Apparatus for manufacturing resonant tag
First Claim
1. An apparatus for manufacturing a resonant tag having a resonant circuit including capacitor electrodes formed at opposing positions on the two surfaces of a substantially flat insulating material, and an inductor element, one of said capacitor electrodes extending beyond the opposing electrode said apparatus for manufacturing a resonant tag comprising:
- heat press means for pressing said insulating material from the side of the larger electrode to adjust the tuning frequency of said resonant circuit by thinning out the thickness of the pressed portion of the insulating material; and
a base, having a surface larger than said heat press means, for receiving the pressure of the heat press means; and
wherein the base comprises at least a first layer and a second layer, the first layer being formed of a sheet material having a rigidity greater than that of the second layer.

Abstract
A resonant tag is manufactured in the manner described below: a conductive thin film is formed to a predetermined thickness on two surfaces of an insulating thin film. Thereafter, a conductive pattern, composed of an inductor element and a capacitor element corresponding to a resonant frequency of a resonant circuit, is printed on a surface of one of the conductive thin films, and a conductive pattern, composed of a capacitor element corresponding to the resonant frequency of the resonant circuit, is printed on a surface of the other insulating thin film at a position which faces the capacitor element formed on one of the conductive thin films using an ink which resists etching. A non-printed portion of the conductive thin films is removed by etching to form a resonant circuit pattern. Thereafter, a portion of the insulating thin film, which corresponds to the capacitor element pattern, is thinned to a desired thickness by pressing a heating/pressing member heated to a predetermined temperature against that portion under a predetermined pressure for a predetermined period of time.
