Abstract

Abstract An information card of the magnetic-type in which card information is magnetically recorded. The card comprises a base sheet made of a thermoplastic material having a desired rectangular shape and a thickness enough to give the card required mechanical strength, and a magnetic sheet consisting of a support layer of the same thermoplastic material as the material of the card base and a magnetizable layer formed on one surface of the support layer. The magnetizable layer may be covered with a protective coating. The magnetic sheet and the card base are put together with the other surface of the support layer being in contact with one surface of the card base. The card base and the magnetic sheet are then heated and compressed so that the contacting portions of the material of the card base and the support layer of the magnetic sheet are fused together to produce a card of unitary construction. The exposed surface of the card base may be provided with symbols printed thereon expressing necessary information, and this surface may be covered by a transparent coating for protection of the printed information.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 127 words
An information card comprising: a card base of a thermoplastic material having a thickness enough to give said card substantial mechanical strength; and a magnetic sheet consisting of a magnetizable layer in which card information is recorded and a support layer on one surface of which said magnetizable layer is formed, said support layer being made of the same thermoplastic material as said card base; said card base and said magnetic sheet being laminated, with the other surface of said support layer being in contact with one surface of said card base, and compressed while applying heat thereto, so that the material of said support layer and that of said card base are fused together to form said base and sheet into a card of unitary construction.
Claim 2
Dependent Claim 127 words
An information card comprising: a card base of a thermoplastic material having a thickness enough to give said card substantial mechanical strength; and a magnetic sheet consisting of a magnetizable layer in which card information is recorded and a support layer on one surface of which said magnetizable layer is formed, said support layer being made of the same thermoplastic material as said card base; said card base and said magnetic sheet being laminated, with the other surface of said support layer being in contact with one surface of said card base, and compressed while applying heat thereto, so that the material of said support layer and that of said card base are fused together to form said base and sheet into a card of unitary construction.
Claim 3
Dependent Claim 25 words
The information card of claim 1, further including a coating formed on the exposed surface of said magnetizable layer for protection thereof against physical damage.
Claim 4
Dependent Claim 23 words
The information card of claim 1, wherein said card base and said support layer of said magnetic sheet are both of vinyl chloride.
Claim 5
Dependent Claim 39 words
The information card of claim 1, wheRein said card base is provided with symbols and letters expressing predetermined information printed on the surface thereof opposite to the surface which is fused to said support layer of said magnetic sheet.
Claim 6
Dependent Claim 23 words
The information card of claim 4, wherein said card base surface is covered with a transparent coating for protection of said printed information.
Claim 7
Dependent Claim 36 words
The information card of claim 5, wherein said protective coating is a film of a thermoplastic material which is laminated onto said card base simultaneously with the lamination of said magnetic sheet and said card base.
