Title:
LIGHT SOURCE FOR FLUORESCENT PRINTER
Document Type and Number:
Japanese Patent JPH0569588
Kind Code:
A
Abstract:

PURPOSE: To obtain a light source for fluorescent printer not being adversely affected by an electronic charge and an electric field formed by an opposed control electrode but improved in electrode pattern accuracy.

CONSTITUTION: On a glass substrate 1, anodes 7 are arranged in a main scanning direction to form an anode train. Two trains of the anodes are juxtaposed in a sub-scanning direction. The two anode trains are staggered. Between the two anode trains, anode conductors 2, 2 of the adjacent anodes 7, 7 in the staggered arrangements are connected with each other through a wiring conductor 3a. The anode trains are respectively surrounded by control electrodes 4a, 4b, which are electrically independent of each other. The control electrodes 4a, 4b are opposed to each other at an intermediate position between the two anode trains. The absence of an insulating layer prevents a light source from being adversely affected by an electronic charge. The anode train is hardly affected by the control electrode of the opposed anode train.
