Here, for example, as shown in FIG. 11, during the movement of the carriage 6 in the direction B1 of the reciprocating movement direction B, an air flow W1 is generated on the rear side in the direction B1 of the reciprocating movement direction B. To do. As shown in FIG. 11, during the movement of the carriage 6 in the direction B <b> 1, along with the movement, the capturing portion 38 a on the rear side in the direction B <b> 1 of the frame-shaped portion 37 causes the mist capturing port 43 to Convection W2 is generated by the inflowing airflow W1. That is, the mist can be captured by the capturing portions 38a and 38b by moving the carriage 6.
And both the capture parts 38a and 38b of a present Example are provided with the cover part 20 in the one end side edge part 39 of the downstream of the conveyance direction A, and the other end side of the upstream of the conveyance direction A becomes an opening part. The opening serves as the mist outlet 40 captured by the capturing portions 38a and 38b. That is, the outlet 40 is provided on the side of the recovery unit 13 that faces the recovery port 16.

In other words, the recording apparatus 1 according to the present embodiment includes a recording head 7 that ejects ink onto a recording medium, a carriage 6 that can reciprocate in a reciprocating movement direction B, and ink ejected from the recording head 7. And a recovery unit 13 that recovers mist generated in response to the recovery from the recovery port 16. The carriage 6 has capturing portions 38 a and 38 b that capture mist generated when ink is ejected from the recording head 7 at both ends of the recording head 7 in the reciprocating direction B. The capturing portions 38a and 38b are provided with a mist capturing port 43 through which an airflow can flow as the carriage 6 reciprocates, an outlet 40 for the airflow, and the airflow flowing from the capturing port 43 in the direction of the outlet 40. And a lid portion 20 as a regulating portion that regulates toward the head, and the outlet 40 is provided at a position that can face the recovery port 16.
As described above, the carriage 6 has the capturing portions 38 a and 38 b that capture mist generated when the liquid is discharged from the discharge portion 7 at both ends of the discharge portion 7 in the reciprocating direction B. For this reason, the recording apparatus 1 according to the present embodiment is configured such that the ink mist generated when ink is ejected from the ejection unit 7 as the carriage 6 is reciprocated by the capturing units 38 a and 38 b provided on the carriage 6. Is configured to be captured immediately after occurrence.
Further, the capturing portions 38a and 38b have a mist capturing port 43 through which airflow can flow in along with the reciprocating movement of the carriage, an outlet 40 of the airflow, and the airflow flowing in from the capturing port 43 toward the outlet 40. The outlet 40 is provided at a position that can face the recovery port 16. For this reason, the recording apparatus 1 according to the present embodiment can move the mist that has flowed into the capturing units 38a and 38b to the collecting unit 11, and can also prevent the capturing units 38a and 38b themselves from being contaminated with mist and causing problems. It is configured.
The carriage 6 of this embodiment is configured to include the capturing units at both ends in the reciprocating direction B, but may be configured to include the capturing units on at least one side of the recording head 7 in the reciprocating direction B.

Further, as shown in FIGS. 8 to 11, the capturing portions 38a and 38b of the present embodiment are provided with a capturing port 43 on the side facing the recording medium. For this reason, since the mist can be captured from the side facing the recording medium on which a large amount of mist floats, the mist of the ink generated by ejecting the ink from the ejection unit 7 can be efficiently captured immediately after the occurrence. Can do.
Furthermore, since the capturing portions 38a and 38b of the present embodiment extend in the transport direction A, which is an intersecting direction that intersects the reciprocating direction B, it is possible to capture mist from a wide range in the transport direction A.
The capture port 43 of this embodiment is a rectangular opening along the transport direction A, and is configured as a continuous opening that is different from the outlet 40 only in the opening direction, but is limited to such a configuration. For example, the capture port 43 may have a configuration in which a plurality of holes are provided along the conveyance direction A, or the opening may be separated by providing a lid member in the boundary region between the capture port 43 and the outlet 40. Good.

  Further, the restricting portion of the present embodiment is the lid portion 20 as described above, and more specifically, is an airflow stopper provided on the side opposite to the outlet 40 in the capturing portions 38a and 38b. For this reason, the recording apparatus 1 of the present embodiment is configured such that the mist that has flowed into the capturing portions 38a and 38b can be moved to the collecting portion 13 by a restriction portion having a simple configuration. However, the configuration of the restricting unit is not limited to the configuration of the lid unit 20 as in the present embodiment as long as the inflowing mist can be moved to the collection unit 13, and for example, the capturing unit 38a and A structure that partially covers one end side end 39 of 38b, or a net-like or slit-like structure may be used to prevent the mist flowing into the capturing portions 38a and 38b from moving to the one end side end 39 side. Any structure that can promote movement toward the collection unit 13 may be used.

Next, the collection unit 13 of the recording apparatus 1 of this embodiment will be described.
Here, FIG. 15 is a schematic side cross-sectional view of the main part of the recording apparatus 1 of the present embodiment for explaining the positional relationship between the collection unit 13 of the present embodiment, the carriage 6 and the blower 12. FIG. 16 is a schematic perspective view showing the collection chamber 41 inside the collection unit 13.

As shown in FIG. 15, in the conveyance direction A, airflow can be blown toward the upstream side in the conveyance direction A on the downstream side of the movement area (corresponding to the recording area) in the reciprocation direction B of the carriage 6. An air blowing unit 12 is provided, and a recovery unit 13 is provided upstream of the moving region. By arranging the collection unit 13 in this way, the ink mist generated in the recording area can be collected efficiently.
Further, as illustrated in FIG. 15, the outlet 40 is disposed so as to face the recovery port 16 of the recovery unit 13. As shown in FIG. 11, the airflow W1 that has flowed into the capturing portions 38a and 38b from the capturing port 43 as the carriage 6 reciprocates causes convection W2 inside the capturing portions 38a and 38b. And since the exit 40 is provided in the upstream in the conveyance direction A of the capture parts 38a and 38b, and the cover part 20 as an airflow stopper is provided in the downstream, the inside of the capture parts 38a and 38b is shown in FIG. As a result, an air flow W3 toward the outlet 40 is generated.
With such a configuration, the recording apparatus 1 according to the present embodiment can capture the mist with the capturing units 38 a and 38 b and move the captured mist from the capturing units 38 a and 38 b to the recovery unit 13. Then, in the collection unit 13, an air flow W4 is generated as shown in FIG. 15 by the suction fan 15 shown in FIG. 5, and the outside of the recording apparatus 1 is passed through the duct 42 (see FIG. 16). The mist can be moved to.

In the recording apparatus 1 of the present embodiment, the wind speed of the air flow 3 from the inside of the capturing units 38a and 38b toward the outlet 40 is higher than the wind speed of the air flow W4 from the recovery port 16 to the inside of the recovery unit 13 by the suction fan 15. It has also been adjusted to be slower.
That is, the recording apparatus 1 according to the present embodiment uses the position of the recovery port 16 as a reference, and the air flow from the recovery port 16 to the inside of the recovery unit 13 rather than the wind speed of the air flow W3 from the outside of the recovery unit 13 to the recovery port 16. W4 wind speed is faster. For this reason, the recording apparatus 1 according to the present embodiment suppresses that the airflow W3 including mist does not enter the collection unit 13 by adjusting the airspeed of the airflow W3 to be slower than that of the airflow W4. doing.

  As shown in FIG. 15, the capturing portions 38 a and 38 b of the present embodiment are tapered on the upstream side in the transport direction A (the length in the height direction decreases toward the outlet 40). ) For this reason, the mist can be accurately blown toward the collection unit 13.

  Further, as described above, the recording apparatus 1 of the present embodiment includes the suction fan 15 as shown in FIG. 5, and the suction fan 15 is collected through the duct 42 shown in FIG. 41. In other words, the collection unit 13 includes a suction fan 15 as a suction unit that generates an air flow from the collection port 16 toward the inside of the collection unit 13. For this reason, the recording apparatus 1 of the present embodiment is configured to be able to suitably suppress the backflow of ink mist from the collection unit 13.

Further, as described above, since the recording apparatus 1 of the present embodiment includes the air blowing unit 12 that blows air toward the recovery port 16 from the outside of the recovery unit 13, the mist is efficiently guided to the recovery unit 13. It is configured to be able to.
Note that the air blowing unit 12 stops air blowing while the carriage 6 (recording head 7) is moving in the reciprocating direction B (during recording) under the control of the control unit 23. For this reason, it has the structure which can suppress that a shift | offset | difference arises in the discharge position of the ink discharged from the recording head 7 by the airflow which the ventilation part 12 generate | occur | produces.
Furthermore, in the recording apparatus 1 of the present embodiment, the air velocity of the air flow W4 that goes from the recovery port 16 to the inside of the recovery unit 13 is made faster than the wind speed of the air flow generated by the air blowing unit 12. For this reason, the recording apparatus 1 of the present embodiment suppresses that the airflow generated by the air blowing unit 12 including mist does not completely enter the recovery unit 13.

  Further, as described above, the recording apparatus 1 according to the present embodiment is configured such that the recording head 7 can eject ink while reciprocating in the reciprocating movement direction B, but the suction fan 15 is controlled by the control unit 23. The suction state can be taken both when the carriage 6 (recording head 7) is moving in the reciprocating direction B and when it is stopped. That is, the suction fan 15 can be always in a suction state. Even if an air flow is generated inside the collection unit 13 by the suction fan 15, there is no deviation in the ink ejection position. Therefore, the recording apparatus 1 of the present embodiment is configured so that the suction fan 15 is always in the suction state so that the recording head In this configuration, it is possible to suitably suppress the backflow of the ink mist from the collection unit 13 while suppressing the occurrence of deviation in the ejection position of the ink ejected from the nozzle 7.

  As shown in FIG. 15, the recovery unit 13 of the present embodiment has an upper surface on the base portion 46 as shown in FIG. 16 that constitutes each surface other than the constituent area and the upper surface of the recovery port 16. Although the recovery chamber 41 is formed by placing the pipe 11a to be configured, it is not limited to such a configuration.
