DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG. 8 and 9 are denoted by the same reference numerals, and description thereof is omitted (the same applies hereinafter). 1 is a paper discharge tray. This output tray 1
A first discharge tray 2 in the form of a flat plate disposed on an extended surface of a discharge passage of office equipment, and a second discharge tray 3 slidably held by the first discharge tray 2; Consisting of The first discharge tray 2 is formed of a synthetic resin, and a leg support 7 for slidably holding the leg 4 of the second discharge tray 3 is formed on the lower surface thereof. These leg support portions 7 include a vertical portion 8 along the outside of the leg 4 and a horizontal portion 9 protruding inward from the lower end of the vertical portion 8. In addition, the first paper discharge receiver 2 includes:
The wall surface 1 formed on the lower surface and facing the leg support portion 7
0 and an opening 11 facing the horizontal portion 9 are formed.

In such a configuration, in a state where the paper discharge tray 1 is connected to the paper discharge passage of the office equipment, the second paper discharge tray 3 is pulled out toward the near side with respect to the first paper discharge tray 2. Therefore, the overall length of the paper discharge tray 1 becomes longer. Therefore,
The paper sheet discharged from the paper discharge passage of the office equipment is supported by the first discharge tray 2 and the second discharge tray 3.

In this embodiment, the second paper receiving tray 3 is formed in a U-shape, and the outward spread of the leg 4 is prevented by the vertical portion 8 of the leg supporting portion 7. Since the movement in the direction is prevented by the lower surface of the first sheet discharge receiver 2 and the horizontal portion 9 of the leg support portion 7, if the leg 4 is deformed, the direction of the deformation is limited to the inside. For the same reason, if the leg 4 is displaced when an impact is applied to the second paper receiving tray 3, the direction is limited to the inside. However, even if the leg 4 is deformed inward, the amount of deformation is limited by the wall surface 10, so that the leg 4 can be prevented from falling off from the leg support 7.

In FIG. 1, there is at least an interval of at least about the thickness of the leg 4 between the inner edge of the horizontal portion 9 of the leg support 7 and the wall surface 10. However, the left and right legs 4 are not deformed inward in parallel with each other, and if deformed, they should be bent inward around the corners where both ends of the continuous portion 5 and the legs 4 intersect. That is, the leg 4 is inclined with respect to the horizontal portion 9, and the horizontal portion 9 and the wall surface 10 are arranged so that the end of the leg 4 abuts on the wall surface 10 within a range in which a part of the leg 4 is supported by the horizontal portion 9. Are defined. Therefore, the leg 4 is
It does not fall off between the wall and the wall 10.

In this embodiment, the leg supporting portion 7 is formed by the vertical portion 8 and the horizontal portion 9 that press the outside of the leg 4, but the leg supporting portion is formed by the vertical portion 8 and the horizontal portion 9 that press the inside of the leg 4. 7 is formed, the wall 10 facing the outside of the leg 4
Is formed on the bottom surface of the first paper receiving tray 2 to achieve the same object.

Next, a second embodiment of the present invention will be described with reference to FIGS. 2 is a bottom view of the paper discharge tray 1, FIG. 3A is a longitudinal sectional front view taken along line AA in FIG. 2, and FIG. 3B is a longitudinal sectional front view taken along line BB in FIG. 3 (c) is a vertical sectional front view taken along the line C-C in FIG. 3, and FIG. 4 is a perspective view of a part of the first sheet discharge receiver 1 as viewed from the lower surface side. On both sides of the lower surface of the first paper receiving tray 2,
A pair of guide ribs 12 and 13 for slidably guiding a portion opposite to the continuous portion 5 are formed. Further, a roof portion 14 located on the extension surface of the horizontal portion 9 is formed between the end of the guide rib 13 located inside and the end of the leg support portion 7.

In such a configuration, if the length of the paper sheet is long, the second discharge tray 3 is pulled out in the direction of arrow D in FIG. The second paper receiving tray 3 is pushed in the direction of arrow E. In this case, the rear part of the leg 4 can be guided by the guide ribs 12 and 13. When the rear portion of the leg 4 abuts on the guide rib 13, the inward deformation of the leg 4 can be prevented by the guide rib 13.

Here, when the second paper receiving tray 3 is pulled out in the direction of arrow D corresponding to the longest paper sheet, the stopper 6 bent outward from the rear end of the leg 4 is attached to the leg supporting portion 7. Abuts on the end of the vertical portion 8 of the first paper discharge tray, so that the amount of the second paper discharge tray 3 withdrawn is limited. Is prevented. When the stopper 6 is in contact with the end of the vertical portion 8 of the leg support 7, the rear end of the leg 4 is disengaged from the inner guide rib 13. In this state, as shown by a virtual line F in FIG. Then, the leg 4 is deformed toward the inner wall 10 by the impact,
Even if the rear part of the leg 4 comes off the horizontal part 9 of the leg supporting part 7, the rear part of the leg 4 does not fall below the first sheet discharge receiver 2 because the stopper 6 is supported by the roof part 14.

Next, an embodiment of the present invention will be described with reference to FIG.
A description will be given based on FIG. FIG. 5 is a bottom view of the paper discharge tray 1 and FIG. 6 is a side view of a part thereof. As is apparent from these figures, a plurality of ribs 15 and 16 are formed on both sides of the bottom surface of the first sheet discharge tray 2 along the sliding direction of the leg 4. These ribs 15 and 16 are defined in the shape of a chevron in which the central portion is raised, and the stopper 6 of the leg 4 is provided at the central portion.
Locking portions 17 and 18 which are resiliently locked are formed. The positions of these locking portions 17 and 18 are determined at positions corresponding to the length of the paper sheet.

In such a configuration, when pulling out the second discharge tray 3, for example, when using A4 size paper, the stopper 6 of the leg 4 is locked to the locking portion 17 on the back side. When using B4 size paper, the stopper 6 of the leg 4 is locked to the locking portion 18 on the near side. Thereby, the total length of the paper discharge tray 1 can be determined according to the length of the paper sheet. Since the continuous portion 5 of the second paper receiving tray 3 is also bent upward from the end of the leg 4, the leading edge of the discharged paper sheet can be received and aligned.

Further, one embodiment of the third aspect of the present invention is shown in FIG.
It will be described based on. The present invention is applicable to at least the leg supporting portions 7 of the guide ribs 12 and 13 described with reference to FIGS.
The length of one end on the side is determined to be longer than the length of the leg support 7.

In such a configuration, when a plurality of paper discharge trays 1 are mounted in each of the paper discharge passages of the office equipment 19 and the paper sheets S are discharged to the second or lower paper discharge tray 1, Even if there is a curl curling upward at the rear end of the paper sheet S to be printed, the rear end of the paper sheet S is pushed down by the lower edges of the guide ribs 12 and 13, and the subsequent paper sheet S is guided by the guide ribs. The guides 12 and 13 can guide the front of the leg support 7. That is, the guide ribs 12 and 13 can function as protrusions for preventing the paper sheet S from being caught on the stopper 6 of the leg support 7 or the leg 4.
