Claim:
An electronic device comprising: first and second housings, wherein one of first and second housings comprises a keyboard and the other housing comprises a display screen; a pair of cam assemblies each having first and second connection parts that are rotationally connected, wherein each cam assembly is configured so that the first and second connection parts tilt relative to each other responsive to rotation of one relative to the other, wherein the first connection parts of both cam assemblies are connected to spaced apart locations on the first housing; a pair of actuator arms that are connected on one end to spaced apart locations on the second housing and are connected on the other end to different ones of the second connection parts of both cam assemblies, wherein relative movement of the first and second housings rotates the first connection part relative to the second connection part of both cam assemblies and tilts the first housing relative to the second housing; and wherein the first connection part of each cam assembly has a cylindrical portion with a sloped face; the second connection part of each cam assembly comprises a flange that presses against and rides along the sloped face of the first connection part as the first connection part is rotated relative to the second connection part to tilt the first connection part relative to the second connection part and tilt the first housing relative to the second housing.
