Abstract

PURPOSE:To press surely an original with a compact construction and to finish cleanly a copy by such constitution wherein a platen cover having thin walled parts is folded and stored on the outside of the opening/closing region of an automatic feeder while the automatic feeder is in use. CONSTITUTION:Thin walled parts 4a are provided in four places of a platen cover 4 consisting of white rubber, and the one end on the left side thereof is adhered and fixed to the left side of the body 1 of a copying machine. The platen cover is folded and stored on the outside of the opening/closing region of an automatic feeder 3 while the feeder 3 is in use. The feeder 3 is opened upward and the platen cover 4 is extended to cover the original on a platen glass plate 2, then copying is performed to prevent the imprinting of the belt of the automatic feeder 3. The original is thus surely pressed with the compact construction and the copy is cleanly finished.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a copying machine equipped with an automatic document feeder (hereinafter abbreviated as ADF).

Conventional Structure and Problems Conventionally, in copying machines equipped with an ADF, the ADF often uses a large number of belts for conveying documents. When a copying machine equipped with such an ADF is used to copy an original document such as a slip that is smaller than the copy paper, the ADF belt appears in the margin, which is unsightly. When copying thin originals, the belt on the ADF still shows bleed through, which is also unsightly.

The above problem can be solved by placing a white sheet of paper on top of the original in order to make the copy look nice (you have to prepare a white sheet of paper or put it away each time). It was a hassle.

DETAILED DESCRIPTION OF THE INVENTION It is an object of the present invention to provide a copying machine that can solve the above-mentioned problems with a simple structure by improving the platen cover.

Composition of the Invention The present invention has an automatic original loading device that is rotatably opened and closed in a direction that allows it to approach and move away from a platen glass plate for placing documents provided on the upper part of a copying machine main body. In the copying machine, one end of the copying machine main body is fixed outside the opening/closing area of the automatic document feeder, and has at least one bendable thin part, and when the automatic document feeder is used, the copying machine The apparatus is equipped with a platen cover that can be folded and placed or stored outside the opening/closing area of the automatic document feeder on the main body of the machine.

Description of examples Hereinafter, the present invention will be explained based on illustrated embodiments.

1 and 2 show external views of this embodiment, and FIGS. 3 and 4 are front views of the same embodiment.

In those drawings, numeral 1 is the main body of the copying machine, and numeral 2 is a platen glass plate on which a document is placed.

Reference numeral 3 denotes an ADF, which is attached to the copying machine main body 1 so as to be vertically rotatable to open and close in a vertical direction toward and away from the platen glass plate 2. Reference numeral 4 denotes a platen cover, which is sized to sufficiently cover the entire surface of the platen glass plate 2 when extended as shown in FIGS. 2 and 3.

In this embodiment, white rubber is used as the material of the platen cover 4, and thin-walled portions 4a are provided at four locations, and one end portion 4b of the thin-walled portions 4b is fixed to the upper left side of the copying machine body 1 by gluing or otherwise. There is. When using the ADF 3, the platen cover 4 is attached to the chain #i in Fig. 1 so as not to obstruct its opening/closing.
! It can be folded and placed or stored outside the opening/closing area of the ADF shown at 6 (see FIGS. 1 and 4).

In the above configuration, if you want to prevent the ADF belt from appearing in the image while copying (when the original is smaller than copy paper or when the original is thin), open the ADF 3 upward and place the original on the platen. Simply place the original on the glass plate 2, extend the platen cover 4 to cover the original, and then copy. When copying is completed, it is folded again and placed or stored outside the opening/closing area of the ADFa.

It should be noted that if a handle 4C is provided at the tip of the platen cover 4, it will be convenient when extending or folding the platen cover 4.

Effects of the Invention As is clear from the above description, the present invention fixes one end of the platen cover having at least one thin wall portion outside the opening/closing area of the ADF, and when the ADF is used, the platen cover is folded and placed or placed there. By being configured so that it can be stored, the platen cover does not take up space in the normal state (when using the ADF), and does not interfere with the copying machine when a sorter or the like is installed on the main body.

Furthermore, if the platen cover is made of a flexible member such as rubber, no rotational movement is required when using the platen cover, and therefore the platen cover can be easily extended without having to open the ADF upwards all the time. Can be done. Also,
Since the document can be held while sequentially extending the platen cover, the document can be held securely without moving. Further, when attaching the platen cover to the copying machine main body, no large force (moment) is applied to the attaching portion, so the structure of the attaching portion can be simplified, which has many advantages.
