ABSTRACT:
An overlapped transfer-preventing mechanism that is inexpensive, simple in construction, requires no actuator and has a high degree of freedom of layout. The mechanism includes an upper, rotatably driven, separating roll and a pivot integrated with a lower separating roll. The pivot is provided with a one-way clutch which prevents rotation of the pivot in a paper-supplying direction but which permits rotation of the pivot in the direction opposite the paper-supplying direction. The one-way clutch has mounted on it a lever member, which is engaged with a paper-carrying plate by an upward or downward moving operation of the paper-carrying plate so as to rotate the one-way clutch in the direction opposite the paper-supplying direction.
