Description

[Title of the Invention] ink cartridge

[0001]
Field of the Invention
The present invention relates ink ink cartridge for supplying a proper negative pressure state to a recording head for ejecting ink droplets in response to print signals.

[0003]
[Problems to be solved by the invention]
However, when the ink cartridge is mounted by rotation, it is difficult to apply to an ink container in which an ink flow path is formed via an ink supply needle communicating with the recording head.
That is, since the ink supply needle has a predetermined length in order to ensure reliable communication with the ink container, there is a possibility that the ink container may be broken if it receives an external force other than in the axial direction. It is necessary to move parallel to the longitudinal direction.
Further, as disclosed in JP-A-9-11500, an elastically deformable lever having a claw portion engaged with an ink cartridge holder is formed on two opposing surfaces of a container for containing ink to supply ink. There has also been proposed an ink cartridge which can be inserted into a needle.
Furthermore, as can be seen in JP-A-2001-105587, the container for containing the ink is formed into a flat rectangular parallelepiped shape, and a latch member is provided on the front side wall in the longitudinal direction. There has been proposed an ink cartridge in which a convex portion for insertion guide is formed.
However, in the case of the ink cartridge provided with the storage means storing information and the like regarding the ink cartridge, the reliable connection with the fine electrode is required, so the reliable positioning is required.
The present invention was made in view of such problems, it is an purpose of that is possible insertion into the ink supply needle and the ink cartridge, communicating with the storage means which is attached thereto Ru der to provide an ink cartridge that can be mounted in the correct position, which can be secured.

[Means for Solving the Problems]
In order to achieve such a first problem , a recording head and an ink supply needle communicating with the recording head are mounted, and an electrode connected to an electrode formed on the ink cartridge and an ink cartridge are formed. An ink cartridge configured to be attachable to and detachable from the storage area of a recording apparatus including a carriage having an ink cartridge storage area including an engagement portion engaged with a locking member A container containing ink provided with the ink supply port engaged with an ink supply needle, and a first wall parallel to the insertion direction of the container connected to the electrode formed in the storage area of the carriage And a protrusion engaging with the engaging portion of the storage area of the carriage on the rear end side in the insertion direction with respect to the electrode of the storage means and the electrode of the storage means. Comprising a locking member that, a.

【Effect of the invention】
According to the present invention described above, can be inserted into and removed from the ink supply needle and the ink cartridge, Ru can be mounted in the correct position which can ensure communication with the storage means which is attached thereto.
