    摘要: An object of this invention is to prevent an increase in energy applied to a heating element and prolong the service life of a printhead even when the temperature of the printing element having a negative temperature coefficient rises and the resistance of the heating element decreases upon controlling a switching element for controlling a current flowing through the heating element so as to make energy as constant as possible. For this purpose, a printhead having a plurality of heating elements connected to a common power supply comprises: a switching element which is series-connected to the heating element and controls driving of the heating element at a voltage applied to a control terminal; a constant voltage source using a common power supply as a reference; 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. Then, a current flowing through the heating element is made constant without any influence of the temperature of the heating element.

    摘要: To supply electromotive force to a solid semiconductor element in an ink tank in a non-contact and stable manner. An electromagnetic apparatus (a standstill electromotive force supply unit) is placed at a home position HP. When a carriage is at a standstill at this home position HP, if the electromagnetic apparatus is AC-driven, magnetic properties of both ends (magnetic poles) continue to change mutually and penetrate a solid semiconductor element in the ink tank on the carriage so that a constantly changing magnetic flux is generated. Electromotive force is generated by electromagnetic induction on a coil of the solid semiconductor element. In addition, if the carriage reciprocates during printing operation, the coil L of the solid semiconductor element crosses inside the magnetic flux due to a plurality of permanent magnets (a movement time electromotive force supply unit) arranged on a carrier path (range of movement), and so the electromotive force is generated on the coil by electromagnetic induction. Such electromotive force is converted into energy for activating and operating the solid semiconductor element.

    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.
