Identification flasher X-ray film labeling unit

An identification labeling assembly, for association with an x-ray machine, responsive to an input control signal provided in response to an operator input, for providing identifying labeling data for recordal on a sheet of x-ray film enclosed in a film cassette having a corner window hatchway with a sliding hatchcover, said assembly comprising:

• A. a housing incorporating a single cassette insertion slot with hatchcover opening and closing means therein, said housing having otherwise a totally closed outer surface unbroken by card insertion slots,
• B. external data input means, responsive to data input by said operator, for providing a first data input control signal,
• C. computer means, responsive to said first data input control signal and to a second data input control signal from the x-ray machine for providing first and second display signals for displaying data for recordation,
• D. external data display means, responsive to said first and second display signals for displaying said data for recordation, wherein said external data input means, said computer means and said external data display means together form a portable computer unit, mounted on said housing,
• E. means forming a self-illuminated internal display screen defining an object plane positioned inside said housing, substantially isolated from external illumination, and responsive to said first and second display signals from said computer means for displaying said data for recordation on said object plane display screen,
• F. an optical system positioned inside said housing and aligned to provide an image solely of said object plane focussed at an image plane within said cassette-insertion slot, avoiding said need for insertion slots to receive data-bearing cards or labels as objects to be imaged for labeling said film, and
• G. trigger means connected to energize said internal display screen for automatically providing said data for recordation via said optical system to said image plane when said cassette is inserted in the insertion slot and the window hatchway is opened and when said cassette contacts said trigger means,
• whereby the sheet of x-ray film has said data for recordation applied to it photographically without requiring separate typewritten or handwritten data cards or labels.
