打印头单元和液体喷射装置
摘要：
一种打印头单元，包括：结构体；以及驱动器IC，结构体包括多个喷射部，多个喷射部被分成第一阵列和与第一阵列不同的第二阵列，多个喷射部中的每个包括致动器并喷射与施加到致动器的一端的驱动信号相对应的液体，驱动器IC包括：第一块，其电连接到包括在第一阵列中的致动器的一端，并且将驱动信号施加到包括在第一阵列中的致动器；第二块，其电连接到包括在第二阵列中的致动器的一端，并且将驱动信号施加到包括在第二阵列中的致动器；以及第三块，其电连接到包括在第一阵列中的致动器的另一端和包括在第二阵列中的致动器的另一端，并且将保持信号施加到包括在第一阵列中的致动器和包括在第二阵列中的致动器，驱动器IC安装在结构体上使得密封包括在第一阵列中的致动器和包括在第二阵列中的致动器，并且当垂直于安装在结构体上的驱动器IC的安装表面而观察时，第三块位于第一块与第二块之间。
摘要（英）：

A head unit includes: a structure; and a driver IC, the structure including a plurality of ejection sections, the plurality of ejection sections being divided into a first array and a second array that differs from the first array, each of the plurality of ejection sections including an actuator and ejecting a liquid corresponding to a drive signal applied to one end of the actuator, the driver IC including: a first block that is electrically connected to one end of the actuator included in the first array, and applies the drive signal to the actuator included in the first array; a second block that is electrically connected to one end of the actuator included in the second array, and applies the drive signal to the actuator included in the second array; and a third block that is electrically connected to the other end of the actuator included in the first array and the other end of the actuator included in the second array, and applies a hold signal to the actuator included in the first array and the actuator included in the second array, the driver IC being mounted on the structure so as to seal the actuator included in the first array and the actuator included in the second array, and the third block being situated between the first block and the second block when viewed perpendicular to a mounting surface of the driver IC that is mounted on the structure.
