A motion picture projector for multiple sound track films comprises a plurality of selectively operable transducers so disposed around a drum that each co-operates with a respective sound track of the film when the projector is in operation. As described, the apparatus (Fig. 1) records and/or reproduces sound and control signals on one 16 mm. sound film of a rotatable magazine T, the films either being wound on to a single take-up spool B or a corresponding spool on a similar rotatable magazine, or the films may be contained in single- or double-spool cassettes. The control signals may be used to operate associated apparatus such as kaleidoscopes, dispensing or advertising machines or to control operation of a device e.g. toy being displayed. The projector may constitute a language teaching machine in which the student records his voice on one sound track while an audio-visual lesson is in progress, later to play back his attempt, possibly simultaneously with the visual information. The multiple sound tracks may contain information in different languages or three-channel stereophonic sound. The projector may be coin, token or pushbutton operated. Construction.-A projector employing one optical and two magnetic transducers is described although all three transducers may be of one type. As shown the film 1 is pressed against a drum 6 by rollers 5 on an arm 4 which also carries a prism 7 and lens 8 for projection of the film on to a screen 5, and a lamp 9 and associated lens for the optical sound track. Alternatively, the lamp 9 may be mounted on the support 3 and the sound group 2 mounted on the arm 4. A magnetic head 23 (Fig. 3) is carried by a bracket 32 pivoted about an axis 35 and axially movable along guide pins (36, 38, Fig. 2, not shown) by adjuster nut 39. The bracket 32 is biased counterclockwise by spring 41 so that the head 23 bears resiliently against the film 1, the spring tension being adjusted by nut 26. A second magnetic head (24) is mounted on the support so as to be laterally adjustable by a nut (51) and to bear resiliently against the film by springs (49), the head (24) being circumferentially displaced from the first head 23.
