- the recording apparatus 1 of the embodiment includes the cleaning brush 13 as a cleaning section of the adhesive belt 10.
- the cleaning brush 13 changes a cleaning region of the adhesive belt 10 in the intersecting direction B.
- the controller 34 of the embodiment is capable of setting the cleaning region based on the detection result of the scan sensor 20.

TheCPU 35 is connected to aROM 26 in which various control programs, and the like executed by theCPU 35 are stored, and aRAM 27 which is capable of temporarily storing data, through asystem bus 36. - Also, the
CPU 35 is connected to thehead driving section 28 for driving theline head 19, through thesystem bus 36. - In addition, the

controller 23 controls movement of thescan sensor 20 in the intersecting direction B, and is capable of controlling discharging of the ink in theline head 19 based on a detection result of thescan sensor 20. - That is, the
recording apparatus 1 of the embodiment includes theadhesive belt 10 which is the transport section of the recording medium P, and theline head 19 of which the nozzles N for discharging the ink in the intersecting direction B intersecting the transport direction A of the recording medium P are arranged.

In addition, since thecontroller 34 controls the movement in the intersecting direction B of thescan sensor 20 and controls discharging of the ink based on the detection result of thescan sensor 20, therecording apparatus 1 of the embodiment is capable of accurately arranging the discharging position of the ink using theline head 19 with respect to the position of the recording medium P (position of medium). - Next, an example of a control method of the
recording apparatus 1 of the embodiment will be described. -
Figs. 4A and 4B illustrate schematic view for describing the example of the control method of therecording apparatus 1 of the embodiment. InFigs. 4A and 4B, Fig. 4A illustrates an arrangement of thehead units 7 in theline head 19 and an example of a positional relationship between theline head 19 and the recording medium P in a state of being transported. In addition,Fig. 4B is an enlarged view of an IVB region of a part ofFig. 4A , and illustrates a positional relationship between the nozzles N of thehead units 7 and theend portion 25 of the recording medium P in a state of being transported. -
Figs. 5A and 5B illustrate schematic views for describing another example of the control method in therecording apparatus 1 of the embodiment. InFigs. 5A and 5B, Fig. 5A illustrates an arrangement of thehead units 7 in theline head 19, and an example of a positional relationship between theline head 19 and the recording medium P in a state of being transported. In addition,Fig. 5B illustrates an enlarged view of a VB region of a part ofFig. 5A , and illustrates a positional relationship between thehead units 7 and theend portion 25 of the recording medium P in a state of being transported. - The
controller 34 of the embodiment is capable of selecting the nozzles N1 to be used in the nozzles N based on the detection result of the scan sensor 20 (refer toFigs. 4A and 4B ). Specifically, based on the detection result of thescan sensor 20, thecontroller 34 determines whether or not theend portion 25 is positioned at which position of theline head 19 in the intersecting direction B. Also, as illustrated inFig. 4B , thecontroller 34 sets the nozzles N at the position facing the recording medium P of an arrow R1 side further than theend portion 25 to the nozzles N1 to be used, and sets the nozzles N at the position not facing the recording medium P of an arrow R2 side further than theend portion 25 to the nozzles N2 not to be used. Accordingly, by selecting such a control method, that is, when the nozzles N1 to be used from the nozzles N are selected, therecording apparatus 1 of the embodiment is capable of easily accurately arranging the discharging position of the ink using theline head 19 with respect to the position of the medium. - In addition, the
recording apparatus 1 of the embodiment is configured to have thehead units 7 in which the nozzles N are arranged in the intersecting direction B, which are arranged multiple in the intersecting direction B; however, thecontroller 34 of the embodiment is capable of selecting the head units 7a which are used from thehead units 7, based on the detection result of the scan sensor 20 (refer toFigs. 5A and 5B ). Specifically, based on the detection result of thescan sensor 20, thecontroller 34 determines whether or not theend portion 25 is positioned at which position of theline head 19 in the intersecting direction B. Also, as illustrated inFig. 5B , thecontroller 34 sets thehead units 7 of the arrow R1 side further than theend portion 25 and thehead units 7 disposed at a position including theend portion 25 to the head units 7a being using, and sets thehead units 7, which is not including theend portion 25, of the arrow R2 side further than theend portion 25 to the head units 7b not to be used. Accordingly, by selecting such a control method, that is, when the head units 7a to be used from thehead units 7 are selected, therecording apparatus 1 of the embodiment is capable of easily accurately arranging the discharging position of the ink using theline head 19 with respect to the position of the medium. - In addition, the
controller 34 of the embodiment is capable of outputting an error, in a case in which a length in the intersecting direction B of the recording medium P based on recording data (data of ink discharging) is different from the length L1 (refer toFig. 4A ) in the intersecting direction B of the recording medium P based on the detection result of thescan sensor 20. Therefore, in a case in which a width of the medium in the intersecting direction B of the recording medium P, which is input to thecontroller 34 set when a user selects the recording medium P to be used by using thePC 38, or the like, is different from the length L1, that is, in a case in which the recording medium P to be assumed is different from the recording medium P set in therecording apparatus 1, it is possible to urge the user to change an appropriate recording medium P. Therefore, therecording apparatus 1 of the embodiment is capable of suppressing recording on the recording medium P different from the recording medium P to be assumed. - In addition, in a case in which a discharging width in the intersecting direction B is calculated based on the recording data (ink discharging data) and the calculated discharging width is longer than the length L1 (refer to
Fig. 4A ) in the intersecting direction B of the recording medium P based on the detection result of thescan sensor 20, thecontroller 34 of the embodiment is capable of outputting an error to thePC 38 serving as an alarm section. Accordingly, in a case in which the discharging width is longer than the length L1, it is possible to urge the user to modify the recording data so as to reduce the discharging width, or to change into the recording medium P having a wide width. Accordingly, therecording apparatus 1 of the embodiment is capable of suppressing the fact that an image formed using the ink discharged from theline head 19 is not fit into the recording medium P. - In addition, when the detection result of the
scan sensor 20 is input while reciprocating thescan sensor 20 in the intersecting direction B at the time of recording operation (ink discharging operation), thecontroller 34 of the embodiment is capable of suppressing discharging of the ink based on the detection result. Accordingly, at the time of the recording operation, therecording apparatus 1 of the embodiment is capable of accurately efficiently arranging the discharging position of the ink using theline head 19 with respect to the position of the medium by suppressing discharging of the ink in real time based on the detection result of thescan sensor 20. - Also, when the
scan sensor 20 is reciprocated in the intersecting direction B before the recording operation, thecontroller 34 of the embodiment is capable of recognizing the position of theend portion 25, without detecting theend portion 25 in real time at the time of recording operation. - In addition, the
recording apparatus 1 of the embodiment has a configuration in which one end side (left side inFig. 2 ) in the intersecting direction B becomes a reference position for arranging the position in the intersecting direction B of the recording medium P. Also, thecontroller 34 is capable of setting a movement range in the intersecting direction B of thescan sensor 20, according to a length in the intersecting direction B of the recording medium P based on the recording data (ink discharging data). Accordingly, therecording apparatus 1 of the embodiment is capable of suppressing a movement in which thescan sensor 20 is moved to an unnecessary range (a range where the recording medium P absences) according to the length in the intersecting direction B of the recording medium P based on the recording data. - In addition, as described above, the
recording apparatus 1 of the embodiment includes the meanderingdetection sensor 16. Here, when the user moves the meandering detection sensor in manual and disposes it at a predetermined position, the meanderingdetection sensor 16 of the embodiment is capable of detecting whether or not the recording medium P is meandered and transported by detecting theend portion 25 at the predetermined position. - The
controller 34 is capable of setting a movement range in the intersecting direction B of thescan sensor 20, based on a position of the meanderingdetection sensor 16 which is disposed by the user. Specifically, thecontroller 34 is capable of setting a movement range in the intersecting direction B of thescan sensor 20, so as not to include a range of the outside in the intersecting direction B further than the position of the meanderingdetection sensor 16 where the recording medium P is not exist. Accordingly, therecording apparatus 1 of the embodiment is capable of suppressing the fact that thescan sensor 20 is moved from the position of the meanderingdetection sensor 16 to an unnecessary range. - Also, as illustrated in
Fig. 1 andFig. 2 , thescan sensor 20 of the embodiment is disposed at an upstream side further than theline head 19 in the transport direction A. Accordingly, therecording apparatus 1 of the embodiment is capable of detecting a position of the recording medium P before the ink is discharged from theline head 19. - In addition, as illustrated in
Fig. 1 andFig. 2 , theadhesive belt 10, which is the transport section of the embodiment, is a transporting belt which transports the recording medium P while being attached thereto. - In the transporting belt which transports the recording medium P while being attached thereto, once the recording medium P is attached thereto (supporting recording medium P), it is suppressed that the recording medium P is deviated from the transporting belt. After detecting a transporting deviation of the recording medium P from the original position where the medium is intended to be transported, the recording medium P is suppressed to be further deviated therefrom.
- Here, after detecting a transporting deviation of the recording medium P from the original position where the medium is intended to be transported, and if there is a concern that the recording medium P is deviated, for example, it is preferable that the
scan sensor 20 is provided at a plurality of positions, such as a upstream side and a downstream side further than theline head 19. - However, the
recording apparatus 1 of the embodiment includes the transporting belt which transports the recording medium P while being attached thereto, and thus the recording apparatus is capable of sufficiently accurately detecting the transporting deviation of the recording medium P from the original position where the medium is intended to be transported with only onescan sensor 20. - In addition, as described above, the
recording apparatus 1 of the embodiment includes the cleaningbrush 13 as a cleaning section of theadhesive belt 10. The cleaningbrush 13 changes a cleaning region of theadhesive belt 10 in the intersecting direction B. - Also, the
controller 34 of the embodiment is capable of setting the cleaning region based on the detection result of thescan sensor 20. Specifically, based on the detection result of thescan sensor 20, the controller determines a region (a region is to be concerned of being contaminated due to the ink), where the ink is discharged, on the supporting surface F of theadhesive belt 10, and is capable of setting cleaning regions (selecting the cleaning rollers to be in contact with theadhesive belt 10 among the cleaning rollers 13a, 13b, 13c, and 13d) based on the determined result. In more detail, thecontroller 34 allows the cleaning rollers, which are disposed at a position including a region in the inside further than theend portion 25 in the intersecting direction B, to be in contact with theadhesive belt 10, and allows the cleaning rollers, which are not disposed at a position including a region in the inside further than theend portion 25 in the intersecting direction B, not to be in contact with theadhesive belt 10. For example, in a case in which the transporting position of the recording medium P with respect to theadhesive belt 10 and the cleaningbrush 13 is the positional relationship illustrated inFig. 2 , all of the cleaning rollers 13a, 13b, 13c, and 13d are disposed at the position including the region in the inside further than theend portion 25 in the intersecting direction B, and thus all of them are in contact with theadhesive belt 10. Meanwhile, when the recording medium P having a width thereof narrower than the recording medium P is used, for example, when the cleaning rollers 13c and 13d correspond to cleaning rollers, which are disposed at a position including a region of an inside further than theend portion 25, in a case in which the cleaning rollers 13a and 13b correspond to cleaning rollers, which are not disposed at the position including a region of an inside further than theend portion 25, the cleaning rollers 13c and 13d are in contact with theadhesive belt 10, and the cleaning rollers 13a and 13b are not in contact with theadhesive belt 10. - Accordingly, the
recording apparatus 1 of the embodiment is capable of suppressing inefficiency of cleaning the unnecessary region (region not contaminated with ink) in theadhesive belt 10. - Also, the invention is not limited to the embodiment described above, and can be variously changed within a range of the invention disclosed in Claims, further, it is needless to say that resultants thereof are also included in the range of the invention.
- For example, after detecting the position of the end portion of the recording medium P while moving the
scan sensor 20 like the above described embodiment, thescan sensor 20 is stopped at the position of the end portion, and the recording medium P can be detected at the position where the sensor is stopped. - In such a case, in a case in which the recording medium P is deviated from a detecting region where the
scan sensor 20 is stopped, or a case in which the position of the end portion is deviated from the position of the initially detected end portion further than a preset value, the recording medium P is determined to be meandered, and thus a predetermined meandering control can be performed or an error can be detected. When performing such a control, the meandering control can be performed with high accuracy, and the meandering control can be simply performed even in a case where the meanderingdetection sensor 16 is not provided as described above embodiment. - Hitherto, the invention has been described based on specific examples. Here, the outline of the invention will be described once more.
