  In addition, a free-rotating guide roller 23 is provided at the downstream end of the conveyance driven roller holder 20 that pivotally supports the conveyance driven roller 22. The guide roller 23 is a roller for preventing the recording paper P from lifting from the platen 28, and thereby the distance between the recording paper P and the recording head 14 is kept constant.

  Next, a recording head 26 and a platen 28 are provided on the downstream side of the transport driving roller 21 so as to face each other. The recording head 26 is provided at the bottom of the carriage 25, and performs recording by ejecting (jetting) ink droplets as an example of a liquid toward the recording paper P. The carriage 25 is fixed to a part of an endless belt 24 (FIG. 3) extending in the main scanning direction, and is reciprocated in the main scanning direction while being guided by a guide plate 35 under the power of a carriage driving motor (not shown). .

  In the present embodiment, the carriage 25 does not have an ink cartridge mounted thereon, and ink is supplied from the ink cartridge 4 detachably provided on the bottom of the main body of the printer 1 to the recording head 26 via the ink tube 43 shown in FIG. Is configured to be supplied. The ink tube 43 is bundled with a plurality of flexible tubes corresponding to each color of a plurality of colors of ink (in this embodiment, 6: 2 horizontal x 3 vertical) by a binding tool not shown. The ink cartridge 4 provided at the bottom of the main body of the printer 1 and the recording head 26 communicate with each other.

  Here, the ink cartridge 4 according to the present embodiment is provided with an IC chip (not shown) that holds information about the ink cartridge 4 (variation information such as the remaining amount of ink and other fixed information). . On the other hand, a connecting portion (not shown) for connecting to the IC chip is provided on the apparatus main body 1a side (inside the ink cartridge housing chamber 6), and the control unit of the printer 1 uses the remaining ink amount stored in the IC chip. It is possible to acquire such information.

Returning to FIG. 4, the platen 28 defines the gap between the recording paper P and the recording head 25 by supporting the recording paper P from below, but a concave portion 28 a is formed on the surface facing the recording head 25. Is formed. This is for printing without margins on the recording paper P. When ink droplets are ejected to the edge of the recording paper P, ink droplets are ejected to the part off the recording paper P, Then, so-called borderless printing is performed by discarding into the concave portion 28a. An ink absorbing material 36 (FIG. 3) that absorbs ink droplets is disposed in the recess 28a.
The ink droplets discarded in the recess 28a are discharged downward from a discharge hole (not shown), and a waste liquid tray 31 for receiving the discharged ink droplets is provided below the platen 28. A waste liquid absorber 34 is provided inside the waste liquid tray 31 to reliably hold the ink waste liquid in the waste liquid tray 31.

  Subsequently, a discharge driving roller 29 and a discharge driven roller 30 are provided on the downstream side of the recording head 26. The discharge drive roller 29 is rotationally driven by a drive motor (not shown), and the discharge driven roller 30 is driven to rotate in contact with the discharge drive roller 29. The recording sheet P on which recording has been performed is discharged toward a stacker (not shown) by being nipped by these rollers. Further, a discharge auxiliary roller 37 is provided on the downstream side of the discharge drive roller 29, and the recording paper P that is nipped between the discharge drive roller 29 and the discharge driven roller 30 and discharged is further reliably discharged toward the stacker.

  Next, the ink supply system will be described. As shown in FIG. 3, a casing 45 that is long in the left-right direction of the printer 1 is provided at the front bottom of the apparatus main body of the printer 1, and an ink supply port (not shown) of the ink cartridge 4 is provided in the casing 45. Ink supply needles (not shown) are provided to be connected to each other, a plurality of ink flow paths (not shown) are formed, and the ink is guided to the left side of the apparatus, that is, to the valve device 40. . The valve device 40 opens and closes the ink flow path connecting the ink cartridge 4 and the recording head 26, and opens and closes the ink flow path when a swingable holder 41 swings. Configured.

  Two means are provided as means for swinging the holder 41, and the first means is a lever 39 that pushes the holder 41 from the side in conjunction with the attaching / detaching operation of the ink cartridge 4, and the ink cartridge 4 3 is in a state as shown in FIG. 3 (the state in which the holder 41 is not pushed: the state in which the holder 41 is standing substantially vertically). In this state, the ink flow path is opened. Then, when the ink cartridge 4 is removed from the state, the lever 39 pushes the holder 41 in the right direction in conjunction with this movement, so that the holder 41 swings so as to fall in the right direction. The road is closed.

  This is because, in the printer 1, the ink cartridge 4 is provided at the bottom of the apparatus, and therefore, if the ink cartridge 4 is removed, ink droplets leak due to the height difference from the recording head 26. Therefore, when the ink cartridge 4 is removed, the ink flow path is always closed by the first means. The holder 41 is urged by an urging means (not shown) so as to open the ink flow path (a state in which the ink channel stands substantially vertically).

  The second means is a rack and pinion mechanism 50 that is operated by the cooperative operation of the carriage 25 and the discharge driving roller 29 (paper feed motor). In general, the front side of the printer is operated by the operation of the rack and pinion mechanism 50. A lever (not shown) that advances toward (on the holder 41 side) abuts against the cam surface (not shown) formed on the holder 41 to push the holder 41 away, so that the holder 41 moves in the right direction. The ink flow path is closed by swinging so as to fall. This is mainly because the ink flow path is closed when the ink is sucked by generating a negative pressure in the cap by a pump means (not shown) with the recording head 26 being capped by a cap means (not shown). Operation for the purpose of increasing the bubble flow in the ink channel by generating a negative pressure in the ink channel in advance by performing the ink suction operation for a certain period of time and then opening the ink channel at once. It is for doing.

The above is the ink supply system, and the ink storage chamber for storing the ink cartridge 4 will be described below.
The ink cartridge 4 is accommodated in an ink cartridge accommodation chamber (hereinafter abbreviated as “accommodation chamber”) 6 that has an insertion port for the ink cartridge 4 and is disposed at the bottom of the printer 1. The storage chamber 6 is configured to include metal plate members disposed on both sides and above and below the ink cartridge 4 so as to carry the apparatus main body 1 a of the printer 1 and to surround the ink cartridge 4.

  That is, as shown in FIGS. 5 and 6, the storage chamber 6 is substantially U-shaped by side frames 61 and 62 disposed on both sides of the ink cartridge 4 and an intermediate frame 63 that covers the upper surface of the ink cartridge 4. The carrier is configured to have a shape, and includes a lower housing 54 and a reinforcing plate 65 disposed on the bottom surface of the ink cartridge 4.

  The carrier constituted by the side frames 61 and 62 and the intermediate frame 63 carries the apparatus main body 1a of the printer 1 and forms a space for accommodating the ink cartridge 4 by the above U-shape. The side frames 61 and 62 and the intermediate frame 63 are all made of a metal material, and can reliably resist the load received from the heavy apparatus main body 1a.

  The lower housing 54 is integrally formed of a resin material, and a plurality of ribs 54b and 54c are formed on the surface so as to resist the force that causes warping or deformation as shown in FIG. ing. In the lower housing 54, a guide portion 54a that forms a surface parallel to the front surface of the printer 1 and extends substantially vertically is formed on the front side of the printer 1, and the stacker 57 described with reference to FIG. It is designed to be pivotally supported below. Therefore, by forming the guide portion 54a, the front side of the lower housing 54 can further counteract forces that cause warping, deformation, and the like. In addition, a reinforcing plate 65 is attached on the rear side of the lower housing 54, that is, on the insertion port side of the ink cartridge 4, as a means for countering the force that causes the above-described warpage or deformation.

  Here, as the force that causes the lower housing 54 to be warped, deformed, or the like, a force received from the support leg 59 can be cited. That is, holes 54d for attaching the support legs 59 are formed in the vicinity of the four corners of the plate-shaped lower housing 54. Therefore, when the printer 1 is installed in the lower housing 54, the support legs 59 are interposed via the support legs 59. The load by the apparatus main body 1a acts, and this becomes a force which causes the lower housing 54 to warp or deform.

  The operation and effect of the housing portion 6 configured as described above will be described. First, the housing chamber 6 includes the apparatus main body 1a by a carrier composed of side frames 61 and 62 formed of a metal plate material and an intermediate frame 63. Since it is carried, the strength of the storage chamber 6 is ensured, and the storage space of the ink cartridge 4 can be secured over a long period of time. Further, as described above, since the ink cartridge 4 includes an IC chip that holds information such as the remaining amount of ink, the control unit of the printer 1 can manage the remaining amount of ink. However, it is necessary to ensure an electromagnetic wave shielding function from the request to exchange information accurately. However, since the storage chamber 6 is formed so as to surround the ink cartridge 4 by the metal plate as described above, it has good electromagnetic wave shielding properties. Therefore, even when the ink cartridge 4 is arranged at the bottom of the printer, a desired function can be obtained over a long period of time.

  Further, since the support leg 59 for supporting the printer 1 is attached to the lower side of the storage chamber 6, that is, the lower surface of the lower housing 54, the lower housing 54 may be deformed by receiving a load from the support leg 59. Since the reinforcing plate 65 formed of a metal plate material is disposed at the portion where the support leg 59 is attached, the load can be resisted, and the lower housing 54 can be prevented from warping or deforming for a long time. An insertion port (frontage) for the ink cartridge 4 can be secured.

  The reinforcing plate 65 is formed with a convex shape (drawing portion) extending in the width direction of the printer 1 as indicated by the reference numeral 65a, which makes it possible to more reliably resist the load. ing. Further, as shown in FIG. 7, the insertion port side (the back side of the printer) of the ink cartridge 4 is reinforced by the reinforcing plate 65, but the guide portion 54a is formed on the opposite side (the front side of the printer) as described above. As a result, the load applied to the lower housing 54 can be countered, and therefore the reinforcing plate 65 does not need to be disposed over the entire surface of the lower housing 54, so that the cost can be reduced. It has become.
