Abstract
A power supply control device is provided with a first power supply input terminal to which a power supply is provided and a second power supply input terminal to which a power supply is provided. A power supply input detection unit detects an instance when the input of the second power supply input terminal is above a predetermined value and then a switch unit cuts off power supplied from the first power supply input terminal and activates power supply from the second power supply input terminal when the input from the second power supply input terminal is above a predetermined value according to the power supply input detection unit. A power supply processor processes a power supply supplied by way of the first or second power supply input terminal.
