Abstract

PURPOSE:To make it possible to easily set the position of a partition plate in accordance with the size of stored papers, by arranging the partition plate in such a way that the latter may be rotated from a position perpendicular to the bottom plate of a cassette body to the bottom plate side, and as well be held in the perpendicular position. CONSTITUTION:A partition plate 6 is arranged in a cassette body 1 in the position corresponding to the trailing end of half-size papers stored in the cassette body 1 so that the partition plate may be rotated from a position perpendicular to the bottom plate 1a of the cassette body 1 to the bottom plate 1a side and be held in the perpendicular position. That is, when the size of papers to be stored in the cassette body 1 is changed from the full size to the half-size, the papers may be stored in the cassette body 1 by rotating the partition plate 6 and extending the same along the bottom plate 1a of the cassette body 1, and further, when the size of papers are changed from the half-size to the full size, it may be sufficient by simply rotating the pratition plate 6 without removing from the cassette body 1. Accordingly, the setting of the partition plate 6 upon changing paper sizes is satisfactorily made, and as well the partition plate 6 which is unnecessary upon storing of the full size papers, may be prevented from being lost.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper feeding cassette that stores sheets of paper to be sequentially fed to a machine or the like and can be used for a plurality of types of paper of different sizes.

A conventional paper feed cassette like the one above, which has a C-shaped cassette that allows you to set two or more types of paper,
The paper size dividers installed inside the cassettes were all removable, which made them difficult to operate, and when using the maximum size of paper in the cassette, the dividers had to be removed from the cassette, which was troublesome. There are drawbacks such as there is no storage space for the removed partition plates, and the partition plates and their mounting screws can be lost.

The present invention has been made to eliminate and improve the above-mentioned drawbacks of the prior art, and allows the partition plates to be manipulated into containers according to the size of the paper to be stored, and to prevent the partition plates from being lost when not in use. The present invention is intended to provide a paper feed cassette that has the following features.

Embodiments of the present invention will be described below based on the drawings.

This embodiment is for a paper feeding cassette used in a copying machine, and 8 in the figure is a cassette main body, and a swinging bottom 2 is provided at the leading end in the paper feeding direction with a spring biased upward. A snapper 3 for handling paper is provided. Figure 1 shows the state in which full-size paper 4 is stored in the cassette main body #, and Figure 2 shows the state in which half-size paper 5 is stored. A partition plate 6 is attached to the portion to support the end of the paper 5 of this barf suspension.

The partition plate 6 has shaft portions 6α protruding from the lower portions of both ends, which are fitted into holes provided in both side walls of the cassette body 1 so as to be freely rotatable in the paper feeding direction. The partition plate 6 is configured to rotate in a range from perpendicular to parallel to the bottom plate 1a of the cassette body 1.

That is, both ends of the partition plate 6 are located in the recesses 7 on both side walls of the cassette body 1, and the walls of the recesses 7 and the projection ε separate the partition plate 6.
The projections 6b are held together in a vertical state, and are rotated past the projections 8 by elastic deformation to a parallel state. A recess 9 is provided in the bottom plate 1α of the cassette body 1, and the parallel partition plate 6 is housed in the four parts 9. The partition plate 6 is made of a material with some degree of elasticity, such as synthetic resin, and is connected to the cassette body 1.
When assembling it into a machine, it is assembled with a slight bend as shown in FIG.

In the above configuration, when storing full-size sheets 4 in the cassette main body 1, the partition plate 6 is rotated beyond the protrusion 8 and is stored in the recess 9 of the bottom plate ja of the cassette main body 1.

On the other hand, when storing half-sized sheets 5 in the cassette main body 1, the partition plate 6 is erected and supported by the projections 8.

FIG. 7 shows another embodiment of the present invention, in which a recess 7 of the cassette body 1 and a partition are provided in place of the projection '8 shown in FIG. 3 as a mechanism for holding the partition plate 6 in a vertical state. A magic tape (trade name) 10 may be interposed between the partition plate 6 and the partition plate 6 to hold the partition plate 6 in a vertical state. Although not shown in the drawings, instead of the Velcro IO, a rubber magnet with double-sided adhesive tape and a metal suction plate may be attached to the partition plate 6 or the cassette body 1 side.

In each of the above embodiments, one partition plate 6 is provided, but two or more partition plates 6 may be provided. For example, if the full size is M3, B4°A4. B5... can be provided with a partition plate.

Since the paper feed cassette according to the present invention is as detailed above, when changing the size of paper stored in the cassette body 1 from full size to half size, the partition plate 6 can be rotated without being removed from the cassette body 1. The cassette can be moved and stored along the bottom plate 1a of the cassette body 1, and vice versa, the partition and cutting plate 6 can be simply rotated. Even when the full-size partition is stored, the unused partition plate 6 will not be lost.
