Magazine for slides for the simultaneous projection of pictures and reproduction of sound

Projection and sound reproduction apparatus, adapted to accommodate a self-contained, portable compact composite longitudinal magazine carrier having a picture slide magazine operatively receiving a plurality of diapositives and an endless sound tape mounted for movement along an endless path and carrying a plurality of endless sound tracks transversely side by side thereon with each sound track corresponding to a diapositives so that upon projection of a diapositive the associated sound track is simultaneously reproduced which comprises

• means for intermittent stepwise advancement of such a magazine carrier along a longitudinal advancement path to pass a projection station,
• means at the projection station adjacent to the path for selective movement of a corresponding diapositive from the magazine of the magazine carrier to a projection position at a corresponding intermittent step of such stepwise advancement for projecting the diapositive for viewing,
• an accessory assembly including cooperating drive means for driving the endless tape in any position of advancement of the magazine carrier and a sound head for concordant reproduction of associated sound from the endless tape, and
• means to displace the sound head transversely with respect to the path and in turn with respect to the plurality of endless sound tracks in dependence upon the position of advancement of the magazine carrier along the path, for corresponding selective simultaneous operative engagement of the drive means and the sound head with the endless sound tape for driving the endless tape and for concordant reproduction of associated sound from a corresponding sound track at the point of transverse displacement of the sound head when a diapositive is in the projection position at a corresponding intermittent step of the stepwise advancement.

Projection and sound reproduction apparatus and a magazine carrier therefor, which comprises in combination

• a self-contained, portable compact composite longitudinal magazine carrier for projection of diapositives with simultaneous concordant reproduction of associated sound upon intermittent stepwise advancement of the magazine carrier along a longitudinal path in the projection and sound reproduction apparatus,
• said magazine carrier including a longitudinal picture slide magazine portion provided with means defining a plurality of compartments in tandem longitudinally for operatively receiving diapositives respectively in generally parallel arrangement in a stored position therein for individual movement from such stored position to a projection position in accordance with such stepwise advancement,
• said magazine carrier further including a longitudinal sound tape container portion provided with an endless sound carrier means formed as a separate longitudinally extending endless tape and guided for movement along an endless path for carrying a plurality of endless sound tracks with each sound track corresponding to a diapositive so that upon projection of the respective diapositives the associated sound of a corresponding sound track is simultaneously reproduced,
• said endless tape being operatively disposed for corresponding selective simultaneous operative engagement with a sound head of the sound reproduction apparatus and associated drive means to drive the endless tape for sound reproduction via such sound head during such movement along said endless path when a dispositive is in projection position at a corresponding intermittent step of such stepwise advancement,
• said magazine portion and tape container portion being provided as a portable compact composite unit for common stepwise advancement along the longitudinal path,
• means for intermittent stepwise advancement of the magazine carrier along the longitudinal advancement path to pass a projection station in the projection and sound reproduction apparatus,
• means at the projection station adjacent to the path for selective movement of a corresponding diapositive from the magazine portion of the magazine carrier to the projection position at a corresponding intermediate step of the stepwise advancement for projecting the diapositive for viewing,
• drive means for driving the endless tape in any position of advancement of the magazine carrier,
• a sound head for concordant reproduction of associated sound from the endless tape, and
• means to displace the sound head transversely with respect to the plurality of endless sound tracks in dependence upon the position of advancement of the magazine carrier along the path,
• said drive means and sound head being operatively arranged with respect to the endless tape for corresponding selective simultaneous operative engagement of the drive means and the sound head with the endless sound tape for driving the endless tape and for concordant reproduction of associated sound from a corresponding sound track at the point of transverse displacement of the sound head when a diapositive is in the projection position at a corresponding intermittent step of the stepwise advancement.
