Abstract
A scrolling apparatus is disclosed that includes a rotatable scroll wheel and a sensor assembly coupled mechanically through a flexible cable. The sensor assembly has an encoder wheel that rotates in response to rotation of the scroll wheel. The rotational axis of the encoder wheel is axially displaced from the rotational axis of scroll wheel, and the diameter of the encoder wheel may be greater than the diameter of a conventional encoder wheel. The differences in diameter of the scroll wheel and encoder wheel may be utilized to provide the scrolling apparatus with relatively high resolution. In addition, the flexible cable permits the scroll wheel to be mounted within a tilting mechanism.
