Element board for printhead, and printhead having the same
摘要:
In a printhead element board including a plurality of printing elements which align in a predetermined direction, driving circuits which drive the printing elements, and an element selection circuit which selects printing elements within each group for each group having a predetermined number of adjacent printing elements, a plurality of element selection circuits are laid out adjacent to the driving circuits of the respective groups. With this layout, even if the number of printing elements increases, only the length in the printing element array direction increases without increasing the length in a direction perpendicular to the printing element array direction.
