<p>PURPOSE:To permit a motor to attain its small capacity by urging a loading bed in the rising direction and connecting a feed means and a lift means to a normally and reversely rotatably motor respectively through one-way power transmitting means in a reverse direction to each other, in the case of a large number of sheets-paper feeder connected to an electronic copying machine or the like. CONSTITUTION:Mounting a one-way clutch 92 interposing and a pulley 93 to a shaft 89 of feed rollers 90, 91, a timing belt 94 is linked between a pulley 86 and the pulley 93. This pulley 86 performs power transmission by a belt between a pulley 85 coaxial with the pulley 86 and a pulley 83 coaxial with a motor 82. Accordingly, the rollers 90, 91 rotate only when the motor 82 rotates in one direction, feeding a paper sheet. And mounting a one-way clutch 97 to a shaft 96 being associated with the lift means of a loading bed, it is driven by driving the lift means only when the motor 82 rotates in the other direction. Further a loading bed not shown in always urged to the upper by a spring. By this constitution, the motor is formed in small side.</p> |
