  By the way, in such a printer provided with a heating section for heating the recording medium, the recording medium to be heated is recorded on the recording medium without the temperature being lowered at the end pressed by the guide member. It is necessary to maintain a high temperature throughout the entire area (printing area). That is, by maintaining a high temperature, the liquid adhering to the recording medium can be uniformly dried evenly to the end of the printing area, and a high-quality image can be printed on the recording medium.

  However, in the conventional printer, no proposal has been made for a configuration for maintaining the temperature of the heated recording medium for the guide member. Therefore, in the conventional printer, the heat of the guide member is dissipated by being transmitted from the guide member to the support member, and the temperature of the printing area of the heated recording medium is suppressed by the guide member due to the heat dissipation of the guide member. There may be a case where it is lowered at the end where it is applied. As a result, there is a possibility that a difference occurs in the dry state of the liquid attached to the recording medium, resulting in uneven drying.

  Such a situation is not limited to an ink jet printer, but is generally common in recording apparatuses having a guide member that guides conveyance of a recording medium and a heating unit that heats the recording medium.

The heated portion has a larger amount of heat storage due to the heating than other portions of the guide member other than the heated portion.

  According to this configuration, since the heated portion of the guide member can be kept at a high temperature by a large amount of heat storage, the liquid adhering to the recording medium that is conveyed while being guided by the guide member is prevented from being unevenly dried. Can be dried.

  In the recording apparatus, the heating unit heats the recording medium by radiation of infrared rays, and the guide member has a radiation rate with respect to the infrared rays that the heated portion is larger than the other portions. preferable.

In the recording apparatus, it is preferable that the guide member has the radiation rate of the heated portion of 0.8 or more.
According to this configuration, it is possible to keep the temperature of the heated portion at or above the temperature at which the occurrence of uneven drying can be suppressed.

  In the recording apparatus, it is preferable that a heat conduction path in which an area of a cross section intersecting the transport direction is reduced is formed between the heated portion and the other portion in the guide member.

According to this configuration, the heat accumulated in the heated portion is hardly transmitted from the heated portion to other portions, so that the heated portion can be kept at a high temperature.

  Hereinafter, as an example of a recording apparatus, an image including characters and figures is recorded (printed) by ejecting ink, which is an example of liquid, from a liquid ejecting head, which is an example of a recording unit, on a sheet, which is an example of a recording medium. An embodiment of an ink jet printer that performs this will be described with reference to the drawings.

  As shown in FIG. 1, the printer 11 according to the present embodiment includes a support member 12 that supports a sheet S conveyed by the conveyance unit 13, and the sheet S supported by the support member 12 extends along the surface of the support member 12. As shown by the white arrow in FIG. 1, a guide member 20 that guides so as to be smoothly conveyed in the conveyance direction Y is provided. In addition, the printer 11 includes a liquid ejecting head 15 that ejects and attaches ink to the paper S from the side opposite to the support member 12 side, and a heating unit 30 that heats the ink attached to the paper S. Yes.

  The support member 12 is provided in the printer 11 so as to extend in the width direction X (the front and back direction in FIG. 1) intersecting the transport direction Y of the paper S. The guide member 20 is attached to the support member 12 and guides the conveyance of the paper S by pressing the end portion in the width direction X of the paper S toward the support member 12. The transport unit 13 includes transport roller pairs 13a and 13b, one of which is driven by a drive source (not shown), and rotates while sandwiching the paper S, thereby transporting the paper S along the surface of the support member 12. . In the present embodiment, the paper S is conveyed in a continuous paper state by being unwound from the roll paper RS wound in a roll state on the supply reel 14a. Then, after the ink ejected and adhered to the transported paper S from the liquid jet head 15 is dried and fixed, an image is printed on the paper S, and then the paper S is again rolled by the take-up reel 14b. It is wound up.

  The liquid ejecting head 15 is provided in a carriage 17 that can reciprocate by a driving source (not shown) while slidingly contacting guide shafts 16a and 16b extending along the width direction X of the sheet S to be conveyed. More specifically, the liquid ejecting head 15 is arranged on the lower side on the gravity direction −Z side in the vertical direction so that the nozzle forming surface 15 a on which the nozzle for ejecting ink is formed faces the support member 12. And is moved along the width direction X (also referred to as a main scanning direction) together with the carriage 17.

  A connection tube 18 as an example of a liquid supply channel capable of supplying ink to the carriage 17 is connected, and ink is supplied from the connection tube 18 to the liquid ejecting head 15 through an ink channel (not shown) provided in the carriage 17. Is supplied. An ink supply tube 18 a that can be deformed following the reciprocating carriage 17 is connected to the connection tube 18 through a connection portion 18 b attached to a part of the carriage 17. Therefore, for example, an ink tank as an example of a liquid storage unit (not shown) that stores ink is supplied to the connection tube 18 via the ink supply tube 18a, and the ink flows through the connection tube 18. ing.

  In the printer 11 having such a configuration, when the carriage 17 moves (reciprocates) in the width direction X of the paper S, ink is ejected from the liquid ejecting head 15 onto the paper S on the support member 12. At this time, a region where the ink ejected on the paper S adheres becomes a printing region. The heating unit 30 for heating and drying the ink adhering to the printing area is arranged on the printer 11 with a predetermined distance from the support member 12 in the antigravity direction + Z (upward) orthogonal to the nozzle forming surface 15a. The carriage 17 is reciprocally movable along the width direction X between the heating unit 30, the support member 12, and the guide member 20.

  In the present embodiment, the heating unit 30 includes an infrared heater 31 and a reflecting plate 32 that extend along the extending direction of the support member 12, that is, the width direction X of the paper S, and is indicated by a dashed line arrow in FIG. 1. Infrared rays are radiated as described above to heat the ink ejected from the liquid ejecting head 15 and attached to the print area of the paper S. In addition, a metal cover 19 as an example of a heat shielding member that blocks infrared rays radiated from the heating unit 30 is attached to the carriage 17 so as to be positioned between the carriage 17 and the heating unit 30.

  As shown in FIGS. 2 and 3, the guide member 20 is formed at the side end of at least one side of the support member 12 in the extending direction of the sheet S conveyed in the conveyance direction Y as indicated by a white arrow in the drawing. The end portion Sb in the width direction X is guided. In this embodiment, the guide member 20 has a symmetrical shape in the extending direction of the support member 12, that is, the width direction X of the paper S, and the two guide members 20 having the symmetrical shape are used. It is possible to guide the respective end portions Sb on both sides in the width direction X of S.

  In the present embodiment, the guide member 20 is a substantially rectangular metal plate member having a longitudinal direction in the transport direction Y, and the predetermined width portions on both sides in the extending direction of the support member 12 that is the short direction thereof. A pair of hook-shaped portions 22 are formed by half punching or bending so as to have a step of a predetermined height above the base portion 21 located at the center in the short direction. When the guide member 20 is attached to the support member 12, the base portion 21 comes into contact with the support member 12 (see FIG. 1), and the saddle-shaped portion 22 sandwiches the sheet S between the upper surface 12 c of the support member 12. Thus, the sheet S is conveyed while being guided while being pressed to the upper surface 12 c side of the support member 12. For this reason, the collar-shaped part 22 functions as a pressing member for the paper S.

  In addition, the leading end Sa of the paper S unwound from the roll shape smoothly enters between the upper surface 12c of the support member 12 and the bowl-shaped part 22 at the upstream end in the transport direction Y of the bowl-shaped part 22. Thus, an inclined portion 22a that rises toward the upstream side in the transport direction Y is provided.

  In addition, the guide member 20 has a structure capable of adjusting the position according to the position of the end portion Sb in the width direction X of the sheet S conveyed on the support member 12. That is, the guide member 20 is attached to the support member 12 so as to be movable in the width direction X.

  Specifically, a square hole 23 is formed in the guide member 20 at the approximate center in the transport direction at the base portion 21. Along with the formation of the square hole 23, a part of the member is bent substantially perpendicularly to the support member 12 side to form the upstream bent portion 21a (see FIG. 1). On the other hand, at the downstream end of the base portion 21 in the transport direction Y, a downstream bent portion 21b (see FIG. 1) is formed in which a part of the member is bent substantially perpendicularly to the support member 12 side. The upstream bent portion 21 a slides along the standing wall portion 12 a located on the downstream side of the groove portion 12 </ b> M formed along the extending direction in the support member 12, and the downstream bent portion 21 b is formed on the support member 12. It slides along the standing wall portion 12b located at the downstream end.

  In the present embodiment, the pair of eaves-shaped portions 22 of the guide member 20 are respectively formed with rectangular recesses 24 at substantially the same positions in the conveying direction Y as the square holes 23 provided in the base portion 21. In addition, a pair of knobs 28 formed by bending the members on both sides in the short direction upward are formed at the downstream end of the base part 21 in the conveyance direction Y, and the operator holds the knobs 28. The position of the guide member 20 can be adjusted by sliding the guide member 20 in the width direction X of the paper S by pinching and operating.

  The guide member 20 having such a shape has a heated portion HP that is heated together with the paper S by the heating unit 30 in the transport direction Y of the paper S. That is, in the guide member 20, the upstream side portion in the transport direction Y with respect to the pair of recesses 24 formed in the bowl-shaped portion 22 is an opposing region facing the liquid ejecting head 15 that reciprocates in the main scanning direction. The facing region is a heated portion HP that is heated by the heating unit 30. And in this to-be-heated part HP, the guide member 20 has a predetermined radiation rate with respect to infrared rays, and when the infrared rays radiated from the heating part 30 are absorbed, it is heated and the temperature rises.

  On the other hand, in the guide member 20, the downstream portion in the transport direction Y with respect to the pair of recesses 24 is transmitted by heat from, for example, the upstream bent portion 21 a and the downstream bent portion 21 b to the support member 12 in contact therewith. It is a heat radiating part that radiates heat. By this heat dissipation, the temperature rise of the knob 28 is suppressed, and the operator can adjust the position of the guide member 20 by holding the knob 28.

  As shown in FIG. 3, the guide member 20 according to the present embodiment includes a heated portion HP and other portions AP positioned downstream of the heated portion HP in the transport direction Y of the paper S. 23 and the pair of recesses 24 are connected by a connecting portion CP in which the total area of the cross section of the member intersecting the conveying direction Y is reduced.

  That is, as shown in FIG. 4, in the connecting portions CP, the plate thickness Ta of the guide member 20 is reduced to the plate thickness Tb in each recess 24. Further, the connecting portion CP is removed by a square hole 23 formed in the base portion 21. As a result, as shown by hatching in FIG. 4, the total area of the cross section of the member that intersects the transport direction Y decreases. In the present embodiment, the connecting portion CP is provided in a portion adjacent to the heated portion HP in the other portion AP of the guide member 20 and is a portion corresponding to the length of the concave portion 24 in the transport direction Y.

  The connecting portion CP is a heat conduction path from the heated portion HP to the other portion AP downstream in the transport direction Y in the guide member 20 and has a reduced cross-sectional area that intersects the transport direction. Function. Therefore, the heat of the heated part HP generated by heating by the heating unit 30 is suppressed by the reduction of the cross-sectional area from being transmitted from the heated part HP to the other part AP through the connecting part CP, and the heated part HP The heat storage amount of the heated portion HP is configured to be larger than the heat storage amount of the other portions AP of the other guide members 20.

With reference to FIG. 5, the operation of the printer 11 of the present embodiment will be described.
First, in the case of the guide member 20 in which the amount of heat stored in the heated part HP is small, the temperature of the heated part HP when heated by the heating unit 30 does not increase. For this reason, the temperature of the paper S when being conveyed while being guided by the guide member 20 is short in the width direction X from the paper edge (edge Sb) in the printing region, as indicated by a solid line in FIG. It is low at the position, that is, at the end of the printing area close to the guide member 20.

  On the other hand, in the case of the guide member 20 in which the heat storage amount of the heated part HP is large, the temperature of the heated part HP when heated by the heating unit 30 becomes high. As a result, the temperature of the sheet S when being conveyed while being guided by the guide member 20 is the end of the print area of the sheet S being pressed by the guide member 20 that has become hot, as shown by a thick broken line in FIG. The temperature is raised at the part to increase the temperature. As the temperature rises at the edge of the printing area, as shown by the thin broken line in FIG. 5, the sheet S is the average of the area facing the liquid ejecting head 15 to which ink is attached in the entire width direction X of the printing area. The temperature is raised so as to be approximately the same temperature.

According to the above embodiment, the following effects can be obtained.
(1) Since the heated portion HP of the guide member 20 can be kept at a high temperature by a large amount of heat storage, uneven drying of the ink adhering to the sheet S conveyed while being guided by such a guide member 20 is suppressed. It can be dried in the state.

  (2) In the guide member 20, a heat conduction path is formed between the heated portion and other portions in the transport direction of the paper S so that the cross-sectional area that intersects the transport direction decreases. Therefore, the heat accumulated in the heated part is hardly transmitted from the heated part to other parts, and thus the heated part can be kept at a high temperature.

  (3) Since the heated portion HP is an opposing region facing the liquid ejecting head 15 in the guide member 20, the ink ejected from the liquid ejecting head 15 on the paper S is immediately dried in a state where drying unevenness is suppressed. It is possible.

In addition, you may change the said embodiment into another embodiment as follows.
In the above-described embodiment, it is preferable that the guide member 20 has a radiation rate with respect to infrared rays of the heated portion HP of 0.8 or more.

May also be larger. For example, when the medium to be conveyed has a low value of the emissivity with respect to infrared rays such as a metal sheet, even if the emissivity with respect to the infrared rays of the heated portion HP is a value smaller than 0.8, There is no problem if the emissivity is larger than the emissivity of other parts.

According to this modification, in addition to the effects (1) to (3) of the above embodiment, the following effect (5) is obtained.

The cross-sectional area may be reduced by the rectangular hole 25. In this case, it is preferable that the sheet S is not engaged with the rectangular hole 25 and stopped when being conveyed below the rectangular hole 25. As an example, as shown in FIG. 7A, it is preferable that the rectangular hole 25 has a shape in which the hole width gradually decreases toward the conveyance direction Y side of the paper S.

  According to this configuration, similarly to the above-described embodiment, the heat accumulated in the heated part HP is not easily transmitted from the heated part HP to other parts, so that the heated part HP can be kept at a high temperature. is there.

The surface treatment layer 27 may be formed on the upper surface of the member facing the portion 30. Since the surface treatment layer 27 becomes the heated portion HP, the heat storage amount can be easily made larger than the other portions of the guide member 20 by forming the surface treatment layer 27 to have a large emissivity. it can.

  Of course, the surface treatment layer 27 may be processed so that the emissivity is 0.8 or more. Incidentally, in this modification, the guide member 20 is stainless steel, the surface treatment layer 27 is baked black paint, and the emissivity of the surface treatment layer 27 is 0.94. Of course, the surface treatment layer 27 may be formed by chemical treatment such as black alumite treatment if the guide member 20 is an aluminum material.
