項1又は2記載の複写機の用紙反転装置。[Claims for Utility Model Registration] 1. A copying machine equipped with a paper positioning member that is provided on a conveyance path for carrying in and inverting paper on which an image has been transferred, and that positions the leading edge of the paper to be carried in at a position according to the paper size. In the paper reversing device of the machine, a fur brush is provided to transport the paper carried into the transport path until it contacts the paper positioning member, a cushion member is attached to the paper contacting portion of the paper positioning member, and the cushion member is A paper reversing device for a copying machine, characterized in that a film with a small friction coefficient is attached to the paper contact surface. 2. A roller, which is rotated by the paper conveyed through the conveyance path and whose rotation is continued for a while due to inertial force, is placed in the conveyance path for reversing the paper, and is perpendicular to the paper conveyance direction of the conveyance path. 2. The paper reversing device for a copying machine according to claim 1, wherein a plurality of paper reversing devices are provided at intervals in the paper width direction. 3. A driving means for moving a paper positioning member to transport the paper in the conveyance path, and a drive means for activating the drive means after a predetermined time elapses after the paper carried into the conveyance path reaches the paper positioning member. 3. A sheet reversing device for a copying machine according to claim 1, further comprising a control means for controlling the positioning member to move in the sheet conveyance direction.
