Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is an improvement that can prevent the dirt of the card when it is handled by hand from adhering to the belt or roller for transporting the reader / writer used during writing and reading to the recording unit. Is related to the card.
[0002]
[Prior art]
There are various sizes of recording media provided with a recording portion on a base material, but a so-called card size (hereinafter referred to as a card) is frequently used because it is convenient to carry. Various recording units are used. Of these, the magnetic recording layer is often used because it is easy to write, read and erase information. In a magnetic card or the like, writing, reading, or erasing of information for a magnetic recording layer is performed by a magnetic head while being conveyed at a constant speed using a belt or roller of a reader / writer.
[0003]
Taking the most common magnetic card as an example, the magnetic card is transported using the friction between the belt or roller for transport and the card, so if the card surface is slippery, the card is transported. Unevenness of speed occurs. In particular, in the belt method in which the card is conveyed between two belts, the friction between the belt and the card is important, and if the card is slippery, the magnetic output fluctuates greatly, resulting in writing and reading errors. Sometimes. In an extreme case, the card slips and stops temporarily, and there is a case where no magnetic output is temporarily generated. Therefore, it is necessary that the friction coefficient of the card surface is relatively high.
[0004]
However, when processing magnetic cards using a ticket vending machine or an encoder, a large number of magnetic cards are stacked, and one by one is taken out and automatically supplied. In this respect, it is preferable that the coefficient of friction of the card surface is low because the slippage is poor and the magnetic card cannot be supplied smoothly in the feed section of a ticket machine or encoder. This is inconsistent with the relatively high coefficient of friction required for
[0005]
Apart from these points of friction, when writing or reading on a magnetic card, dirt on the belt or roller of the reader / writer becomes a problem. This is because when using the above ticket vending machines and encoders, new magnetic cards are often used. However, the magnetic cards transported in the reader / writer have been handled by people who handle them. This is because the surface of the roller and the belt gradually becomes slippery because they are deposited and contaminated, and they are deposited on the belt or roller of the reader / writer, particularly the joint of the belt.
[0006]
In order to eliminate the contamination of the belt or the roller, it has been proposed to perform cleaning by dampening and transporting a cleaning card in which a nonwoven fabric is bonded to a paper or a film with alcohol in a reader (for example, (See Patent Document 1).
[0007]
[Patent Document 1]
JP-A-8-45038 (pages 2 and 3)
[0008]
Although cleaning using the above cleaning card is effective, a cleaning card and a dedicated card reader capable of handling alcohol are required. If you don't have a dedicated card reader, you must supply a cleaning card that has been manually moistened with alcohol. Therefore, it is preferable to use a magnetic card that does not transfer contaminants to the belt or roller of the reader / writer even if it is contaminated so that it does not require much cleaning.
[0009]
[Problems to be solved by the invention]
In the present invention, the coefficient of friction of a card having a recording unit such as a magnetic card, which is written and read using a reader / writer, is suitable for conveyance in the reader / writer, and a ticket vending machine or encoder is used. When processing by using, it is an object to make it possible to secure a slip between the cards so as not to hinder the feed unit in which a large number of cards are stacked and taken out one by one. The present invention also provides a card with less transfer of contaminants to the belt and roller of the reader / writer so that the card has favorable friction characteristics and can reduce the frequency of cleaning. This is also an issue.
[0010]
[Means for Solving the Problems]
According to the inventor's study, the inconsistent coefficient of friction between the leader writer and the ticket machine or encoder is obtained by increasing the coefficient of friction by roughening the portion of the reader / writer where the belt or roller for conveyance contacts, and Preferably, by setting the portion with a higher coefficient of friction as a recess, when the cards are stacked, the portion with the higher coefficient of friction does not affect the sliding between the cards, resulting in contradictory friction. It is possible to make the coefficients compatible. Moreover, the part which raised the friction coefficient was able to reach this invention. Further, the roughened portion can suppress the transfer of dust or dust to the belt or roller even if dust or dust adheres. The concrete present invention based on these is as follows.

[0017]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 2, the card 1 of the present invention is preferably of a size that fits in the palm of the hand, and is more preferably a so-called credit card size, usually about 54 mm × about 86 mm. . The thickness of the card 1 is preferably such that the thickness of the card 1 does not become excessive when stacked, for example, from about 100 μm to about 1 mm, while ensuring the rigidity of the card 1.
[0018]
The card 1 is often transported in a direction parallel to the longitudinal direction in the reader / writer. In this case, the card 1 is used for transporting a card that the reader / writer has in parallel with the transport direction, that is, in the longitudinal direction of the surface of the card 1. A belt-like area where the belt or roller contacts, that is, a contact zone 2 is assumed. The contact zone 2 is not one as shown in the figure, but may be a plurality of two or three, but in the drawings including the following, the contact zone 2 is drawn as one.
[0019]
In order for the card 1 to be conveyed in the reader / writer without slipping between the belt and the roller, it is preferable that at least the surface of the contact zone 2 is a rough surface 6. FIGS. 3A to 3E all show a cross-sectional view taken along the line AA of the card 1 shown in FIG. 2, that is, a cross section cut along a plane parallel to the short side of the card 1. As shown in FIG. 3A, the card 1 has, for example, a recording unit 4 (as a preferred example, a magnetic recording layer) on the lower surface of the base material 3 (upper and lower follow the upper and lower sides in the figure, and so on). The surface in the contact zone 2 on the upper surface of the laminated body 5 formed by laminating is a rough surface 6.
[0020]
As described above, the card 1 only needs to have the rough surface 6 at least in the contact zone 2, and therefore, a plurality of strip-shaped areas in the contact zone 2 may be the rough surface 6 (FIG. 4). In various aspects described below, the area of the rough surface 6 in the contact zone 2 may be plural in this way. Further, the rough surface 6 of the card 1 may not be limited to the range of the contact zone 2 but may be continuous from the range of the contact zone 2 to the adjacent area. Another part which is separated may be a rough surface 6, and as shown in FIG. 3B, the contact zone 2 on the upper surface of the laminate 5 formed by laminating the recording unit 4 on the lower surface of the substrate 3. The entire surface including the rough surface 6 may be used.
[0021]
As described above, the card 1 having at least the contact zone 2 having the rough surface 6 can ensure friction between the belt and the roller because the rough surface 6 contacts the belt and the roller in the reader / writer. Carried without slipping.
[0022]
By the way, if the cards 1 described with reference to FIGS. 3A and 3B are overlapped with each other, the back surface of the next card 1 comes into contact with the contact band 2 so that the friction between the cards 1 is increased. There is a tendency to become large, and trouble is caused in a ticket vending machine or an encoder in which the cards 1 are stacked and slid in the surface direction and supplied one by one.
[0023]
FIG. 3C illustrates a card 1 that can eliminate the trouble that occurs when such a contact zone 2 has the same plane as other portions. The contact zone on the upper surface of the laminate 5 is illustrated in FIG. 2 is the rough surface 6, and the contact zone 2, which is the rough surface 6, is a recess 7 with respect to a portion other than the rough surface. When the cards 1 described with reference to FIG. 3C are overlapped, the rough surface 6 of the contact band 2 and the back surface of the next card do not contact each other. There is no problem in separating and feeding one by one by sliding in the surface direction.
[0024]
In the example described with reference to FIG. 3C, it is assumed that the width of the recess 7 is the same as the width of the contact zone 2, but the width of the recess 7 is wider than the width of the contact zone 2. Also good. As shown in FIG. 3D, the rough surface 6 may be formed with a width wider than the contact zone 2 on the upper surface of the laminate 5, and the concave portion 7 having the same width as the rough surface 6 may be formed. In the case where the width of the recess 7 is wider than the width of the contact zone 2 in this way, only the contact zone 2 of the recess 7 may be a rough surface and the other portion may be a smooth surface.
[0025]
By the way, although the rough surface 6 demonstrated like what the surface itself of the base material 3 has in the example which quoted FIG. 3 (a)-FIG.3 (d), the rough surface 6 is different from the base material 3. It can also be formed by stacking these layers.
[0026]
For example, as shown in FIG. 3 (e), the recording unit 4 is laminated on the lower surface of the substrate 3, and the roughened layer 61 is laminated on the upper surface of the substrate 3 to form the roughened surface 6. An example is the card 1 in which the roughened surface 8 in the contact zone 2 is exposed as a recess 7 by laminating the smoothing layer 8 except on the contact zone 2. Similarly to the card 1 described with reference to FIG. 3 (c), the card 1 described with reference to FIG. 3 (e) is slid in the surface direction in the ticket vending machine or the encoder. There is an effect that does not cause any trouble when supplying separately. In addition, the thing of any structure of the card | curd 1 demonstrated with reference to FIG.3 (a)-FIG.3 (d) roughens the rough surface 6 which the surface of the base material 3 has on the surface of the base material 3 It can be set as the structure replaced with the rough surface by having laminated | stacked the layer.
[0027]
Next, a more preferred embodiment of the card 1 of the present invention will be described with reference to FIG. In the card 1 shown in FIG. 1, a recording portion 4 (for example, a magnetic recording layer) is laminated on the lower surface of a base material 3, and a roughening layer 61 is laminated on the upper surface of the base material 3 to form a rough surface 6. The pattern layer 9 a and the smoothing layer 8 are sequentially laminated on the rough surface 6 except for the contact zone 2, and the rough surface 6 in the contact zone 2 is exposed as a recess 7. In addition, a pattern layer 9 b is laminated on the lower surface of the recording unit 4 via a concealing layer 10. The card 1 of this preferred embodiment is preferably used as a prepaid card for play. The base material 3 is, for example, a polyethylene terephthalate resin film, and the thickness of the base material 3 is, for example, 188 μm.
[0028]
This card 1 is different from the card 1 described with reference to FIG. 3 (e) in that the smoothing layer 8 is laminated with a pattern layer 9a on the upper surface of the base material 3. Since the rough surface 6 in the contact zone 2 is the same as the recess 7, the card 1 is also slid in the surface direction and supplied one by one in the ticket machine or encoder. It will not cause any trouble. In addition, the design of the external appearance of the surface of the card | curd 1 can be improved or a required display can be performed by selecting suitably the pattern, character, etc. which comprise the pattern layer 9b added here.
[0029]
Further, a concealing layer 10 and a pattern layer 9b are added to the lower surface of the recording unit 4, but the concealing layer 10 is laminated to conceal the color and shape of the recording unit 4 so that they cannot be seen. In addition to the appearance of the back surface of 1 being uniform, the card 1 can be appropriately colored, and the concealing layer 10 contains extender pigments or fine particles of abrasive grains. When the recording / erasing head (for example, a magnetic head) in the encoder is transported, it can be used as a cleaning layer for cleaning the head. Further, by appropriately selecting the pattern and characters constituting the pattern layer 9b, the design of the appearance of the back surface of the card 1 can be enhanced or necessary display can be performed as with the pattern layer 9a on the front surface of the card 1. In general, it is preferable to form characters such as notes.
[0030]
In the card 1 described with reference to FIG. 3 and FIG. 1, the base material 3 and the recording unit 4 are laminated, and the rough surface 6 is provided on the opposite side of the recording unit 4 of the base material 3. Or the card 1 having such a configuration, the recording unit 4 is a magnetic recording layer, and the side on which the recording unit 4 is laminated is a reader / writer. It can be conveyed so as to be on the magnetic head side, and the effect of having the rough surface 6 or the effect of having the rough surface 6 and the concave portion 7 on the side opposite to the recording unit 4 can be exhibited. On the contrary, if a rough surface is provided on the side where the recording unit 4 is laminated, or if a rough surface and a concave portion are provided, the effect of having the rough surface 6 on the side having the recording unit 4; Alternatively, the effect of having the rough surface 6 and the concave portion 7 is produced. In addition, both of them can have a rough surface 6 or a structure having a rough surface 6 and a recess 7 on either side of the laminate in which the base material 3 and the recording unit 4 are stacked. On the other side, the effect of having the rough surface 6 or the effect of having the rough surface 6 and the recess 7 can be exhibited.
[0031]
As a material of the base material 3 of the card 1 of the present invention, plastic, metal foil, paper, or the like can be used, but it has an appropriate rigidity, does not generate paper powder, etc., and is molded by heating. Plastics are preferable in that they are suitable for use. Examples of the plastic include polyester such as polyvinyl chloride, polyvinyl alcohol, polysulfone, and polyethylene terephthalate (abbreviation: PET), polyarylate, polycarbonate, polyamide, polyimide, cellulose diacetate, cellulose triacetate, polystyrene, acrylic, polypropylene, polyethylene, or Examples thereof include those made of plastics such as polyolefin vinyl alcohol. Further, when heat resistance is required, amorphous polyester, a blend resin of amorphous polyester and polycarbonate, or the like may be used. When the base material 3 is made of plastic as a material, it may be either transparent or opaque. However, when ensuring the concealing property, it is particularly preferable to use an opaque and concealing material such as white.
[0032]
The recording unit 4 of the card 1 of the present invention includes various recording units, such as a magnetic recording layer, an optical recording layer (including a hologram), a heat-sensitive recording layer, a heat-sensitive color-decoloring layer, and an image receiving image for sublimation recording. The magnetic recording layer may be one or more of a layer, a writable layer for signatures, an IC module, or an LSI module, but is preferably a magnetic recording layer because it is highly popular and easy to handle.
[0033]
Among the above, those from the magnetic recording layer to the writable layer are laminated on the substrate 3 by applying a coating composition for forming these layers and solidifying by drying or the like, or separately It is preferable to laminate the recording unit 4 on the substrate by pasting the substrate 4 on the substrate 3 or by transferring and removing the substrate. In the case of a hologram, interference exposure or shaping for imparting hologram information is performed as necessary. In the case of an IC module or an LSI module, the substrate 3 is laminated by, for example, embedding holes in advance. A magnetic recording layer preferable as the recording unit 4 is a thin film obtained by vapor deposition or sputtering of magnetic metal, or a resin layer in which magnetic metal powder is dispersed, and these may be accompanied by a film-like substrate.
[0034]
In order to make the upper surface of the base material 3 into the rough surface 6, molding is performed by pressing the base material 3 while heating it using a mold for molding having a reverse shape of the rough surface 6 with a predetermined uneven shape. There is a way to do it. In this case, if a mold having a convex portion on the mold surface is used as the forming mold, the rough surface 6 and the concave portion 7 can be formed simultaneously.
[0035]
In order to form the rough surface 6 by laminating the rough surface layer 61, the rough surface layer 61 may be composed of a resin layer containing inorganic fine particles such as silica, alumina, titanium dioxide, or calcium carbonate. Preferably, it can be formed by coating or the like. The diameter of the fine particles is preferably about 0.2 μm to 3 μm. If the diameter of the fine particles is the lower limit, the roughened layer 61 has a maximum average roughness (Ra) of about 0.3 μm on the surface. If the diameter of the fine particles is the upper limit value, the roughened layer 61 having a maximum average roughness (Ra) of about 4 μm on the surface is obtained, and the maximum average roughness (Ra) is obtained. If it is less than the lower limit value, sufficient friction between the belt and the roller will not occur, so that there is a problem in conveyance, and if the maximum average roughness (Ra) exceeds the upper limit value, the uniformity of the coating film is lost. In addition, also in the rough surface 6 by shaping, it is preferable that the average roughness (Ra) of the surface is in the above range.
[0036]
Regardless of whether it is shaping or the lamination of the roughened layer 61, the surface of the roughened surface 6 is transferred to the belt or roller for transport in the reader / writer even if dirt or dust adheres. Hateful. This is thought to be because the adhesion of dirt and dust to the rough surface 6 is stronger than the adhesion to the flat surface. In particular, the roughened layer 61 is laminated rather than the rough surface that the substrate 3 has directly on the upper surface. As a result, the rough surface has a greater adhesion of hand dust, and the transfer to the belt or roller for transport in the reader / writer is less likely to occur. This is presumably because the dirt is absorbed in the roughened layer 61 due to the presence of the inorganic fine particles in the roughened layer 61. The rough surface 6 can be formed either by shaping or by laminating the roughening layer 61. However, in the case of shaping, the obtained unevenness is more than the unevenness according to the mold. On the other hand, the roughened layer 61 has a tendency to become shallower, and the roughened layer 61 is roughened in that the unevenness to be obtained is determined by the diameter and mixing ratio of the fine particles to be mixed, and the desired unevenness can be surely obtained. The lamination of the surface layer 61 is preferable. As the fine particles, fine particles such as silica having a large specific surface area are more preferable in terms of absorption.
[0037]
The smoothing layer 8 is for covering a part on the roughening layer 61 and smoothing the surface of the covering portion. Since the smoothing layer 8 fills the rough surface of the lower roughening layer 61, the smoothing layer 8 is preferably formed by application of a coating composition that has a large amount of resin and is easy to flatten the surface after application. Application may be performed using a solution such as a thermosetting resin, but more preferably, a prepolymer, an oligomer, and / or a monomer having a polymerizable unsaturated bond or an epoxy group in the molecule is appropriately mixed. Application is performed using an ionizing radiation curable resin composition, and after application, ionizing radiation such as ultraviolet rays or electron beams, particularly ultraviolet rays are irradiated and cured to form a smoothing layer.
[0038]
Examples of prepolymers and oligomers in the ionizing radiation curable resin composition include unsaturated polyesters such as unsaturated dicarboxylic acid and polyhydric alcohol condensates, polyester methacrylate, polyether methacrylate, polyol methacrylate, melamine methacrylate, etc. Methacrylates, polyester acrylates, epoxy acrylates, urethane acrylates, polyether acrylates, polyol acrylates, acrylates such as melamine acrylates, and cationic polymerization type epoxy compounds are mentioned. And methacrylic acid esters. Furthermore, a photopolymerization initiator and a photopolymerization accelerator are added to the ionizing radiation curable resin composition as necessary.
[0039]
The thickness of the smoothing layer 8 is preferably about 1 μm to 6 μm. If the thickness is less than the lower limit, the smoothing effect is poor, but if the upper limit is exceeded, the smoothing effect is not improved. The surface of the smoothing layer 8 and the surface of the roughening layer 61 have a maximum level difference corresponding to the upper limit of the thickness of the smoothing layer 8, but the transport belt or roller is on the surface of the card 1. Since contact is made with pressure, there is no problem of insufficient contact.
[0040]
The hiding layer 10 is made of a composition in which a pigment having high hiding power is dispersed in a binder resin, and preferably made of a composition in which metal or metal particles exhibiting a metal color are dispersed as a main component. For the purpose of improving the concealability, a highly concealable pigment such as titanium dioxide may be included. Examples of metal or alloy particles include Cr, Fe, Co, Ni, Cu, Ag, Au, Ge, Al, Mg, Sb, Pb, Cd, Bi, Sn, Se, In, Ga, or Rb. Metals or alloys based on these metals can be used.
[0041]
Examples of the binder resin constituting the concealing layer 10 include cellulose derivatives such as ethyl cellulose, nitrocellulose, ethyl hydroxycellulose, cellulose acetate propionate, or cellulose acetate, styrene resins such as polystyrene and poly-α-methylstyrene, or styrene co-polymers. Polymer resin, polymethyl methacrylate, polyethyl methacrylate, polyethyl acrylate, acrylic resin such as polybutyl acrylate or methacrylic resin alone, or copolymer resin, rosin, rosin-modified maleic acid resin, rosin-modified phenol Resin, or rosin ester resin such as polymerized rosin, polyvinyl acetate resin, coumarone resin, vinyl toluene resin, polyvinyl chloride resin, polyester resin, polyurethane resin, or polyvinyl Butyral resin or the like can be used.
[0042]
Since the concealing layer 10 contains metal or alloy particles, it has a cleaning property with respect to the magnetic head. However, if necessary, a magnetic powder such as titanium dioxide, alumina, or microsilica is added to the magnetic head. The cleaning performance for cleaning the head is improved.
[0043]
The pattern layer 9a on the upper surface side and the pattern layer 9b on the lower surface side of the card 1 are usually formed by a printing method, and the design of the appearance of the surface of the card 1 is enhanced by appropriately selecting a pattern or characters. Or necessary display. As a picture or a character, there can be a character, a figure, a symbol, a character, a photograph, a picture, a barcode, or an OCR character. When the card 1 is a credit card or a deposit / saving card of a financial institution, a part of characters may be formed by embossing.
[0044]
