Abstract

PROBLEM TO BE SOLVED: To provide a card with a magnetic stripe wherein productivity and economic performance are excellent and surface protection and a printing characteristic are improved by providing a surface printing layer beforehand on the back side of a transparent film stuck to the surface side of a card board. SOLUTION: A magnetic stripe 6 is stuck by an adhesive 7 to the surface of a thin square card board 1 made of a synthetic resin plate and a back surface printing layer 3 is formed on its back surface. A transparent film 5 is stuck thereto by an adhesive 10 for protecting the back surface printing layer 3. On the other hand, on the surface of the card board 1 stuck with the magnetic stripe 6, a surface printing layer 2 is formed on the rear of a transparent film 4 beforehand, then the transparent film 4 is stuck via an adhesive 9 and the magnetic stripe 6 is covered and protected. Thus, the difficulty of printing and unprinted portions caused by the level difference of the magnetic stripe 6 are eliminated and surface printing is performed easily, uniformly and accurately.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card with a magnetic stripe typified by a credit card and the like, and particularly, it aims to improve surface printing characteristics.

[0002]

2. Description of the Related Art Conventionally used credit card with a magnetic stripe (JIS II type) has a structure as shown in FIGS. 4 is an external perspective view of the entire credit card, and FIG. 5 is an enlarged cross-sectional view taken along the line AA in FIG. 1 is a card substrate made of a vinyl chloride plate, 2 and 3 are front and back printing layers applied to both front and back surfaces of the card substrate 1, and 4 and 5 are front and back printing layers 2.3.
Transparent film pasted on each to protect the
A magnetic stripe 6 has a magnetic tape, on which various information is input, attached on the transparent film 4 on the front side. The card substrate 1 having the front and back surface printing layers 2 and 3, the transparent films 4 and 5, and the magnetic stripe 6 have a laminated structure in which they are polymerized and integrated and then punched into a predetermined size. FIG. 6 shows a process of polymerizing and integrating the credit card with the magnetic stripe. Before the polymerization and integration, thermocompression-bonding adhesives 7, 9, and 10 are applied to the magnetic stripe 6 and the transparent films 4 and 5 in advance,
A method of sandwiching the card substrate 1 on which the front and back printing layers 2 and 3 are formed and heating and pressing is adopted. In FIG. 6, 12 indicates the direction of applying heat and 13 indicates the direction of applying pressure.

[0003]

However, in the above-mentioned conventional card with a magnetic stripe, the magnetic stripe 6 is used.
Since the magnetic stripe 6 is exposed on the surface, there is a problem that the presence of the magnetic stripe 6 limits the degree of freedom in printing characters, designs, etc. during surface printing, and that the protection of the magnetic stripe 6 is lacking. Therefore, recently, a concealment type credit card has been developed in which the surface of the card substrate 1 including the surface of the magnetic stripe 6 is printed to form the surface printing layer 2. FIG. 7 shows a sectional view of this concealed credit card, but this has a problem that it is difficult to perform uniform printing. That is, a thickness of 30 μ is formed on the card substrate 1.
When the magnetic stripe 6 of about m is attached, the step 11 is inevitably generated. On the other hand, when printing is performed on the surfaces of the card substrate 1 and the magnetic stripe 6, the thickness is several tens of μm even if a general screen printing method is adopted.
For this reason, it is difficult to perform uniform printing due to the existence of the step 11, and a print defect is likely to occur at the step 11 portion. There is a processing method of making the surface uniform by pressing or the like in order to improve such a problem, but this is economically disadvantageous because the number of processing steps increases, the productivity decreases, and the processing cost increases.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a card with a magnetic stripe capable of improving printing characteristics by further developing and concealing a card with a magnetic stripe of concealment type.

[0005]

A card with a magnetic stripe according to the present invention has a surface printed layer 2 on the back surface of a transparent film 4 on the front side, and the transparent film 4 is attached to a card substrate on which a magnetic stripe 6 is attached. It is characterized in that it is attached to the surface of No. 1 so as to also cover the surface of the magnetic stripe 6.

[0006]

Since the front surface printing layer 2 is provided on the back surface of the transparent film 4, there is no difficulty in printing or lack of printing due to the step 11 of the magnetic stripe 6 such as the above-mentioned conventional concealing type card with magnetic stripe, and it is easy and uniform. In addition, it is possible to perform surface printing with good accuracy.

[0007]

1 to 3 show one embodiment of a card with a magnetic stripe according to the present invention. FIG. 1 is a cross-sectional view of a card with a magnetic stripe, FIG. 2 is an external perspective view of a card with a magnetic stripe, and FIG. In FIG. 1 and FIG. 2, a magnetic stripe 6 is attached to the surface of a thin rectangular card substrate 1 made of a synthetic resin plate such as a vinyl chloride plate via an adhesive 7, while a back side printing layer 3 is formed on the back side. Is applied. In order to protect the backside printing layer 3, a transparent film 5 is attached on top of this via an adhesive 10.

On the surface of the card substrate 1 to which the magnetic stripe 6 is attached, the transparent film 4 is provided with the magnetic stripe 6
The surface printing layer 2 is applied to the back surface of the transparent film 4 in advance before the attachment, though it is also attached via an adhesive 9 to cover and protect it. The surface printing operation on the back surface of the transparent film 4 is performed by the step 11 of the magnetic stripe 6 such as the above-mentioned conventional concealing type card with a magnetic stripe.
There is no difficulty in printing due to, and printing can be performed easily, and uniform and accurate printing can be performed. As shown in FIG. 3, the card substrate 1, the magnetic stripe 6, and the transparent films 4 and 5 on the front and back are superposed in the above-mentioned arrangement state, and then heated and pressed from both front and back to be integrated with each other. . FIG.
Inside, 12 shows a heating direction and 13 shows a pressurizing direction.

[0009]

According to the present invention, since the front surface printing layer 2 is provided on the back surface of the transparent film 4 attached to the front surface side of the card substrate 1 having the magnetic stripe 6, this printing is easy and uniform. Therefore, it is possible to obtain a card with a magnetic stripe which can improve the printing characteristics and is excellent in productivity and economy.
