Scrolling apparatus providing multi-directional movement of an image

An apparatus for scrolling an image in multiple directions relative to a display screen, said apparatus comprising:

• a housing having at least one aperture therein;
• a rotatable member at least partially located within the housing, a portion of the rotatable member protruding outward through the aperture;
• and
• a depressible and ring-shaped actuator extending around the rotatable member and positioned adjacent to the rotatable member.

An apparatus for scrolling an image in multiple directions relative to a display screen, said apparatus comprising:

• a housing having at least one aperture therein;
• a rotatable member at least partially located within the housing, a portion of the rotatable member protruding outward through the aperture;
• and
• a pair of depressible actuators extending around opposite sides of the rotatable member and positioned adjacent to the rotatable member.

An apparatus for scrolling an image in multiple directions relative to a display screen, said apparatus comprising:

• a housing having at least one aperture therein;
• a rotatable member at least partially located within the housing, a portion of the rotatable member protruding outward through the aperture;
• at least one depressible actuator extending around the rotatable member;
• and
• indicia located on the actuator and pointing radially outward relative to the rotatable member.

An input device for moving a cursor relative to a display screen, the input device comprising:

• a housing having at least one aperture therein;
• a rotatable member at least partially located within the housing, a portion of the rotatable member protruding outward through the aperture;
• at least one depressible actuator extending around the rotatable member and positioned adjacent to the rotatable member;
• and
• a primary key and a secondary key located on opposite sides of the actuator.

A method of scrolling an image in relation to a display screen, the method comprising steps of:

• providing an input device having a rotatable member and an actuator;
• configuring the input device to transmit a first signal to a host computer when the rotatable member is rotated and to transmit a second signal to the host computer when the actuator is depressed;
• and
• incorporating data into the signal that directs the host computer to scroll the image.
