Abstract
Abstract A display unit has a body including a display screen, and a tilt mechanism including a support mounted on the bottom of the body and composed of two partly cylindrical continuous outer surfaces having spaced center axes of curvature, and a base having a plurality of projections on which the outer surfaces are slidably disposed. When the display unit is tilted to change the angle of the display screen with respect to the vertical direction, any point on the display screen is moved back and forth only for a small distance because the center axes of curvature are moved with turning movement of the outer surfaces.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
248 words
A display unit, comprising: a body including a display screen having a length and a width; a tilt mechanism including a support mounted on a bottom of said body, said support including first and second continuous outer surfaces, each in the shape of a segment of a cylinder, and having respective parallel center axes of curvature extending in the direction of said width and spaced apart in a direction perpendicular to said length and said width; a base having a plurality of projections extending in the direction of said length including a first projection terminating at a first apex and a second projection terminating at a second apex spaced from said first apex in said direction perpendicular to said length and said width, said first and second outer surfaces being disposed on said plurality of projections for sliding movement perpendicularly to said direction of said width with said first outer surface being slidably disposed on said first apex and said second outer surface being slidably disposed on said second apex; and means for simultaneously holding said first outer surface in sliding contact with said first apex and said second outer surface in sliding contact with said second apex when said first and second outer surfaces are slidably moved perpendicularly to said direction of said width, whereby said center axes move generally in said direction perpendicular to said length and said width when said first and second outer surfaces are slidably moved perpendicularly to said direction of said width.
Claim 2
Dependent Claim
248 words
A display unit, comprising: a body including a display screen having a length and a width; a tilt mechanism including a support mounted on a bottom of said body, said support including first and second continuous outer surfaces, each in the shape of a segment of a cylinder, and having respective parallel center axes of curvature extending in the direction of said width and spaced apart in a direction perpendicular to said length and said width; a base having a plurality of projections extending in the direction of said length including a first projection terminating at a first apex and a second projection terminating at a second apex spaced from said first apex in said direction perpendicular to said length and said width, said first and second outer surfaces being disposed on said plurality of projections for sliding movement perpendicularly to said direction of said width with said first outer surface being slidably disposed on said first apex and said second outer surface being slidably disposed on said second apex; and means for simultaneously holding said first outer surface in sliding contact with said first apex and said second outer surface in sliding contact with said second apex when said first and second outer surfaces are slidably moved perpendicularly to said direction of said width, whereby said center axes move generally in said direction perpendicular to said length and said width when said first and second outer surfaces are slidably moved perpendicularly to said direction of said width.
Claim 3
Dependent Claim
87 words
A display unit according to claim 1, wherein said support has first and second continuous inner surfaces respectively opposite said first and second outer surfaces, said support having slots defined therein, said slots being spaced apart in said direction of said width, said display unit further comprising bosses mounted on said base and projecting respectively through said slots, and pressers mounted on ends of bosses contacting said first and second inner surfaces so as to hold said first and second outer surfaces against said plurality of projections.
Claim 4
Dependent Claim
26 words
A display unit according to claim 2, including an outer cover mounted on said base in surrounding relation to said plurality of projections and said bosses.
Claim 5
Dependent Claim
34 words
A display unit according to claim 1, wherein said length extends vertically, said width extends horizontally, and said first and said center axes are located below a midpoint of the length of said screen.
Claim 6
Dependent Claim
20 words
A display unit as in claim 1, wherein said first and second continuous outer surfaces are contiguous to each other.
