Document Type and Number:
Japanese Patent JP7047947
Kind Code:
B2
Abstract:
To solve the problem that when a circulation flow path is arranged for every two nozzle rows, a circulation port is required to be provided for each circulation flow path, which makes a structure complicated.SOLUTION: The liquid discharge head has: two nozzle rows 4A and 4B having a plurality of nozzles 4 for discharging liquid arrayed; a plurality of individual liquid chambers 6 communicating with respective nozzles 4 of the nozzle rows 4A and 4B; and two circulation flow paths 41A and 41B corresponding to the nozzle rows 4A, 4B, and communicating with the plurality of individual liquid chambers 6. The two circulation flow paths 41A and 41B communicate with each other through bridging flow paths 44 arranged in a direction crossing a nozzle arraying direction. The bridging flow paths 44 and the circulation flow paths 41A and 41B are arranged at different positions in a thickness direction of flow path plates 2 that form the bridging flow paths 44 and the circulation flow paths 41A and 41B.SELECTED DRAWING: Figure 7
