Scroll wheel assembly for scrolling an image in multiple directions
First Claim
1. A computer input device for scrolling an image, the device comprising:
- a housing having an opening;
a finger-engagable control member provided within the housing and having a portion extending through the opening permitting user manipulation thereof, the finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis;
a carriage receiving at least a portion of the finger-engagable control member;
a rotation sensor for sensing rotation of the finger-engagable control member;
an optical tilt sensor for sensing tilting of the finger-engagable control member;
a tilt axle operatively connected to the carriage along the tilting axis, wherein the optical tilt sensor is located at the rear of the finger-engagable control member underlying the tilting axis and includes a light source, a light sensor, and a movable intervening member between the light source and the light sensor, the movable intervening member being operatively connected to the tilt axle; and
a carriage receiving a lower portion of the finger-engagable control member, the carriage further including;
opposing side walls on opposite sides of the lower portion of the finger-engagable control member; and
a gap arranged between the opposing side walls of the carriage and the sides of the lower portion of the finger-engagable control member,wherein tilting the finger-engagable control member causes the finger-engagable control member to move before engaging a side wall of the carriage, and wherein further tilting of the finger-engagable control member engages a side wall of the carriage and causes the carriage to tilt in accordance with the tilting of the finger-engagable control member, andwherein when the finger-engagable control member is rotated, a signal is transmitted to scroll the image relative to a display screen on which the image is displayed in a first scroll direction and wherein when the finger-engagable control member is tilted, a signal is transmitted to scroll the image relative to the display screen on which the image is displayed in a second scroll direction, the second scroll direction being approximately perpendicular to the first scroll direction.

Abstract
A scroll wheel assembly for computer input device having a housing. The scroll wheel assembly includes a housing and an engagable scroll wheel. The scroll wheel is rotatable with a shaft to preferably cause vertical scrolling of an image on a display. The scroll wheel is laterally tiltable relative to the housing and the shaft. A sensor is preferably positioned within the housing for sensing tilting of the rotatable member. In response to sensed tilting movement of the rotatable member, the image is horizontally scrolled, preferably in the direction of the lateral movement. 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.

6. A system comprising:
-
an input device for scrolling an image, the input device including; a housing; and a finger-engagable control member provided within the housing and having a portion extending through the opening permitting user manipulation thereof, the finger-engagable control member being endlessly rotatable about a rotating axis extending within the housing and tiltable about a tilting axis; a carriage receiving at least a portion of the finger-engagable control member; a rotation sensor for sensing rotation of the finger-engagable control member; an optical tilt sensor for sensing tilting of the finger-engagable control member; a tilt axle operatively connected to the carriage along the tilting axis, wherein the optical tilt sensor is located at a rear of the finger-engagable control member underlying the tilting axis and includes a light source, a light sensor, and a movable intervening member between the light source and the light sensor, the movable intervening member being operatively connected to the tilt axle; and a carriage receiving a lower portion of the finger-engagable control member, the carriage further including; opposing side walls on opposite sides of the lower portion of the finger-engagable control member; and a gap arranged between the opposing side walls of the carriage and the sides of the lower portion of the finger-engagable control member, wherein tilting the finger-engagable control member causes the finger-engagable control member to move before engaging a side wall of the carriage, and wherein further tilting of the finger-engagable control member engages a side wall of the carriage and causes the carriage to tilt in accordance with the tilting of the finger-engagable control member; and a controller in communication with the input device configured to generate a signal to scroll an image relative to a display screen on which the image is displayed in a first direction responsive the rotation sensor sensing rotation of the finger-engagable control member and to generate a signal to scroll the image relative to the display screen on which the image is displayed in a second direction responsive to the optical tilt sensor sensing tilting of the finger-engagable control member, the second direction being perpendicular to the first direction. - View Dependent Claims (7, 8, 9, 10, 11)
