REFERENCE PATTERN FOR ALIGNING INK JET CARTRIDGE

摘要

PURPOSE: To position a precise image by a constitution wherein each of spacings of a plurality of vertical bars horizontally spaced and a plurality of horizontal bars vertically spaced is made to be approximately equal to the width of the bar. CONSTITUTION: A carriage positioning mechanism 110 includes a carriage position motor 112 and the motor 112 has a shaft 114 extending therefrom through which the motor drives a small belt 116. Through the small belt 116, the carriage position motor 112 drives an idler 122 via the shaft 118 thereof. In turn, the idler 122 drives a belt 124 which is secured by a second idler 126. The belt 124 is attached to the carriage 100 and adapted to slide therethrough. The position of the carriage assembly in the scan axis is determined precisely by the use of a code strip 120.
