1 is a schematic side view of a recording apparatus 1 according to Embodiment 1 of the present invention, and FIG. 2 is a schematic plan view of the recording apparatus 1 according to Embodiment 1 of the present invention.

  The recording apparatus 1 of the present embodiment includes a set unit 2 that can send out a roll R1 of a recording medium P that is a long recording medium for recording. Further, a pressure roller 12 as a first pressure unit and a pressure roller as a second pressure unit capable of pressing the recording medium P to the adhesive belt 10 as a movable belt and affixing the same. 19 and a transport mechanism 3 that transports the recording medium P in the transport direction A by the adhesive belt 10. In addition, a recording mechanism 4 is provided that records the recording head 7 by reciprocating scanning in a scanning direction B that intersects the conveyance direction A of the recording medium P. Further, a cleaning mechanism 15 for the adhesive belt 10 is provided. Furthermore, a winding mechanism 18 having a winding shaft 17 for winding the recording medium P and a cutter 16 for cutting the recording medium P being wound is provided.

The set unit 2 includes a rotating shaft 5 that also serves as a setting position of the roll R1 of the recording medium P for recording, and conveys the recording medium P from the roll R1 set on the rotating shaft 5 via the driven roller 6. The structure can be sent to the mechanism 3. When the recording medium P is sent out to the transport mechanism 3, the rotating shaft 5 rotates in the rotation direction C.
Here, the driven roller 6 serves as a scraping roller that suppresses generation of wrinkles on the recording medium P by rotating in the rotation direction C as the recording medium P is transported in the transport direction A. have.

  The transport mechanism 3 includes an adhesive belt 10 that continuously places and transports the recording medium P sent out from the setting unit 2, a transport roller 8 that moves the adhesive belt 10, and a driven roller 9. . The recording medium P is pressed and attached to the adhesive belt 10 by the pressure roller 12 and placed. When the recording medium P is transported, the transport roller 8 rotates in the rotation direction C.

Further, an optical sensor 36 as a detection unit capable of detecting a sticking failure of the recording medium P to the adhesive belt 10 is provided downstream of the pressure roller 12 and upstream of the recording head 7 in the transport direction A. I have. The optical sensor 36 includes a light emitting portion 36a and a light receiving portion 36b, and detects a convex portion generated due to the sticking failure. However, the detection unit is not limited to such a configuration.
The conveyance roller 8 which is a drive mechanism of the adhesive belt 10 drives the adhesive belt 10 to move the adhesive belt 10 in the direction opposite to the conveyance direction A when the optical sensor 36 detects the sticking failure. .

Further, a pressure roller 19 is provided on the downstream side in the transport direction A in the transport mechanism 3. The pressure roller 19 is a position where the recording medium P is separated from the adhesive belt 10 when the recording medium P is transported in the transport direction A, and also when the recording medium is moved in the direction opposite to the transport direction A. This is the placement position (attachment position) of the recording medium P to the adhesive belt 10. Since the pressure roller 19 is provided at this position, when the recording medium P is moved in the direction opposite to the conveyance direction A, that is, the part once separated from the adhesive belt 10 in the recording medium P is again used. When sticking to the adhesive belt 10, generation | occurrence | production of a new sticking defect can be suppressed.
For this reason, such a new sticking failure occurs, and the recording medium is damaged due to interference between the recording media or between the recording medium and the recording head, and the recording medium is wasted. This can be suppressed.

In the recording apparatus 1 of the present embodiment, when the optical sensor 36 detects a sticking failure, the transport roller 8 has a sticking failure portion on the upstream side of the driven roller 6 that is a scraping roller in the transport direction A. The adhesive belt 10 is driven so as to move. For this reason, it is possible to automatically eliminate the sticking failure by pasting the adhesive belt again on the adhesive belt while eliminating the sticking failure in the portion where the sticking failure has occurred.
However, the present invention is not limited to such a configuration. For example, when the optical sensor 36 detects a sticking failure, the transporting roller 8 moves to the upstream side of the pressure roller 12 in the transporting direction A. The adhesive belt 10 may be driven as described above. Even in such a configuration, the sticking failure portion is once separated from the adhesive belt 10 and pasted again, so that it is possible to automatically eliminate the sticking failure such as floating.

The recording mechanism 4 includes a recording head 7, a carriage (not shown) on which the recording head 7 is mounted, and a carriage motor 26 (see FIG. 4) that reciprocates the carriage in the scanning direction B. In FIG. 1, the scanning direction B is a direction perpendicular to the paper surface.
During recording, recording is performed by reciprocating the recording head 7. During the recording scanning (when the recording head is moving), the transport mechanism 3 stops the transport of the recording medium P. In other words, during recording, the reciprocating scanning of the recording head 7 and the conveyance of the recording medium P are alternately performed. That is, during recording, the conveyance mechanism 3 intermittently conveys the recording medium P corresponding to the reciprocating scanning of the recording head 7.
The recording apparatus 1 of the present embodiment includes the recording mechanism 4 having such a configuration, but is not limited to such a configuration, and may be configured to include a recording mechanism having a line head, for example.

  The winding mechanism 18 is a mechanism that winds the recording medium P on which recording has been performed and is transported from the transport mechanism 3 via the driven roller 11. A winding paper tube or the like is set on the winding shaft 17. By winding the recording medium P around this, the recording medium P can be wound as a roll R2.

  As shown in FIG. 2, in the recording apparatus 1 of the present embodiment, the pressure roller 12 has a length L2 in the scanning direction B at the contact portion with the recording medium P, and the scanning direction in the recording medium P. It is B length L1 or more. For this reason, the entire recording medium P can be pressurized in the scanning direction B. That is, since the pressure roller 12 can press the recording medium P with a wide contact surface, the occurrence of unevenness in the thickness of the recording medium P can be suppressed, and the unevenness in the recorded image can be suppressed. ing.

Also, the pressure roller 19 has a length L3 in the scanning direction B at the contact portion with the recording medium P equal to or longer than the length L1 in the scanning direction B on the recording medium P. For this reason, the detection unit 20 detects a sticking failure of the recording medium P to the adhesive belt 10 and drives the adhesive belt 10 so that the transport roller 8 moves the adhesive belt 10 in the direction opposite to the transport direction A. At this time, the entire recording medium P can be pressurized in the scanning direction B. That is, it is possible to suppress the occurrence of defective sticking of the recording medium P to the adhesive belt 10 when the portion once separated from the adhesive belt 10 is attached to the adhesive belt 10 again.
In order to prevent the pressure roller 19 from coming into contact with a recorded image on which ink fixing has not been completed and damaging the recorded image, the recording mechanism 4 and the pressure roller 19 in the transport direction A An ink fixing promotion mechanism may be provided between them. Examples of the ink fixing promotion mechanism include a heater and an air knife.

Next, the configuration of the scraping roller in the recording apparatus 1 of the present embodiment will be described.
FIG. 3 is a schematic diagram illustrating the driven roller 6 that is a scoring roller in the recording apparatus 1 of the present embodiment.
As shown in FIG. 3, the driven roller 6 of this embodiment is provided on the upstream side of the pressure roller 12 in the transport direction A of the recording apparatus 1 of this embodiment, and has an uneven shape on the surface. It has been. Further, when the recording medium P is rotated in the rotation direction C when the recording medium P is conveyed in the conveyance direction A, the recording medium P is changed from the inner side to the outer side in the width direction of the recording medium P (the same direction as the scanning direction B in this embodiment). Concavities and convexities are configured to move.
With such a configuration, the driven roller 6 of this embodiment extends the recording medium P in the width direction so that wrinkles or the like do not occur. Then, the recording apparatus 1 of this embodiment places the recording medium P in this state on the adhesive belt 10.

Next, the electrical configuration of the recording apparatus 1 of the present embodiment will be described.
FIG. 4 is a block diagram of the recording apparatus 1 of the present embodiment.
The control unit 20 is provided with a CPU 21 that controls the entire recording apparatus 1. The CPU 21 is connected via a system bus 22 to a ROM 23 that stores various control programs executed by the CPU 21 and a RAM 24 that can temporarily store data. The CPU 21 is connected to a head driving unit 25 for driving the recording head 7 via the system bus 22.

The CPU 21 is connected via a system bus 22 to a motor drive unit 32 for driving a carriage motor 26, a conveyance motor 27, a delivery motor 28 and a take-up motor 29.
Here, the carriage motor 26 is a motor for moving the carriage on which the recording head 7 is mounted. Further, the transport motor 27 is a motor for driving the transport roller 8. The sending motor 28 is a rotating mechanism of the rotating shaft 5 and drives the rotating shaft 5 in order to send the recording medium P to the transport mechanism 3. The winding motor 29 is a drive motor for rotating the winding shaft 17.

Further, the CPU 21 is connected via a system bus 22 to a cutter driving unit 33 that drives the cutter 16 to cut the recording medium P.
Further, the CPU 21 detects an optical sensor 36 as a detection unit capable of detecting a sticking failure of the recording medium P to the adhesive belt 10, a monitor 34 and a control panel 35 provided in the recording apparatus 1, and recording data. Are input from an external device such as a PC, etc., and an input / output unit 30 for transmitting and receiving data and signals.
Here, the monitor 34 also has a role as a notification unit that notifies that the optical sensor 36 has detected a sticking failure of the recording medium P to the adhesive belt 10, but is not limited to such a configuration. . For example, a mechanism capable of sounding a warning sound may be provided as the notification unit.

  The control unit 20 of this embodiment performs overall control of each drive unit of the recording apparatus 1. For this reason, when the optical sensor 36 detects the sticking failure, the conveyance roller 8 drives the adhesive belt 10 to move the adhesive belt 10 in the direction opposite to the conveyance direction A under the control of the control unit 20. Further, at this time, the control unit 20 also performs control for driving the adhesive belt 10 so that the sticking defective portion moves to the upstream side of the driven roller 6. In other words, the control unit 20 controls the transport roller 8 according to the detection result of the optical sensor 36. Further, the control unit 20 also performs control to display on the monitor 34 that the optical sensor 36 has detected that the recording medium P is stuck to the adhesive belt 10.

Further, in the recording apparatus 1 of the present embodiment, when the transport roller 8 has a part in the middle of recording along the scanning direction A when the optical sensor 36 detects the sticking failure, the part in the middle of recording is recorded. Is completed, the adhesive belt 10 is driven so as to move the adhesive belt 10 in the direction opposite to the conveyance direction A. For this reason, it is possible to prevent the recording position from becoming misaligned before and after the interruption by interrupting the recording in the state of having the part in the middle of recording and performing the recording subsequent to the part. it can.
The “part in the middle of recording” in this case occurs, for example, when recording is performed in a recording mode in which recording is completed by a plurality of recording scans on the same recording area. For example, when recording is performed in a recording mode in which recording is completed by two recording scans for the same recording area, and there is a portion where only one recording scan is performed, only the one recording scan is performed. The part that has not been performed corresponds to the part in the middle of recording. In this case, the recording apparatus 1 according to the present embodiment moves the adhesive belt 10 in the direction opposite to the conveyance direction A after performing the second recording scan on the portion where only the one recording scan is performed. The control of each driving unit regarding the operation of the recording apparatus 1 is performed by the control unit 20.

  Furthermore, in the recording apparatus 1 of the present embodiment, the control unit 20 performs control to display this on the monitor 34 every time the optical sensor 36 detects a sticking failure of the recording medium P to the adhesive belt 10. ing. However, it is not limited to such a control method. For example, when the optical sensor 36 detects a sticking failure, the process of returning the recording medium P to the upstream side of the driven roller 6 and the step of transporting in the transport direction A are performed several times. It is good also as a structure which alert | reports that the sticking defect was detected when it did not eliminate.

  In the recording apparatus 1 of the present embodiment, the pressure roller 19 pressurizes the recording medium P even when the recording medium P is transported in the transport direction A. However, it is not limited to this. For example, when the recording medium P is transported in the transport direction A, the recording medium P is moved to a position away from the recording medium so as not to be pressed by the pressure roller 19, and the optical sensor 36 has a sticking defect. When detected, the control unit 20 may control the recording medium P so that the recording medium P is transported in the direction opposite to the transport direction A by moving the pressure roller to a position to press the recording medium P. . By adopting such a configuration, it is possible to prevent the pressure roller 19 from coming into contact with the portion of the recording medium P where the image has been recorded, thereby damaging the recorded image on which the ink has not been fixed. can do.

[Example 2] (FIG. 5)

And a contact portion 38 with a cylindrical recording medium P extending in a direction along the rotation axis provided on both sides. For this reason, by recording an image on the inner side of the recording medium P in the width direction (scanning direction B), the contact between the pressure roller 37 and the image can be suppressed. That is, when the second pressurizing unit comes into contact with the portion of the recording medium P where the image is recorded, it is possible to suppress damage to the recorded image on which the ink has not been fixed.
That is, the recording apparatus 1 according to the present embodiment prevents the damage to the recorded image and re-adheres the portion once separated from the adhesive belt 10 as compared with the case where the pressure roller 37 is not provided. Generation | occurrence | production of the sticking defect at the time of sticking on the belt 10 can be suppressed.
