Description

[Detailed Description of the Invention] The present invention relates to a document placement device for a copying machine on which documents other than those being copied are placed.

Conventionally, when copying a large number of originals using a copying machine, it is relatively troublesome to handle the originals other than during copying, especially when the originals cannot be placed on the main body of the copying machine. I often copy while placing the original on the front.

When copying with this ashes removed, it is inconvenient to handle the original because it is necessary to remove the original each time the original holding cover is opened.

The present invention has focused on the above-mentioned circumstances, and its purpose is to provide a document support for placing a document with a simple structure, and to allow the document presser cover to slide down when the document presser cover is opened. An object of the present invention is to provide a document placement device for a copying machine that can prevent the above problems and further simplify copying operations.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Reference numeral 1 in FIG. 1 is a main body of a copying machine, and on the top surface of this main body 1 is provided a document mounting table 2 that moves back and forth in the horizontal direction in conjunction with the copying operation of the copying machine.

It moves along the seals 3, 3 of this document placement table 2, and a document holding cover 4 is pivotally attached to one end thereof.

The original holding cover 4 holds down the original 5 to be copied placed on the original placing table 2, and is made of, for example, a rubber sheet.

Further, the original holding cover 4 has one end thereof attached to the original placing table 2.
It is pivotally connected to the hinge 6.6 via a rod-shaped pivot shaft 7.

That is, both ends of the pivot shaft 70 are pivoted to the hinge 6.6,
One end of the document holding cover 4 is fixedly attached to a midway portion of the pivot shaft 7.

Further, a document support 8, which is integrally bent from a rod-like member, is pivotally attached to the pivot shaft 7.

This document support 8 is bent into a coil shape to form pivot parts 9, 9 through which the pivot shaft 7 is inserted, and also serves as a document holding cover.
The receiver on the back side of 49 has a portion 10 and a stopper portion 11 formed therein.

That is, if the document support 8 is rotated and the support part 10 is opened in an outwardly inclined state as shown in FIG.
1 hits a part of the document table 2 to prevent further rotation and maintain it in that state.

Therefore, the document 5 that is not being copied can be placed on the tray 10.

In this case, the document support 8 can be freely rotated independently of the document holding cover 4.

However, a torsion spring or the like may be attached to the pivot portion of the document support 8 to bias it against the back surface of the document holding cover 4.

On the other hand, when the document presser cover 4 is opened, the back surface of the document presser cover 4 comes into contact with the receiver 10 as shown in FIG. 1, thereby preventing the document presser cover 4 from sagging.

Note that the length t of the receiver 10 must be appropriately selected depending on the length of the document 5 to be placed, but generally the longer the better.

However, if the length is too long, a load will be placed on the document table 2, so this point should also be taken into consideration.

Furthermore, if the length t of the receiver section 10 is made extremely short, the document holding cover 4 will become unstable, so it should be avoided.

According to the above configuration, when a large number of originals 5 are to be copied, the receiver of the original document support 8 that holds the originals 5 other than those being copied can be placed on the unit 10. There is no need to remove the document 5 every time the document holding cover 4 is opened (this is convenient).

When the original holding cover 4 is opened, the back side of the original holding cover 4 hits the receiving portion 10, which prevents the original holding cover 4 from sagging, making opening and closing of the original holding cover 4 quick and easy. Since the original holding cover 4 is less bent, the life of the original holding cover 4 can be extended.

Furthermore, since the document support rod is integrally bent and simultaneously pivoted to the pivot shaft of the document holding cover, the document support has a simple structure and is extremely easy to manufacture. be able to.

Although in the above embodiment the document support is made of a rod-like material, the present invention is not limited thereto, and may be made of a thin plate-like material, for example.

As explained above, according to the present invention, it is possible to provide a document support on which a document other than the document being copied is placed with a simple structure, and it is possible to simplify the handling of the document and also to open the document holding cover. This prevents the document holding cover from sagging when the cover is opened and can be opened and closed easily and quickly.

Furthermore, since the document holding cover can be prevented from sagging, no bending action is applied to the document holding cover more than necessary, and its life can be extended.
