<p>PURPOSE:To simplify a mechanism and action in a drive system by arranging separately each motor relating to a paper feed unit arranged in a paper feed part of an image forming device, so that each paper feed unit can be independently driven. CONSTITUTION:In a driving gear 20 arranged in a side part of a paper feed unit 10, a motor 21 and a gear unit are used to perform driving relating to a paper feed roller unit, constituted of a undger roller 11 and a paper feed roller 12, and to a conveying roller unit 14. In the gear unit, between gears 25, 27 arranged relating to the paper feed roller unit and the conveying roller unit 14, an output gear 22 is arranged so that uniform drive force can be transmitted relating to both the units. In the driving gear 20, by decreasing a number of intermediate gears, even when using the small sized motor, a paper feed action can be accurately performed.</p> |
