Abstract

PURPOSE:To cope with sheets of paper having widths within a defined range by providing a side guide which is provided on a paper feeding cassette and which is moved in accordance with the width of a sheet of paper, a roller guide which is interlocked with said side guide, a roller guide return spring, and a paper feed roller. CONSTITUTION:A paper side guide 2 which is moved in the width direction in accordance with the width of a sheet of paper is provided in a paper feeding cassette 1. A roller guide 4 which slides in the axial direction being interlocked with a paper feed roller 5 is provided on a shaft 4' which is parallel to the shaft 5' of the paper feed roller 5. When the cassette 1 is inserted into a paper feeding port, the guide part 3 of the paper side guide 2 is engaged with the roller guide 4, causing the roller guide 4 and the roller 5 to slide in the (b) direction up to a position corresponding to the width of the sheet of paper. When the cassette 1 is removed, the roller guide 4 aud the roller 5 are returned to their stand-by position due to the energizing force of a spring 7. Thereby, it is possible to cope with sheets of paper having widths within a defined range with one cassette.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a paper feeding power center mechanism for terminal equipment and the like.

[Conventional technology]

Conventionally, in this type of paper feed cassette mechanism, a dedicated paper feed cassette whose paper size is limited by the paper feed cassette is provided with a guide section to move the rollers, or a guide section is provided to move the rollers, or multiple rollers are provided for each paper size. rollers were installed.

[Problem that the invention seeks to solve]

In the conventional paper feed cassette mechanism described above, since it is a dedicated cassette that is limited by the paper size, it has disadvantages such as the inability to use intermediate size paper and the mechanism becoming complicated if multiple rollers are provided. .

[Means for solving problems]

The paper feed cassette mechanism of the present invention includes a paper side guide that can be easily moved according to the paper width on the paper feed cassette, and a roller guide provided on the main body of the paper feed mechanism that moves in conjunction with the paper side guide. It has a return spring that provides tension and a paper feed roller.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the present invention.

A paper guide 2 attached to the paper feed cassette 1 is easily moved on the paper feed cassette 1 according to the content of the paper.

When inserting the paper feed cassette in the direction of arrow a, the paper guide 2
A guide portion 3 is provided that slides along the side wall of the roller guide 4.

With the above mechanism, if the amount of change in the paper is within the range C, when the paper feed cassette 1 is inserted to the specified position, the paper feed roller 5
is set so as to move in the b direction depending on the inside of the paper and always maintain a constant distance from the paper separation claw 6. Next, when the paper feed cassette l is removed, the return spring 7 pushes the roller guide 4 and returns the paper feed roller 5 to the specified standby position.

〔Effect of the invention〕

As explained above, the present invention axially guides the paper side guide on the paper feed cassette and the paper feed roller provided on the paper feed mechanism main body side, which can move in correspondence with the paper. The distance between the paper feed roller and the separation claw that separates the paper according to the width of paper within a certain range is determined by the roller guide and the roller guide that has a return spring that applies tension to the roller guide. It has the effect of automatically keeping it constant.
