e/Slide Cube projector

Information
has gloss	eng: A slide cube projector is a type of slide projector that was created by Bell & Howell and was sold up through the 1980s. The system gets its name from the plastic cubes that slides are stored in. The cubes are about 5.5 cm in each dimension (a bit larger than a slide), and hold 36-44 slides depending on the mount thickness. Unlike the trays used in carousel projectors, the slides in a cube are not separated from each other; they are simply stacked one on top of the other. The slide advance mechanism depends on a slide dropping from the loaded cube into a slide-size hole in a circular plate. The plate is thinner than a slide and so should grab only a single slide and move it forward, first to a preview section, then to the projection position, then to a holding position from which it can be returned to allow for a single slide's worth of backup, and then finally to a position in which it drops into a stack that can be pushed back up into the cube after projection is completed.
