LIQUID JET RECORDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent the density irregularity caused by the joint of a heater board. SOLUTION: A full-line liquid jet recording head 101a is formed by joining relatively short boards 11a-11k to produce a long heater board and combining an integrally molded grooved top board with the heater board. For example, in a color printing liquid jet recording apparatus leaded with force liquid jet recording heads, the strip like part 4a of one end of the base plate 4 of the liquid jet recording head 101a is curt to form a second liquid jet recording head and the strip like part 4b of the other end of the base plate 4 of the liquid jet recording head 101a is cut to form a third liquid jet recording head and these liquid jet recording heads are held on a head holder to be arranged so that the joints of the heater boards are alternated with each other.
