PROBLEM TO BE SOLVED: To suppress electric impact to a circuit when a card electronic circuit is inserted or removed. SOLUTION: A card detecting part 105 detects insertion of a PC card, an MPU 108 switches one output signal Stime of an output port from an L level to a H level when a prescribed time passes since mounting of the PC card is detected. A switch drive circuit 107 turns on a power supply switch 104 when the signal Stime becomes the H level and immediately turns it off when it detects that the PC card is not mounted. |
