<p>Apparatus for projecting slides, comprising at least two lenses; to each of them are ajoined one condenser and one projector lamp, as well as one slide inserted between the condenser and the lens; the projector lamps are adjustable independently from each other. In order to project with an accelerated image projecting rate a plurality of slides one after the other or, partially simultaneously on the same portion of a screen, there is proposed to maintain a plurality of lenses (1a, 1b, 1c, 1d, 1e, 1f) at a small distance from each other by a lens holder (5), the condensers (2) ajoined to the lenses (1a, 1b, 1c, 1d, 1e, 1f) being held in the same order in a condenser holder (6), and the slides (4a, 4b, 4c, 4d, 4e, 4f) ajoined to the lenses (1a, 1b, 1c, 1d, 1e, 1f) being held in the same order on a flat and interchangeable slide holder (7). </p> |
