Abstract
A rotary detent mechanism comprises a first wheel having a plurality of radially extending lobes circumferentially spaced about its axis of rotation. Second and third wheels each having outwardly extending ribs spaced for driving engagement with the lobes of the first wheel are positioned on opposite sides thereof. The ribs of the second and third wheels are related to the lobes of the first wheel such that driving rotation between the first wheel and the second and third wheels requires relative movement of the wheels toward and away from one another in a direction perpendicular to the axis of rotation of the first wheel. A drive member is provided for selectively rotating one of the wheels and a spring assembly is provided for biasing the wheels toward one another in a direction perpendicular to the first axis.
