CONNECTING DEVICE FOR LIQUID SUPPLYING MEMBER AND LIQUID SUPPLYING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a joint and a liquid supplying system capable of supplying a liquid to a relaying passage for relaying a liquid supplying hole of a liquid tube to a liquid receiving section at an ink jet head side without generating bubbles. SOLUTION: There is disclosed a joint for connecting a liquid supplying hole 14a of a liquid supplying tube 14 to a liquid receiving section 11a at a side of an ink jet head 11 with a relaying liquid passage 1a therebetween. An inner wall adjacent to the liquid supplying hole 14a is formed in a tapered-shape such that the relaying liquid passage 1a is gradually expanded as it goes from the liquid supplying hole 14a to the liquid receiving section 11a.
