ABSTRACT:
A single-piece component rotatably supports a scroll wheel and includes an integral follower arm extending into a well within which the scroll wheel rotates. Formed on a circumferential surface of the scroll wheel are regularly spaced detents or other structures forming regularly spaced regions of alternating height. Located on an end of the follower arm is a follower which moves in and out of the detents as the scroll wheel rotates, with the arm biasing the follower against movement out of the detents. The carriage may also include pivots for relative movement of the carriage and scroll wheel assembly with respect to a housing, and a tab for actuating a switch.
