したことを特徴とする複写機。 In a copying machine that transfers an image of a document positioned with respect to one side edge of a platen along the moving direction of a photoreceptor and a reference edge of the platen adjacent thereto onto copy paper supplied at a predetermined timing. , a positioning member provided on one side edge of the platen along the direction of movement of the photoreceptor; and a positioning member provided under the platen near the positioning member and moving along the length of the positioning member before the exposure operation. a member, a sensor provided on the movable member to detect the edge position of the document, and a determining means that uses the sensor output as an input signal and determines an offset amount between the reference edge of the platen and the document edge; and a delay means for delaying the supply timing of the copy paper by a time corresponding to the offset amount determined by the determination means, the image transfer timing of the document positioned only with respect to the positioning member and the supply timing of the copy paper. A copying machine characterized by being made to match.
