Abstract
Abstract A portable computer includes a housing and a keyboard unit mounted on the housing. A display unit is mounted on the housing to be movable between a closed position wherein the keyboard unit is covered by the display unit and a desired opened position wherein the keyboard is exposed. A latch mechanism for locking the display unit in the closed position is provided at the display unit. The mechanism includes a pair of latch hooks rockable between a latch position wherein each hook engages the housing and a release position wherein each hook is disengaged form the housing, and an interlocking member movable in interlock with the movement of the latch hooks. When a dial key attached to the display unit is turned on, the movement of the interlocking member is restricted by the key and the hooks are locked in the latch position.
