Abstract
A portable terminal computer is adapted for connection to an optional unit and a host computer. The optional unit (6) includes a connector (15) for electrical connection to the main body (1) of the portable computer, guides (8), a lock pawl (9) for coupling the optional unit (6) to the main body (1), and a lock release (17). The main body (1) includes guide inserting slots (10) in which guides (8) are inserted, a pawl inserting slot (11) in which the lock pawl (9) is inserted, and an engagement member (30) for engaging the lock pawl (9). The above-described structure allows smooth attachment and detachment of the main body (1) to and from the optional unit (6), thereby preventing malfunction.
