Abstract
In an electronic apparatus with a separably combining main body and expander, a pair of movable claws which are interlocked with an opening/closing lever are provided on an upper surface of the expander and a pair of fixed claws are provided on the opposite side of the opening/closing lever. A connecting connector is arranged at an intermediate position of the pair of movable claws. A retaining lever for blocking an opening of the opening/closing lever in a closed state of the opening/closing lever is provided. A first detector detects an opening/closing state of the opening/closing lever and a second detector detects the position of the retaining lever. A connecting state of the main body and the expander is synthetically discriminated on the basis of signals from the two detectors and a connection signal of the connector for connecting the main body and the expander.
