ABSTRACT:
Image-forming apparatus comprising an original document table on which an original document can be placed, an optical scanning mechanism for optically scanning an original document placed on the original document table, a moving mechanism which can cause reciprocal movement of this optical scanning mechanism parallel to the original document table, a specification switch for specifying the size of an original document placed on the original document table, detection switches which detect the position in which the optical scanning mechanism has been halted after being moved by the moving mechanism, a transferring mechanism that compares a first distance between the halt position of the optical scanning mechanism detected by the detection switches and one edge portion, going in the direction of scanning, of an original document of a size specified by the specification switch and a second distance between the optical scanning mechanism's halt position and the other edge portion of the original document and which can transfer the optical scanning mechanism to the edge portion of the original document which corresponds to that of the first and second distances which has been found to be the shorter in this comparison, a photoreceptor which picks up light reflected from the document on the optical scanning mechanism which has been transferred to the original document's edge portion being caused to scan the original document by the moving mechanism and an image-forming mechanism by which an original document image picked up by the photoreceptor is reproduced on recording material.
