うにしている。Further, as shown in FIGS. 8 and 9, when the U-shaped base side tray 1 and the plurality of U-shaped auxiliary trays 2, 3 and 4 are opened horizontally, the upper surfaces of the trays are in the sheet feeding direction. Each pivot position is set so as to obtain a substantially horizontal state without a step. Further, the U-shaped base side bases 2g, 3g, 4g of the auxiliary trays 2, 3, 4 come into contact with the protrusions 1e, 2e, 3e of the trays 1, 2, 3 due to the difference in distance from the pins. Thus, the trays 1, 2, 3, 4 are kept in a horizontal state when the trays 1, 2, 3, 4 are opened by blocking the rotation by the pivotal portion.

の低減を図ることができる効果がある。According to the present invention, since the auxiliary trays on the front end side can be folded or opened inside the U-shape of the trays in the order in which the auxiliary trays on the front end side are sequentially arranged, the storage and opening operations of the trays can be smoothly performed. In addition, when the U-shaped base side tray and the plurality of U-shaped auxiliary trays are opened horizontally, the upper surface of each tray has a substantially horizontal state in which there is no step in the paper feeding and discharging direction. Therefore, the paper moves smoothly on the tray without being scratched by the step, and the pulling-in operation at the time of feeding and the discharging operation at the time of discharging are not hindered. In addition, when the auxiliary trays are sequentially held in a state of being warped upward from the leading end side, the pulling operation at the time of feeding can be made smoother, and since each tray is U-shaped, the tray area can be reduced. There is an effect that the material cost can be reduced.
