JP-A-2002-193509 - However, in the recording apparatus described above of the related art including the adhesive belt that supports and transports the recording medium on the support surface, a separation load may be increased when separating the recording medium from the support surface. If the separation load is increased, there is a concern that the recording medium is wound on the adhesive belt without being separated in a position of a predetermined range.
- Moreover, there is no description nor suggestion about a decrease in the separation load when separating the recording medium from the support surface in
JP-A-2007-196625 JP-A-2002-193509 - An advantage of some aspects of the invention is to decrease a separation load when separating a recording medium from a support surface in a recording apparatus including an adhesive belt that supports and transports the recording medium on the support surface.
- According to an aspect of the invention, a recording apparatus includes: an adhesive belt that supports and transports a recording medium on a support surface; a sensor that detects whether or not an angle formed between the support surface and a part of the recording medium which is separated from the support surface is in a range of 80° or more and 100° or less at a separation position of the recording medium from the support surface; a winding section on which the recording medium is wound; and a control section that controls the winding section to be driven when the sensor detects that the angle is in the range at the separation position.
- Here, "the adhesive belt" means a belt that is capable of holding the recording medium to separate on the surface supporting the recording medium. For example, the adhesive belt is a belt to which adhesive is applied, an electrostatic attraction belt, or the like.
- Moreover, a separation load is minimized when separating the recording medium in the separation position in which the angle is 90°. In this case, the control section controls the winding section to be driven when the sensor detects that the angle is in a range of 80° or more and 100° or less. That is, it is possible to separate the recording medium in the vicinity of the separation position in which the angle is 90° at which the separation load is minimized. Thus, it is possible to decrease the separation load of the recording medium.
- The control section may control the winding section to stop driving thereof when the sensor detects that the angle is in the range in the separation position in a state where the winding section is driven.
- In this case, the control section controls the winding section to stop the driving thereof when the sensor detects that the angle is in the range in the separation position in a state where the winding section is driven. That is, when the sensor detects that the angle is in the range in a state where the driving of the winding section is stopped, the winding section is driven, and when the sensor detects that the angle is in the range in a state where the winding section is driven, the driving of the winding section is stopped. Therefore, it is possible to maintain the separation position in the vicinity of a position in which the angle is 90°. Thus, it is possible to accurately decrease the separation load of the recording medium.
- The adhesive belt may be extended between a plurality of rotating bodies and the separation position may be positioned within a range in which a surface opposite to the support surface comes into contact with the rotating bodies.
- In this case, the separation position is positioned within the range in which the surface opposite to the support surface comes into contact with the rotating bodies. If the separation position is within the range in which the surface opposite to the support surface comes into contact with the rotating bodies, it is possible to control vibration of the adhesive belt when separating the recording medium from the support surface. Thus, it is possible to suppress deterioration of the quality of a recording image by the vibration of the adhesive belt when separating the recording medium from the support surface.
- According to another aspect of the invention, a recording method includes: supporting and transporting a recording medium on a support surface of an adhesive belt; detecting whether or not an angle formed between the support surface and a part of the recording medium separated from the support surface is in a range of 80° or more and 100° or less at a separation position of the recording medium from the support surface; and driving a winding section on which the recording medium is wound when detecting that the angle is in the range at the separation position in the detecting step.
- In this case, the winding section is driven when detecting that the angle is in the range of 80° or more and 100° or less. That is, it is possible to separate the recording medium in the vicinity of the separation position in which the angle is 90° at which the separation load is minimized.

-
Fig. 1 is a schematic side view illustrating arecording apparatus 1 according to one embodiment of the invention. - The
recording apparatus 1 of the embodiment includes anadhesive belt 2 that is extended between adriving roller 3 that rotates in a rotation direction C and a drivenroller 4 and supports a recording medium P on a support surface S1, and transports the recording medium P in a transportation direction A. In other words, theadhesive belt 2 is a transportation belt that is extended between a plurality of rotating bodies and supports, and transports the recording medium P. Therecording apparatus 1 of the embodiment includes two rollers of thedriving roller 3 and the drivenroller 4 as the plurality of rotating bodies, but may include three or more rollers and a plurality of rollers among them may be the driving roller. - Here, "the adhesive belt" means a belt that is capable of separably holding the recording medium on the surface on which the recording medium is supported. For example, the adhesive belt is a belt on which adhesive is applied, an electrostatic attraction belt, or the like. The
adhesive belt 2 of the embodiment is a belt on which the adhesive is applied. - Furthermore, a
recording head 6 is provided in a transportation path of the recording medium P by theadhesive belt 2. Therecording apparatus 1 forms a desired image by ejecting ink from an ink ejecting surface F of therecording head 6 to the recording medium while reciprocating therecording head 6 in a direction B intersecting the transportation direction A through a carriage 5. - Furthermore, the
recording apparatus 1 of the embodiment which includes therecording head 6 performs recording while reciprocating, but may also be a recording apparatus which includes a so-called line head in which a plurality of nozzles ejecting the ink are provided in the direction intersecting the transportation direction A. - Here, "line head" is a recording head that is used in the recording apparatus forming an image, in which a region of the nozzles formed in the direction intersecting the transportation direction A of the recording medium P is provided so as to be capable of covering an entire recording medium P in the intersecting direction and one of the recording heads and recording medium is fixed, and the other one is moved. Moreover, the region of the nozzles of the line head in the intersecting direction may be not capable of covering the entirety of the recording medium P in the intersecting direction, which corresponds to the recording apparatus.
- Furthermore, the direction B corresponds to a width direction of the recording medium P.
- In the
recording apparatus 1 of the embodiment, as described below, the recording medium P is separated from theadhesive belt 2 in a separation position having an angle of a predetermined range and is wound on awinding section 8 through a drivenroller 7 that is fixed at a predetermined position. Moreover, thewinding section 8 rotates the recording medium P in the rotation direction C when winding the recording medium P. - A
sensor 10 is provided between the separation position in which the recording medium P is separated from theadhesive belt 2 and a position in which the drivenroller 7 is provided in the transportation path of the recording medium P. - Here, the
sensor 10 is an optical sensor that irradiates light from a direction intersecting a surface of the recording medium P and detects that the recording medium P is separated from theadhesive belt 2 by a reflected light from the surface of the recording medium P (seeFigs. 3 to 5 ). - Thus, for example, the light is irradiated from a direction intersecting the surface of the recording medium P and the reflected light is detected by being blocked by the recording medium P by using the optical sensor which has the configuration that the reflection section is provided on a side facing an irradiation section and the reflected light from the reflection section is received. Therefore, detection accuracy is improved over the method of the related art to detect that the recording medium P is separated from the
adhesive belt 2. In such a method of the related art, since a length (thickness) in the direction intersecting the surface of the recording medium P is short, a detection timing in the optical sensor and a timing when the reflected light is blocked by the recording medium P deviates so that a detection error may occur. - Next, an electrical configuration in the
recording apparatus 1 of the embodiment will be described. -
Fig. 2 is a block view of therecording apparatus 1 according to the embodiment of the invention. - A control section 11 is provided with a
CPU 12 that performs control of anentire recording apparatus 1. TheCPU 12 is connected to aROM 14 in which various control programs, maintenance sequences, or the like which are executed by theCPU 12 is stored, and aRAM 15 which is capable of temporarily storing data through asystem bus 13. - Furthermore, the
CPU 12 is connected to ahead driving section 16 driving therecording head 6 through thesystem bus 13. - Furthermore, the
CPU 12 is connected to amotor driving section 17 that drives acarriage motor 18 that moves the carriage 5, atransportation motor 19 that is a drive source of the drivingroller 3 as a moving mechanism of theadhesive belt 2 on which the recording medium P is supported and transported, and a windingmotor 20 that is a drive source of the windingsection 8 through thesystem bus 13. - Furthermore, the
CPU 12 is connected to an input-output section 21 through thesystem bus 13 and the input-output section 21 is connected to thesensor 10, and aPC 22 that is an external device from which recording data and the like are input into therecording apparatus 1. - Next, the configuration will be described in detail with reference to an enlarged view of a main portion of the
recording apparatus 1 of the embodiment. -
Figs. 3 to 5 are enlarged views of a main portion of therecording apparatus 1 of the embodiment. - As described below, the
recording apparatus 1 of the embodiment is configured such that when thesensor 10 detects that aseparation position 23 of the recording medium P from the support surface S1 is at apredetermined position 9 in which the recording medium P separated from the support surface S1 forms an angle of 80° or more and 100° or less with respect to the support surface S1, the windingsection 8 is driven. - Thus,
Figs. 3 to 5 are described below in detail. -
Fig. 3 illustrates a state where thesensor 10 does not detect the recording medium P and the driving of the windingsection 8 is stopped. - Furthermore,
Fig. 4 illustrates a state immediately after thesensor 10 detects the recording medium P in the state where the driving of the windingsection 8 is stopped. - Furthermore,
Fig. 5 illustrates a state where thesensor 10 detects the recording medium P and the windingsection 8 is driven. - In the
recording apparatus 1 of the embodiment, the drivingroller 3 is rotated and theadhesive belt 2 is moved with the recording by therecording head 6, and theseparation position 23 of the recording medium P with respect to the support surface S1 is also moved with the movement of theadhesive belt 2. - The
recording apparatus 1 of the embodiment is configured such that when theseparation position 23 reaches thepredetermined position 9, the recording medium P enters a detection range of a length L1 with respect to the sensor 10 (seeFig. 4 ). - Here, the
recording apparatus 1 of the embodiment is configured such that an angle Θ of the recording medium P separated from the support surface S1 with respect to the support surface S1 is 80° or more and 100° or less when theseparation position 23 reaches thepredetermined position 9. - Moreover, as illustrated in
Fig. 3 , the angle Θ of the recording medium P separated from the support surface S1 with respect to the support surface S1 when theseparation position 23 reaches thepredetermined position 9 is an angle that is formed by the recording medium P and a plane S3 contacting to the support surface S1 in theseparation position 23 viewed in the width direction of the recording medium. That is, the angle Θ represents an angle that is formed by the support surface S1 and the recording medium P separated from the support surface S1 when theseparation position 23 reaches thepredetermined position 9. - In the invention, the sensor may detect whether or not the angle is in the range of 80° or more and 100° or less. Among the sensors, the
sensor 10 of the embodiment is a sensor that detects when theseparation position 23 reaches thepredetermined position 9 in which the angle is in the range of 80° or more and 100° or less. That is, "detecting whether or not the angle is in the range of 80° or more and 100° or less" means that "detecting whether or not the separation position is at the predetermined position in which the angle is in the range of 80° or more and 100° or less" is included. - However, the invention is not limited to the configuration and the sensor may be configured so that even if the angle formed between the support surface S1 and the recording medium P separated from the support surface S1 is not in the range of 80° or more and 100° or less in the
separation position 23 of the recording medium P from the support surface S1 it is detected by a method other than the embodiment. - Then, when changing from the state of
Fig. 3 to the state ofFig. 4 , the windingsection 8 is driven by the control section 11. - Moreover, fabric is used as the recording medium P in the embodiment, but when the driving of the winding
section 8 is started, the recording medium P such as fabric is extended by tension. Then, the recording medium P is separated from theadhesive belt 2 by a state where the tension is applied to the recording medium P. On the other hand, even when the windingsection 8 is driven, since the tension is not applied to the recording medium P immediately, the recording medium P is not separated from theadhesive belt 2 immediately. That is, a time lag occurs from driving of the windingsection 8 to the separation of the recording medium P from theadhesive belt 2. -
Fig. 5 illustrates a state where the windingsection 8 is driven after occurrence of the time lag. - That is, in other words, the
recording apparatus 1 of the embodiment includes theadhesive belt 2 that supports and transports the recording medium P on the support surface S1, thesensor 10 that detects whether or not the angle formed between the support surface S1 and the recording medium P separated from the support surface S1 is in the range of 80° or more and 100° or less in theseparation position 23 of the recording medium P from the support surface S1, the windingsection 8 that winds the recording medium P, and the control section 11 that controls the windingsection 8 to be driven when thesensor 10 detects that the angle with respect to theseparation position 23 is in the range. - When the recording medium P is separated from the
separation position 23 at which the angle forms 90°, a separation load is at a minimum and therecording apparatus 1 of the embodiment can separate the recording medium P in the vicinity of the separation position where the angle in which the separation load is at aminimum forms 90°. Thus, the separation load of the recording medium P is decreased. - Furthermore, in the
recording apparatus 1 of the embodiment, when the windingsection 8 is driven in the state ofFig. 5 , after a while, a positional relationship between theseparation position 23 and thepredetermined position 9 reaches the state ofFig. 4 . Then, when becoming the state ofFig. 4 , the recording medium P is out of the detection range of the length L1 with respect to thesensor 10 and the driving of the windingsection 8 is stopped by the control of the control section 11. - Then, in the
recording apparatus 1 of the embodiment, the positional relationship between theseparation position 23 and thepredetermined position 9 becomes the state indicated inFig. 3 immediately after the driving of the windingsection 8 is stopped. - That is, in other words, in the
recording apparatus 1 of the embodiment, the control section 11 controls the windingsection 8 such that when thesensor 10 detects that the angle is in the range of 80° or more and 100° or less in theseparation position 23 in a state where the windingsection 8 is driven, the driving of the windingsection 8 is stopped. - Specifically, the control section 11 controls the winding
section 8 such that when thesensor 10 detects that theseparation position 23 is at thepredetermined position 9 in a state where the windingsection 8 is driven, the driving of the windingsection 8 is stopped. - That is, in the
recording apparatus 1 of the embodiment, when thesensor 10 detects that theseparation position 23 is at thepredetermined position 9 in a state where the driving of the windingsection 8 is stopped, the windingsection 8 is driven. When thesensor 10 detects that theseparation position 23 is at thepredetermined position 9 in a state where the windingsection 8 is driven, the driving of the windingsection 8 is stopped. - Therefore, it is possible to maintain the
separation position 23 in the vicinity of thepredetermined position 9, that is, in the vicinity of the separation position in which the angle forms 90°. Thus, it is possible to decrease the separation load of the recording medium P with a high accuracy. Moreover, thesensor 10 may be configured to detect that the angle is in the range of 80° or more and 100° or less by another method other than the configuration for detecting that theseparation position 23 is at thepredetermined position 9. - Furthermore, the
separation position 23 in therecording apparatus 1 of the embodiment is positioned within a range in which a surface S2 opposite to the support surface S1 comes into contact with the drivingroller 3 on which theadhesive belt 2 is extended. Specifically, inFigs. 3 to 5 , theseparation position 23 is positioned on the outside than a line E in the drivingroller 3 in the vertical direction through arotation center 24 of the drivingroller 3. - That is, in other words, in the
recording apparatus 1 of the embodiment, theadhesive belt 2 is extended on the drivingroller 3 and the drivenroller 4 that is the plurality of rotating bodies, and theseparation position 23 is positioned within the range in which the surface S2 opposite to the support surface S1 comes into contact with the drivingroller 3. - If the
separation position 23 is within the range in which the surface S2 opposite to the support surface S1 comes into contact with the drivingroller 3, it is possible to suppress vibration of theadhesive belt 2 when the recording medium P is separated from the support surface S1. - Thus, the
recording apparatus 1 of the embodiment is configured such that it is possible to suppress the quality of the recording image from decreasing due to the vibration of theadhesive belt 2 when the recording medium P is separated from the support surface S1. - When summarizing the description of the
recording apparatus 1 of the embodiment, in therecording apparatus 1 of the embodiment, theseparation position 23 of the recording medium P from theadhesive belt 2 in which the recording medium P is supported and transported on the support surface S1 is maintained in the vicinity of the position in which the recording medium P forms the angle of 90° with respect to the support surface S1. - Thus, it is possible to decrease the separation load of the recording medium.
- Next, an embodiment of a recording method using the
recording apparatus 1 of the above embodiment will be described. -
Fig. 6 is a flow chart of the recording method of the embodiment. - First, in Step S10, a user sets the recording medium P in the
recording apparatus 1. Specifically, the rolled recording medium P is supported (adhered) on the support surface S1 of theadhesive belt 2 and a leading portion of the recording medium P is wound on the windingsection 8 through the drivenroller 7. - Next, in Step S20, the recording is performed by the
recording head 6 based on the recording data input from thePC 22 and the recording medium P is supported and transported on the support surface S1 of the adhesive belt 2 (transporting process). - Next, in Step S30, the
sensor 10 detects whether or not the angle between the support surface S1 and the recording medium P separated from the support surface S1 is in the range of 80° or more and 100° or less in theseparation position 23 of the recording medium P from the support surface S1 (detecting process). - In Step S30, when detecting that the angle is in the range, the process proceeds to Step S40 and when not detecting that the angle is in the range, the process proceeds to Step S50.
- In Step S40, the winding
section 8 on which the recording medium P is wound is driven by the control of the control section 11 (driving process of the winding section). - Thereafter, the process proceeds to Step S60.

- In Step S60, whether or not the recording is completed is determined in the control section 11 based on the recording data input from the
PC 22. - In Step S60, when the recording is not determined to be completed, the process proceeds to Step S70 and when the recording is determined to be completed, the recording method of the embodiment is completed.
- In Step S70, whether or not the angle is in the range of 80° or more and 100° or less in the
separation position 23 of the recording medium P from the support surface S1 is detected by thesensor 10. - In Step S70, when detecting that the angle is in the range, the process proceeds to Step S80 and when detecting that the angle is not in the range, the process returns to Step S60.
- In Step S80, the driving of the winding
section 8 on which the recording medium P is wound is stopped by the control of the control section 11. - Thereafter, the process proceeds to Step S90.
- In Step S90, whether or not the recording is completed is determined by the control section 11 based on the recording data input from the
PC 22. - In Step S90, when the recording is not determined to be completed, the process returns to Step S30 and when the recording is determined to be completed, the recording method of the embodiment is completed.
- According to the recording method of the above embodiment, it is possible to separate the recording medium P in the vicinity of the separation position where the angle at which the separation load is at a minimum and forms 90°. Thus, it is possible to decrease the separation load of the recording medium P.
