TANK UNIT FOR SUPPLYING LIQUID TO LIQUID JETTING APPARATUS, AND LIQUID JETTING SYSTEM INCLUDING TANK UNIT AND LIQUID JETTING APPARATUS

摘要

Provided is a technique for allowing a test for a tank to be performed in a simple manner. A tank unit 20A has a plurality of ink tanks 25A, a substrate part 80, and a casing part 21A. Each ink tank 25A includes electrode pins 70a and 70b used for detection of ink IN. The substrate part 80 is connected to back ends 72a and 72b of the electrode pins 70a and 70b protruding outside of the ink tanks 25A. The casing part 21A stores the ink tanks 25A and the substrate part 80. Through windows 92 that expose the electrode pins 70a and 70b to the outside are provided in the back face of the casing part 21A.
