Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for performing image processing on sheets, such as a copying machine, in which a required number of sheet cassettes accommodating sheets of different sizes can be added.

[0002]

2. Description of the Related Art Many conventional recording apparatuses, for example, relatively small copying machines, have a plurality of paper cassettes b which can be inserted into a lower portion of a main body a as shown in FIG. Copying is performed on paper c fed from sheet b, and when paper c of a required size is not in sheet feeding cassette b, copying is performed by replacing sheet feeding cassette b prepared separately.

[0003]

However, in the above-described copying machine, since the sheet feeding cassette b protrudes largely to the side of the main body a, a large space is required for installing the main body a. Even if it is reduced in size, the effect of being easily installed in a narrow place is impaired. In addition, since the number of sheet cassettes that can be mounted on the main body a is small, the sheet cassette b must be stored in another place, and there is a problem that a place for storing is required.

On the other hand, the present applicant has filed Japanese Patent Application No. 58-1109.
No. 67 (Japanese Patent Application Laid-Open No. 60-6538) has filed an application for a paper feeding device in which the number of paper feeding cassettes is multi-tiered so that a storage space for the paper feeding cassettes becomes unnecessary. However, in this paper feeder as well, since a part of the paper feed cassette protrudes outside the copying machine main body, the disadvantage that the effect of being easily installed in such a narrow place as described above is impaired is inevitable. The present invention has been made for the purpose of improving the above-mentioned conventional problems.

[0005]

According to a first aspect of the present invention, there is provided a paper feeding cassette including an apparatus main body for recording an image on a sheet and a paper storing section for storing the sheet and provided at a lower stage with respect to the apparatus main body.

A guide for guiding the paper to the apparatus main body so as to be able to supply the paper, and a handle in which a part of an outer wall portion of the paper feed cassette is recessed. The recording device is configured such that the outer wall portion having the recessed portion does not protrude from the outer wall of the device main body.

According to a second aspect of the present invention, there is provided an apparatus body for recording an image on a sheet, a sheet cassette containing the sheet and including a sheet accommodating portion provided at a lower stage with respect to the apparatus body, and the sheet cassette. And a paper supply means for supplying paper, provided below the paper supply cassette, wherein the paper feed cassette is configured to, when viewed from the paper feed cassette, feed the paper fed out by the paper supply means. It is configured to be conveyed to the apparatus main body provided on the side opposite to the supply means, and a guide for guiding the paper supplied from the paper supply means to the apparatus main body is integrally provided. In addition, the recording apparatus is configured such that the paper supply cassette has a handle in which a part of the outer wall is recessed, and the outer wall in which the part is recessed does not protrude from the outer wall of the apparatus main body.

[0007]

According to the present invention, a guide for guiding a sheet to the apparatus main body is provided integrally with a sheet cassette, and a handle having a part of an outer wall portion of the sheet cassette recessed therein is provided. By preventing the recessed outer wall from protruding from the outer wall of the apparatus main body, it is possible to reduce the size of the entire apparatus including the apparatus main body and the sheet feeding cassette.
