Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a card with a magnetic stripe.

[Prior Art] Recently, it has been considered to provide a magnetic stripe on an electronic card such as a card-type small electronic calculator generally called a card calculator so that the electronic card can also be used as a magnetic stripe-type credit card or the like. Has been.

When a magnetic stripe is provided on an electronic card like this,
Generally, a method is used in which a magnetic stripe is printed on the outer surface of an exterior sheet (resin sheet) provided on the back surface of the card body that houses the input / output module, and the exterior sheet is laminated on the back surface of the card body.

[Problems to be solved by the invention]

However, conventionally, an adhesive is applied over the entire inner surface of the exterior sheet or the back surface of the card body to laminate the exterior sheet and the card body.
There is a problem that minute irregularities are generated on the magnetic stripe on the surface of the exterior sheet. This is because the application of the adhesive is generally performed by spreading the adhesive dropped on a part of the application surface with a squeegee or the like on the entire application surface. This is because it is difficult to make uniform, and therefore, unevenness can be formed on the laminated exterior sheet due to subtle unevenness of the applied adhesive layer, and also bubbles are generated in the applied adhesive layer, Even when minute dust in the air adheres to the surface of the adhesive layer, the laminated exterior sheet has irregularities. And, conventionally, as described above, since the adhesive is applied to the entire surface of the exterior sheet or the card body to laminate the exterior sheet and the card body, the unevenness generated on the laminated exterior sheet causes a magnetic field of the exterior sheet. This means that stripes can also be formed.Therefore, when the magnetic information recorded in the magnetic stripe is read by the magnetic head, the contact pressure of the magnetic head with respect to the magnetic stripe surface fluctuates, and the read output is locally reduced, or the jitter is reduced. (Disturbance of pulse width, pulse width, pulse position, pulse interval, etc.) occurs, and it is impossible to accurately write the recording information on the magnetic stripe.

The present invention has been made in view of the above situation, and its purpose is to provide an outer sheet laminated on a card body with a non-uniform adhesive coating thickness and bubbles in the adhesive layer. Even if irregularities due to the influence of adhered dust occur, the recording area of the magnetic stripe provided on the outer surface of the exterior sheet is not irregular, so that magnetic information can be read and written accurately. Is to provide a card.

[Means for solving problems]

In this invention, an adhesive for laminating both of the card body and an exterior sheet having a magnetic stripe on the outer surface is applied except at least a portion corresponding to the magnetic stripe or the recording area, and The card body and the exterior sheet are adhered only in the area that does not correspond to the recording area of the magnetic stripe.

[Action]

That is, according to this invention, the adhesive for laminating the card body and the exterior sheet is not interposed in the portion corresponding to the recording area of the magnetic stripe provided on the outer surface of the exterior sheet, so that the coating thickness of the adhesive is not uneven. The unevenness of the outer sheet due to the influence of bubbles and dust in the adhesive layer is prevented from occurring in the recording area of the magnetic stripe.
