Abstract

An element substrate comprises a plurality of stages of shift registers that inputs and holds a serial data signal; a latch circuit that latches the serial data held by the shift registers; a decoder circuit that inputs an output of the latch circuit and outputs a selection signal for selecting a block of the print elements or the memory elements; and a mask circuit that masks the output of the selection signal for selecting the block of the memory elements from the decoder circuit in accordance with an input bit data signal. The block of the print elements or the memory elements includes a plurality of print elements or memory elements in which one element is selected in each of the plurality of groups.
