Description

[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to an inkjet recording apparatus, and more particularly to an inkjet recording apparatus in which an ink storage container for supplying ink has been improved. Conventional inkjet recording apparatuses have excellent features such as being fast and quiet, being able to print on plain paper, and being able to easily print in color. However, since a liquid is used as the recording medium, if the ink is not handled properly, the ink can contaminate the inside and outside of the apparatus, including the operator. Therefore, in order to prevent such drawbacks, an ink bag made of a flexible material that is flexible enough to respond to atmospheric pressure is used as an ink storage container, and this ink bag is housed in a rigid container. Therefore, those that are easy to handle are adopted. Such an ink bag is provided with a sealing part made of an elastic material that can be penetrated by a needle or the like, and is used to supply ink to the device (η1).
A hollow needle is provided in s, and this hollow needle is passed through the sealing part made of the elastic part (A) to constitute an ink supply path from the ink bag. A conventional example is shown in Figure 1.
The one indicated by 0 and the code 1 is inkun esotonosuru,
It is made of glass etc. The outer peripheral surface γc0 of the tip 1 of this ink jet nozzle 1
- [A piezo element 2 is wound around the inkjet nozzle 3. By applying a pulse signal, which is a printing command, to this element, the piezo element 2 is bent and vibrated, causing a volume change to the inkjet nozzle 3. Paper printing is performed by ejecting ink droplets from the tip of the inkjet nozzle 1 toward the recording paper 3. A platen 4, which also serves as a paper feed roller, is arranged opposite the inkjet nozzle 1, and the recording paper 3 is guided between the platen 4 and a pinch roller 5.6. On the other hand, the inkjet nozzle 1 is provided on a support member 7, and the support member 7 is fixed on a carriage 8. This carriage 8 moves in the main scanning direction along a guide path=9.9. On the other hand, the reference numeral 10 indicates an ink bag, and the inside thereof is filled with ink 11. The ink bag 10 is formed into a bag shape by combining individual or composite materials such as polyethylene, vinyl chloride, and aluminum foil. One end of a tube 12 is fixed to the tip side of the ink bag 10, and the other end of the tube 12 is fitted and fixed to the side of a sealing part 13 made of an FD elastic opening. The sealing part 13 is made of a material having excellent chemical resistance and flexibility, such as silicone rubber or butyl rubber, and the ink outlet hole 14 formed in the sealing part 13 is always closed. This prevents the ink 11 from flowing out from the ink bag 10. On the other hand, the one designated by numeral 15 is a hollow needle with a fixed part, I'A
16, and the fixing member 16 is fixed on the bottom plate 17. One end of the hollow needle 15 and the inkjet nozzle 1 are connected by a flexible tube 18. By the way, the ink bag 10 is housed in a case 19, and the sealing part 13 is fixed to the tip of the case 19. By the way, the cover 2 of the inkjet recording device
A flange 21 that can be opened and closed is rotatably attached to the front side of the 0 via a shaft 22. What is indicated by the dimension symbol 21a is a partition plate 9 that regulates the upper side of the housing space for the case 19 provided inside the device housing.By the way, when the structure shown above is adopted, the case 19 is installed. When the user opens the lid 21, the user manually inserts the case 19 into the interior with the sealing part 13 first and the Y::+1 side, and then inserts the hollow needle 15 into the interior.

However, even though there is a space for housing the case 19 on the device side, and since the installation is only done by hand, when the case 19 is pushed in with a certain degree of dexterity, the hollow needle 15 It is unknown to what extent it penetrates into the sealing part 13. Therefore, some users stopped inserting the case 19 immediately after feeling the resistance of the hollow needle 15 being inserted into the tube 12, and the hollow needle 15 was not supplied enough to reach the tube 12. do. Furthermore, if the case 19 is not pushed in a straight line and is pushed in crookedly, the hollow needle 15 will not reach the ink outlet hole 14 of the sealing part 13, and in this case as well, it will be impossible to draw out the ink. Become. As described above, the steps for inserting the case 19 may vary depending on individual users, and in the worst case, it may not be possible to supply ink at all. Furthermore, the only way to attach the case 19 is to open the lid 21 and do so in the water-hungry direction, and it is completely impossible to attach the case 19 from vertically upward as shown by the arrow in FIG. Purpose The present invention was made in order to eliminate the drawbacks of the prior art such as ``r1~''2, and to realize a perfect ink supply state without changing the case loading stroke depending on individual differences. In addition, it is also possible to view the case from the vertical direction.
