DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a thermal printer of a handy terminal used for out-of-office work such as meter reading and collecting money, and is issued at the time of transfer paper requiring high-precision printing or at the time of collecting money. The present invention relates to thermal printer paper that can issue books of various different formats such as a receipt requiring a sealability using the same printer.

[0002]

2. Description of the Related Art In recent years, handy terminals for printing the results on site in office work such as meter reading and collecting money have been widely used. The handy terminal prints the results of work outside the office, such as meter reading and collection, as a notice slip, a receipt for automatic debit of the usage fee from the bank account, etc. at the site, and separates the print result and passes it to the user. In a conventional handy terminal, for example, the usage amount of electric power or the like is measured, and the result is printed on site. However, the pattern of the print format is limited to only the pattern indicating the result of the meter reading. For this reason, the meter reading results are automatically entered into a predetermined pattern and printed, and the printer paper used for the printing is in a print format that informs the meter reading results. A single handy terminal can produce various forms such as transfer paper that require high-precision print position accuracy on the premise of data processing by an OCR reader or the like.
It was not possible to deal with the type of printer paper.

[0003] Thermal printer paper is a recording medium in which a recording image is formed by reacting a coloring agent in the thermal recording layer by heating the thermal recording layer with a thermal head or a thermal pen of the thermal printer. In addition, the weather resistance and chemical resistance of the recorded image are essentially not sufficient, and there is a disadvantage that the recorded image is discolored and the background is covered. Conventionally, in order to improve the problem of the thermosensitive recording medium, by providing an overcoat layer on the thermosensitive recording layer, the weather resistance and chemical resistance of the recorded image are improved, and the fading or the recorded image is reduced. Reduces scalp coverage. In addition, the UV-curable resin layer improves the conventional thermosensitive recording medium by eliminating the disadvantage that when wet with water, the thermosensitive recording layer becomes tacky and sticks to other recording media or paper stacked on it. However, because of the function of preventing the penetration of the ink or the like of the ultraviolet-curable resin, it has been difficult to use it for a receipt that is required to be imprinted during collection of money.

[0004] For this reason, to a user who has not made a contract for automatic debit from a bank account, administrative procedures for sending a transfer notice and a transfer request form for requesting a usage fee, and a reminder to pay the fee. It takes a lot of time and money to send out the letter shipping, and as a result, it is one of the factors that increase the usage fee. In addition, in the collection business such as broadcast reception fees and newspaper charges, the necessary items are filled in and stamped on books of various different formats such as receipts issued at the time of collection, and handed to the user. In addition, it is necessary to prepare books and books of different formats in advance, and there is a problem that the collection operation becomes complicated.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is an explanatory view showing the configuration of a thermal printer sheet according to the present invention. In FIG. 1, (a) shows the front side of a printer paper for a thermal printer on which a postal transfer-only transfer note is printed, and (b) shows the back side thereof. In FIG. 1A, P1 is an area where the first vote of the postal transfer transfer is printed, and P2 is an area where the second vote of the postal transfer is printed. Region P1 and region P
2, a print pattern of one postal transfer note is formed. M is a perforation provided at the boundary of each print pattern in order to easily separate the printed postal transfer transfer note. m denotes an area P1 and an area P1 to make it easy to separate the area P1 where the data of the first vote is printed from the area P2 where the data of the second vote of the printed postal transfer dedicated transfer note is printed. It is a perforation inserted between P2.

In FIG. 1B, dt1 and dt2 are eye marks for print positioning. The eye marks dt1 and dt2 are eye marks for positioning the area P1 on which the data of the first vote and the area P2 on which the data of the second vote of the postal transfer-only transfer note are printed. In addition, dt3 is an eye mark used for cueing the transfer note dedicated to postal transfer and positioning for printing a notice sheet of the meter reading result of the integrating meter indicating the usage amount of gas, water, electric power, and the like. The thermal printer sends out the paper when printing the format and data of the postal transfer transfer document, and stops the print paper when detecting the eye mark for dt1 print positioning in FIG. 1B. Then, the print position of the area P1 where the data of the first vote is printed is determined, and the format and the data are printed at the same time. After printing the area P1, the thermal printer performs dt2 of FIG.
When the eye mark for print positioning is detected, the printing paper is stopped, the print positioning of the area P2 where the data of the second vote is printed is performed, and the format and the data are printed simultaneously. After printing the area P2, when the thermal printer detects the dt3 eye mark in FIG. 1B, it stops the print paper and positions the head for printing the next print pattern.

In this manner, the print position of the first vote of the transfer note is determined by the eye mark dt1 for positioning the first vote of the transfer note, and the eye mark dt1 for positioning the second vote of the transfer note is perforated. m right after this m
By determining the print position of the second vote by detecting t2, the writing accuracy can be improved. In addition, an eye mark dt3 is provided at a position after the transfer letter for cueing the next print so as to prepare for the next print. The eye marks dt1, dt2, dt3 are
By changing the width, the function of the mark can be identified. Specifically, the eye mark dt1 is set to 2 mm ± 0.1 in width. The eye mark dt2 is set to 5 mm ± 0.1 in width. The eye mark dt3 is set to 3 mm ± 0.1 in width. Can be identified.

The use of the three types of eye marks makes it possible to accurately print the format and data of a postal transfer-only transfer note having two different data areas using a thermal printer. FIGS. 2, 3, and 4 respectively show a transfer handling form based on the postal transfer private transfer standard, a transfer form, and a positional relation standard of the transfer form and the transfer form. The postal transfer-dedicated transfer form is composed of a first transfer form consisting of an account number field, an amount field and a subscriber name field as shown in FIG. 2, and a second transfer form and receipt form shown in FIG. The transfer slip is a perforation, and a perforation is provided between the transfer handling slip and the transfer slip, and the positional relationship is strictly defined as shown in FIG. That is, as shown in FIG. 2, the left-hand perforation of the transfer handling slip must be within 4 mm and 0.3 mm from the left vertical line in the account number column. Similarly, the position of the printing position alignment frame of the second transfer slip is strictly determined based on the left side of the transfer handling slip as shown in FIG.

By providing unique eye marks as shown in FIG. 1 (b), it is possible to cope with such a strict standard by using a thermal printer having low print positioning accuracy. Was. In this case,
The accuracy of the position of the postal transfer document printed by the thermal printer is affected by the accuracy of the positional relationship between the perforations and the eye marks, which is set in advance on the thermal printer paper. For this reason, the processing precision between the printing of each eye mark and the perforation and the printing of the eye mark,
It is necessary to be ± 0.2 mm (preferably ± 0.2 mm or less), but this accuracy can be achieved by adjusting the printing machine for the eye mark.

Next, the configuration of the recording surface on the surface of the printer paper of the present invention will be described. Thermal printer paper is a recording medium in which a recording image is formed by heating the heat-sensitive recording layer with a thermal head or a hot pen of a thermal printer to react with a coloring agent in the heat-sensitive recording layer. In general, the recorded image has insufficient weather resistance and chemical resistance, and has a disadvantage that the recorded image is discolored and the background is covered.
Conventionally, in order to improve the problem of the thermosensitive recording medium, by providing an overcoat layer on the thermosensitive recording layer, the weather resistance and chemical resistance of the recorded image are improved, and the fading or the recorded image is reduced. The scalp coverage is reduced. further,
With the UV-curable resin layer, the conventional heat-sensitive recording medium has been improved in that the heat-sensitive recording layer becomes tacky when wet with water and sticks to another recording medium or paper superposed on the heat-sensitive recording layer. However, due to the function of the protective layer of the UV-curable resin to prevent the penetration of moisture such as ink, it has been difficult to issue a receipt that is required to be imprinted during collection.

In the thermal printer paper of the present invention, the uppermost UV-curable resin protective layer provided on the heat-sensitive recording layer containing the color former provided on the surface of the support is laminated except for the marking portion. Thus, it is possible to print a receipt or the like that requires a sealability. FIG. 5 is an explanatory diagram showing the configuration of printer paper used in the thermal printer of the present invention, and shows an example of a transfer receipt exclusively for postal transfer. In FIG. 5, (a) shows the surface of the thermal printer paper on which the postal transfer exclusive transfer note is printed,
(B) shows the back surface. 5A and 5B, reference numeral 10 denotes an ultraviolet-curable resin layer provided on the thermal recording layer on the surface of the thermal printer paper, 11 denotes a portion of a seal or the like from which the resin layer is removed, and 12 denotes an eye mark. is there. The resin layer 10 on the front surface of the thermal printer paper is
By using letterpress printing or the like with reference to the printing position, the positional relationship between the position of the eye mark 12 and the portion 11 such as a seal where the resin layer is removed is always kept constant. For this reason, even when the thermal printer prints a receipt or the like requiring the sealability based on the eye mark 12, the portion 11 such as the seal is always reliably printed on the portion where the resin layer is removed. I can do it.

Next, a description will be given of the structure of a thermal paper recording layer suitable for use in the handy terminal printer paper of the present invention. The heat-sensitive paper recording layer of the handy terminal printer paper of the present invention has, on the heat-sensitive layer, printability and writability of shachihata ink and vermilion, improves the weather resistance and chemical resistance of the recorded image, and fades the recorded image. Alternatively, an overcoat layer is provided to reduce background fogging, and on this overcoat layer, as shown in FIG. 5, the uppermost layer of an ultraviolet-curing type for preventing blocking, head residue and stitching except for a stamped portion. It is configured to provide the resin layer 10. The overcoat layer contains, in the layer, at least amorphous silica as a pigment, carboxy-modified polyvinyl alcohol as an adhesive, and a crosslinking agent,
The carboxy-modified polyvinyl alcohol is contained in an amount of 0.5 to 2 parts by weight based on 1 part by weight of the pigment. When the surface strength of the layer is reduced, offset printing, UV printing, etc. is performed on the overcoat layer surface, or when the uppermost layer is formed by a printing machine or a coating machine, or during recording, piling occurs and uniform printing is performed. If the uppermost layer is not obtained, and if the carboxy-modified polyvinyl alcohol exceeds 2 parts by weight, the printability of the overcoat layer on which the uppermost layer is not formed may be significantly reduced. Particularly preferred.

The amount of the amorphous silica used is preferably about 25 to 60% by weight based on the total solid content of the overcoat layer, and the amount of the crosslinking agent is not particularly limited. About 0.1 to 0.5 parts by weight per part is preferred. The overcoat layer contains amorphous silica as a pigment,
Other pigments can be used in combination as long as the desired effects of the present invention are not impaired. As such other pigments,
Examples thereof include calcium carbonate, aluminum hydroxide, kaolin, calcined kaolin, magnesium carbonate, talc, and urea-formalin resin filler having an average particle diameter of about 0.1 to 7 μm including secondary particles.

[0015] The carboxy-modified polyvinyl alcohol is
For example, it can be obtained by saponifying a copolymer of vinyl acetate and an unsaturated carboxylic acid copolymerizable with vinyl acetate. Examples of such unsaturated carboxylic acids include acrylic acid, methacrylic acid, itaconic acid, maleic acid, muconic acid, fumaric acid and the like. The carboxy-modified amount in the carboxy-modified polyvinyl alcohol is not particularly limited.
-20 mol%, preferably about 0.5-10 mol%. Further, the degree of polymerization of the carboxy-modified polyvinyl alcohol is about 200 to 3000. The average particle diameter of the secondary particles of the amorphous silica contained in the overcoat layer is not particularly limited, but is preferably about 3 to 7 μm. If the average particle size of the secondary particles of the amorphous silica is less than 3 μm, the printability to the oil-based ink may be reduced with a decrease in the amount of voids in the overcoat layer.
If it exceeds, the recording image quality may be degraded. Such an average particle size is as follows: 15 g of amorphous Rishica and 85 g of water are 200 m

(M type) under a condition of 3000 rpm for 10 minutes, and then measured by Shimadzu SALD-2000 (by a laser diffraction method).

The uppermost UV curable resin layer adjacent to the overcoat layer is coated with 0.1 to 6.0 g of the uppermost coating solution containing an ultraviolet curable compound as a main component on the overcoat layer.
By applying ultraviolet rays after application so as to be about / m 2, the ultraviolet curable compound is polymerized and cured to be formed. By providing such an uppermost layer, it is possible to obtain excellent effects in prevention of rubbing and smearing on the recording of heat-sensitive recording, preservability of the recording portion, and recording running property. In particular, JISP8 in the top layer
147 has a coefficient of static friction (horizontal method) of 0.30
By setting the value to 0.60, the transportability during recording,
In addition, an effect of excellent transportability in the OCR reader after recording can be obtained. The uppermost layer having such a static friction coefficient value can be obtained by appropriately selecting the type, application amount, ultraviolet irradiation amount, polymerization initiator amount, additive and the like of the ultraviolet curable compound. The uppermost layer surface is provided on the surface of the overcoat layer except for the seal portion, and by providing a part of the overcoat layer surface, particularly about 30 to 99.5% of the overcoat layer surface, the uppermost layer after recording is not provided. An effect that is excellent in writing properties with a ballpoint pen on a portion, that is, on the overcoat layer, and in printing with an oil-based stamp ink can also be obtained. If the surface of the uppermost layer is less than 30 of the surface of the overcoat layer, the effect of improving the transportability may be reduced.
