BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet storage device for stacking and storing sheets discharged from office equipment such as a printer, a copying machine, a facsimile, and an image reading device.

[0002]

2. Description of the Related Art Some office equipment such as a printer, a copying machine, a facsimile, and an image reading apparatus are provided with a drawer-leafable paper storage box or the like for stacking and storing processed paper. An example is shown in FIG. An opening 3 is formed in the outer surface (front surface) 2 of the office equipment main body 1, and a paper storage box 4 having an upper surface opening is inserted into the opening 3 so as to be able to be pulled out. The paper sheet storage box 4 has a paper sheet guide piece 5 bent downward from an upper edge on the back side thereof, an L-shaped protruding piece 6 protruding upward from the vicinity of both sides thereof, and is located on the near side. A handle 7 and guide ribs 8 formed on both side surfaces are formed. The office equipment main body 1 is provided with a guide (not shown) for slidably holding the guide rib 8 and stoppers 9 formed of a cushioning material such as rubber and located on both upper sides of the opening 3. ing.

[0003] Such a paper sheet storage box 4 is usually stored in the back of the opening 3, and the processed paper sheet 10 is guided by the paper sheet guide piece 5 and stacked on the paper sheet storage box 4. When taking out the paper sheet 10 in the paper sheet storage box 4, the user holds the handle 7 and pulls out the paper sheet storage box 4, but the amount of pull-out is limited by the contact between the projection 6 and the stopper 9. The paper storage box 4 does not fall out of the opening 3.

On the other hand, the paper sheets 10 directly stacked on the bottom surface of the paper storage box 4 are connected to the bottom surface of the paper storage box 4 and the lowermost paper sheet 10.
It is extremely difficult to take out the finger A because it is hard to enter between them. For this purpose, cutouts 4a are formed in the bottom and side surfaces of the paper storage box 4, and the fingers A are inserted into the cutouts 4a to stack the paper sheets 10 stacked.
A method of gripping one side has been considered.

[0005]

[Problem to be solved by the invention] Notch 4
The method of taking out the paper sheet 10 by forming a is improved in taking out the paper sheet 10 compared to the case where the paper sheet 10 is simply stacked on the bottom surface of the paper sheet storage box 4. Since the length and the position are restricted, it is hard to say that this is the best method, and the finger A may be cut at the edge of the notch 4a. In order to prevent the injury of the finger A, it is conceivable to cover the edge of the notch 4a with a protective member. In this case, the paper discharged because the protective member protrudes from the inner surface of the paper sheet storage box 4 is considered. It interferes with the leaves 10, thereby easily causing a jam. The method of covering not only the edge of the notch 4a but also the entire surface of the paper sheet storage box 4 with the protective member can prevent the occurrence of a jam, but is unsatisfactory as the improvement of the take-out property of the paper sheet 10. .

SUMMARY OF THE INVENTION The present invention is directed to a paper storage box having an upper surface opening which is removably inserted into an opening formed on an outer surface of an office equipment main body, and a paper storage box at the back of the paper storage box. A paper sheet mounting plate is provided at the fulcrum portion so as to be raised and lowered and is extended toward the front side, and the paper sheet mounting plate is lowered inside the office equipment body in the process of pulling out the paper sheet storage box. A support portion is provided, and an inclined surface is formed on one of the sheet mounting plate and the support portion that abuts on each other, and is gradually inclined upward in the drawing direction of the sheet storage box.

[0007]

According to the present invention, while the paper sheet storage box is being pulled out, the paper sheet mounting plate is supported by the support portion provided on the office equipment, but is formed on one of the paper sheet mounting plate and the support portion. The sheet placement plate receives pressure from below and rotates upward around the fulcrum portion by the inclined surface, so that the sheet can be lifted upward from the bottom surface of the sheet storage box. It is easy to take out the paper leaf by holding an arbitrary position of the leaf.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. The same parts as those in the conventional example described above are denoted by the same reference numerals, and description thereof is omitted. A fulcrum shaft 11 is provided on the back side of the paper sheet storage box 4 as a fulcrum that is orthogonal to the discharge direction of the paper sheet 10, and the fulcrum shaft 11 has a paper sheet mounting plate 1 that supports the paper sheet 10.
The back side of 2 is held up and down freely. On both sides of the sheet placement plate 12, a front side (sheet ejection direction side)
A rib 14 having an inclined surface 13 which is gradually inclined upward toward the center is integrally formed, and a long hole 15 for releasing the rib 14 is formed on the bottom surface of the paper sheet storage box 4. In the vicinity of the lower edge of the opening 3 of the office equipment main body 1, a guide roller 16 as a support for supporting the rib 14 is provided.
Are provided rotatably.

In such a configuration, usually, FIG.
As shown in FIG. 1A, the paper sheet storage box 4 is inserted into the back of the opening 3, and its front surface does not protrude from the front surface 2 of the office equipment main body 1. In this state, the front side of the sheet placement plate 12 is supported by the bottom surface of the sheet storage box 4, and the rib 14 is
Protruding from. In this state, the paper sheet 10 processed inside the office equipment main body 1 is stacked on the paper sheet mounting plate 12.

In the initial process of pulling out the paper box 4,
As shown in FIG. 2B, the rib 14 approaches the guide roller 16, and as shown in FIG.
When the sheet storage box 4 is pulled out until it comes into contact with the sheet, the inclined surface 13 of the rib 14 rides on the guide roller 16 in this process, so that the sheet placement plate 12 rotates upward about the fulcrum shaft 11. Then, the paper leaf 10 is lifted above the paper leaf storage box 4.
Thus, an arbitrary position from both sides (right side) of the central portion of the paper sheet 10 to the front edge can be easily taken out with one hand or both hands, as in the conventional example shown in FIG. In addition, there is no risk of injury due to the notch 4a.

A guide roller 16 for supporting the rib 14
Is rotated, the pull-out operation and the storing operation of the paper sheet storage box 4 are smoothly performed. However, a support portion as a fixed object may be provided in the vicinity of the opening 3 instead of the guide roller 16.
Further, by arbitrarily determining the position and the inclination angle of the inclined surface 13 of the rib 14, the sheet placement plate 12 is raised at an arbitrary speed and at an arbitrary angle at an arbitrary time during the process of pulling out the sheet storage box 4. be able to.

Although not shown, a protrusion or a roller projecting below the sheet storage box 4 is provided on the lower surface of the sheet mounting plate 12 at a predetermined distance from the fulcrum shaft 11, and the protrusion is provided. Alternatively, the same object can be achieved by providing a support portion for supporting the roller from below inside the office equipment main body 1 and forming an inclined surface on the upper surface of the support portion, which is inclined upward in the drawing direction of the paper sheet storage box. can do.
