Abstract
PURPOSE: To provide a uniform level signal for the video output terminal by gradually increasing the width of a light radiating slit from the center to both ends of a fluorescent lamp tube.
CONSTITUTION: The width of a light radiating slit 10 of a fluorescent lamp 1 use for a pattern input device having a licenser 4 is increased gradually from the center to both ends of the fluorescent lamp tube, thus applying a uniform and shadeless video signal to the output terminal of a video circuit.
