ELEMENT SUBSTRATE, PRINTHEAD, HEAD CARTRIDGE, AND PRINTING APPARATUS
摘要:
An element substrate includes a plurality of printing elements, a plurality of driving circuits which drive the plurality of printing elements, an input unit which inputs an enable signal to define the driving period of each printing element, a shift register which inputs a print data, a latch circuit which stores, in accordance with an externally input latch signal, the print data output from the shift register and outputs a print data signal, a time-divisional selection circuit which generates a block selection signal to divide the plurality of printing elements into a plurality of blocks and time-divisionally drive the printing elements, and a delay unit which changes the drive timing between the printing elements in a single block. The delay unit delays the enable signal and the print data signal.
