An apparatus for the continuous and automatic projection of slides, characterized by one or several luminous focuses, whose rays directed towards a subsequent screen, are reflected in the form of beams of parallel rays towards the projection windows. In this way the slides placed in front of the condensing lenses are constantly illuminated, but the light rays are intercepted in front of the slides, except of course those corresponding to the slide that is being projected.
