ABSTRACT:
An X-ray apparatus includes a spot filmer for feeding sheets of unexposed film one at a time into a vacuum evacuable assembly for exposure, and for returning exposed film sheets to an exposed film magazine. The spot filmer has a housing defining a light tight enclosure. The film magazines are insertable through a door into the housing and into a film feed mechanism. The film feed mechanism unlatches, opens and positions the magazines; feeds a sheet of unexposed film into the vacuum evacuable assembly; releases the film sheet so the assembly can position the film sheet for exposure; and closes the film magazines. An orthogonal drive system positions the vacuum evacuable assembly to expose selected film sheet portions, and returns the assembly to a retracted position. The film feed mechanism opens the magazines; feeds the exposed film sheet into the exposed film magazine; and closes the magazines. The structures of these several mechanisms are described.
