構成したことを特徴とするカツト紙搬送装置。[Claims for Utility Model Registration] A means for temporarily stopping the paper is provided in a paper transport path provided between a paper feeding means that feeds paper one by one from a paper storage device and an image forming means such as a photoreceptor, In an apparatus configured to feed and transfer paper in accordance with an image, the paper transport speed by the transport roller device in the paper transport path between the paper feeder and the temporary stop means is controlled by the paper transport speed at the image transfer section. In addition, the paper transport speed in the image transfer section is set to correspond to the rotation speed of the photoreceptor, so that the transport roller device disposed in the paper transport path can release the nip state with respect to the paper. The present invention is characterized by providing a means for doing so, and configured to release the sheet conveyance action by the conveyance roller device in the paper conveyance path when the paper is conveyed by the conveyance roller devices in the front and rear portions of the temporary stop means. Cut paper transport device.
