Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roll paper for a thermal printer used when issuing a receipt at a supermarket cash register, taxi or the like.
[0002]
[Prior art]
Normally, when issuing a receipt at a supermarket cashier or taxi, set the thermal paper in the thermal printer provided, and transport the end of the thermal paper between the thermal head and the platen roller to print the specified information. Is doing.
[0003]
As the thermal paper, in consideration of handling, a roll-shaped paper is usually used as shown in FIG. That is, the roll paper 1 for the thermal printer has a configuration in which the thermal paper 3 is wound around the core 2 in a roll shape, and the paper edge 3a is fixed by the stopper 4 so that the thermal paper 3 is not loosened.
[0004]
[Problems to be solved by the invention]
However, when the conventional roll paper 1 is loaded into the thermal printer, first, the stopper 4 is peeled off, the roll paper 1 is set in a loading unit of a printer device (not shown), and the paper end 3a of the thermal paper 3 is used as a thermal head. Although it is inserted and positioned between the platen roller and the adhesive, the adhesive of the stop seal 4 remains on the surface of the thermal paper 3, so that the user actually cuts off one round of the thermal paper for use.
[0005]
Therefore, one round of paper from the paper edge 3a of the thermal paper 3 is wasted, resulting in material loss of the thermal paper 3, and accompanied by the troublesome work of cutting off the thermal paper 3, and improving the workability in the roll paper 1 setting work. At the same time, it was pointed out the disadvantage of lowering.
[0006]
In addition, since one round of paper becomes trash, the trash disposal work is troublesome, and this tendency is particularly remarkable in a car such as a taxi.
[0007]
The present invention has been made in view of such circumstances, and in the thermal printer roll paper supplied to the thermal printer, the thermal paper is effectively used by preventing the adhesive of the stop seal from remaining on the surface of the thermal paper. Another object of the present invention is to provide a roll paper for a thermal printer that can simplify dust disposal and can be easily set in a printer.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a thermal printer roll paper in which thermal paper is wound in a roll shape and the paper end is fixed by a sticker seal. It is characterized by being printed with ink.
[0009]
Here, the roll paper is a thermal paper wound in a roll shape, and this thermal paper is printed with predetermined information in addition to the frame line, ruled line, etc., and after the printing process, as a single piece receipt In order to issue, perforations are formed at predetermined intervals along the longitudinal direction of the thermal paper.
[0010]
In addition, as the thermal paper, a thermosensitive recording medium in which an electron donor such as a leuco dye (colorless) in a binder applied to a base paper and an electron acceptor such as phenol react with heat to develop color. use.
[0011]
Usually, a colorless leuco dye (electron donor), such as crystal violet lactone, and an acidic substance (electron acceptor), such as bisphenol A, are dispersed in a resin binder and coated on paper to form a heat-sensitive recording layer. It is formed.
[0012]
Next, as colorless transparent ink that is printed on the surface of the thermal paper at the place where the sticker seal is applied, trade name: Hakuri OP Varnish UP-2, RNC Medium (manufactured by T & K TOKA) is used, and the sticker seal does not peel off. In order to achieve this, the printing amount of the transparent ink is controlled by solid printing, or halftone printing (halftone dot area ratio of 10 to 80%) is performed.
[0013]
As is clear from the above configuration, the surface of the thermal paper that is attached to the sticker seal is printed with transparent ink so that the adhesive of the sticker seal does not remain on the thermal paper surface. It is not necessary to cut and remove one round from the beginning, and the stopper seal can be easily peeled off, and the paper edge can be set easily.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a roll paper for a thermal printer according to the present invention will be described in detail with reference to the accompanying drawings.
[0015]
FIG. 1 is an external view of a roll paper for a thermal printer according to the present invention, and FIG. 2 is a cross-sectional view showing the configuration of the roll paper.
[0016]
In FIG. 1, a thermal printer roll paper 10 has a thermal paper 12 wound around a core 11 in a roll shape. The paper end 12a of the thermal paper 12 is fixed to prevent the paper 12 from coming loose. It is fixed by.
[0017]
More specifically, the thermal paper 12 has a thermal recording layer on the surface of the base paper, in which an electron donor such as leuco dye (colorless) and an electron acceptor such as phenol react with heat to form a color. Yes.
[0018]
Since the thermal paper 12 is cut into predetermined dimensions and issued as a single-piece receipt, perforations are formed at predetermined intervals, and predetermined information such as frame lines, ruled lines, and user names are printed. Has been processed.
[0019]
By the way, the feature of the present invention is to eliminate the waste of the thermal printer roll paper 10 and to easily perform the setting operation to the printer.
[0020]
That is, a printing layer 14 of colorless transparent ink is formed on the sticking surface of the stop seal 13 on the thermal paper 10 so that the adhesive of the stop seal 13 does not remain.
[0021]
As the transparent ink, in this embodiment, trade name: Hakuri OP varnish UP-2, RNC medium (manufactured by T & K TOKA) is used, and in order to prevent the stopper seal 13 from being peeled off, a colorless transparent ink is used. Control is preferably performed by halftone printing (halftone dot area ratio of 10 to 80%), or printing in which the amount of ink deposited by solid printing is controlled.
[0022]
That is, the printing layer 14 performs a printing process with colorless transparent ink from the paper end 12a of the thermal paper 12 to a length slightly longer than the length of one round.
[0023]
In addition, it can apply also to the roll paper 10 which does not have the winding core 11 by product specification.
[0024]
Since the roll paper 10 for a thermal printer according to the present invention is configured as described above, for example, when the user sets the roll paper 10 in the thermal printer, the roll paper 10 is removed after removing the stop seal 13. At this time, the printing layer 14 is formed on the thermal paper 12 where the stop seal 13 is applied. Therefore, the stop seal 13 can be easily peeled off, and the stop seal 13 is peeled off. Since the rolled paper 10 is loaded into a predetermined portion of the printer and the paper end 12a of the thermal paper 12 is inserted between the thermal head and the platen roller, the thermal paper is wasted for one turn as in the prior art. In addition, there is no waste of paper, and there is no work for cutting out one turn, and the setting work can be simplified.
[0025]
In addition, since no waste is generated for one round of paper, the conventional waste disposal is unnecessary, and this is particularly suitable in a car such as a taxi.
[0026]
【The invention's effect】
As described above, the present invention has the special effects described below.
[0027]
(1) Since the roll paper for a thermal printer according to the present invention is printed with colorless transparent ink on the surface of the thermal paper at the place where the sticker for fixing the paper end of the thermal paper is fixed, the sticker is attached to the thermal paper. This eliminates the need to cut out one round of thermal paper as in the past, eliminates paper waste, enables effective use of materials, and suppresses the generation of dust. This has the effect of simplifying the waste disposal work.
[0028]
(2) Since the roll paper for a thermal printer according to the present invention has a configuration in which a printing process is performed with colorless transparent ink on the surface of the thermal paper at the location where the paper sticker for fixing the paper is fixed, the peeling of the paper sticker is peeled off. Operation is easy, and the end of the thermal paper only needs to be inserted between the thermal head and the platen roller. Has the effect of improving.
