Description

Detailed Description of the Invention <Industrial Application Field> The present invention relates to the structure of a magnetic ticket sheet having a magnetic recording layer and a method for manufacturing the same, and more specifically, to issuing magnetic ticket sheets of two sizes by a common means. The present invention relates to the structure and manufacturing method of a magnetic ticket sheet.

<Prior art> Conventional magnetic ticket sheets are made by coating one side of a paper or resin sheet with a magnetic paint containing magnetic powder and a binder to form a magnetic recording layer, and magnetically oriented as shown in Figure 4A. It is shaped like an X and slit to a width of 30mm to form a roll.The roll is placed in a ticket issuing machine and cut to a length of 57.5mm when necessary.
The sheet is made into a sheet that can be used to issue 57.5mm magnetic tickets (B-tickets), the necessary magnetic information is written on it, the sheet is inserted into a 30mm wide gate, the magnetic information is read, and the gate is opened for practical use.

On the other hand, with the diversification of train tickets and associated gates, in order to obtain a magnetic ticket sheet with a width of 57.5 mm and a length of 86 mm, a slit with a magnetic orientation of X and a width of 57.5 mm is required as shown in Figure 4 B. Process it, set it in the ticket issuing machine, and cut it to a length of 86 mm when necessary to make a magnetic ticket (B
It is used as a ticket).

With this conventional method, when applying magnetic ticket sheets to gates with a width of 30 mm and a gate with a width of 57.5 mm, it is necessary to prepare two types of rolls for magnetic ticket sheets as shown in Figure 4 A and B. Therefore, this causes management problems around the ticket issuing machine. Therefore, the fourth
As shown in Figure C, it is required to cut and collect two types of magnetic ticket sheets, namely A ticket (57.5 x 86 mm) and B ticket (30 x 57.5 mm), from one roll width of 57.5 mm.

However, in the conventional magnetic ticket sheet roll shown in Fig. 4 (c), the A ticket is oriented in the X direction, so it can be inserted into a 57.5 mm wide gate as is, but the B ticket can be inserted into a 30 mm wide gate. When inserted into the magnetic field, the magnetic orientation direction and the recording direction are perpendicular to each other, resulting in a decrease in current conversion efficiency, which poses a practical problem.
In the figure, 11 is a magnetic sheet and 13 is a roll.

<Problems to be Solved by the Invention> The present invention is to cut and use magnetic ticket sheets of two sizes, A ticket and B ticket, from one magnetic ticket sheet roll as shown in FIG. 4C. Improve the difficulty of obtaining magnetic ticket sheets and make this possible.
In addition, the present invention provides a magnetic ticket sheet that exhibits sufficient magnetic recording characteristics in recording, reproducing, overwriting, etc. at high recording density and high speed conveyance, and also provides a method for manufacturing the same.

<Means for Solving the Problem> As a result of intensive studies to solve this problem, the present invention has found that although the conventional magnetic ticket sheet and its cross-sectional layer structure are not changed in the slightest, the magnetic orientation direction of the magnetic recording layer is changed. By configuring the sheet at a certain angle to the longitudinal direction of the sheet, two types of magnetic ticket sheets with a common size on one side but different sizes on the other side can be created from the same ticket roll as needed. We have discovered such a sheet structure and its manufacturing method. The outline is as follows.

An example of the layer structure of the magnetic ticket sheet according to the present invention is as follows:
As shown in FIG. 1A, a paper support 1, resin layers 2a and 2b such as polyolefin on both sides thereof, a thermosensitive recording layer 3 provided on the resin layer 2a, and a magnetic recording layer 4 provided on the resin layer 2b. , letters and 1
Alternatively, it consists of a pattern printed layer 5 and a protective layer 6.

Another example of the layer structure of the magnetic ticket sheet according to the present invention is as shown in FIG. A directly provided magnetic recording layer 4, a printed layer 5 of characters and 1 or a picture,
It consists of a protective layer 6.

This constituent material will be described later. However, in the present invention, the structure of this magnetic recording layer is completely different from the conventional one.

That is, as shown in Fig. 2, two sizes of magnetic ticket sheets are provided by magnetically orienting the magnetic ticket sheet in the direction of 40° to 50° or 130° to 140° with respect to the longitudinal direction of the magnetic ticket sheet. (Claims 1 and 2), and in its production, a step of applying a magnetic paint containing ferromagnetic powder and a binder to the surface of the support;
While moving the support in the longitudinal direction, magnetically align the coated layer of the magnetic paint in a direction of 40° to 50° or 130° to 140° with respect to the longitudinal direction of the support. and a step of providing a resin layer on one or both sides of a paper support pair, and a magnetic paint containing ferromagnetic powder and a binder on the surface of the resin layer. and, while the support is advanced in the longitudinal direction, the magnetic coating layer is undried at an angle of 40° to 50° or 130° to 140° with respect to the longitudinal direction of the support. A method for manufacturing a magnetic ticket sheet (Claim 7) comprising the step of magnetically orienting the sheet in the direction of.

Further, the resin layer of the magnetic sheet is a polyolefin resin layer (Claim 3), the printing layer 5 and the protective layer 6 are provided on the magnetic recording layer 4 (Claim 4),
The provision of the recording layer 3 on the opposite surface to the magnetic recording layer 4 (claim 5) has already been described.

Next, the materials constituting the magnetic ticket sheet of the present invention will be explained in detail.

The supports constituting the present invention include resinous supports made of plastic films such as polyethylene terephthalate, polyimide, and vinyl chloride resins, paper,
A paper support such as synthetic paper is applied. In the case of paper, a resin layer (barrier layer) is provided on the surface of the paper to create magnetic recording based on impregnation of the paper support with magnetic paint, which tends to occur when a magnetic recording layer is provided directly on the paper. Non-uniformity of the layer can be prevented. If the support is made of resin, impregnation with the magnetic paint will not occur, so a magnetic recording layer can be provided directly on it, but it is important to select a material that is not easily attacked by the solvent of the magnetic paint that will be applied later. preferable.

The resins used for the resin layer constituting the present invention include polyvinyl alcohol, modified polyvinyl alcohol, hydroxyethyl cellulose, methyl cellulose, starches, styrene/maleic anhydride copolymer, vinyl acetate/maleic anhydride copolymer, styrene/butadiene. Copolymer, vinyl chloride resin or its copolymer, acrylic acid resin or its copolymer, polyester resin, polyethylene, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer , ethylene-propylene copolymer, polyolefin resin such as polypropylene, etc., and polyolefin resin is particularly preferred.

In addition, white pigments, white pigments, etc. are added to these resins as necessary.
For example, inorganic fillers such as calcium carbonate, titanium oxide, talc, kaolin, calcined kaolin, diatomaceous earth, calcium carbonate, magnesium carbonate, and aluminum hydroxide, or organic fillers such as polyethylene resin powder can be added.

In this case, the amount of filler added is preferably 5 to 20% by weight. When polyolefin resin is used here, the thickness of the layer is preferably about 5 to 20 μm, and about 10 to 20 μm.
More preferably, the thickness is 15 μm. It is also possible to use the polyolefin resin layer by subjecting it to a surface treatment such as corona discharge to further improve the adhesive strength with the heat-sensitive recording layer and the magnetic recording layer. Note that even when other resins are used, those having a thickness similar to the above are easy to handle.

The magnetic recording layer in the magnetic ticket sheet of the present invention is

Or formed by printing. Magnetic powders include γ-Fe ₂ O ₃ , barium ferrite,
Ferromagnetic materials such as strontium ferrite are used, but in order to prevent the problem of magnetically recorded information being erased or attenuated by ordinary permanent magnets, barium ferrite or strontium ferrite must have a coercive force of 1500 to 5000 oersteds. It is preferable to apply high coercive force materials. In order to improve smoothness and abrasion resistance, a surface layer made of nitrocellulose, polyurethane resin, etc. can be further coated or printed on the magnetic recording layer.

Further, if necessary, other additives, such as fatty acid amide and white pigment, may be added to the heat-sensitive recording layer formed from the above-mentioned leuco dye, acidic substance, and binder. Note that heat-sensitive materials other than leuco dye color-forming materials, such as diazo color-forming materials, can also be applied to the heat-sensitive recording layer in the present invention.

Furthermore, if necessary, for example, fatty acid metal salts, wax, white pigments, and waterproofing agents are added to the protective layer. In the present invention, the protective layer can also be provided on the heat-sensitive recording layer. In that case,
A water-soluble resin is preferable in order to prevent unnecessary color development of the leuco dye.

Next, the printing layer referred to in the present invention is a layer that is used to print, for example, a cautionary note or a picture pattern to give a beautiful appearance, which is necessary for a magnetic ticket sheet, and printing on a black magnetic recording layer is performed using white or silver ink. Alternatively, a white concealing layer may be provided on the magnetic recording layer before printing, and black ink may be printed on top of the white concealing layer. Note that the printing layer can also be provided on the heat-sensitive recording layer.

<Function> The general functions of the magnetic ticket sheet of the present invention based on its layer structure are as follows and are similar to those of the prior art. In other words, when the support is made of paper, firstly, by providing a resin layer such as polyolefin resin on one or both sides of the support, the thermal shrinkage rate and expansion and contraction rate due to moisture absorption and dehumidification of the thermosensitive recording layer and the magnetic recording layer can be controlled. The difference is alleviated and the magnetic ticket sheet does not curl at all, and dimensional changes due to changes in humidity are also reduced, improving dimensional stability. As a result, the running performance of the magnetic ticket sheet inside the recording device and the recording/reproducing device is no different from the applicant's prior art.

In addition, by providing a resin layer such as a polyolefin layer, the heat-sensitive recording layer becomes an extremely uniform and dense layer, so the coating amount is approximately 70% of that when the heat-sensitive recording layer is provided directly on the paper support. Sufficient image density can be obtained. Furthermore, the clarity and uniformity of images were also significantly improved.

In addition, by providing a resin layer such as a polyolefin layer, it is possible to prevent the magnetic recording layer from penetrating into the paper support, so the whiteness of the heat-sensitive recording layer on the surface is increased, and even if the image density is the same, Contrast is significantly better and appearance is also improved.

In addition, with ordinary paper-based magnetic ticket sheets, part of the magnetic paint penetrates into the base at the same time as the magnetic paint is applied, so even if magnetic field orientation treatment is applied, the magnetic powder in the magnetic paint is not sufficiently oriented. .

In the magnetic ticket sheet according to the present invention, by providing a resin layer such as a polyolefin layer, penetration of the magnetic paint into the base can be suppressed, so that magnetic field orientation can be sufficiently achieved. That is, a resin layer such as a polyolefin layer is essential to the magnetic ticket sheet according to the present invention.

In addition, by providing a resin layer such as a polyolefin layer, the surface smoothness of the heat-sensitive recording layer and the magnetic recording layer is increased, and when printing characters and/or patterns on the heat-sensitive recording layer and the magnetic recording layer. The print quality is significantly improved.

It has already been mentioned that the magnetic sheet according to the present invention is characterized by the magnetization direction of the magnetic layer, and the case where magnetic ticket sheets of two sizes are issued from one magnetic sheet roll will be explained with reference to FIG. 3. In the figure, a magnetic ticket sheet A having a width of 57.5 mm and a length of 86 mm is cut and issued from a roll 13 of a magnetic sheet 11 according to the present invention having a width of 57.5 mm, and the magnetization curve of the ticket is It is possible to obtain a magnetic ticket sheet that has a certain angle determined in the range of 40° to 50° or 130° to 140° with respect to the longitudinal direction of the magnetic ticket sheet, and can be easily inspected at a gate.

Next, when issuing a magnetic ticket sheet B ticket with a width of 30 mm and a length of 56 mm, this magnetic ticket sheet is issued by making the width of the magnetic sheet roll the length of the magnetic ticket sheet and cutting it into a length of 30 mm. This magnetic orientation has a sufficient magnetic sorting function in the longitudinal direction of the magnetic ticket sheet B as well as the magnetic ticket sheet A, and also has a ticket inspection function at the ticket gate. That is, sufficient electromagnetic conversion efficiency can be obtained even if the magnetic ticket sheet B is inserted through a gate having a width of 30 mm. Therefore, if one ticket issuing machine is prepared, tickets of two different sizes can be issued as needed using one magnetic sheet roll according to the present invention, which greatly improves ticket issuing efficiency and saves equipment space. This greatly contributes to cost reduction as well as a reduction in

The manufacturing process differs from conventional methods in that the magnetic orientation, which is performed in an undried state after the magnetic paint is applied, is performed from the longitudinal direction of the sheet as shown in Figure 2.
The purpose is to set the angle to be within the range of 40° to 50° or 130° to 140°.

In that case, in order for the completed magnetic ticket sheet to be oriented in the 45° (135°) direction, when applying the magnetic paint, the magnetic orientator must be rotated 45° (135°) to the coating direction. 135°) It's not just a matter of tilting it. The installation angle of the magnetic orientator must be adjusted between 40° and 50° depending on conditions such as coating speed and paint viscosity.

In addition, the electromagnetic conversion characteristics are good in both directions,
Even with overwriting under the same conditions, stable recording and playback was possible.

In addition, in order to evaluate the thermal recording characteristics, static coloring characteristics were measured using a thermal gradient recording tester (manufactured by Toyo Seiki Co., Ltd.).
Further, dynamic color development characteristics were recorded using a lined type thin film head at an energy of 0.45 W (1 mJ/dot).

As a result, the color density and image resolution were good, and the whiteness of the surface of the heat-sensitive recording layer was also very good.

Apply the following magnetic recording layer paint to one side of this coated surface for 20m/m2 so that the solid content is 31g/ ^m2 .

Recording and reproduction were performed at a recording density of 210FCI in the coating direction and the perpendicular direction of the magnetic ticket sheet, and the outputs in both directions were compared and showed almost the same values. However, the electromagnetic conversion characteristics were poor in both directions, and when overwriting was performed under the same conditions, stable recording and reproduction were not possible and errors occurred.

<Effects of the Invention> The magnetic ticket sheet of the present invention has the same cross-sectional structure as the conventional one, except that the direction of magnetic orientation is determined between 45° and 50° or between 130° and 140° at the stage of forming the magnetic recording layer. By simply setting the angle at The accompanying management costs can be significantly reduced.

In addition, since a polyolefin resin layer is provided between the magnetic recording layer and the support, the output is almost the same in both the direction in which the magnetic paint is applied and in the direction perpendicular to the direction of application, resulting in good magnetic properties. It has become possible to achieve a high squareness ratio in the 45° (135°) direction with respect to the coating direction, which is necessary to maintain recording characteristics.
