摘要:
This invention is directed to an element substrate including a plurality of print element arrays in which print elements are arranged at different arrayed densities. The element substrate can efficiently transfer data to each print element. The element substrate includes the following arrangement. More specifically, the first print element array having a relatively large number of print elements, and the second print element array which is equal in length to the first print element array and has a relatively small number of print elements are juxtaposed. The element substrate includes one shift register which holds data for driving the print element of the second print element array, and a plurality of shift registers for dividing and holding data for driving the print elements of the first print element array.
