Abstract

A motion picture projector with a rapid rewind system for returning a projected reel of film from the takeup reel back onto the supply reel at a substantially faster rate than the film is transported during projection. The rapid rewind system includes a drive train engageable with the supply reel to rotate the supply reel in a reverse direction at a substantially faster rate. An actuator is connected to the rapid rewind drive train to disengage the projection drive train and engage the rapid rewind drive train with the supply reel in response to movement of the takeup reel from its generally horizontal project position to a generally vertical rewind position.
