Projector for simulating moving image pattern - uses single image projection system contg. moving member for holding plane of projection system in object plane of projection objective

摘要

The holding system (16) is moved in a specified first direction in the object plane. A moving system including a worm drive (58, 60) and an electric motor (62) moves the holding system (16) in a second direction lying in the object plane. Another drive with a worm-wheel (36), a worm (38) and an electric motor (40) rotates the holding system about an axis vertical to the object plane. The system for moving the holding system in a specified first direction in the object plane, includes a worm drive (48, 50) and an electric motor (52). The adjusting systems for the holding frame (30) are controlled slip free manually and/or by a programme controlled unit. USE/ADVANTAGE - E.g. for medical examination. Projector is efficient, simple in construction, easy to use and has greater matching ability, compared to known light, film and video projectors.
