JPS61248785A - Recording paper for facsimile - Google Patents

Abstract

PURPOSE:To enhance the secrecy of facsimile communication, by constituting the titled recording paper from a transparent base material, the opaque cover member covering at least a part of one surface of the base material and provided in a releasable manner, the color forming layer provided on the other surface of the base material and forming a color under heating and the opaque layer applied to the color forming layer. CONSTITUTION:Thermal recording paper 1 is constituted of a transparent base material 2, the cover member 3 partially adhered to one surface of the base material and provided in a releasable manner, the color forming layer 4 provided to the other surface of the base material 2 and the opaque layer 5 applied to the surface of the color forming layer 4. Recording is performed by contacting a thermal head 6, of which the leading end is heated, with the recording paper from the side of the opaque layer 5 and transmitting heat to the color forming layer through the opaque layer 5 to allow the color forming layer 4 to develop a color. The character or drawing generated by color development is covered with the opaque layer 5 and not read from the side of the opaque layer 5 but can be read from the side of the opaque layer 5 by peeling off the cover member 5. As far as the cover member is not released, content can be kept secret.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to facsimile recording paper, and more particularly to facsimile recording paper configured so that its contents cannot be viewed from the outside.

Fax machines are very convenient as they can instantly send documents and drawings to long distances, but since the documents being sent are easily visible from the outside, they are not suitable for sending documents that you only want to show to specific people. . In recent years, there has been a service called confidential fax that allows sending information to be stored on a computer and retrieved using a specific code. This method requires a lot of effort and is not suitable for people who are busy because they have to input and withdraw the code themselves each time.

The present invention relates to facsimile recording paper that has a cover member provided on the recording surface of the facsimile recording paper so that the contents of sent information cannot be seen from the outside unless the cover is removed. This will be explained below along with the drawings.

The thermal recording paper 1 according to the present invention includes a transparent base material 2 and a base material 2.
a cover member 3 partially adhered to and removably provided on one surface of the base material 2; a coloring layer 4 provided on the other surface of the base material 2; and an opaque material coated on the surface of the coloring layer 4. It is composed of layer 5.

In recording, a thermal head 6 whose tip is heated hits the recording paper 1 from the side of the opaque layer 5, and heat is transferred to the coloring layer 4 through the opaque layer 5, thereby causing the coloring layer 4 to develop color. The characters and drawings generated by this coloring are covered with the opaque JI 5 and cannot be read from the side of the opaque layer 5, but by peeling off the cover member 3, they can be read from the side of the transparent base material 2, and the base material 2 becomes transparent. It can be made of any material such as plastic, paper, etc. Further, the opaque layer 5 may be any material that does not cover the color of the coloring layer, such as opaque paint.

If you use facsimile recording paper configured in this way,
Documents and images sent to us are covered with a cover material,
The contents can be kept secret unless the cover member is removed. By displaying the addressee in the part that is not covered by the cover, facsimile communications, which traditionally had less confidentiality than letters, can be handed over to the recipient and opened by that person just like a letter. This has the excellent effect of increasing confidentiality.
