DEVELOPMENT DEVICE

摘要

A device for high speed development of a latent image on a strip of heat developable film moved by a drive means along a path in the device. The device includes a heated rotatable drum about which the film is tensioned and which affords conduction of a uniform predetermined quantity of heat to all areas of the film to effect even development thereof. The device includes means to thoroughly clean the surface of the film and of the drum prior to contact therebetween, and provides a cooling means to terminate development of the film after the film is separated from the drum.
