The holes 972 and 982 formed therein are long and thin because it is necessary to secure the strength by increasing the thickness of the first and second 981 to some extent. Therefore, there is a problem that the pressure loss itself when the ink passes through the holes 972 and 982 is large.

[0008] In view of the above problems, an object of the present invention is to provide:
Even when the ink container is mounted horizontally,
It is an object of the present invention to provide an ink jet recording apparatus capable of forming a large number of holes for holding ink at a tip end portion of an ink introduction needle with a small pressure loss.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, there is provided an ink container which accommodates ink and is detachably attached to an ink container mounting portion of a recording apparatus main body, and supplies ink from the ink container. And a recording apparatus main body that performs recording on the medium by ejecting the ejected ink toward the medium from the recording head, wherein the ink container is arranged such that the ink container is horizontally disposed on the ink container mounting portion. An ink supply unit on a side surface located on the mounting direction side when the ink container is mounted from the direction, and the recording apparatus main body pierces the ink supply unit when the ink container is mounted on the ink container device unit. The ink introduction needle has a tip bent laterally at the position, and the ink introduction needle has a porous body separate from the needle body. Characterized in that it is fixed on the distal end side of the ink passage.

In the present invention, the tip of the needle body of the ink introduction needle is formed in a bent shape, and then a separate porous body is fixed to the tip of the needle body. Therefore, even if the tip of the ink introduction needle is bent, a large number of holes for holding ink can be formed at the tip of the ink introduction needle. Therefore, for the ink container,
When the ink container is mounted on the ink container mounting portion from the horizontal direction, the ink supply portion is disposed on the side surface located on the mounting direction side, while the ink container device device portion of the recording apparatus body is By disposing the ink introduction needle having a laterally bent tip at a position where it pierces the lateral ink supply unit when the is mounted,
An ink jet recording apparatus to which the ink container can be mounted from the horizontal direction can be realized. In such an ink jet recording apparatus, unlike the configuration in which the ink container is mounted from above the ink jet recording apparatus, it is not necessary to open the upper part of the ink jet recording apparatus, and as if looking into the ink jet recording apparatus. Since there is no need to mount an ink container, it is convenient to use.

In the present invention, the pressure loss when the ink passes through the needle body tends to be large due to the bending of the needle body. However, if the needle body and the porous body are separate bodies, In addition, a porous body having a small pressure loss when the ink passes therethrough, such as a thin net-like part as the porous body, can be used. With such a thin mesh-shaped hole, unlike the conventional elongated hole formed in the resin molded product, the pressure loss when the ink passes is small. Therefore, even if the needle main body is bent, the pressure loss when the ink passes can be reduced for the entire needle.

In the present invention, the needle main body is, for example, a resin molded product.

In the present invention, it is preferable that the ink container mounting portion is formed so that the ink container is mounted from the front of a recording apparatus main body.

In the present invention, the porous body is, for example, a thin net-like part. With such a thin net-like part, the pressure loss when the ink passes through it can be considerably reduced.

In the present invention, it is preferable that the porous body is fixed to, for example, a step formed at a position depressed from the tip inside the needle body. When the porous body is located at a position recessed from the tip of the needle main body, a large force is not applied to the porous body when the ink introduction needle pierces the ink supply unit of the ink container. Therefore, even if a thin reticulated component is used as the porous body, the reticulated component is not deformed.

Further, in the present invention, the porous body is
The needle body may be fixed to the tip of the needle body with a shape projecting hemispherically. When the porous body protrudes in a hemispherical shape as described above, a large local force is not applied to the porous body when the ink introduction needle pierces the ink supply unit of the ink container. Therefore, even if a thin reticulated component is used as the porous body, the reticulated component is not deformed.

Here, the ink cartridges 107K, 10K
7F has basically the same structure. Therefore, the internal structure and the structure of the ink introduction needle will be described only for the black ink cartridge 107K, and the ink cartridge 107F will be described. Is omitted.

FIG. 4 is a perspective view showing a schematic structure of a black ink cartridge and a cartridge mounting portion of a recording apparatus main body. FIGS. 5A and 5B are a cross-sectional view showing a state where the ink introduction needle pierces the ink supply unit of the ink cartridge, and an enlarged cross-sectional view of the ink introduction needle.

As shown in FIGS. 4 and 5A, the ink cartridge 107K has a box shape made of a resin molded product, and the inside thereof is an ink container 107K '. The ink container 107K 'is filled with a porous ink holder 172, and the ink holder 172 holds ink. Ink cartridge 107K
Has a two-body structure of a container body 170 and a cover 179 that covers the container body 170, and an ink injection port and the like are formed on the cover 179.

On the other hand, the cartridge mounting portion 18 has a box-shaped holder portion 2 capable of storing the ink cartridge 107K.
00 and a lever 210 are formed. Holder part 2
00 has an opening 201 for mounting the ink cartridge 107K horizontally from the direction indicated by the arrow A.
The opening 201 faces the front of the apparatus main body. A guide rib 171 extending horizontally in the front-rear direction is formed on a side surface of the ink cartridge 107 </ b> K.
A guide 202 that receives the guide rib 171 from below is formed on the inner wall of 00.

In the lever 210, the end portions of the arm portions 214 extending vertically are supported by the front surface of the holder portion 200 via the rotation center shaft 204. For this reason, the lever 210 is rotatable around these rotation center axes 204. In addition, holder part 2
The small projections 206 are formed on the upper surface of the 00,
A round hole 216 that fits into the small projection 206 is formed on the upper surface of the lever 210. Accordingly, after the ink cartridge 107K is horizontally inserted into the holder 200 from the front of the apparatus main body as shown by the arrow A, the lever 210
Is turned, the lever 21 is
The protrusion 219 of the ink cartridge 107K
Is pushed toward the rear wall 209 of the holder section 200. As a result, the ink introduction needle 19 pierces the ink cartridge 107K. At this time, the holder 20
The round hole 216 of the lever 210 fits into the small projection 206 formed on the upper surface of the ink cartridge 107K, so that the ink cartridge 107K is fixed inside the holder 200.

Since the knob portion 213 which is curved and protrudes is formed at the free end side end of the lever 210, the lever 210 can be easily opened by dragging a fingertip there. . Therefore, the ink cartridge 107K can be easily removed from the holder section 200.

In the ink jet recording apparatus 1 configured as described above, as shown in FIGS. 5A and 5B, an ink introduction needle 19 is arranged at the back of the cartridge mounting section 18 (holder section 200). The ink introduction needle 19 of
After rising vertically from the bottom 183 of the cartridge mounting portion 18, the distal end portion 191 has a structure bent forward.

Therefore, as shown by the arrow A, the ink cartridge 107K is inserted into the holder 20 of the recording apparatus main body 100.
A cylindrical ink supply section 174 is formed at a position where the ink supply needle 19 contacts the ink introduction needle 19 when the ink supply section 19 is pushed into the inside of the cylinder. A horizontal ink passage 175 passes through the inside of the ink supply section 174, and a filter 176 is disposed at an entrance to the ink passage 175, and a rubber packing 177 is disposed at an exit. Therefore, when the ink cartridge 107 </ b> K is pushed into the cartridge mounting portion 18 horizontally from the front, the tip portion 191 of the ink introduction needle 19 enters the ink passage 175 so as to pierce the ink supply portion 174. The liquid tightness in this state is ensured by the rubber packing 177.

Here, the ink introduction needle 19 is shown in FIG.
As shown in FIG.
The needle main body 190 has a shape in which, after rising vertically from the cartridge mounting portion 18 side, the distal end portion 191 is bent forward. Needle body 190
When viewed from the upper end side, the base has a considerably swelled shape, and the ink passage 196 has a widened shape at the swelled portion. The needle main body 190 is fixed to the cartridge mounting portion 18 while ensuring watertightness with an adhesive 188 or the like on the cartridge mounting portion 18 side.

The ink passage 196 on the needle body 190 side and the ink passage 18 on the cartridge mounting portion 18 side
7, a filter 199 having a finer size of 15 μm to 20 μm is arranged.

The needle main body 190 thus configured can be formed as an integrally molded product of resin. However, in such a shape, the needle main body 190 has a large number of holes for holding ink at the time of resin molding. It cannot be formed on the tip 191. Therefore, in the present embodiment, the ink introduction needle 19
Uses a porous body 195 separate from the needle body 190. That is, the porous body 195 is
90 is a net-like part formed separately from the needle body 190.
Is fixed to the tip side of the ink passage 196. As the fixing structure, in the example shown in FIG.
A porous body 195 is fixed to a stepped portion 197 formed in an annular shape at a position depressed from the tip portion 191 of the base member. The porous body 195 has, for example, a large number of holes 1 of about 0.2 mm.
It is a net made of stainless steel or the like with 94. Accordingly, at the tip 191 of the ink introduction needle 19, the ink is always held in a state where a meniscus is formed by the hole 194 of the porous body 195.
Even when replacing the 07K, air does not enter the inside of the ink introduction needle 19.

Such a mounting structure is the same for the color ink cartridge 107F.

As described above, in the ink jet recording apparatus 1 of the present embodiment, when the ink introduction needle 19 is formed,
After forming the needle main body 190 so that the distal end portion 191 is bent, a separate porous body 195 is fixed to the distal end portion 191 of the needle main body 190. Therefore, since the tip 191 is the bent ink introduction needle 191, even if the ink holding hole cannot be formed at the same time during the resin molding, the porous body 1 can be formed.
With 95, a number of holes 194 for holding ink can be formed in the tip 191 of the ink introduction needle 19.
Therefore, with respect to the ink cartridges 107K and 107F, the ink supply unit 174 is disposed at a position located on the mounting direction side when the ink cartridges 107K and 107F are mounted horizontally from the front, while the recording apparatus main body 100 has the cartridge supply unit 174. The ink cartridge 10
By arranging the ink introduction needle 19 having the tip portion 191 that is bent laterally at a position where it pierces the ink supply unit 174 of 7K and 107F, it is possible to realize the ink jet recording apparatus 1 in which the ink cartridges 107K and 107F can be mounted horizontally.

In such an ink jet recording apparatus 1, unlike the configuration in which the ink cartridges 107K and 107F are mounted from above, it is necessary to leave a space above the ink jet recording apparatus 1 for mounting the ink cartridges 107K and 107F. Therefore, the ink jet recording apparatus 1 can be arranged at the middle of the rack or the like, and need not be arranged at the top of the rack. Further, it is not necessary to mount the ink cartridges 107K and 107F so as to look into the ink jet recording apparatus 1. Therefore, easy-to-use inkjet recording apparatus 1
Can be realized.

Further, in the present embodiment, the pressure loss when ink passes through the needle body 190 tends to increase due to the bending of the needle body 190. However, the needle body 190 and the porous body 195 are separately provided. Since it is a body, a thin reticulated part can be used as the porous body 195. For this reason, unlike the conventional elongated hole formed in the resin molded product, if the hole 194 is formed in a thin net-like component, the porous body 1
The pressure loss when the ink passes through 95 is small. Therefore, the pressure loss when the ink passes through the ink introduction needle 19 can be considerably suppressed as a whole.

Further, in this embodiment, since the porous body 195 is located at a position recessed from the tip 191 of the needle main body 190,
When the ink introduction needle 19 is in the ink cartridge 107K,
A large force is not applied to the porous body 195 when piercing the 7F ink supply unit 174. Therefore, the porous body 19
Even if a thin net-like part is used as 5, this net-like part does not deform.

[Other Embodiments] In the above embodiment, the porous body 195 is fixed to the step portion 197 formed at a position recessed from the tip portion 191 inside the needle main body 190. As shown in FIG.
As an alternative, a thin net-like part having an opening of about 0.2 mm may be processed into a hemispherical shape, and may be fixed so as to protrude from the distal end portion 191 of the needle main body 190. Even with such a configuration, since the porous body 195 protrudes in a hemispherical shape, the ink introduction needles 19 need to be connected to the ink cartridges 107K and 107F.
When the porous body 19 is pierced into the ink supply portion 174 of the
5 does not receive a large force locally. Therefore, even if a thin net-like component is used as the porous body 195, the net-like component does not deform.

[0048]

As described above, in the ink jet recording apparatus according to the present invention, a separate porous body is fixed to the tip of the needle body whose tip is bent as the ink introduction needle. Therefore, even if the tip of the ink introduction needle is bent, a large number of holes for holding ink can be formed at the tip of the ink introduction needle. Therefore, it is possible to realize an ink jet recording apparatus in which the ink container can be mounted in the horizontal direction. In such an ink jet recording apparatus, unlike the configuration in which the ink container is mounted from above the ink jet recording apparatus, the upper part of the ink jet recording apparatus is opened. There is no need to put the ink container in a state, and it is not necessary to mount the ink container so as to look into the ink jet recording apparatus.

Further, in the present invention, the pressure loss when the ink passes through the needle body tends to increase due to the bending of the needle body, but if the needle body and the porous body are separate bodies, In addition, a thin reticulated component can be used as the porous body. With such a thin net-shaped part, unlike the conventional elongated hole formed in the resin molded product, the pressure loss when the ink passes is small, so that the ink passes through the ink introduction needle as a whole needle. The pressure loss at the time can be greatly reduced.
