Abstract

A computer input device having a housing and an engagable scroll wheel. The scroll wheel is rotatable about an axis to preferably cause vertical scrolling of an image on a display. The rotatable member is laterally movable relative to the housing. A sensor is preferably positioned within the housing for sensing lateral movement of the rotatable member. In response to sensed lateral movement of the rotatable member, the image is horizontally scrolled, preferably in the direction of the lateral movement. The scrolling speed can be affected relative to the amount of displacement of the rotatable member and/or the amount of time that the rotatable member is displaced a predetermined amount. The computer input device having the rotatable member may take the form of a keyboard, a mouse, a trackball device, or another type of computer input device.

Claims

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

a housing having at least one opening; and

a scroll wheel assembly provided within said housing, said scroll wheel assembly including a rotatable member that is rotatable about a first axis extending within said housing and slideably movable about a second axis within said opening, said first axis and said second axis being perpendicular to each other; and

a movement sensing system configured to sense rotational movement of said rotatable member about said first axis for scrolling the image in a first scrolling direction;

a plurality of sensors for detecting tensile extension force to the sensors and the force responsive to, the sliding movement of said rotatable member about the second axis for scrolling the image in a second scrolling direction perpendicular to the first scrolling direction, the sensors resilient extensible;

wherein the image is operable to scroll in the second direction responsive to the detected extension force.

2. The input device according to claim 1, wherein said rotatable member is laterally movable along said first axis within said opening.

3. the input device according to claim 1, wherein said rotatable member includes a finger-engagable control member including raised side edges and a concave recessed center section.

4. The input device according to claim 1, wherein the scroll wheel assembly includes a shaft member extending along said first axis and said rotatable member is slideably coupled to said shaft member, said rotatable member being slideably movable about said shaft member.

6. The input device according to claim 4, further including a shaft supporting system that permits said shaft member and said rotatable member to float within said housing.

7. The input device according to claim 6, wherein said shaft supporting system includes a pair of arms, each said arms being positioned for supporting a portion of said shaft, and a resilient member positioned between each said cradle and said housing for supporting a respective one of said cradles within said housing.

8. The input device according to claim 1, wherein said scroll wheel assembly includes a bracket that slides when rotatable member is moved laterally relative to said opening.

5. The input device according to clam 1, wherein said scroll wheel assembly includes a support member configured for supporting said shaft, said support member being slideably movable about said second axis.
