Abstract
An electrostatic copying apparatus of the type in which an original to be copied is scanned and exposed to light by moving one of an original-support having a transparent plate for placing the original thereon and an optical system relative to the other, and paper feed rollers are rotated in regard to the movement of one of the original-supports and the optical system thereby supplying a copying paper, and a drive mechanism for reciprocating one of the original-supports and the optical system has a driven wheel and an idle wheel rotatably disposed in a spaced-apart relation to each other and a winding power transmission system wound about these wheels and drivingly connected to one of the original-supports and the optical system; wherein a synchronizing wheel is rotatably disposed adjacent to, and coaxially with, one of the driven wheel and the idle wheel of the drive mechanism, an engaging protrusion is fixed to the winding power transmission system, a plurality of engaging portions capable of cooperating with the engaging protrusion are formed on the peripheral edge portion of the synchronizing wheel, and the paper feed rollers are fixed to a support shaft mounted rotatably and drivingly connected to the synchronizing wheel whereby when the drive mechanism is operated to move the winding power transmission system, the engaging protrusion engages with one of the plurality of engaging portions to rotate the synchronizing wheel and thus rotating the paper feed rollers.
