<P>PROBLEM TO BE SOLVED: To stably feed a recording sheet, in an image forming device transmitting a driving force to a feeding roller supported to one end side of a swingable holding member through a planetary gear mechanism and feeding the recording sheet placed on a placing surface of a tray. <P>SOLUTION: When a sun gear 81 is rotated in a counterclockwise direction, a planetary gear 82 is also swingingly moved in the same direction, and meshed with an input gear 89 rotatably mounted to a support shaft 28 of a sheet supply arm 26 (A). The rotation of the input gear 89 is transmitted to a sheet supply roller 25 through a toothed pulley 91, a belt 93, and a toothed pulley 92. Since a planetary gear mechanism 80 and a drive shaft 81A thereof are provided independently from the support shaft 28 as the swinging center of the sheet supply arm 26, a power transmission state relative to the sheet supply roller 25 is prevented from being distorted. Accordingly, the occurrence of skewing during the feeding of the recording sheet 50 is prevented, and the feeding of the recording sheet 50 can be stably executed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
