PROBLEM TO BE SOLVED: To resolve a problem that a conventional card-like medium may be stolen because it is simply attachable to and detachable from a slot of a computer. SOLUTION: When a PC card 10 is mounted in the slot 21 of a computer 20, mounting holes 14 and 15 are formed on the rear side 13 exposed outside and an antitheft wire 30 mounted on a computer-side mounting part 24 is attached to the mounting holes 14 and 15 so that the PC card 10 can not be detached from the computer 20, thereby preventing the PC card 10 from being stolen. By mounting a fitting M to the mounting hole 15, the directivity characteristic of a transmission antenna 17 can be improved. |
