Abstract

An electrostatic copying apparatus has a copying paper wound in a roll-like form, and an endless drive cable loop is wrapped about two drive reels rotated in one direction so as to cause part of an optical device or an original document carrier to travel reciprocally during a copying operation. Each copying operation mode, such as copying paper feeding, exposure, and copying paper cutting, is timed by means of mechanical constructions including a moving member to cause a paper feed detecting member, an exposure detecting member, a paper cut detecting member and a de-energization detecting member to pivot. These pivot motions result into a paper feed linkage actuation of a paper feed device, an exposure linkage energization of an exposure lamp, and a paper cut linkage actuation of a paper cut device.
