ABSTRACT:
A circular magazine for a slide projector which is adapted to be molded in one piece. The magazine has a circular bottom wall (5) with an internal hub extending vertically therefrom defining an inside boundary wall (4). A plurality of slide compartment walls (2a) extend vertically from the bottom wall. At the upper right hand corner of each compartment wall a portion of the wall is elevated or expanded (6). Slides are held in position by the resilient pressure of the expanded portions (6) of corresponding compartment walls against the upper right hand corners of the slides and the lower left hand corners of the slides are seated against the L-shaped cross section of the bottom wall (5) and boundary wall (4). The legs of the bottom wall (5) and boundary wall (4) are foreshortened to lengths less than the linear dimensions of a slide so that a gripping device can extract the slides vertically to a projector or horizontally to the right into a projector.
