Patent ID: 7724533

Claim:
An electronic apparatus comprising: an apparatus body including a pair of support members, the support members respectively defining surfaces opposed to each other; a removable unit supported between the surfaces of the support members, the removable unit defining a bottom surface located at a position adjacent to a bottom surface of the apparatus body; parallel guiding rails attached to either of opposite sides of the removable unit or the surfaces of the support members; parallel receiving grooves formed on a reminder of the opposite sides of the removable unit and the surfaces of the support members, the parallel receiving grooves receiving corresponding ones of the parallel guiding rails, respectively, a predetermined gap or gaps being defined adjacent to each of the guiding rails in the corresponding one of the parallel receiving grooves for allowing the opposite sides of the removable unit to change attitude relative to the surfaces of the support members; a first pad disposed on the bottom surface of the apparatus body; a pair of second pads disposed on the bottom surface of the removable unit at positions spaced by a predetermined interval; a protruding piece disposed in each of the parallel receiving grooves, the protruding piece being engaged with a rear end of a corresponding one of the parallel guiding rails, respectively received in the parallel receiving grooves, for keeping attachment of the removable unit to the apparatus body, the protruding piece being configured to withdraw from a corresponding one of the parallel receiving grooves; and an elastic member interposed between the protruding piece and either of the removable unit and the support members, that holds or hold the parallel receiving grooves, the elastic member exerting an elastic force to the protruding piece to hold the protruding piece in the parallel receiving grooves.
