Mechanism for transporting a slide from a long magazine into the optical channel of a slide projector

摘要

Apparatus is disclosed for viewing photographic slides carried in a long magazine by a slide projector which is configured to accept only a circular slide magazine or carrousel. This invention provides a simple and efficient mechanism for using long magazines with a circular magazine projector without the need of first transferring by hand all of the slides from the long magazine into a circular magazine. An attachment adapted to be fastened to the projector housing has a covered channel for accepting and advancing a long magazine inserted therein. Adjacent the long magazine within the attachment is an intermediate storage tray which contains slide compartments and which is moved synchronously with the long magazine. Slanting guide rails extend from the long magazine to the intermediate storage tray, and these rails individually transfer the slides from the long magazine into the storage tray as the long magazine is advanced. Each slide is individually placed in a position over a chute in the base of the attachment through which the slide drops into the optical channel of the projector. Once the slide has been returned to the storage tray from the optical channel of the projector, the slide is returned by the guide rails from the storage tray to the long magazine.
