PURPOSE:To make effective use of the space around a duplicating machine or the like by inserting the top part of an extensile tray between the floor surface of a fixed tray and projected lower rims for making the size of the tray extensible easily in accordance with the change of the size of papers. CONSTITUTION:A fixed tray 2 is fast fixed on a paper supply port or the like of a duplicating machine 1 and others, and on its both side walls 4, plate-shaped projections 5 are provided to face to each other. Meanwhile, an extensile tray 6 with an outer surface to be closely attached to the inner surface of the fixed tray 2 is prepared to be provided with staged gains so that the width of top parts 8 of its side walls 7 may be equalized with the interval between the floor face of the fixed tray 2 and undersides of plate-shaped projections 5 only within a fixed range of the length of the top parts 8. The side wall top parts 8 of the extensile tray 6 are inserted to be extensible between a bottom plate 3 of the fixed tray 2 and the undersides of the plate-shaped projections 5. This construction permits to extend and contract sizes of trays 2 and 6 in accordance with the change of the paper size for making effective use of the space around the machine. |
