Abstract
In a mixing projector, a guide element for the slide magazine extends transversely with respect to the optical axes of the objective lens systems of the optical assembly. Disposed between the two projector units for projecting the respective slides is a main slider member which is displaceable parallel to the optical axes of the optical assembly, for transportation of slides between the magazine and a slide turning mechanism which turns the respective slides through 90.degree.. Transverse slider members then provide for transportation of the turned slides into and out of the positions thereof for projection through the objective lenses of the optical assembly.
Claims6
A mixing projector comprising:
- first and second image projector means forming a projection assembly and each comprising an objective lens, a slide projection position and lighting system;
- a guide means for mounting a common slide magazine for accommodating a plurality of slides, said guide means extending transversely with respect to the optical axes of the first and second projector means;
- a main slider member arranged between the first and second projector means , said main slider member displaceable in parallel relationship to said optical axes, for taking a respective slider from said magazine for projection thereof and for introducing a respective slide into the magazine after projection thereof;
- a slide turning means disposed in the path of displacement of the main slider member, said slide turning means being rotatable about an axis at least substantially perpendicular to the path of displacement of said main slider member, for turning the slides introduced into the turning means through 90.degree.;
- and a respective transverse slider member operatively associated with each said slide projection position for changing a respective slide between the respective slide projection position and said turning means.
A mixing projector comprising:
- first and second projector units disposed in side-by-side and spaced relationship and each comprising an objective lens means and a lighting system, for projecting the images of respective slides;
- means for displaceably mounting a magazine for accommodating a plurality of slides wherein at least a portion of said mounting means extends transversely with respect to the optical axes of said projector units;
- slide turning means operatively disposed between said projector units and said magazine mounting means and actuable to return a slide carried by said slide turning means between a first position of being disposed parallel to said optical axes and a second position of being perpendicular to said optical axes;
- first transfer means disposed between said first and second projector units and displaceable parallel to said optical axes, operable for transferring a slide between said magazine and said turning means when said turning means is in a first position;
- and second transfer means for displacing a slide between said turning means when said turning means is in a second position and a position on the optical axis of a respective said projector unit for projection thereby.
