<p><P>PROBLEM TO BE SOLVED: To accomplish miniaturization of a paper feed tray of two-stage system focusing attention on a hinge mechanism. <P>SOLUTION: An opening/closing shaft part 371 is provided on a support member 361, a first bearing part 376 and a second bearing part 377 slidably in contact with an outer peripheral surface of the opening/closing shaft part 371 are provided on a second paper feed tray body 380, and a removal-stop member 378 is provided at a distal end side of the second bearing part 377. A diameter dimension of a small diameter part 372 in contact with the first bearing part 376 is made smaller than a diameter dimension R2 of a large diameter part 373 in contact with the second bearing part 377, and an axis of the small diameter part 372 and an axis of the large diameter part 373 are positioned on a coaxial line. Thereby, miniaturization of the paper feed tray of two-stage system can be accomplished by miniaturizing the hinge mechanism 370, and the second paper feed tray body 380 can be certainly prevented from being removed from the support member 361. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
