Abstract
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.
