Patent ID: 8482524

Claim:
An input device for an electronic device, the input device comprising: a source of light emitting a light beam in a first direction, a reflecting member for reflecting said light beam, tilting means for allowing tilting of the reflecting member around at least one axis transverse to said first direction, at least one detector that detects the reflected light beam and outputs an electric signal corresponding to a light intensity of the detected light beam in a second direction, in which the light beam is reflected, and an electronic circuit adapted to derive a position signal from the at least one electric signal, wherein said tilting means comprises: a first bearing having at least one convex surface and at least one concave surface cooperating with each other in a sliding relationship; and a second bearing having at least one convex surface and at least one concave surface cooperating with each other in a sliding relationship, wherein said first bearing and said second bearing comprise a common bearing member, said common bearing member carrying said concave surface of said first bearing cooperating with said convex surface arranged on a portion of said reflecting member and further carrying said convex surface of said second bearing cooperating with said concave surface arranged on a portion of said reflecting member thus enabling said tilting of said reflecting member.
