Abstract

1. Fade-in slide projector consisting of two complete projector systems arranged to one side of the joint strip magazine in which the slides are contained in consecutive projection sequence and to which they are returned in the original sequence after projection, characterised in that the two projectors (I and II) are arranged in a fixed position and staggered in axial direction in such a way that the slide change pick-up passage between the magazine (31) and the outer projector (II) is always left free by the projector (I) which is closer to the magazine, and in that an additional drive (35-39) for the strip magazine (31) or its strip magazine guide (30) is superimposed on the indexing mechanism (41) such that, during the changing of consecutive slides, the strip magazine (31) can be moved backwards and forwards by the distance between the picture change planes (1', 2') of the two projectors (I, II).
