囲第1項記載の用紙先端位置決め装置。[Scope of Claim for Utility Model Registration] (1) A paper transport path for transporting paper from a paper feed device provided corresponding to a paper storage member such as a paper feed cassette toward an image transfer section of a photoreceptor drum. In a copying machine configured to send out a leading edge of a sheet of paper at a timing consistent with a toner image formed on a photoreceptor drum, a registration roller provided at a position in front of the photoreceptor drum; It is composed of a registration gate provided nearby, and a conveyance roller provided on the paper feeder side at a predetermined distance from the registration roller, and a feed sensor is provided corresponding to the registration gate, and a feed sensor is provided in front of the feed sensor. A paper leading edge positioning device characterized in that a paper thickness detection sensor is provided at a position. (2) The copying machine is provided with a control device that inputs the signals obtained by the feed sensor and the paper thickness detection sensor, and the control device inputs the information on the paper thickness detected by the paper thickness detection sensor. Therefore, there is a request for utility model registration, which is characterized in that the driving time of the conveying roller is set after the leading edge of the paper is detected by a feed sensor, and the size of the loop can be changed depending on the paper quality. The paper leading edge positioning device according to scope 1.
