Abstract

PURPOSE:To prevent a display part from being opened inadvertently when the grip of a portable electronic apparatus is lifted by a structure wherein a stopper is shifted in the direction different from the rotating direction of a cover body and engaged with the body when the portable electronic apparatus is transported while being suspended. CONSTITUTION:When a grip 3a is lifted with a body 1 and a display part 4 being closed, the grip 3a is bent gravitationally by the weight of the body 1 and the display part 4 and a core member 3b movable freely in the horizontal direction is translated in the central direction. A holding lever 9 coupled through a pin 10 with a coupling hole of the core member 3b is then rotated and the click is engaged with an engaging hole 4a at the display section 4 which is thereby held in closed state automatically. When the grip is released after transportation, the core member 3b slide resiliently outward to the original position and the holding lever 9 rotates reversely to disengage the click which is then contained in the body 1 thus unlocking the apparatus. This structure prevents the display part 4 from being opened due to inadvertent touching of a finger to an open/close lever when the grip is lifted.
