Abstract

Electrically coded data can be viewed by the use of a magnetic powder, on which a luminescent dye has been sorbed, and ultraviolet light. An apparatus for use with such a magneto luminescent toner is shown. Electrical input signals from an electronic character generating control device 11 are fed to a seven channel head 12 which selectively pulses seven locations across belt 13 to record a magnetic pattern in a seven by seven matrix form.

Magneto-Luminescent Device

Electrically coded data can be viewed by the use of a magnetic powder, on which a luminescent dye has been sorbed, and ultraviolet light. An apparatus for use with such a magneto luminescent toner is shown. Electrical input signals from an electronic character generating control device 11 are fed to a seven channel head 12 which selectively pulses seven locations across belt 13 to record a magnetic pattern in a seven by seven matrix form.

The belt 13 revolves past a belt 14 on which is evenly spread a magneto luminescent toner 15. The toner 15 adheres to the magnetized areas of the belt 13 and is subjected to ultraviolet light from lamp 16 as belt 13 continues to revolve. The toner image is viewed or photographed at aperture 17 and belt 13 is revolved past belt cleaner 18 and erase transducer 19 to remove, respectively, the toner and magnetic image. The recordation of additional data on belt 13 can be accomplished at the same time a record is being viewed or photographed.
