Abstract

PURPOSE:To copy an original without the trace of a belt and to open and close easily an original retaining sheet by providing the original retaining sheet, to which an attracting means is stuck, and a means to be attracted which the attracting means can attract to and separate from the copying machine side and attaching and detaching freely the original retaining sheet to and from the copying machine body by the attracting means and the means to be attracted. CONSTITUTION:A magnet 10 is stuck as the attracting means to one end on the lower face of an original retaining sheet 9, and an iron plate 12 is stuck as the means to be attracted in the deep side on an upper face 1a of the copying machine body. The original retaining sheet 9 is placed on the upper face 1a as one body together with the magnet 10 as shown by an arrow B, and the magnet 10 and the iron plate 12 are attracted to each other to stick the original retaining sheet 9 to the copying machine body 1. A handle part 9a of the original sheet 9 as shown by arrows D and D'. At this time, the magnet 10 and the iron plate 12 are attracted to each other as they are, and the original retaining sheet 9 is opened and closed by bending of the original retaining sheet 9 itself. The original retaining sheet 9 consists of a resin; and when it is closed, it is brought closely into contact with an original platen glass 8 to bring closely an original 5 into contact with the original platen glass 8 completely.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a copying machine with a document holding device.

Conventional Structures and Their Problems In recent years, copying machines that have high copy speeds and are capable of making a large number of copies in a short period of time have become popular. Such high-speed copying machines are often used with an automatic document feeder installed as an option.

A conventional copying machine will be described below with reference to the drawings. FIG. 1 is a perspective view of the automatic document feeder in a mounted state. In the figure, 1 is the main body of the copying machine, and when a document 6 is set in the document setting section 2 of the automatic document feeder, the document 5
The document is transported to a predetermined position by the document transport section 3, and after being copied there, the document is discharged to the tray 4. The document transport section 3 of the automatic document feeder has a belt 6 for feeding the document, as shown in FIG. When copying a document by automatic feeding by taking advantage of the function as an automatic document feeder, the document conveying section 3 is used with it closed. This part also serves as the platen cover of the copying machine, and can be opened and closed by holding the handle 7, allowing you to directly place the original onto the platen glass 8.
It is also possible to copy it on top of the .

However, when copying is performed using the method described above, the marks of the belt 6 will be visible when the original is copied using thin originals such as tracing paper. Further, since the document transport section 3 has a built-in document feeder, it is heavy and has the disadvantage that it cannot be opened and closed easily unlike a normal platen cover of a copying machine. ? ,
.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention has been made to provide a method for copying without leaving any traces of the automatic document feeder's belt, which can be opened and closed easily, and which can also be used for the original purpose of the automatic document feeder.
It is an object of the present invention to provide a copying machine with a document checking device that can prevent its functions from being hindered.

Structure of the Invention In order to achieve the above-mentioned object, the present invention fixes a suction means to a document flap sheet that performs the same function as a platen cover of a copying machine, and fixes it and a removable suction means to the main body of the copying machine. By attracting and separating the suction means and the suction target means, it is possible to configure the original document holding sheet to be detachable from the main body of the copying machine.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 is a perspective view of the copying machine in which the document checker sheet 9 and the automatic document feeder according to the present invention are installed. Also, the same reference numerals are given to the same components as in the conventional example.

The manuscript holding sheet 9 has a magnet 1 on the bottom surface of one end as an adsorption means.
o, and an iron plate 12 is fixed to the rear side of the upper surface 1a of the main body of the copying machine as means to be attracted. By placing the original tag sheet 9 together with the magnet 1o on the upper surface 1a of the copying machine main body 1 as shown by arrow B, the magnet 1o and the iron plate 12 are attracted to each other and the original tag sheet 9 is fixed to the copying machine main body 1. let

FIG. 4 is a side view of FIG. 3 as viewed from the direction of arrow C, and the document holding sheet 9 is opened and closed as shown by arrows D' by holding a handle portion 9a. At this time, the magnet 10, the iron, and the plate 12 remain attracted to each other, and the document flap sheet 9 itself bends to open and close. The manuscript cover sheet 9 is a resin sheet, has low rigidity, can be easily bent, and when closed, comes into close contact with the manuscript table glass 8, so that the manuscript table 6 is completely brought into close contact with the manuscript table glass 8. It is possible. If you want to remove the original valve sheet 9, pull the original valve sheet 9 toward you or upwards from the copying machine main body 1, and the stone 10 and iron plate 12 will be separated, so that the original valve can be removed. E sheet 9
can be easily removed.

Effects of the Invention As described above, according to the present invention, even in a copying machine equipped with an automatic document feeder, when copying a thin document, by installing a document support sheet, the automatic document feeder can be moved from the platen. There is no need to open and close it as a cover.

Particularly, since this document check sheet is removable, it can be easily removed when operating the copying machine by utilizing the original functions of the automatic document feeder. Therefore, a copying machine equipped with an automatic document feeder can be used more conveniently.
