JPH0538893A - Method for binding slips coated with color developing chemical and the same slip - Google Patents

Abstract

PURPOSE:To provide slips which prevent the fingers and papers from staining and avoid the use of ink ribbon. CONSTITUTION:The slips 3 arranged in bound form are composed of some sheets of paper, each having one side 1 coated with a chemical adapted to produce a color on the paper surface upon applying a force thereto, and fastened together, so that the chemical-coated side 1 will become a rear face 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention uses a paper coated with a chemical that develops a color when a force is applied to the surface, with the surface being the back surface.
The present invention relates to a method for forming a slip by binding several sheets of paper and binding the slip.

[0002]

2. Description of the Related Art Conventionally, back carbon and non-carbon paper have been used for slips and the like. In addition, in a commercially available paper coated with a chemical that develops color when a force is applied to it, another paper, such as high-quality paper, is placed on the surface (upper surface) of the paper coated with the chemical. There was a method to copy the characters etc. written on the high quality paper.

[0003]

Problems to be Solved by the Invention In the conventional slips using back carbon, when handling slips, the hands become dirty,
The paper had the drawback of becoming dirty.

Also, in the case of conventional non-carbon paper, especially in the case of non-carbon paper used for slips in which certain items are written using a machine, the first paper on the top is normal paper. There is a drawback that an ink ribbon is required, and when the ink ribbon is cut, it becomes thin and is not printed, making it unreadable.

Then, when another paper is used by overlapping it on the surface of a paper coated with a chemical which develops a color when a conventional force is applied, the hand is soiled as in the case of using the back carbon,
It had the drawback of soiling the paper. Furthermore, the front surface (upper surface) coated with the chemical is not used for the back surface (lower surface), nor is it used for a slip.

In view of the above, the present invention uses a front surface of paper coated with a chemical that develops color when a force is applied to the back surface, so that the hands and the paper are not soiled. It is an object of the present invention to provide a method for creating a slip that does not require an ink ribbon as in the case of using the slip and the slip.

[0007]

In order to achieve the above object, the method of making a voucher according to the present invention uses the above-mentioned paper with the front surface of a paper coated with a chemical that develops color when a force is applied to the front surface. This is a method of creating a slip that stacks several sheets.

Further, the voucher according to the present invention is formed by binding several sheets of paper, with the front surface of a paper coated with a chemical that develops a color when a force is applied to the front surface being the back surface.

It is more effective that the slip is a sales card of a credit card and that the paper is transparent.

[0010]

[Function] As mentioned above, with the surface of the paper coated with the chemical that develops color when pressure is applied to the back side, several sheets are stacked and bound, and pressure is applied by hand from above to remove letters, symbols, etc. If you write it, since the part that develops color is on the back side of the paper, the surface on which the letters, symbols, etc. are written does not get dirty by hand, and the same letters, symbols, etc. will be reflected on many sheets of paper below. .

In addition, when a character is applied by a machine to write characters, symbols, etc., since the first color on the back side of the paper is coated with a coloring agent, the characters, symbols, etc. on the back side are reflected on the front side. Since there is no need to use an ink ribbon as with non-carbon paper, it is convenient and inexpensive.

When the machine is used, it is preferable that the slip is a sales slip of a credit card and the paper is transparent. Because the paper is transparent, the letters, symbols, etc. on the back side are also reflected on the front side.

[0013]

EXAMPLES Examples will be described with reference to the drawings. FIG. 1 shows a slip 3 of the present invention, in which a paper coated with a chemical that develops color when a force is applied is used and the front surface coated with the chemical is used as a back surface 2. And
When force is applied by hand or machine from above, the letters will appear on the paper below.

FIG. 2 is a diagram showing an embodiment in the case of using the slip of the present invention by using a machine. When the machine 4 is used to write characters, symbols, or the like on the slip 3 of the present invention, it is preferable that the paper is transparent and the sales slip of a credit card.

When the voucher 3 of the present invention is placed at a predetermined position on the machine 4 and the lever 5 is pushed, characters, symbols and the like are printed on the front surface 1 of the paper, and characters and symbols are printed on all the sheets of the voucher. Will be done.

[0016]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it does not stain hands or paper and does not use an ink ribbon like non-carbon paper. It is convenient and inexpensive.
