Abstract

PURPOSE:To cause scarcely a position shift of an original and to remove simultaneously all the originals when taking them from an original placing table, by superposing as one body an original holding sheet, a positioning frame and a platen cover by a magnet. CONSTITUTION:An original holding sheet 3 consisting of a rectangular and flexible transparent sheet is provided on one side end of an original placing table 2 of a copying machine body 1. Also, an original positioning frame 9 constituted so that an outside frame 4 which can be placed and fixed on this sheet 3, and an inside frame 7 formed by providing a transparent plastic plate 6 marked with an original positioning line 5 on the inside with respect to the outside frame 4 is taken in and out freely by a pull 8 is provided. A platen cover 11 provided with an original holder 10 which has size contained in the original positioning frame concerned 9, has a white lower face and has flexibility is provided so as to be freely openable anc closeable by use of a hinge 12. The sheet 3, the frame 9 and the cover 11 are constituted so as to be magnetizable by use of a magnet 13 at the opposite side of the side where the hinge 12 is provided.

Description

[Detailed description of the invention] The present invention relates to a document positioning device for a copying machine.

When placing a document at a predetermined position on the document table, conventional copying machines handle not only normal-size documents, but also documents of even smaller size, or documents of this small size. This method has the disadvantage that positioning is particularly difficult when reducing/enlarging a document.

The Kokuhatsu 8A was developed to eliminate the drawbacks of the conventional copying machine, and includes a platen cover that covers the dirt on the document table of the copy machine, as well as a document holding sheet and document position 11. It is an object of the present invention to provide a document positioning device for a multi-J1 machine, which can properly position even a very small document of non-standard size in a predetermined position by providing a fixing frame or the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below based on figures showing one embodiment.

FIG. 1 is a partially sectional side view of a document positioning device for a copying machine according to the present invention, and FIG. 2 is a flat view of the document positioning frame.

That is, in the drawings, the unexploded IJJ has a rectangular flexible transparent sheet 3, which is a t/8 paper sheet, on the edge of the copying machine body 1 on the side of the document tray 20. 1iil on the document holding sheet 3! iz, I・
j, ], and an inner frame γ with a document position 11 mark line 5 marked on the inner side of the outer frame 4, and a transparent plastic plate 6 provided with a handle 8. −
C. A platen cover 1 provided with a document positioning frame 9 that can be freely inserted and removed, and a document holder 10 that is large enough to be inserted into the document positioning frame 9 and has a white lower part and is flexible.
1 is provided so that it can be opened and closed freely using a hinge 12, and the document holding sheet 3, document positioning frame 9, and platen cover 11 are attached with a magnet 13 on the side opposite to the side where the hinge 12 is provided. It is constructed so that it can be used for magnetic attachment.

The present invention has the above-described structure, and in order to properly position a very small document of a non-standard size at a predetermined position on the document table 2 of the copying machine main body 1 using the present invention, the following steps are required. Proceed as described in .

That is, first, the original is placed on the original placing table 2 at a position that seems appropriate. Next, place the original holding sheet 3 over the original to prevent it from moving, place the original positioning frame 9 on top of the original holding sheet 3, and insert the plastic plate 6 of the original positioning frame 9 through the sheet. The position of the original is confirmed with the naked eye, and the original is moved along the original positioning line 5 marked on the plastic plate 6 to position it at a predetermined position. When this work is completed, the next step is to use the handle 8 to pull out the plastic plate 6 along with the inner frame I from the outer frame 4, leaving only the original positioning frame 9 and the evening frame 4.
The platen cover 11 is placed over this, and the IQ and fA presser 10 of the platen cover 11 is fitted into the outer frame 4 of the document positioning frame 9 to press the document as a whole.

The above is the document positioning work on the document placement table 2 according to the present invention.

Therefore, the present invention has the original 4f of the copying machine 1, 1 mounting 1) 214 units 2
In order to place the original high on the top of the city 2 ii'i, 7J month high rank 1〆 A, the deciding frame 9 f.

You can set the document at the specified position while visually checking the document positioning line on the Rustic Temporary 6.
The advantage of being able to perfectly position the original is that once the original has been positioned on the original platen 2, the plastic plate 61-1 used for this: Both the inner frame T and the outer frame 4 can be moved by the puller 8. Since it is pulled out, there is no chance that the original positioning line 5 of this glass plate 6 will be copied onto the copy paper during copying, and the 1r'L
When the platen cover 11 is waved over a document that has been fixed, the document is already fixed on the W and document mounting table 2 by the document holding sheet 3, so if the document is moved from its position due to wind pressure, etc. It also has the advantage of not having to say anything.

Further, in the present invention, as described above, the original holding sheet 3, the original positioning frame 9, and the flat cover 11 are connected to the magnet 1.
3, if the configuration is such that these items can be superimposed into a single unit, there will be very little misalignment when these items are superimposed on the original platen 2. It is even more convenient to remove them from the soil because you can do it all at once.
