  By the way, in the recording apparatus described in Patent Document 1, the transport path for transporting the recording medium from the upstream recording head side space to the downstream heating means side space is formed by a plate-like member having thermal conductivity. ing. Therefore, there is a possibility that heat from the heating means is transmitted to the recording head side through the plate-like member.

  The present invention has been made in view of the above problems, and its purpose is to record by suppressing the transfer of heat from the side provided with the heating means in the conveyance path to the side provided with the recording means. An object of the present invention is to provide a recording apparatus capable of suppressing the influence of heat on the means.

In order to achieve the above object, a recording apparatus according to the present invention records a plate-like conveyance path forming member having thermal conductivity that supports a recording medium conveyed along a conveyance path, and the recording medium. And a heating unit that heats the recording medium on at least one of the upstream side and the downstream side of the position where the recording unit is disposed in the transport path, and the transport path forming member includes: A first conveyance path forming member located on the side where the recording means is arranged in the conveyance path, and a second conveyance path forming member located on the side where the heating means is arranged , and the second The transport path forming member is provided on the downstream side of the transport path with respect to the first transport path forming member, and an end portion on the upstream side in the transport direction of the second transport path forming member extends along the transport direction. The first transport path forming member extending in the downstream direction of the transport direction of the first transport path forming member is inclined away from the transport path toward the front end side, and on the upstream side of the transport direction of the second transport path forming member The inclined end portion and the end portion on the downstream side in the transport direction of the first transport path forming member are arranged so as to overlap in the vertical direction .

  According to this configuration, heat is not directly transmitted from the second conveyance path forming member heated by the heating means to the first conveyance path forming member located on the side where the recording means is disposed. It is possible to suppress the transfer of heat from the heating unit to the recording unit side. Therefore, the influence of heat on the recording means can be suppressed.

Further , although a gap is formed between the first conveyance path forming member and the second conveyance path forming member divided in the middle of the conveyance path, the conveyance in the second conveyance path forming member facing the gap is formed. end of the upstream side is inclined obliquely away from the conveying path as the distal end side. For this reason, for example, when the transport path is along the horizontal direction, the leading end of the recording medium forms the second transport path even if the leading end of the recording medium in the middle of transport is directed downward in the vertical direction. The member is slid on an upwardly inclined slope at the inclined end on the upstream side in the transport direction of the member, and is transported on the second transport path forming member to the downstream side in the transport direction. Therefore, the recording medium can be smoothly conveyed without hooking the leading end of the recording medium into the gap between the first conveyance path forming member and the second conveyance path forming member. In addition, the inclined end of the second transport path forming member on the upstream side in the transport direction and the end of the first transport path forming member on the downstream side in the transport direction are arranged so as to overlap in the vertical direction. Therefore, the heat from the side where the heating means is disposed is suppressed from flowing through the gap to the opposite side of the conveyance path.

Transport A portion of the step corresponding to the region between the roller main body portions in the width direction of the recording medium overlaps with the inclined end portion on the upstream side in the transport direction of the second transport path forming member. It extends toward the side.

  According to this configuration, of the end portion on the downstream side in the conveyance direction of the first conveyance path forming member, the portion corresponding to the region between the roller main body portions in the conveyance means in the width direction of the recording medium is the second conveyance path. The forming member extends so as to overlap with an inclined end portion on the upstream side in the transport direction. Therefore, it can suppress that the warm air blown from the heating means passes through the area between the roller main body portions of the first roller and the second roller and flows into the area on the side where the recording means is arranged. .

  In the recording apparatus according to the aspect of the invention, the recording unit is disposed in a region on the opposite side of the surface of the transport path forming member on which the heating unit is disposed, and the heating unit in the recording medium is heated. Recording is performed on the surface opposite to the surface to which the wind is blown.

  According to this configuration, the heating unit and the recording unit are disposed in regions opposite to each other across the conveyance path forming member including the first conveyance path forming member and the second conveyance path forming member. Therefore, the influence of the heat of the heating unit on the recording unit can be suppressed.

In the recording apparatus of the present invention, the first transport path forming member and the second transport path forming member are each formed of stainless steel.
According to this configuration, since stainless steel has a low friction coefficient and high wear resistance, it can be smoothly transported even when a large amount of recording media is transported.

Then, as shown in FIG. 3A, the sheet S is conveyed toward the downstream side in the conveying direction in a state where the sheet S is sandwiched between the driven roller main body 42 and the driving roller main body 44. . In these respects, the driven roller 18b functions as a first roller that comes into contact with the surface of the sheet S (recording medium) on which recording is performed, and the drive roller 18a comes into contact with the driven roller 18b (first roller). It functions as a 2nd roller which contact | abuts the surface on the opposite side to the done surface. The third transport roller pair 18 functions as a transport unit that sandwiches and transports the sheet S (recording medium) between the driven roller 18b (first roller) and the drive roller 18a (second roller).

  As shown in FIGS. 2 and 3, the first guide plate 36 is formed in a substantially rectangular plate shape from stainless steel having thermal conductivity. Stainless steel has a low coefficient of friction and excellent wear resistance compared to other metals (for example, iron and aluminum). At the downstream end of the first guide plate 36 in the transport direction, a rectangular recess 36a along the transport direction X (left-right direction) is spaced in the width direction of the sheet S so that the end has a comb shape. Notches are formed at multiple positions. That is, at the downstream end of the first guide plate 36 in the transport direction, the driving roller main body 44 and the driven roller main body 44 and the driven roller main body 42 and the plurality of positions corresponding to the width direction of the sheet S are arranged at the plurality of positions. The same number of concave portions 36a as the main body portion 42 (six in this embodiment) are formed. In other words, at the end of the first guide plate 36 on the downstream side in the transport direction, a plurality of rectangular protrusions 36b in the width direction of the sheet S in the width direction of the sheet S in the transport direction X (downstream of the transport path). It is formed at a plurality of positions (seven locations in the present embodiment) avoiding the region where the portion 44 and the driven roller main body portion 42 are disposed. Then, as shown in FIG. 3B, these convex portions 36b are the second guide so as to divide the space between the drive roller shaft 43 and the driven roller shaft 41 of the third transport roller pair 18 in the vertical direction. It extends to a position approaching the plate 37.

  As shown in FIGS. 1 to 3, the second guide plate 37 is formed in a substantially rectangular plate shape by stainless steel, like the first guide plate 36. At the end of the second guide plate 37 on the third transport roller pair 18 side (that is, the end on the upstream side in the transport direction), there is an inclined portion 37a that is inclined downward in the vertical direction toward the upstream side (right side) in the transport direction. Is provided. The inclined portion 37a is inclined at an acute angle with respect to the convex portion 36b of the first guide plate 36 so as to be farther from the first guide plate 36 (that is, the transport path) toward the distal end side. And the convex part 36b of the 1st guide plate 36 and the inclination part 37a of the 2nd guide plate 37 are the half part of the conveyance direction upstream in this inclination part 37a, ie, the middle of the extending direction in the inclination part 37a. The tip side portion and the tip side portion of the convex portion 36b are arranged so as to overlap in the vertical direction.

Next, the operation of the printer 11 configured as described above will be described by focusing on the operation of the transport path forming member 31 in particular.
For example, when the recording process is started in the printer 11, the long sheet S is unwound from the paper feeding unit 13 wound in a roll shape, and is also transported by the transport device 14 from the upstream side to the downstream side in the transport direction. It is conveyed to. In addition, while the heater 33 of the drying device 32 generates heat, the blower fan 34 is driven to start blowing hot air.

  Subsequently, when the sheet S passes below the first recording head 25, ink is ejected from the first recording head 25 onto the surface of the sheet S, whereby recording is performed on the surface of the sheet S. . In addition, the sheet S having the ink attached to the surface is cut into single sheets of an arbitrary size by the cutter 26. Further, when the sheet S cut into a single sheet passes over the second recording head 29, the second recording head 29 presses the ink ribbon against the back surface of the sheet S, whereby the back surface of the sheet S is obtained. Is recorded. The sheet S on which recording has been performed by the second recording head 29 is conveyed further downstream, while the conveyance path forming member 31 is in sliding contact with the back surface (lower surface) side.

  Here, as shown in FIGS. 2 and 3, the conveyance path forming member 31 is divided into a first guide plate 36 and a second guide plate 37, so the first guide plate 36 and the second guide in the conveyance path. A gap is formed between the plate 37 and the tip of the sheet S that may be caught. However, an inclined portion 37 a that is inclined upward in the transport direction X is provided at the end of the second guide plate 37 on the upstream side in the transport direction. Therefore, even if the leading end in the transport direction of the sheet S being transported has a bent shape that faces downward in the vertical direction, the leading end of the sheet S slides on the inclined portion 37 a of the second guide plate 37. Then, it is transported on the second guide plate 37 downstream in the transport direction.

Further, since both the first guide plate 36 and the second guide plate 37 are made of stainless steel, there is little friction with respect to the sheet S and less wear due to the sheet S.
When the sheet S conveyed on the second guide plate 37 toward the downstream side in the conveying direction passes below the drying device 32, hot air is blown from the drying device 32 to the surface of the sheet S.

  At this time, in addition to the sheet S, the second guide plate 37 of the conveyance path forming member 31 disposed below the drying device 32 in the vertical direction is also heated by the hot air blown from the drying device 32. The heat applied to the second guide plate 37 is transmitted through the second guide plate 37 in all directions. However, the heat is not transmitted from the second guide plate 37 to the first guide plate 36. This is because, as shown in FIGS. 3A and 3B, the first guide plate 36 and the second guide plate 37 are divided and not in contact with each other. It is suppressed that the heat of the drying apparatus transmitted to the right side) is transmitted to the first guide plate 36. That is, heat from the drying device 32 is suppressed from being transmitted to the side where the first recording head 25 and the second recording head 29 are arranged in the transport path.

  As shown in FIGS. 2 and 3, the convex portion 36 b of the first guide plate 36 extends in the vertical direction in the space formed between the drive roller shaft 43 and the driven roller shaft 41 of the third transport roller pair 18. It extends toward the downstream side in the transport direction so as to be divided into two. And the front-end | tip part of the convex part 36b in the 1st guide plate 36 and the inclination part 37a of the 2nd guide plate 37 have overlapped in the up-down direction. That is, the first guide plate 36 and the second guide plate 37 suppress the formation of a gap space that connects the upper region and the lower region in the transport path in the vicinity of the third transport roller pair 18. Therefore, the second recording unit 28 is provided through the gap space where the heat of the drying device 32 communicates with the upper region and the lower region of the conveyance path formed in the third conveyance roller pair 18. It is suppressed that it flows into the area | region used as the lower side of a conveyance path | route.

The sheet S on which the ink on the surface has been dried by the drying device 32 is further conveyed, discharged from the discharge port 35 to the outside of the main body case 12, and stacked on the discharge unit 35a.
According to the above embodiment, the following effects can be obtained.

  (1) Heat is directly transferred from the second guide plate 37 heated by the drying device 32 to the first guide plate 36 located on the side where the first recording head 25 and the second recording head 29 are disposed. Therefore, heat from the drying device 32 can be prevented from being transmitted to the first recording head 25 and the second recording head 29 side. Therefore, the influence of heat on the first recording head 25 and the second recording head 29 can be suppressed.

  (2) Although a gap along the conveyance path is formed between the first guide plate 36 and the second guide plate 37 divided in the middle of the conveyance path, conveyance in the second guide plate 37 facing the gap is formed. The end on the upstream side in the direction is inclined at an acute angle so as to be farther from the transport path toward the tip side. Therefore, for example, when the conveyance path is along the horizontal direction, even if the leading end portion of the sheet S in the middle of conveyance is directed downward in the vertical direction, the leading end portion of the sheet S is on the second guide plate 37. The second guide plate 37 is transported downstream in the transport direction by sliding on the upward slope of the inclined portion 37a on the upstream side in the transport direction. Therefore, the sheet S can be smoothly conveyed without causing the leading end of the sheet S to be caught in the gap between the first guide plate 36 and the second guide plate 37.

  (3) The convex portion 36 b on the downstream side in the transport direction of the first guide plate 36 extends so as to overlap the inclined portion 37 a on the upstream side of the second guide plate 37 in the transport direction. Therefore, the warm air blown out from the drying device 32 passes through the region between the roller main body portions of the driving roller 18a and the driven roller 18b and flows into the region on the side where the second recording head 29 is disposed. Can be suppressed. Therefore, it is possible to suppress the influence of the heat of the drying device 32 on the second recording head 29 disposed in the opposite region across the drying device 32, the first guide plate 36, and the second guide plate 37.

  (4) Since stainless steel has a low coefficient of friction and high wear resistance, the sheet S can be smoothly conveyed even when a large amount of the sheet S is conveyed on the conveyance path forming member 31.

In addition, you may change the said embodiment as follows.
The sheet S is not limited to continuous paper but may be a continuous film, for example. Further, the sheet S may not be cut to an arbitrary length during the conveyance. Furthermore, the sheet S may be formed in a single sheet state from the beginning.

  In the case where the driving roller 18a and the driven roller 18b of the third conveying roller pair 18 have roller main body portions 42 and 44 extending over the entire width direction of the sheet S, the end portion on the downstream side in the conveying direction of the first guide plate 36 It is not necessary to provide the convex part 36b, and it is not necessary to provide the inclined part 37a at the end of the second guide plate 37 on the upstream side in the transport direction.

  The end of the first guide plate 36 on the downstream side in the transport direction and the end of the second guide plate 37 on the upstream side in the transport direction may not overlap in the vertical direction (vertical direction). However, in this case, both the guide plates 36 in the plan view, such as the end portion on the downstream side in the transport direction of the first guide plate 36 and the end portion on the upstream side in the transport direction of the second guide plate 37 are engaged in a comb shape. It is desirable that a wide gap is not formed between 37.

  The third conveyance roller pair 18 may not be provided between the first guide plate 36 and the second guide plate 37. However, in that case, the space area on the side where the drying device 32 is provided at the position between the first guide plate 36 and the second guide plate 37 in the transport direction X and the side where the recording heads 25 and 29 are provided. It is desirable to provide a partition member that partitions the space region.

  -Each roller main-body part 42 and 44 in the drive roller 18a in the 3rd conveyance roller pair 18 and the follower roller 18b is not restricted to what was divided | segmented into plurality in the axial direction of each roller axis | shaft 41 and 43, For example, on each roller axis | shaft The thing which makes the elongate cylinder extended along may be sufficient. Further, the driving roller 18a may be brought into contact with the surface (upper surface) of the sheet S. Further, the sheet S may be conveyed only by the driving roller 18a.

  The drying device 32 is not limited to one that blows hot air, but may be one that does not blow hot air, such as infrared rays, a halogen lamp, or a sheathed heater. Alternatively, the sheet S may be heated by contacting the sheet S.

The second recording head 29 may not be provided in a region on the opposite side across the drying device 32, the first guide plate 36, and the second guide plate 37 in the conveyance path.

May be. Further, the surface may be coated with, for example, chrome plating or anodized film of aluminum and aluminum alloy. Moreover, it may not be made of metal but may be formed of a different material having wear resistance such as glass.
