In a replaceable ink tank, a structure has been devised in which air bubbles are less likely to enter from a connection portion with a recording head and ink does not leak. As a conventional technique for extracting ink from an ink tank, there is a technique described in JP-A-3-92356. As shown in FIG. 5, a rubber stopper 31 is provided at the ink outlet 34 at the bottom of the ink tank 30, and a metallic ink supply needle 32 is inserted into the rubber stopper 31 to extract ink.
Since the ink supply needle 32 penetrates the rubber stopper 31, a stainless pipe is drawn so that the needle has a sharp tip, and an ink supply hole 33 having a diameter of about 1 mm is formed on the side surface of the pipe as an ink flow path. It was provided.

It is effective to maintain a negative pressure of about 30 to -100 mmAq (head). Especially in the ink jet recording apparatus in which the recording head and the ink tank are mounted on the carriage,
It is difficult to adjust the ink supply pressure by the installation height of the ink tank, and a negative pressure is generated inside the ink tank by using a porous absorbent or the like.

要因となっている。However, in the above-mentioned conventional technique, when the ink tank is replaced, the ink supply hole comes into contact with the atmosphere, so that a concave meniscus is generated. However, in the conventional stainless ink supply needle, the ink supply hole is about 1 mm. Therefore, the meniscus has a large volume, and a large amount of bubbles flow to the recording head when the ink tank is replaced, which is a factor that causes defective printing.

The present invention provides an ink jet recording apparatus equipped with an expensive, low-cost, and safe ink supply device.

通気孔である。FIG. 1 is a diagram showing an embodiment of an ink tank used in an ink jet recording apparatus according to the present invention. The ink tank 1 has a slightly tapered inside and a porous absorbent 2
The ink is held and stored in the porous absorbent 2. There is a filter 5 made of nylon fiber or stainless fiber in the ink outlet 3 below the ink tank 1 pressed against the porous absorbent 2. The filter 5 is fixed by heat welding or an adhesive. A film 4 is welded or adhered to the outside air side of the ink outlet 3. A space 8 is formed between the film 4 and the filter 5 and filled with ink. In the space 8, two packings 6 (6a, 6b) held between the ink outlet 3 and the film 4 are stacked and attached. Has been done. In addition, 7 is a ventilation hole.

る。FIG. 2 is a view showing an embodiment in which the recording head 10 and the ink tank 1 arranged on the carriage 12 are installed. The recording head 10 is fixed to the carriage 12,
The ink tank 1 is a guide 13 formed on the carriage 12.
Insert from above along. When the ink tank 1 is inserted until it hits, the ink supply needle 9 breaks the film 4,
The ink supply hole 9 a at the tip of the ink supply needle 9 projects into the space 8. At the same time, the inner circumference of the packing 6 held between the ink take-out port 3 and the film 4 and the outer circumference of the ink supply needle 9 are in close contact with each other, and the seal of the connecting portion between the ink tank 1 and the ink supply needle 9 is secured. Incidentally, 14 is a recording paper.

小量に抑えることができる。FIG. 3 is a diagram showing details of the ink supply needle 9 when the ink tank 1 is replaced. The tip of the ink supply needle 9 has a conical shape, and a plurality of ink supply holes 9a having a diameter of 0.3 mm are formed in the conical surface. A meniscus 15 is formed in the ink supply hole 9a as shown in FIG. However, since the diameter of the ink supply hole 9a is as small as 0.3 mm, the volume of the meniscus 15 is sufficiently small compared to the case of a large diameter ink supply hole. Therefore, when the ink tank 1 is replaced, the amount of air entering through the ink supply hole 9a can be suppressed to a minute amount.

９であっても容易に貫通できる。The film 4 has a three-layer structure of polystyrene, aluminum and nylon. Ink tank 1 for film 4
A film layer having an excellent gas barrier property for preventing air from entering therein is provided, and aluminum is used in this embodiment. It is also possible to use stainless steel, polypropylene or the like instead of aluminum. The ink tank 1 is made of polystyrene, and the polystyrene surface of the film 4 and the polystyrene of the ink tank 1 are heat-sealed to form the film 4
Is stuck. Since the total thickness of the film 4 is about 50 μm, which is sufficiently thin, even a highly safe ink supply needle 9 formed by resin molding can be easily penetrated.

得られる。Here, consider the case where the ink tank 1 is left in a place where the temperature exceeds 40.degree. If the ink tank 1 is inserted into the ink supply needle 9 while the ink tank 1 is still hot after the standing, the film 4 stretches more than usual when the ink supply needle 9 breaks the film 4. Therefore, as shown in FIG. 4, the stretched film 4 may enter between the ink supply needle 9 and the lower packing 6b to form a gap 17, and the seal may not be sufficiently secured only by the packing 6b. However, since the packing 6a is provided between the ink outlet 3 and the film 4 so as to overlap the packing 6b, even if the stretched film 4 may enter between the lower packing 6b and the ink supply needle 9, the packing 6a may enter. The film 4 does not enter the upper packing 6a.
Therefore, the seal of the connecting portion between the ink supply needle 9 and the ink tank 1 is secured. Further, by stacking two packings 6, it is possible to secure the seal during the insertion operation until the ink is supplied by the ink supply needle 9 and the packing 6a, if not enough, by the packing 6b. Can be kept to a minimum. In this embodiment, since an O-ring is used for the packing 6, no special shape is required, and the seal of the connecting portion can be secured at low cost. The same effect can be obtained by stacking three or more packings 6.

することができ、挿入時に大きな力を必要としない。Further, since the packing 6 is provided on the ink tank 1 side, the surface of the packing 6 is wet with the ink in the space 8 of the ink outlet 3, so that the packing 6 is generated during the insertion movement into the ink supply needle 9. The frictional force generated can be reduced, and a large force is not required at the time of insertion.

供することができる。As described above, according to the present invention, since the ink supply needle is provided with the ink supply hole having a minute diameter, it is possible to provide the ink supply device in which the invasion of the bubbles is small when the ink tank is replaced. Further, by providing two ink supply needle seal members between the ink outlet 3 and the film 4, it is possible to easily and inexpensively prevent a seal defect occurring between the ink tank and the ink supply needle, and it is highly reliable. An inkjet recording device can be provided.
