ABSTRACT:
A motion picture projector having a forward and reverse film transporting drive, an assembly for sensing a predetermined film tension condition and a mode controller for selecting various operational modes is provided with a control for selectively actuating a rewind mode of operation at a predetermined film tension condition.
The selectively actuated rewind control arrangement includes a controller conditioner mechanism that is responsive to film tension and effective to position the controller from a predetermined projector operating mode such as a normal forward mode to a predetermined operating mode such as still when the predetermined film tension condition is sensed. A rewind mode actuator mechanism responsive to the controller conditioner mechanism is provided to control the film transporting drive in the rewind mode upon the operation of the controller conditioner mechanism.
The rewind mode actuator mechanism in one arrangement includes a translating member for converting a linear displacement of the controller conditioning mechanism to a rotational movement which is connected to rotate a coupling rod carrying a displacing actuator. The displacing actuator displaces a reverse drive actuator in the film transporting assembly to condition it in a rewind mode.
