PURPOSE:To improve operability by setting up time required from the end of device operation up to a power saving sate to a value longer than the suspending time of the device, and in a using environment having a short suspending time of the device, setting up the time from the end of the operation up to the power saving state to a shorter value. CONSTITUTION:An automatic power saving circuit is constituted of a common bus 1, a CPU 2, a ROM 3, a RAM 4, an input port 5, an output port 6, a clock 7, a switch 8 for starting device operation, a power saving relay 9, and a load 10 for turning off a power supply at the time of power saving. Since the time required from the end of the device operation up to the power saving state is set up to a value longer than the suspending time of the device, a user rarely meets the power saving state at the time of requiring the use of the device. In the using environment shortening the suspending time of the device, the time required up to the power saving state after the end of operation is shortened. Thus, the operability can be improved. |
