真複写機。[Scope of Claim for Utility Model Registration] A scanner equipped with a light source and a mirror, located below the platen glass, and reciprocated in the main scanning direction guided by a guide means to perform main scanning during copying. In an electrophotographic copying machine, during main scanning, the image placed on the platen glass moves by itself in the sub-scanning direction perpendicular to the main scanning direction, starting from a home position determined at the edge of the platen glass. A sensor for detecting whether or not a document area of a document has been reached; a shutter means that runs alongside the sensor and covers a portion of the light source outside the document area; and a drive means for the sensor and the shutter means are provided on the scanner. An electrophotographic copying machine characterized by:
