Claims

[Claims for Utility Model Registration] (1) The paper taken out from the paper storage device is temporarily stopped in front of the image forming area to position the paper, and a loop is formed at the leading edge of the paper to record the paper. In an image forming apparatus configured to send information to an image forming section in synchronization with the timing, a means for controlling feeding force is provided in a conveyance roller device disposed upstream of a registration gate, and A paper conveyance device characterized by pressing the paper against a registration gate with a constant pressure while forming a loop. (2) The paper being carried out from the paper storage device is temporarily stopped in front of the image forming area to position the paper, and a loop is formed at the leading edge of the paper to form an image in accordance with the recorded information. In an image forming apparatus configured to feed paper toward a paper sheet, a swingable buffle is provided on a guide plate downstream of a conveyance roller device disposed upstream of a registration gate, and a 1. A paper conveyance device, characterized in that the buffle is oscillated by a loop in which the buffle is oscillated, and a driving means of a conveyance roller device is controlled based on information about the oscillation of the buffle. (3) In the downstream part of the conveyance roller device, the buttful arranged on the guide plate is divided into multiple parts in the width direction of the paper conveyance path, and only the buttfull on the register side is shaken. 3. The paper conveyance apparatus according to claim 2, further comprising a motion detection means, and is configured to control the drive of the conveyance roller device based on the information on the vibration of the buttful. (4) At the downstream part of the transport roller device, the buttful arranged on the guide plate is divided into a plurality of parts in the width direction of the paper transport path, and all the buffles are provided with rocking detection means, and 3. The paper conveying device according to claim 2, wherein the sheet conveying device is configured such that the driving of the conveying roller device can be controlled based on information about the swinging of the sheet conveying device.
