Claims

[Claims for Utility Model Registration] 1. A reversing roller that constantly rotates in a predetermined paper conveyance direction, an opposing roller rotatably provided in opposing contact with the reversing roller, and a common tangential plane of these pair of rollers. a feeding path extending toward the paper feeding side due to the rotation of these rollers, and a direction forming an acute angle with the feeding path after passing through a part of the circumferential surface along the rotational direction of the reversing roller from the common contact portion of the pair of rollers. A reversing device having a turning path extending to the turning path, a sheet reverse feeding means provided on the turning path, and a branching pawl swingably provided at the exit portion of the pair of rollers, the branching pawl being It has three surfaces: a curved surface portion shaped to follow the circumferential surface of the reversing roller, a belly surface portion shaped to follow the above-mentioned delivery path, and a back surface portion shaped to follow the above-mentioned turning path, and at least the paper introduction portion of the curved surface portion is When the back surface portion faces each of the turning paths, the ventral surface portion intersects with the delivery path, and when the ventral surface portion faces the delivery path, the curved surface portion crosses the delivery path. A paper reversing device characterized in that the swinging position of the branching pawl is set so that the back surface portion intersects with the turning path. 2. In claim 1, the reversing roller is constituted by a corrugated roller, a branch claw is provided between each roller constituting the corrugated roller, an elastic plate is attached to the back surface, and the free end of the elastic plate is connected to the roller. A paper reversing device characterized in that the paper reversing device is located inside the outer peripheral surface of the paper. 3. In claim 1, the reversing roller is constituted by a corrugated roller, and branching claws are provided between each roller constituting the corrugated roller, and as the shape of the curved surface portion advances in the rotation direction of the roller, the outer periphery of the roller changes. A paper reversing device characterized by being formed so as to bite inward from a surface.
