Abstract: An edge loading cassette holder/loader utilizes an improved ejector/release control arrangement wherein the cassette is loaded narrow end first through a loading receiver opening into a holder/loader platform. The control arrangement includes a first pivotally mounted control arm that is biased to pivot the arm to partially eject the cassette for removal and that also functions as a release control member for the platform. A second pivotally mounted control arm that moves with the first arm and functions as a release member for the platform is also provided. The platform is pivotally movable between an upper loading position and a lower operative position wherein the cassette hub sprockets are engaged by transport drive spindles. The platform is biased to the lower operative position and is moved to the upper loading position by the second control arm.

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.

Abstract: A projector with forward and reverse film drive assemblies and a mode controller assembly for selecting operational modes is provided with a control to selectively stop film transporting when a predetermined film tension occurs. The mode controller assembly is manually shiftable to position the film transport stopping control to reset the control.The control uses a selectively responsive transmitting assembly arranged to transmit a predetermined film tension from a sensor to a reset member when the mode controller assembly is in selected modes as normal forward and reverse. In other modes as fast forward, pause, still and rewind, the selectively responsive assembly is provided with a release locking assembly to prevent transmission of the predetermined film tension condition to the reset member.The selectively responsive assembly has a pivotal release arm that controls the position of the reset member when the predetermined film tension condition occurs.
