Abstract
A rotary stop mechanism (10) in accordance with the invention stops rotation of a shaft (12) at a fixed angular position in response to relative rotation of first and second gears (14, 16) on the shaft through a fixed angle which causes a stop pin (26) to project axially from one of the gears to engage a stop (32) when the relative angular rotation occurs by utilizing a control track (34) having a section (48) varying in axial position with respect to the axis of rotation to cause the stop pin to project axially to a position at which the stop pin hits the stop when the gear carrying the stop pin rotates to a fixed angular position.
