Copying tack paper for thermal printer

Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Industrial application field]

The present invention relates to a copy tack paper for a thermal printer used for a thermal printer which is a data output device.

【0002】

[Conventional technology]

Conventionally, a thermal printer used in a data output device of a computer has a thermal head, and is configured to print by the heat of the thermal head.

【0003】

The paper used for the thermal printer includes a paper called 2P paper, which is shown in FIG. 3, and a tack paper, which is provided with an adhesive layer on the back surface as shown in FIG.

【0004】

Two sheets of thermal paper a and b are laminated on 2P paper, and when the two sheets of thermal paper a and b are separated after printing by the thermal head c, the two sheets of thermal paper a and b are printed respectively. As for the tack paper, a plurality of sheets of tack paper e are stuck on the mount d at regular intervals, and after printing with the thermal head c, the tack paper e is peeled off from the mount d and moved to another place. It is designed to be used by pasting it.

【0005】

On the other hand, on the above 2P paper, as shown in FIG. 5, two sheets of thermal papers a and b are stacked, and as shown in FIG. 6, a transfer ink made of carbon between the thermal paper f and the transfer paper g. Thermal paper with h-Some have adopted the transfer paper method.

【0006】

In the former 2P paper, which is a stack of two thermal papers a and b, when heat is applied to the upper thermal paper a with the thermal head c, the heat is transferred to the upper and lower thermal papers a and b, and both thermal papers are transferred. A and b are colored.

【0007】

In the latter 2P paper that adopts the thermal paper-transfer paper method, when heat is applied to the upper layer thermal paper f by the thermal head c, the upper layer thermal paper f develops color due to the heat, and at the same time, it is provided on the back surface of the thermal paper f. The transfer ink h is melted and transferred to the transfer paper g.

【0008】

On the other hand, as shown in FIG. 7, in the above-mentioned tack paper, a tack paper e made of thermal paper is adhered on the mount d via an adhesive layer i and a mold release agent j, and is printed on the tack paper e by a thermal head c. The rear tack paper e is peeled off from the mount d and attached to another place.

【0009】

[Problems to be Solved by the Invention]

The above-mentioned conventional 2P paper and tack paper are dedicated to each, and it is not possible to use 2P paper as tack paper and tack paper as ordinary copy paper.

【0010】

For this reason, when using tack paper as copy paper, it is necessary to print on the tack paper for the desired number of copies, which results in poor work efficiency, and when using 2P paper as tack paper, an adhesive is used after printing. There was a drawback that it had to be pasted.

【0011】

The present invention has been made to improve the above-mentioned drawbacks, and an object of the present invention is to provide a copy tack paper for a thermal printer that can be shared with a copy paper and a tack paper.

【0012】

[Means for solving problems]

In order to achieve the above object, the present invention (1) An adhesive is applied to a part of the back surface of the upper layer thermal paper, and this thermal paper is laminated and adhered to the lower layer thermal paper on which the release agent is applied on the upper surface at almost the same position as the above adhesive. Copy tack paper. (2) Apply an adhesive to a part of the back surface of the upper layer thermal paper, and bond this thermal paper on the middle layer thermal paper with the release agent applied on the upper surface at almost the same position as the above adhesive. At the same time, a copy tack paper obtained by applying an adhesive to the back surface of the above-mentioned middle layer thermal paper and adhering it to a mount on which a release agent is applied on the upper surface.

【0013】

[Action]

Since the copy paper and the tack paper can be shared by the above configuration, it is not necessary to prepare the copy paper and the tack paper separately, and the copy paper and the tack paper can be printed at the same time, so that the printing efficiency can be improved.

【0014】

[Example]

The first to second embodiments of the present invention will be described in detail with reference to the drawings shown in FIGS. 1 and 2.

【0015】

(A) and (b) of FIG. 1 show the first embodiment of the present invention, where 1 is a thermal paper, 2 is an adhesive, 3 is a mold release agent, and 4 is a thermal paper.

【0016】

On the back surface of the thermal paper 1 provided on the upper layer, the adhesive 2 is applied to the adhesive area 6 excluding the printed area 5 in the center, and the silicone-based release agent 3 is applied to a slightly wider area than the adhesive area 6. The lower layer thermal paper 4 is superposed via the pressure-sensitive adhesive 2 and the release agent 3.

【0017】

The adhesive region 6 does not have to be provided on the entire periphery of the print region 5, and may be provided only on the top and bottom or left and right.

【0018】

When printing is performed on the print area 5 of the copy tack paper of the first embodiment configured above with a thermal head, heat is transferred from the upper layer thermal paper 1 to the lower layer thermal paper 4, and both thermal papers 1 and 4 develop color. However, it is possible to print on both thermal papers 1 and 4.

【0019】

When the two printed thermal papers 1 and 4 are peeled off from the boundary between the adhesive 2 and the mold release agent 3, the upper thermal paper 1 can be used as a tack paper because the adhesive 2 is applied to the back surface, and the lower layer can be used. The thermal paper 4 can be used as a copy paper.

【0024】

Further, (a) and (b) of FIG. 2 show a second embodiment of the present invention, in which 20 is a thermal paper, 21 is an adhesive, 22 is a mold release agent, 23 is a thermal paper, and 24 is an adhesive. 25 indicates a mold release agent, and 26 indicates a mount.

【0025】

On the back surface of the thermal paper 20 provided on the upper layer, the adhesive 21 and the mold release agent 22 are applied to the adhesive region 28 excluding the printing area 27, and the heat sensitivity of the middle layer is applied through the adhesive 21 and the mold release agent 22. Paper 23 is piled up.

【0026】

Then, the adhesive 24 is applied to the entire back surface of the middle layer thermal paper 23, and the adhesive 24 causes the upper and middle layers thermal papers 20 and 23 to be placed on the mount 26 to which the release agent 25 is applied on the upper surface. It is glued.

【0027】

When printing is performed on the printing area 27 of the copy tack paper of the second embodiment configured above with the thermal head, the upper and middle layers of the thermal papers 20 and 23 are colored and printed.

【0028】

Further, the upper layer thermal paper 20 can be used as a tack paper by peeling from the boundary between the pressure-sensitive adhesive 21 and the release agent 22, and the middle layer heat-sensitive paper 23 can also be peeled off from the boundary between the pressure-sensitive adhesive 24 and the release agent 25. Can be used as tack paper.

[Effect of the invention]

According to the first embodiment of the present invention, since the upper layer thermal paper can be used as a tack paper and the lower layer thermal paper can be used as a copy paper, it can be shared with the copy paper and the tack paper, and can be used as a conventional tack paper. There is no need to print the required number of sheets to obtain a copy, or to apply adhesive to the back side of the copy paper after printing and use it as tack paper.

【0035】

【0036】

On the other hand, according to the second embodiment, since two sheets of tack paper can be printed at the same time, the required number of printed tack papers can be obtained in half the printing time as compared with the case of printing on the conventional tack paper. It is efficient.
