<p>Projector intended to show slides on a screen. Series of slides are hingedly interconnected. A band-like series of slides is arranged between a light source and a lens to be displaced along the series of slides to project a slide one after the other on the screen. If the slides of a series have been shown, the chain is displaced from one position in order to bring the next series of slides instead of the preceding one between the light source and the lens. The present invention includes a particularly useful solution to form, from a plurality of series of slides, chains comprised of a plurality of hingedly interconnected series.</p> |
