Abstract

PURPOSE:To ensure secrecy and to utilize paper resources by using copy forms whose copy contents can be erased and recopied physically and chemically, and providing an erasing and a form reproducing process. CONSTITUTION:A copy form 1 consists of a copy form base 2, a coating layer 3 in which copies characters, graphic forms, etc., are erasable by physical or chemical processing, and a solvent prevention layer 4 which serves as a conduction processing layer. A copy to the copy form 1 is taken by a copying machine 9. At this time, copy characters, graphic forms, etc., are copied to the copy form 1A so that they are erased by the physical or chemical processing. When the copied form 1A is not necessary any more, the copied characters, graphic forms, etc., are erased in an erasing process 14. The copy form 1 is formed in a copy form forming process 16 so that the erased form 1B can be recopied, and consequently the copy is used in a cycle state. Thus, the copy form is reused, the copied characters, graphic forms, etc., are erased by the physical or chemical processing, and its secrecy is ensured completely.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying method in which a copy once copied can be erased and copied again, and a reusable copy paper used in the copying method.

Traditionally, copied documents are thrown away when they are no longer needed, or confidential documents are destroyed or shredded.
It was cut into small pieces and processed.

For this reason, there is a drawback that destroying confidential documents requires time and effort and wastes paper resources. In addition, it is possible to reuse items that are related to secrets by processing them with a shikoretsudar, but it is also possible to recreate them by piecing them together, so please be careful when disposing of them as waste paper. There was a drawback that it had to be done.

In view of the above-mentioned conventional drawbacks, the present invention aims to maintain confidentiality by erasing the copied characters, figures, etc. when a copy of a confidential document is no longer needed, and also reuses the erased copy paper. To obtain a copying method and reusable copying paper used in the copying method.

Hereinafter, the present invention will be explained in detail with reference to the drawings and embodiments.

In the embodiments shown in FIGS. 1 to 6, 1 is copy paper, and this copy paper 1 is shown in FIG. After that, J
The coating layer 3 is composed of a coating layer 3 that can erase printed characters, figures, etc., and a conductive treatment layer 11) and a solvent prevention layer 4 coated on the back side of the copy paper main body 2. As shown in FIG. 2, there is a conductive treatment layer 5 coated on the surface of the copy paper main body 2, a polymer binder layer 6 coated on the surface of the conductive treatment layer 5, and a polymer binder layer 6 coated on the surface of the conductive treatment layer 5. It is composed of a toner binder layer 7 applied to the surface.

8 is a copying step in which the copying paper 1 is copied by a copying machine 9, and characters 10, figures 11, etc. copied in the copying paper 1A copied in this copying step 8 are erased by physical and chemical processing. Possible state C has been copied. Reference numeral 12 denotes a recycling process in which when the copied paper 1A is no longer needed, the copied characters 10, figures 11, etc. are erased and recycled into a reusable copy paper 1. Paper 1 copied in step 8
Physical or chemical treatment of copied letters 10, figures 11, etc. of △ (for example, Xerox correction fluid (product name: Fuji Xerox))
Erasing step 1 of passing through the erasing surface 13 to erase the copied characters and figures etc. using the Art Clear A7 Erasing Correct Ben (product name: Platinum Fountain Pen Co., Ltd.)
4, and after recopying the paper 1B as shown in FIG. 5, which was created by erasing the copied characters 10, figures 11, etc. in this erasing step 14, the characters 1 copied by physical and chemical treatment.
The copy paper making step 16 consists of a reproduction step 16 in which the previously blanked copy paper 1 is passed through a reproduction hole 15 so that zeros, figures 11, etc. can be erased.

The erasing step 14 is no longer necessary as shown in FIG.
A step 18 of collecting and aligning the copied sheets 1A on the master tongue table 17, and this master tongue table 1.
Erasing processing step 2 in which the copied sheets 1A aligned in 7 are sent one by one to the processing section and the copied characters, figures, etc. are processed and erased by the physical and chemical processing section 19.
0, and a step 22 in which the reusable sheets 1B that have been erased in the DJ removal process 20 and made available for reuse are collected in the stacking section 2 and arranged so as to be packed.

Further, the copy paper making process 1G includes a step 24 of collecting and aligning the recycled 111 mm 11"t into the pre-processing section 23 of @15 as shown in FIG. A coating process 26 in which the sheets of paper 1B are sent one by one to a processing section 25 and a polymer binder layer 6 and a toner binder layer 7 are coated on the surface, and the copy paper 1 formed in this coating process 26 is transferred to a stacking section 27. The process consists of a step 28 of collecting the items and arranging them so that they can be carried back.

In the above configuration, copies are made on the copy paper 1 by the copy machine 9. At this time, copy character 1 of copied paper 1A
0, figure 11, etc. are copied in a state where they can be erased by physical or chemical treatment. Next, when the copied paper 1A is no longer needed, it is copied in the erasing step 14! ζ Erase characters 10, figures 11, etc. Further, by creating the copy paper 1 in the copy paper production step 16 so that the paper 1B on which the characters 10, figures 11, etc. have been erased can be copied again, copying can be used in a cyclical manner.

Next, different embodiments of the present invention shown in FIGS. 7 and 8 will be described. In addition, in explaining these examples,
The same parts as those in the embodiment of the present invention are given the same reference numerals and redundant explanations will be omitted.

The main difference between the embodiment J3 in FIG. 7 and the embodiment of the present invention described above is that the reproduction step 12A is erased in steps 14 and 14, and even in this way, the blank paper 1B It can be reused as memo paper or other paper, and the secret of the copy can be completely protected.

The main difference between the embodiment shown in FIG. 8 and the previous embodiment is that it can erase characters, figures, etc. copied onto blank copy paper 1A by physical or chemical processing, such as a check pen (product name: Pibra Co., Ltd.). ) Copying machine 9 onto paper 1a using ink or paint, etc.
In addition to making the copy process 8A, which can be copied using A, the copied characters and figures can be erased with erasable ink or paint, such as that used in the Eraser Pen (trade name: Zebra Co., Ltd.), etc., to create copy paper. The same effect can be obtained even when drawn in this manner, in that the reproduction step 12B is used to reproduce the paper 1a (blank paper).

As is clear from the above description, the present invention has the following effects.

(1) Copy paper can be reused after it has been used for copying. Therefore, it is descriptive.

(2) Physically copy characters and figures etc. onto copy paper.
Since it can be erased by chemical treatment, it can be completely kept secret.

(3) After making a copy, you can erase the copied characters and figures and reuse it as memo paper or other paper.Since all copy paper can be reused, the cost of copying can be reduced to 1. can.

(4) In addition to the conventional copying process, copying can be done in cycles by erasing and reproducing copied characters and figures, so the process is simple and anyone can use it. It is.
