摘要
The subject matter of the invention is constituted by a projection apparatus for the projection of transparencies on to a screen. The transparencies are articulated together. One at a time the rows of transparencies are located between a light source and a lens, same being moved along the row of transparencies in order to project the transparencies in order on the screen. When the transparencies of one row have been projected, the chain is moved through one step in order to place the next row of transparencies in place of the former one in between the light source and the lens. The invention furthermore relates to a particularly convenient design by which a number of transparency rows may be chained together with articulating joints therebetween.
