JPH0467043A - Erasable paper - Google Patents

Abstract

PURPOSE:To easily make a distinction from normal paper by carrying out a peeling process for the surface of a sheet type base and making a display which shows that the sheet is erasable. CONSTITUTION:The peeling process 103 is carried out for the surface of the sheet type base 101 and the display 102 which shows that the sheet is erasable paper is made. In this case, when the erasable paper is distributed widely in the word, the paper is not thrown away because of the presence of the display and the paper is cleaned by a cleaning device and used repeatedly. Thus, the display showing that the erasable paper is provided to make an easy distinction from the erasable paper, thereby decreasing the consumption of paper.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to paper used in printers and copying machines, and particularly to eraser pull paper C which can be used by cleaning and recycling used paper.

BACKGROUND OF THE INVENTION With the advent of office automation in recent years, printer paper and copy paper have come to be used in large quantities. This has even led to the problem of deterioration of the global environment due to deforestation. Conventionally, the only way to solve this problem was to remove the ink, etc. from used paper, crush it, and throw it out again to recycle it into what is called waste paper. However, recently, a cleaning method has been developed that easily removes the character images on used paper. For details, please refer to the patent application 1986-1.
No. 28946. According to this invention, an eraser pull paper whose surface has been subjected to a mold release treatment is used, and then ζ-printing is performed on the paper, and then, for cleaning, a molten paper is applied on top of the printing. It is coated with 7g of fusible material (cleaning material), cooled, and the printed text and images are removed along with the hot-fusible material.

This method is very effective; the paper that has undergone release treatment can be used hundreds of times, and by making the printing ink thermofusible and the same material as the cleaning material, the cleaning material can also be used hundreds of times. It can be used. Therefore, it is very economical and of course does not destroy forests.

Problems to be Solved by the Invention However, since the eraser pull paper is difficult to distinguish from plain paper, it may be thrown away together with the plain paper or torn. Another problem is that if plain paper is treated as eraser pull paper and is applied to the cleaning device, the cleaning material will stick and cannot be removed.

Means for Solving the Problems In order to solve the above problems, in the present invention, the surface of the sheet-like support is subjected to a release treatment to indicate that it is an erasable paper.

Function Even though the eraser pull paper of the present invention is widely distributed in society,
Because it has a label, you can use it many times by putting it in a cleaning device without having to throw it away.

This can greatly reduce paper consumption.

EXAMPLES Hereinafter, the eraser pull paper of the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a sectional view of an example of the eraser pull paper of the present invention, and 101 is a support. Materials include plastic sheets and paper. 102 is a mark indicating that it is erasable, and is attached by printing, etc. 103 is a release layer, which adjusts the adhesion of ink and toner for letters and images placed on it, and is used for cleaning as will be explained later. It should be easy to remove during processing, and should not come off during normal handling.

Eraser-pull paper made in this way can be distinguished from regular plain paper because it has markings, and can be recognized by a machine and automatically separated if mixed.

Although FIG. 1 shows a mark indicating that it is erasable before the mold release process, this is not necessarily necessary and it is also possible to mark the mark after the process. It is also possible to print on the back side. Alternatively, it can also be displayed by making a hole.

Of course, it is easy to perform mold release treatment on both sides of the support. It can also be displayed.

Example 1 Mark an A4 size coated paper with a marker and apply a silicone sticker (manufactured by Toshiba Silicone, product name: TSE) on top of it.
397) was applied thinly and dried to make eraser pull paper. This eraser pull paper can be used as paper in a copying machine (
When I printed on Canon's FC-511), I got an image that was almost the same as a copy on plain paper. The image side of this eraser pull paper is laminated with a film pack (TOLAM I-F I manufactured by TOKYO LAMIYO/KUS Co., Ltd.).
LM(A)) on the coated surface of the heat-melting resin, and laminated with laminations (manufactured by Tokyo Laminenox Co., Ltd., LPD).
-2301), the eraser pull paper and the laminate film were (plucked and integrated). When I peeled it off when it was cool, it peeled off easily, and the image toner was peeled off from the surface of the eraser pull paper, making it impossible to clean. However, the marks made with a marker did not disappear and were easily distinguishable from ordinary paper.

Example 2 Mark plain paper (copy paper) with a pencil and apply mending tape (manufactured by Sumitomo 3M Ltd. 8110) on top of it.
) and made eraser pull paper. An image was formed by copying the same camphor as in Example 1 on this eraser pull paper, and the same cleaning treatment was performed thereafter. As a result, the image was removed. However, the pencil marks remained and were easily distinguishable from regular paper.

Example 3 Mending tape (manufactured by Sumitomo 3M Ltd. 81)
The liner from 10) was cut into A4 size and a small hole was punched in the corner to serve as a mark. This liner was used as eraser pull paper, and a copy was made on the release layer side in the same manner as in the example.

The toner had good adhesion and did not come off even by rubbing it with my fingers. When I applied a cleaning process (erase process) to this, it peeled off cleanly and returned to a state where it could be used for copying. Since there are holes in the corners, there is no need to mistake the release surface.
It was easy to distinguish it from well-laid paper that had not been subjected to release treatment.

Effects of the Invention By using the present invention, since there is a display indicating that the paper is erasable, it can be easily distinguished as eraser pull paper, and it can also be sorted by machine.
