PURPOSE:To miniaturize a device, by selectively driving each paper feed roller of paper feed parts in two places with a single motor and eliminating the necessity for using a clutch with complicated mechanism. CONSTITUTION:A motor 12 is rotated forward, if a worm 13 and worm wheel 15 are rotated to a direction A as shown by a full line, a driving gear 16 is rotated forward through an intermediate gear 14 as shown by a full line arrow head A. Accordingly, a one-way clutch 19 is operated to rotate a paper feed roller shaft 5a and perform a paper feed. While an intermediate gear 18 and driving gear 17 are reversely rotated, and a one-way clutch 20 is operated, accordingly, a paper feed roller 105a is not rotated. Similarly if the motor 12 is reversely rotated, the paper feed roller shaft 105a is operated and the paper feed roller 5a is stopped. In this way, only a single set of the motor 12 is required, and miniaturization can be performed. |
