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 fuse element can be reliably blown and data that corresponds to whether or not the fuse element has been blown can be stored with high reliability. A resistor element is provided in a circuit through which an electric current flows to blow the fuse element in the ink jet printing head. The resistor element adjusts the electric current so that, in the process of blowing the fuse element, the current continues to flow for a predetermined duration even after a maximum current has passed through the fuse element. The predetermined duration is longer than a period from a time point when the electric current rises to a time point when the electric current reaches the maximum current.

摘要： Limitations on the number of recording elements capable of being simultaneously driven are relaxed so that driving voltage fluctuation falls within an allowable range. The substrate includes arrays of recording elements, common power supply wires extended from portions near one end portions of the arrays to portions near the other end portions thereof and connected to a power supply-side electrode pad through a position near the one end portions of the arrays, and common ground wires extended from portions near the one end portions of the arrays to portions near the other end portions thereof and connected to a ground-side electrode pad through a position near the other end portions of the arrays. Thus, since the sum of the lengths of common wires from the electrode pads is equal for all the plurality of elements included in each array, and the combined resistance of common wiring portions becomes substantially equal.

摘要： Disclosed is a printing head having connection terminals for performing an electrical connection of signals including drive signals of print elements by contacting connection terminals in an apparatus side when the head is mounted onto an ink jet printing apparatus. It is made to guarantee connections of all terminals by detecting contacts of a part of terminals. Among the terminals in the head, terminals whose distances from the connection terminals in the printing apparatus become maximum when a deviation occurred in the mounting, are used as terminals for contact detection. For example, from among the connection terminals arranged in a planar area, which is rectangular-shaped, terminals positioned in corners are used as the terminals for the contact detection. When the contacts of these terminals are detected, the connections of all the terminals inside the area can be guaranteed.

摘要： An inkjet recording apparatus includes a heating unit configured to produce thermal energy for discharging ink, and two electrodes which electrically connect with each other through the ink. Voltage is applied between the two electrodes, and a current value flowing through the ink is measured. Whether the ink is discharged or not is determined by determining whether the current changes when the heating unit is driven.
