Abstract
A slide projector that is portable, easy to use and suitable for use by an individual, or individuals in the home. The slide projector comprises means in which to project an image perpendicularly from a slide onto a projection surface. In use, the projected image of the slide lies in a substantially planar surface. The slide is located in a rotating carousel which can be automatically, or manually, rotated, thus providing accurate simulation of the orientation of stars and other celestial bodies at a specific date and time.

A slide projector comprising projection means for directly projecting an image from a slide perpendicularly onto a projection surface, the projection means being such that the projected image of the slide lies, in use, in a substantially planar projection surface, the projection means comprising:
- a light source;
- at least two vertically juxtaposed slides parallel to each other;
- rotation means to rotate at least one of the slides;
- and
- means to provide and air flow to thereby provide a negative pressure below said slides to retain the slides in their respective positions.
A slide projector comprising projection means for directly projecting an image from a slide perpendicularly onto a projection surface, the projection means being such that the projected image of the slide lies, in use, in a substantially planar projection surface, the projection means comprising:
- a light source;
- at least two vertically juxtaposed slides parallel to each other;
- rotation means to rotate at least one of the slides, the rotation means is in the form of a rotatable carousel;
- and
- a projecting lens movable between a first position, directly above the at least two slides, and a second position away from the first position, thereby to allow easy access to the slides.
