Document Type and Number:
WIPO Patent Application WO/2019/142417
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress power consumption due to a standing-by for reception from the outside. A power supply control circuit for controlling power supply in an electronic apparatus is provided with a power supply start-up switch, a reception unit, a rectifier, and a control circuit. The power supply start-up switch is a switch for starting up a supply of power. The reception unit receives electromagnetic waves. The rectifier rectifies the electromagnetic waves received by the reception unit and outputs a rectified signal. The power supply start-up switch is made conductive by means of the rectified signal. As the power supply start-up switch is made conductive, the control circuit starts operating in response to a supply of power.
