摘要： A printing head according to the present 'invention resets the count value of a counter (11) in response to an externally supplied signal RESET, and thereafter, counts a signal CLK supplied upon input of an image signal (DATA). A decoder (12) generates a selection signal (B1 - B4) in accordance with the count value, thereby selecting a divided heat-generating element group in units of 32 clocks. Furthermore, an electric current is supplied to heat-generating resistors which belong to the selected heat-generating element group (34), thereby performing a printing operation. With this printing head, a printer, which can be controlled by a smaller number of control signals, can be realized.

摘要： The invention relates to a recording head and apparatus as well as to a substrate usable for the recording head. The substrate comprises electrical contacts for external electrical connection in order to receive image signals used for driving recording elements. A logic circuit converts the image signals which are serially supplied to the electrical contacts into parallel signals to be applied to the recording elements via electrical leads. The electrical contacts, the recording elements, the logic circuit, and selectors for selectively driving the recording elements are built in the substrate. The selectors are disposed in a one-to-one relation with the recording elements, corresponding to the interval of the recording elements.

摘要： A head substrate for an ink jet head that discharges ink liquid retained in the ink retaining portion by the ink discharge mechanism in accordance with the printing data inputted from the outside into the data input portion comprises one base substrate having a specific position on the surface for the ink retaining portion to be arranged, and a fuse array storing various readably data freely by selective fusing. This head substrate further comprises a fuse logic circuit for controlling the operation of selective fusing of the fuse array and data reading. Then, the fuse array and the fuse logic circuit are arranged in a position in the direction orthogonal to the surface of the base substrate, but not overlapping with the ink retaining portion. With the fuse array and fuse logic circuit thus structured, this head can be made smaller and lighter in a better productivity as compared with a head for which a ROM chip should be installed separately. Also, it becomes possible to prevent any crack that may occur due to the local heat generated by fusing of the fuse array from being developed into the ink retaining portion for the reliable operation of the head.

摘要： A substrate for use of an ink jet recording head is provided with a plurality of heat generating members for generating thermal energy to be utilized for discharging ink. The heat generating members are structured by thin film formed by material represented by Tax Siy Rz, which has specific resistance value of 4000 mu OMEGA .cm or less, where R is one or more kinds of elements selected from among C, O, N, and x + y + z = 100. With the structure thus arranged, the heat generating members make it possible to maintain the change of resistance values within a small amount even when used continuously for a long time, and provide recorded images in high quality with long life and reliability.
