    • An element substrate is provided to prevent length increase in a direction vertical to a segment arrangement direction, and a print head, a head cartridge and a printing apparatus using the element substrate are provided. An element substrate comprises an electrothermal transducer selection circuit, a level converter(116) and a selection circuit(117). The electrothermal transducer selection circuit divides a plurality of electrothermal transducers into a plurality of blocks, receives a block enable signal and a print data signal for selectively driving the blocks in time-sharing method and outputs the driving signal. The level converter is provided for a plurality of switching element groups corresponding to the adjacent electrothermal transducers, and steps up an input driving signal. The selection circuit selects supply destination of the driving signal output from the level converter among adjacent switching elements based on a selection signal input from the outside.
    • 提供元件基板以防止沿垂直于分段布置方向的方向的长度增加,并且提供使用该元件基板的打印头,打印头盒和打印装置。 元件基板包括电热转换器选择电路,电平转换器(116)和选择电路(117)。 电热转换器选择电路将多个电热换能器分成多个块,接收块使能信号和打印数据信号,用于以分时方式选择性地驱动块并输出驱动信号。 电平转换器被设置用于对应于相邻电热换能器的多个开关元件组,并且升高输入驱动信号。 选择电路基于从外部输入的选择信号,在相邻的开关元件中选择从电平变换器输出的驱动信号的供给目的地。
