摘要： This invention relates to a printhead substrate capable of suppressing an increase in wiring width and an increase in the size of a substrate formed by a film forming process while increasing the number of simultaneously driven printing elements in order to improve the printing performance, a printhead using the substrate, and a printing apparatus using the printhead. The wiring lines of the substrate are formed into a common wiring line, and energy applied to a heating resistance element is prevented from deviating from a stable ink discharge range owing to the difference in the number of simultaneously driven heating resistance elements. For this purpose, a driving element is greatly downsized in comparison with a conventional one, and the operation region of a MOS transistor is shifted from the non-saturation region to the saturation region.

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.

摘要： An ink jet head circuit board is provided which has heaters to generate thermal energy for ejecting ink as they are energized. This circuit board is so constructed as to reduce wire resistances for the heaters while at the same time preventing an increase in the size of the board and realizing a high-density integration of the heaters required for high resolution printing. This construction is made possible by forming electrode wires of first and second electrode wire layers to reduce an area that the wire patterns for the heater occupy on the circuit board. In reducing the effective thickness of protective insulation layer formed on the heater to prevent a possible degradation of thermal efficiency, one of the protective insulation layers over the electrode wires is removed from the heater, depending on the thickness of the electrode wires.
