Description

Technical Field

[0001] The present invention relates to a recording apparatus such as a printer and a recording method.

Background Art

[0002] As an example of the prior art of this type of apparatus, the one described in Patent Document 1 can be cited. When printing directly on a fabric, stretching and shrinking are likely to occur, and the fabric is likely to deform. As a means for suppressing the stretching and shrinking, there is a method of attaching the fabric to an adhesive sheet and then printing. However, when the user himself / herself performs the operation of attaching the fabric to the adhesive sheet, there is variation in the pressing force applied by the user, and it is difficult to always obtain a prescribed attaching force. Patent Document 1 discloses an image forming apparatus provided with an attaching means for attaching a printing substrate (film) fed from a roll to the adhesive surface of a support substrate (film) fed from a roll-shaped feed roll to form a composite substrate.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Due to the compatibility between the adhesive on the adhesive surface and the fabric, there is a difference in the prescribed attaching force. Therefore, it is necessary to adjust the pressing force by the attaching means according to the type of the adhesive and the type of the fabric. However, in Patent Document 1 above, no consideration is given to the adjustment of the pressing force. If the fabric is pressed with a force less than the specified adhesive force, the fabric may peel off the adhesive sheet when it passes through the bending path or the transport roller, or when ink is ejected onto the fabric for printing, resulting in a printing failure. Conversely, if the fabric is pressed with a force greater than the specified adhesive force, excessive stress may be placed on the fabric when it is peeled off the adhesive sheet, potentially causing damage to the fabric. [Means for solving the problem]

[0005] To solve the above problems, the recording device according to the present invention is characterized by comprising: an unwinding unit that unwinds a roll-shaped medium, which has a cloth attached to a support member having an adhesive surface, in the transport direction; a recording unit that records on the medium; a pressing unit located upstream of the recording unit in the transport direction and gripping and pressing the medium; and an adjustment unit that can adjust the pressing force applied to the medium by the pressing unit.

[0006] Furthermore, the recording method according to the present invention is characterized by feeding out a roll-shaped medium, which has a cloth attached to a support member having an adhesive surface, in the transport direction, gripping and pressing the fed-out medium with a pressing unit, adjusting the pressing force applied to the medium by the pressing unit according to the type of medium, and recording on the medium by a recording unit at a position downstream of the pressing unit in the transport direction.

[0008] The present invention will now be described in general terms. To solve the above problems, a recording device according to a first aspect of the present invention is characterized by comprising: a dispensing unit that feeds out a roll-shaped medium, which has a fabric attached to a support member having an adhesive surface, in the transport direction; a recording unit that records on the medium; a pressing unit located upstream of the recording unit in the transport direction and gripping and pressing the medium; and an adjustment unit that can adjust the pressing force applied to the medium by the pressing unit.

[0009] According to this embodiment, the pressing unit is located upstream of the recording unit in the transport direction, and the pressing unit grips and presses the medium. Furthermore, an adjustment unit is provided that allows adjustment of the pressing force applied to the medium by the pressing unit. By adjusting the pressing force, it becomes easier to attach the fabric to the support member with a specified adhesive force, regardless of the type of fabric or adhesive on the adhesive surface. Therefore, the risk of the fabric peeling off the support member during transport of the medium or during recording by the recording unit is reduced. In addition, damage to the fabric that occurs when peeling the fabric off the support member can be suppressed.

[0010] A recording device according to a second aspect of the present invention is an aspect dependent on the first aspect, wherein the pressing section has a drive roller connected to a drive section and to which rotational driving force is applied, and a pressing roller that rotates in conjunction with the rotation of the drive roller, and the adjustment section has a spring connected to the pressing roller and a cam for adjusting the length of the spring.

[0011] According to this embodiment, the pressing unit includes a drive roller connected to a drive unit and to which rotational driving force is applied, and a pressing roller that rotates in conjunction with the rotation of the drive roller. The adjustment unit also includes a spring connected to the pressing roller and a cam for adjusting the length of the spring. This allows the adjustment of the pressing force by the adjustment unit to be achieved with a simple structure.

[0012] A recording device according to a third aspect of the present invention is an aspect dependent on the second aspect, characterized in that an elastic member is provided on the surface of the pressing roller.

[0013] According to this embodiment, an elastic member is provided on the surface of the pressing roller. This allows the elastic member to absorb the effects of deflection of the drive roller and small irregularities on the surface, thereby enabling an appropriate pressing force to be applied to the medium.

[0014] A recording device according to a fourth aspect of the present invention is an aspect dependent on the second aspect, wherein the pressing roller comprises a group of first rollers divided in a width direction intersecting the conveying direction of the medium, and a group of second rollers arranged downstream of the group of first rollers in the conveying direction and to fill the gaps between the first rollers in the width direction, and the spring and the cam are connected to the group of first rollers and the group of second rollers, respectively.

[0015] If the aforementioned pressure roller is constructed using only one roller, the roller diameter will need to be increased to absorb the deflection of the shaft, which may result in a larger overall size. According to this aspect, the pressing roller includes a group of a plurality of first rollers divided in the width direction intersecting the conveyance direction of the medium, and a group of second rollers disposed downstream of the group of the first rollers in the conveyance direction and arranged to fill the gaps between the first rollers in the width direction. That is, the pressing roller is divided into the group of the first rollers and the group of the second rollers. Further, the spring and the cam are connected to each of the group of the first rollers and the group of the second rollers. Thereby, it is not necessary to increase the roller diameter, and thus the enlargement can be suppressed.

[0016] The recording apparatus according to the fifth aspect of the present invention is an aspect dependent on the first aspect, and includes a conveyance roller that is disposed downstream of the pressing portion in the conveyance direction and conveys a medium. The pressing portion includes a driving roller that is connected to a driving unit and is given a rotational driving force, and a pressing roller that is driven to rotate passively in accordance with the movement of the medium sandwiched in pair with the driving roller. The adjustment unit adjusts the pressing force by rotating the driving roller in a reverse conveyance direction that is opposite to the conveyance direction.

[0017] According to this aspect, a conveyance roller for conveying the medium is provided downstream of the pressing portion. The pressing portion includes a driving roller that is connected to a driving unit and is given a rotational driving force, and a pressing roller that is driven to rotate passively in accordance with the movement of the medium sandwiched in pair with the driving roller. Further, the adjustment unit adjusts the pressing force by rotating the driving roller in a reverse conveyance direction that is opposite to the conveyance direction. Thereby, since the medium is in a state of receiving a force from the driving roller in a direction opposite to the conveyance direction while receiving a conveyance force in the conveyance direction from the conveyance roller, it becomes possible to efficiently increase the pressing force. And the pressing force can be adjusted by changing the rotational speed of the driving roller in the reverse conveyance direction.

[0018] The recording apparatus according to the sixth aspect of the present invention is an aspect dependent on the fifth aspect, characterized in that an elastic member is provided on the surface of the drive roller, and a low-friction material is provided on the surface of the elastic member.

[0019] According to this aspect, an elastic member is provided on the surface of the drive roller, and a low-friction material is provided on the surface of the elastic member. The surface of the drive roller is elastically deformed and presses the medium in a form that causes it to be crushed, so that it makes surface contact with the medium rather than line contact. As a result, the medium receives a force directed in the opposite direction to the conveyance direction from the drive roller and is in a rubbing state, but the pressing force can be adjusted in a state where damage to the medium is suppressed by the elastic member and the low-friction material.

[0020] The recording apparatus according to the seventh aspect of the present invention is an aspect dependent on the fifth aspect, characterized in that the rotational speed of the drive roller is greater than the rotational speed of the conveyance roller. Note that this aspect can also be made dependent on the sixth aspect.

[0021] According to this aspect, the rotational speed of the drive roller is set to be greater than the rotational speed of the conveyance roller. Thereby, the adjustment of the pressing force can be performed efficiently.

[0022] The recording apparatus according to the eighth aspect of the present invention is an aspect dependent on the fifth aspect, characterized in that the diameter of the drive roller is larger than the diameter of the conveyance roller. Note that this aspect can also be made dependent on the sixth aspect or the seventh aspect.

[0023] According to this aspect, the diameter of the drive roller is larger than the diameter of the conveyance roller. Thereby, due to the larger diameter, the contact area with respect to the medium can be ensured, and the pressing force can be applied efficiently.

[0024] A recording method according to a ninth aspect of the present invention is characterized by feeding out a roll-shaped medium, which has a cloth attached to a support member having an adhesive surface, in the transport direction; gripping and pressing the fed-out medium with a pressing unit; adjusting the pressing force applied to the medium by the pressing unit according to the type of medium; and recording on the medium by a recording unit at a position downstream of the pressing unit in the transport direction. According to this embodiment, the same effects as those of the first embodiment can be obtained.

[0025] [Embodiment] Hereinafter, a recording device and recording method according to embodiments of the present invention will be specifically described with reference to Figures 1 to 8. In this description, the case in which the recording device is an inkjet printer will be explained. In the following explanation, the three mutually orthogonal axes will be referred to as the X-axis, Y-axis, and Z-axis, as shown in each figure. The direction indicated by the arrows on the three axes (X, Y, Z) is the positive direction, and the opposite direction is the negative direction. The Z-axis direction corresponds to the vertical direction, i.e., the direction in which gravity acts, with the +Z direction indicating vertically upwards and the -Z direction indicating vertically downwards. The X-axis and Y-axis directions correspond to the horizontal direction. The +Y direction indicates the front direction of the recording device, and the -Y direction indicates the rear direction of the recording device. The +X direction indicates the right direction of the recording device, and the -X direction indicates the left direction of the recording device.

[0026] [Embodiment 1] The recording device 1 in this embodiment is an inkjet printer, as an example. As shown in Figure 1, the recording device 1 includes a dispensing unit 3 that feeds out the medium 2 in the transport direction F, a recording unit 4, a pressing unit 5, and an adjustment unit 6. The medium 2 is a roll-shaped medium in which a sheet-like fabric 9 is attached to a sheet-like support member 8 having an adhesive surface 7. The medium 2 is set in the dispensing unit 3 in the form of a roll R1. The dispensing unit 3 rotates the roll R1 to unwind the medium 2 in the transport direction F. The recording unit 4 performs recording by ejecting ink onto the fabric 9 of the unwound medium 2 in the recording execution area 10. In the recording execution area 10, the medium 2 is supported by a platen 11. The pressing unit 5 is located upstream of the recording unit 4 in the transport direction F. The pressing unit 5 is configured to grip the medium 2 moving in the transport direction F and apply a pressing force P to press it. The adjustment unit 6 is configured to adjust the pressing force P applied to the medium 2 by the pressing unit 5. The specific structures of the pressing unit 5 and the adjustment unit 6 will be described later.

[0027] As shown in Figure 1, the recording device 1 further includes a transport unit 12 that applies a transport force to the medium 2 toward the recording unit 4, intermediate rollers 13 and 14, a drying unit 15, an end roller pair 16, a fabric winding unit 17, and a support member winding unit 18. The transport unit 12 consists of a transport roller 121 that rotates after receiving power from a drive source, and a pressing roller 122 that rotates in conjunction with the rotation of the transport roller 121. The intermediate rollers 13 and 14 are positioned to change the transport direction of the medium 2 and rotate in conjunction with the movement of the medium 2 in the transport direction F. The drying unit 15 heats and dries the medium 2 from which the ink has been ejected. The end roller 16 grips the medium 2 and rotates in conjunction with the aforementioned movement of the medium 2. The fabric winding section 17 winds up only the fabric 8 to create a roll R2. The support member winding section 18 is positioned at a distance from the fabric winding section 17 and winds up only the support member 9 to create a roll R3. In other words, the medium 2 is held between the end rollers 16, and the fabric winding section 17 winds up only the fabric, while the support member winding section 18 winds up only the support member 9, so that the two are separated.

[0028] <Pressing part and adjustment part> Next, the structure of the pressing section 5 and the adjustment section 6 of the recording device 1 according to Embodiment 1 will be described with reference to Figures 1 to 3. The pressing section 5 consists of a pair of drive rollers 20 and pressing rollers 21. The drive roller 20 is power-connected to the drive unit 19 (Figure 1) and is provided with rotational driving force. A motor is used for the drive unit 20. The drive roller 20 is integrally mounted on the rotating shaft 25. Both ends of the rotating shaft 25 are rotatably supported by structural members such as a frame (not shown). The drive roller 20 rotates integrally with the rotating shaft 25 as the rotating shaft 25 rotates around its axis due to the rotational driving force of the drive unit 19. In Figure 3, the rotation axis 25 is omitted from the illustration to avoid complicating the drawing.

[0029] The pressure roller 21 rotates in conjunction with the rotation of the drive roller 20. The pressure roller 21 is rotatably mounted on the support shaft 26. That is, the pressure roller 21 is configured to rotate relative to the support shaft 26 in accordance with the rotation of the drive roller 20. In other words, the pressure roller 21 rotates in accordance with the movement of the medium 2, which is gripped by the pair with the drive roller 20, as it receives the conveying force from the rotation of the drive roller 20 and moves in the conveying direction F. In this embodiment, the release cam 27 is in contact with the support shaft 26. When setting the medium 2 between the drive roller 20 and the pressure roller 21, the distance between the drive roller 20 and the pressure roller 21 can be widened by rotating the release cam 27. In this embodiment, an elastic member 24 is provided on the surface of the pressure roller 21. The elastic member 24 is made of rubber.

[0030] In this embodiment, the adjustment unit 6 includes a spring 22 connected to the pressure roller 21 and a cam 23 for adjusting the length of the spring 22. Specifically, as shown in Figure 3, one end of the spring 22 is fixed to the support shaft 26 of the pressure roller 21, and the other end is fixed to the cam 23. The spring 22 is provided in a tension spring state and is configured to pull the pressure roller 21 toward the drive roller 20, thereby applying a pressing force P to the medium 2. The length of the spring 22 changes as the cam 23 rotates, that is, the pulling force changes, and this is configured to allow the magnitude of the pressing force P to be continuously changed and adjusted. Both ends of the support shaft 26 are supported by structural members such as frames (not shown) so as to be movable in a direction that allows the pressing force P to be increased or decreased, in order to allow adjustment of the pressing force P.

[0031] In this embodiment, the appropriate pressing force P is determined in advance through prototyping or other means for multiple types of media 2 that are expected to be used. The system is configured such that when the user identifies the type of media 2 via an operation panel (not shown in the figure), the cam 23 rotates and the corresponding pressing force P acts on the media 2. For new media 2 that are not intended for use, the system is configured so that the user can experiment or change the rotation state of the cam 23 based on experience to apply an appropriate pressing force to the media 2. In other words, the pressing force P applied to the medium 2 by the pressing part 5 can be adjusted according to the type of medium 2.

[0032] The operations of the dispensing unit 3, pressing unit 5, transport unit 12, recording unit 4, drying processing unit 15, fabric winding unit 17, and support member winding unit 18 are performed by the control unit 28 (Figure 1). Here, the control unit 28 is equipped with a CPU, flash ROM, and RAM. The CPU performs various calculations according to the program stored in the flash ROM and controls the operation of the entire recording device 1. Flash ROM, an example of a storage means, is a non-volatile memory that can be read and written to. RAM, another example of a storage means, temporarily stores various types of information.

[0033] <Adjusting the dispensing force and pressing force, and recording the data> In this embodiment, recording is performed by the recording unit 4 on the medium 2 dispensed from the dispensing unit 3, as described below. First, the dispensing unit 3 dispenses a roll-shaped medium 2, which consists of a fabric 9 attached to a support member 8 having an adhesive surface 7, in the transport direction F. Next, the pressing unit 5 grips and presses the dispensed medium 2. The pressing force P applied to the medium 2 by the pressing unit 5 is adjusted by the adjustment unit 6 according to the type of medium 2. Then, the recording unit 4 records data onto the medium 2 at a position downstream of the pressing unit 5 in the transport direction F.

[0034] <Description of the effects of Embodiment 1> (1) In this embodiment, the pressing unit 5 is located upstream of the recording unit 4 in the transport direction F, and the pressing unit 5 grips and presses the medium 2. Furthermore, an adjustment unit 6 is provided that can adjust the pressing force P applied to the medium 2 by the pressing unit 5. By adjusting the pressing force P, it becomes easier to attach the fabric 9 to the support member 8 with a specified adhesive force, regardless of the type of adhesive on the fabric 9 or the adhesive surface 7. Therefore, the risk of the fabric 9 peeling off the support member 8 during transport of the medium 2 or during recording by the recording unit 4 is reduced. In addition, damage to the fabric 9 that occurs when peeling it off the support member 8 can be suppressed.

[0035] (2) In this embodiment, the pressing unit 5 includes a drive roller 20 connected to the drive unit 19 and to which rotational driving force is applied, and a pressing roller 21 that rotates in conjunction with the rotation of the drive roller 20. The adjustment unit 6 includes a spring 22 connected to the pressing roller 21 and a cam 23 for adjusting the length of the spring 22. This makes it possible to adjust the pressing force P by the adjustment unit 6 with a simple structure. (3) In this embodiment, an elastic member 24 is provided on the surface of the pressing roller 21. This allows the elastic member 24 to absorb the effects of the deflection of the drive roller 20 and small irregularities on its surface, thereby enabling an appropriate pressing force P to be applied to the medium 2.

[0036] [Embodiment 2] Next, the recording device 1 according to Embodiment 2 will be described with reference to Figures 4 to 7. The same reference numerals are used for parts that are the same as those in Embodiment 1, and their configuration and corresponding effects will not be described. In this embodiment, the pressing roller 21 has a group of multiple first pressing rollers 31, 31, ... divided in the width direction (X direction) intersecting the conveying direction F of the medium 2, and a group of second pressing rollers 32, 32, ... arranged downstream of the group of first pressing rollers 31, 31, ... in the conveying direction F and to fill the gaps between the first pressing rollers 31 in the width direction (X direction). The spring 22 and the cam 23 are connected to the group of first pressing rollers 31, 31, ... and the group of second pressing rollers 32, 32, ... respectively.

[0037] Specifically, the first pressing rollers 31, 31, ... are rotatably mounted on a support shaft 39, which corresponds to the support shaft 26 of Embodiment 1. The support shaft 39 is attached to one end of the oscillating member 33. The oscillating member 33 is pivotably supported on a pivot shaft 34. One end of a spring 221, which is a spring 22, is connected to the other end of the oscillating member 33. The other end of the spring 221 is connected to a cam 23 at a connection point 37. As the cam 23 rotates as indicated by the arrow, the length of the spring 221 changes, as will be described later, and this causes the oscillating member 33 to oscillate, changing the magnitude of the pressing force P. The second pressing rollers 32, 32, ... are also rotatably mounted on a support shaft 40, which corresponds to the support shaft 26 of Embodiment 1. The support shaft 40 is attached to one end of the oscillating member 35. The oscillating member 35 is pivotably supported on a pivot shaft 36. One end of a spring 222, which is a spring 22, is connected to the other end of the oscillating member 35. The other end of the spring 222 is connected to a cam 23 at a connection point 38. As the cam 23 rotates as indicated by the arrow, the length of the spring 222 changes, as will be described later, and this causes the oscillating member 35 to oscillate and the magnitude of the pressing force P changes.

[0038] Note that in Figure 7, the support shafts 39 and 40 are omitted from the illustration to avoid complicating the drawing. In this embodiment, the support shafts 39 are individually provided on each of the multiple first pressing rollers 31, 31, ... Similarly, the support shafts 40 are individually provided on each of the multiple second pressing rollers 32, 32, ... Furthermore, the support shafts 39 and 40 may not be separate as described above, but rather each may be composed of a single shaft, and they may be configured to rotatably support the group of first pressing rollers 31, 31, ... and the group of second pressing rollers 32, 32, ... respectively.

[0039] <Adjusting the pressing force> In the state shown in Figure 4, tensile forces corresponding to the respective spring lengths of springs 221 and 222 are applied to the oscillating members 33 and 35. As a result, the oscillating members 33 and 35 oscillate around the pivot axis 34 and pivot axis 36, and the groups of first pressing rollers 31, 31, ... and the groups of second pressing rollers 32, 32, ... press the medium 2 with the corresponding pressing force P. From the state shown in Figure 4, the cam 23 is rotated to the state shown in Figure 5. In the state shown in Figure 5, the spring lengths of both spring 221 and spring 222 become shorter than in the state shown in Figure 4. As a result, the tensile force applied to the oscillating member 33 and the oscillating member 35 is reduced, and the corresponding pressing forces of the first pressing roller group 31,31,... and the second pressing roller group 32,32,... can be adjusted in a direction that decreases.

[0040] The cam 23 is further rotated to change the state from that shown in Figure 5 to that shown in Figure 6. In the state shown in Figure 6, the springs 221 and 222 have become even shorter, and neither of them is in a state where they generate a pressing force P. The oscillating members 33 and 35 are further oscillated to separate the group of first pressing rollers 31, 31, ... and the group of second pressing rollers 32, 32, ... from the medium 2. By performing the reverse operation described above, that is, by rotating the cam 23 in the direction from the state in Figure 6 to the state in Figure 5, and then to the state in Figure 4, the magnitude of the pressing force P can be adjusted to increase continuously.

[0041] In this embodiment, the pressure roller 21 has a group of first rollers 31, 31, ... divided in the width direction (X direction) intersecting the conveying direction F of the medium 2, and a group of second rollers 32, 32, ... arranged downstream of the group of first rollers 31, 31, ... in the conveying direction F and to fill the gaps between the first rollers 31 in the width direction (X direction). That is, the pressure roller 21 is divided into a group of first rollers 31, 31, ... and a group of second rollers 32, 32, ... Furthermore, springs 221, 222 and cams 23 are connected to the group of first rollers 31, 31, ... and the group of second rollers 32, 32, ... respectively. This eliminates the need to increase the diameter of the rollers, thereby suppressing an increase in size.

[0042] [Embodiment 3] Next, the recording device 1 according to Embodiment 3 will be described with reference to Figure 8. The same reference numerals are used for parts that are the same as in Embodiment 1, and the explanation of their configuration and corresponding effects will be omitted. In this embodiment, as described above, a transport roller 121 is provided, which is located downstream of the pressing section 5 in the transport direction F and transports the medium 2. Furthermore, the pressing section 5 includes a drive roller 20 connected to the drive section 19 and to which rotational driving force is applied, and a pressing roller 21 that rotates in accordance with the movement of the medium 2 being clamped by the drive roller 20. The adjustment section 6 is configured to adjust the pressing force P by rotating the drive roller 20 in the reverse transport direction (+Y direction), which is the opposite direction to the transport direction F. That is, the pressing force P is adjusted by changing the rotational speed of the drive roller 20 in the reverse transport direction (+Y direction). Furthermore, in this embodiment, the rotational speed of the drive roller 20 is set to be greater than the rotational speed of the conveyor roller 121, so that the pressing force P can be adjusted efficiently.

[0043] In this embodiment, an elastic member 24 is provided on the surface of the drive roller 20, and a low-friction material 45 is provided on the surface of the elastic member 24. The low-friction material 45 is not limited to a specific material, and any material generally considered to be a low-friction material may be used. Furthermore, as shown in Figure 8, the diameter of the drive roller 20 is set to be larger than the diameter of the conveyor roller 121.

[0044] <Adjusting the pressing force> As shown in Figure 8, the medium 2 receives a conveying force in the conveying direction F from the conveying roller 121 of the conveying unit 12, and also receives a force from the drive roller 20 in the opposite direction to the conveying direction F (+Y direction). Increasing the rotational speed of the drive roller 20 in the opposite direction (+Y direction) increases the pressing force P, and decreasing the rotational speed decreases the pressing force P.

[0045] <Explanation of the effects of Embodiment 3> (1) In this embodiment, a transport roller 121 for transporting the medium 2 is provided downstream of the pressing section 5. The pressing section 5 has a drive roller 20 connected to a drive section 19 to which rotational driving force is applied, and a pressing roller 21 that rotates in accordance with the movement of the medium 2 that is clamped between the drive roller 20 and the drive roller 20. Furthermore, the adjustment section 6 adjusts the pressing force P by rotating the drive roller 20 in the reverse transport direction (-Y direction), which is the opposite direction to the transport direction F. As a result, the medium 2 receives a transport force from the transport roller 121 in the transport direction F and a force from the drive roller 20 in the opposite direction to the transport direction F, so that the pressing force P can be efficiently increased.

[0046] (2) In this embodiment, an elastic member 24 is provided on the surface of the drive roller 20, and a low-friction material 45 is provided on the surface of the elastic member 24. The surface of the drive roller 20 elastically deforms and presses against the medium 2 in a way that crushes it, so that it makes surface contact with the medium 2 rather than line contact. As a result, the medium 2 is subjected to friction by a force from the drive roller 20 in the opposite direction to the conveying direction F, but the pressing force P can be adjusted while damage is suppressed by the elastic member 24 and the low-friction material 45.

[0047] (3) In this embodiment, the rotational speed of the drive roller 20 is set to be greater than the rotational speed of the transport roller 121. This allows for efficient adjustment of the pressing force P. (4) In this embodiment, the diameter of the drive roller 20 is larger than the diameter of the conveyor roller 121. This ensures a larger contact area with the medium 2 and allows for efficient application of the pressing force P.
