Abstract

PURPOSE:To maintain an ink temperature constant in a liquid temperature controller in an ink jet printer by controlling a heater in accordance with the differential voltage between the sum of the output voltages of the environmental temperature detected by a temperature detector and the heater temperature and a reference voltage for providing the prescribed temperature. CONSTITUTION:The temperature of the ink flowed from a head 1 when an environmental temperature Ta is a deg.C is represented by A deg.C. At this time, the detected voltage of the first temperature detector provided in no contact with the head 1 is represented by S1, the detected voltage of the second temperature detector 9 provided at a heater 6 is represented by VS2, and the temperature setting voltage of a controller 5 is represented by Vref. A voltage is applied to the heater 6 to satisfy the condition of the following equations: VS1+VS2 Vref, Vref-(VS1+VS2) 0. When the environmental temperature Ta is raised to b deg.C, the variation becomes DELTATa=(b-a) deg.C. This variation DELTATa is detected by a detector 8, and the voltage corresponding to the DELTATa is raised. Accordingly, the controller 5 lowers the voltage VH of the heater 6 in the amount corresponding to the DELTATa at the output voltage of a detector 9.
