Abstract
Abstract A portable compact case includes a rectangular box-like base section and a set of two cover members which seat on the base section and define corresponding front and rear compartments. A standard carousel-type film slide projector is positioned within the rear compartment, and a collapsible viewing hood assembly is located within the front compartment. The front compartment also encloses a standard cassette-type tape recorder in addition to an electronic synchronizing unit which controls the advancement of the slide projector in response to inaudible signals on the tape cassette. The recorder is removable from the front compartment through a door opening within the front wall of the case, and a speaker is positioned adjacent the front wall in back of an adjustable mirror. The viewing hood is formed from a substantially rigid sheet of plastics material and includes a set of side panels which are connected by an integral hinge to a top panel connected by an integral hinge to a rear panel which, in turn, is connected by an integral hinge to a flange secured to a base control panel mounted within the front compartment of the case. The hood assembly also includes a second mirror and a rear projection viewing screen which is removable for projecting onto a remote viewing screen. The rear projection screen is normally stored within the cover member for the front compartment.
