摘要： An electronic device includes a hold circuit and a microcomputer. The hold circuit is connected to a power control line from a control device. The microcomputer starts measuring the time of a second state when the power control line transitions from a first state to the second state due to the control device. The microcomputer controls a power supply circuit to turn on power when the second state continues for a first predetermined time, and operates the hold circuit to maintain the power control line in the second state for a second predetermined time after the first predetermined time has elapsed.
