Abstract
Copying apparatus including a processing unit for forming a visible image on a copy material, a process control device for operatively controlling the processing unit, and a manual power switch unit for supplying power to electric loads of the processing unit and the process control device. The manual power switch unit includes an actuator to maintain an On condition during the time from the beginning of manual turning on, to the activation of manual turning off, and a coil to release the On condition of the actuator before the activation of the manual turning off. The power switch unit further includes a power control device for driving the coil to release the actuator from the On condition to the Off condition after a predetermined time has elapsed since a completion of copying operations, wherein the power control includes a timer controlled by the process control device for driving the coil.
