搬送装置。[Claims for Utility Model Registration] 1. The position of the leading edge of the paper is determined by sandwiching and transporting the paper by a plurality of paper transporting means and abutting the leading edge of the paper against a positioning member provided in the paper transporting path. In a sheet conveying device that performs alignment, when the leading edge of the sheet approaches the positioning member, the clamping state of the remaining sheet conveying means excluding one sheet conveying means among the plurality of sheet conveying means is released. A paper conveying device characterized by being provided with a mechanism. 2. The paper conveying device according to claim 1, wherein the operation of the positioning member is controlled in conjunction with the operation of a mechanism for releasing the pinched state of the remaining paper conveying means. 3. The paper transport device according to claim 1, wherein the plurality of paper transport means are a plurality of transport roller pairs. 4. The paper transport device according to claim 1, wherein the plurality of paper transport means are a transport roller pair and a paper feed roller. 5. The paper conveyance device according to claim 1, wherein the positioning member is a registration gate provided so as to be movable forward and backward with respect to the paper conveyance path. 6. The paper conveyance system according to claim 1, wherein the positioning member is a registration roller pair consisting of a drive roller whose rotation is controlled in synchronization with the conveyance of the paper and a pinch roller that is in pressure contact with the drive roller. Device.
