Abstract

A computer input device having a housing and a finger-engagable scrolling device. A portion of the scrolling device is endlessly rotatable about a first axis to preferably cause vertical scrolling of an image on a display. The scrolling device is pivotally movable relative to the housing about a second axis perpendicular to the first axis. The finger-engagable scrolling device may contain rotation sensor within a scroll wheel assembly. The finger-engagable scrolling device may also contain lateral arms extending laterally from the finger-engabable scrolling device.

Claims

1. An input device for scrolling an image relative to an image display screen, said device comprising:

a housing having at least one opening;

a finger-engagable control member provided within said housing and having a portion extending through said opening permitting user manipulation thereof, said finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis, the finger-engagable control member including an inner radial surface defining a radial edge of a central hollow internal area of the endlessly rotatable finger-engagable control member;

a rotation sensor positioned within the central hollow internal area of the endlessly rotatable finger-engagable control member configured to sense rotation of the finger-engagable control member; and

a tilt sensor configured to sense tilting of the finger-engagable control member.

2. The device of claim 1 wherein when the finger-engagable control member is rotated, a signal is transmitted to scroll the image in a first scroll direction and wherein when the finger-engagable control member is pivoted, a signal is transmitted to scroll the image in a second scroll direction, the second scroll direction being perpendicular to the first scroll direction.

3. The device of claim 1 wherein the finger-engagable control member further includes a lateral aspect defining a lateral edge of the central hollow internal area.

4. The device of claim 1 wherein the rotation sensor includes a disc-shaped member.

5. The device of claim 4 wherein the disc-shaped member is stationary when the endlessly rotatable finger-engagable control member is rotated.

6. The device of claim 1 wherein the pivoting axis is perpendicular to the rotating axis.

7. The device of claim 1 wherein the finger-engagable control member further includes a first lateral arm extending laterally from a first lateral side and a second lateral arm extending laterally from a second lateral side, the first lateral arm and the second lateral arm being coplanar on a plane that is parallel to the rotating axis.

8. The device of claim 7 wherein pivoting of the finger-engagable control member causes a corresponding movement of the first and second lateral arms in the plane.

9. The device of claim 7 wherein the plane is further parallel to the pivoting axis.

10. The device of claim 9 wherein the plane intersects the finger-engagable control member.

11. The device of claim 10 wherein the tilt sensor further includes a first contact switch at a first lateral side of the finger-engagable control member along the rotating axis of the finger-engagable control member and a second contact switch at a second lateral side of the finger-engagable control member along the rotating axis of the finger-engagable control member.

12. The device of claim 11 wherein the first lateral arm is capable of contacting the first contact switch when the finger-engagable control member is pivoted in the direction of the first contact switch and the second lateral arm is capable of contacting the second contact switch when the finger-engagable control member is pivoted in the direction of the second contact switch.

13. A computer input device for scrolling an image, said device comprising:

a housing having at least one opening;

a finger-engagable control member provided within said housing and having a portion extending through said opening permitting user manipulation thereof, said finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis, the finger-engagable control member further including a first lateral contact arm extending laterally from a first lateral side and a second lateral contact arm extending from a second lateral side, the first lateral contact arm and the second lateral contact arm being generally horizontal;

a rotation sensor for sensing rotation of the finger-engagable control member; and

a tilt sensor for sensing tilting of the finger-engagable control member, the tilt sensor having a first contact switch at a first lateral side of the finger-engagable control member along the rotating axis of the finger-engagable control member and a second contact switch at a second lateral side of the finger-engagable control member along the rotating axis of the finger-engagable control member,

wherein the first lateral contact arm is configured to contact the first contact switch when the finger-engagable control member is pivoted in the direction of the first contact switch and the second lateral contact arm is configured to contact the second contact switch when the finger-engagable control member is pivoted in the direction of the second contact switch.

14. The device of claim 13 wherein when the finger-engagable control member is rotated, a signal is transmitted to scroll the image in a first scroll direction and wherein when the finger-engagable control member is pivoted, a signal is transmitted to scroll the image in a second scroll direction, the second scroll direction being perpendicular to the first scroll direction.

15. The device of claim 13 wherein the first lateral contact arm is capable of contacting the first contact switch when the finger-engagable control member is tilted in the direction of the first contact switch and the second lateral contact arm is capable of contacting the second contact switch when the finger-engagable control member is tilted in the direction of the second contact switch.

16. The device of claim 13 further comprising a carriage including a first lateral side and a second lateral side, the carriage housing at least a portion of the finger-engagable control member and being stationary when the finger-engagable control member is rotated.

17. The device of claim 16 wherein the first lateral side of the carriage is adjacent and parallel to the first lateral aspect of the finger-engagable control member and the second lateral side of the carriage is adjacent and parallel to the second lateral side of the finger-engagable control member, the first lateral arm being connected to the approximate midpoint of the first lateral side of the carriage and the second lateral arm being connected to the approximate midpoint of the second lateral side of the carriage and extending laterally from the carriage.

18. A computer input device for scrolling an image, said device comprising:

a housing having at least one opening;

a finger-engagable control member provided within said housing and having a portion extending through said opening permitting user manipulation thereof, said finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis and including a first lateral contact arm extending laterally from a first lateral side and a second lateral contact arm extending from a second lateral side, the first lateral contact arm and the second lateral contact arm being generally horizontal;
