Abstract:
According to one embodiment, a paper feeding device includes a paper feeding roller and a separation roller. The paper feeding roller and the separation roller are arranged in a parallel direction. The paper feeding roller and the separation roller interpose a sheet. The paper feeding device includes a paper feeding roller, a separation roller, a shaft, a holder, and a rotation stopping portion. The paper feeding roller is configured to convey the sheet in a conveyance direction. The separation roller is configured to be pressed against the paper feeding roller. The shaft is configured to rotatably support the separation roller via a torque limiter. The holder is configured to include a supporting portion. The supporting portion is provided with a first guide surface and a second guide surface facing each other and extending in the parallel direction. The rotation stopping portion is configured to be attached to the shaft. The rotation stopping portion is configured to be inserted between the first guide surface and the second guide surface. The rotation stopping portion is configured to include a first sliding surface and a second sliding surface. The first sliding surface faces the first guide surface on the paper feeding roller side of the parallel direction and a downstream side of the conveyance direction with respect to a rotation axis of the separation roller. The second sliding surface faces the second guide surface on an opposite side of the paper feeding roller of the parallel direction and an upstream side of the conveyance direction with respect to the rotation axis of the separation roller.
