Abstract

A thumbwheel input device oriented on an incline and comprising a wheel such that a first input is generated by rotation of the wheel about its axis, and a holder also having an axis of rotation and a portion thereon to receive the wheel whereby a second input is generated by rotation of the holder about the second axis.

Claims

1. A thumbwheel input device for a mobile device having a printed circuit board therein, the thumbwheel input device comprising:

a. a wheel having a first axis of rotation, the wheel being inclined at a first angle between 0 and 45 degrees, relative to the printed circuit board, whereby a first input is generated by rotation of the wheel about the first axis; and

,

b. a holder having a second axis of rotation substantially parallel to the printed circuit board, said holder holding said wheel such that the wheel and the first axis are able to rotate around the second axis through a second angle, whereby a second input is generated by rotation of the holder about the second axis.

2. A thumbwheel input device of claim 1 further comprising:

c. a first detection means for detecting input about the first axis; and

,

d. a second input detection means for detecting input about the second axis.

3. A thumbwheel input device of claim 2 wherein a portion of the wheel is partially protruding outside a housing enclosing the thumbwheel input device so as to permit the receiving of the first and second inputs.

4. A thumbwheel input device of claim 2 wherein the first input detection means is a rotating encoder switch.

5. A thumbwheel input device of claim 2 wherein the second input detection means is a tactile switch.

6. A thumbwheel input device of claim 1, wherein the first angle is between 25 and 45 degrees, relative to the printed circuit board.

7. A thumbwheel input device of claim 1, wherein the first angle is between 35 and 45 degrees, relative to the printed circuit board.

8. A thumbwheel input device of claim 1, wherein the first angle is 45 degrees, relative to the printed circuit board.
