摘要： To accurately position and fix an ink cartridge on an ink cartridge mounting unit, a first engaging depression is formed in the bottom wall of the ink cartridge and a corresponding protrusion is formed in the mounting unit. Also, an ink supply port is formed in the bottom wall. When the ink cartridge is mounted on the mounting unit, the ink supply port is engaged first with an ink supply channel formed in the mounting unit and fluidly connected to the head unit. Then, the first engaging depression is brought into engagement with the corresponding protrusion in the mounting unit. A second engaging depression is further formed in the top. The engaging pawl of a locking arm engages the second engaging depression when the locking arm locks the ink cartridge to the head unit. Further, a pair of ribs is provided on the rear side wall of the ink cartridge. The ribs oppose each other with a prescribed interval. A corresponding protrusion protrudes from the head unit and fits into the space between the interval of the ribs when the ink cartridge is mounted in the head unit.

摘要： An ink cartridge has an ink tank in which the ink is stored, and a shutter mechanism which is arranged in the ink tank. The shutter mechanism includes a lever which is supported swingably and which has one end provided with a shutter and the other end provided with a float. The mass and the volume of the float are set so that the first direction, in which the lever moves by the buoyancy and the gravity generated when the entire shutter mechanism is positioned in the ink, is opposite to the second direction in which the lever moves by the buoyancy and the gravity when a part of the float protrudes from the ink liquid surface. A residual amount of an ink is indicated without being excessively affected by any disturbance such as the surface tension of the ink.
