Document Type and Number:
Japanese Patent JP2608547
Kind Code:
B2
Abstract:
A write device for an optical printer capable of determining intervals between luminous dots and inclination and dimensions of the luminous dots with high precision to improve printing quality of a printer. The write head includes luminous dots defined on each of a plurality rows of anodes. The luminous dots arranged obliquely across the row of the anodes are driven to emit lights which are uninterruptedly linearly irradiated together in a direction perpendicular to a direction of movement of a record medium on a surface of a record medium. The write head also includes an electro-optical shutter which is arranged in front of the obliquely arranged luminous dots and adapted to be varied in optical characteristics in synchronism with an emission driving signal supplied to the anodes to selectively shield or transmit light emitted from each of the luminous dots.
