1. A power supply startup system comprising:
- a battery;
a device supplied with a power from the battery; and
a controller which performs a wireless communication with the device and is separately provided with the device,wherein the device has a power supply section which serves as a power supply by using the power supplied 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 has two signal regions of a first stage and a second stage which is different from the first stage,the startup section outputs a first startup signal to the power supply section when the startup section receives the wireless startup signal of the first stage,the power supply section, to which the first startup signal has been input, starts supply of a first power to the startup section,the startup section supplied with the first power outputs a second startup signal to the power supply section when said startup section receives the wireless startup signal of the second stage, andthe power supply section, to which the second startup signal has been input, starts supply of a second power different from the first power to the control section, and the control section starts power supply to the power supply section, the startup section, and the wireless communication section and starts control of operation of the power supply section, the startup section, and the wireless communication section.

Abstract
A power supply startup system 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.
