<P>PROBLEM TO BE SOLVED: To provide a portable terminal device capable of easily deciding a position desirable for non-contact IC communication. <P>SOLUTION: This portable terminal device having a non-contact IC card function is provided with at least one pair of a projection part 51 and a recess part 52 around a position 53 matching the center of a built-in non-contact IC antenna on the outside surface of a casing 50. During use of the non-contact IC card function between the portable terminal devices, the portable terminal devices are overlapped to each other to be positioned so that the projection part 51 and the recess part 52 in one portable terminal device are fitted to the recess part 52 and the projection part 51 in the other portable terminal device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
