JP, 2012-046307, A

The inventor has found the following problems.
In the conventional recording apparatus, in order to feed the medium toward the winding unit, a method of operating the feeding unit and the winding unit synchronously and a method of operating the feeding unit with the winding unit stopped You could think so. However, in the former method, when the recording device can not recognize the roll radius of the medium wound up by the winding unit, the winding unit may wind up the medium more than necessary. In this case, the medium is not only wasted, but also the medium may be excessively pulled toward the winding unit and damaged. Also in the latter method, since the medium is not tensioned between the feeding unit and the winding unit, when the medium is stuck to a member on the feeding path due to static electricity, the medium is piled up at the sticking point. Curving in a shape (hereinafter, a portion in which the medium is curved in a mountain shape is referred to as a “mountain portion”), and the medium can not be sent first from the stuck portion. In this state, if the feed unit tries to further feed the medium, the generated mountain-like portion may grow, and the medium may be compressed to a narrow range, and the medium may be wrinkled.

  An object of the present invention is to provide a recording apparatus capable of appropriately feeding a medium toward a winding unit.

  The recording apparatus according to the present invention comprises a feeding unit for feeding the medium, a recording unit for printing on the medium, and a winding unit provided on the downstream side of the feeding of the medium than the feeding unit and for winding the medium. The feeding operation for feeding the medium while the winding unit stops the winding of the medium, and the winding operation for winding the medium when the feeding unit stops the feeding of the medium, It is characterized by repeating alternately.

  According to this configuration, since the feeding operation and the winding operation are alternately and repeatedly performed, the winding operation is performed before the mountain-like portion grows largely even when the mountain-like portion is generated in the medium by the feeding operation. The mountainous part is removed. Therefore, it is suppressed that the mountain-like part which generate | occur | produced grows and a medium becomes muffled. Therefore, the recording device can appropriately send the medium toward the winding unit.

  In this case, the feed unit preferably includes a roller pair for feeding the medium by rotation, and the roller pair preferably holds the medium when the winding operation is performed.

  According to this configuration, even when the winding unit tries to wind the medium more than necessary in the winding operation, the medium is held by the roller pair, so the winding unit winds the medium more than necessary. Is suppressed.

  In this case, the feed unit further includes a feed drive unit that rotates the roller pair, and the winding unit includes a winding side support unit that rotatably supports a winding core on which the medium is wound, and a winding core And a control unit for controlling the feed drive unit and the take-up drive unit, and the control unit stops the take-up drive unit so that the feed operation is performed. It is preferable to alternately repeat the feed process of operating the feed drive unit in the state and the winding process of operating the winding drive section in the state where the feed drive unit is stopped so that the winding operation is performed.

  According to this configuration, the control unit repeatedly performs the feeding process and the winding process alternately to stop the winding drive unit and operate the feeding drive unit, and the winding drive unit in which the feed drive unit is stopped. Is alternately repeated. Thus, the roller pair is rotated to feed the medium while the winding core stops rotating, and the winding core is rotated to wind the medium while the rotor pair is stopped from rotating. Is repeated.

  In this case, the control unit controls the winding drive unit so that the rotation direction of the winding core is switched between the winding direction in which the medium is wound and the reverse rotation direction opposite to the winding direction. The unit performs the feeding process and the winding process alternately repeatedly, and then performs the medium slack process and the medium slack process to operate the winding drive unit so that the winding core rotates in the reverse rotation direction. It is preferable that parameter setting processing for setting control parameters for controlling the winding drive unit is performed by operating the winding drive unit in a state where the medium is slack between the roller pair and the winding unit. .

  According to this configuration, the control unit repeatedly performs the feeding process and the winding process alternately, and then the control unit performs the medium slack process, whereby the medium is slackened between the roller pair and the winding unit. Is made. The control unit sets control parameters by performing parameter setting processing in this state. Then, as described above, the feeding operation and the winding operation are alternately repeated until the control parameter is set, whereby the medium is appropriately fed toward the winding unit. After the control parameter is set, the control unit controls the take-up drive unit using the control parameter to make the take-up unit operate in synchronization with the feed drive unit. It is possible to prevent the medium from being wound up more than necessary.

  In this case, the control unit further includes an operation unit that receives an operation for selecting one of the repetition mode and the non-repetition mode, and the control unit performs the sending process when the operation unit receives the selection operation of the repetition mode. And the winding process are alternately repeated, and when the operation unit receives the selection operation in the non-repetition mode, the feeding process is performed before the medium is slackened between the roller pair and the winding unit. It is preferable to perform one winding process and one sending process and not to perform a winding process.

  According to this configuration, when the non-repetitive mode is selected, instead of alternately performing the feeding operation and the winding operation, the feeding operation and the winding operation may be performed once or one. The winding operation is not performed. Therefore, when the non-repetitive mode is selected, the overall processing time is reduced as compared to when the repetitive mode is selected. Therefore, the user may select the non-repetitive mode when a medium that does not have the possibility of sticking to the member on the feed path due to static electricity or the like is used.

  In this case, the control unit further includes a platen provided opposite to the recording unit, and a suction unit for suctioning the medium onto the outer surface of the platen, and the control unit performs suction when the operation unit receives the repeat mode selection operation. It is preferable to stop the part.

  According to this configuration, when the repeat mode is selected, the feeding operation and the winding operation are alternately and repeatedly performed while the suction unit is stopped. This suppresses the sticking of the medium to the outer surface of the platen during the feeding operation, and suppresses the generation of a mountain portion in the medium at the platen.

FIG. 1 is a schematic configuration diagram of a recording apparatus according to an embodiment of the present invention. It is a control block diagram of a recording device shown in FIG. It is a flowchart which shows the initialization control which the recording device shown in FIG. 1 performs. (A) is a figure for demonstrating the sending operation | movement which the recording device shown in FIG. 1 performs, (b) is a figure for demonstrating the winding operation | movement which the recording device shown in FIG. 1 performs.

  Hereinafter, a recording apparatus 1 according to an embodiment of the present invention will be described with reference to the attached drawings. The recording apparatus 1 forms an image by applying a sublimation ink to a transfer sheet 100 by an inkjet method. The transfer paper 100 on which the image is formed is supplied to a thermal transfer device, and is heated in a state of being superimposed on a dyed object such as a fabric, whereby the image formed on the transfer paper 100 is transferred to the dyed object Ru.

  The schematic configuration of the recording apparatus 1 will be described with reference to FIG. The recording apparatus 1 includes a medium feeding mechanism 2, a platen 3, a recording unit 5, a drying unit 6, and a support frame 7 for supporting these. Although not shown in FIG. 1, the recording apparatus 1 includes a suction fan 4, an operation unit 8, and a control unit 9 (see FIG. 2).

  The medium feeding mechanism 2 feeds the transfer sheet 100, which is a continuous sheet, in a roll-to-roll method. The medium feeding mechanism 2 includes a feeding unit 11, a feeding unit 12, and a winding unit 13.

  In the delivery unit 11, a delivery side roll body 101 in which the transfer sheet 100 is wound in a roll shape is set. The delivery unit 11 includes a delivery side support 14 and a delivery motor 15 (see FIG. 2). The delivery side support portion 14 rotatably supports the delivery side roll body 101. The delivery motor 15 is a drive source for rotating the delivery roll body 101. When the delivery motor 15 is operated, the delivery side roll body 101 rotates in the delivery direction, and the transfer sheet 100 is delivered from the delivery side roll body 101.

The feeding unit 12 feeds the transfer sheet 100 fed from the feeding side roll body 101 toward the winding unit 13. The feed unit 12 includes a roller pair 16 and a feed motor 17 (see FIG. 2). The number of roller pairs 16 is not particularly limited, and a plurality of roller pairs 16 may be arranged along the feeding path of the transfer sheet 100. The roller pair 16 includes a drive roller 18 and a driven roller 19. The drive roller 18 is rotated by the transmission of power from the feed motor 17. The driven roller 19 is driven to rotate relative to the drive roller 18. The transfer sheet 100 is nipped between the driving roller 18 and the driven roller 19. The feed motor 17 serves as a drive source for rotating the drive roller 18. When the feed motor 17 is operated, the drive roller 18 is rotated, and the driven roller 19 pressed against the drive roller 18 is driven to rotate by the drive roller 18. As a result, the transfer sheet 100 nipped between the drive roller 18 and the driven roller 19 is fed toward the winding unit 13.
The driving roller 18 is provided with a feed side detection unit 21 (see FIG. 2) having a rotary encoder. Based on the pulse output from the feed-side detecting section 21, the rotation angle theta ₁ of the driving roller 18 is detected.

The winding unit 13 rolls up the transferred transfer sheet 100 in a roll shape. The winding unit 13 includes a winding side support 22 and a winding motor 23 (see FIG. 2). The take-up side support 22 rotatably supports a take-up paper tube 24. The front end of the transfer sheet 100 is attached to the paper tube 24. The paper tube 24 rotates as power is transmitted from the winding motor 23 through a gear train. The winding motor 23 is a drive source for rotating the paper tube 24. When the winding motor 23 rotates to one side, the paper tube 24 rotates in the winding direction, and the transfer paper 100 is taken up around the paper tube 24. A roll formed by winding the transfer sheet 100 around the paper tube 24 is referred to as a take-up roll 102. When the winding motor 23 rotates to the other side, the paper tube 24 rotates in the reverse rotation direction opposite to the winding direction, and the transfer paper 100 wound around the paper tube 24 is unwound.
The winding motor 23 is provided with a winding side detection unit 25 (see FIG. 2) having a rotary encoder. Based on the pulse output from the take-up detecting unit 25, the rotation angle theta ₀ of the winding motor 23 is detected.

  The platen 3 is provided on the downstream side of the transfer sheet 100 with respect to the roller pair 16. The platen 3 supports the transfer sheet 100 passing through the upper surface. A plurality of suction holes 26 are provided on the upper surface of the platen 3.

  The suction fan 4 is connected to the suction hole 26. When the suction fan 4 is operated, a negative pressure acts on the suction holes 26 and the transfer sheet 100 is adsorbed on the upper surface of the platen 3. Thus, the transfer sheet 100 is prevented from rising from the upper surface of the platen 3, and the transfer sheet 100 is prevented from interfering with the recording head 27 (described later) of the recording unit 5.

  The recording unit 5 is provided to face the upper surface of the platen 3. The recording unit 5 includes a carriage 28 and a recording head 27 mounted on the carriage 28. The recording head 27 discharges sublimation type ink to the transfer sheet 100 attracted to the upper surface of the platen 3. The carriage 28 on which the recording head 27 is mounted is configured to be reciprocally movable in a direction intersecting the feeding direction of the transfer sheet 100.

  The drying unit 6 is provided on the downstream side of the transfer sheet 100 with respect to the recording unit 5. The drying unit 6 includes an aluminum plate 31 which is a medium support unit, and a tube heater 32 provided on the back surface of the aluminum plate 31. The tube heater 32 generates heat, thereby promoting the drying of the transfer sheet 100 when the transfer sheet 100 to which the sublimation ink is applied passes the surface of the aluminum plate 31. The medium support portion may not be the aluminum plate 31 but may be a member of another material. Further, the member for heating the medium support portion is not limited to the tube heater 32, and any member that raises the temperature of the medium support portion may be used.

The support frame 7 has a bar member 33. The bar member 33 constitutes a feeding path of the transfer sheet 100 between the drying unit 6 and the winding unit 13.
In place of the bar member 33, it is conceivable to provide a tension bar for generating a tension on the transfer sheet 100. In that case, it is difficult to tightly wind the transfer sheet 100. On the other hand, as the take-up side roll body 102, when the take-up side roll body 102 is set in the thermal transfer device of the post process, in order to prevent meandering of the transfer sheet 100 delivered from the take-up side roll body 102. Preferably, the transfer sheet 100 is tightly wound. Therefore, as described later, the recording apparatus 1 winds up the transfer sheet 100 tightly with a constant tension by torque control on the winding motor 23.

  The recording apparatus 1 configured as described above operates to eject sublimation ink from the recording head 27 while the carriage 28 moves when the intermittent feeding of the transfer sheet 100 is stopped by the medium feeding mechanism 2; The operation of intermittently feeding the transfer sheet 100 is alternately repeated. Thereby, an image to be transferred to the transfer target is formed on the transfer sheet 100.

  The control system of the recording apparatus 1 will be described with reference to FIG. The operation unit 8 receives various operations from the user. The operation unit 8 includes a display for displaying an option, and an operation key for selecting and determining the displayed option. The operation unit 8 may have another configuration such as a touch panel. The operation unit 8 receives an operation for selecting the repeat mode and the non-repeat mode. The repeat mode, which will be described in detail later, is a mode in which the feed operation and the winding operation are alternately repeated in the initialization control, and the non-repeat mode is the feed operation and the winding operation in the initialization control. Is a mode in which the If the transfer sheet 100 is easily stuck to a member on the feed path due to static electricity or the like, such as thin paper, the repeat mode is selected. If not, the non-repeat mode is selected.

  The control unit 9 includes a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and the like (not shown). The CPU of the control unit 9 loads a program from the ROM and executes the program using the RAM to control each part of the recording apparatus 1. Further, a host device (for example, a personal computer) (not shown) is communicably connected to the control unit 9. The control unit 9 acquires image data representing a print image from a host device or the like. The control unit 9 controls the discharge operation of the recording head 27 based on the image data.

  The control unit 9 controls the winding motor 23 based on the set torque T to generate a constant tension on the transfer sheet 100. The set torque T is calculated corresponding to the change of the roll radius R of the take-up side roll body 102 as described later.

  The control unit 9 performs parameter setting processing (see step S12 in FIG. 3) for calculating the set torque T in initialization control performed at the start of operation. Although a series of flows of initialization control will be described later, parameter setting processing will be described here.

The control unit 9 causes the transfer sheet 100 to be slackened between the roller pair 16 and the winding unit 13 before the parameter setting process, as described later. When the parameter setting process is started, the control unit 9 rotates the winding motor 23 with the transfer sheet 100 slackened. Thereby, the control unit 9 acquires the offset torque T ₀ of the winding motor 23. The offset torque T ₀ is acquired based on the current value required to rotate the winding motor 23 under static load.
Since the winding portion 13 is disposed at a lower position than the roller pair 16, when the transfer sheet 100 is loosened between the roller pair 16 and the winding portion 13, the transfer sheet 100 is a member on the feeding path. If it does not stick to this, it will be in the state where slack occurred in the winding-up part 13 side.

Subsequently, the control unit 9 rotates the feed motor 17 and the winding motor 23 in a state in which the transfer sheet 100 between the roller pair 16 and the winding unit 13 is tensioned. The control unit 9 determines the setting feed amount L which is the feed amount of the transfer sheet 100 sent at this time, the rotation angle θ ₁ of the drive roller 18 detected by the feed side detection unit 21, and the drive roller known. It calculates from the relationship of following Formula based on the relationship with 18 roller radius r.
L = r · θ ₁
Then, the control unit 9 knows the roll radius R of the take-up side roll body 102 by the setting feed amount L and the rotation angle θ ₂ of the take-up motor 23 detected by the take-up side detection unit 25. On the basis of the reduction ratio N of the gear train between the winding motor 23 and the paper tube 24, it is calculated from the relationship of the following equation.
R = (L / θ ₂ ) · N
The reduction ratio N is a value given by N = θ ₂ / θ ₀ when the rotation angle of the paper tube 24 is θ ₀ .

  Subsequently, the control unit 9 sets a setting tension F. The control unit 9 stores, for example, a table in which the type of transfer sheet 100 and the value of tension are associated, and sets the set tension F by referring to the table.

Control unit 9, the offset torque T ₀ acquired in this manner, the roll radius R, based on the set tension F, the set torque T of the winding motor 23, is calculated from the following relationship.
T = (F · R−T ₀ ) / N

  The control unit 9 controls the winding motor 23 on the basis of the set torque T set according to the roll radius R of the winding side roll body 102 as described above. Thus, even when the control unit 9 causes the winding motor 23 to operate in synchronization with the feed motor 17 when recording is performed by the recording unit 5, for example, the winding unit 13 makes the transfer sheet 100 more than necessary. It is possible to suppress the winding or the insufficient winding amount.

However, as described above, when the control unit 9 obtains the offset torque T ₀ , it is necessary to rotate the winding motor 23 in a state in which the transfer sheet 100 between the roller pair 16 and the winding unit 13 is slack. There is. In order to make the transfer sheet 100 slack, after the feed unit 12 and the winding unit 13 are operated in synchronization, the transfer sheet 100 taken up by the winding unit 13 is unwound. A method and a method of operating the feeding unit 12 with the winding unit 13 stopped can be considered. However, in the former method, since the recording apparatus 1 can not recognize the roll radius R of the transfer sheet 100 taken up by the take-up unit 13 at the start of operation, the take-up unit 13 unnecessarily transfers the transfer sheet 100. There is a risk of winding up. In this case, not only the transfer sheet 100 is wasted, but also the transfer sheet 100 may be pulled excessively toward the winding portion 13 and damaged. Also in the latter method, since the transfer sheet 100 is not tensioned between the feeding unit 12 and the winding unit 13, the transfer sheet 100 is stuck to a member on the feeding path by static electricity or the suction force of the suction fan 4. If the sheet is attached, the transfer sheet 100 is curved in a mountain shape at the stuck portion (hereinafter, a portion in which the transfer sheet 100 is curved in a mountain shape is referred to as a “mountain portion 103”. See FIG. 4). The transfer sheet 100 can not be sent first from the point where the If the feeding unit 12 further tries to feed the transfer sheet 100 in that state, the generated mountain-like portion 103 grows, and the transfer sheet 100 may be pressed down in a narrow range, and the transfer sheet 100 may be wrinkled. In addition, there is a possibility that the grown mountain-like portion 103 may be in contact with a member constituting the recording apparatus 1 to be damaged or soiled.

  Therefore, as described below, the control unit 9 alternately repeats the feeding process and the winding process in the initialization control, so that the transfer sheet 100 between the roller pair 16 and the winding unit 13 is slackened. I am trying to make a state.

  A series of flows of initialization control performed by the control unit 9 will be described with reference to FIG. 4 based on the flowchart shown in FIG. When initialization control is started, in step S1, the control unit 9 determines whether the operation unit 8 has received a repeat mode selection operation. When the control unit 9 determines that the operation unit 8 has received the repeat mode selection operation (S1; Yes), the process proceeds to step S2. The controller 9 stops the suction fan 4 in step S2. In step S3, the controller 9 initializes a variable n to n = 1.

  In step S4, the control unit 9 performs a feed process of operating the feed motor 17 in a state in which the winding motor 23 is stopped. By this feeding process, with the winding unit 13 stopping winding of the transfer sheet 100, the feeding operation of the feeding unit 12 to transfer the transfer sheet 100 is performed. Here, the control unit 9 controls the feed motor 17 so that the transfer sheet 100 is fed by 1 / k (k is a predetermined integer of 2 or more) of the length D of the transfer sheet 100 necessary to make the slack. Do. At this time, if the transfer sheet 100 is stuck to a member on the feed path due to static electricity, a mountain-like portion 103 is formed on the transfer sheet 100 (see FIG. 4A).

  The value of k is not particularly limited as long as it is an integer of 2 or more. However, if the value of k is large, the amount of feed per one feeding operation decreases, and therefore, a mountain-like portion occurs The size of 103 can be further reduced, and interference of the mountain-like portion 103 with the recording head 27 etc. can be suppressed more effectively. On the other hand, when the value of k is small, the number of repetitions of the feeding operation and the winding operation is reduced, so that the time required to feed the transfer sheet 100 by the length D can be shortened.

In step S5, the controller 9 performs a winding process of operating the winding motor 23 in a state where the feed motor 17 is stopped. In a state in which the feeding unit 12 stops the feeding of the transfer sheet 100 by the winding process, that is, in a state in which the transfer sheet 100 is nipped by the roller pair 16, the winding section 13 winds the transfer sheet 100. Is done. Here, the control unit 9 controls the winding motor 23 so that the transfer sheet 100 is wound up by the feed amount of the transfer sheet 100 in step S3, that is, by the length D. The control unit 9, based on the initial torque T ₁ obtained in advance, and controls the winding motor 23. The initial torque T _1, if the roll radius R of the take-up side roll member 102 is within a predetermined range, regardless of the magnitude of the roll radius R of the take-up side roll member 102, the transfer sheet sandwiched between the roller pair 16 It is a torque that can take up the transfer sheet 100 without pulling out 100. By this winding operation, the mountain-like portion 103 is removed even when the mountain-like portion 103 is generated on the transfer sheet 100 in the preceding feeding operation (see FIG. 4B).

  In step S6, the control unit 9 determines whether n = k. If the controller 9 determines that n = k (S6; Yes), the process proceeds to step S11. If the controller 9 determines that n = k is not (S6; No), the process proceeds to step S7. move on. In step S7, the controller 9 adds 1 to n, and returns to step S4. Thus, the control unit 9 repeatedly performs steps S4 to S7 until n = k. Thus, the state in which the winding motor 23 is stopped and the feed motor 17 is operated, and the state in which the feed motor 17 is stopped and the winding motor 23 is operated are alternately repeated k times. Therefore, the feeding operation of feeding the transfer sheet 100 by (D / k) by the feeding unit 12 and the winding operation of winding the transfer sheet 100 by (D / k) by the winding unit 13 are alternately repeated k times It will be. As a result, the transfer paper sheet 100 of length D is taken up by the take-up unit 13.

  When control unit 9 determines in step S1 that operation unit 8 has received a selection operation in the non-repetition mode (S1; No), it proceeds to step S8. The controller 9 operates the suction fan 4 in step S8.

  In step S9, the controller 9 performs a feed process to operate the feed motor 17 in a state in which the winding motor 23 is stopped. By this feeding process, with the winding unit 13 stopping winding of the transfer sheet 100, the feeding operation of the feeding unit 12 to transfer the transfer sheet 100 is performed. Here, the control unit 9 controls the feed motor 17 so as to feed the transfer sheet 100 by the length D. When a medium that does not have the possibility of sticking to a member on the feed path due to static electricity or the like is used as the transfer sheet 100, the ridge portion 103 is less likely to occur on the transfer sheet 100. Therefore, the non-repetitive mode can be selected, and the transfer sheet 100 can be in a slack state between the roller pair 16 and the winding unit 13 without the transfer sheet 100 adhering to the member on the feed path. .

In step S10, the controller 9 performs a winding process of operating the winding motor 23 in a state where the feed motor 17 is stopped. By the winding process, in a state in which the feeding unit 12 stops the feeding of the transfer sheet 100, a winding operation is performed to wind the transfer sheet 100 by the winding unit 13. Here, the control unit 9 controls the winding motor 23 so that the transfer sheet 100 is wound up by the feed amount of the transfer sheet 100 at step S9, that is, by the length D. The control unit 9, similarly to step S5, based on the initial torque T ₁ obtained in advance, and controls the winding motor 23. After performing step S10, the control unit 9 proceeds to step S11.

  In step S11, the control unit 9 performs medium slack processing for operating the winding motor 23 so that the paper tube 24 rotates in the reverse rotation direction. By this medium slack processing, the transfer paper 100 is slackened between the roller pair 16 and the winding unit 13.

In step S12, the control unit 9 performs the parameter setting process described above. That is, the control unit 9 obtains the offset torque T ₀ of the winding motor 23 by operating the winding motor 23 in a state where the transfer sheet 100 is slackened between the roller pair 16 and the winding unit 13. The set torque T is set based on the offset torque T ₀ . Thereafter, the control unit 9 ends the series of processes in the initialization control.

  As described above, according to the recording apparatus 1 of the present embodiment, the feeding operation and the winding operation are alternately and repeatedly performed. The winding operation removes the ridges 103 before the ridges 103 grow large. In other words, by repeatedly performing the feeding operation and the winding operation, the transfer sheet 100 is sent to the winding unit 13 as if the size measurement operation is performed. Therefore, it is possible to prevent the transfer sheet 100 from being wrinkled by the growth of the generated mountain-like portion 103 and the transfer sheet 100 being pressed to a narrow range. Further, the possibility of the grown mountain-like portion 103 coming into contact with members constituting the recording apparatus 1 to be damaged or soiled can be reduced. Therefore, the recording apparatus 1 can appropriately feed the transfer sheet 100 toward the winding unit 13.

  According to the recording apparatus 1 of the present embodiment, the transfer sheet 100 is held by the roller pair 16 even when the winding unit 13 tries to take up the transfer sheet 100 more than necessary in the winding operation. It is suppressed that the winding unit 13 winds the transfer sheet 100 more than necessary.

  According to the recording apparatus 1 of the present embodiment, after the control unit 9 alternately and repeatedly performs the feeding process and the winding process, the control unit 9 performs the medium slack process, thereby the roller pair 16 and the winding unit 13 In this state, the transfer paper 100 is slackened. The control unit 9 sets the set torque T by performing the parameter setting process in this state. Then, as described above, the transfer operation and the winding operation are alternately repeated until the set torque T is set, whereby the transfer sheet 100 is appropriately fed toward the winding unit 13. After the setting torque T is set, the control unit 9 controls the winding motor 23 using the setting torque T so that the winding motor 23 is operated in synchronization with the feed motor 17 as well. It can be suppressed that the take-up unit 13 takes up the transfer sheet 100 more than necessary.

  According to the recording apparatus 1 of the present embodiment, when the non-repetitive mode is selected, instead of alternately performing the feeding operation and the winding operation, the feeding operation and the winding operation are performed once. Therefore, when the non-repetitive mode is selected, the overall processing time is reduced as compared to when the repetitive mode is selected. Therefore, the user selects the non-repetitive mode when the transfer sheet 100 which is not likely to stick to the member on the feed path due to static electricity or the like is used, for example, when the thickness of the transfer sheet 100 is relatively thick. Just do it.

  According to the recording apparatus 1 of the present embodiment, when the repeat mode is selected, the feeding operation and the winding operation are alternately repeated while the suction fan 4 is stopped. As a result, in the feeding operation, the transfer sheet 100 is prevented from sticking to the upper surface of the platen 3, and the generation of the mountain-like portion 103 on the transfer sheet 100 in the platen 3 is suppressed.

The suction fan 4 is an example of the "suction unit". The feed motor 17 is an example of a “feed drive unit”. The winding motor 23 is an example of a “winding drive unit”. The paper tube 24 is an example of a "winding core". The transfer sheet 100 is an example of the “medium”. The set torque T is an example of the “control parameter”.
It goes without saying that the present invention is not limited to the embodiment described above, and various configurations can be adopted without departing from the scope of the invention. For example, this embodiment can be modified into the following form.

  The recording apparatus 1 is not limited to one that forms an image to be transferred to a transfer target on the transfer sheet 100 as in the present embodiment. That is, the ink which the recording unit 5 discharges is not limited to the sublimation ink, and may be, for example, an aqueous ink, an oil ink, a solvent ink, or an ultraviolet curable ink. Furthermore, the recording method of the recording unit 5 is not limited to the inkjet method, and may be, for example, an electrophotographic method or a thermal method. The material of the medium is not particularly limited, and various media such as paper and film can be used. A thin sheet is often used as the transfer sheet 100. In that case, the present invention is particularly useful because the sheet is easily stuck to a member on the feed path by static electricity or the like.

  When the non-repetitive mode is selected, when the feeding operation is performed, the transfer sheet 100 is slackened between the roller pair 16 and the winding unit 13. Therefore, when the non-repetitive mode is selected, the control unit 9 may perform the parameter setting process as it is without performing the winding process and the medium slack process after performing the sending process.
