Abstract
A portable communication apparatus includes a first unit having at least a display section and a second unit having at least a main operation section, which are coupled by a slide coupling and are freely slidable in a longitudinal direction between a retracted state and an extended state. The first unit and the second unit are urged by an urging member in an extension direction and are releasably locked by a releasable lock mechanism in the retracted state. The locking is released by a predetermined operation. An optical aperture for optical function is provided in one of surfaces of the first and second units that face one another in the retracted state. The optical function section is made operable when the first and second units are positioned in the extended state.
