IPC: B65H31/20
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To stably receive a sheet even if the size of the sheet is a little different by providing a pair of upper trays being moved in the horizontal direction, letting sheets line up, and letting a sheet downward, and a lower tray loading the fallen sheet from the upper tray thereon. SOLUTION: For loading a sheet on a lower tray 34, upper motors 35 are driven in the opposite directions (i.e., A and B directions) to move upper trays 33 opposite to each other. Namely, the left side upper motor is driven in the B-direction to move the left side upper tray in the D-direction, and the right side upper motor is driven in the A-direction to move the right side upper tray in the C-direction. Accompanying this, the distance between the two upper trays 33 becomes wide to let fall a sheet received in the trays. At this time, the fallen sheet is loaded on the lower tray 34. In this way because the two upper trays are moved in the horizontal direction to form a space capable of receiving the sheet, various sheets can be received.
