Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a paper feed cassette that is housed in a paper feed section of a copying machine and used to supply paper, and is particularly applicable to operations such as taking out paper. The present invention relates to a paper feed cassette that is configured to easily perform the following operations.

(Prior Art) In conventional paper feed cassettes, the size of the paper storage section of the paper feed cassette is often determined according to the size of the paper, and the side walls of the cassette and the paper are , are normally held in a nearly intimate state.

When inserting paper into the storage section of this paper cassette, you can easily set it by simply opening the cover of the paper cassette and inserting it from above. When taking out the paper, there is a tight space between the wall member that defines the storage area and the area around the paper, so it is impossible to insert your finger and take out the paper. , it is necessary to use a method such as turning the paper cassette upside down and letting the paper fall.
Such handling may cause inconveniences such as damage to the paper.
This also causes paper to be wasted.

Furthermore, conventional paper feed cassettes often have a flat top plate and bottom plate. Furthermore, since the peripheral wall is not particularly provided with a convex part, there is no part to put your fingers on when handling it.
When removing the paper feed cassette from a copying machine, it is necessary to pull it out with relatively strong force, but since there is no catch, it is often necessary to handle it inconveniently, such as holding it with both hands and pulling it out. be.

(Problems to be solved by the invention) The present invention solves the above-mentioned drawbacks of the conventionally used paper cassette.It improves the handling of the paper cassette and makes it easier to take out paper. It is an object of the present invention to provide a paper feed cassette that can be easily loaded.

(Means and effects for solving the problems) The paper feed cassette of the present invention has a plurality of rear ribs protruding from the rear end wall of the paper feed cassette toward the paper storage section. Therefore, a space is formed between the paper and the rear part of the paper, and the rear side of the bottom plate of the paper feed cassette is made to protrude downward to form a convex part. There is a space in communication with which you can insert your finger.

Therefore, when taking out paper from the paper feed cassette of the present invention, it is possible to insert a finger into the space and lift the rear end of the paper to easily take out the paper. When taking out the paper feed cassette from the paper feed cassette, it is possible to easily pull it out by placing your hand on the protrusion.

(Embodiment) The structure of the paper feed cassette of the present invention will be explained according to the illustrated embodiment. As shown in FIG. Side ribs 3 are formed that project toward the inside, and the rear end wall 6 is provided with a plurality of rear ribs 7 that project inward. Then, the rear end of the paper 10 and the rear end wall 6 of the paper feed cassette.
A space 9 is formed between them.

Further, the rear part of the bottom plate 4 of the paper feed cassette 1 of the present invention is provided with a convex portion 5 that projects downward, and a concave portion 9a is formed inside the convex portion 5 following the space 9. A plurality of lower ribs 8, 8 are provided in parallel to partition the space, and the upper surface of the rib 8 is formed to match the upper surface of the bottom plate 4.

Further, the lower rib 8 is formed as a member that prevents the paper from absorbing moisture and sagging when the paper is left stored for a long period of time, and also serves to reinforce the convex portion 5. Ori,
As will be described later, even if the convex part 5 is held when the paper feed cassette 1 is pulled out from the copying machine, its strength can be sufficiently exhibited.

The paper storage section of the paper feed cassette 1 is located in the rib 3 of the side wall.
The paper 10 is positioned within the range regulated by the rear rib 7 and the rear rib 7, and the paper 10 is housed in a positioned state, with the rear end resting on the lower rib 8.

As shown in FIG. 2, when taking out the paper 10 from the paper feed cassette 1 of the present invention, insert your finger from the space 9 toward the recess 9a and pull up the rear end of the paper 10. , the space 9 and the recess 9a are set to be wide enough to insert a finger, but the distance between the ribs provided in the recess 9a is such that each finger can be inserted. It should be large enough to accommodate each person. Furthermore, if the paper is left in the paper feed cassette for a long period of time and the paper absorbs moisture and its stiffness decreases, there is a way to prevent the paper from hanging between the lower ribs. , it is also better not to make the interval between the lower ribs too wide.

Also, not only when storing new paper 10, but also when adding paper, take out the previously stored paper, put another paper underneath, and store the paper with the edges aligned. There is enough space at the rear of the paper feed cassette when inserting the paper into the paper feed cassette.

When removing paper cassette 1 from the copying machine,
In the state shown in FIG. 3, place your finger under the protrusion 5, press the cover 11 from above and below, and pull out the paper feed cassette 1. In this case, a relatively large force will be applied to the convex portion 5, but since the convex portion 5 of the paper feed cassette of the present invention is reinforced from inside, it can sufficiently resist that pressure. It's becoming like that.

In a normal paper feed cassette, the front and rear, left and right side walls and bottom plate are integrally formed by plastic injection molding, etc., but each member of the paper feed cassette 1 of the present invention is of course integrally formed. It can be molded, and the cover can be manufactured and attached separately.

Furthermore, the structure of the paper feed cassette of the present invention can exhibit good effects when applied to a normal paper feed cassette in which a paper support plate is swingably provided on the bottom plate. It can be applied to all types of paper feed cassettes.

Further, in the embodiment of the present invention described above, the rear rib 7 and the lower rib 8 are provided separately, and the convex portion 5 is also formed as a relatively small piece in the center of the paper feed cassette. However, in the paper feed cassette of the present invention, the shapes of these members are not limited to the above-mentioned embodiments. Of course, changes are possible.

(Effects of the invention) Since the paper feed cassette of the present invention has the above-described configuration, it is possible to easily take out paper from the paper feed cassette and pull out the paper feed cassette from the copying machine. It makes it possible. Since the paper feed cassette can be handled more easily, the operator's labor can be reduced.

In addition, the paper feed cassette of the present invention can be manufactured in exactly the same manner as the conventionally used manufacturing method, and there is no major change in the manufacturing cost. It can be easily attached to a copying machine, thereby reducing the burden on the operator.
