Then, the authentication information is transferred from the electronic device 1 to the electronic payment processing unit 119, and the electronic payment processing unit 119 communicates with the electronic payment server using the authentication information (step S3). If the electronic payment server is not authenticated as a result of the communication (step S4: No), the processing of the electronic payment processing unit 119 returns to step S1, and if the electronic payment server is authenticated (step S4: Yes), the electronic payment processing is performed. The process of the unit 119 moves to step S5.

  In step S5, the electronic payment processing unit 119 requests the electronic payment server for purchaseable amount information as an amount that can be used in an account based on authentication information in the electronic payment server, for example. When the electronic payment processing unit 119 receives the purchaseable amount information, the electronic payment processing unit 119 transfers the purchaseable amount information to the control unit 120. Subsequently, the electronic payment processing unit 119 waits for purchase price information to be transferred from the control unit 120 (step S6: No).

  On the other hand, when the purchaseable amount information is transferred from the electronic payment processing unit 119 to the control unit 120 (step S21: Yes), the control unit 120 transfers the information of the product that can be purchased with the purchaseable amount to the product sales unit 124, The merchandise sales unit 124 is brought into a purchaseable state according to the purchaseable amount information (step S22). And the control part 120 waits for the notification of the completion of purchase from the goods sales part 124 (step S23: No).

  Subsequently, when the purchaser selects and presses the button corresponding to the purchase of power generation fuel in the product selection button unit 107, in step S25, the control unit 120 controls the pump drive unit 121 to operate the pump 111. The fuel in the fuel tank 110 is sucked into the pump 111, and the sucked fuel is sent to the fuel tank 6 of the electronic device 1 through the fuel supply connector 105 and the fuel introduction connector 5 by the pump 111. When a predetermined amount of fuel is fed, the control unit 120 stops the pump 111 via the pump driving unit 121. After supplying the fuel, the control unit 120 performs a water recovery process (step S26) and then returns to step S21.

  On the other hand, when the purchase price information is transferred from the control unit 120 to the electronic payment processing unit 119 (step S6: Yes), the electronic payment processing unit 119 transmits the purchase price information to the electronic payment server (step S7). The process of the unit 119 returns to step S1. As a result, the electronic payment is completed, and the purchase price is withdrawn from the account designated by the payment function of the electronic device 1. In addition, in the above, although the case where the fuel for electronic devices 1 was purchased by electronic settlement processing was explained, by inserting a coin or a bill into coin / banknote insertion part 108 of vending machine 100, for electronic device 1 The structure which purchases fuel may be sufficient.

Next, the water collection process of the control unit 120 will be described. FIG. 6 is a flowchart showing the flow of water recovery processing in the vending machine 100 of the present embodiment.
After fuel supply (step S25), the control unit 120 issues a command to the pump drive unit 122, and drives the pump 112 by the pump drive unit 122 (step S31). Water in the generated water tank 9 of the electronic device 1 is sent to the generated water recovery tank 114 by the pump 112. When all the water in the generated water tank 9 has been sent to the generated water recovery tank 114, the control unit 120 issues a command to the pump drive unit 122 to stop the pump 112. Here, the determination as to whether or not all the water in the generated water tank 9 has been sent to the generated water recovery tank 114 is performed by, for example, detecting the amount of water sent from the pump 112 and stored in the generated water recovery tank 114. When the increase in the amount of water in the generated water recovery tank 114 stops, it may be determined that all the water in the generated water tank 9 has been sent. Further, when the amount of water flowing in the flow path between the generated water discharge and injection connector 103 and the pump 112 is detected and the amount of water flowing in this flow path becomes zero, all the water in the generated water tank 9 is sent. You may make it judge that it was.

  Subsequently, the control unit 120 operates the control unit of the electronic device 1 through the USB connector 104 and the USB connector 4 to perform operations including the startup or startup of the fuel cell power generation unit 7 in the power supply system 200 of the electronic device 1 ( A water amount (water amount data Vn) required for the power generation operation) is requested. Upon receiving the request, the control unit of the electronic device 1 transmits the water amount data Vn to the control unit 120, and the control unit 120 receives the water amount data Vn. Thereby, the control part 120 reads the water quantity data Vn (step S32).

  Subsequently, the control unit 120 issues a command to the pump driving unit 123, and drives the pump 113 by the pump driving unit 123 (step S33). The water in the generated water recovery tank 114 is sent to the generated water tank 9 by the pump 113. Then, when water of only the water amount data Vn is sent to the generated water tank 9, the control unit 120 issues a command to the pump driving unit 123 to stop the pump 113. Then, the water recovery process ends.

  In addition, the process of step S32 may be performed before the process of step S31. Moreover, when the process of step S32 is performed before the process of step S31, when the water in the generated water tank 9 is being sent to the generated water recovery tank 114 by the pump 112, all of the generated water tank 9 When water becomes only the water amount data Vn, the control unit 120 may issue a command to the pump driving unit 122 to stop the pump 112. In this case, the control unit 120 ends the water recovery process without performing the process of step S33. Here, the determination as to whether or not only the water amount data Vn has been sent is determined, for example, that the water amount data Vn has been sent when the operation time of the pump 112 has reached a time sufficient to send the water amount data Vn. You may make it do. Further, when the amount of water flowing in the flow path between the generated water discharge / injection connector 103 and the pump 112 is detected and the integrated amount of water flowing in the flow path reaches the water volume data Vn, the water volume data Vn is sent. You may make it judge.

  As described above, according to the present embodiment, after all the water in the generated water tank 9 of the electronic device 1 is recovered in the generated water recovery tank 114, the fuel cell power generation unit 7 in the power supply system 200 of the electronic device 1 is used. Since the water of only the amount of water data Vn necessary for the operation including the start-up time is supplied to the generated water tank 9 of the electronic device 1, the water required for the operation including the start-up time of the fuel cell power generation unit 7 is generated in the generated water tank. 9 can be left. Further, by obtaining the water amount data Vn from the electronic device 1, it is possible to leave an appropriate amount of water corresponding to each electronic device.

  In the above, in order to leave only the amount of water Vn in the generated water tank 9 of the electronic device 1, after collecting all the water in the generated water tank 9, the water of the amount Vn is supplied to the generated water tank 9. For example, when the amount of water to be recovered from the generated water tank 9 in order to leave water of the water amount Vn in the generated water tank 9 can be obtained from the electronic device 1, the generated water tank 9 By sending only a recovered amount of water to the generated water recovery tank 114, water of the water amount Vn may be left in the generated water tank 9.

  Further, when the water level accumulated in the generated water recovery tank 114 reaches the connection portion with the pipe 115, the water in the generated water recovery tank 114 is discharged, so that the water accumulated in the generated water recovery tank 114 is discharged. Will not disappear. Therefore, the amount of water to be supplied to the electronic device 1 can be kept in the generated water recovery tank 114.

  Further, when the water level recovered in the generated water recovery tank 114 reaches the connection portion with the pipe 115, the water in the generated water recovery tank 114 is discharged to the pipe 115 and evaporated and evaporated in the evaporator 116. Therefore, it is not necessary to periodically collect the water in the generated water collection tank 114.

  The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.

  In the above embodiment, the evaporator 116 is dedicated for evaporating the water sent from the generated water recovery tank 114. For example, when the vending machine 100 has a refrigeration function, condensation occurs on the refrigeration unit.
