Ink jet recording apparatus and ink tank mounted on such ink jet recording apparatus

摘要

A recording apparatus is arranged to mount on the main body thereof an ink tank provided with a component of electrical conduction and an ink supply port, and structured to make ink supply and electrical connection possible. With the structure thus arranged, the adhesion of ink to the electric contacts is prevented in order to secure the reliability of electrical connection. The contacts are arranged on the side opposite to the hollow needle with a supporting member of a connector that supports plural contacts on the connector as reference.
