    Abstract: An ink jet head circuit board is provided which has heaters to generate thermal energy for ink ejection as they are energized. This circuit board reduces areas of the heaters to achieve higher printing resolution and image quality. This board also prevents a degradation of thermal energy efficiency and reduces power consumption. The protective insulation layer for the electrode wire layer (103) is formed of two layers (108a,108b) and one of the two layers, (108a), is removed from above the heater (102) to improve the heat energy efficiency. The resistor layer (107) is deposited over the electrode wire layer (103). The patterning for removing the protective insulation layer (108a) is done in a wider range than a gap of the electrode wire layer (103), the gap being used to form the heater. Further, by forming the electrode wires in two layers, a possible reduction in an effective bubble generation area of the heater (102) can be prevented.

    Abstract: The present inventions allow the detection of ink in the printing head by significantly simplified their configurations and on which various printing systems can be widely applied. There are a heater (101) for supplying an energy to ejecting ink, a driver (102) for driving heater (101), and a detection electrode (118) capable of detecting a voltage variation between the heater (101) and the driver (102) to be occurred depending on the driving of the heater (101). Furthermore, an insulating film (410) that covers the surface of the detection electrode (118) prevents a chemical or physical change from the detection electrode (118). Furthermore, a reference element group or a reference unit that produces a signal as a reference of the detection signal avoids the influence of noise. Furthermore, an energy-generating element (101) and another signal source (101) improve the accuracy of ink-detection. A drive pulse which is insufficient to ejecting ink may be supplied to the heater (101) to improve the accuracy of ink-detection.

    Abstract: A stable operation is realized without any malfunction of a driver even under a voltage condition that a supplied voltage is 3.3 V or lower. For this purpose, in an ink-jet printhead having an ink orifice for discharging ink, a plurality of heat generation elements for generating heat energy used to discharge ink, and an ink channel which incorporates the heat generation elements and communicates with the ink orifice, a driver for driving the heat generation elements, and a logic circuit for controlling the driver are formed on a single board. The gate oxide film thickness of an enhancement NMOS transistor which forms the driver is larger than that of an enhancement NMOS transistor which forms the logic circuit.
