求項１に記載のコロ搬送装置。[Claims for Utility Model Registration] (1) A pair of shafts consisting of a drive shaft whose both ends are pivotally supported by a side plate and a driven shaft whose both ends are applied with a pressing force in the direction toward the drive shaft. In a roller conveyance device, which consists of a plurality of rollers with the same diameter installed at the same position on each axis, and which conveys the paper by pressing the roller groups of both axes together and holding the paper between them, the axes of each of the above rollers are 1. A roller conveyance device characterized in that the length in the direction decreases from the center toward both ends so that the pressing force between each pair of rollers is approximately the same. (2) According to claim 1, the length of each roller in the axial direction is made shorter from the center toward both ends, thereby reducing the difference in the pressing force between the center and both ends. The roller conveyor device described.
