Description

Technical Field

[0001] This invention relates to a recording device such as a printer and a recording method. Background Technology

[0002] As an example of prior art for such a device, the device described in Patent Document 1 can be cited.

[0003] When printing directly onto fabric, it is prone to stretching and deformation. As a means of suppressing this stretching, a method is used to adhere the fabric to an adhesive sheet for printing. However, when the user performs the task of adhering the fabric to the adhesive sheet, the pressure applied during adhesion varies depending on the user, making it difficult to consistently achieve the desired adhesion force.

[0004] Patent Document 1 discloses an image forming apparatus comprising an adhesion unit for adhering a printing substrate (film) fed from a roll onto an adhesive surface of a support substrate (film) fed from a roll-shaped feed roller to form a composite substrate.

[0005] The adhesive force varies depending on the compatibility between the adhesive on the bonding surface and the fabric. Therefore, it is necessary to adjust the pressing pressure of the adhesive unit according to the type of adhesive and the type of fabric. However, in the aforementioned Patent Document 1, no consideration was given to adjusting the pressing pressure.

[0006] When pressing with a force less than the specified adhesion force, the fabric may peel off the adhesive sheet as it passes through the flexural path or the conveyor roller, or when ink is sprayed onto the fabric for printing, resulting in printing failure. Conversely, when pressing with a force greater than the specified adhesion force, peeling the fabric off the adhesive sheet may sometimes apply a load greater than necessary, causing damage to the fabric.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2013-6315 Summary of the Invention To solve the above-mentioned problems, the recording device according to the present invention is characterized by comprising: an unwinding section that unwinds a roll of medium formed by adhering fabric to a support member having an adhesive surface in a transport direction; a recording section that performs recording on the medium; a pressing section that is located upstream of the recording section in the transport direction and clamps and presses the medium moving in the transport direction; and an adjusting section that can adjust the pressing force toward the medium generated by the pressing section.

[0008] Furthermore, the recording method of the present invention is characterized in that a roll of medium formed by adhering fabric to a support member having an adhesive surface is unwound in the transport direction, the unwound medium is clamped and pressed by a pressing part, the pressing force generated by the pressing part toward the medium is adjusted according to the type of medium, and recording is performed on the medium by a recording part at a position downstream in the transport direction compared to the pressing part.

[0016] Figure 8 This is an enlarged side view of the main parts of Embodiment 3. Detailed Implementation

[0017] The present invention will now be described schematically.

[0018] To solve the above-mentioned problems, the recording device according to the first aspect of the present invention is characterized by comprising: an unwinding section that unwinds a roll of medium formed by adhering fabric to a support member having an adhesive surface in a transport direction; a recording section that performs recording on the medium; a pressing section that is located upstream of the recording section in the transport direction and clamps and presses the medium moving in the transport direction; and an adjusting section that is capable of adjusting the pressing force toward the medium generated by the pressing section.

[0019] According to this method, the pressing part is located upstream of the recording part in the transport direction, and the pressing part clamps and presses the medium. An adjustment part is also provided, which can adjust the pressing force generated by the pressing part towards the medium. Therefore, by adjusting the pressing force, the fabric can be easily adhered to the support member with a predetermined adhesive force, regardless of the type of adhesive on the fabric and the adhesive surface. Thus, the possibility of the fabric peeling off from the support member during the transport of the medium or during the recording process performed by the recording part can be reduced. Furthermore, damage to the fabric that occurs when it peels off from the support member can be suppressed.

[0020] The recording device according to the second aspect of the present invention is a subordinate aspect of the first aspect, characterized in that the pressing part has: a drive roller connected to the drive part and subjected to a rotational driving force; a pressing roller that rotates passively in conjunction with the rotation of the drive roller; and the adjusting part has: a spring connected to the pressing roller; and a cam that adjusts the length of the spring.

[0021] According to this method, the pressing part includes a drive roller connected to the driving part and subjected to a rotational driving force, and a pressing roller that rotates in conjunction with the rotation of the drive roller. Furthermore, the adjusting part includes a spring connected to the pressing roller and a cam for adjusting the length of the spring. Thus, the adjustment of the pressing force implemented by the adjusting part can be achieved with a simple structure.

[0022] The recording device involved in the third aspect of the present invention is a subordinate aspect of the second aspect, characterized in that an elastic member is provided on the surface of the pressing roller.

[0023] According to this method, an elastic member is provided on the surface of the pressing roller. This allows the elastic member to absorb the deflection of the drive roller and the effects of minor surface irregularities, thereby applying appropriate pressing force to the medium.

[0024] The recording device according to the fourth aspect of the present invention is a subordinate aspect of the second aspect, characterized in that the pressing roller has: a group of a plurality of first pressing rollers, the group of a plurality of first pressing rollers being divided in the width direction of the medium intersecting the conveying direction; a group of second pressing rollers, the group of second pressing rollers being configured to fill the gaps between the first pressing rollers downstream of the group of first pressing rollers in the conveying direction and between the first pressing rollers in the width direction, the spring and the cam being respectively connected to the group of first pressing rollers and the group of second pressing rollers.

[0025] When the pressing roller is made of a single piece, the roller diameter needs to be increased in order to absorb the deflection of the shaft, resulting in a large size.

[0026] According to this method, the pressing roller has: a group of multiple first pressing rollers, the group of multiple first pressing rollers being divided in the width direction of the medium intersecting the conveying direction; and a group of second pressing rollers, the group of second pressing rollers being arranged to fill the gaps between the first pressing rollers downstream of the group of first pressing rollers in the conveying direction and between the first pressing rollers in the width direction. That is, the pressing roller is divided into a group of first pressing rollers and a group of second pressing rollers. Furthermore, the spring and the cam are respectively connected to the group of first pressing rollers and the group of second pressing rollers. Therefore, it is not necessary to increase the roller diameter, thus suppressing the need for large-scale production.

[0027] The recording apparatus according to the fifth aspect of the present invention is a subordinate aspect of the first aspect, characterized in that it includes a conveying roller disposed downstream of the pressing portion in the conveying direction and conveying a medium, the pressing portion having: a drive roller connected to the drive portion and subjected to a rotational driving force; and a pressing roller driven to rotate by moving the medium held by the drive roller, and the adjusting portion adjusting the pressing force by rotating the drive roller in a reverse conveying direction opposite to the conveying direction.

[0028] According to this method, a conveying roller for conveying the medium is provided downstream of the pressing section. The pressing section includes: a drive roller connected to the drive section and subjected to a rotational driving force; and a pressing roller that is driven to rotate by the movement of the medium held by the drive roller. Furthermore, the adjusting section adjusts the pressing force by rotating the drive roller in a reverse conveying direction opposite to the conveying direction. Thus, the medium is subjected to a force in the opposite direction from the drive roller while being conveyed by the conveying roller in the conveying direction, thereby efficiently increasing the pressing force. Moreover, the pressing force can be adjusted by changing the rotational speed of the drive roller in the reverse conveying direction.

[0029] The recording device according to the sixth aspect of the present invention is a type subordinate to 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.

[0030] According to this method, 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. Since the surface of the drive roller presses the medium in a manner that causes it to be crushed through elastic deformation, the contact with the medium is not line contact but surface contact. Therefore, although the medium is subjected to friction from the drive roller by a force in the opposite direction to the conveying direction, the pressing force can be adjusted while suppressing damage caused by the elastic member and the low-friction material.

[0031] The recording device involved in the seventh aspect of the present invention is a type subordinate to the fifth aspect, characterized in that the rotational speed of the drive roller is greater than the rotational speed of the conveying roller.

[0032] In addition, this method can also be subordinate to the sixth method.

[0033] According to this method, the rotational speed of the drive roller is set to be larger than the rotational speed of the conveying roller. This allows for efficient adjustment of the pressing pressure.

[0034] The recording device involved in the eighth aspect of the present invention is a type subordinate to the fifth aspect, characterized in that the diameter of the drive roller is larger than the diameter of the conveying roller.

[0035] In addition, this method can also be subordinate to the sixth or seventh method.

[0036] According to this method, the diameter of the drive roller is larger than the diameter of the conveying roller. Therefore, by making the diameter larger, a larger contact area with the medium can be ensured, thereby efficiently applying pressing pressure.

[0037] The recording method according to the ninth aspect of the present invention is characterized in that a roll of medium formed by adhering fabric to a support member having an adhesive surface is unwound in a transport direction, the unwound medium is clamped and pressed by a pressing part, the pressing force generated by the pressing part toward the medium is adjusted according to the type of medium, and recording is performed on the medium by a recording part at a position downstream in the transport direction compared to the pressing part.

[0038] This method achieves the same effect as the first method.

[0039] Implementation Hereinafter, the recording apparatus and recording method according to the embodiments of the present invention will be described based on Figures 1 to 8Let us now provide a detailed explanation. Here, we will explain the case where the recording device is an inkjet printer.

[0040] In the following description, as shown in the figures, the three mutually orthogonal axes are designated as the X-axis, Y-axis, and Z-axis. The arrows marking the three axes (X, Y, Z) indicate the positive (+) direction and the negative (-) direction, respectively. The Z-axis corresponds to the vertical direction, i.e., the direction of gravity; +Z indicates vertically upward, and -Z indicates vertically downward. The X-axis and Y-axis correspond to the horizontal direction. +Y indicates the forward direction of the recording device, and -Y indicates the backward direction. +X indicates the rightward direction of the recording device, and -X indicates the leftward direction.

[0041] Implementation Method 1 The recording device 1 in this embodiment is an inkjet printer as an example.

[0042] like Figure 1 As shown, the recording device 1 includes an unwinding section 3 for unwinding the medium 2 in the conveying direction F, a recording section 4, a pressing section 5, and an adjusting section 6.

[0043] The medium 2 is a roll-shaped medium formed by adhering a sheet-like fabric 9 to a sheet-like support member 8 having an adhesive surface 7. The medium 2 is placed on the unwinding section 3 in the roll body R1 state. The unwinding section 3 rotates the roll body R1 to unwind the medium 2 in the transport direction F. The recording section 4 sprays ink onto the unwound fabric 9 of the medium 2 in the recording execution area 10 to perform recording. In the recording execution area 10, the medium 2 is supported by the medium support section 11.

[0044] The pressing unit 5 is located upstream of the recording unit 4 in the conveying direction F. The pressing unit 5 is configured to clamp the medium 2 moving in the conveying direction F and apply a pressing force P to perform pressing. The adjusting unit 6 is configured to adjust the pressing force P generated by the pressing unit 5 towards the medium 2. The specific structures of the pressing unit 5 and the adjusting unit 6 will be described later.

[0045] like Figure 1 As shown, the recording device 1 also includes a conveying section 12 that applies a conveying force to the medium 2 toward the recording section 4, intermediate rollers 13 and 14, a drying treatment section 15, an end roller pair 16, a fabric winding section 17, and a support member winding section 18.

[0046] The conveying unit 12 consists of a conveying roller 121 that rotates due to power transmitted from a drive source, and a pressing roller 122 that rotates following the rotation of the conveying roller 121. Intermediate rollers 13 and 14 are positioned to change the conveying direction of the medium 2 and rotate passively as the medium 2 moves in the conveying direction F. The drying unit 15 heats the medium 2 after ink has been sprayed out to dry it. The end roller 16 clamps the medium 2 and rotates passively as the medium 2 moves.

[0047] The fabric winding section 17 only winds up the fabric 9 to form the roll body R3. The support member winding section 18 is positioned separately from the fabric winding section 17 and only winds up the support member 8 to form the roll body R2. That is, the medium 2 is configured such that, while being held by the end roller 16, the fabric winding section 17 only winds up the fabric 9 and the support member winding section 18 only winds up the support member 8, thereby separating the two.

[0048] Pressing and adjusting parts Next, regarding the structure of the pressing part 5 and the adjusting part 6 of the recording device 1 according to Embodiment 1, based on Figures 1 to 3 Let me explain.

[0049] The pressing part 5 is composed of a drive roller 20 and a pressing roller 21. The drive roller 20 and the drive part 19 ( Figure 1 The drive unit 20 is powered and subjected to a rotational driving force. The drive roller 20 is integrally mounted on the rotating shaft 25. Both ends of the rotating shaft 25 are rotatably supported on structural components such as a frame (not shown). The drive roller 20 rotates integrally by utilizing the rotational driving force of the drive unit 19 to rotate the rotating shaft 25 around its axis.

[0050] exist Figure 3 To avoid complicating the accompanying drawings, the diagram of the rotation axis 25 has been omitted.

[0051] The pressing roller 21 rotates in response to the rotation of the drive roller 20. The pressing roller 21 is rotatably mounted on the support shaft 26. That is, the pressing roller 21 is configured to rotate relative to the support shaft 26 in response to the rotation of the drive roller 20. In other words, the pressing roller 21 rotates in response to the conveying force generated by the rotation of the drive roller 20 on the medium 2 held by the drive roller 20, causing it to move in the conveying direction F.

[0052] In this embodiment, the release cam 27 contacts the support shaft 26. When the medium 2 is placed by passing it between the drive roller 20 and the pressing roller 21, the distance between the drive roller 20 and the pressing roller 21 can be increased by rotating the release cam 27.

[0053] In this embodiment, an elastic member 24 is provided on the surface of the pressing roller 21. The elastic member 24 is made of rubber material.

[0054] In this embodiment, the adjustment unit 6 has a spring 22 connected to the pressing roller 21 and a cam 23 for adjusting the length of the spring 22.

[0055] Specifically, such as Figure 3 As shown, one end of the spring 22 is fixed to the support shaft 26 of the pressing roller 21, and the other end is fixed to the cam 23. The spring 22 is set in a tension spring state and is configured to apply a pressing force P to the medium 2 by stretching the pressing roller 21 toward the drive roller 20. The spring 22 is configured such that its length changes, i.e., the tension force changes, by rotating the cam 23, thereby allowing the magnitude of the pressing force P to be continuously changed for adjustment.

[0056] In order to allow adjustment of the pressing force P, both ends of the support shaft 26 are supported on structural components such as a frame (not shown) in a manner that allows the pressing force P to be increased or decreased.

[0057] In this embodiment, for various types of media 2 intended for use, the appropriate pressing pressure P is determined in advance through trial production or the like. Furthermore, the system is configured such that the cam 23 rotates by the user performing a specific operation on the type of media 2 via an operation panel (not shown), thereby applying the corresponding pressing pressure P to the media 2.

[0058] For a new medium 2 that is not intended for use, the user can test or modify the rotation state of the cam 23 based on experience, thereby enabling the appropriate pressing force to be applied to the medium 2.

[0059] That is, it is configured to adjust the pressing force P generated by the pressing part 5 toward the medium 2 according to the type of medium 2.

[0060] The actions of the unwinding section 3, pressing section 5, conveying section 12, recording section 4, drying section 15, fabric winding section 17, and support component winding section 18 are controlled by the control section 28. Figure 1The control unit 28 includes a CPU, a flash ROM, and RAM. The CPU performs various calculations based on the program stored in the flash ROM to control the overall operation of the recording device 1. The flash ROM, as an example of a storage unit, is a non-volatile memory that can be read and written. Various information is temporarily stored in the RAM, which is also an example of a storage unit.

[0061] Unwinding, adjusting pressure, and recording the execution. In this embodiment, as described below, recording is performed by the recording unit 4 on the medium 2 that is unwound from the unwinding unit 3.

[0062] First, the unwinding section 3 unwinds the roll of medium 2, formed by adhering fabric 9 to the support member 8 having adhesive surface 7, in the transport direction F. Next, the pressing section 5 clamps and presses the unwound medium 2. The pressing force P generated by the pressing section 5 towards the medium 2 is adjusted by the adjusting section 6 according to the type of medium 2. Furthermore, at a position downstream in the transport direction F compared to the pressing section 5, the recording section 4 records data on the medium 2.

[0063] Explanation of the effects of Implementation Method 1 (1) In this embodiment, the pressing part 5 is located upstream of the recording part 4 in the transport direction F, and the pressing part 5 clamps and presses the medium 2. An adjustment part 6 is also provided, which can adjust the pressing force P generated by the pressing part 5 towards the medium 2. Therefore, by adjusting the pressing force P, the fabric 9 can be easily adhered to the support member 8 with a predetermined adhesive force, regardless of the type of adhesive on the fabric 9 and the adhesive surface 7. Thus, the possibility of the fabric 9 peeling off from the support member 8 during the transport of the medium 2 or during the recording process performed by the recording part 4 can be reduced. Furthermore, damage to the fabric 9 that occurs when it peels off from the support member 8 can be suppressed.

[0064] (2) In addition, in this embodiment, the pressing part 5 has a drive roller 20 connected to the drive part 19 and subjected to a rotational driving force, and a pressing roller 21 that rotates along with the rotation of the drive roller 20. Furthermore, the adjusting part 6 has a spring 22 connected to the pressing roller 21 and a cam 23 for adjusting the length of the spring 22. Thus, the adjustment of the pressing force P implemented by the adjusting part 6 can be achieved with a simple structure.

[0065] (3) In addition, in this embodiment, an elastic member 24 is provided on the surface of the pressing roller 21. As a result, the elastic member 24 can absorb the effects of the deflection of the drive roller 20 and the small unevenness of the surface, so as to apply an appropriate pressing force P to the medium 2.

[0066] Implementation Method 2 Next, based on Figures 4 to 7 The recording device 1 according to Embodiment 2 will be described. The same symbols are used for the parts that are the same as in Embodiment 1, and the description of their structure and corresponding effects is omitted.

[0067] In this embodiment, the pressing roller 21 has a group of a plurality of 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 to fill the gaps between the first pressing rollers 31 in the width direction (X direction) downstream of the group of first pressing rollers 31, 31, ... in the conveying direction F.

[0068] Spring 22 and cam 23 are respectively connected to the first pressing rollers 31, 31, ... and the second pressing rollers 32, 32, ...

[0069] Specifically, the first pressing rollers 31, 31, ... are rotatably mounted on the support shaft 39, which corresponds to the support shaft 26 in Embodiment 1. The support shaft 39 is mounted at one end of the swing member 33. The swing member 33 is supported in a swinging manner by the swing fulcrum shaft 34. One end of the spring 221, which is a spring 22, is connected to the other end of the swing member 33. The other end of the spring 221 is connected to the cam 23 at the connection point 37. By rotating the cam 23 as indicated by the arrow, as described later, the length of the spring 221 changes, thereby causing the swing member 33 to swing, and thus changing the magnitude of the pressing force P.

[0070] The second pressing rollers 32, 32, ... are also rotatably mounted on the support shaft 40, which corresponds to the support shaft 26 in Embodiment 1. The support shaft 40 is mounted at one end of the swing member 35. The swing member 35 is supported in a swinging manner by the swing fulcrum shaft 36. One end of the spring 222, which is a spring 22, is connected to the other end of the swing member 35. The other end of the spring 222 is connected to the cam 23 at the connection point 38. By rotating the cam 23 as indicated by the arrow, as described later, the length of the spring 222 changes, thereby causing the swing member 35 to swing, and thus changing the magnitude of the pressing force P.

[0071] In addition, Figure 7 To avoid complicating the accompanying drawings, the support shafts 39 and 40 are omitted from the illustrations. In this embodiment, the support shaft 39 is individually provided for each of the plurality of first pressing rollers 31, 31, ... . The support shaft 40 is also individually provided for each of the plurality of second pressing rollers 32, 32, ...

[0072] Alternatively, the support shaft 39 and support shaft 40 may not be separate as described above, but may each be composed of a single shaft, supporting the first pressing rollers 31, 31, ... and the second pressing rollers 32, 32, ... in a manner that allows each to rotate independently.

[0073] Adjustment of pressure exist Figure 4 In the indicated state, a tensile force corresponding to the respective spring lengths of springs 221 and 222 is applied to the swinging components 33 and 35. As a result, the swinging components 33 and 35 swing about the swinging fulcrum axes 34 and 36, and the group of first pressing rollers 31, 31, ... and the group of second pressing rollers 32, 32, ... press the medium 2 with corresponding pressing force P.

[0074] from Figure 4 From the state shown, cam 23 rotates to become Figure 5 The state. When it becomes Figure 5 In the state where springs 221 and 222 are both of the same length as... Figure 4 The length of the pressure rollers decreases compared to the previous state. As a result, the tensile force applied to the swinging member 33 and the swinging member 35 decreases, thereby enabling adjustment in the direction that reduces the corresponding pressing force of the first pressing rollers 31, 31, ... and the second pressing rollers 32, 32, ...

[0075] Further rotate cam 23 from Figure 5 The state becomes Figure 6 The state. In Figure 6 In this state, the spring lengths of springs 221 and 222 are further shortened, and neither of them becomes a state that generates pressing force P. Instead, they become a state that causes the swinging member 33 and the swinging member 35 to swing further, thereby separating the group of first pressing rollers 31, 31, ... and the group of second pressing rollers 32, 32, ... from the medium 2.

[0076] By advancing the opposite action described above, that is, by causing cam 23 to move from... Figure 6 The state of rising and becoming Figure 5 The state, and thus become Figure 4 The direction of the state is rotated, thereby allowing the magnitude of the pressing force P to be adjusted in a continuously increasing manner.

[0077] 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 to fill the gaps between the first pressing rollers 31 downstream of the group of first pressing rollers 31, 31, ... in the width direction (X direction). That is, the pressing roller 21 is divided into a group of first pressing rollers 31, 31, ... and a group of second pressing rollers 32, 32, ... Furthermore, springs 221, 222 and cam 23 are respectively connected to the group of first pressing rollers 31, 31, ... and the group of second pressing rollers 32, 32, ... . Therefore, it is not necessary to increase the roller diameter, thus suppressing the need for large-scale production.

[0078] Implementation Method 3 Next, based on Figure 8 The recording device 1 according to Embodiment 3 will now be described. The same symbols will be used for parts identical to those in Embodiment 1, and descriptions of their structure and corresponding effects will be omitted.

[0079] In this embodiment, as described above, a conveying roller 121 is provided, which is disposed downstream of the pressing portion 5 in the conveying direction F and conveys the medium 2.

[0080] Additionally, the pressing unit 5 includes: a drive roller 20 connected to the drive unit 19 and subjected to a rotational driving force; and a pressing roller 21 driven to rotate by the movement of the medium 2 held by the drive roller 20. The adjusting unit 6 is configured to adjust the pressing force P by rotating the drive roller 20 in the reverse conveying direction (+Y direction), which is opposite to the conveying direction F. That is, it is configured to adjust the pressing force P by changing the rotational speed of the drive roller 20 in the reverse conveying direction (+Y direction).

[0081] Furthermore, in this embodiment, the rotational speed of the drive roller 20 is set to be larger than that of the conveyor roller 121, thereby enabling efficient adjustment of the pressing pressure P.

[0082] 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 materials that are generally used as low-friction materials can also be used.

[0083] And, as Figure 8 As shown, the diameter of the drive roller 20 is set to be larger than the diameter of the conveyor roller 121.

[0084] Adjustment of pressure like Figure 8 As shown, the medium 2 is in a state where it is subjected to a conveying force from the conveying roller 121 of the conveying section 12 in the conveying direction F, and is subjected to a force from the drive roller 20 in the opposite direction (+Y direction) to the conveying direction F. By accelerating the rotational speed of the drive roller 20 in the opposite direction (+Y direction), the pressing force P increases, and by decelerating the rotational speed, the pressing force P decreases.

[0085] Explanation of the effects of implementation method 3 (1) In this embodiment, a conveying roller 121 for conveying the medium 2 is provided downstream of the pressing section 5. The pressing section 5 includes: a drive roller 20, which is connected to the drive section 19 and is subjected to a rotational driving force; and a pressing roller 21, which is driven to rotate by the movement of the medium 2 held by the drive roller 20. Furthermore, the adjusting section 6 adjusts the pressing force P by rotating the drive roller 20 in the reverse conveying direction (-Y direction), which is opposite to the conveying direction F. As a result, since the medium 2 is in a state where it is conveyed by the conveying roller 121 in the conveying direction F, it is subjected to a force from the drive roller 20 in the opposite direction to the conveying direction F, thus the pressing force P can be increased efficiently.

[0086] (2) Furthermore, 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. Since the surface of the drive roller 20 presses the medium 2 in such a way that it is crushed by elastic deformation, there is surface contact with the medium 2 rather than line contact. Thus, although the medium 2 is subjected to a force from the drive roller 20 in the opposite direction to the conveying direction F and is subject to friction, the pressing force P can be adjusted to suppress damage caused by the elastic member 24 and the low-friction material 45.

[0087] (3) In addition, in this embodiment, the rotational speed of the drive roller 20 is set to be larger than the rotational speed of the conveyor roller 121. As a result, the pressing pressure P can be adjusted efficiently.

[0088] (4) Furthermore, in this embodiment, the diameter of the drive roller 20 is larger than the diameter of the conveying roller 121. Therefore, by making the diameter larger, the contact area with respect to the medium 2 can be ensured, thereby efficiently applying the pressing force P.
