发明名称 Liquid ejection inspecting apparatus, printing apparatus, and liquid ejection system
摘要 A liquid ejection inspecting apparatus includes (A) a sensing section (70), (B) a detection circuit (80), (C) a determination section, and (D) a substrate. The sensing section is arranged in a state of non-contact with a liquid ejection nozzle for ejecting a liquid. The detection circuit is for detecting an induced current generated in the sensing section due to the liquid ejected from the liquid ejection nozzle and charged electrically. The determination section is for determining whether or not the liquid is ejected from the liquid ejection nozzle normally, based on the induced current detected by the detection circuit. The substrate is provided with the sensing section and a circuit component that constitutes the detection circuit. The sensing section is provided on one surface of the substrate. The circuit component that constitutes the detection circuit is provided on the other surface of the substrate.
