In an ink jet recording apparatus, ink is supplied from a recording ink tank to a recording head, and ink droplets are ejected from the ejection openings of nozzles provided in the recording head. Ink tanks include those that supply ink to the nozzle portions of the recording head through a suitable ink supply pipe provided separately from the recording head, and those that are integrally attached to the recording head.

出異常を生ぜしめることがある。 Incidentally, in an inkjet recording apparatus, dust or air bubbles may get mixed into the ink tank or the communication portion between the tank and the nozzle. The nozzle of the recording head generally has a thin inner diameter of several tens of microns, so when the dust and air bubbles reach the nozzle of the recording head, they adhere inside the nozzle and obstruct the flow of ink, reducing ink ejection efficiency. This may reduce the ejection response to the recording signal or eventually cause clogging, making it impossible to eject ink. Furthermore, if an inkjet recording device is not ejected for a long period of time while being filled with ink, constituent components of the ink may precipitate and similarly cause ink ejection abnormalities.

たりするという難点があつた。 Therefore, it is important to restore ink ejection from the nozzles. In order to recover such ink ejection, conventionally, obstructions such as dust inside the nozzle have been removed by capping the ink ejection opening of the nozzle from the outside and suctioning the ink ejection port from the outside. However, in order to implement such a method, it is necessary to create an ink ejection recovery device separately from the recording head, which makes it difficult to make the recording device more compact with the conventional method, and furthermore, the ink ejection recovery device has to be manufactured separately from the recording head. The positional accuracy between the outlet position and the suction hole attached to the capping mechanism must be ensured, making assembly of the device difficult, and if this positional accuracy is poor, the outlet may be damaged during use. There was a problem with that.
〔発明の目的〕
本発明は、以上の如き従来技術に鑑み、記録装

According to the present invention, the above object is achieved by providing a deformable ink bag for storing ink in a case, forming a low-strength portion in a component of the case,
This is achieved by forming a lever that can be rotated to a position where the ink bag is pressed by breaking the low-strength portion.

ラスチツクにより構成されている。 FIG. 1 is a schematic perspective view showing a first embodiment of the ink tank of the present invention, and FIG. 2 is a sectional view thereof. In this embodiment, an ink tank is constructed integrally with a recording head. In the figure, 1 is the nozzle plate of the recording head, and the ink ejection openings 2 of the nozzles are on the surface of the plate.
is open. The nozzle plate 1 also serves as a case for the ink tank. Reference numeral 3 denotes an ink tank case, which is connected to the nozzle plate 1, thereby forming a space for accommodating ink. An ink bag 4 for storing ink is arranged within this space. Ink 5 is stored in the ink bag 4, and the ink bag 4
The inside communicates with the ink discharge ports 2 of each nozzle via appropriate ink flow passages (not shown). Two notches 6 and 7 are provided on the upper surface of the case 3, and one end thereof faces each other via a relatively narrow connecting portion 8. In this embodiment, the case 3 is made of plastic, such as ABS resin, which can sufficiently withstand repeated bending.

FIG. 2 is a cross-sectional view similar to FIG. 2; Notch 6 of case 3
The lever 10 is formed by pushing the portion between and 7 from above with a coin 9 or the like to break the connecting portion 8 of the case 3. Since the constituent members of the case 3 are made of a material with good durability against bending force, the lever 10 can rotate about the fulcrum 11, thereby pressing the ink bag 4. The pressure of the ink 5 is increased by the pressure of the ink bag 4, and the ink is ejected from the ejection port 2 with strong pressure, thereby eliminating the ink ejection abnormality of the nozzle.
