ABSTRACT:
A training device including a slide projector and a magnetic audio reproducing device is disclosed. The projector is provided with a code reader for reading a code on a film for each image frame. The code indicates the address number of the frame and the information contained in the frame. The training device includes an operating circuit connected with the code reader for addressing the various image frames. A group of switches operated by a student is connected in the operating circuit to provide an answer signal and a frame address number-signal to the operating circuit. A controller circuit is connected with the operating circuit and responsive to a signal from the operating circuit to operate a film drive circuit. The operating circuit controls the film drive circuit through the controller circuitry for selecting and bringing an appropriate subsequent frame of the film to the projection station depending on which of the group of switches is operated by the student.
