<p><P>PROBLEM TO BE SOLVED: To obtain a structure by which a retard roller 22 is fitted to a device body so that it hardly comes off, and the retard roller 22 is easily attached to and detached from the device body. <P>SOLUTION: The retard roller 22 is rotatably supported to a rotation support shaft 50. An engaging claw 51 and a lever 54 swinging the engaging claw 51 are arranged at an end of the rotation support shaft 50. A retard roller holder 221 supported by the device body includes an engaged part 61a engaged with the engaging claw 51. Since the engaging claw 51 engages the engaged part 61a, the retard roller 22 supported to the rotation support shaft 50 hardly comes off, and the retard roller 22 can be easily attached to and detached from the device body by operating the lever 54. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
