摘要:
A printhead tolerant of switching noise that occurs when concurrently driving plural printing elements, a head cartridge using the printhead, and a printing apparatus can be provided. The printhead includes plural printing elements and plural driving elements for driving the plural printing elements, and prints using these printing elements. The printhead also includes a shift register which receives print data in synchronism with a clock signal, and a latch circuit which latches the print data input to the shift register in synchronism with a latch signal. The printhead further includes a restriction circuit which restricts input of the print data and clock signal to the shift register and input of the latch signal to the latch circuit in synchronism with input of an enable signal for driving the plural driving elements.
