Display System

This display system utilizes a single electronic flash tube for illumination of a plurality of character positions.

Drum 1 driven by motor 2 has a plurality of bands 3, each containing one character set 4. Sets 4 are arranged in staggered fashion so that only one character is in alignment with viewing window 5 at any given time. Transducer 6 reads synchronizing track 7 on drum 1 to identify the characters as they pass before window 5.

The output of transducer 6 is connected to control unit 8 where it is compared with display data input 9. When unit 8 determines that the desired character is in alignment, a trigger pulse is sent to flash tube 10.

An alternative arrangement for generating the trigger pulse to flash tube 10 utilizes devices, not shown, for recording data bits on track 7 only in the position corresponding to characters to be displayed. The output from transducer 6, suitably amplified, is then used to directly trigger flash tube 10.

The resulting light from tube 10 is collimated by lens system 11 and directed into drum 1. Behind each set is a mirror or prism 12 which reflects the light from tube 10 toward aperture 5 making the character visible to the viewer.
