PURPOSE:To save the space of a device and perform its miniaturization, in the above described device of a picture forming equipment equipped with plural sheet feed parts, by selectively performing a sheet feed from the plural sheet feed parts through a single driving source. CONSTITUTION:At feed operation of a sheet, a motor 1 is rotated to the direction of an arrow head A, if a gear 3 is rotated clockwise through a worm gear 2, a feed roller 7 is rotated to the same direction through a rotary shaft 7a by a one-way clutch 4, and the sheet contacted to said roller is fed. At this time, since a spur gear 5, meshed to a spur gear 3b of the gear 3, is rotated counter clockwise, driving power is not transmitted to a rotary shaft 8a through a one- way clutch 6, and a sheet 12 is not fed by a feed roller 8. On the contrary, if the motor 1 is reversely rotated to the above, the feed roller 7 is not rotated by the reverse action to the above, and only the feed roller 8 is rotated to feed the sheet contacted to this roller 8. |
