Description of the Related Art In a document reading device such as a facsimile or a copying machine, a document table (platen glass) is provided on the upper surface of a main body, and an image sensor provided on the lower surface reads an image of a document placed on the upper surface. In general, an opening / closing cover for pressing a document is arranged above the document table.

Many document reading apparatuses of this type have an opening / closing cover equipped with an automatic document feeding mechanism (ADF) for feeding a document placed on a paper feed tray to a predetermined reading position on a document table. It is convenient to read a plurality of originals collectively, but for a large-sized original that exceeds the reading size, the opening / closing cover is opened and the originals are placed directly on the original table and then read.

[0004]

However, in the conventional document reading apparatus, the operation panel is generally arranged on the front side of the upper surface of the main body and the document table is arranged in the back thereof for the convenience of the operator's operation. However, when the operation panel is arranged on the upper surface of the main body in this way, when a large-sized document is read, the document protruding from the platen is covered on the operation panel, which makes it difficult to operate. In addition, since the document table is far from the operator, it is difficult to position the document on the document table for a large-sized document, and it is difficult to set the document.

The present invention has been devised to solve the above-mentioned problems of the prior art, and its main purpose is to:
An object of the present invention is to provide a document reading device configured to smoothly perform a work when a large-sized document exceeding a reading size is set on a platen and is read.
