ABSTRACT:
A portable foldable overhead projector includes a housing having a front opening communicating with an interior cavity, and a bottom aperture communicating with the cavity and closable by a pair of pivoting doors which, when open, support the housing on support legs and accommodate movement of a mirror inside the housing between stowed and use positions. In the use position the mirror reflects light from a source through a transmitting stage in the top wall of the housing which forms a pivoting door to provide further access to the cavity. A mast pivots along the outside of the housing and carries a foldable projection head assembly on a rack and pinion mechanism. When the mast is lowered the rack and pinion can be operated to move the folded projection head assembly through the front opening into the cavity for storage.
