Yes. The recording head 30 has an ink ejection surface with a nozzle opened on its lower surface, and the ink ejection surface faces the surface of the transfer body 2 with a minute gap (for example, several mm). In the case of this embodiment, since the transfer body 2 is configured to cyclically move on a circular orbit, the plurality of recording heads 30 are arranged radially.

  Each nozzle is provided with an ejection element. The ejection element is, for example, an element that generates pressure in the nozzle and ejects ink in the nozzle, and an inkjet head technique of a known inkjet printer is applicable. As an ejection element, for example, an element that ejects ink by causing film boiling in the ink by an electrothermal transducer and forming bubbles, an element that ejects ink by an electromechanical transducer (piezo element), or using static electricity Examples include an element that ejects ink. From the viewpoint of high-speed and high-density recording, an ejection element using an electrothermal transducer can be used.

  In the present embodiment, nine recording heads 30 are provided. Each recording head 30 ejects different types of ink. The different types of ink are, for example, inks having different color materials, such as yellow ink, magenta ink, cyan ink, and black ink. One recording head 30 ejects one type of ink, but one recording head 30 may eject a plurality of types of ink. When a plurality of recording heads 30 are provided as described above, ink (for example, clear ink) in which some of them do not contain a color material may be ejected.

  The carriage 31 supports a plurality of recording heads 30. Each recording head 30 has an end on the ink ejection surface side fixed to a carriage 31. As a result, the gap between the ink discharge surface and the surface of the transfer body 2 can be maintained more precisely. The carriage 31 is configured to be displaceable while mounting the recording head 30 by the guidance of the guide member RL. In the case of the present embodiment, the guide members RL are rail members that extend in the Y direction, and a pair of guide members RL are provided apart from each other in the X direction. A slide portion 32 is provided on each side portion of the carriage 31 in the X direction. The slide part 32 engages with the guide member RL and slides in the Y direction along the guide member RL.

Recovery processing can be executed.

<Transfer unit>
The transfer unit 4 will be described with reference to FIG. The transfer unit 4 includes a transfer cylinder 41 and an impression cylinder 42. These cylinders are rotating bodies that rotate around a rotation axis in the Y direction, and have a cylindrical outer peripheral surface. In FIG. 1, the arrows shown in each figure of the transfer cylinder 41 and the impression cylinder 42 indicate the rotation directions of the transfer cylinder 41 and the impression cylinder 42 rotate clockwise and the impression cylinder 42 rotate counterclockwise.

  The transfer cylinder 41 is a support that supports the transfer body 2 on its outer peripheral surface. The transfer body 2 is provided on the outer peripheral surface of the transfer cylinder 41 continuously or intermittently in the circumferential direction. When continuously provided, the transfer body 2 is formed in an endless belt shape. When the transfer body 2 is provided intermittently, the transfer body 2 is formed into a plurality of segments in the form of a band with ends, and each segment can be arranged on the outer peripheral surface of the transfer cylinder 41 in an arc shape at an equal pitch.

  As the transfer cylinder 41 rotates, the transfer body 2 moves cyclically on the circular orbit. Depending on the rotational phase of the transfer cylinder 41, the position of the transfer body 2 can be distinguished into a pre-discharge processing region R1, a discharge region R2, post-discharge processing regions R3 and R4, a transfer region R5, and a post-transfer processing region R6. The transfer body 2 passes through these regions cyclically.

  The pre-ejection processing region R1 is a region where pre-processing is performed on the transfer body 2 before ink is ejected by the recording unit 3, and is a region where processing by the peripheral unit 5A is performed. In the case of this embodiment, a reaction solution is applied. The ejection region R2 is a formation region where the recording unit 3 ejects ink onto the transfer body 2 to form an ink image. The post-ejection processing regions R3 and R4 are processing regions for processing the ink image after ink ejection, the post-ejection processing region R3 is a region where processing is performed by the peripheral unit 5B, and the post-ejection processing region R4 is the peripheral unit 5C. This is the area where processing is performed. The transfer region R5 is a region where the ink image on the transfer body 2 is transferred to the recording medium P by the transfer unit 4. The post-transfer processing region R6 is a region where post-processing is performed on the transfer body 2 after transfer, and is a region where processing by the peripheral unit 5D is performed.

  In the case of the present embodiment, the ejection region R2 is a region having a certain section. The other regions R1, R3 to R6 are narrower than the discharge region R2. In the case of the present embodiment, in the case of this embodiment, the pre-discharge processing region R1 is approximately at 10 o'clock, the discharge region R2 is approximately from 11:00 to 1 o'clock, and the post-discharge processing region R3 is approximately It is the 2 o'clock position, and the post-discharge processing region R4 is approximately the 4 o'clock position. The transfer region R5 is approximately 6 o'clock and the post-transfer processing region R6 is approximately 8 o'clock.

  The transfer body 2 may be composed of a single layer, but may be a multi-layer laminate. When comprised by multiple layers, you may include the three layers of a surface layer, an elastic layer, and a compression layer, for example. The surface layer is an outermost layer having an image forming surface on which an ink image is formed. By providing the compression layer, the compression layer absorbs deformation, disperses the fluctuations with respect to local pressure fluctuations, and can maintain transferability even during high-speed recording. The elastic layer is a layer between the surface layer and the compression layer.

  As a material for the surface layer, various materials such as a resin and a ceramic can be used as appropriate, but a material having a high compression elastic modulus can be used in terms of durability and the like. Specific examples include condensates obtained by condensing acrylic resins, acrylic silicone resins, fluorine-containing resins, and hydrolyzable organosilicon compounds. The surface layer may be used after being subjected to a surface treatment in order to improve the wettability of the reaction solution, the image transferability, and the like. Examples of the surface treatment include flame treatment, corona treatment, plasma treatment, polishing treatment, roughening treatment, active energy ray irradiation treatment, ozone treatment, surfactant treatment, and silane coupling treatment. A plurality of these may be combined. Moreover, arbitrary surface shapes can also be provided in the surface layer.

  Examples of the material for the compression layer include acrylonitrile-butadiene rubber, acrylic rubber, chloroprene rubber, urethane rubber, and silicone rubber. At the time of molding such a rubber material, a predetermined amount of a vulcanizing agent, a vulcanization accelerator and the like are blended, and further a filler such as a foaming agent, hollow fine particles or salt is blended as necessary, and a porous rubber material It is good. Thereby, since the bubble part is compressed with a volume change with respect to various pressure fluctuations, deformation in the direction other than the compression direction is small, and more stable transferability and durability can be obtained. There are two types of porous rubber materials: one with a continuous pore structure in which each pore is continuous and the other with an independent pore structure in which each pore is independent. May be.

  As the member of the elastic layer, various materials such as resin and ceramic can be used as appropriate. Various elastomer materials and rubber materials can be used in terms of processing characteristics. Specific examples include fluorosilicone rubber, phenylsilicone rubber, fluororubber, chloroprene rubber, urethane rubber, and nitrile rubber. Further, ethylene propylene rubber, natural rubber, styrene rubber, isoprene rubber, butadiene rubber, ethylene / propylene / butadiene copolymer, nitrile butadiene rubber and the like can be mentioned. In particular, silicone rubber, fluorosilicone rubber, and phenyl silicone rubber are advantageous in terms of dimensional stability and durability because they have a small compression set. Further, the change in elastic modulus with temperature is small, which is advantageous in terms of transferability.

  Various adhesives and double-sided tapes can be used between the surface layer and the elastic layer and between the elastic layer and the compression layer in order to fix them. Further, the transfer body 2 may include a reinforcing layer having a high compression elastic modulus in order to suppress lateral elongation when the transfer body 2 is mounted on the transfer cylinder 41 and to maintain stiffness. A woven fabric may be used as the reinforcing layer. The transfer body 2 can be produced by arbitrarily combining the layers made of the above materials.

  The outer surface of the pressure drum 42 is pressed against the transfer body 2. At least one grip mechanism for holding the tip of the recording medium P is provided on the outer peripheral surface of the impression cylinder 42. A plurality of grip mechanisms may be provided apart from each other in the circumferential direction of the impression cylinder 42. The recording medium P is conveyed in close contact with the outer peripheral surface of the impression cylinder 42, and when passing through the nip portion between the impression cylinder 42 and the transfer body 2, the ink image on the transfer body 2 is transferred.

  A driving source such as a motor for driving the transfer cylinder 41 and the impression cylinder 42 is common to these, and the driving force can be distributed by a transmission mechanism such as a gear mechanism.

<Peripheral unit>
The peripheral units 5 </ b> A to 5 </ b> D are arranged around the transfer cylinder 41. In the case of this embodiment, the peripheral units 5A to 5D are, in order, an application unit, an absorption unit, a heating unit, and a cleaning unit.

  The applying unit 5 </ b> A is a mechanism that applies a reaction liquid onto the transfer body 2 before ink is discharged by the recording unit 3. The reaction liquid is a liquid containing a component that increases the viscosity of the ink. Here, increasing the viscosity of the ink means that the color material, resin, or the like constituting the ink chemically reacts or physically adsorbs by coming into contact with a component that increases the viscosity of the ink. An increase in the viscosity of the ink is observed. The increase in viscosity of this ink is not only when an increase in the viscosity of the entire ink is observed, but also when the viscosity increases locally due to agglomeration of some of the components constituting the ink, such as coloring materials and resins. Is also included.

  There are no particular restrictions on the components that increase the viscosity of the ink, such as metal ions and polymer flocculants, but substances that cause the pH change of the ink and cause the colorant in the ink to aggregate can be used. Can be used. Examples of the reaction liquid application mechanism include a roller, a recording head, a die coating apparatus (die coater), a blade coating apparatus (blade coater), and the like. If the reaction liquid is applied to the transfer body 2 before the ink is discharged onto the transfer body 2, the ink reaching the transfer body 2 can be immediately fixed. Thereby, the bleeding which the adjacent inks mix can be suppressed.

  The absorption unit 5B is a mechanism that absorbs the liquid component from the ink image on the transfer body 2 before transfer. By reducing the liquid component of the ink image, bleeding or the like of the image recorded on the recording medium P can be suppressed. If the reduction of the liquid component is described from a different viewpoint, it can be expressed that the ink constituting the ink image on the transfer body 2 is concentrated. Concentrating the ink means that the content ratio of the solid component such as a coloring material or resin contained in the ink increases as the liquid component contained in the ink decreases.

  The absorption unit 5B includes, for example, a liquid absorption member that contacts the ink image and reduces the amount of the liquid component of the ink image. The liquid absorbing member may be formed on the outer peripheral surface of the roller, or the liquid absorbing member may be formed in an endless sheet shape and run cyclically. From the viewpoint of protecting the ink image, the liquid absorbing member may be moved in synchronism with the transfer body 2 by making the moving speed of the liquid absorbing member the same as the peripheral speed of the transfer body 2.

  The liquid absorbing member may include a porous body that contacts the ink image. In order to suppress ink solid matter adhesion to the liquid absorbing member, the pore diameter of the porous body on the surface in contact with the ink image may be 10 μm or less. Here, the pore diameter means an average diameter, which can be measured by a known means such as a mercury intrusion method, a nitrogen adsorption method, or an SEM image observation. The liquid component is not particularly limited as long as it does not have a certain shape, has fluidity, and has a substantially constant volume. For example, water or an organic solvent contained in the ink or the reaction liquid can be used as the liquid component.

  The heating unit 5C is a mechanism for heating the ink image on the transfer body 2 before transfer. By heating the ink image, the resin in the ink image is melted and the transferability to the recording medium P is improved. The heating temperature can be higher than the minimum film-forming temperature (MFT) of the resin. The MFT can be measured by a generally known method, for example, each device conforming to JIS K 6828-2: 2003 or ISO 2115: 1996. From the viewpoint of transferability and image fastness, the film may be heated at a temperature 10 ° C. or higher than MFT, and further heated at a temperature 20 ° C. or higher. As the heating unit 5C, for example, a known heating device such as various lamps such as infrared rays or a hot air fan can be used. An infrared heater can be used in terms of heating efficiency.

  The cleaning unit 5D is a mechanism for cleaning the transfer body 2 after transfer. The cleaning unit 5D removes ink remaining on the transfer body 2, dust on the transfer body 2, and the like. For the cleaning unit 5D, for example, a known method such as a method of bringing a porous member into contact with the transfer member 2, a method of rubbing the surface of the transfer member 2 with a brush, or a method of scraping the surface of the transfer member 2 with a blade is appropriately used. Can do. Moreover, the well-known shape, such as a roller shape and a web shape, can be used for the cleaning member used for cleaning.

  As described above, in the present embodiment, the providing unit 5A, the absorption unit 5B, the heating unit 5C, and the cleaning unit 5D are provided as peripheral units. However, a cooling function of the transfer body 2 is provided to some of these units, or A cooling unit may be added. In the present embodiment, the temperature of the transfer body 2 may increase due to the heat of the heating unit 5C. If the ink image exceeds the boiling point of water, which is the main solvent of the ink, after the ink is ejected onto the transfer body 2 by the recording unit 3, the absorption performance of the liquid component by the absorption unit 5B may deteriorate. By cooling the transfer body 2 so that the ejected ink is maintained below the boiling point of water, the liquid component absorption performance can be maintained.

  The cooling unit may be a blower mechanism that blows air to the transfer body 2 or a mechanism that brings a member (for example, a roller) into contact with the transfer body 2 and cools the member by air cooling or water cooling. Moreover, the mechanism which cools the cleaning member of cleaning unit 5D may be sufficient. The cooling timing may be a period from after transfer to before application of the reaction solution.

<Supply unit>

<Operation example>
FIG. 6 is a diagram schematically showing an example of the recording operation. While the transfer cylinder 41 and the impression cylinder 42 are rotated, the following steps are performed cyclically. As shown in state ST1, first, the reaction liquid L is applied onto the transfer body 2 from the applying unit 5A. The portion of the transfer body 2 to which the reaction liquid L is applied moves as the transfer cylinder 41 rotates. When the portion to which the reaction liquid L is applied reaches below the recording head 30, ink is ejected from the recording head 30 to the transfer body 2 as shown in a state ST2. Thereby, an ink image IM is formed. At this time, the discharged ink mixes with the reaction liquid L on the transfer body 2, thereby aggregating the color material. The ejected ink is supplied from the storage unit TK of the supply unit 6 to the recording head 30.

  The ink image IM on the transfer body 2 moves as the transfer body 2 rotates. When the ink image IM reaches the absorption unit 5B, the liquid component is absorbed from the ink image IM by the absorption unit 5B as shown in the state ST3. When the ink image IM reaches the heating unit 5C, as shown in the state ST4, the ink image IM is heated by the heating unit 5C, the resin in the ink image IM is melted, and the ink image IM is formed. In synchronization with the formation of the ink image IM, the recording medium P is transported by the transport device 1B.

  As shown in the state ST5, the ink image IM and the recording medium P reach the nip portion between the transfer body 2 and the impression cylinder 42, the ink image IM is transferred to the recording medium P, and the recorded matter P ′ is manufactured. . After passing through the nip portion, the image recorded on the recorded material P ′ is taken by the inspection unit 9A, and the recorded image is inspected. The recorded matter P ′ is transported to the collection unit 8d by the transport device 1B.

  When the ink image IM formed on the transfer body 2 reaches the cleaning unit 5D, it is cleaned by the cleaning unit 5D as shown in the state ST6. After the cleaning, the transfer body 2 is rotated once, and the transfer of the ink image onto the recording medium P is repeatedly performed in the same procedure. In the above description, for ease of understanding, it has been described that the transfer of the ink image IM to one recording medium P is performed once with one rotation of the transfer body 2, but with one rotation of the transfer body 2. The ink image IM can be continuously transferred to a plurality of recording media P.

  If such a recording operation is continued, maintenance of each recording head 30 is required.

  FIG. 7 shows an example of operation during maintenance of each recording head 30. The state ST11 shows a state where the recording unit 3 is located at the discharge position POS1. State ST12 shows a state in which the recording unit 3 has passed the preliminary recovery position POS2, and processing for recovering the ejection performance of each recording head 30 of the recording unit 3 is executed by the recovery unit 12 during the passage. Thereafter, as shown in state ST13, the recovery unit 12 performs a process of recovering the ejection performance of each recording head 30 in a state where the recording unit 3 is positioned at the recovery position POS3.

  Next, in the recording system configured as described above, a method for cleaning the pressure drum 42 that nips the recording medium paired with the transfer body when the image formed on the transfer body is transferred to the recording medium will be described. .

  As described above, after transferring the image to the recording medium P, the transfer body 2 is further rotated and the surface of the transferred transfer body is cleaned by the cleaning unit 5D. However, the ink also adheres to the pressure drum 42 as a pair. Or dust may adhere. For this reason, in this embodiment, an impression cylinder cleaning unit for cleaning the impression cylinder and removing deposits such as dust and ink is provided, so that the surface of the impression cylinder can be regularly maintained in a clean state. ing.

<Detailed description of the impression cylinder cleaning unit 43>
FIG. 8 is a diagram for explaining the configuration and operation of the impression cylinder cleaning unit 43.

  The impression cylinder cleaning unit 43 is a mechanism that cleans the surface of the impression cylinder 42 after image transfer, and removes ink, dust, and the like remaining on the impression cylinder surface. The impression cylinder cleaning unit 43 is provided below the impression cylinder 42 of the transfer unit 4 and is configured to immediately clean a portion of the impression cylinder from which the nip with the transfer body 2 has been eliminated. Therefore, before the part of the impression cylinder 42 rotates to form the nip with the transport cylinder 8a, the part is cleaned. This prevents the contaminated portion of the impression cylinder 42 from forming a nip with the conveying cylinder 8a as it is, thereby preventing the contamination from spreading.

  As shown in FIGS. 8A to 8C, the impression cylinder cleaning unit 43 includes a cleaning roller 43A, a cleaning blade 43B, and a guide roller 43C. The cleaning roller 43A contacts the pressure drum 42 and cleans the surface of the pressure drum. The cleaning roller 43A is attached to the tip of a roller support 43F that rotates about a rotation shaft 43D, and the surface of an object (for example, an impression cylinder) that is contacted by the rotation of the cleaning roller 43A itself. Clean. The rotation shaft 43D is provided at the end opposite to the tip of the roller support 43F. The rotation may be a rotation by a drive motor (not shown), or may be a rotation driven by the rotation of the impression cylinder 42 when in contact with the impression cylinder.

  The cleaning blade 43B is disposed downstream of the cleaning roller 43A with respect to the rotation direction of the impression cylinder 42. The guide roller 43C is disposed upstream of the cleaning roller 43A in the rotation direction of the impression cylinder 42, and presses the recording medium so that it does not float when the recording medium after image transfer held on the impression cylinder surface is conveyed. . Although not shown in FIG. 8, a cleaning roller rotating portion is provided for rotating the rotating roller 43A around the rotation shaft 43D so that the cleaning roller 43A can contact and separate from the impression cylinder 42. Further, the cleaning blade 43B is provided with a cleaning blade rotating portion for rotating around the rotation shaft 43E so that the cleaning blade 43B can be brought into contact with and separated from the impression cylinder 42.

  The pressure drum cleaning unit 43 is not limited to a configuration built in the transfer unit 4 but may be a configuration added as an option to the transfer unit 4.

  Next, the cleaning operation of the impression cylinder cleaning unit 43 will be described.

  The impression cylinder cleaning unit 43 has the following three cleaning modes. That is, a first mode for cleaning the surface of the impression cylinder 42 (first operation), a second mode for cleaning the cleaning blade 43B (second operation mode), and a third mode for cleaning the guide roller 43C (second operation mode). (Third operation mode). These modes are switched and controlled by the main controller 13A via the transport control unit 15D.

First Mode As shown in FIG. 8A, in the first mode, the cleaning roller rotating unit and the cleaning blade rotating unit are operated to clean the surface of the impression cylinder 42, and the cleaning roller 43A is operated. The cleaning blade 43B is arranged so as to be in contact with the surface of the impression cylinder 42. In this state, the surface of the impression cylinder is cleaned by rotating the impression cylinder 42.

Second Mode As shown in FIG. 8B, in the second mode, the cleaning roller rotating unit and the cleaning blade rotating unit are operated to clean the cleaning blade 43B, and the cleaning roller 43A and the cleaning mode are cleaned. The blades 43B are positioned so as to contact each other. The dirt attached to the cleaning blade 43B is cleaned by rotating the cleaning roller 43A while the cleaning roller 43A and the cleaning blade 43B are in contact with each other.

Third Mode As shown in FIG. 8C, in the third mode, the cleaning roller rotating portion is operated to clean the guide roller 43C so that the cleaning roller 43A comes into contact with the guide roller 43C. To be. In this state, the dirt attached to the guide roller 43C is cleaned by rotating the cleaning roller 43A.

  While appropriately switching the above three modes by performing the following control, the pressure drum, the cleaning blade and the guide roller provided around it are also cleaned.

  FIG. 9 is a flowchart showing a cleaning process executed by the impression cylinder cleaning unit.

  First, in step S10, the operation mode of the impression cylinder cleaning unit is determined. This determination is made by the main controller 13A based on, for example, the elapsed time since the previous cleaning of the impression cylinder, the number of recordings on the recording medium, the ink consumption for image formation, and the like. If the operation mode is the first mode, the process proceeds to step S20.

  In step S20, it is checked whether or not the recording medium on which the image has been transferred is passing through the contact point between the cleaning roller 43A and the impression cylinder 42, and the processing is waited until the passage is completed. For example, when the recording on the recording medium is single-sided, the recording medium is transported to the transport cylinder 8 on the downstream side in the transport direction, so that the waiting time is also from the transport mechanism shown in FIG. Absent. On the other hand, when recording on the recording medium is performed on both sides, the recording medium is conveyed by the impression cylinder 42 and further conveyed by the conveyance cylinder 8a, so that the recording medium is cleaned with the cleaning roller 43A and the impression cylinder 42. Since it takes time to pass through the contact point, waiting is required. In any case, if it is confirmed that the recording medium has not passed through the contact point between the cleaning roller 43A and the impression cylinder 42, the process proceeds to step S30.

  In step S30, the cleaning roller 43A and the cleaning blade 43B are brought into contact with the surface of the impression cylinder 42 as shown in FIG. Further, due to the contact, in step S40, the cleaning roller 43A is driven to rotate along with the rotation of the impression cylinder 42 to clean the surface of the impression cylinder 42, and the cleaning blade 43B removes dust and adhered ink on the impression cylinder surface. Scratch. In step S50, it is determined whether or not the cleaning is to be ended. If the cleaning is continued, the process returns to step S40. If the cleaning is to be ended, the process proceeds to step S60.

  In step S60, the cleaning roller 43A and the cleaning blade 43B are separated from the surface of the impression cylinder 42. Thereafter, the process ends.

  In step S10, when the operation mode is the second mode, the process proceeds to step S70. In step S70, the cleaning roller rotating unit and the cleaning blade rotating unit are operated so that the cleaning roller 43A and the cleaning blade 43B come into contact with each other as shown in FIG. 8B. In step S80, the cleaning roller 43A is rotated by the drive motor. Thereby, the cleaning blade 43B is cleaned. In step S90, it is determined whether or not the cleaning is to be finished. If the cleaning is continued, the process returns to step S80. If the cleaning is to be finished, the process proceeds to step S100.

  In step S100, the rotation of the cleaning roller 43A is stopped, the cleaning roller rotating unit and the cleaning blade rotating unit are operated, and the cleaning roller 43A and the cleaning blade 43B are separated from each other. Thereafter, the process ends.

  In step S10, when the operation mode is the third mode, the process proceeds to step S110. In step S110, the cleaning roller rotating unit is operated so that the cleaning roller 43A comes into contact with the guide roller 43C as shown in FIG. 8C. In step S120, dirt attached to the guide roller 43C is cleaned by rotating the cleaning roller 43A in this state. In step S130, it is determined whether or not the cleaning is to be finished. If the cleaning is continued, the process returns to step S120. If the cleaning is to be finished, the process proceeds to step S140.

  In step S140, the rotation of the cleaning roller 43A is stopped, the cleaning roller rotating unit is operated, and the cleaning roller 43A is separated from the guide roller 43C. Thereafter, the process ends.

  Therefore, according to the embodiment described above, the operation mode of the impression cylinder cleaning unit is switched to operate not only to clean the impression cylinder, which is a rotating body, but also to the cleaning blade and guide roller provided in the vicinity thereof. Can also be cleaned.

  In the above-described embodiment, the cleaning unit for the impression cylinder that forms the nip with the transfer member has been described. However, the present invention is not limited thereto. For example, since all the transport cylinders in the transport path through which the recording medium on which the image is transferred passes may be contaminated by ink, a cleaning unit having a similar configuration for cleaning these transport cylinders may be used. You may provide with respect to a conveyance cylinder. That is, generally, an impression cylinder cleaning unit having the above-described configuration may be provided for a rotating body through which a recording medium having an image transferred thereon passes.

  In the above embodiment, the cleaning roller and the guide roller are cleaned by operating the cleaning roller driving unit (not shown) and rotating the cleaning roller. However, the present invention is not limited thereto. Instead of rotating the cleaning roller, for example, the cleaning target surface may be cleaned by repeating the contact operation with various cleaning targets using the cleaning roller rotating operation by the operation of the cleaning roller rotating unit. . At that time, since the cleaning roller does not need to rotate, a cleaning member wrapped with a non-rotating cloth may be used.
