ABSTRACT:
Disclosed is a drive mechanism for a slide projector adapted for accepting a circular slide magazine of the type including an approximately h-shaped configuration wall having a pair of forked inner and outer wall parts in coaxial spaced relationship located near the axial end of the housing which abuts the projector, the outer wall part having on its side facing the inner wall part a plurality of recesses corresponding in number to the slide compartments. The drive mechanisms for selectively rotating the slide magazine comprises a drive member mounted for rotation on the projector housing at a location adjacent the h-shaped wall configuration of a mounted slide magazine, and at least one drive pin mounted excentrically on the drive member substantially parallel to the axis of rotation of the drive member, for projecting into the space between the inner and outer wall parts of the h-shaped configuration.
