Abstract
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.
Claims6
An ink jet recording apparatus to which an ink tank is removably mountable, the ink tank being provided with a component of electrical conduction and an ink supply port, said ink jet recording apparatus for recording by discharging ink supplied from the ink tank from an ink jet recording head, said ink jet recording apparatus comprising:
- a mounting surface for mounting the ink tank;
- a connector arranged at a first position of said mounting surface, said connector being provided with an electrical contact electrically conductible with the component of electrical conduction of the ink tank when mounted on said mounting surface, and an electrical contact supporting unit on said connector for supporting said electrical contact;
- and
- an ink outlet port arranged at a second position of said mounting surface, said ink outlet port being communicated with the ink supply port of the ink tank when mounted on said mounting surface;
- wherein said electrical contact is positioned on said electrical contact supporting unit so that said electrical contact supporting unit shields electrical contact with the component of electrical conduction of the ink tank from ink from said ink outlet port.
