<p>PURPOSE:To perform intermittent control of a one-way clutch without using a solenoid, which one-way clutch transmits driving forces to an introduction roller. CONSTITUTION:A stopper member 12 having an abutting portion 12a which is made to abut on the protrusion 12a of a one-way clutch 12 is rotatably provided and connected via a spring clutch 30 to a driving gear 24 which is driven by a driving motor 21 used for driving an introduction roller 6 and capable of normal and reverse rotations. Prior to feeding of paper the driving motor is reversely rotated and thereby the abutting portion 12a of the stopper member 12 is disconnected from the protrusion 12a, and then paper is fed by means of the normal rotation of the driving motor and also the abutting portion of the stopper member is made to abut on the protrusion 12a so that the introduction roller is stopped.</p> |
