Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary device for copying improper printed matter of paper quality using an office copying machine.

[0002]

2. Description of the Related Art Conventionally, in printed matter of inappropriate paper quality (magazines, books, etc.), the printed surface of the next piece of paper is seen through the printed piece of paper, or the printed surface on the back side is reflected between the lines of the copied paper piece. Then, there is a problem in that the copy will be stained if copied as it is.

[0003]

SUMMARY OF THE INVENTION In order to solve the problems described in the prior art, an attempt is made to prevent stains on the finished product by using a simple tool.

[0004]

In order to achieve the above object, an opaque thin plate is inserted between a sheet to be copied and the next sheet to block harmful transmitted light between the sheets.

If the words on the back side of the paper sheet to be copied are reflected between the lines on the front side of the paper sheet, the opaque thin plate is made to have the same color tone as the ink printed on the back side of the paper sheet, and is applied to the back side of the paper sheet. This reduces the effect on the surface of the piece of paper.

In order to match the color tone of such an opaque thin plate, an appropriate 1-2 sheet is selected from a plurality of colored transparent thin plates each having a unique color tone, and is selected as the opaque thin plate. Perform on a white surface.

In order to easily and surely hold the colored transparent sheet, a transparent film is attached to the opaque sheet, and it is folded on the white surface of the opaque sheet, and the colored transparent sheet is put in it and used. . The same effect can be obtained even when the independent transparent film is folded and used.

[0008]

When printed on a highly transparent paper sheet or an extremely thin paper sheet, the words printed on the second sheet can be seen clearly. This is because the light input from the first surface passes through the sheet and is reflected from the second surface, which is visible from the first surface. By inserting an opaque sheet in between, harmful transmitted light rays are blocked, and the second lexical word becomes invisible.

[0009] If what is printed on the back side of the piece of paper to be copied appears on the front side, an opaque thin plate of the same color as the printing ink on the back side is applied to the back side so that ink adheres from the front side. This makes it difficult to distinguish between a portion that is present and a portion that is not attached, and dirt reflected on the surface is reduced.

[0010] From a plurality of colored transparent thin plates having different shades, an appropriate 1-2 sheets are selected and overlaid on the white surface of the opaque thin plate, whereby an opaque thin plate having the same color as the printing ink is obtained. it can. Therefore, the above-described treatment can be performed by applying it to the back surface of the paper sheet to be copied.

[0011]

Embodiments will be described with reference to the drawings.
As shown in FIG. 1, a piece of paper 1 to be copied and a next piece of paper 2
By inserting an opaque thin plate 3 made of something like a plastic thin plate or aluminum foil (foil),
Blocks harmful transmitted light between the two pieces of paper and removes smudges on the side to be copied.

In FIG. 2, the back surface 9 of the paper sheet 1 to be copied
Is printed on the surface 8 to be copied, the opaque thin plate whose tone is appropriately adjusted is applied to the back surface 9 of the surface to be copied, thereby making the surface of the surface to be copied less noticeable. .

The opaque thin plate 3 is formed by laminating two plastic thin plates of white and black, and printing on one substrate 6 such as aluminum foil (foil). Leave the other side black on white, and usually the black side 4
Use Further, the colored transparent thin plate 7 is made of a cellophane paper or a vinyl film, and 1-2 sheets are selected from a plurality of sheets having different shades, and are stacked on the white surface 5 of the opaque thin plate. use. Adjustment of the color tone of the opaque sheet in each case is carried out by selecting an appropriate one from the above.

The black surface of the opaque thin plate is applied to the back surface 9 of a printed material using dark black ink to remove stains reflected on the surface (front surface) to be copied.

However, since the density of the black ink to be printed may be different in some cases, a plurality of colored transparent thin plates 7 are mixed with a gray colored transparent thin plate having a different density. .

If there is no printing on the back surface 9 of the printed piece of paper and it is left blank, the white surface of the opaque thin plate is applied to the back surface 9 for use.

As shown in FIG. 3, a transparent film 10 is attached to an opaque thin plate, which is folded on a white surface 5 and a colored transparent thin plate 7 is put in the transparent film 10 to easily and surely hold the colored transparent thin plate. To

Instead of attaching a transparent film to an opaque thin plate,
The same effect can be obtained even if the independent transparent film is folded in two and the opaque thin plate and the colored transparent thin plate are put therein.

In the case of precisely copying a crowded special printed surface, it is necessary to select one of a plurality of colored transparent thin plates having various colors corresponding to the partial colors of those printed on the back surface 9. An optimal colored transparent sheet can be made by selecting a suitable transparent sheet and cutting it on the underlying colored transparent sheet.

When simply reading a part other than the paper piece to be copied, simply insert the opaque thin plate 3 with the black side up between the paper pieces, and see the printed surface free from dirt. it can. However, when the back surface is blank, the opaque thin plate 3 is used with the white surface facing up.

Even if a printed sheet using a highly transparent paper piece or an extremely thin paper piece is used, the use of the copy sheet of the present invention facilitates copying and browsing, so that the paper quality is not bothered. You can make cheap publications.

[0022] In order to create an unrestricted publication without being bound by the paper quality of the printed matter and the color of the printing ink, an opaque thin plate of the same color as the ink used for printing is used as a bookmark. It should be attached to things. By doing so, even if a printing ink having a special color tone is used, it is not necessary to sort out the colored transparent thin plate and measure complicated color adjustment, and copying and reading (referencing) are facilitated.

[0023]

By inserting the opaque thin plate 3 between the paper sheet 1 to be copied and the next paper sheet 2, most of the dirt on the surface to be copied is removed.

When the thing printed on the back surface 9 of the copy surface affects, the opaque thin plate 3 of the same color as the ink printed on the back surface is applied to the back surface 9 so that the space between the characters on the copy surface can be obtained. The reflected dirt can be removed.

From a plurality of colored transparent thin plates, an appropriate one
(2) By selecting two colored transparent thin plates 7 and overlapping them on the white surface 5 of the opaque thin plate, an opaque thin plate having the same color tone as the ink printed on the back surface 9 can be produced.
