DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The present invention will first be briefly described below. In order to solve the above problem, a first aspect of a conveying device of the present invention comprises a conveying belt having a support surface for supporting media and capable of conveying the media, a wiper capable of wiping the support surface, a mounting portion to which the wiper is attached, and a pressing portion capable of switching between a pressing state in which the wiper is pressed against the mounting portion and a release state in which the pressure of the wiper against the mounting portion is released, wherein the wiper includes a base attached to the mounting portion, and at least one pin is provided on one of the base and the mounting portion, and a hole through which the at least one pin is inserted is provided on the other.

[0009] According to this aspect, at least one of the pins is provided on either the base or the mounting portion, and the pin is inserted into a hole provided on the other of the base and the mounting portion. As a result, the pin is caught in the hole, so that even if the pressing portion is released when replacing the wiper, the wiper is prevented from falling due to its own weight. This makes it possible to prevent a decrease in the workability of replacing the wiper.

[0010] A conveying device according to a second aspect of the present invention is characterized in that, in the first aspect, the pins include a first pin and a second pin inserted into one of the holes, the first pin and the second pin are provided on the mounting portion, the hole is provided on the base, and when the first pin and the second pin are inserted into the hole, the first pin and the second pin press the inner wall that constitutes the hole in different directions from each other.

[0011] According to this aspect, when the first pin and the second pin are inserted into the hole, the first pin and the second pin press the inner wall constituting the hole with pressing forces in different directions. This makes it possible to further prevent the wiper from falling due to its own weight even if the pressing portion is released when replacing the wiper. Therefore, it is possible to further prevent the workability of replacing the wiper from decreasing.

[0012] The transport device according to a third aspect of the present invention is the transport device according to the first or second aspect, characterized in that a portion of the pressing portion that contacts the base portion has projections and recesses.

[0013] When the pressing portion is switched to the released state, the wiper may stick to the pressing portion depending on the material of which the wiper is made. According to this aspect, the portion of the holding portion that contacts the base has an uneven surface, making it difficult for the wiper to adhere to the holding portion, and preventing the wiper from falling off the holding portion due to the adhesion.

[0014] A conveying device according to a fourth aspect of the present invention is characterized in that, in any one of the first to third aspects, the pressing portion comprises a slide portion that is slidable relative to the mounting portion, and a convex portion provided on a portion of the slide portion that faces the base, and the convex portion moves the base to a position where it can be pressed against the mounting portion by the sliding movement of the slide portion. According to this aspect, the user can press the base portion against the attachment portion by simply sliding the slide portion, thereby improving the workability of replacing the wiper.

[0015] The conveying device according to a fifth aspect of the present invention is the fourth aspect, characterized in that the slide portion is engaged with the mounting portion when it has slid the furthest relative to the mounting portion. According to this aspect, the slide portion is locked in a state where it has slid to the maximum extent relative to the mounting portion, so that the slide portion is less likely to fall off.

[0016] A sixth aspect of the present invention is characterized in that the conveying device of the fourth or fifth aspect is provided with a storage section in which a liquid for cleaning the support surface is stored, the mounting section is supported inside the storage section, and the sliding section includes a cover section that covers the at least one pin and the hole. According to this aspect, the liquid stored in the storage section adheres to the base, thereby preventing dirt from entering the gap between the pin and the hole, and thus preventing the wiper and the pin from becoming dirty.

[0017] A seventh aspect of the present invention is a conveying device according to the sixth aspect, characterized in that the cover has a first opening through which the wiper enters when sliding relative to the mounting portion, and a second opening positioned opposite the first opening in the direction of sliding relative to the mounting portion, and the second opening is positioned below the first opening in the direction of gravity. According to this aspect, the liquid used to clean the support surface flows along the wiper and into the reservoir through the second opening, thereby preventing the liquid from accumulating inside the cover, thereby preventing the inside of the cover from becoming dirty.

[0018] A transport device according to an eighth aspect of the present invention is any one of the first to seventh aspects, characterized in that the at least one pin is provided with a taper. According to this aspect, if the taper has a tapered shape, the pin can be easily inserted into the hole. Also, if the taper has a widened shape, the wiper can be further prevented from falling off the mounting portion due to its own weight.

[0019] A recording device according to a ninth aspect of the present invention comprises a recording unit capable of recording on media, and a transport device for transporting the media, the transport device having a support surface for supporting the media, a transport belt capable of transporting the media, a wiper capable of wiping the support surface, a mounting portion to which the wiper is attached, and a pressing portion capable of switching between a pressing state in which the wiper is pressed against the mounting portion and a release state in which the pressure of the wiper against the mounting portion is released, the wiper includes a base attached to the mounting portion, and at least one pin is provided on one of the base and the mounting portion, and a hole through which the at least one pin is inserted is provided on the other. According to this aspect, it is possible to obtain the same effects as the first aspect as a recording device.

[0020] [Embodiment 1] A recording apparatus including a conveying device according to a first embodiment of the present invention will be described in detail below with reference to FIGS. In the following description, the three mutually orthogonal axes are referred to as the X-axis, Y-axis, and Z-axis, as shown in each drawing. The Z-axis direction corresponds to the vertical direction (the direction in which gravity acts). The X-axis and Y-axis directions correspond to the horizontal direction. Here, the Y-axis direction corresponds to the transport direction of the medium, and the X-axis direction corresponds to the width direction of the medium that intersects with the transport direction.

[0021] As shown in Figure 1, the recording device 1 of this embodiment is an inkjet printer, and includes a recording unit 3 equipped with an ejection head that ejects ink onto a medium P transported in a transport direction (Y-axis direction) F, and a transport device 5 that transports the medium P. As shown in Figures 1 and 2, the conveying device 5 of this embodiment has a support surface 7 that supports the media P, and is equipped with a conveying belt 9 capable of conveying the media P, a wiper 11 that can wipe the support surface 7, an attachment portion 13 to which the wiper 11 is attached, and a pressing portion 15 that can be switched between a pressing state in which the wiper 11 is pressed against the attachment portion 13 and a release state in which the pressure of the wiper 11 against the attachment portion 13 is released. Furthermore, the wiper 11 includes a base 17 attached to the attachment portion 13. The attachment portion 13 has an attachment surface 13a that can come into contact with at least the base 17. Furthermore, at least one pin 19 is provided on one of the base 17 and the attachment portion 13, and at least one hole 21 through which the pin 19 is inserted is provided on the other. The number of holes 21 corresponds to the number of pins 19.

[0022] The conveying device 5 of this embodiment includes a wiping unit 2 that wipes the support surface 7 of the conveyor belt 9. The wiping unit 2 includes a wiper 11, an attachment unit 13, and a pressing unit 15 as basic elements. The wiping unit 2 is attached to the belt cleaning device 14. In this embodiment, the wiping unit 2 is attached in an inclined state with respect to the belt cleaning device 14. Specifically, the attachment surface 13a of the attachment portion 13 is inclined with respect to the Y-axis direction. As a result, when the wiper 11 is attached to the attachment portion 13, the wiper 11 is inclined with respect to the Y-axis direction. The belt cleaning device 14 has a storage portion 18 that stores the cleaning liquid 16, a brush roller 20, and a wiping unit 2, and is disposed in the vicinity of a drive roller 4 (to be described later) of the conveyor belt 9 as shown in FIG. 1. The wiping unit 2 is supported inside the storage portion 18. Specifically, the attachment portion 13 of the wiping unit 2 is fixed to the inner surface of the storage portion 18. When the conveyor belt 9 moves at the wiping unit 2, the support surface 7 is wiped by the wiper 11.

[0023] Each component of the transport device 5 will now be described. <Conveyor belt> As shown in FIG. 1, the conveyor belt 9 is an endless belt stretched over a drive roller 4 and a driven roller 6. An adhesive layer 8 is provided on a support surface 7, which is the outer peripheral surface of the endless conveyor belt 9. The media P is attached to the adhesive layer 8 by an attachment member (not shown), and passes through the recording unit 3 in this attached state. The attachment member is, for example, a pressing roller that presses the media P against the support surface 7. Ink is adhered to the support surface 7 of the conveyor belt 9 by the recording operation of the recording unit 3. A belt cleaning device 14 that cleans the support surface 7 to which the ink has adhered is disposed near the drive roller 4 as described above. The medium P is a normal sheet-like recording medium, such as paper, fabric, or plastic film, on which recording is performed by an inkjet printer.

[0024] <Wiper, hole> The wiper 11 is formed in a plate shape from a material having elasticity such as silicone rubber. As shown in FIG. 2 and FIG. 3, the wiper 11 includes a base 17 attached to the attachment portion 13, and a contact portion 10 located at the tip side of the base 17 for contacting the support surface 7 of the conveyor belt 9 to wipe the support surface 7. When a direction A is parallel to the attachment surface 13a and perpendicular to the X-axis direction, the length of the wiper 11 in the X-axis direction is greater than the length of the wiper 11 in the direction A. In this embodiment, the contact portion 10 is formed in a tapered shape when viewed from the side from the X-axis direction, but it is needless to say that the shape is not limited to this tapered shape. The length of the wiper 11 in the X-axis direction is the same as or slightly longer than the width dimension in the X-axis direction of the conveyor belt 9 to be wiped. In addition, the wiper may also be called a blade or a wiper blade in this technical field. In this embodiment, two circular holes 21, 21 penetrate the base 17 of the wiper 11. A pin 19 of the attachment portion 13, which will be described later, is inserted into these two holes 21, 21.

[0025] <Mounting part, pin> The mounting portion 13 is a portion to which the wiper 11 is attached, and in this embodiment, the mounting portion 13 is provided with two pins 19, 19. In this embodiment, the pins 19, 19 are cylindrical in shape, as shown in Figures 2, 3, and 4. Note that the pins 19, 19 are not limited to a cylindrical shape, and may be a prismatic shape or the like, and are not limited to a specific shape. 2, the length of the pins 19, 19 is formed to a dimension that allows them to pass through both the holes 21, 21 of the wiper 11 and the holes 12, 12 of the pressing portion 15, which will be described later. Note that the length of the pins 19, 19 only needs to reach at least the holes 21, 21 of the wiper 11, so they may not pass through the pressing portion 15. When the length of the pins 19, 19 is such that they do not pass through the pressing portion 15, the pressing portion 15 does not need to have holes 12, 12.

[0026] In this embodiment, a structure in which two pins 19, 19 are provided on the mounting portion 13 and two holes 21, 21 are provided on the base portion 17 of the wiper 11 is shown, but the present invention is not limited to this embodiment. For example, a structure in which two holes 21, 21 are provided on the mounting portion 13 and two pins 19, 19 are provided on the base portion 17 of the wiper 11 may be used. Note that the number of each of the pins 19 and the holes 21 is not limited to two, and may be at least one. In other words, the number of each of the pins 19 and the holes 21 may be one or three or more.

[0027] <Variations of pin> 3C, the pins 19, 19 may be provided with a taper 23. When the pins 19, 19 are cylindrical, the taper 23 is preferably frustum-shaped, and when the pins 19, 19 are prismatic, the taper 23 is preferably frustum-shaped. According to this modification, when the taper 23 has a tapered shape, it becomes easier to pass the pins 19, 19 through the holes 21, 21. Also, when the taper 23 has a widened shape, it becomes easier to prevent the pins 19, 19 from accidentally coming out of the holes 21, 21. This makes it possible to prevent the wiper 11 from falling off the attachment portion 13 due to its own weight.

[0028] <Pressing part> As described above, the pressing portion 15 is attached to the mounting portion 13 so as to be switchable between a pressing state in which the wiper 11 is pressed against the mounting portion 13 and a release state in which the pressure of the wiper 11 against the mounting portion 13 is released. In this embodiment, the pressing portion 15 is attached to the mounting portion 13 by a fastening member such as a screw (not shown). The pressing portion 15 is configured to realize the "pressing state" when attached to the mounting portion 13, and to realize the "released state" when the fastening member is removed. As shown in the meeting notice of Fig. 2 and Fig. 43, in this embodiment, the pressing portion 15 is provided with two holes 12, 12. As described above, the tip portions of the two pins 19, 19 provided on the mounting portion 13 are inserted into the two holes 12, 12 provided on the pressing portion 15 side. These two holes 12, 12 are formed to have approximately the same diameter as the pins 19, 19. That is, the pins 19, 19 are inserted into both the holes 21, 21 of the wiper 11 and the holes 12, 12 of the pressing portion 15.

[0029] In this embodiment, as shown in Figs. 6 and 7, the portion of the pressing portion 15 that contacts the base portion 17 has unevenness 25. The unevenness 25 includes, for example, a plurality of convex portions and a concave portion formed between two adjacent convex portions. The unevenness 25 is provided to reduce the contact area with the base portion 17 of the wiper 11 and suppress adhesion of the pressing portion 15 to the wiper 11. The convex portion of the unevenness 25 can contact a portion of the base portion 17 where the holes 21, 21 are not provided. Specific examples of the structure of the unevenness 25 include a structure formed of long grooves 22 and mountains 24 arranged in parallel as shown in Fig. 6, and a structure in which a plurality of hemispherical protrusions 26 are arranged vertically and horizontally as shown in Fig. 7.

[0030] <Explanation of the Function of the First Embodiment> Next, a case where the wiper 11 is replaced in the recording apparatus 1 having the transport device 5 of the first embodiment will be described with reference to FIGS. First, the wiper 11 of the wiping unit 2 is brought into a state where the worker can access it. Then, the fastening members are released to remove the pressing part 15 from the mounting part 13 (FIG. 3). This changes the wiper 11 from a state pressed by the pressing part 15 to a released state. Even in this released state, the pins 19, 19 of the mounting part 13 are inserted into the holes 21, 21 of the wiper 11. Therefore, the wiper 11 does not fall off the mounting part 13 inadvertently. The worker removes the wiper 11 from the pins 19, 19, and attaches a new wiper 11 to the attachment portion 13. That is, the new wiper 11 is attached by inserting the pins 19, 19 into the holes 21, 21 of the new wiper 11. In this state, the pressing portion 15 is attached to the attachment portion 13 by the fastening member. This completes the replacement work of the wiper 11.

[0031] <Explanation of Effects of First Embodiment> (1) According to this embodiment, at least one pin 19, 19 is provided on either the base 17 or the attachment portion 13 of the wiper 11, and the pin 19, 19 is inserted into a hole 21, 21 provided on the other. As a result, the pin 19, 19 is caught in the hole 21, 21, so that when replacing the wiper 11, even if the pressing portion 15 is in the released state, the wiper 11 can be prevented from falling due to its own weight. This makes it possible to prevent a decrease in the workability of replacing the wiper.

[0032] (2) When the pressing portion 15 is switched to the released state, the wiper 11 may stick to the pressing portion 15 depending on the material of the wiper 11. According to the present embodiment, the pressing portion 15 has the unevenness 25, and the convex portion of the unevenness 25 contacts the base portion 17. The unevenness 25 makes it possible to reduce the contact area between the pressing portion 15 and the base portion 17. This makes it difficult for the wiper 11 to stick to the pressing portion 15, and it is possible to prevent the wiper 11 from falling off the pressing portion 15 due to the adhesion. For example, it is possible to prevent the wiper 11 from falling off the pressing portion 15 after a predetermined time has elapsed after the user separates the pressing portion 15 from the attachment portion 13, and falling to a place not intended by the user.

[0033] The height of the convex portion of the unevenness 25 may be less than the thickness of the base 17 or may be equal to or greater than the thickness of the base 17. In the former case, even if the wiper 11 is in close contact with the mounting surface 13a when the pressing portion 15 is in a pressing state, if the wiper 11 is made of a material having elasticity, the convex portion is likely to sink into the wiper 11. This makes it possible to prevent the wiper 11 from floating up from the mounting surface 13a when the pressing portion 15 is in a pressing state. Therefore, it is possible to prevent a decrease in the gripping action of the wiper 11 by the mounting portion 13 and the pressing portion 15 due to the wiper 11 being less likely to be in close contact with the mounting surface 13a. In the latter case, even if the wiper 11 is made of a material having elasticity, the wiper 11 is likely to float up from the mounting surface 13a when the pressing portion 15 is in a pressing state. In this case, by adjusting the number of convex portions of the unevenness 25, it is possible to reduce the contact area between the mounting surface 13a and the base 17 while maintaining the gripping action of the wiper 11 by the mounting part 13 and the pressing part 15 at a desired level. As a result, even if the wiper 11 is made of a material such as butyl rubber, the wiper 11 is less likely to stick to the mounting surface 13a, and the wiper 11 can be easily removed from the mounting surface 13a.

[0034] [Embodiment 2] Next, a transfer device 5 according to a second embodiment of the present invention will be described in detail with reference to FIGS. In the conveying device 5 of this embodiment, the two pins 19, 19 are each composed of a first pin 27 and a second pin 29. That is, each pin 19 includes a first pin 27 and a second pin 29. A pair of the first pin 27 and the second pin 29 is inserted into each hole 21 of the two holes 21, 21. The configuration in which the first pin 27 and the second pin 29 are provided in the attachment portion 13 and the hole 21 is provided in the base portion 17 is the same as in the first embodiment. Furthermore, the pair of first pin 27 and second pin 29 are attached to the attachment portion 13 so that, when inserted into the hole 21, they press the inner wall of the hole 21 with pressing forces in different directions. Specifically, the pair of first pin 27 and second pin 29 are made of an elastic body such as resin. Also, the distance between the tips of the first pin 27 and the second pin 29 is set to be slightly larger than the inner diameter of the hole 21 so that the pressing force is generated. Therefore, the pressing force is generated by a first restoring force based on the elasticity of the first pin 27 and a second restoring force based on the elasticity of the second pin 29. For example, one of the pair of arrows in FIG. 5 represents the first restoring force, and the other represents the second restoring force in the opposite direction to the first restoring force. Here, "different directions" is not limited to opposite directions along a straight line connecting first pin 27 and second pin 29. For example, in Fig. 10, the direction of the arrow indicating the direction of the pressing force may be an up-down direction instead of the diagonal direction indicated by the arrow in Fig. 10. For example, "different directions" also includes a mode in which the lines of action of the first restoring force and the second restoring force are parallel to each other but do not coincide with each other, and a mode in which the lines of action of the first restoring force and the second restoring force intersect each other.

[0035] 8 shows a structure in which a first pin 27 and a second pin 29 are arranged spaced apart from each other in a direction A. The pressing force is in the direction of the arrow in FIG. 9 shows a structure in which a first pin 27 and a second pin 29 are arranged spaced apart from each other in the horizontal direction (X-axis direction). The pressing force is in the direction of the arrow in FIG. 9, that is, the horizontal direction. 10 shows a structure in which a first pin 27 and a second pin 29 are arranged at an angle and spaced from each other. The pressing force is in the direction of the arrow in FIG. Other configurations are the same as those of the first embodiment, so the same parts are denoted by the same reference numerals and the description thereof will be omitted. Also, the description of the same operations and effects as those of the first embodiment will be omitted.

[0036] <Explanation of Effects of the Second Embodiment> According to this embodiment, when the first pin 27 and the second pin 29 are inserted into the hole 21, the first pin 27 and the second pin 29 press the inner wall constituting the hole 21 with pressing forces in different directions. This makes it possible to further prevent the wiper 11 from falling due to its own weight even if the pressing portion 15 is released when replacing the wiper 11. Therefore, it is possible to further prevent the workability of replacing the wiper from decreasing.

[0037] [Embodiment 3] Next, a conveying device 5 according to a third embodiment of the present invention will be described in detail with reference to FIGS. In the conveying device 5 of this embodiment, the pressing part 15 includes a sliding part 35 that is slidable relative to the mounting part 13, and a protruding part 31 provided on a part of the sliding part 35 that faces the base part 17. The protruding part 31 is configured so that, as the sliding part 35 slides, it moves to a position where it can press the base part 17 against the mounting part 13. Here, the protruding part 31 is formed in a convex spherical shape, but is not limited to this convex spherical shape and may be, for example, a semi-cylindrical shape that is long in the width direction of the wiper 11.

[0038] 12, the sliding portion 35 includes a pair of rails 30, 30 parallel to the sliding direction. The mounting portion 13 also includes a pair of long grooves 32, 32 parallel to the sliding direction. The sliding portion 35 is configured so that the pair of rails 30, 30 fit into the pair of long grooves 32, 32 of the mounting portion 13 to slide.

[0039] Furthermore, in this embodiment, the sliding portion 35 is provided with a locking portion 33 for the mounting portion 13 so as to be locked to the mounting portion 13 when the sliding portion 35 has slid the furthest relative to the mounting portion 13 in the direction A. The locking portion 33 is provided at a position corresponding to the position at which the sliding portion 35 is locked to the mounting portion 13. The state in Fig. 11 corresponds to the state in which the sliding portion 35 has slid the furthest relative to the mounting portion 13, and the locking portion 33 is located at the locking position. The locking portion 33 in this embodiment is composed of a rotating piece, and can be moved between the locking position and the release position by rotation. Note that the above-mentioned rotating structure of the small piece of the locking portion 33 is one example, and is not limited to this, and it goes without saying that the locking portion 33 may have a snap fit structure that can be locked and released, etc.

[0040] Furthermore, in this embodiment, as described above, the belt cleaning device 14 includes the storage portion 18 in which the liquid 16 for cleaning the support surface 7 of the conveyor belt 9 is stored, and the attachment portion 13 is supported inside the storage portion 18. The slide portion 35 is configured to include a cover portion 37 that covers at least one of the pins 19, 19 and the holes 21, 21. 7, the cover 37 has a first opening 39 into which the wiper 11 enters when the wiper 11 slides relative to the mounting portion 13, and a second opening 41 located opposite to the first opening 39 in the direction of the wiper 11 sliding relative to the mounting portion 13. The second opening 41 is configured to be located below the first opening 39 in the direction of gravity.

[0041] <Explanation of Effects of the Third Embodiment> (1) According to this embodiment, when replacing the wiper 11, the user can press the base portion 17 against the attachment portion 13 simply by sliding the slide portion 35. This can improve the workability of replacing the wiper. (2) Furthermore, since the sliding portion 35 is locked in the state where it has slid to the maximum extent relative to the mounting portion 13, the sliding portion 35 is less likely to fall off.

[0042] (3) Furthermore, since the slide portion 35 includes a cover portion 37 that covers at least one of the pins 19,19 and the holes 21,21, the liquid 16 stored in the storage portion 18 adheres to the base 17, which prevents dirt from entering the gaps between the pins 19,19 and the holes 21,21, thereby preventing the wiper 11 and the pins 19,19 from becoming dirty.

[0043] (4) Furthermore, the cover 37 includes a first opening 39 through which the wiper 11 enters, and a second opening 41 located opposite the first opening 39, with the second opening 41 located below the first opening 39 in the direction of gravity. This allows the liquid 16 used to clean the support surface 7 to flow along the wiper 11 and into the reservoir 18 through the second opening 41, thereby preventing the liquid 16 from accumulating within the cover 37. This prevents the inside of the cover 37 from becoming dirty.

[0044] Other Embodiments The recording device 1 equipped with the conveying device 5 according to the embodiment of the present invention is basically configured as described above, but it is of course possible to modify or omit some parts of the configuration without departing from the gist of the present invention.

[0045] In the third embodiment, the "state where the slide portion 35 has slid the furthest relative to the mounting portion 13" is not limited to the position of the slide portion 35 shown in Fig. 11. That is, the slide portion 35 may be engaged with the mounting portion 13 in a state where it has slid the furthest relative to the mounting portion 13 in a direction opposite to the direction A. Also, the slide portion 35 may be engaged with the mounting portion 13 in a state where it has slid the furthest relative to the mounting portion 13 in a direction intersecting the direction A. In these cases, the extending direction of the pair of rails 30, 30 and the long grooves 32, 32 may be changed as appropriate depending on the design of the moving direction of the slide portion 35. Also, the position where the small piece of the engaging portion 33 is provided and the arrangement of the snap-fit ​​mechanism may be changed as appropriate. [Explanation of symbols]
