液体排出装置
摘要：
本发明提供具备充分地完成抗噪对策且在信号的传输速率较大的情况下也能够对应的电缆的液体排出装置。该液体排出装置具有第1压电元件PTZ(1)；第1空腔CA(1)；第1喷嘴NZ(1)；第2压电元件PTZ(2)；第2空腔CA(2)；第2喷嘴NZ(2)；驱动信号生成部(14)，其生成使第1压电元件或者第2压电元件位移的驱动信号；驱动信号传递路径，其将驱动信号从驱动信号生成部向第1压电元件或者第2压电元件传输；以及电缆(20)，其构成驱动信号传递路径的至少一部分，电缆包括：构成驱动信号传递路径的至少一部分的驱动信号传输线；和电位被固定的屏蔽线，驱动信号传输线具有规定范围的特性阻抗。
摘要（英）：

A liquid ejecting apparatus includes a first piezo-electric element (1); a first cavity CA (1); a first nozzle NZ (1); a second piezo-electric element PTZ (2); a second cavity CA (2); a second nozzle NZ (2); a drive signal generating section (14) which generates a drive signal causing the first piezo-electric element or the second piezo-electric element to be displaced; a drive signal transmission path through which the drive signal is transmitted from the drive signal generating section to the first piezo-electric element or the second piezo-electric element; and a cable (20) that forms at least a portion of the drive signal transmission path, the cable includes a drive signal transmitting wire which forms at least a portion of the drive signal transmission path and a shield wire in which potentials are fixed, and the drive signal transmitting wire has a characteristic impedance in a predetermined range.
