<P>PROBLEM TO BE SOLVED: To position an opening/closing part in an axial direction while restraining the turning of the opening/closing part. <P>SOLUTION: A dynamic vibration reducing means 120 has shafts 122a and 122b respectively provided on both end sides in the axial direction of a spindle 100 with respect to a double-sided unit 98, and holding members 124a and 124b fixed in an image forming apparatus main body 12 and respectively holding the shafts 122a and 122b. Slots 126 extended in the radial direction of rotation are respectively provided on both side surfaces of the double-sided unit 98, and the shafts 122a and 122b are moved in the radial direction of rotation of the double-sided unit 98. The width A of the holding member 124a in the axial direction of the spindle 100 is made larger than the width B of the holding member 12 in the axial direction of the spindle 100, and force to hold the shaft 122a by the holding member 124a is made stronger than force to hold the shaft 122b by the holding member 124b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
