SOLUTION: The device body is provided with a front part link 13 and a rear part link 14 relatively rotatably by way of a link shaft 11, the end part of the front part link 13 is freely movably linked to a fixed guide 16, an end part of the rear part link 14 to a movable guide 20 integrated with a display unit respectively. Between both of the links 13 and 14 is provided a lock spring 23 that acts so that a display unit does not move backward at the time of operating the display unit and it can be moved when closed, and improvements of the opening/closing performance and the stability of the operation are attained.</p> |
