  • Patent number: 7775816
    Abstract: An electronic device case structure includes a case body, a pivoting seat, a pushing member, and a driving member. An accommodating slot is formed on the case body for a peripheral device to be inserted therein. The case body has a disposition hole communicating with the accommodating slot and an internal space of the case body. The pivoting seat is disposed in the case body, and the pushing member is pivoted to the pivoting seat. The pushing member has a pushing segment, protruding in the accommodating slot through the disposition hole and a connecting segment. The driving member includes a coupling end connected to the connecting segment and an operation end, The operation end is to be pressed to make the driving member move inwards, so as to have the pushing segment to move towards the outside of the accommodating slot, thereby pushing and ejecting the peripheral device.
