Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims. Although a plurality of features are described in the embodiments, not all of these plurality of features are essential to the invention, and the plurality of features may be arbitrarily combined. Further, in the accompanying drawings, the same or similar configurations are given the same reference numerals, and duplicate explanations are omitted.

[0010] <Schematic of the recording device> Fig. 1 is a schematic diagram of a recording device 1 in the present embodiment. In the present embodiment, the case where the present invention is applied to a serial type inkjet recording device will be described, but the present invention is also applicable to other types of recording devices. In the figure, arrow X and arrow Y indicate horizontal directions orthogonal to each other, and arrow Z indicates the vertical direction. Also, when referring to the downstream side and the upstream side, it is based on the conveyance direction of the recording medium.

[0011] Note that "recording" includes not only the case of forming significant information such as characters and figures, but also the case of forming an image, pattern, pattern, etc. on the recording medium regardless of whether it is significant or not, or performing processing on the medium, regardless of whether it is manifested so that it can be perceived visually by humans. Also, in the present embodiment, a sheet-like paper is assumed as the "recording medium", but it may be cloth, plastic film, or the like.

[0012] The recording device 1 includes a feeding unit 2, a conveying unit 3, and a discharging unit 4 that are arranged from the upstream side in the conveying direction of the recording medium as a mechanism for conveying the recording medium. In the following description, the upstream side and the downstream side are based on the conveying direction of the recording medium. The feeding unit 2 includes a feeding unit 21 that feeds the sheet SH1 as the recording medium and a feeding unit 22 that feeds a sheet SH2 different from the sheet SH1 as the recording medium. In this embodiment, the two feeding units 21 and 22 can selectively feed the recording medium for recording.

[0013] The feeding unit 21 includes a feeding tray 210 (loading portion) capable of stacking a plurality of sheets SH1, a feeding roller 211, and a separating unit 213. The sheet SH1 is a cut sheet stacked on the feeding tray 210 in a posture where its width direction is the Y direction (hereinafter, may be referred to as the cut sheet SH1). The feeding roller 211 rotates by the driving force of the feeding motor 212, abuts against the uppermost cut sheet SH1 stacked on the feeding tray 210, and conveys it to the downstream side. A separating unit 213 is provided at the downstream end of the feeding tray 210. The separating unit 213 has a structure (for example, separating claws) that separates the cut sheets SH1 on the feeding tray 210 one by one when the cut sheet SH1 is conveyed by the feeding roller 211.

[0014] The sheet SH2 is a roll sheet in which a single sheet is wound around a cylindrical core material (hereinafter, may be referred to as the roll sheet SH2). The feeding unit 22 has a support portion 221 that rotatably supports the roll sheet SH2. The roll sheet SH2 is supported in a posture where its width direction (axial direction of the roll) is the Y direction. The support portion 221 rotates by the driving force of the feeding motor 222 to rotate the roll sheet SH2. Depending on the rotation direction of the feeding motor 222, a feeding operation and a winding operation for feeding the roll sheet SH2 to the downstream side are possible. The feeding unit 22 includes a roller 223 that is pressed against the outer peripheral surface of the roll sheet SH2 by a spring or the like (not shown). The roller 223 is a freely rotatable body and presses the outer peripheral surface of the roll sheet SH2 so that the feeding operation and the winding operation of the roll sheet SH2 are performed stably.

[0015] The roll sheet SH2 is transported downstream by the rotation of the support section 221, passing between the sheet guide 10 and the roller 224, which is a freely rotating body positioned opposite the sheet guide 10. The transport path for the cut sheet SH1 and the transport path for the roll sheet SH2 merge at the junction downstream of the partition member 10c. After merging, the transport path passes between the sheet guide 10a and the sheet guide 10b opposite to the sheet guide 10a to reach the transport unit 3.

[0016] The transport unit 3 is positioned upstream of the recording head 6 and transports the recording medium (cut sheet SH1 or roll sheet SH2) transported by the feeding unit 2 to the recording head 6. The transport unit 3 includes a drive roller 31 and a driven roller 32 (pinch roller) which is pressed against the drive roller 31 by a spring or the like (not shown). The drive roller 31 rotates due to the driving force of the transport motor 33. When the transport motor 33 rotates forward, the recording medium is held between the nip portion of the drive roller 31 and the driven roller 32, and the recording medium (cut sheet SH1 or roll sheet SH2) is transported downstream in the X direction between the recording head 6 and the support member 8. In addition, when the roll sheet SH2 is being wound up, the transport unit 3 can also transport the roll sheet SH2 upstream by reversing the transport motor 33.

[0017] The support member 8 is a member that supports the recording medium being transported by the transport unit 3 from below. In this embodiment, the support member 8 is a single member, but it may be composed of multiple members divided in the X direction. The regulating member 12 is positioned opposite the support member 8 and regulates the height of the recording medium from above, thereby preventing the recording medium from floating up.

[0018] The discharge unit 4 is located downstream of the recording head 6 and transports the recording medium (cut sheet SH1 or roll sheet SH2) transported by the transport unit 3 to the outside of the device. The discharge unit 4 includes a drive roller 41 and a spur 42 located opposite the drive roller 41 and pressed against the drive roller 41 by a spring (not shown). The drive roller 41 is a rotating member that rotates by the driving force of the transport motor 33 and transports the recording medium downstream. The spur 42 is a rotating member that can rotate together with the drive roller 41, and the recording medium is held and transported in the nip portion between the drive roller 41 and the spur 42.

[0019] In this embodiment, the transport motor 33 is shared between the transport unit 3 and the discharge unit 4, but a configuration in which separate motors are provided for each unit is also possible.

[0020] A cutting unit 5 is provided downstream of the discharge unit 4. The cutting unit 5 cuts the recorded roll sheet SH2. The cutting unit 5 includes, for example, a cutter having circular blades arranged one above the other, and a moving mechanism (not shown) that moves the cutter in a direction intersecting the transport direction of the recording medium (in this embodiment, the Y direction). The cutter is waiting outside the transport path of the recording medium and is moved to cross the transport path to cut the roll sheet SH2 when cutting is required.

[0021] The recording head 6 is located downstream of the transport unit 3 and upstream of the discharge unit 4. The recording head 6 records onto the recording medium (cut sheet SH1 or roll sheet SH2). In this embodiment, the recording head 6 is an inkjet recording head that ejects ink to record onto the recording medium. The recording head 6 is supported by the carriage 7.

[0022] The carriage 7 reciprocates in a direction intersecting the recording medium by the drive unit 11. In this embodiment, the carriage 7 reciprocates in the Y direction guided by a guide shaft 9 extending in the Y direction. The drive unit 11 is a mechanism driven by a carriage motor 11a, and is, for example, a belt drive mechanism comprising a drive pulley and a driven pulley spaced apart in the Y direction, and an endless belt wound around these pulleys. The carriage 7 is connected to the endless belt. When the carriage motor 11a rotates the drive pulley, the endless belt travels and the carriage 7 moves. The recording head 6 may be interchangeably mounted on the carriage 7.

[0023] As described above, the recording device 1 of this embodiment is a serial type recording device in which a recording head 6 is mounted on a carriage 7. Recording control for the recording medium is performed by repeatedly performing a transport operation (intermittent transport operation) in which a predetermined amount of recording medium is transported by a transport unit 3, and a recording operation while the transport unit 3 is stopped transporting. The recording operation is the operation of ejecting ink from the recording head 6 while moving the carriage 7 on which the recording head 6 is mounted.

[0024] The recording device 1 includes a detection unit 13. The detection unit 13 detects the recording medium at a position upstream of the transport unit 3 and downstream of the feeding unit 2. The detection unit 13 is, for example, an optical sensor that detects the recording medium. Alternatively, the detection unit 13 is, for example, composed of an arm member that is pivotably mounted in the transport path of the recording medium and pivots in response to interference with the recording medium, and a sensor that detects the pivoting of the arm member.

[0025] <Control Unit> Figure 2 is a block diagram of the control unit 14 of the recording device 1. The MPU 140 is a processor that controls the operation of each function of the recording device 1 and processes data. The MPU 140 executes programs stored in the storage device 141 to control the entire recording device 1. The storage device 141 is composed of, for example, ROM or RAM. The storage device 141 stores various data necessary for processing, such as programs executed by the MPU 140 and data received from the host computer 15.

[0026] The MPU 140 controls the recording head 6 via driver 142a. The MPU 140 controls the carriage motor 11a via driver 142b. The MPU 140 also controls the transport motor 33, feed motor 212 and via drivers 142c to 142f. 222 It also controls the cutter motor 5a. The cutter motor 5a is the drive source for the cutting unit 5.

[0027] The host computer 15 is, for example, a personal computer or mobile device (such as a smartphone or tablet) used by the user. The host computer 15 has a printer driver 15a installed that enables communication between the host computer 15 and the recording device 1. The recording device 1 is equipped with an interface unit 143, and communication between the host computer 15 and the MPU 140 is performed via the interface unit 143. For example, when the user inputs a request to execute recording control to the host computer 15, the printer driver 15a gathers the data of the image to be recorded and settings related to recording (information such as the quality of the recorded image) and instructs the recording device 1 to execute recording control. The instruction to execute recording control is sometimes called a recording job.

[0028] <Suppression of floating> The structure for suppressing the lifting of the recording medium will be described with reference to Figures 3 to 5. Figure 3 is a plan view of the support member 8, and also shows the spur 42 and the regulating member 12. Figure 4 is a cross-sectional view of Figure 3 along line AA, and Figure 5 is a cross-sectional view of Figure 3 along line BB.

[0029] The support member 8 has a plurality of ribs 8a and 8b arranged in the Y direction. Each rib 8a and 8b is a plate-shaped member extending in the X direction, and its top forms the transport support surface for the recording medium. In this embodiment, the heights (lengths in the Z direction) of the ribs 8a and ribs 8b are different. Since a plurality of ribs 8b with relatively low heights are arranged between ribs 8a with relatively high heights, even if the recording medium stretches after ink is applied, the recording medium can be supported along the ribs 8b with relatively low heights. Figure 5 illustrates an embodiment in which a stretched roll sheet SH2 is supported by ribs 8a and ribs 8b. In other words, it is possible to prevent the recording medium from stretching upwards, and to prevent the recording medium from coming into contact with the recording head 6.

[0030] Note that rib 8a and rib 8b differ only in height; their contour shape (profile in the XZ plane) is the same. The following explanation will mainly describe the configuration of rib 8a, but rib 8b is similar.

[0031] The rib 8a has multiple parts in the X direction. Specifically, the rib 8a has a platen portion 80 and a guide portion 81. The platen portion 80 is the part that faces the recording head 6 and forms a flat support surface in the X direction.

[0032] Information department 81 This is the part that guides the movement of the leading edge of the recording medium after it has passed through the recording head 6. 81 The structure has, in order from the upstream side, a downward inclined section 82, a connecting section 83, a downward inclined section 84, and an upward inclined section 85. The downward inclined section 82 starts at a position slightly upstream of the downstream end (downstream nozzle) of the recording head 6 in the X direction, and forms a downward inclination that slopes downstream toward the downstream side, away from the support height H1 of the recording medium at the platen section 80. The inclination is a straight inclination without curvature. The connecting section 83 is the section that connects the downward inclined section 82 and the downward inclined section 84, and is a flat surface parallel to the support height H1. It is also possible to form the downward inclined section 82 and the downward inclined section 84 continuously without providing the connecting section 83.

[0033] The downward inclined portion 84 forms a downward inclination that slopes in a direction away from the support height H1 toward the downstream side. However, the inclination is gentler than that of the downward inclined portion 82. The inclination is a straight inclination without curvature. The upward inclined portion 85 forms an upward inclination that slopes in a direction approaching the support height H1 toward the downstream side. The upward inclined portion 85 includes an upstream curved portion 85a and a straight portion 85b that continues from the curved portion 85a toward the downstream side. The curved portion 85a is a portion that extends in an arc shape so that the inclination smoothly transitions from the downward inclined portion 84 to the upward inclination from the lower end of the downward inclined portion 84. The straight portion 85b is a straight inclined surface without curvature.

[0034] In the case of the present embodiment, the regulating member 12 is a rotating member having the same form as the impeller 42 and is freely rotatable around the axis 12a in the Y direction. Note that the form of the regulating member 12 only needs to be able to contact the recording medium and prevent its lifting. In addition to the rotating member as in the present embodiment, it may be a fixed member. However, by using a rotating member as in the present embodiment, the conveyance of the recording medium with its lifting regulated can be continued more smoothly.

[0035] The regulating member 12 is disposed at a position facing the guide portion 81, and particularly, at a position facing the downward inclined portion 84. By disposing the regulating member 12 at such a position, when the leading end of the recording medium advances from the downward inclined portion 84 to the upward inclined portion 85 and the recording medium turns into a lifted state, the regulating member 12 can more reliably regulate the lifting of the recording medium. Also, the relationship among the support height H 1 of the platen portion 80, the regulating position (regulating height) H 2 of the regulating member 12, and the height H 3 of the nip position of the discharge unit 4 is H 1 < H 2 < H 3. Due to such a height relationship, the regulating member 12 can more reliably regulate the lifting of the recording medium.

[0036] A plurality of regulating members 12 are provided and are provided at positions corresponding to the ribs 8a and 8b in the Y direction. More specifically, each regulating member 12 is disposed so as to face either rib 8a or 8b. Thereby, the lifting of the recording medium can be regulated at an arbitrary portion in the width direction (Y direction) of the recording medium.

[0037] Figures 6(A) to 7(B) are explanatory diagrams illustrating examples of how the lifting of the recording medium is restricted. While this example describes the transport of a roll sheet SH2, the same principles apply to cut sheets SH1.

[0038] Figure 6(A) shows the stage where the leading edge of the roll sheet SH2 is moving on the platen section 80. At this stage, ink may be ejected from the recording head 6 and recording may begin. As the transport of the roll sheet SH2 progresses, as shown in Figure 6(B), the leading edge of the roll sheet SH2 reaches the connection section 83 via the downward inclined section 82.

[0039] The downward-sloping section 82 guides the tip of the roll sheet SH2 downwards, preventing it from lifting towards the recording head 6 even if it is curled downwards. In particular, because the downward-sloping section 82 has a relatively steep downward slope, it can reduce the lifting of the roll sheet SH2 even if the curl near the tip of the roll sheet SH2 is strong.

[0040] As the transport of the roll sheet SH2 progresses, the leading edge of the roll sheet SH2 reaches the downward inclined section 84, as shown in Figure 6(C). The downward inclined section 84 guides the leading edge of the roll sheet SH2 downwards, allowing the roll sheet SH2 to maintain a state of minimal lifting. If the downward inclined section 84 were a flat surface similar to the connecting section 83, the lifting of the roll sheet SH2 may increase depending on the curl state of the roll sheet SH2. However, by guiding the leading edge of the roll sheet SH2 with the relatively gentle downward inclined section 84, the growth of the roll sheet SH2's lifting is suppressed. The downward inclined section 84 is the longest section in the X direction in the guide section 81, and is longer than the individual sections of the downward inclined section 82 and the connecting section 83, or the combined section of the downward inclined section 82 and the connecting section 83. The downward inclined section 84 allows the transport distance from the recording head 6 to the discharge unit 4 to be secured while suppressing the growth of the roll sheet SH2's lifting.

[0041] As the transport of the roll sheet SH2 progresses, the leading edge of the roll sheet SH2 reaches the upward inclined section 85, as shown in Figure 7(A). As a result, the roll sheet SH2 begins to lift up. However, as shown in Figure 7(A), the lifting of the roll sheet SH2 is restricted by the restricting member 12, thus preventing the roll sheet SH2 from lifting up directly below the recording head 6.

[0042] In this embodiment, the downward inclined section 84 and the upward inclined section 85 are made continuous in order to control the position at which the lift of the roll sheet SH2 grows. That is, in the downward inclined section 84, the growth of the lift of the roll sheet SH2 is suppressed by the downward inclination, while it grows rapidly in the upward inclined section 85. In particular, since a curved section 85a is formed at the upstream end of the upward inclined section 85, the lift of the roll sheet SH2 grows rapidly. However, the lift of the roll sheet SH2 can be suppressed by the regulating member 12.

[0043] In this embodiment, the position where the roll sheet SH2 lifts up is structurally limited, while the lifting of the roll sheet SH2 is restricted by the restricting member 12 in accordance with this position. This prevents the position where lifting occurs from fluctuating depending on the stiffness and degree of curl of the roll sheet SH2, thereby controlling the position where lifting occurs and effectively suppressing lifting.

[0044] As the roll sheet SH2 is transported, the leading edge of the roll sheet SH2 reaches the nip of the discharge unit 4, as shown in Figure 7(B). Since the height H3 of the nip position of the discharge unit 4 is higher than the regulating position H2 of the regulating member 12, the lifting of the roll sheet SH2 is continuously restricted by the regulating member 12.

[0045] In this embodiment, the position at which the recording medium lifts can be controlled and suppressed. According to this embodiment, even if the platen section 80 does not have a structure for sucking the recording medium, for example, the lifting of the recording medium can be suppressed, and a recording device 1 can be provided at low cost and in a small size.

[0046] <Height adjustment structure for restricting members> The structure for adjusting the height of the regulating member 12 will now be described. By adjusting the height of the regulating member 12, the floating of the recording medium can be suppressed more reliably. As shown in Figure 4, the regulating member 12 is supported by the holding member 16 together with the spur 42. The spur 42 is rotatably supported by the holding member 16 via a spring shaft 42a and is biased by the discharge roller 41 via the spring shaft 42a. The regulating member 12 is supported by the holding member 16 via a shaft 12a.

[0047] A height adjustment member 18 is interposed between the holding member 16 and the base member 17, and the holding member 16 is supported by the base member 17 via the height adjustment member 18. The base member 17 is fixed to the frame (not shown) of the recording device 1. The height adjustment member 18 has a plate portion 180 on the YZ plane and a plate portion 181 on the XY plane that is bent from the plate portion 180, and has an overall vertical cross-sectional shape of L. The height adjustment member 18 can be made of an L-shaped sheet metal member and can be made relatively thin. This prevents the recording device 1 from becoming larger. The base member 17 and the height adjustment member 18 are fixed together by a screw 50 at one plate portion 180, and the height adjustment member 18 and the holding member 16 are fixed together by a screw 51 via a spacer 19 at the other plate portion 181.

[0048] Further explanation will be given with reference to Figures 8 to 10. Figure 8 is a perspective view of the assembly of the holding member 16, base member 17, and height adjustment member 18, and Figure 9 is an exploded perspective view thereof. Figures 8 and 9 omit the spur 42 and regulating member 12. Figure 10 is an enlarged view of part P in Figure 8, showing the state with the screw 50 removed.

[0049] The retaining member 16, the base member 17, and the height adjustment member 18 are all elongated members extending in the Y direction. The base member 17 has multiple fixing holes 17a formed in the Y direction through which the screw shafts of the screws 50 pass, and the height adjustment member 18 has multiple screw holes 18a formed in the Y direction corresponding to the fixing holes 17a, into which the screws 50 are screwed. The retaining member 16 and the height adjustment member 18 are fixed together by screws 51 at multiple points in the Y direction.

[0050] The fixing hole 17a is a hole with a diameter larger than the screw shaft of the screw 50, and as shown by arrow Z1 in Figure 10, it has a size that allows the position through which the screw shaft passes to be changed vertically. In other words, the relative fixing position in the Z direction between each fixing hole 17a and the corresponding screw hole 18a can be adjusted. This allows the height position of the retaining member 16 relative to the base member 17 to be adjusted. In other words, the height of the regulating member 12 can be adjusted.

[0051] In this case, when a recording medium with a long width (in the Y direction) is used as the recording medium, the holding member 16, the base member 17, and the height adjustment member 18 become longer in the Y direction according to the maximum size of the recording medium that the recording device 1 can handle. When these members become longer in the Y direction, the height of each regulating member 12 becomes unstable due to the curvature of the members. In this embodiment, by individually adjusting the relative position in the Z direction between each fixing hole 17a and the corresponding screw hole 18a, the curvature in the Y direction of the height adjustment member 18 and the holding member 16 can be adjusted, and the height of each regulating member 12 can be adjusted individually.

[0052] In this embodiment, the bending strength in the Y direction of the holding member 16, base member 17, and height adjustment member 18 is in the relationship base member 17 > height adjustment member 18 > holding member 16. Therefore, it is possible to fix the height adjustment member 18 to the base member 17 in a state aligned with the dashed lines M1 and M2 illustrated in Figure 11, and the holding member 16 also follows the curvature of the height adjustment member 18. curvedIt is possible to fix it in this state. In other words, by adjusting the curvature of the height adjustment member 18, variations in the height of individual regulating members 12 can be eliminated. In this way, it is possible to adjust the height of the regulating members 12 that suppress the floating of the recording medium.

[0053] <Controlling margins> If the leading edge of the roll sheet SH2 is significantly curled, the amount of excess material at the leading edge of the roll sheet SH2 may be controlled to more reliably prevent contact between the recording head 6 and the roll sheet SH2. This will be explained with reference to the examples in Figures 6(A) and 6(B).

[0054] If the tip of the roll sheet SH2 is significantly curled, recording will not begin when the tip of the roll sheet SH2 is positioned on the platen portion 80, as shown in Figure 6(A). Recording will begin when the tip of the roll sheet SH2 reaches the connection portion 83, as shown in Figure 6(B). This ensures that contact between the recording head 6 and the roll sheet SH2 during recording is prevented more reliably, even when the tip of the roll sheet SH2 is significantly curled.

[0055] Furthermore, the amount of margin at the front of the recording medium may be controlled based on information that the control unit 14 can recognize, such as the type of recording medium, the recording mode, the ambient temperature and humidity of the installation location of the recording device 1, and the remaining amount of roll sheet. For example, for recording mediums with a large curl, increasing the amount of margin allows recording to start when the front of the recording medium reaches a predetermined position in the X direction of the downward inclined section 84. This makes it possible to more reliably prevent contact between the recording head 6 and the roll sheet SH2 during recording.

[0056] Similarly, if the ambient temperature and humidity are lower than the expected temperature and humidity, or if there is little remaining roll sheet SH2, the curl at the leading edge of the recording medium tends to increase, so the margin may be increased before starting recording. Furthermore, if a recording mode that records at a low speed is executed, there will be more time for the recording medium to rise, so the margin may be increased.

[0057] If the margin at the leading edge of the recording medium is increased in this way, the cutting unit 5 may cut the leading edge of the recording medium, taking the increased margin into consideration.

[0058] <Other Embodiments> The present invention can also be realized by supplying a program that implements one or more of the functions of the above-described embodiments to a system or device via a network or storage medium, and by having one or more processors in the computer of that system or device read and execute the program.
