Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply control device for supplying commercial power to external equipment, and more particularly to a power supply control device suitable for realizing a service for supplying commercial power to a portable terminal or the like in a public telephone booth or the like. .

[0002]

2. Description of the Related Art In recent years, demand for communication such as transmission and reception of electronic mail using a public telephone device has been increasing. In response, many public telephone devices on the street corner have terminal ports for data communication. In addition, many mobile terminals have a built-in modem and support functions for performing data communication.

[0003] In spite of the fact that the use environment has been improved, the utilization of communication using public telephone devices is not progressing smoothly. Although various factors can be considered for this, one of them is that the battery duration during communication of the portable terminal is short. Since high-speed data communication involves large power consumption, it is disadvantageous to operate with a built-in power supply of a portable terminal.

[0004]

On the other hand, recent public telephone devices are basically connected to a commercial power supply and are operated by the commercial power. Therefore, a commercial power supply is drawn to a place where the public telephone device is installed.

[0005] However, conventionally, there has been no means prepared so that a user can use the commercial power supply.

Therefore, the present inventors have devised an energization control device for supplying commercial power to an external device such as a portable terminal using the commercial power supply.

[0007] It is necessary to receive the cost related to the power supply from the user side.

Conventionally, as a device for providing a power supply service for a fee, there is a device commonly called a “coin timer”.
The coin timer has a function of energizing for a predetermined time when a coin is inserted. The coin timer stores inserted coins therein.

Although it is possible to charge the power supply control device with coins like a coin timer, recent public telephone devices often charge only with a prepaid card. If such a power supply control device and such a public telephone device are installed together, there is a risk that coins may be stolen, and it may take time to collect coins.

[0010] In order to enable commercial power to be supplied for a fee and without cash, the present inventors have proposed:
Further, the power supply control device and the host device are connected via a communication line, and negotiation is performed with the host device. With this configuration, the above-described problem does not occur, and the host device can remotely control the communication control device.

That is, an object of the present invention is to provide an energization control device capable of supplying commercial power to an external device such as a portable terminal based on negotiation with a host device.

When the power-on time is notified from the host device,
A power supply control device characterized by having supply means for supplying commercial power to an external device only for the power supply time.

According to a third aspect of the present invention, there is provided an energization control device for supplying commercial power to an external device, the receiving device receiving an energization start instruction and a desired energization time. A communication unit for notifying the host device that determines whether or not to energize the power supply start time and the energization desired time when the reception unit receives the energization start instruction and the energization desired time; As a response to the notification by the above, when it is notified from the host device via the communication line that power can be supplied,
There is provided an energization control device characterized by having supply means for supplying commercial power to an external device for the desired energization time received by the reception means.

[0015] In the third aspect, the receiving means may be any one of a plurality of switches for designating a desired energization time provided in correspondence with each of a plurality of predetermined energization desired times. Depending on whether the switch is on,
The desired energization time can be received.

In any one of the first to third aspects, the receiving means receives the power supply start instruction depending on whether an attached power supply start instruction switch is on. be able to.

Further, in any of the first to third aspects, an outlet for outputting commercial power to be supplied to an external device may be added.

According to any of the first to third aspects, based on negotiation with the host device,
Commercial power can be supplied to an external device such as a mobile terminal. Also, from the viewpoint of the host device, the energization control device can be remotely controlled.
It is possible to manage the maintenance operation status of the power supply control device and to charge the user (for example, charge by debiting an account using a credit card or the like).

It is possible to further include transmission instruction means for instructing transmission to the host device.

Here, in particular, when the telephone device is a public telephone device, the telephone device may further include charging instruction means for instructing the public telephone device to perform charging in accordance with a power-on time.

Thus, the telephone line connected to the public telephone device can be used as it is for communication between the power supply control device and the host device. At this time, it is also possible for the user to pay for the call.

In Japan, a paid information providing service (commonly called "dial Q2") is currently being implemented.
Therefore, it is also possible to add the power supply cost to the call charge and collect the call charge using this paid information providing service.

It is an object of the present invention to provide a power supply control device for supplying commercial power to an external device such as a portable terminal based on negotiation with a host device. Since this kind of energization control device does not exist at present, consideration was also given to a case where it was not connected to the host device.

The energization control process is a process performed when the power supply of the energization control device 101 is turned on, and the arithmetic unit 105 activates and executes the energization control program stored in the memory 107. As shown in (1), in the energization control process, first, the modem 103, the memory 107, the display panel 108, and the relay device 109 are each initialized (step 301), and the energization control main process for actually performing the energization control is performed. (Step 303).

FIG. 4 is a flowchart of the energization control main process.

As shown in FIG. 4, in the energization control main process, first, an outlet connection waiting process for waiting for an external device to be set in the commercial power output unit 113 is performed (step 401). Step 401 is a step provided to prevent a user who does not intend to perform energization from activating the energization control device 101 by mistake and being charged, and the detailed processing content will be described with reference to FIG. It will be described later.

When an external device is set in the commercial power output unit 113, a process for waiting for input of a desired power supply time is performed to wait for a user to input a desired power supply time (step 40).
3). In the first embodiment, the user can select any one of 15 minutes and 30 minutes. The detailed processing content of step 403 will be described later with reference to FIG.

When the energization desired time input waiting process is completed,
Since the user has selected either 15 minutes or 30 minutes, the illumination 108c of the display panel 108
Is turned on, and a preparation display is performed (step 40).
5) Perform dial processing for connecting to the host device 131 (step 407). The detailed processing content of step 407 will be described later with reference to FIG.

When the dialing process is completed, the host device 1
It is confirmed whether or not the connection to the line 31 has succeeded (step 409). If the connection has succeeded, a connection procedure process for receiving approval from the host device 131 with the desired energization time is performed (step 409). Step 411). Step 41
The detailed processing contents of 1 will be described later with reference to FIG.

At the end of step 411, the communication with the host device 131 ends, and the line is disconnected.

Thereafter, it is confirmed whether or not the connection procedure processing has been completed normally (step 413). If the connection procedure processing has been completed normally, the power supply time approved by the host device 131 is stored and stored (step 415), and the display panel is displayed. 108 lights 10
8d is turned on to display the start of energization (step 417), and the circuit of the relay device 109 is closed to start energization (step 419).

Thereafter, a condition confirmation process for confirming whether or not the condition for terminating the energization is satisfied (step 4).
21) If the energization is not to be ended and the remaining time until the end of the energization has reached 15 seconds before (step 42)
3), a power-supply end notice is displayed (step 425). In step 425, specifically, the illumination 108e of the display panel 108 is flickered. The detailed processing content of step 421 will be described later with reference to FIG.

If the energization should be terminated (step 427), the circuit of the relay device 109 is opened to terminate the energization (step 429), and returns to the beginning of the energization control main processing (step 431). . In step 429, the illumination 108e of the display panel 108 is turned on to display the termination of energization.

Steps 423 and 42
If it is determined in step 7 that the remaining time until the end of energization is longer than 15 seconds, the process returns to step 421.

On the other hand, if it is determined in step 411 that the connection to the host device 131 has not been successful, and if it is determined in step 413 that the connection procedure processing has not been completed normally, the display panel 108 lighting 108f
Is turned on to display an error (step 43).
3) Return to the beginning of the energization control main process (step 43)
5).

Here, the outlet connection waiting process of step 401 will be described with reference to the process flowchart of FIG.

As shown in FIG. 5, in the outlet connection waiting process, first, the illumination 108a of the display panel 108 is turned on.
Is turned on to display an outlet connection waiting display (step 501), the plug insertion detection switch 114 is checked (step 503), and when it is determined that the plug insertion detection switch 114 is closed and there is an outlet connection (step 505). ), Illumination 108 of the display panel 108
After turning off “a” and deleting the outlet connection waiting display (step 507), the outlet connection waiting process ends.

If it is determined in step 505 that the plug insertion detection switch 114 is open and there is no outlet connection, the process returns to step 503 and repeats the determination.

Next, the energization desired time input wait processing of step 403 will be described with reference to the processing flowchart of FIG.

As shown in FIG. 6, in the process of waiting for input of a desired energization time, first, the illumination 108 of the display panel 108 is turned on.
After b is turned on to display the desired power supply time input waiting display (step 601), it is determined whether the 15-minute selection switch 115a or the 30-minute selection switch 116a has been pressed (step 603, step 609).

If the 15-minute selection switch 115a is pressed (step 603), the illuminated start switch
(1) Turn on the illumination portion 115b of 115 (step 6)
05), "15 minutes" is set in the "desired energization time" (step 607), and the energization desired time input waiting process ends.

If the 30-minute selection switch 116a) is pressed (step 609), the illuminating portion 116b of the illuminated start switch (2) 116 is turned on (step 611), and the "desired energization time" is set to "30". After setting "minute" (step 613), the process of waiting for input of a desired energization time is ended.

Next, the dial processing of step 407 will be described with reference to the processing flowchart of FIG.

As shown in FIG. 7, in the dialing process, first, it is determined whether “15 minutes” or “30 minutes” is set in “desired energization time” (step 701). If "15 minutes" is set, 15
The telephone number of the host device 131 for power distribution is acquired (step 703). If "30 minutes" is set, the telephone number of the host device 131 for energizing for 30 minutes is acquired (step 705).

In the first embodiment, the telephone number used for connecting to the host device 131 is different depending on the desired energization time. This is because charging is changed according to the energizing time. Note that one host device 131 may correspond to two types of telephone numbers.
In the embodiment, two types of host devices 131 corresponding to each of the two types of telephone numbers are provided for explanation. In addition, “desired energization time” is set in step 607 or step 6 of the energization desired time input wait process shown in FIG.
In 13, “15 minutes” or “30 minutes” is set.

Next, the modem 103 is controlled so as to transmit to the host device 131 using the obtained telephone number (step 707), and it is confirmed whether or not the line connection has been normally performed (step 709).

If the line connection has been made normally, "connection" is set in "line connection result" (step 71).
1) The dialing process ends. If the line connection has not been made normally, "connection error" is set in the "line connection result" (step 713), and the dialing process ends. Based on the “line connection result”, it is possible to confirm whether or not the line connection with the host device 131 has been successful in step 409 of FIG.

Next, the connection procedure processing in step 411 will be described with reference to the processing flowchart in FIG.

As shown in FIG. 8, in the connection procedure processing, first, an identification number obtained by encoding a management number uniquely assigned to the energization control device 101 and a value set in the “desired energization time” ("15 minutes" or "30 minutes") is converted into one data string and transmitted to the host device 131 (step 801). This data string is stored in the host device 13.
This is an energization authentication request for No. 1. Note that “desired energization time” is set to “15” in step 607 or step 613 of the energization desired time input wait process shown in FIG.
"Minute" or "30 minutes" is set.

Thereafter, a response to the energization authentication request is received from the host device 131 (step 803). In the data string of the response to the energization authentication request, as described later,
Contains "status" and "return value".

Then, the content of the response received from the host device 131 is determined (step 805), and if “normal response” is set in “status”, the host device set in “return value” The authenticated energization time is cut out and stored in the memory 131 (step 807), and a telephone line disconnection request is transmitted to the host device 131 (step 809).

Then, a response to the disconnection request is received from the host device 131 (step 811), and the contents are determined (step 813). The data string of the response to the disconnection request includes “status” as described later.

Therefore, if it is determined in step 813 that "normal response" is set in "status", the line is disconnected (step 815), and the connection procedure process is terminated.

Further, step 805 or step 81
If it is determined in step 3 that “normal response” is not set in “status”, it means that the connection procedure has ended abnormally, so that “abnormal end” is set in “connection procedure result”. (Step 823), the line is disconnected (step 815), and the connection procedure process ends. "Connection procedure result"
Thus, in step 413 of FIG. 4, it is possible to confirm whether or not the connection procedure processing has been completed normally.

Next, the condition confirmation processing of step 421 will be described with reference to the processing flowchart of FIG.

As shown in FIG. 9, in the condition confirmation processing, first, it is determined whether or not a plug has been inserted into the commercial power output unit 113 (step 901). It is determined that the termination is due to the intention, and after the “energization termination condition is satisfied” (step 91
1), the condition confirmation processing ends.

On the other hand, when the plug is inserted into the commercial power output unit 113, the remaining time until the end of energization is calculated, and if the remaining time is 0 second (step 903),
After the “energization termination condition is satisfied” (step 911),
The condition confirmation processing ends.

If the remaining time until the end of energization is not 0 seconds (step 903), it is determined whether or not it is 15 seconds or longer (step 905). "Condition not satisfied" (step 90
7), the condition confirmation processing ends. If the time is less than 15 seconds, the condition confirmation process is terminated after setting the “energization end time 15 seconds before” (step 909).

The “energization end condition satisfied”, “energization end condition not satisfied”, and “energization end time 15 seconds before” are used in the determination in steps 423, 425, and 427 of FIG.

The operation of the energization control device 101 has been described above.

Next, the operation of the host device 131 will be described.
This will be described with reference to the processing flowcharts of FIGS.

FIG. 10 is a processing flowchart of the host processing.

The host process is a process performed when the power of the host device 131 is turned on and the arithmetic unit 135 activates and executes a host program stored in the memory 137, as shown in FIG. First, in the host processing, first, the modem 133 and the memory 1
37 are initialized (step 1001), and host main processing for actually performing energization control is performed (step 10).
03).

In the first embodiment, there are two types of host main processing. One is a host main process for energizing for 15 minutes, and the other is a host main process for energizing for 30 minutes. As described above, in the first embodiment,
Since the host device 131 for energizing for 15 minutes and the host device 131 for energizing for 30 minutes are provided, in step 1003, only one of these two types of host main processes is performed.

First, the host main process for 15-minute energization will be described.

FIG. 11 is a processing flowchart of the host main processing for energizing for 15 minutes.

As shown in FIG. 11, in the host main process for energization for 15 minutes, first, an incoming call from the energization control device 101 is waited (step 1101).
A data string transmitted from the power supply control device 101 is obtained (step 1103).

Subsequently, the acquired data string is interpreted, and if the request is an energization approval request (step 1105), the identification number included in the data string is checked (step 110).
7) It is determined whether the request is an energization approval request from the normal (actually operating) energization control device 101 (step 1).
109).

If the request is an energization approval request from the normal energization control device 101, it is determined whether the desired energization time is 15 minutes (step 1111). After returning a response to the effect that the energization time of 15 minutes is approved (step 1113),
It returns to step 1103. In step 1113, the “status” is set to “normal”, and the “return value”
, A data string in which “talk time 15 minutes” is set is created and returned.

If it is determined in step 1105 that the request is not an energization approval request, and if it is a disconnection request (step 1115),
After returning a response to approve the disconnection (step 11
17), the line is disconnected (step 1119), and the process returns to the head of the host main process for energizing for 15 minutes (step 112).
1). In step 1117, in detail, a data string in which "status" is set to "normal" is created and returned.

On the other hand, if it is determined in step 1109 that the identification number of the normal energization control device 101 is abnormal, if it is determined in step 1111 that the desired energization time is not 15 minutes, a series of determinations in steps 1105 and 1115 are performed. If it is neither an energization authentication request nor a disconnection request,
Go to step 1119, disconnect the line,
The process returns to the top of the host main process for 5 minute energization (step 1121).

Next, the host main process for 30-minute energization will be described.

In the first embodiment, the charging method (collection of the power supply cost) is not particularly described. However, the host device 131 transmits the information for specifying the person to be charged to the energization control device 101. , It is possible to charge later. Specifically, before step 801 in FIG. 8, a process for acquiring information on a person to be charged is prepared, and information on the person to be charged is included in the data string of the energization authentication request transmitted in step 801. What should I do? As a method of billing, debit from the account using the credit card of the person to be billed,
For example, the transfer sheet may be sent to a person to be charged.

Further, in the first embodiment, the line is disconnected before the start of power supply to enable data communication using the public telephone 153 during power supply. The line may be disconnected,
In this way, the call can be charged as a charge, and the power supply cost can be easily collected. Further, as described above, it is also possible to add the power supply cost to the call charge and collect the call charge using the pay information providing service.

The arithmetic unit 105 and the memory 107 are connected by a bus 121. The arithmetic unit 105 is a memory 1
The operation of the energization control device 1501 is realized by executing the program stored in the storage unit 07.

[0138] The public telephone device 153 can perform voice communication and data communication based on a user operation. The public telephone device 153 has a function of charging a call charge. In the second embodiment, the public telephone device 153
Billing can be performed according to a billing instruction from the power supply control device 1501. This billing instruction is performed via the communication line 1502. Further, in the second embodiment, the public telephone device 153 is capable of notifying the energization control device 1501 of the charging balance, and this charging balance notification is performed via the communication line 1503.

The communication lines 1502 and 1503 are connected to the arithmetic unit 105.

The commercial power input unit 111 and the commercial power output unit 113 are connected to a switch of the relay device 109, and the commercial power input unit 111 and the commercial power output unit 113 are electrically connected by the control output 123 of the arithmetic unit 105. The connection / disconnection is made.

The display panel 108 displays operation guidance and displays the state of the energization control device 1501 according to the control of the arithmetic unit 105.

FIG. 16 shows a state of the display panel 108.

As shown in FIG. 16, the display panel 108 is provided with the illuminations 108a, 108d, and 108g together with the operation guidance of the energization control device 1501 of the second embodiment. In the example of FIG. 16, the lighting that is turned on is indicated by a black circle, and the lighting that is turned off is indicated by a white circle. As will be described later, control is performed so that the illumination corresponding to the operation guidance that is currently focused on is turned on.

The display panel 108 has a commercial power output unit 113 disposed thereon.

The plug insertion detection switch 114 is a switch that closes when an external device is plugged into the commercial power output unit 113, which is an outlet, and its signal is output to the arithmetic unit 105.

Hereinafter, the operation of energization control device 1501 will be described with reference to the processing flowchart of FIG.

FIG. 17 is a flowchart of the energization control process.

The energization control process is a process which is performed by the arithmetic unit 105 activating and executing the energization control program stored in the memory 107 when the power of the energization control device 1501 is turned on. As shown in the figure, in the energization control process, first, the display panel 108
After the lights 108a, 108d, and 108g are turned off and initialized (step 1701), the plug insertion detection switch 114 is checked, and when it is determined that the plug insertion detection switch 114 is open and there is no outlet connection (step 1703). ), Perform the following steps:

That is, energization control device 1501 acquires the charging balance of public telephone device 153, and determines whether there is a charging balance (step 1705). If there is no charge balance, the light 108g of the display panel 108 is turned on (step 1709). If there is a charge balance, the light 108a of the display panel 108 is turned on (step 17).
07), returning to step 1703.

In step 1705 and step 1713 to be described later, the power supply control device 1501
Is configured to make an inquiry about whether or not a balance corresponding to a commercial power supply cost required for one unit of the energizing time has been input to the public telephone device 153 with a predetermined energizing time as one unit. 153 is an energization control device 1
A reply to the inquiry from 501 is notified via a communication line 1503 as a charge balance notification.

On the other hand, if it is determined in step 1703 that the plug insertion detection switch 114 is closed and the outlet is connected, the following steps are performed.

That is, the energization control device 1501 first sets the illuminations 108a, 108d, 10
After turning off 8g (step 1711), the accounting balance of the public telephone device 153 is acquired, and the presence or absence of the accounting balance is determined (step 1713). If you have a billing balance,
By electrically connecting the commercial power input unit 111 and the commercial power output unit 113 with the control output 123 to the relay device 109, the commercial power is supplied to the commercial power output unit 113 and energization is started (step 1715). ).

Subsequently, the power supply control device 1501 turns on the illumination 108d of the display panel 108 (step 171).
7) A billing instruction is output to the public telephone device 153 (step 1719). In response to the charging instruction output in step 1719, the public telephone device 153 uses the amount of coins inserted by the user or the balance of the prepaid card inserted by the user to treat the power supply cost (1 unit) (Commercial power supply cost required for the current supply time).

Thereafter, the power supply control device 1501 waits for one unit of power supply time (step 172).
1) By the control output 123 to the relay device 109,
By electrically disconnecting the commercial power input unit 111 and the commercial power output unit 113, the supply of commercial power to the commercial power output unit 113 is stopped, and the energization is terminated (step 172).
3). Then, after the light 108d of the display panel 108 is turned off (step 1725), the process returns to step 1703.

If it is determined in step 1713 that there is no charge balance, the illumination 108g of the display panel 108 is turned on (step 1727), and then step 170
Return to 3.

The operation of energization control device 1501 has been described above.

Hereinafter, the operation of the power supply control device 1501 will be described based on the above-described processing flowchart.

First, when the power is turned on, the power supply control device 1501 turns off the lights 108a, 108d and 108g of the display panel 108 in step 1701 in FIG. Wait for the transition to (state).

That is, the power supply control device 1501
In Steps 1703 and 1705 of FIG. 7, before the plug is inserted, it is checked whether or not the user has already entered a charge, and the charge balance (commercial power supply cost balance required for one unit energization time) is in a state. When it comes
By step 1707, the illumination 1 of the display panel 108
08a is turned on to notify the user that the power can be supplied, and prompt the user to insert the plug. If there is no charge balance, the illumination 108g of the display panel 108 is turned on in step 1709 to notify the user that power cannot be supplied.

If the plug is not inserted into the commercial power supply output unit 113, steps 1703 and 17
05, a series of processes in step 1707, or a series of processes in steps 1703, 1705, and 1709 are repeated.

If the user inserts a plug into the commercial power supply output unit 113 during these repetitions, the fact is detected in step 1703 in FIG. 17, and the process proceeds to step 1711.

That is, the power supply control device 1501
7 After turning off the lights 108a, 108d and 108g of the display panel 108 in step 1711, it is checked in step 1713 whether or not there is a charge balance (balance for commercial power supply cost required for one unit of power-on time). . Here, there are three reasons for checking the charging balance. The first reason is that, during the repetition, depending on the timing at which the user inputs the charge and inserts the plug, step 1 is performed.
It is conceivable that the plug insertion is detected in step 1703 before it is determined that there is a charge balance in step 705, and this is to deal with it. The second reason is that even if the user inserts the plug without inputting a fee, the plug insertion is detected in step 1703, and this is to be dealt with. The third reason is that the commercial power supply cost required for one unit of power supply time is charged separately, so that continuous power supply requires the commercial power supply cost for the next one unit power supply time. This is because it is necessary to determine whether there is a balance.

If the power supply control device 1501 determines that there is a balance corresponding to the commercial power supply cost required for one unit of power supply time, it starts power supply in step 1715 of FIG. Step 161
7, the illumination 108d of the display panel 108 is turned on to notify the user that power is being supplied.

Subsequently, the power supply control device 1501
In step 1719, the charge corresponding to the commercial power supply cost required for one unit of energization time is paid by the public telephone device 153.
After that, the flow shifts to step 1721 to wait until the energization time for one unit has elapsed.

When the energization time for one unit has elapsed, the energization control device 1501 terminates the energization in step 1723 in FIG.
By turning off the illumination 108d of the display panel 108 and notifying the user that the energization has ended by 5 in step 5, the process returns to step 1703. At this time, if the plug is still inserted, step 1711 is performed again. As a result of the series of processes in step 1713 and step 1713, if there is a balance corresponding to the commercial power supply cost required for the next unit of energization time, steps 1715, 1717,
A series of processing of 719, step 1721, step 1723, and step 1725 is repeated. That is, while the user is receiving the power-on service, charging is performed on a pay-per-use basis.

If the power supply control device 1501 does not have the balance of the commercial power supply cost required for the next unit of power supply time even if the plug is still inserted,
The process proceeds to Step 1727 of Step 7, in which the illumination 108g of the display panel 108 is turned on to notify the user that power cannot be supplied.

On the other hand, if the user pulls out the plug while receiving the power-on service, the fact is detected in step 1703 in FIG. Energization control device 1
When it is determined in step 1703 that is performed for the first time after the user has unplugged the plug that the user has pulled out the plug, the process proceeds to step 1705, and as described above, the illumination 108a of the display panel 108
And one of the lights 108g is turned on.

If the user inserts the plug without charging a fee, the fact is detected in step 1703 in FIG. In this case, the energization control device 15
In step 0113, since it is determined in step 1713 that there is no charge balance, the flow advances to step 1727 to turn on the illumination 108g of the display panel 108 and notify the user that power cannot be supplied.

As described above, according to the energization control device 1501 of the second embodiment, the public telephone device 15
When the connection is made with the public telephone device 153, the negotiation is not performed with the host device 131, and the billing (collection of the power supply cost) method is performed.
It is possible to perform charging using the charging function of (1).

In the second embodiment, the communication control device 1501 and the public telephone device 153 are connected by the communication lines 1502 and 1503. However, the current control device 1501 and the public telephone device are connected. Any connection means may be used as long as communication can be performed with the 153. For example, the power supply control device 1501 and the public telephone device 153 may be connected by radio waves or infrared rays.

Further, in the first embodiment, the energization control device 1501 is adjacent to the public telephone device 153, but may be incorporated in the public telephone device 153. In this case, the commercial power output unit 11
3 must be operable from outside the public telephone device 153, and the display panel 108 should be shared with the display panel of the public telephone device 153 or be viewed from the outside. Need to be able to

By the way, in the above-described two embodiments, the device to be supplied with commercial power is described as a device owned by the user. For example, the public telephone device 153 is installed in a public telephone box. In this case, a device installed in a public telephone booth may be set as a target device.

More specifically, as shown in FIG. 18, the plug of air conditioner 1801 installed in a public telephone box is always connected to commercial power output unit 113 of power supply control device 101 (or power supply control device 1501). By inserting the 1802, it is possible to operate the air conditioner while the user is using the public telephone 153.

When the energization control device 1501 according to the second embodiment operates the air conditioner 1801, it is preferable that the public telephone device 153 is not charged. If billing is to be performed, it is preferable to allow the user to select whether or not to operate the air conditioner 1801.

[0175]

As described above, according to the power supply control device of the present invention, commercial power can be supplied to an external device such as a portable terminal based on negotiation with a host device. Further, from the viewpoint of the host device, since the power supply control device can be remotely controlled, the host device manages the maintenance operation status of the power supply control device,
It is possible to charge the user (for example, charge by debiting an account using a credit card or the like).

Further, since there is no charging mechanism on the power supply control device side, the trouble of collecting the fee is unnecessary, and the risk of theft or breakdown is small.

In particular, if the power supply control device of the present invention is connected to a public telephone device, a commercial power supply service can be constructed using a public telephone box or the like.
