Abstract

PURPOSE:To make constitution simple and facilitate maintenance and adjustment by letting operation check of copying process operations be executed through utilization of a timing signal generator for execution of copying process. CONSTITUTION:To scan and expose the image of the original on an original platen 14 to the surface of a rotating drum 11, a scanning mirror 15, lighting lamp 16 and scanning mirror 17 are reciprocated, whereby scanning is accomplished. In the constitution of performing timing controlling of image forming cycles by providing a regist sensor RG in the moving route of this reciprocating optical system and detecting moving positions, the timings are so controlled that when the detecting means makes detection operation upon moving of the optical system in one direction the timing controlling of the copying process operation is effected and when the detection operation is done upon moving to the other direction the check of the copying operation process is executed.
