<p>PURPOSE:To surely rotate a handling roller at appropriate timing for preventing overlapped feed by reciprocating members between a position pushed with a cam follower projecting from a cam hole and a moved position through energization released from pushing of the cam follower, and providing the transmitting members to inchingly rotate the handling roller in the counter feed direction through a one-way clutch. CONSTITUTION:Following to sending out of piled paper sheets on a tray 3, the tray 3 is elevated up to the position as shown with two dot chain line, hereat, a cam follower 21 falls in the cam hole 23a of a front partition wall 23, a working arm 20 is rotationally moved clockwise up to abutting against a stopper 3d, and hereby the cam follower 21 makes a V lever 17 rotationally move from the full line position to the two dot chain line position. Consequently, an oscillating lever 16 is rotationally moved clockwise, a clutch claw 15 inchingly rotates a one-way clutch gear 14, namely, a handling roller 8 clockwise, and the surface of handling roller 8 contacted with a feed belt 7 is changed into a new one. When the tray 3 is brought down to be replenished with paper and paper feeding is performed again, similar process to the above-stated is carried out.</p> |
