Abstract

PURPOSE:To prevent the neglection in switching-off of an electric power source by comparing the light detected in the outside and the input state with a power switch and producing an alarm sound in a copying machine or the like. CONSTITUTION:The state detection signal of a door switch DWS is applied to a CPU3, and when the DWS is off, the on and off of a main switch MSW is decided. When it is on, the input decision of an external light sensor 2-1 is accomplished. The detection signal of the sensor 2-1 is fed to a CPU3 after A/D conversion 2-3, by which it is compared with a reference value, and when it is low brightness, a signal for emitting an alarm is supplied to a voice synthesizing LSI4.
