The chip contactor 70 uses a chip contactor module of an actual card terminal composed of eight contact terminals to maintain the same condition that may occur when the card contactor is used in an actual card terminal. In order to install a separate dummy terminal 92 can be used. In such a case, a program for checking the dummy terminal 92 in conjunction with the personal computer 94 is required. The contact terminal of the chip contactor 70 may wear down with the surface of the chip on board as time elapses when it is used for a long time, and thus the reliability thereof may be degraded. It is desirable to do a test. To this end, the chip contactor part 70 is fixed to be detachable to the mother by enabling replacement.

In addition, the chip contactor 70 is impacted when the contactor of the card or the chip contactor 70 is not damaged by excessive shock when the card contact unit 70 reciprocates by the card driver 60 into which the card is inserted.
