ABSTRACT:
A two-part circular magazine having an inner rotor with slide storing compartments and an outer stator enclosing the rotor is arranged to mount and operate in the magazine guide of a linear magazine slide projector. The stator has a tangential groove opening to the rotor in the region of a radial slot for transverse passage of a slide from the magazine, and the groove has side walls that fit opposite sides of a slide lifting ramp in the bottom of the magazine guide. The rotor exterior is positioned directly over the top of the lifting ramp when the magazine is mounted in the projector, and the stator has an inclined surface ascending from below the top of the lifting ramp upward to the level of the interior of the rotor in the region of the slot. The stator also has abutment surfaces that engage parts of the magazine guide to position and maintain the magazine accurately in place.
