Abstract

PURPOSE:To enable the feed of paper in two perpendicular directions, by opening holes in two mutually perpendicular sides of the bottom of a paper feed cassette and providing a bottom plate which is located on the bottom of the cassette and has a fulcrum near at least one of the other sides of the bottom. CONSTITUTION:A cassette case 5 is made square, preferably. Two holes 6a, 6b are opened in two mutually perpendicular sides of the bottom of the case 5 so that the holes extend in the bottom and side walls of the case. Small holes 7a, 7b, 8a, 8b are opened in the bottom of the case 5 near the other two mutually perpendicular sides in which the holes 6a, 6b are not located. A bottom plate 9, which is put in the case 5, is provided with legs 10a, 10b, 11a, 11b on two mutually perpendicular sides so that the legs can be loosely fitted in the small holes 7a, 7b, 8a, 8b. When the case 5 is set in a changed direction of fitting in a copying machine, the plate 9 is inclined in one of two perpendicular directions, with the legs 10a, 10b or 11a, 11b as fulcra.

Description

[Detailed description of the invention] (Application field) The present invention relates to a paper feed cassette installed in a copying machine.

(Prior Art) A conventional device of this type will be explained with reference to FIGS. 1(a), (bl) and FIG. 2. FIG. Figure 1 is shown. In the figure, 1
is a cassette case, and a hole 2 is bored in the bottom surface of the case. Further, as is clear from FIG. 1(b), two small holes 3a and 3b' are bored near the side of the bottom surface.

FIG. 2 shows the bottom plate 4 housed in the cassette case 1. As shown in FIG. Bottom plate 4 has legs 4a and 4.
b are provided, and when the anti-bottom plate 4 is inserted into the cassette case 1, these legs 4a and 4b
are loosely fitted into the small holes 3a and 3b on the bottom of the cassette case, respectively.

Copy paper is placed on a bottom plate 4 housed in a cassette case 1. When the cassette case 1 with copy paper set therein is mounted on a copying machine, the cassette case 1 receives a vertical upward force from the copying machine through the hole 2. Therefore, the bottom grade 4 is small hole 3 a + 3
It rotates using the legs 4a and 4b loosely fitted in the bottom plate as fulcrums, and lifts up the copy paper on all four sides of the bottom plate diagonally. Therefore, the copy paper is sent out in the two directions Cζ of the arrow shown in FIG. 1 (al) and becomes cheaper.

Since the conventional paper feed cassette had the above configuration,
There was a drawback that paper could only be fed from one direction with one paper feeding cassette. Additionally, if you try to change the feeding direction of the copy paper, you will need another paper cassette, and in the end, you will need two cassettes, one for vertical feeding and one for horizontal feeding, which is wasteful. It had the disadvantage of being economical.

(Objective) The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to
To provide a paper feed cassette capable of feeding paper in the horizontal and vertical directions with one cassette.

(Overview) The present invention is characterized in that, in a paper feed cassette for a copying machine having a rectangular bottom, a hole is formed approximately in the center of each of two mutually orthogonal sides of the bottom; A bottom plate having a branch on at least one transparent side of the two sides on which the hole is not drilled is disposed on the bottom surface lζ.

(Example) The present invention will be explained below using examples. FIG. 3 is a perspective view of one embodiment of the present invention, and FIG. 4 is a perspective view of a bottom plate used in this embodiment.

In FIG. 3, the cassette case 5 preferably has a square shape, and two holes 6& and 6b are bored from the side to the bottom. These holes are formed so as to span each of the two mutually orthogonal sides of the bottom surface.

Further, the holes 6a and 6b are provided on the bottom of the cassette case 5.
A small hole 71 is placed near the other two orthogonal sides that are not covered.
7b, 8a and 8b are provided.

On the other hand, as shown in FIG. 4, the bottom plate 9 has legs 10a, 10b+] and llb on two mutually orthogonal sides. When this bottom plate 9 is inserted into the cassette case 5, the legs 10a and 1
0b loosely fit into the small holes 7a and 7b, -force, foot 1
1a and llb fit loosely into the small holes 8IL and 8b, respectively.

Fig. f45 and Fig. 6 show how copy paper is loaded into the paper feed cassette having such a structure and set in a copying machine. In FIG. 5C'i, when the copy paper 12 is fed in the direction of the arrow X, that is, when it is fed horizontally, the paper feed cassette 5 is advanced in the direction of the arrow X and the copying machine IC is installed. Then, the parts 7 provided in the copying machine apply an upward force to the bottom plate 9 through the hole 6a formed in the bottom of the cassette case. Therefore, the bottom plate 9 rotates using the foot 11 a p 1 l b as a fulcrum. Therefore, the copy paper 12 on the bottom plate 9 is tilted as shown in FIG.
Drizzle appears in the direction of arrow X.

FIG. 6 shows the case where copy paper 12 is fed in the direction of arrow Y.
In other words, this shows the case of vertical feeding. In this case, the cassette case 5 is advanced in the direction of the arrow and set in the copying machine.

Then, as in the case of lateral feeding, a force acts upward through the hole 6b, and the bottom plate 9 moves the legs 10a, 10
b) It can be lifted up using nine fulcrums. Therefore, the copy paper 12 on top of this is lifted. Therefore, the copy paper 12 can easily come out in the direction of the arrow Y.

(Effects) As described above, according to the present invention, simply by setting the cassette case in the copying machine by changing the direction of the mounting force,
Copy paper can be fed vertically and horizontally. Therefore, it is possible to feed paper both in the horizontal and horizontal directions with one paper feed cassette, which is economical and easy to operate.
