する給紙装置。 The roller includes a paper feed roller that feeds paper, and a separation roller that contacts the paper feed roller to prevent double feeding of paper, and the separation roller is rotatable around a separation roller shaft and the separation roller shaft. The separation roller shaft consists of a roller tube fitted into the roller tube, and a torque limiter for cutting off the transmission of torque from the separation roller shaft to the roller tube when a torque of a certain level or more is applied to the roller tube, and the separation roller shaft is A drive device rotatably attached to the tip of a swinging arm that can freely swing around a support shaft on the paper feeder main body and rotationally drives the separation roller shaft includes a first gear fixed to the paper feed roller shaft; A second gear is rotatably supported by the paper feeding device main body and meshes with the first gear, and a third gear is fixed to the separation roller shaft and meshes with the second gear in a freely meshing and disengaging manner. The support shaft of the arm is disposed on the rear side of the separation roller shaft in the paper feeding direction so that the gear rotation moment generated by the load of the torque limiter presses the roller tube against the paper feeding roller. paper equipment.
