Abstract

The system provides great physical flexibility and convenience for the televising of documents and diagrams for lecture purposes. The design allows the camera a smooth 180 deg. field of movement without any excessive equipment weight penalty. The design requires the use of a projection mirror giving 0 deg. to 180 deg. of rotation and accommodate '8' or super '8' cine film, the camera being mounted on a three pivot arrangement, the articulating joints of which have packing pieces of plastic or metal provided with braking adjustment. Provision is made for an auxiliary camera with or without positional adjustment.
