<p>PURPOSE:To reduce noise and vibration in a sheet distributing/accommodating device of a copier or the like having a plurality of pin trays by arranging a buffer member, which interferes when an engaging part of the pin tray and an engaging part of a cam member are engaged with each other, in the vicinity of an engaging part of both engaging members. CONSTITUTION:A buffer member 18, which deforms in a restorable manner when it is pressed, is arranged inside of a cam member 15 in such a manner that the buffer member 18 touches the inside of a cylindrical member of the cam member 15 when no external force acts on it (18). When this cam member 15 is rotated in the arrow-marked direction, since a pin tray 11 is energized toward the cam member (15) side, a projected part 14 is caught in a long groove 16 of the cam member 15, the pin tray 11 is lifted up. As a result, the pin tray 11 rotates around a pivot and moves upward. On the contrary, when the cam member 15 us rotated in the reverse direction, the pin tray 11 is lowered down. When the projected part 14 is caught in the long groove 16, the projected part 14 is caught first by the buffer member 18, thereby deforming the buffer member 18, and then abuts on the long groove 16. Therefore, noise and vibration are reduced.</p> |
