Abstract

PURPOSE:To enable numbers of chassis in a same form to be piled up and down one another stably without any position gap by forming a receiving and positioning sections on the upper side of the chassis. CONSTITUTION:A chassis receiving section 2 is formed on the both sides of a chassis 1 which has a space to receive sheets of copying paper, so as to allow another upper chassis 1 to be accepted. The chassis receiving section 2 is partially cut out as a positioning notch 3. And an auxiliary position projection 4 is located at the lower side of a chassis which is to be piled on the above said chassis. Now the positioning notch 3 is engaged with the auxiliary positioning projection allowing numbers of chassis 1 to be piled up and down stably without any position gap.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a paper feed cassette used in a copying machine.

Conventional configuration and problems Copying machines such as electrophotographic copying machines have two or more types of paper feed cassettes for each size of paper to be stored, such as A4 size. The method of use is to keep one for paper size and one for B4 size, and then insert and remove paper feed capacity cents of the required size from the paper feed slot of the main body of the copying machine. Tabletop copying machines are often placed on a special table called a dedicated stand, so a temporary storage shelf for the paper feed cassette was formed on the dedicated stand in advance and removed from the main body of the copying machine. The paper will be temporarily stored in the paper feed cassette 1.

However, if the copying machine is installed on a table such as an office desk instead of a dedicated stand, there is no temporary shelf for the paper cassette that was on the dedicated stand, and the paper cassette is placed on a nearby office desk. They will be placed on top of each other. Conventional paper feed cassettes have a housing with an opening at the top, and some have lids attached to the opening that can be opened and closed, but when placed on top of each other, The paper cassette would shift due to some kind of lifting motion, and the paper feed cassette that was stacked on top would fall off, and when conditions were bad, it would almost fall under the Shinmu desk, so I had to put it away. This has the drawback of not only scattering paper but also frequently causing accidents in which the paper feed center itself is damaged.

OBJECT OF THE INVENTION The present invention aims to eliminate the drawbacks of the above-mentioned conventional examples and to provide a paper feed cassette that does not shift its position even when stacked one on top of the other. A paper cassette is constructed by forming a housing holder and a positioning part on the upper surface of a housing that has a space for storing copy paper, so that the same housing can be positioned and loaded.

Description of examples Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a paper feed cassette according to an embodiment of the present invention. 1 is a housing having a space for storing copy paper, and 2 is a housing holder with both sides of the housing 1 projecting out. Parts 3 and 3 are positioning parts formed by cutting out a part of part 2, and 4 is a positioning auxiliary part protruding from the bottom of the case 1. . Figure 2 shows a cross-sectional view of the two paper feed cassettes shown in Figure 1 placed one on top of the other, and each part is numbered the same as in Figure 1.
There is a suffix F on one side to distinguish between the paper feed cassettes.
a and a suffix b are attached to the numbers.In addition, in the embodiment, an example in which the positioning auxiliary part 4 is provided protruding below the paper feed cassette is shown, but the housing holder is not a part. The positioning portion and the positioning portion are not limited to the present example, and the housing support portion and the positioning portion may be formed so as to surround the lower part of the paper feed cassette from three or four directions without protruding the positioning auxiliary portion. good.

Effects of the Invention As detailed above, the paper feed cassettes according to the present invention can be stacked stably on top of each other as if they were stacked on top of each other, so they can be stacked neatly on a desk without a dedicated stand, and can be stacked neatly on a desk instead of being cluttered like in the past. This has the advantage that the paper feed cans that should have been placed in a stack will not accidentally slip down and scatter the stored paper, or damage the paper feed can itself. .
