Abstract

PURPOSE:To prevent the electrostatic destruction of a pellet and to improve the reliability of a card by short-circuiting respective electrodes electrically when the card is not used and opening the electrodes electrically when the card is used. CONSTITUTION:The pellet 7 is connected electrically to the wiring pattern 13 of a wiring board 12 fitted elastically facing the surface plate 5 of the card 1 by an elastic means 11 across a lead material 9 and a wire 10 which are fixed at one-terminal sides to a support member 8. Further, external electrodes 14 which are exposed out of a hole 4 formed in the card surface plate 5 at the surface side of the wiring board 12 are connected to the wiring pattern 13 through a through hole 15. When the card 1 is not used, the respective external electrodes 14 are short-circuited electrically through the wiring 16 among the electrodes, so a high voltage is prevented from being applied to the pellet 7 owing to static electricity. When the card is used, on the other hand, the external electrodes 14 are pressed toward the card reverse surface by probes 17 to leave the wiring 16, so they are connected to the probes 17 electrically to transmit and receive signals to and from the pellet 7.
