Multidirection, multi-slide projector - uses flat sheets of slides with movable carriages to place slides in optical light path

摘要

The projector has one or several carriages which can be displaced in two opposite directions along the same longitudinal axis. Each carriage has a movable element which permit rows of slide frames placed on the upper parts of the carriages to be displaced in opposite directions and perpendicular to the carriages movement. The different movements of the carriage and movable element enables each slide to be placed opposite and in the ray emitted by the optical compartment (17) under the carriage. A mirror inclined at 45 deg. and placed at the end of the objective (19) pivots on its axis and sends projected images in different directions.
