- the power supply control unit 5 supplies power from the power supply unit 1 to the control unit 4.
- the control unit 4 supplied with the power may drive the display device 8 so that the user can determine that the power is supplied to the control unit 4.
- control unit 4 confirms that the communication unit 6 and the counterpart device 7 are communicable, and then turns on the power switch 3 during a period in which the communication unit 6 and the counterpart device 7 are communicable. Continue to the first state. Thereby, even if the user switches the start switch 2 to the second state, the power from the power supply unit 1 continues to be supplied to the control unit 4.
- the power supply control unit 5 continues to supply power from the power supply unit 1 to the sensor unit 9 while the power switch 3 is in the first state. While the power switch 3 is in the second state, the power from the power supply unit 1 is not supplied to the sensor unit 9. As a result, power is not supplied to the sensor unit 9 during useless periods, so that the power consumption of the power supply control device can be reduced.
- control unit 4 may use the display device 8 so that the user can identify that the power switch 3 is in the first state.
- control unit 4 transmits the data detected by the sensor unit 9 from the communication unit 6 to the counterpart device 7, and when the transmission to the counterpart device 7 is completed, the state of the power switch 3 is switched to the second state. Thereby, it is possible to avoid unnecessary power consumption of the power supply control device 1004.
- connection refers to being electrically connected, and includes not only a DC connection state but also an electromagnetic connection state. Yes.
- the power supply control device does not malfunction even if the start switch malfunctions, and the power supply unit is not consumed unnecessarily, so that it is possible to prevent unnecessary consumption of the battery and to drive a battery such as a small temperature sensor device or biological sensor device. It can be used for small electronic devices.
