PROBLEM TO BE SOLVED: To shut off a card or a card insertion port from outdoor air and to protect it at the time other than the insertion/detachment of the card by providing a prescribed case driving mechanism at the time of inserting/detaching a card case to/from a receiver. SOLUTION: A card case driving mechanism 64 moves the card case 50 back and forth toward a card case slot 59. When a user pushed up a sliding type door member 60 to an upper side so as to insert the card 78 to the receiver, a driving rack gear 64c makes the case 50 advance while being moved forwards by a coil spring 70 and the card slot 44 is projected through the slot 59 to the outside of a receiver housing. At the time of the completion of card insertion, when the door member 60 is released, the member 60 is automatically lowered and simultaneously, the gear 64c elastically retreats and moves the case 50 to the retreat position. As a result, the card 78 and the case 50 are shut off from the periphery by the door member 60. |
