摘要： A buffer circuit for shaping a waveform of a logic signal is arranged where a line for a logic circuit included in a recording-head substrate is divided into substantially equal portions, the line having an unignorable parasitic component due to its increased length. Therefore, the recording-head substrate, a recording head using the recording-head substrate, and a recording apparatus including the recording head are capable of minimizing the adverse effects of parasitic resistance and parasitic capacitance in lines even when the length of a heater array is increased.

摘要： A power supply-heater wiring and a heater-driving circuit wiring for a heater located on the right side of a supply port can be laid out utilizing a beam portion configured to separate supply ports from each other. Furthermore, a plurality of supply ports are provided to supply ink to channels and pressure chambers and separated from one another by beam portions. Thus, an ejection structure such as an ejection opening can be located on both sides of each of the supply ports. Even if the ejection structures are relatively densely arranged, the heaters and the like can have necessary and sufficient sizes and locations without being restricted by the arrangement. A wiring connecting the heater to the power supply wiring or driving circuit is also laid out on the beam portion serving as a partition wall for the supply ports.

摘要： An object of the present invention is to provide an ink jet print head configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. To achieve the object, an individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber 40 are made symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of a pressure chamber 40.

摘要： A print head that ejects ink supplied through an ink supply port can prevent the size of satellites from being reduced while inhibiting an increase in resistance to an ink flow. In the print head, ink supply ports are arranged on both sides of a plurality of channels. A predetermined number of ink supply ports are arranged at least one side of the ink channel all over the range of the arrangement of the channels. One side of each of the plurality of channels is connected via the common liquid chamber to the liquid supply port located so as to extend in a direction in which the channels are arranged.
