情報が消去されてしまうという問題点があつた。Since the conventional IC card was configured as above, −
When a frequency that resonates with the natural frequency of the electrode contacts is applied to the IC card, -the electrodes vibrate at the same time-the electrode contacts become non-contact and the power supply to the electric circuit is cut off, and the stored information is erased. There was a problem that it would end up.
この発明は上記のような問題点を解決するためになされ
たもので、ICカードにある振動数が加つた場合接触子が
電池より離れ電気回路への電力供給を遮断することのな
いICカードを得ることを目的とする。The present invention has been made to solve the above problems, and an IC card in which the contact is separated from the battery and the power supply to the electric circuit is not interrupted when a certain frequency is applied to the IC card. The purpose is to get.
この発明に係るICカードは電池の片方の極に２つの接触
子を有し、この接触子の幅、厚さは同一で長さが異なる
ようにしたものである。The IC card according to the present invention has two contacts on one pole of the battery, and the contacts have the same width and thickness but different lengths.
この発明における接触子は接触子の長さが異なることに
よつて固有振動数が異なり、ICカードに加わる振動数に
より片方の接触子が共振している時、他方の接触子は共
振をせず電池に接触したままとなる。The natural frequency of the contact in this invention is different due to the different length of the contact, and when one contact resonates due to the frequency applied to the IC card, the other contact does not resonate. It remains in contact with the battery.
以下、この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.

電極接触子である。FIG. 1 is a perspective view of a contact portion of an IC card showing an embodiment of the present invention, wherein reference numerals (1) to (5a) and (6) to (6) in FIG.
(9) is exactly the same as the conventional one. In the figure, (5b) is different in length from the electrode contactor (5a).
It is an electrode contactor.

れる。In the IC card configured as described above, when a natural frequency of one of the -electrode contacts (5a) and a resonance frequency are applied, the -electrode contact (5a) is separated from the -pole (2) and is not in contact. It becomes a state. However, since the other-electrode contactor (5b) does not resonate, it is not separated from the pole (2), and power is supplied to the electric circuit through the electrode contactor (5b). In addition, when a frequency that resonates with the -electrode contactor (5b) is applied to the IC card, the other -electrode contactor (5a) is not separated from the -pole, but passes through the -electrode contactor (5a) and the electric circuit. Is supplied with power.
なお、上記実施例では−電極接触子の長さを異なる場合

ようにすることによりある振動数がICカードに加わつて
も電池との接触は保持され電気回路への電力供給遮断を
防止できるという効果がある。As described above, according to the present invention, by making the shape of the contacts different, even if a certain frequency is applied to the IC card, the contact with the battery is maintained and the power supply to the electric circuit can be prevented from being cut off. There is.
