Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a copying machine, a facsimile,
The present invention relates to improvement of a paper feed tray or a paper discharge tray on which paper is placed, which is used in an image forming apparatus such as a printer.

[0002]

2. Description of the Related Art When a large-sized sheet is used in a conventional image forming apparatus, for example, as a paper tray used in a copying machine or a facsimile machine which uses the large-sized sheet,
It is known that a fan-shaped first paper tray and a second paper tray, which are axially supported at a predetermined position, are provided with a link mechanism that keeps them facing each other in cooperation with each other to hold a sheet for an arbitrary document width. (JP-A-2-231)
22). However, when opening in a fan shape, not only a large space is needed at the bottom of the main tray in order to secure the strength of the paper tray fulcrum of the auxiliary tray, but the length of the auxiliary tray is not more than the width of the main tray as much as possible. There was a problem that it was limited to.

In addition, in the document feeder, for example, when a large-sized document is placed on the document tray, the auxiliary tray that is folded in a single stage with respect to the document tray (tray body) is rotated. There is also known a technique in which a document is placed from the document tray to the auxiliary tray by pulling it out (see JP-A-2-89748). However, in the method of rotating and pulling out the auxiliary tray that has been folded in one stage in this manner, the original area occupied by the original tray must be half or more of the maximum original size, and the original tray occupies too large area. There was a problem.

[0004]

The above-mentioned conventional image forming apparatus has a limit in reducing the length of the auxiliary tray.
There is a problem that not only a large space is required, but also the structure of the tray is complicated and there is a risk that the sheets placed on the tray may fall.
