用する装置に設けてもよい。According to the above configuration, the reverse insertion of the IC card is allowed, and the problem of reverse insertion is solved by electrically processing the problem. In other words, when inserting the card in reverse, the connected terminals are different from the original terminals, so there are problems such as ■ Power input to the IC card and grounding are not performed, ■ Address lines and data lines are not in the desired positions. . Therefore,
First, by arranging two sets of power input terminals and ground terminals at point-symmetrical positions, power input can be performed in both forward and reverse directions. In addition, a means for detecting the front and back sides of the IC card is provided, and based on the detection output, a data selector exchanges data between terminals that are in a point-symmetric positional relationship with respect to the center point of the terminal arrangement section, and a predetermined address line is set for both forward and reverse directions. , so that it can be connected to the data line. Note that such a function may be provided within the IC card or may be provided in a device that uses the IC card.
