Abstract
Official abstract text for this publication.
An apparatus for ejecting liquids includes a liquid ejection head including a nozzle, the nozzle ejecting the liquids; and an ejection detector to detect whether the liquids are ejected from the nozzle of the liquid ejection head, the ejection detector including 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. The ejection detector detects electrical change generated when the liquids adhere to the adhering face of the receiver while generating a potential difference between the liquid ejection head and the electrode.
First claim
Opening claim text (preview).
What is claimed is: 1 . An apparatus for ejecting liquids comprising: a liquid ejection head including a nozzle, the nozzle ejecting the liquids; and an ejection detector to detect whether the liquids are ejected from the nozzle of the liquid ejection head, the ejection detector including 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 between the liquid ejection head and the electrode. 2 . The apparatus for ejecting liquids according to claim 1 , wherein the receiver and the electrode contact with each other. 3 . The apparatus for ejecting liquids according to claim 1 , wherein the receiver and the electrode are arranged apart from each other. 4 . The apparatus for ejecting liquids according to claim 1 , wherein the receiver covers the electrode. 5 . The apparatus for ejecting liquids according to claim 1 , wherein the nozzle is configured to eject the liquids which have a length reaching to the receiver from the nozzle when the ejection detector detects whether the liquids are ejected. 6 . The apparatus for ejecting liquids according to claim 1 , wherein the receiver is an insulated film formed on a surface of the electrode. 7 . 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. 8 . 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.
