lapse is measured as to whether or not the state in which there is no device operation continues for a predetermined time set by the user, and the state in which there is no device operation continues for a predetermined time. If the time is up, in step S2, determination of a power saving mode to be shifted from among a plurality of different power saving modes having different release conditions starts, and the process proceeds to step S3.

  The transition process to the power saving mode is called repeatedly by polling or timer interruption.

  In step S3, it is determined whether or not the next job is a touch and print job in order to determine the power saving mode to be transferred. If the next job is not a touch and print job (NO in step S3), the process proceeds to step S5. If the next job is a touch-and-print job (YES in step S3), in step S4, touching the card to the card reader 16 is set as a condition for canceling the power saving mode, and then the process proceeds to step S18. Transition to power saving mode. In this mode, only the components necessary for detection of the release signal such as the card reader 16 and the state control CPU 121 are energized to enter a power supply state.

  In step S5, it is determined whether or not the fingerprint authentication device 13 is attached. If the fingerprint authentication device 13 is not attached (NO in step S5), the process proceeds to step S7, and the fingerprint authentication device 13 is attached. If the answer is YES (YES in step S5), in step S6, touching the fingerprint authentication device 13 with a finger is set as a condition for canceling the power saving mode, and then the process proceeds to step S18 to shift to the power saving mode.

  In step S7, it is determined whether or not the user often releases the power saving mode using the document set. If the user does not frequently cancel the power saving mode using the document set (NO in step S7). If the user often proceeds to step S9 and cancels the power saving mode using the document set (YES in step S7), in step S8, the detection of the document set is set as a condition for canceling the power saving mode, and then the power saving mode is set. Enter mode.

  In step S9, it is determined whether or not the MFP 1 is currently in the operating time zone. If the operating time zone is not the operating time zone (NO in step S9), the process proceeds to step S11, and if it is the operating time zone (step S9). In step S10, the detection of the document set is set as a condition for canceling the power saving mode, and then the process proceeds to step S18 to shift to the power saving mode.

  In step S11, it is determined whether or not there is paper in the paper feed tray. If there is paper in the paper feed tray (NO in step S11), the process proceeds to step S13, and if there is no paper in the paper feed tray (in step S11). (YES) In step S12, the detection of “paper present” after the paper is set in the paper feed tray is set as a condition for canceling the power saving mode, and then the process proceeds to step S18 to shift to the power saving mode.

  In step S13, it is determined whether or not there is a paper jam. If it is not in the paper jam state (NO in step S13), the process proceeds to step S15. If it is in a paper jam state (YES in step S13), a jam is detected in step S14. After the detection of “no jam” after the processing is set as a condition for canceling the power saving mode, the process proceeds to step S18 to shift to the power saving mode.

  In step S15, it is determined whether or not the document set is left as it is. If the document set is not left as it is (NO in step S15), the process proceeds to step S17. In step S16, the detection of the document set is set as a condition for canceling the power saving mode, and then the process proceeds to step S18 to shift to the power saving mode.

  In step S17, except for the above-described conditions, after predetermined 1-key operation detection is set as a canceling condition, the process proceeds to step S18 and shifts to the power saving mode (1-key mode).

  Note that the above control and processing may be performed even in the power saving mode.

  Next, another embodiment of the present invention will be described.

  In this embodiment, the MFP 1 has an all-key mode power saving mode (first power saving mode) in addition to the above-described one key mode power saving mode (second power saving mode).

  In the power saving mode of the all-key mode, the operation panel unit control CPU 110 detects a key operation as a condition for canceling the power saving mode, and for this purpose, power is supplied to the operation panel unit control CPU 110 even during the power saving mode.

  On the other hand, in the power saving mode of the 1-key mode, the state control CPU 121 detects the cancellation signal of the power saving mode via each detection device such as the fingerprint authentication device 13 and the card reader 16, and for this reason, the operation panel unit is in the power saving mode. Power supply to the control CPU 110 becomes unnecessary, and the power saving effect is great.

  Whether to shift to all-key mode or 1-key mode, in other words, to set the power-saving mode release condition, the type of job to be executed, the status of the device, the operation history of the device, the operating time zone, It is determined based on at least one of the settings of the own device.

For example, the trigger for returning from the power saving mode of the MFP 1 to the normal mode is when the next occurrence is detected.
(1) A document is set on the document table 2A of the scanner unit 2 in order to read the document image.
(2) Key depression of the key unit 111 on the operation panel unit 11 or ON / OFF of the sub power key.
(3) Print image data from the user terminal (PC).
(4) FAX communication.

   When the MFP 1 receives a job from the user PC via the network, the job is stored and accumulated in the memory 122 as shown in FIG.

  If this job is a touch-and-print job, authentication is performed by the user touching the card reader 16 with the card, and this touch operation triggers the cancellation of the power saving mode, so that no panel operation occurs. Thus, when the next job is a job that does not cause panel operation, the MFP 1 selects the 1-key mode.

  If the device status is “No Paper”, “Paper Jam”, or “Abnormal Occurrence”, immediate action is desired, so return work and panel operation are required by user operation, and all key modes are selected. .

  Further, when the MFP 1 is configured to include the fingerprint authentication device 13, the 1-key mode in which only the fingerprint authentication device 13 is energized and the other detection devices are de-energized during the power saving mode. The setting is made, and the condition for canceling the power saving mode is that the user touches the finger with the fingerprint authentication device 13, in other words, that the finger is detected by the fingerprint authentication device 13. Has been.

  Control of the power saving mode based on the usage history of each user time zone will be described with reference to FIGS.

   FIG. 6A shows an example in which 24 hours from 7:00 am to the next morning are divided by working, lunch break, overtime, etc. FIG. 6B shows (1) document set on the scanner, (2 For the panel operation, (3) PC printing, and (4) FAX transmission, the amount (number of times) for each time zone is shown.

  FIG. 6C shows the number of jobs for each time zone, and FIG. 6D shows the selected state of the power saving mode for each time zone.

  Thus, each time the MFP 1 returns from the power saving mode, the occurrence time and the return factor (power saving mode release factor) are stored, and history management is performed.

  From this history, it is possible to grasp the usage of the user from the frequently used return factor to the less frequently used return factor, and it is also possible to grasp the return status for each hour. From the data in FIG. 6B, the user's usage history is mostly restored by the original set in the above (1). In this case, the 1-key mode is selected.

Based on the above information, when the time zone is divided at 10-minute intervals as shown in FIG. 6C, the time zone in which more than half of the maximum number of jobs occurs is the operating time zone of the MFP 1, and the rest is It is a resting period.
<Operating hours>
The order of the return factor with the highest number of times from the power saving mode is (1) Document setting on the scanner, (3) PC print, (4) FAX reception, and (2) Panel operation.

In this state, even if the user selects the all-key mode as in the conventional case, as a result of comparison between (1) original set and (2) panel operation as a return factor, (2) from the original set If there is a lot of return, if the return by panel operation does not occur for a certain period of time under the control of the FMP1, the 1-key mode with higher power saving effect is selected.
<Suspension hours>
In this time zone, even if the user has selected the all-key mode as in the prior art, the mode is switched to the one-key mode with higher power saving effect by the control on the MFP 1 side.

  As described above, based on at least one of the type of job to be executed, the status of the own device, the operation history of the own device, the operating time zone, and the setting of the own device, the release condition for return and the energized state Since different power saving modes (all key mode or one key mode) are selected, an effective power saving effect can be obtained without degrading the operability for the user.

  FIG. 7 is a flowchart showing the flow of power saving mode selection processing in the embodiment.

  In FIG. 7, in step S <b> 21, when the MFP 1 is operating in the normal mode, the elapsed time is measured to determine whether or not the state in which there is no device operation continues for a predetermined time set by the user, and the state in which there is no device operation continues for a predetermined time. If the time is up, in step S22, determination of a power saving mode to be shifted from among a plurality of different power saving modes is started, and the process proceeds to step S23.

  In step S23, it is determined whether or not the next job is a touch and print job in order to determine the power saving mode to be transferred. If the next job is not a touch and print job (NO in step S23), the process proceeds to step S24. If the next job is a touch-and-print job (YES in step S23), the 1-key mode is selected in step S29, and then the process proceeds to step S28 to shift to the power saving mode.

  In step S24, it is determined whether or not the fingerprint authentication device 13 is attached. If the fingerprint authentication device 13 is not attached (NO in step S24), the process proceeds to step S25, and the fingerprint authentication device 13 is attached. If (YES in step S24), after selecting the 1-key mode in step S29, the process proceeds to step S28, and shifts to the power saving mode.

  In step S25, it is determined whether or not the user often cancels the power saving mode by setting the document. If the user does not frequently cancel the power saving mode by setting the document (NO in step S25), the process proceeds to step S26. If the user frequently cancels the power saving mode by setting the original (YES in step S25), the 1 key mode is selected in step S29, and then the process proceeds to step S28 to shift to the power saving mode.

  In step S26, it is determined whether or not the MFP 1 is currently operating, and if it is not the MFP 1 operating time but a resting time (NO in step S26), in step S27, all key modes are selected, and step In S28, the power saving mode is entered. If it is the operation time zone of the MFP 1 (YES in step S26), after selecting the 1-key mode in step S29, the process proceeds to step S28 and shifts to the power saving mode.

  FIG. 8 is a flowchart showing the flow of mode switching processing during the power saving mode.

  During the power saving mode in step S31, the power saving mode switching determination is started in step S32.

  In step S33, it is determined whether or not the next job is a touch and print job in order to determine the power saving mode to be transferred. If the next job is not a touch and print job (NO in step S33), the process proceeds to step S34. If the next job is a touch and print job (YES in step S33), the 1-key mode is selected in step S39, and then the process proceeds to step S38 to shift to the power saving mode.

  In step S34, it is determined whether or not the fingerprint authentication device 13 is attached. If the fingerprint authentication device 13 is not attached (NO in step S24), the process proceeds to step S35, and the fingerprint authentication device 13 is attached. If (YES in step S34), after the 1-key mode is selected in step S39, the process proceeds to step S38 and shifts to the power saving mode.

  In step S35, it is determined whether or not the user often cancels the power saving mode by setting the document. If the user does not frequently cancel the power saving mode by setting the document (NO in step S35), the process proceeds to step S36. If the user frequently cancels the power saving mode by setting the original (YES in step S35), the user proceeds to step S38 after selecting the 1-key mode in step S39, and shifts to the power saving mode.

  In step S36, it is determined whether or not the MFP 1 is currently operating, and if it is not the MFP 1 operating time but a pause time (NO in step S36), the all-key mode is selected in step S37, and step S38. To switch to power saving mode. If it is the operating time zone of the MFP 1 (YES in step S36), after selecting the 1-key mode in step S39, the process proceeds to step S38 and shifts to the power saving mode.

  Next, another embodiment of the present invention will be described. In this embodiment, a priority is provided for the condition for canceling the power saving mode, and the power saving mode is selected according to this priority.

  FIG. 9 is a table showing the priority of release conditions.

  In FIG. 9, for which there are a plurality of power saving modes, which power saving mode is to be selected is selected according to a plurality of release conditions, but in order to cope with the case where the release conditions overlap, priority is set in the power saving mode selection. The power saving mode on the release condition side having a higher priority is selected.

   For example, even if the time zone is an operation time zone, if a touch and print job is received, the 1 key mode is selected. Select.

  Further, when the power saving state is in the all-key mode in the operation time zone, the power saving mode is switched to the 1-key mode when the idle time zone is reached.
