Apparatus for ejecting liquids, ejection detection apparatus, and ejection detector

An ejection detection apparatus for detecting whether liquids are ejected from a nozzle of a liquid ejection head comprising:

• an insulated receiver having an adhering face to receive and adhere the liquids ejected from the nozzle;
• and
• an electrode disposed on an opposite side of the adhering face of the receiver,
• wherein the ejection detection apparatus detects electrical change generated when the liquids adhere to the adhering face of the receiver while generating a potential difference generated between the liquid ejection head and the electrode.

An ejection detector for detecting whether liquids are ejected from a nozzle of a liquid ejection head comprising:

• an insulated receiver having an adhering face to receive and adhere the liquids ejected from the nozzle;
• and
• an electrode disposed on an opposite side of the adhering face of the receiver,
• wherein the ejection detector detects electrical change generated when the liquids adhere to the adhering face of the receiver while generating a potential difference generated between the liquid ejection head and the electrode.
