Abstract
A slide projector which is suitable for both wall projection and ground-glass plate projection has a displacement means carrying a deflection mirror system and a ground-glass plate. The displacement means is movable between a collapsed condition in which the displacement means with mirror system and ground-glass plate is in a compact configuration in a housing compartment beneath the projector, for wall projection purposes, and a deployed condition for ground-glass plate projection purposes, in which the displacement means is moved out of the housing compartment into a position in which the mirror system and the ground-glass plate are in front of the lens system of the projector.
