摘要： A stable operation is realized without any malfunction of a driver even under a voltage condition that a supplied voltage is 3.3 V or lower. For this purpose, in an ink-jet printhead having an ink orifice for discharging ink, a plurality of heat generation elements for generating heat energy used to discharge ink, and an ink channel which incorporates the heat generation elements and communicates with the ink orifice, a driver for driving the heat generation elements, and a logic circuit for controlling the driver are formed on a single board. The gate oxide film thickness of an enhancement NMOS transistor which forms the driver is larger than that of an enhancement NMOS transistor which forms the logic circuit.

摘要： Printhead substrate for inputting a data signal (DATA) in synchronization with a clock signal (CLK). The printhead substrate comprises: input terminals inputting the clock signal and data signal; shift registers inputting and maintaining the data signal in synchronization with the clock signal inputted from the input terminals; and a time lag adjuster arranged between an input terminal and the shift register to adjust a time lag of at least one of the clock signal or data signal. By virtue of adjusting the time lag by the time lag adjuster, setup time and hold time between the clock signal and the data signal inputted to the shift register is ensured.

摘要： This invention provides a printing head which can prevent an increase in the number of block enable signal lines, and can prevent changes in printing ink density caused by interference due to the relative pressures of nozzles generated in ink discharge, and an image printing apparatus using the printing head. For this purpose, an increase in the number of input signal lines along with an increase in the number of blocks is prevented using a block clock signal or the like instead of a block enable signal as an input signal to the printing head. Three ring counters generate signals having different nozzle driving orders. These signals are selectively used by a ring counter selection signal. Ink is not always discharged from the nozzles in the same output order. This can prevent changes in ink density caused by pressure interference.
摘要翻译：本发明提供一种打印头，其能够防止块启用信号线的数量的增加，并且可以防止由于在喷墨时产生的喷嘴的相对压力而引起的干扰引起的打印油墨浓度的变化，以及使用打印头。为此，使用块时钟信号等代替块使能信号作为打印头的输入信号来防止输入信号线的数量的增加以及块数量的增加。三个环形计数器产生具有不同喷嘴驱动顺序的信号。这些信号由环计数器选择信号选择使用。墨水并不总是以相同的输出顺序从喷嘴排出。这可以防止由压力干扰引起的墨密度变化。
