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 substrate for a recording head includes a circuit through which current flows upon impression of a source voltage, irrespective of the operating state of an energy converting element, and a current cutoff means for cutting off current to the circuit in response to an entered control signal. A reset signal for achieving a standby state of the printing operation serves as the control signal. The current cutoff circuit is operated when the reset signal is active in an H state, and it cuts off the constant current. By cutting off the constant current, the leak current of a heater power source VH may be accurately measured, permitting determination of whether the source voltage wiring is properly insulated from other circuit elements of the substrate. The constant current may also be cut off in the standby state, in which printing is not performed, so as to reduce power consumption.

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： An ink tank is provided which can efficiently perform detection of information in an ink tank such as an ink residual amount in the ink tank with a simple configuration in which it is unnecessary to set wiring or the like. A solid semiconductor element, which is provided with an acquiring unit for acquiring environmental information of the outside, an information storing unit, a discriminating unit for comparing acquired information and stored information to make a determination, and an information communicating unit for displaying the acquired information or communicating the acquired information to the outside, is embedded in an outer wall of an ink tank such that the solid semiconductor element is exposed to an internal side and an external side of the ink tank from the outer wall. The solid semiconductor element can perform supply of its operation energy or exchanges of signals in a non-contact state or by connecting with a terminal provided in a supporting portion or the like of the ink tank directly, thus, it is unnecessary to set wiring. In this case, the information acquiring means can be preferably disposed in the part of the solid semiconductor element exposed to the inside of the ink tank.

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.
