ABSTRACT:
The output interval between a signal for shifting a communication node from a sleep state to a wake-up state and a signal for operating an electrical component is set to be longer than the wake-up rise time of the communication node. After the communication node is reliably shifted to the wake-up state, an operation signal can be transmitted to the electrical component, and an unnecessary dark current can be prevented from being supplied to the communication node in the wake-up state.
