An inkjet recording apparatus comprises an inkjet recording head, an ink-testing unit having an ink-test chamber, a pressure-vibration generating unit that generates a pressure vibration in the ink-test chamber, a pressure-vibration detecting unit that detects the pressure vibration, an ink inlet that introduces ink into the ink-test chamber and an ink outlet through which ink is discharged from the ink-tester chamber. Failures of ink ejection can be prevented by detecting cavitation cores by the ink-test chamber and removing ink containing the cavitation cores from ink supplied to the inkjet recording head.

(1) Field of the Invention
The present invention relates to an inkjet recording apparatus, particularly to an inkjet recording apparatus that prevents failures of ink-ejection.
(2) Description of the Related Art
These and other objects and advantages of this invention will become apparent and more readily appreciated from the following detailed description of the presently preferred exemplary embodiments of the invention taken in conjunction with the accompanying drawings, wherein:
FIG. 1 is a schematic diagram of an inkjet recording apparatus according to one embodiment of the present invention;
FIG. 2 is a schematic diagram of an ink supply system according to the same embodiment of the present invention;
The present invention will now be described in more detail with reference to the accompanying drawings. However, the same numerals are applied to the similar elements in the drawings, and therefore, the detailed descriptions thereof are not repeated.
The preferred embodiment according to the present invention will now be described below. “Ink” referred in the present invention includes not only a coloring material that merely forms characters or images but also a liquid that is ejected onto a printed medium by an inkjet recording apparatus including, e.g., electrically conductive materials used for forming wiring patterns of an electric circuit. The printing material also referred in the present invention means not only recording materials such as paper that merely retains information of characters, images, or the like on its surface but also materials including a substrate used for an electric circuit on which a liquid ejected by an inkjet recording apparatus is made to be deposited.
Now, a structure of an inkjet recording apparatus according to the present invention will be described.
