Abstract:
A card slot door locking mechanism comprising:a pair of doors, each of said pair of doors being rotatable between a closed position to close a card slot and an open position to allow a removable card to be inserted into said card slot, and being biased to said closed position; a pair of open guide surfaces, each of said pair of open guide surfaces being formed on each respective door of said pair of doors so that said pair of doors concurrently rotate to said open position when said pair of open guide surfaces are concurrently pushed by said removable card, said pair of open guide surfaces being apart from each other in a lengthwise direction of said card slot; and a pair of barrier surfaces, each of said pair of barrier surfaces being formed on each respective door of said pair of doors, positioned between said pair of open guide surfaces in said lengthwise direction of said card slot, so that at least one of said pair doors is prevented from rotating toward said open position when at least one of said pair of barrier surfaces is pushed by an object other than said removable card without pushing said pair of open guide surfaces concurrently.
