Japanese Patent Laid-Open No. 10-83059

  In the drying apparatus of Patent Document 1, the warm air is blown in the direction along the paper surface of the photographic paper. In this case, the blowing direction is compared with the upstream portion in the blowing direction close to the blowing fan. The downstream portion of the paper is difficult to dry, and in particular, when photographic paper having a wide paper width is dried, uneven drying occurs.

  It should be noted that not only a photographic drying apparatus but also a target having a large area is dried, and there is a problem that uneven drying occurs because it is difficult to uniformly send a gas having a sufficient wind speed over the entire surface. It was.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a recording apparatus capable of uniformly drying a target.

  In order to achieve the above object, the recording apparatus of the present invention comprises a recording means for applying a recording process by attaching a recording material to a target, and a gas used for drying the recording material attached to the target. First blowing means that blows out, and second blowing means that blows the gas blown from the first blowing means toward the recording surface on which the recording material adheres on the target by accelerating the wind speed of the gas. It was.

  According to this configuration, since the second air blowing unit that accelerates the wind speed of the gas blown from the first air blowing unit and blows the air toward the recording surface to which the recording material is attached on the target is provided, it is sufficient for the entire recording surface. It is possible to ensure a uniform wind speed and to dry the target uniformly.

  In the recording apparatus of the present invention, the second air blowing means is set so that the air blowing direction with respect to the recording surface of the target is a non-perpendicular direction with respect to the recording surface.

  According to this configuration, the second air blowing means is set so that the air blowing direction with respect to the recording surface of the target is a non-perpendicular direction with respect to the recording surface, so that the gas flows along the recording surface. Thereby, the fall of a wind speed can be suppressed.

  In the recording apparatus according to the aspect of the invention, the second air blowing unit may include a circulation air flow path that returns to the first air blowing unit side when the gas blown to the recording surface of the target flows along the recording surface. The gas blowing direction is set so as to form.

  According to this configuration, the second air blowing unit blows the gas so that a gas blown to the recording surface of the target flows along the recording surface to form a circulation air flow path that returns to the first air blowing unit side. Since the direction is set, the retention of gas can be suppressed and the gas can be circulated efficiently.

In the recording apparatus of the present invention, heating means for heating the gas is disposed in the middle of the circulating air passage.
According to this configuration, since the heating means for heating the gas is disposed in the middle of the circulation air passage, the heat efficiency can be improved by circulating the heated gas along the circulation air passage.

  In the recording apparatus according to the aspect of the invention, in the second air blowing unit, a plurality of axial fans that allow the gas blown from the first air blowing unit to pass in the axial direction are disposed adjacent to each other in a plane orthogonal to the axial direction. A cylindrical rectifying member extending along the axial direction is attached to each axial fan.

  According to this configuration, the second air blowing unit has a configuration in which a plurality of axial fans that allow the gas blown from the first air blowing unit to pass in the axial direction are arranged adjacent to each other in a plane orthogonal to the axial direction. Since each axial fan is provided with a cylindrical rectifying member extending in the axial direction, gas can be uniformly fed to the entire recording surface of the target.

  Hereinafter, an embodiment in which the recording apparatus of the present invention is embodied in a lateral type ink jet printer will be described with reference to FIGS. In the following description, when referring to “front-rear direction”, “left-right direction”, and “up-down direction”, the directions indicated by arrows in FIGS.

  As shown in FIG. 1, an ink jet printer 11 as a recording apparatus includes a cuboid body case 12. In the main body case 12, a feeding section 14 for feeding out the continuous paper 13 as a long target, a printing chamber 15 in which printing is performed on the continuous paper 13 by jetting ink as a recording material, and the printing A drying device 16 is provided as a drying means for performing a drying process on the continuous paper 13 to which the ink has adhered, and a winding unit 17 for winding the continuous paper 13 subjected to the drying process is provided.

  That is, a flat base 18 that divides the interior of the main body case 12 vertically is provided at a position slightly above the central portion in the vertical direction in the main body case 12, and is located above the base 18. This area is a printing chamber 15 in which a platen 19 having a rectangular plate shape is supported on a base 18. In the region below the base 18, the feeding portion 14 is disposed at the position on the left side on the upstream side in the conveyance direction of the continuous paper 13, and at the position on the right side on the downstream side. A drying device 16 and a winding unit 17 are provided.

  As shown in FIG. 1, a winding shaft 20 extending in the front-rear direction is rotatably provided in the feeding portion 14, and the winding shaft 20 is wound on the winding shaft 20 in a state where the continuous paper 13 is previously wound in a roll shape. And is supported so as to rotate together. In other words, the continuous paper 13 is fed from the feeding section 14 and conveyed downstream in the conveying direction when the winding shaft 20 rotates. Further, on the right side of the feeding unit 14, a first roller 21 that turns the continuous paper 13 fed from the winding shaft 20 from the lower right side to change the conveying direction of the continuous paper 13 vertically upward is wound. It is provided so as to extend in the front-rear direction in a manner parallel to the shaft 20.

  On the other hand, in the printing chamber 15, the second roller 22 is moved back and forth in a manner parallel to the lower first roller 21 at a position on the left side of the platen 19 and corresponding to the lower first roller 21 in the vertical direction. It is provided to extend in the direction. Then, the continuous paper 13 whose transport direction is converted to the vertically upward direction by the first roller 21 is wound around the second roller 22 from the lower left side, so that the transport direction is converted to the horizontal right direction, and the platen 19. It is designed to come into sliding contact with the upper surface.

  In the printing chamber 15, on the right side of the platen 19, a third roller 23 that faces the second roller 22 on the left side in the left-right direction across the platen 19 extends in the front-rear direction in a manner parallel to the second roller 22. It is provided as follows. The positions where the second roller 22 and the third roller 23 are installed are adjusted so that the tops of the peripheral surfaces are at the same height as the upper surface of the platen 19.

  Therefore, the continuous paper 13 whose conveyance direction is changed to the horizontal right direction by the left second roller 22 in the printing chamber 15 is conveyed to the right side which is the downstream side while being in sliding contact with the upper surface of the platen 19. By being wound on the roller 23 from the upper right side, the conveying direction is changed to a vertically downward direction and is conveyed toward the drying device 16 below the base 18. The continuous paper 13 that has been dried by passing through the drying device 16 is further conveyed vertically downward.

  Below the drying device 16, a continuous paper 13 that passes through the drying device 16 and is conveyed vertically downward is wound from above on the left side, so that the conveyance direction of the continuous paper 13 is converted into a horizontal right direction. Four rollers 24 are provided to extend in the front-rear direction, and a winding portion 17 is disposed on the right side of the fourth roller 24. The take-up unit 17 is provided with a take-up shaft 25 extending in the front-rear direction in a manner parallel to the fourth roller 24 so as to rotate based on the driving force of a conveyance motor (not shown). On the other hand, the leading end that is the downstream end in the conveyance direction of the continuous paper 13 is wound.

  Guide rails 26 (indicated by a two-dot chain line in FIG. 1) extending in the left-right direction are provided on both the front and rear sides of the platen 19 in the printing chamber 15 so as to form a pair. The upper surface of the guide rail 26 is higher than the upper surface of the platen 19, and a rectangular carriage 27 is formed on the upper surface of both guide rails 26 in the left-right direction along the both guide rails 26 based on driving of a drive mechanism (not shown). Are supported in a reciprocable state. A recording head 29 as recording means is supported on the lower surface side of the carriage 27 via a support plate 28.

  In the printing chamber 15, a certain range from the left end to the right end of the platen 19 is a printing area, and the continuous paper 13 is intermittently conveyed in units of the printing area. Then, ink is ejected from the recording head 29 along with the reciprocating movement of the carriage 27 to the continuous paper 13 which is stopped on the platen 19 by the intermittent conveyance in units of the printing area, and thereby the continuous paper 13 is ejected. Printing is applied. In the printing chamber 15, a maintenance mechanism 30 for performing maintenance of the recording head 29 at the time of non-printing is provided in a non-printing area on the right side of the third roller 23.

Next, the configuration of the drying device 16 will be described in detail.
As shown in FIG. 2, the drying device 16 has a housing 51 in which warm air for drying ink flows. The inside of the housing 51 is divided into a rear hot air generation chamber 53 (see FIG. 3) and a front drying chamber 54 (see FIG. 3) by a partition wall 52 extending in the left-right direction and the up-down direction. When the continuous paper 13 passes from the printing chamber 15 through the drying device 16 and is transported to the winding unit 17, the continuous paper 13 and the lower surface of the housing 51 (not shown) are provided in the upper surface 51 a of the housing 51. The recording surface 13a to which the ink is attached passes through the drying chamber 54 in a state where the recording surface 13a is directed to the right side. In addition, the dimension along the conveyance direction (vertical direction in FIG. 2) of the continuous paper 13 in the drying chamber 54 is set to a dimension corresponding to the horizontal length of the printing area that is an intermittent conveyance unit of the continuous paper 13. Along with intermittent printing and conveyance of the paper 13, a uniform drying time is ensured for each printing area.

  As shown in FIG. 3, a blower fan 55 is provided on the right side of the hot air generation chamber 53 as a first blower unit that blows out air that is a gas used for drying ink. In addition, a heater 57 as a heating means is provided on the left side of the blower fan 55 in the hot air generation chamber 53.

  When the blower fan 55 is driven, the air warmed by the heater 57 is sucked from the intake port 55a of the blower fan 55 through the path W1. And the warm air blown out from the blower opening 55b of the blower fan 55 is introduced into the drying chamber 54 through a path W2 passing through the vent hole 52a provided on the right end side of the partition wall 52. Yes. Further, on the left end side of the partition wall 52, a ventilation port 52b that allows passage of air between the drying chamber 54 and the hot air generation chamber 53 is provided.

  In addition, a lattice-like support frame 56 that extends substantially in the front-rear direction and the vertical direction is provided in the housing 51 so as to partition the drying chamber 54 into the left and right. The support frame 56 has a predetermined length portion on the front end side in a plan view serving as a support portion 56a for supporting an axial fan 58 described later, while a predetermined length portion on the rear end side in the plan view is a partition wall 52. It becomes the connection part 56b connected to.

  In other words, the connecting portion 56b of the support frame 56 has a length corresponding to the space in the front-rear direction between the partition wall 52 and the rear end side edge of the passage ports 51b, 51c in the right region from the passage ports 51b, 51c extending in the front-rear direction. It is comprised by the part which has thickness. The connecting portion 56b is located between the left and right ventilation ports 52a and 52b in the partition wall 52 so as to be parallel to the surface of the continuous paper 13 conveyed from above to below through the passage ports 51b and 51c. Connected to the position.

  On the other hand, the support portion 56a of the support frame 56 is also opposed to the paper surface of the continuous paper 13 at a predetermined angle α (0 ° <α <90 °) in the right region from the passage openings 51b and 51c. Are connected to the front end of the connecting portion 56b in a bent state. That is, the support portion 56a is disposed in an oblique state in plan view so that the front end portion is located on the left side that is the paper surface side of the continuous paper 13 rather than the rear end portion on the connection portion 56b side.

  The support portion 56a of the support frame 56 is formed with a plurality of through holes 56c arranged in the front-rear direction and the vertical direction (a total of 21 through holes in the front-rear direction and seven lines in the vertical direction). In each through hole 56c, an axial fan 58 as a second air blowing means is attached so as to protrude leftward. That is, the plurality of axial fans 58 are arranged adjacent to each other in a plane orthogonal to the axial direction of the rotation axis S, and the paper surface of the continuous paper 13 and the axial direction of the rotation axis S are non-orthogonal. It faces the recording surface 13a of the continuous paper 13 so as to form an angle α (0 ° <α <90 °).

  Further, a cylindrical rectifying member 58 a extending along the axial direction of the rotation axis S of each axial fan 58 is attached to the support portion 56 a of the support frame 56 so as to protrude rightward. Therefore, the warm air introduced into the drying chamber 54 from the warm air generating chamber 53 through the ventilation port 52a is uniformly guided into the through holes 56c through the path W3 by the rectifying member 58a. That is, the rectifying member 58 a is provided for each axial fan 58 so that the warm air is uniformly distributed to each axial fan 58.

  When each axial fan 58 is driven, warm air guided into each through hole 56c by the rectifying member 58a is blown onto the recording surface 13a of the continuous paper 13 through the path W4. That is, each axial flow fan 58 causes the warm air blown out from the blower fan 55 to pass through in the axial direction of the rotation axis S by accelerating the wind speed, so that the ink on the continuous paper 13 adheres to the recording surface 13a. It is designed to blow air toward it. Thereby, even when the area of the recording surface 13a is large, by adjusting the number and arrangement of the axial fans 58 according to the area, the entire recording surface 13a is uniformly blown and the drying process is performed without unevenness. Can do.

  In addition, since the blowing direction of each axial fan 58 is set to be a non-orthogonal direction with respect to the recording surface 13a, the warm air blown to the recording surface 13a is rearward along the recording surface 13a. The air flows toward the left end of the partition wall 52 and is returned to the warm air generating chamber 53 from the drying chamber 54 through the path W5 through the ventilation port 52b. In other words, when the air is blown in the direction orthogonal to the paper surface, the air velocity is reduced especially near the center of the paper surface and the wind speed is reduced. The air of sufficient wind speed can be sent to the entire recording surface 13a without being delayed.

  Moreover, since the blowing direction of each axial flow fan 58 is set so as to form a circulation blowing path that returns to the blowing fan 55 side, the circulation blowing paths W1 to W5 are formed in the casing 51, and the efficiency is improved. Air can be circulated. Then, the air recirculated into the warm air generating chamber 53 is again warmed by the heater 57, and is sucked from the intake port 55a of the blower fan 55 through the path W1. That is, since the heater 57 is arranged in the middle of the circulation air passage, the warm air is recirculated along the circulation air passages W1 to W5 so that the heat of the air is used without waste. It has become.

  In the housing 51, a partition plate 59 is provided on the back surface (surface opposite to the recording surface 13 a) side of the continuous paper 13 to which hot air is blown by the axial fan 58. The partition plate 59 is substantially L-shaped in plan view, and the rear end side is connected to the left side wall of the housing 51 and the front end side is connected to the front side wall 51 d of the housing 51. In the drying chamber 54, a space area 60 is enclosed by the partition plate 59 and the casing 51.

  The L-shaped crossing portion of the partition plate 59 in plan view is an inclined portion 59a that helps air flow back from the drying chamber 54 into the warm air generation chamber 53 through the path W5. A plurality of vent holes 59 b are formed in a portion extending in the left-right direction between the inclined portion 59 a and the left side wall of the housing 51. Further, a plurality of vent holes 51e are formed in the front side wall 51d of the casing 51 at a position in front of each vent hole 59b. Therefore, outside air (air) is supplied to the drying chamber 54 through the vent holes 59b and 51e. At this time, the inside of the drying chamber 54 and the space outside the housing 51 are communicated via the space 60 so as to suppress the influence of the incoming outside air on the air flow in the circulation air passage. It has become. Further, the air flowing in the space area 60 and the air in the drying chamber 54 are mixed, so that a temperature change accompanying the inflow of outside air is suppressed.

  Further, the vent holes 59b and 51e are located on the outer side of the drying chamber 54 where the flow velocity is slow and open to the lower side of the casing 51 as shown in FIG. Since it is provided, it has a structure in which high-temperature air accumulated above the drying chamber 54 is difficult to be discharged to the outside. Further, the air holes 59b are arranged adjacent to the path W5 through which the air whose humidity is increased and the temperature is decreased due to the volatilization of the ink flows along the recording surface 13a. Therefore, by replacing the so-called used air flowing through the path W5 through the vent hole 59b with fresh air (outside air), an increase in humidity in the drying chamber 54 is suppressed while considering thermal efficiency.

  By the way, the inside of the drying chamber 54 communicates with the external space area of the housing 51 through the passage openings 51b and 51c which are the entrances and exits of the continuous paper 13 in addition to the vent hole 51e. These passage openings 51b and 51c are inevitably provided in order to perform a drying process on the transport path of the continuous paper 13, but in particular, from the passage openings 51b provided on the upper surface 51a of the casing 51, Since air with a high temperature leaks out along the recording surface 13a, it is not preferable from the viewpoint of thermal efficiency. Further, when hot air blows out above the drying device 16, the hot air is applied to the recording head 29 that has moved toward the maintenance mechanism 30, or the temperature inside the printing chamber 15 is increased. In such a case, the nozzle opening of the recording head 29 may be dried, and the print quality may be adversely affected. Therefore, as a high-pressure chamber forming unit that forms a high-pressure space region having a higher pressure than that in the housing 51 at a position outside the passage 51 b on the upper surface 51 a (outer surface) of the housing 51 in which the passage 51 b is formed. The high-pressure space region forming apparatus 61 (see FIG. 2) is provided.

Next, the high-pressure space region forming device 61 will be described.
As shown in FIG. 2, the high-pressure space region forming device 61 includes a casing member 62 that partitions and forms a non-sealed space region at a position that is outside the passage port 51 b of the housing 51, and partition formation by the casing member 62. The sirocco fan 64 is provided as a blowing means for blowing air so that the pressure in the space area 63 (the high-pressure space area, see FIG. 4) is higher than the pressure in the housing 51. Note that the sirocco fan 64 sucks outside air and blows it out from the air blowing port 64a into the casing member 62, thereby drawing a gas (air) having a temperature lower than that of the warm air in the housing 51 in FIGS. It blows along the direction D (front direction) shown by the arrow.

  As shown in FIG. 4, on the upper surface 62 a of the casing member 62, a passage port 65 that serves as an inlet of the continuous paper 13 into the casing member 62 is provided at a position above the passage port 51 b. Further, a plate-shaped guide portion 66 is provided in the casing member 62 so as to connect the left side portions of the passage openings 65 and 51b. The back surface of the continuous paper 13 is guided by the guide portion 66 so that the continuous paper 13 passes through the casing member 62 while avoiding contact between the recording surface 13a to which the ink is attached and the passage port 65. . In FIG. 4, the sirocco fan 64 is not shown in order to clearly show the inside of the casing member 62.

  When the sirocco fan 64 is driven, the crossing direction (vertical direction) of the continuous paper 13 with respect to the passage port 51b extending in the front-rear direction is along the recording surface 13a to which the ink on the continuous paper 13 is attached. Air is blown into the space area 63 along the direction D (forward direction).

  Although the inside of the casing member 62 is in an unsealed state because it communicates with the outside through the passage port 65 and the inside of the housing 51 through the passage port 51b, the opening areas of the passage ports 65 and 51b are approximately the same. Are smaller than the blower port 64a of the sirocco fan 64 and the rear opening 67 of the casing member 62, which are connected to each other. Therefore, a high-pressure space area higher than atmospheric pressure is formed in the casing member 62. Is done. On the other hand, since the inside of the housing 51 communicates with the outside through the plurality of vent holes 51e in addition to the passage ports 51b and 51c, the inside thereof is kept equal to the atmospheric pressure. Therefore, the warm air flowing in the housing 51 is prevented from leaking through the passage port 51b due to the pressure difference between the housing 51 and the casing member 62.

  Further, on the right side of the guide portion 66 in the casing member 62, the air blown from the blower port 64a can be shielded at a position on the line connecting the passage port 51b of the casing 51 and the blower port 64a of the sirocco fan 64. A shielding member 68 is erected. Specifically, the shielding member 68 is about half the height of the casing member 62, and stands upward from the vicinity of the right side of the rear wall 68a and the passage port 51b, which stands upward from the rear end of the passage port 51b. It has an L-shape in plan view having a side wall 68b which is a mode to be provided. That is, since the air blown from the sirocco fan 64 is shielded by the rear wall 68a of the shielding member 68 provided on the rear side of the passage port 51b, the air blown from the sirocco fan 64 blows directly into the housing 51. There is no such thing. Therefore, it is possible to suppress the cold outside air sent from the sirocco fan 64 from flowing into the casing 51 to lower the thermal efficiency or to change the temperature distribution unevenly.

  Furthermore, since the front side is surrounded by the front side wall of the casing member 62, the left side is surrounded by the guide portion 66, and the right side is surrounded by the side wall 68 b of the shielding member 68, the sirocco fan 64 is located above the passage port 51 b. The flow rate of the sent air decreases. Thereby, the air sent from the sirocco fan 64 is further suppressed from flowing into the housing 51.

  On the other hand, since the shielding member 68 is about half the height of the casing member 62, in the lower region of the passage port 65 that is above the shielding member 68, the temperature that blows upward from the passage port 51b toward the passage port 65. The air flows along the direction D (forward direction) so as to prevent the flow of the wind. Thereby, it is suppressed that the warm air which flowed in from the inside of the housing | casing 51 in the casing member 62 leaks outside from the passage port 65 with high temperature. That is, the air leaking from the passage port 65 has a temperature closer to the outside air than the warm air in the casing 51, so that even if it flows into the printing chamber 15, a large temperature rise is not caused.

  Further, while the warm air leaking from the passage port 51b flows upward along the recording surface 13a, the sirocco fan 64 blows forward, so that the air leaking from the passage port 65 is directed diagonally forward. Flowing. Accordingly, the air leaking from the high-pressure space forming device 61 flows into the printing chamber 15 through the insertion hole formed in the base 18 so as to allow the continuous paper 13 to pass under the third roller 23. Is suppressed.

According to the embodiment described above, the following effects can be obtained.
(1) Since the axial flow fan 58 that accelerates the air velocity of the air blown from the blower fan 55 and blows air toward the recording surface 13a to which the ink on the continuous paper 13 is attached is provided, sufficient for the entire recording surface 13a. The continuous speed 13 can be uniformly dried while ensuring the wind speed.

  (2) Since the axial flow fan 58 is set so that the air blowing direction with respect to the recording surface 13a in the continuous paper 13 is a non-perpendicular direction with respect to the recording surface 13a, the air flows along the recording surface 13a. By making it flow, a decrease in wind speed can be suppressed.

  (3) The axial flow fan 58 blows air so as to form a circulation blowing path that returns to the blower fan 55 side when the air blown to the recording surface 13a of the continuous paper 13 flows along the recording surface 13a. Since the direction is set, the retention of air can be suppressed and the air can be circulated efficiently.

  (4) Since the heater 57 that heats the air is disposed in the middle of the circulation air passage, the heat efficiency can be improved by circulating the heated air along the circulation air passage.

  (5) A plurality of axial fans 58 that allow the air blown from the blower fan 55 to pass in the axial direction are arranged adjacent to each other in a plane orthogonal to the axial direction, and each axial fan 58 extends in the axial direction. Since the flow straightening member 58a is attached, air can be sent uniformly to the entire recording surface 13a.

  (6) Since a high pressure space region forming device 61 that forms a space region 63 having a pressure higher than the pressure in the housing 51 is provided at a position outside the passage port 51 b of the housing 51 in the drying device 16. Due to the pressure difference, it is possible to prevent the warm air for drying the ink adhering to the continuous paper 13 from leaking out from the passage port 51 b formed in the housing 51.

  (7) The high-pressure space region forming device 61 includes a casing member 62 that partitions and forms a non-sealed space region at a position outside the passage port 51b of the housing 51, and the pressure in the space region is changed to air in the casing member 62. Since the sirocco fan 64 that blows air so as to be higher than the pressure in the housing 51 is provided, a high-pressure space region can be formed with a simple configuration.

  (8) Since the sirocco fan 64 blows air having a temperature lower than that of the hot air, it is possible to suppress an influence such as a temperature rise caused by the leaked hot air. That is, even when the movement path of the printing chamber 15 and the recording head 29 is arranged above the drying device 16, the temperature rise in the printing chamber 15 and the drying of the nozzle openings of the recording head 29 can be suppressed.

  (9) The sirocco fan 64 blows air in the direction in which the continuous paper 13 passes with respect to the passage port 51b of the casing 51, that is, in the direction intersecting with the direction in which the leaking hot air flows. Can hinder. Further, since the sirocco fan 64 blows air in the direction along the recording surface 13a to which the ink on the continuous paper 13 adheres, the air can be effectively fed into the casing member 62 without being blocked by the continuous paper 13. . Furthermore, by blowing air in the direction along the recording surface 13a to which the ink is attached, drying of the ink attached to the continuous paper 13 can be promoted. (10) The high-pressure space region forming device 61 has a shielding member 68 capable of shielding the air blown from the blower port 64a at a position on the line connecting the passage port 51b and the blower port 64a of the sirocco fan 64. Therefore, it is possible to suppress the air sent by the sirocco fan 64 from flowing into the housing 51 from the passage port 51b.

  (11) Since the sirocco fan 64 blows outside air, air can be easily secured. Moreover, the temperature rise resulting from the leaked warm air can be suppressed by blowing outside air having a temperature lower than that of the warm air.

In addition, you may change each said embodiment into another embodiment as follows.
The height of the shielding member 68 can be an arbitrary height that is not limited to about half of the casing member 62. Furthermore, for example, the rear wall 68a may be higher than the side wall 68b, or the shielding member 68 may not be provided.

-The guide part 66 does not need to be provided in the casing member 62.
In the high-pressure space formation device 61, a fan other than the sirocco fan 64 may be used as the air blowing means, or a plurality of air blowing means may be provided.

  A passage opening may be formed on the side surface of the casing 51, and a high-pressure space region forming unit may be provided at a position on the side of the passage opening. Or you may make it provide a high voltage | pressure space area formation means in the position used as the outer side of the passage port 51c provided in the lower surface of the housing | casing 51. FIG.

  A small amount of water vapor, that is, dry air may be sent from the blower fan 55 and the sirocco fan 64. Thereby, drying of the ink can be further promoted.

  The number, arrangement, type, and the like of the axial fan 58 in the vertical direction and the front-rear direction can be arbitrarily set. For example, a blowing means having higher ability than the rear side may be arranged on the front side, or the number of installations may be increased.

  Each axial fan 58 may be arranged so that the recording surface 13 a of the continuous paper 13 and the axial direction of the rotation axis S of each axial fan 58 are orthogonal to each other. Or you may set the axial direction of the rotating shaft S of each axial flow fan 58 to the angle which does not form a circulation ventilation path | route. In this case, an increase in humidity in the drying chamber 54 can be suppressed by discharging the air whose humidity has increased due to the volatilization of the ink to the outside of the casing 51 without circulating it.

The rectifying member 58a may have a cylindrical shape or a rectangular tube shape having a polygonal cross section. Further, the rectifying member 58a may not be provided.
-Instead of the continuous paper 13, a long plastic film or cloth may be used as a target.

  In the above-described embodiment, the recording apparatus is embodied as an ink jet printer. However, the present invention is not limited to this, and liquids other than ink (a liquid material in which particles of a functional material are dispersed or mixed in a liquid, such as a gel) It can also be embodied in a liquid ejecting apparatus that ejects or ejects (including a fluid). For example, a liquid that ejects a liquid (liquid material) that is dispersed or dissolved in a material such as an electrode material or a color material (pixel material) used for manufacturing a liquid crystal display, an EL (electroluminescence) display, and a surface emitting display. The liquid ejecting apparatus may be a liquid ejecting apparatus that ejects a bio-organic matter used for biochip manufacturing, or a liquid ejecting apparatus that ejects a liquid that is used as a precision pipette and serves as a sample. In addition, transparent resin liquids such as UV curable resin to form liquid injection devices that pinpoint lubricant oil onto precision machines such as watches and cameras, and micro hemispherical lenses (optical lenses) used in optical communication elements. A liquid ejecting apparatus that ejects a liquid onto the substrate, a liquid ejecting apparatus that ejects an etching solution such as acid or alkali to etch the substrate, and a liquid ejecting that ejects a liquid (fluid) such as a gel (eg, physical gel) It may be a device. The present invention can be applied to any one of these liquid ejecting apparatuses.
