Abstract
Abstract An apparatus for providing tilting and rotational movements of a display panel. The apparatus includes a first device for tilting the display panel toward or away from a viewer and a second device for rotating the display panel in sidewise directions. The first device has a supporting member for supporting the display panel and a pair of connecting members for connecting the display panel with the supporting member. The connecting members have spring loaded balls for rotatable engagement of the supporting member with the display panel. The second device has a pinion for driving the display panel and a power conveying unit for conveying the power from the driving pinion. The power conveying unit has a rack divided into a first gear portion and a second gear portion engaged with the driving pinion, and a driven pinion coupled to the supporting member and having a gear portion engaged with the first gear portion of the rack.
