摘要： This invention relates to an integrated printhead (20) for ink jet printers, wherein the addressing of the various nozzles is effected in at least 3-D mode. The head (20) comprises a plurality of groups (24) of ink jet elements (21, 22) arranged in M rows and L columns wherein, in particular, the selection and activation of the different columns L are performed, under the control of an external drive circuit, by means of logic circuits (25) inside the head itself (20). The head (20) is advantageous with respect to the known art in that it does not require control of the L columns under critical conditions such as highly variable electric currents with very high peak values.

摘要： The number of signal lines of a cable between a controller and a carriage is small, and the printing timing of each head is adjustable in units each smaller than one pixel. The signal lines include a signal line for serial printing data including printing data arranged in a predetermined order for printing heads, a signal line for a clock corresponding to each bit of the data, a signal line for a signal HDSL [1..0] representing that the printing data included in the serial printing data corresponds to which printing head, and signal lines for the signals for driving the heads. Before transferring data, one slice section corresponding to the time slot for transferring the unit printing data for each head is divided into sections, and further the sections are divided into subsections the number of which is equal to the number of print heads. The transfer of printing data is started from arbitrary subsection independently for each head.

The shift circuit includes a power signal line, a grounding signal line, a first shift signal line, a second shift signal line, a plurality of diodes, a plurality of grounding resistors, a plurality of thyristors, a cascaded resistor and a capacitor. The capacitor connects between the gate of the first thyristor and the first shift signal line. Therefore, the capacitor is charged during the off time of the period of the first clock signal, and starts to be discharged from an edge between the on time and the off time of the period of the first clock signal. During the on time of the period, the capacitor is fully discharged. Such that, the gate voltage of the first thyristor is sufficient to turn on the first thyristor and will not affect the following shift action.
