    • 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.

    • A motion picture projector is provided with a manually shiftable mode controller assembly for selecting various operational modes and apparatus for the automatic threading and rewinding of film. The operative mechanical components of the projector are mounted on a unitarily molded housing including molded structures and portions that independently and cooperatively with other control assemblies and interfitting structures provide features and improved operational characteristics. The molded housing interfits with a take-up reel cover, a control assembly cover and a rear cover that rotatably engages a carrying handle. Structure to define a film path, an automatic threading assist structure, a film speed detent structure and a position defining structure for the mode controller assembly are also provided by and integrally molded with the housing.
