Title:
LIQUID DISCHARGE HEAD AND LIQUID DISCHARGE DEVICE
Document Type and Number:
Japanese Patent JP2018161787
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid discharge head and a liquid discharge device which accurately detect temperature and can appropriately control operation.SOLUTION: A liquid discharge head includes: a liquid discharge part discharging liquid; a first temperature sensor detecting temperature of a drive circuit driving the liquid discharge part or of a circuit board the drive circuit is provided with; and a second temperature sensor detecting temperature of the liquid discharge part or temperature of liquid in a prescribed flow channel communicating with the liquid discharge part. When detection value detected by the first temperature sensor is outside a prescribed allowable range, printing operation is stopped; when detection value detected by the first temperature sensor is within the prescribed allowable range, drive voltage to be given to the drive circuit according to the detection value detected by the second temperature sensor is controlled to cause printing.SELECTED DRAWING: Figure 7
