FUNCTION ENHANCEMENT UNIT FOR ELECTRONIC DEVICE

摘要

An electronic apparatus is received on the front surface of an enclosure (12). A connector (14) is connected to the electronic apparatus. When the electronic apparatus is to be demounted, an operating body (17) is pulled out from a retract position toward a pulled-out position. A movable member (24) moves from a first position to a second position. The movable member (24) at the second position serves to protrude lifting members (16, 16) out of the front surface of the enclosure (12), so that the lifting members urge the electronic apparatus upward. The connector (14) is disconnected from the electronic apparatus. The movable member (24) allows the movement of the operating body (17) from the pulled-out position to the retract position while the movable member (24) stays at the second position. The operating body (17) returns to the retract position while the disconnection is maintained between the connector (14) and the electronic apparatus. When the electronic apparatus is lifted off, for example, a wire of the electronic apparatus is prevented from engagement with the operating body (17). The extension unit (11) is prevented from a fall resulting from the engagement. The extension unit (11) is prevented from getting damaged.
