ABSTRACT:
A hand-held projector for projecting from a transparency on a film strip and image onto any desired surface. The film strip with a series of transparencies is guided in a casing which has a front peripheral wall portion carrying an objective behind which is situated a light source with the film being guided between the light source and objective. A manually operable member is accessible for feeding the film strip frame by frame along the guide in the casing so that successive transparencies will be projected. Batteries from which energy is derived for the light source are situated in the casing on opposite sides of the light source so that a balanced compact arrangement is achieved.
