<p>PURPOSE:To improve a connecting environment and to guarantee the operation of an IC card by causing the length of a pin in a connector to be three steps and gradually connecting an electronic equipment main body and the IC card with the three types of timings. CONSTITUTION:When an IC card 200 is inserted into a male connector 3 of an electronic equipment 100, at first, a pin 6a and a inserting port 16a are electrically connected. At such a time, when there is potential difference between the main body 100 and a grand level in the card 200, a charge to correspond to the potential difference is discharged namely, a current flows between the both of them. Since the current at such a tie flows through resistors 5 and 15, the potential different between the both of than does not go to be '0' immediately but the difference proceeds at a comparatively low speed. In a process to further insert the card 200, the grand level of the both go to be almost same. Thus, this time, in a step to insert pins 6b and 6b' to inserting holes corresponding to a male connector 13, grands 4 and 14 between the both go to be a connecting condition for the first time and the wholly same level.</p> |
