US 2010/0245499 A1 · INJECTION APPARATUS AND A VALVE DEVICE PROVIDED IN A PASSAGE

Abstract

An ink jet type recording apparatus comprises a connection member which has a passage for leading ink to a recording head from an ink cartridge. In the passage, a valve member having a magnetic body is provided. A rotation member has a permanent magnet and is rotatable between a first position and a second position. When the rotation member is located in the first position, an attraction that can move the valve member in an opening direction of the passage acts between the magnet and magnetic body, and hence, the valve member opens the passage. When the rotation member is located in the second position, the attraction that can move the valve member does not act between the magnet and magnetic body, and hence, the valve member closes the passage.
