Abstract

An input device comprises a housing, and a user-movable roller having an exposed portion exposed from the housing. The roller is rotatable in a first rotational direction to generate first rotational signals. A first user-manipulable button is exposed from the housing for contact by a user and configured to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals when pressed and maintained in a pressed position. In some embodiments, the roller is rotatable in a second rotational direction opposite from the first rotational direction to generate second rotational signals. A second user-manipulable button is exposed from the housing for contact by the user and configured to simulate rotation of the roller in the second rotational direction and generate the second rotational signals when pressed and maintained in a pressed position.

Claims

1. An input device comprising:

a housing;

a user-movable roller having an exposed portion exposed from the housing, the roller being rotatable in a first rotational direction to generate first rotational signals; and

a first user-manipulable button exposed from the housing for contact by a user and configured to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals when pressed and maintained in a pressed position.

2. The input device of claim 1 wherein the roller is rotatable in a second rotational direction opposite from the first rotational direction to generate second rotational signals, and further comprising a second user-manipulable button exposed from the housing for contact by the user and configured to simulate rotation of the roller in the second rotational direction and generate the second rotational signals when pressed and maintained in a pressed position.

3. The input device of claim 2 wherein the roller lies on a plane, and wherein the first and second buttons are disposed along the plane of the roller and on opposite sides of the roller.

4. The input device of claim 3 wherein the first button includes a first head exposed from the housing for pressing by a user and connected to a first extension which moves with the first head when pressed by the user to activate a first switch, the first head being offset from the first extension so as to be disposed adjacent the exposed portion of the roller on one side, and wherein the second button includes a second head exposed from the housing for pressing by a user and connected to a second extension which moves with the second head when pressed by the user to activate a second switch, the second head being offset from the second extension so as to be disposed adjacent the exposed portion of the roller on the opposite side.

5. The input device of claim 4 wherein the first head and the second head each have an arrow shape with a sculpted surface for contact by the user'"'"'s finger.

6. The input device of claim 3 wherein the roller and the first and second buttons are exposed from the housing through a single slot.

7. The input device of claim 3 wherein the first and second buttons are disposed on a pivoting member pivotable relative to the housing around an axis parallel to an axis of rotation of the roller, the pivoting member pivoting in a first direction when the first button is pressed to activate a first switch to generate the first rotational signals, the pivoting member pivoting in a second direction when the second button is pressed to activate a second switch to generate the second rotational signals.

8. The input device of claim 7 wherein the pivoting member is exposed from the housing to form an island having a slot between the first button and the second button through which the roller protrudes.

9. The input device of claim 3 wherein the first button is disposed on a first cantilever member having an end fixed to the housing and is movable relative to the fixed end of the first cantilever member, and wherein the second button is disposed on a second cantilever member having an end fixed to the housing and is movable relative to the fixed end of the second cantilever member.

10. The input device of claim 9 wherein the first and second cantilever members are formed from a single cantilever structure and having a common fixed end which is fixed to the housing.

11. The input device of claim 2 wherein the first button and the second button are attached together by a flexible connecting member prior to assembly into the input device.

12. The input device of claim 1 wherein the first button when pressed and maintained in the pressed position is configured to simulate rotation of the roller in the first rotational direction at a preset rotational rate.

13. An input device comprising:

a user-movable roller configured to be contacted and rotated by a user in a first rotational direction to generate first rotational signals and in a second rotational direction opposite from the first rotational direction to generate second rotational signals;

a first user-manipulable button configured to be contacted by a user;

a second user-manipulable button configured to be contacted by the user;

means for supporting the first and second user-manipulable buttons, to activate a first switch when the first button is pressed and maintained in a pressed position to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals, and to activate a second switch when the second button is pressed and maintained in a pressed position to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals.

14. The input device of claim 13 wherein the first button includes a first head configured to be pressed by a user and connected to a first extension which moves with the first head when pressed by the user to activate a first switch, the first head being offset from the first extension so as to be disposed adjacent the roller on one side of the roller, and wherein the second button includes a second head configured to be pressed by a user and connected to a second extension which moves with the second head when pressed by the user to activate a second switch, the second head being offset from the second extension so as to be disposed adjacent the exposed portion of the roller an opposite side of the roller.

15. The input device of claim 13 wherein the first button and the second button are attached together by a flexible connecting member prior to assembly into the input device.

16. The input device of claim 13 wherein the first button when pressed and maintained in the pressed position is configured to simulate rotation of the roller in the first rotational direction at a preset rotational rate, and wherein the second button when pressed and maintained in the pressed position is configured to simulate rotation of the roller in the second rotational direction at another preset rotational rate.

17. An input device comprising:

a first user-manipulable button configured to be contacted by a user to simulate rotation of a roller in a first rotational direction at a first preset rotational rate and generate first rotational signals when the first button is pressed and maintained in the pressed position; and

a second user-manipulable button configured to be contacted by the user to simulate rotation of the roller in a second rotational direction opposite from the first rotational direction at a second preset rotational rate and generate second rotational signals when the second button is pressed and maintained in the pressed position.

18. The input device of claim 17 wherein the first button and the second button are structurally connected to be spaced from one another to position the roller therebetween.

19. The input device of claim 17 further comprising means for supporting the first and second user-manipulable buttons, to activate a first switch when the first button is pressed and maintained in a pressed position to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals, and to activate a second switch when the second button is pressed and maintained in a pressed position to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals.

20. The input device of claim 17 wherein the first preset rotational rate and the second preset rotational rate are equal.
