摘要： An increase in energy applied to a heating element can be prevented and the service life of a printhead can be prolonged even when the temperature of the printing element having a negative temperature coefficient rises and the resistance of the heating element decreases. A printhead having heating elements connected to a common power supply comprises a switching element series-connected to and controlling driving of the heating element at a voltage applied to a control terminal; a constant voltage source; a wiring resistance generated at a connection wiring line serial-connected to the heating element; and a voltage control circuit which controls to make the potential difference between both ends of the wiring resistance equal to the voltage of the constant voltage source when driving the heating element. A current flowing through the heating element is made constant without any influence of the temperature.

摘要： A recording head comprises a plurality of recording elements for performing recording; a driving circuit for driving the plurality of recording elements; and a predetermined voltage generating circuit for generating a predetermined voltage to be applied to the plurality of recording elements from voltage supplied from outside. With the head thus structured, a desired voltage is generated in the interior of the head by use of the predetermined voltage generating circuit for performing recording, thus making it possible to prevent the voltage drop which may take place if the voltage is supplied from outside through a cable, as well as to prevent the durability of the heat generating elements from being damaged due to noises. It also becomes possible to set the voltage to be applied to the recording elements at an optimal value corresponding to the discharge voltage, hence stabilizing ink discharges efficiently.
