  • Display Panel Driving Mechanism for Electronic Device
    Publication number: 20080094382
    Abstract: A display panel driving mechanism for electronic device supports a lower side of a display panel (1), which is arranged on a front plane of an electronic device, to be freely turned around a first shaft (5a) which moves by following a slider (4) driven in to and fro directions. The mechanism shifts a second shaft (9a), which is provided on a member (9) attached on an upper side of the display panel (1), along a guide groove (2a) provided on a member (2) fixed to a case. In a shifting initial period of the first shaft (5a), the first shaft (5a) is shifted in a rear direction from an initial status, in which the display panel (1) is at a position where it covers the front plane of the electronic device by not inclining and the front plane of the display panel is inclined to face down. In the shifting initial period, the first shaft (5a) is permitted to shift to the rear and to an upper part.
