<p>PURPOSE:To set the interval of paper feeding as well as to carry out the delivery of the motive power and the racing of a paper feeding roller following the movement of a motive power transmitter, so as to realize a high reliability of paper feeding and conveying operation, by providing cam means to a motive power input member, a motive power transmitter, and a motive power output member, respectively. CONSTITUTION:When a motive power input member 10 is driven to rotate, a motive power transmitter 20 moves to a motive power output member 30 side by the sliding of a projection 13 and the tapered surface 21c of an engaging groove 21, and a locking claw 22 and a rachet groove 31 are engaged. And the projection 13 is abutted to a drive transmitting surface 21a, so as to transmit the motive power to the motive power transmitter 20. As a result, the motive power is transmitted also to the motive power output member 30 through the motive power transmitter 20. On the other hand, when the motive power output member 30 is raced pulled by paper sheets, the engagement of the ratchet groove 31 and the locking claw 22 is released, and the tapered part of the locking claw 22 rides on the end face of the motive power output member 30, so as to move the motive power transmitter 20 to the right side. As a result, the motive power is not transmitted to the motive power output member 30.</p> |
