Optical printer head, light-amount correction method for optical printer head and optical printer |
摘要 |
An optical printer head capable of increasing a level of a light amount for exposure emitted from luminous dot trains in view of an end cool phenomenon of filamentary cathodes and reducing loss of exposure energy. A light source includes luminous dot trains each constituted by a plurality of luminous dots each including an anode arranged on an anode substrate and a phosphor layer deposited on the anode, as well as filamentary cathodes arranged above the luminous dot trains so as to extend along the trains. A memory device is arranged so as to store therein correction information for ensuring uniform luminescence of the luminous dots. Light-amount correction is carried out on the luminous dots other than those positioned in proximity to each of both ends of the luminous dot trains excluded from light-amount correction, to thereby obtain correction information on the former luminous dots, which is then stored in the memory device. The correction information permits a light amount of each luminous dot to be substantially distributed around a minimum value of a light amount of all luminous dots stored in the memory device.
