<p>PURPOSE:To carry out a stable paper feeding by preventing generation of a position slippage of a roller, as well as providing a simple structure in which a paper feeding roller can be installed and removed easily. CONSTITUTION:This paper sheet conveying structure consists of paper feeding rollers 23, bearings 40, holders 111a and 113a, and regulating pieces 421 and 422. The rollers 23 are fixed integrally at the center, and a peripheral groove 39a is formed near the end of a rotary shaft 39 to which bearings 40 are inserted to both ends. The bearings 40 and 40' of the rotary shaft 39 are journalled in the loading condition with the pair of holders 111a and 113a provided to the side plates 111 and 112 of a device main body. The movement of the bearing 40 in the axial direction is regulated by a regulating piece 421 abutting to the peripheral surface of the bearing 40, and the movement of the rotary shaft 39 in the axial direction is regulated by a regulating piece 422 extending from the device main body and fitting to the peripheral groove 39a of the rotary shaft 39.</p> |
