Title:
SYSTEM FOR SUPPLYING AND WINDING MOVIE PROJECTOR FILM
Document Type and Number:
Japanese Patent JPS5242120
Kind Code:
A
Abstract:
An improved film supply and take-up transport for use with a motion picture projector. At least two horizontal film platters are connected through bearing plates to a single vertical drive shaft. A circular film winding core is selectively positioned concentric with the shaft on one platter. The core engages a mechanism for locking the platter through the bearing plate to the drive shaft for operating the platter in a take-up mode. A motor is controlled to rotate the drive shaft for winding the film onto the core at the same rate that the film is advanced through the projector. Film is supplied to the projector from the center of a film coil on another platter which is coupled through its bearing plate to the drive shaft. A brake is intermittently operated to slow the supply platter below the speed of the drive shaft to maintain a desired film supply rate.
