Abstract
An electronic device has: an operation unit; a power supply unit; an input changeover switch; and a controller. The power supply unit is supplied commercial power and supplies the operating power to the operation unit. The input changeover switch switches between supplying or not supplying the commercial power to the power supply unit. The controller controls the input changeover switch. The controller includes: a power input portion; a control signal input portion; and a switching signal output portion. When the device power is being supplied from a master electronic device to the power input portion and the control signal from the master electronic device is received by the control signal input portion, the switching signal output portion outputs to the input changeover switch a signal instructing to switch and supply the commercial power to the power supply unit.
