Universal projector for microfilm and large format masters - has adjustable mirror and selective objective projecting images onto common display

摘要

The universal projector may be used for projecting microfilm as well as large format masters onto a copy sheet. It has a variable optical system (40,3) to project any selected magnification, or reduction to produce microfilm or large readable copies. The copies are arranged in a cassette loading device (9) for use outside a darkroom. The projection is controlled by a universally adjustable mirror system. It enables the equipment to be used as a microfilm reader as well as to take copies.
