    摘要： An object of this invention is to provide a printhead tolerant of switching noise occurred when concurrently driving plural printing elements, a head cartridge using the printhead, and a printing apparatus. To achieve this object, a printhead includes plural printing elements and plural driving elements for driving the plural printing elements, and prints by these printing elements. The printhead includes the following arrangement. More specifically, the printhead 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.

    摘要翻译： 本发明的一个目的是提供当同时驱动多个打印元件时产生的开关噪音的打印头容忍性，使用打印头的打印头盒和打印装置。 为了实现该目的，打印头包括多个打印元件和用于驱动多个打印元件的多个驱动元件，并且由这些打印元件打印。 打印头包括以下布置。 更具体地，打印头包括与时钟信号同步地接收打印数据的移位寄存器以及与锁存信号同步地将输入到移位寄存器的打印数据锁存的锁存电路。 该打印头还包括一个限制电路，其将打印数据和时钟信号的输入限制到移位寄存器，并且与用于驱动多个驱动元件的使能信号的输入同步地将锁存信号输入到锁存电路。
