The projector makes use of double partitions (7, 8) and a false floor (9), with a translucent screen inserted between the two partitions to receive an image without loss of clarity at the edges. The screen is adjusted to different film formats by lowering a black cloth in front of it. It can be use for the projecting of 35mm, 70 mm films or other systems. The screen can be used for all types of transparency projection, including monovision, polyvision and multivision. In a variant, instead of having double partitions at the edges the screen can be fitted into a wall recess
