に至ることがあつた。 Conventionally, a liquid jet recording device has been one of the excellent recording methods in terms of non-impact recording, low noise, high density, high speed recording, and easy colorization. However, in liquid jet recording devices, changes in the outside air temperature affect the temperature of the liquid used for recording, and this change in temperature of the liquid sometimes has an adverse effect on recording. As shown in FIG. 1, the viscosity of the liquid used in the liquid jet recording method increases significantly as the temperature decreases. As a result, the diameter of droplets formed by being ejected from the orifice may become smaller, satellites may be formed, and the ejected liquid may cause splash. Furthermore, the orifice sometimes became clogged with the thickened liquid.

設定しておく。 FIG. 3 is a block diagram of a control circuit that uses a thermistor as the temperature detector 208 of the liquid jet recording head shown in FIG. 2 and controls the heater 206 according to temperature changes. In the figure, 301 and 302 are thermistors for detecting external temperature, and their resistance values change depending on the temperature as shown in FIG. In other words, the resistance value increases as the temperature decreases. 307
is a pulse generator that generates pulses with a constant period; 3
06, when the pulse generated from the pulse generator 307 is applied, the thermistor 301, the resistor 303,
This is a one-shot circuit that outputs a pulse with a constant value set by the value of the capacitor 305, and the pulse width output from this one-shot circuit is T.
Then, T is determined by T=(R Th +R)·C·k. Here, R Th is the resistance value of the thermistor 301,
R is the resistance value of the resistor 303, C is the capacitor 305
The capacity, k, is a constant. 308 is a comparator, and the values of the thermistor 302 and resistors 304a to 304c are set so that the output of the comparator 308 changes from a low level to a high level when the temperature reaches a certain temperature at which liquid such as ink must be heated.

A low voltage V L with an energy level insufficient to form flying droplets is constantly applied to the collector side of the droplet. 312 is a diode connected to the emitter side of the transistor 310, and 311 is a transistor that turns on when a printing pulse is applied to the base from a control circuit (not shown), so that a high voltage VH capable of forming flying droplets is constantly applied. is being applied.

resistance increases, and the potential on the minus input side of the comparator 308 becomes lower than the potential on the plus input side. Therefore, the output of the comparator 308 is always at a high level below that temperature, and is provided as one input to the AND gate 309.

VHがヒーターに印加され、液体噴射が行われる。 On the other hand, when a pulse generated by the pulse generator 307 with a certain constant period is applied to the one shot circuit 306, a pulse with a certain constant width is outputted from the one shot circuit 306 depending on the values of the thermistor 301, resistor 303, and capacitor 305. The pulse width of the output pulse of this one-shot circuit 306 is
It changes depending on the change in the resistance value of the thermistor 301 due to temperature change. Therefore, as the temperature decreases, the resistance value of the thermistor 301 increases, so the pulse width of the output pulse from the one-shot circuit 306 also increases, and this is given as the other input to the AND gate 309. Yotsute and Gate 30
9 outputs a pulse that is longer at lower temperatures depending on the temperature and is applied to the transistor 310 only when the temperature of the liquid drops below a certain level at which it is necessary to heat the liquid. Therefore, during that pulse width, transistor 310 is turned on and a low voltage V L of an energy level that cannot form flying droplets is applied to heater 313 to heat the liquid. When the liquid reaches a temperature sufficient for printing, a printing pulse is applied to transistor 311, which turns on and generates a high voltage that can form flying droplets.
V H is applied to the heater and liquid jetting occurs.
よつてある温度以下では、液体はヒーター３１
３により温度に応じた時間だけ加温されるため
に、液体温度は常に一定となる。 Below a certain temperature, the liquid passes through the heater 31.
3, the liquid temperature is always constant because it is heated for a period of time depending on the temperature.

A large number of heaters can be controlled by one set of control circuits.
