PROBLEM TO BE SOLVED: To provide a liquid injection device that can suppress a temperature of a nozzle in an injection part from excessively rising.SOLUTION: A liquid injection device 11 comprises: an injection part 14 that sprays ink to a continuous paper P; a heating part 15 that heats a liquid injection region RIL, a region where the injection part 14 can spray the ink to the continuous paper P; an IR sensor 29 that detects a temperature of the liquid injection region RIL; a nozzle plate thermistor 24 that detects a temperature of a surface opposing to the continuous paper P in the injection part 14; and a control part 30 that controls the heating part 15 on the basis of a first detection temperature detected by the IR sensor 29 and a second detection temperature of the nozzle plate thermistor 24.SELECTED DRAWING: Figure 1 |
