<p>PURPOSE:To safely insert/extract an IC card in an information processor to which the IC card is loaded. CONSTITUTION:An information processing function part 1 is a main necessary part realizing the scheduled operation of the processor, and a card I/F 2 electrically connects the IC card 3 with the information processing function part 1. Feed for the information processing function part 1 is controlled by a first switch means 4a, and feed for the card I/F 2 and the IC card 3 is controlled by a second switch means 4b. Information exchange between the information processing part 1 and the storage medium 3 is exchanged through a data bus 5. Feed for the information processing function part 1 and feed for the card I/F 2 can independently be controlled.</p> |
