An IC card loading detecting apparatus utilizing an input/output terminal portion of an IC card which houses therein a central processing unit (CPU) and including a simple detecting means provided on an interface unit of a terminal equipment so that the IC card loading detecting apparatus can be miniaturized, particularly, reduced in thickness. A ground contact (6e) and a detection sensor contact (7) provided on an interface portion (6) of a terminal equipment (4) are brought in contact with a ground terminal (2e) of an input/output terminal portion (2) of an IC card (1) so as to produce a time difference between the contacts with respect to the insertion direction of the IC card (1). The off-states of the ground contact (6e) and the detection sensor contact (7) are output through a TTL (transistor logic) buffer (9) to a CPU circuit of a host as a high "H" level signal to thereby detect whether the IC card (1) is loaded onto the terminal equipment (4). <IMAGE> |
