<p><P>PROBLEM TO BE SOLVED: To provide a feeder unit capable of positioning a sub frame to a predetermined position of a main frame in a predetermined accuracy even when a high torque is input, preventing loss of transmission efficiency or deterioration of durability, and facilitating an operation for mounting the sub frame to the main frame. <P>SOLUTION: A recessed housing part 100 is provided on a rear face 84 of a swing arm 26. A transmission gear unit 64 is housed in the housing part. The transmission gear unit 64 is constituted by a supporting frame 120, and three gears 115, 116, 117 pivoted by it. When a motor 36 rotates and a paper feeding roller 25 rotates in a paper feeding direction 91, two gears at an end out of three gears try to move to a deeper side of the housing part 100. Thereby, the supporting frame is pressed to the deeper side of the housing part 100, and so the transmission gear unit 64 is positioned within a predetermined accuracy at the housing part 100. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
