摘要

The projection appts (1) for slides has a housing (100) and screen (120). Several lenses are arranged on a carrier to which condensers are assigned in a similar arrangement on another carrier. Projection lamps are also simularly arranged and assigned on a further carrier. A slide carrier plate (4) is slidable between the condensers and lenses such that a slide is assigned to each lens in the same order. The projection lamps are independently controllable. The lenses, condensers and lamps are so fixed in their carriers that their optical axes cut each other at the screen. Mirrors (15) are assigned to the lamps. The control pref. has a c.p.u. which is freely programmable. USE/ADVANTAGE - Handy, as small as possible, low servicing requirement, robust. Automatically shows certain number of selected slides. Program control also selectable.
