[0007] 1. First embodiment First, there will be described the configuration of the recording apparatus 1. The recording apparatus 1 of this embodiment is, for example, an inkjet printer. In each figure, the direction along the X axis is the depth direction of the recording device 1, the direction along the Y axis is the width direction of the recording device 1, and the direction along the Z axis is the height direction of the recording device 1. In this embodiment, the -X direction side of the recording device 1 is the front side of the device, and the +X direction side is the rear side of the device.

[0008] 1, the recording device 1 of this embodiment is configured as a multifunction device including a device main body 2 and a scanner unit 3. The device main body 2 includes a plurality of medium storage cassettes 4 that store media P. Each medium storage cassette 4 is removably attached to the front side of the device main body 2. The media P is, for example, paper such as plain paper, cardboard, or photo paper.

[0009] Between the scanner unit 3 and the medium storage cassette 4 in the device height direction in the device main body 2, there are provided a discharge section 7 that discharges the medium P recorded by a line head 9 (FIG. 2) serving as a recording section that performs recording by ejecting ink, which is an example of a liquid, and a medium mounting section 5 that mounts the medium P discharged from the discharge section 7. In addition, an operation section 6 is provided on the front side of the device main body 2. The operation section 6 is provided with a display means such as a liquid crystal panel. By operating the operation section 6, instructions for recording operations and image reading operations can be input to the recording device 1.

[0010] Next, the transport path 11 for the medium P in the recording apparatus 1 will be described. 2, the recording device 1 includes a transport path 11 for the medium P. The transport path 11 includes a feed path 14 that transports the medium P picked up from the medium storage cassette 4, a straight path 12 that is connected to the feed path 14 and includes a recording area A (see FIG. 3A) recorded by the line head 9, and a face-down discharge path 13 that transports the medium P from the straight path 12 to the discharge unit 7. The medium P is transported along the transport path 11 by a medium transport unit 10 (feed roller 17, separation roller pair 18, registration roller 19, belt transport unit 20, and transport roller pair 42).

[0011] The following describes the transportation of the medium P from the medium containing cassette 4 to the discharge section 7. The recording device 1 includes a switchback path 15 that branches off from the straight path 12 downstream of the line head 9, and a reversing path 16 that is connected to the switchback path 15 and reverses the first side (front side) and second side (back side) of the medium P and returns them to the straight path 12, and is configured to enable so-called double-sided recording, in which recording is performed on the second side after recording on the first side of the medium P. A description of the reversal of the medium P by the switchback path 15 and the reversing path 16 will be omitted.

[0012] A feed roller 17 and a pair of separation rollers 18 that separates a plurality of sheets of medium P into a single sheet are provided in the feed path 14 in this order along the transport direction of the medium P. The feed roller 17 is configured to be rotated by a drive source (not shown). The pair of separation rollers 18 is also called a retard roller, and includes a drive roller 18a that sends the medium P toward the straight path 12, and a driven roller 18b that nips the medium P between the drive roller 18a and the drive roller 18a to separate the medium P.

[0013] Of the multiple media P stored in the medium storage cassette 4, the topmost medium P is picked up by the feed roller 17 and transported downstream in the transport direction. At this time, the next and subsequent media P may also be transported together with the topmost medium P, but the topmost medium P and the next and subsequent media P are separated by the separation roller pair 18, and only the topmost medium P is sent to the feed path 14.

[0014] A registration roller 19 is provided downstream in the transport direction of the separation roller pair 18. The feeding path 14 and the straight path 12 are connected at the position of the registration roller 19. The straight path 12 is configured as a path extending linearly, and is provided with the registration roller 19, a belt transport unit 20, a static elimination unit 25, and a line head 9. The straight path 12 passes through a recording area A ( FIG. 3A ) formed by the line head 9, and extends upstream and downstream of the line head 9.

[0015] In this embodiment, the belt conveyor 20 is disposed in an area facing the head surface of the line head 9, and supports the side of the medium P opposite to the recording surface.

[0016] The line head 9 is disposed opposite the conveyor belt 21, and when the medium P is conveyed to a position opposite the line head 9 on the belt conveyor unit 20, it performs recording by ejecting ink as droplets onto the recording surface of the medium P. The line head 9 is a recording head in which nozzles that eject ink are provided to cover the entire width of the medium P, and is a recording head that can record across the entire width of the medium P without moving the medium P in the width direction. Although the recording device 1 of this embodiment is equipped with a line head 9, it may be a serial type recording head that is mounted on a carriage and moves back and forth in a direction intersecting the medium transport direction while ejecting liquid onto the medium P to perform recording.

[0017] The medium P transported on the straight path 12 is then sent to a face-down discharge path 13. The face-down discharge path 13 is a curved transport path 11 that is connected to the straight path 12, and is a path that sends the medium P that has been recorded on by the line head 9 so that it is discharged from the discharge section 7 with the recording surface facing down. The medium P that has entered the face-down discharge path 13 is transported by a plurality of transport roller pairs 42, discharged from the discharge section 7, and placed on the medium loading section 5 with the recording surface facing down.

[0018] 3A, the belt transport unit 20 according to this embodiment includes an endless transport belt 21 that attracts the medium P to a belt outer surface 21a, and at least two rollers around which the transport belt 21 is wound: an upstream drive roller 22, and a downstream driven roller 23 located downstream in the medium transport direction (in the +Y-axis direction in FIG. 3A) from the upstream drive roller 22. The transport belt 21 is disposed opposite the head surface of the line head 9.

[0019] In the belt conveying unit 20, the conveying belt 21 is driven by the upstream driving roller 22 being rotated by a driving source such as a motor, and the medium P is conveyed downstream in the medium conveying direction. At that time, the downstream driven roller 23 is rotated by the conveying belt 21 which is driven by the rotational drive of the upstream driving roller 22. The upstream driving roller 22 is driven to rotate around the drive shaft 22a.

[0020] The drive source of the belt conveying unit 20 is configured to be capable of rotating forward and reverse so as to move the conveying belt 21 in a circular motion in the forward direction (the +C direction in the double-headed arrow shown in FIG. 3A), which is the conveying direction in which the medium P is conveyed, and in the reverse direction (the -C direction in the double-headed arrow shown in FIG. 3A), which is the opposite direction.

[0021] The belt conveying unit 20 is configured to be switchable by a state switching unit (not shown) between a first state in which at least a part of the belt outer surface 21a is at recording position B (opposing position) by the line head 9, and a second state (indicated by a dashed line in FIG. 2) in which the belt outer surface 21a is farther away from the line head 9 than recording position B. In the first state, the line head 9 records on the medium P. On the other hand, in the second state, the line head 9 does not record on the medium P. At this time, for example, in order to maintain the recording performance of the line head 9, the line head 9 in the non-recording state is covered from the -Z direction side with a cap (not shown).

[0022] The recording device 1 includes a cleaning unit 70 that cleans the conveyor belt 21. The cleaning unit 70 includes a scraping unit 71 that scrapes off residues (e.g., paper powder, ink, etc.) adhering to the belt outer surface 21a of the conveyor belt 21. This removes the residues from the belt outer surface 21a. The detailed configuration of the cleaning unit 70 will be described later. The scraping unit 71 is provided upstream of the charging roller 24 in the movement direction of the conveyor belt 21.

[0023] In this embodiment, the conveying belt 21 is a belt that conveys the medium P by electrostatically adsorbing it to the belt outer surface 21a, and the belt conveying section 20 is provided with a charging roller 24 as an example of a charging section that charges the conveying belt 21, and a charge removal section 25 that removes the charge on the surface of the medium P conveyed by the conveying belt 21.

[0024] The charging roller 24 is provided upstream of the charge removing unit 25 in the moving direction of the conveyor belt 21, and is provided below the conveyor path 11 at a position facing the upstream drive roller 22, and is in contact with the belt outer surface 21a. When the upstream drive roller 22 and the downstream driven roller 23 rotate to drive the conveyor belt 21, the charged belt outer surface 21a after contact with the charging roller 24 becomes a path forming surface that forms the conveyor path 11. Therefore, the adsorptivity of the medium P to the conveyor belt 21 that forms the conveyor path 11 is improved, and the medium P can be more effectively attracted to the conveyor belt 21.

[0025] The static electricity removal unit 25 includes an endless static electricity removal belt 26 that is provided across the width direction (direction along the X-axis) of the medium P and rotates in the width direction. The static electricity removal belt 26 has brushes 26a protruding from the outside, and the portion of the static electricity removal belt 26 that faces the medium P on the conveyor belt 21 moves in the direction along the X-axis, which is the medium width direction. The brushes 26a of the static electricity removal belt 26 are pressed against the medium P, thereby removing electric charge from the surface of the medium P. By removing electric charge from the surface of the medium P, the adhesiveness of the medium P to the conveyor belt 21 can be increased.

[0026] Furthermore, the belt conveying section 20 includes a first backup plate 28a and a second backup plate 28b that support the conveying belt 21 from the inner surface side between the upstream driving roller 22 and the downstream driven roller 23. The first backup plate 28a is disposed opposite the charge removing section 25, and the second backup plate 28b is disposed opposite the cleaning section 70 (scraping section 71).

[0027] The recording device 1 includes a control unit 100 that controls various operations executed by the recording device 1. The control unit 100 includes a CPU, a memory, a control circuit, and an I / F (interface). The CPU is an arithmetic processing device. The memory is a storage device that secures an area for storing programs for the CPU or a working area, and has memory elements such as RAM and EEPROM. When recording data or the like is acquired from an external device such as an information processing terminal via the I / F, the CPU transmits control signals to each drive unit via the control circuit. This controls the medium transport unit 10, the line head 9, etc.

[0028] Here, when a plate-shaped blade is used to scrape off the residue (for example, calcium carbonate contained in paper powder) attached to the belt outer surface 21a of the conveyor belt 21, the blade scrapes off the residue and removes it from the conveyor belt 21. However, if time passes with the residue attached to the tip of the blade accumulated, a part of the residue solidifies. If the solidified residue comes into contact with the belt outer surface 21a of the conveyor belt 21, the conveyor belt 21 is locally damaged. Since the conveyor belt 21 of this embodiment is a belt that electrostatically attracts and conveys the medium P, if the belt outer surface 21a of the conveyor belt 21 is damaged by the solidified residue, the insulating layer and adhesive layer formed on the belt outer surface 21a are damaged, the charging function is reduced, and a conveying failure of the medium P occurs. In other words, the life of the conveyor belt 21 is shortened. In order to prevent the residue adhering to the plate-shaped blade from solidifying, it is possible to consider a configuration including a cleaning mechanism for removing the residue adhering to the tip of the blade, or a mechanism for moving the blade in contact with and away from the conveyor belt 21, but this would complicate the structure, and there is a concern that the recording device 1 would become larger. Therefore, the cleaning section 70 of the recording apparatus 1 of this embodiment is configured to be able to suppress the occurrence of the above-mentioned problems. The configuration of the cleaning section 70 of this embodiment will be described below.

[0029] The cleaning section 70 includes a scraping section 71 that comes into contact with the conveyor belt 21 and scrapes off any residue adhering to the outer belt surface 21 a of the conveyor belt 21 . The scraping portion 71 includes a sponge member 72. The sponge member 72 forms a block-shaped rectangular parallelepiped and is disposed extending in a direction along the X-axis. The sponge member 72 is disposed below the conveyor belt 21. The +Z direction end of the sponge member 72 has a contact portion 72a that contacts the belt outer surface 21a. The contact portion 72a forms a flat surface and comes into surface contact with the conveyor belt 21. The dimension of the sponge member 72 in the direction along the X-axis is equal to the dimension of the conveyor belt 21 in the direction along the X-axis. This makes it possible to scrape off residual matter from the entire width direction of the outer belt surface 21a of the conveyor belt 21.

[0030] The cleaning unit 70 includes a support portion 73 that supports the lower end of the sponge member 72, a pressing portion 75 that presses the support portion 73 upward, and a fixed member 77 that supports the pressing portion 75. The fixed member 77 is fixed at a constant distance from the second backup plate 28b. The pressing portion 75 is, for example, a coil spring. One end of the pressing portion 75 is connected to the support portion 73, and the other end is connected to the fixed member 77. The sponge member 72 supported by the support portion 73 is biased in the +Z direction by the pressing portion 75, and is pressed against the conveyor belt 21 with a substantially constant pressure over the entire longitudinal direction of the sponge member 72. This allows the contact portion 72a of the sponge member 72 to scrape off residues attached to the belt outer surface 21a. The pressing portion 75 causes the sponge member 72 to constantly contact the conveyor belt 21, thereby improving cleaning performance. Further, the support portion 73 has a recess 73a recessed downward, into which the lower end portion of the sponge member 72 fits. In addition to the lower end surface of the sponge member 72, the +Y direction side surface and the -Y direction side surface of the sponge member 72 are supported by the support portion 73. Therefore, even if the sponge member 72 abuts against the moving conveyor belt 21, the sponge member 72 does not come off the support portion 73, and the sponge member 72 can be abutted against the conveyor belt 21 in a stable state.

[0031] The sponge member 72 is a member whose contact portion 72a is scraped off when it comes into contact with the moving conveyor belt 21. That is, the sponge member 72 scrapes off residues on the conveyor belt 21 and the contact portion 72a that comes into contact with the conveyor belt 21 is scraped off. The sponge member 72 of this embodiment is a foamed melamine sponge made of melamine resin. The melamine sponge has a fine mesh structure. The melamine sponge is suitable for scraping off residual matter and for scraping the contact portion 72a that contacts the conveyor belt 21. The size of the sponge member 72 can be set appropriately. For example, it is set according to the period for periodic replacement of the conveyor belt 21. This makes it possible to reduce the frequency of maintenance of the sponge member 72.

[0032] Furthermore, the cleaning section 70 has a fixed position relative to the belt conveyor section 20 and moves with the state switching of the belt conveyor section 20. That is, as shown in Fig. 3B, when the conveyor belt 21 switches from the first state to the second state, the cleaning section 70 moves together with the conveyor belt 21. This makes it possible to prevent interference with the cleaning section 70 when the conveyor belt 21 switches its state.

[0033] As described above, according to this embodiment, by pressing the sponge member 72 of the scraping unit 71 against the conveyor belt 21, it is possible to scrape off the residue adhering to the conveyor belt 21. Furthermore, since the sponge member 72 abuts against the conveyor belt 21, the abutting portion 72a of the sponge member 72 is scraped off by friction with the conveyor belt 21. That is, the sponge member 72 scrapes off the residue adhering to the conveyor belt 21, and at the same time, it is scraped off and falls from the scraping unit 71 together with the scraped off residue. As a result, the residue scraped off from the conveyor belt 21 does not accumulate on the contact portion 72a of the sponge member 72. In other words, the residue does not adhere to the contact portion 72a of the sponge member 72 and solidify. Therefore, compared to removing the residue on the conveyor belt 21 with a blade, for example, damage to the conveyor belt caused by solidified residue is suppressed, and the life of the conveyor belt 21 can be extended. Furthermore, in a configuration in which residues on the conveying belt 21 are removed with a blade, the structure of the recording device 1 is simplified compared to a configuration in which a cleaning mechanism is provided to remove residues adhering to the tip of the blade, or a mechanism is provided to bring the blade into contact with and away from the conveying belt 21, and an increase in size of the recording device 1 can be prevented.

[0034] 2. Second embodiment Next, a second embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals and the duplicated description will be omitted. 4, the recording apparatus 1A of this embodiment includes a cleaning unit 80. The cleaning unit 80 has a scraping unit 81 that scrapes off residue from the conveyor belt 21.

[0035] The scraping unit 81 includes a roller 84 having a rotation shaft 84a, and a sponge member 82 is disposed on the circumferential surface of the roller 84. The sponge member 82 is disposed with a uniform thickness on the circumferential surface of the roller 84. The sponge member 82 and the roller 84 are fixed, and the sponge member 82 rotates together with the rotation of the roller 84. The sponge member 82 is a melamine sponge. The cleaning section 80 includes a pressing section 85 (e.g., a coil spring) and a fixed member 87 that supports the pressing section 85, and the roller 84 is pressed toward the conveyor belt 21 by the pressing section 85. The roller 84 is rotated in accordance with the circular movement of the conveyor belt 21. For this reason, the entire circumferential direction of the sponge member 82 arranged on the roller 84 can become the abutment section 82a. As a result, the roller 84 can rotate and scrape off the residue on the conveyor belt 21 as the conveyor belt 21 moves around. In addition, the sponge member 82 is evenly scraped by the rotation of the roller 84, so that the durability (lifespan) of the sponge member 82 can be improved compared to a configuration in which the sponge member 82 is fixed and in contact with the conveyor belt 21.

[0036] Furthermore, in the recording apparatus 1A of the present embodiment, a speed difference is provided between the circumferential speed of the conveyor belt 21 and the circumferential speed of the roller 84. This makes it easier to scrape off residual matter from the conveyor belt 21 due to the speed difference between the conveyor belt 21 and the roller 84. Specifically, a torque limiter 86 is connected to the rotating shaft 84a. The torque limiter 86 applies a load to the rotation of the rotating shaft 84a, and a speed difference can be easily generated between the conveyor belt 21 and the roller 84.

[0037] As described above, according to this embodiment, when the conveyor belt 21 is rotated in the +C direction, the roller 84 rotates clockwise, and the conveyor belt 21 and the roller 84 rotate together. Then, the torque limiter 86 operates on the roller 84, so that a load is applied to the rotating shaft 84a, and the peripheral speed of the roller 84 becomes slower than the peripheral speed of the conveyor belt 21 (a speed difference occurs). This increases the friction between the conveyor belt 21 and the contact portion 82a of the sponge member 82, and the cleaning performance can be improved. In addition, since the sponge member 82 contacts the conveyor belt 21 while rotating, the durability (lifespan) of the sponge member 82 can be improved. Note that the residue scraped off by the sponge member 82 is discharged from the contact portion 82a in the -Y direction by the rotation of the roller 84, and falls from the scraping portion 81.

[0038] 3. Third embodiment Next, a third embodiment will be described. Note that the same components as those in the first embodiment are given the same reference numerals and the duplicated description will be omitted. 5A and 5B, the recording apparatus 1B of this embodiment includes a cleaning unit 90. The cleaning unit 90 has a scraping unit 91 that scrapes off residue from the conveyor belt 21.

[0039] The scraping unit 91 includes a roller 94 having a rotation shaft 94a, and a sponge member 92 is disposed on the circumferential surface of the roller 94. The sponge member 92 is disposed with a uniform thickness on the circumferential surface of the roller 94. The sponge member 92 and the roller 94 are fixed. The sponge member 92 is a melamine sponge. The cleaning unit 90 includes a pressing unit 95 (eg, a coil spring) and a fixed member 97 that supports the pressing unit 95. The pressing unit 95 presses the roller 94 toward the conveyor belt 21.

[0040] Furthermore, in the recording apparatus 1B of this embodiment, a speed difference is provided between the peripheral speed of the transport belt 21 and the peripheral speed of the roller 94. Specifically, a one-way clutch 96 is connected to the rotary shaft 94a. The one-way clutch 96 has a mechanism that does not rotate the roller 94 in one direction around the rotary shaft 94a, but rotates the roller 94 in the other direction around the rotary shaft 94a.

[0041] In this embodiment, as shown in Fig. 5A, when the conveyor belt 21 rotates in the conveying direction of the medium P (circular movement in the +C direction), the roller 94 does not rotate. On the other hand, as shown in Fig. 5B, when the conveyor belt 21 rotates in the opposite direction to the conveying direction of the medium P (circular movement in the -C direction), the roller 94 rotates following the conveyor belt 21.

[0042] As described above, according to this embodiment, when the conveyor belt 21 rotates in the counterclockwise direction, the roller 94 does not rotate due to the one-way clutch 96, so that a speed difference occurs between the peripheral speed of the conveyor belt 21 and the peripheral speed of the roller 94. Therefore, the sponge member 92 is fixed, and friction increases at the contact portion 92a, so that the cleaning performance on the conveyor belt 21 can be improved. On the other hand, when the conveyor belt 21 rotates in the clockwise direction, the roller 94 rotates (counterclockwise). As the roller 94 rotates, the residue attached to the contact portion 92a of the sponge member 92 can be dropped from the sponge member 92. In FIG. 5B, the residue is discharged from the contact portion 92a in the +Y direction and dropped from the scraping portion 91. Thereafter, when the conveyor belt 21 rotates again in the counterclockwise direction, the roller 94 stops rotating. At this time, a new surface of the sponge member 92 can become the abutment portion 92a, so that the durability (lifespan) of the sponge member 92 can be improved compared to a configuration in which the sponge member 92 is fixed and abuts against the conveyor belt 21.
