<p>PURPOSE:To easily perform jam processing by automatically releasing the pressurization of the roller of a lower unit and a guide plate in conjunction with the slide of an upper unit when a jam occurs. CONSTITUTION:An idle roller 226 pressed to a roller 225 is fitted to the long hole of a moving side paper guide 207, and it is excited to the roller 225 side by a spring 227. A roller 229 is pivotally supported on the moving side paper guide 207, and it is pressed in the arrow P direction by a plate spring 230 provided on an upper unit 3. When a sheet S3 is jammed, the upper unit 3 is slid in the drawing direction, and the moving side paper guide 207 is rotated to the chain line position in the arrow 231 direction. The pressurization of the moving side paper guide 207 is naturally released, and jam processing can be easily performed.</p> |
