Provided is an apparatus or system which activates a power supply of a device provided with a battery or the like at high speed by a wireless signal while suppressing current consumption on standby. The power supply startup system includes a battery, a device supplied with a power from the battery, and a controller which performs wireless communication with the device. The device includes a power supply section which generates a power supply from the battery, a startup section which receives a wireless startup signal transmitted by the controller and outputs a startup signal to the power supply section, a control section which controls the power supply section and the startup section, and a wireless communication section which performs wireless communication with the controller. The wireless startup signal includes at least two signal regions of a first stage and a second stage. When receiving the first stage of the wireless startup signal, the startup section outputs a first startup signal to the power supply section. The power supply section, to which the first startup signal has been input, supplies a first power to the startup section. When receiving the second stage of the wireless startup signal, the startup section supplied with the first power outputs a second startup signal to the power supply section. The power supply section, to which the second startup signal has been input, supplies a second power to the control section. The control section controls power supply to the power supply section, the startup section, and the wireless communication section and operation thereof. |
