Description
- The present invention relates to a printing apparatus.
- In recent years, an ink jet type printing apparatus that performs printing of patterns, or the like, on a fabric by discharging an ink toward an outer surface of the fabric, has been used in textile printing on fabrics such as cotton, silk, wool, chemical fibers, and blended fabrics. In order to handle a stretchable fabric as a recording medium, a printing apparatus that is used in textile printing moves a recording medium by mounting the recording medium on an endless belt having a sticky property. In this kind of printing apparatus, an error in the movement amount of the endless belt occurs due to variations in the dimensions in the thickness direction of the endless belt. Therefore, for example, Japanese Patent No.
5332884 - In a printing apparatus that is provided with this kind of endless belt, in addition to variations in the thickness of the endless belt, a movement error amount of an endless belt differs depending on various printing conditions that are stipulated at a time of printing such as decentering of a belt driving roller that moves the endless belt, the type of recording medium, and the like. However, the printing apparatus that is disclosed in Japanese Patent No.
5332884 US-A1-2007/0236528 describes an ink-jet printer as defined in the preamble ofpresent claims - The invention can be realized in the following aspects or application examples.
- According to this application example, there is provided a printing apparatus including a driving roller, an endless belt that transports a recording medium using rotation of the driving roller, a roller correction table acquisition unit that acquires a roller correction table, which represents a relationship between a point of origin position of the driving roller and a movement error of the endless belt, a belt correction table acquisition unit that acquires a belt correction table, which represents a relationship between a point of origin position of the endless belt and a movement error of the endless belt, and a control section that controls driving of the driving roller by calculating a rotation amount of the driving roller on the basis of the roller correction table and the belt correction table.
- According to the application example, the printing apparatus includes the roller correction table acquisition unit that acquires a roller correction table, which represents a relationship between a point of origin position of the driving roller and a movement error of the endless belt. In other words, the printing apparatus includes a unit that determines a movement error of the endless belt caused by decentering of the driving roller. In addition, the printing apparatus includes a belt correction table acquisition unit that acquires a belt correction table, which represents a relationship between a point of origin position of the endless belt and a movement error of the endless belt. In other words, the printing apparatus includes a unit that determines a movement error of the endless belt caused by the thickness of the endless belt. Since the control section of the printing apparatus drives the driving roller by calculating a rotation amount of the driving roller on the basis of the roller correction table and the belt correction table, a movement error of the endless belt caused by decentering of the driving roller is corrected in addition to variations in the thickness of the endless belt. As a result of this, since the movement accuracy of the endless belt and the transport accuracy of a recording medium, which is mounted on the endless belt, are improved, it is possible to improve the printing quality of an image that is formed on the recording medium. Accordingly, it is possible to provide a printing apparatus in which the transport accuracy of a recording medium is improved and the printing quality of an image is improved.
- It is preferable that the printing apparatus according to the application example further includes roller correction tables and belt correction tables that correspond to printing conditions that are stipulated at a time of printing, and that the control section selects a roller correction table and a belt correction table that match the stipulated printing conditions.
- According to the application example, the printing apparatus includes roller correction tables and a belt correction tables that are acquired on the basis of various printing conditions that are stipulated at the time of printing. As a result of the control section of the printing apparatus driving the driving roller by calculating a rotation amount of the driving roller by selecting a roller correction table and a belt correction table that match the stipulated printing conditions, it is possible to perform correction that includes a movement error of the endless belt caused by the printing conditions.
- In the printing apparatus according to the application example, it is preferable that the printing conditions include printing quality.
- According to the application example, the printing apparatus includes the roller correction tables and a belt correction tables that are acquired on the basis of a printing quality that is stipulated at the time of printing. For example, a mode in which printing quality is prioritized, a mode in which printing velocity is prioritized, and the like, are examples of the printing quality. More specifically, the printing velocity differs depending on the printing quality. Since a movement error of the endless belt differs depending on the printing velocity, the printing apparatus of the present application example can perform correction that includes a movement error of the endless belt caused by differences in the printing velocity, which depends on the printing quality.
- In the printing apparatus according to the application example, it is preferable that the printing conditions include a medium type of the recording medium.
- According to the application example, the printing apparatus includes the printing roller correction tables and a belt correction tables that are acquired on the basis of a recording medium to be used in the printing. Since a movement error of the endless belt differs depending on the stretchability, and the like, of a recording medium to be used, the printing apparatus of the present application example can perform correction that includes a movement error of the endless belt caused by the recording medium to be used.
- In the printing apparatus according to the application example, it is preferable that the printing conditions include a condition relating to a tension at a time of transporting the recording medium.
- According to the application example, the printing apparatus includes roller correction tables and a belt correction tables that are acquired on the basis of a condition relating to a tension that is applied when transporting the recording medium, the condition being stipulated at the time of printing. For example, a "tension mode" that transports a recording medium by applying a predetermined amount of tension thereto, and a "slack mode" that reduces damage and transports a recording medium, and the like, are examples of transport methods. Since the amount of a movement error of the endless belt differs depending on a transport mode of a recording medium, the printing apparatus of the present application example can perform correction that includes a movement error of the endless belt caused by the transport method of the recording medium.
- It is preferable that the printing apparatus according to the application example further includes a tension measurement section that measures an amount of tension that is applied to the recording medium on at least one of an upstream side and a downstream side of the endless belt in a movement direction of the recording medium; and roller correction tables and belt correction tables that correspond to tension that can be measured by the tension measurement section, and that the control section selects a roller correction table and a belt correction table that match the tension that is measured by the tension measurement section.
- According to the application example, the printing apparatus includes the roller correction tables and a belt correction tables that are acquired on the basis of an amount of tension of the recording medium, which is measured by the tension measurement section. Since the control section selects a roller correction table and a belt correction table that match the tension that is measured by the tension measurement section, it is even possible to perform correction that includes a movement error of the endless belt caused by tension in a case in which there are fluctuations in the amount of tension of a recording medium during printing.

In the present embodiment, a configuration that forms an image on a band-like recording medium 95 using a roll method will be illustrated by way of example, but the embodiment is not limited to this configuration. For example, the embodiment may use a method such as a sheet technique. - As shown in
Fig. 1 , theprinting apparatus 100 includes a recordingmedium supply section 10, a recordingmedium transport section 20, a recordingmedium recovery section 30, aprinting section 40, acleaning unit 50, amedium adhesion section 60, a dryingsection 97, and the like. Further, theprinting apparatus 100 includes acontrol section 1 that controls each of these sections. Each section of theprinting apparatus 100 is attached to aframe section 92. - The recording
medium supply section 10 is a section that supplies arecording medium 95 on which an image is to be formed, to aprinting section 40 side. The recordingmedium supply section 10 includes asupply shaft section 11 and abearing section 12. Thesupply shaft section 11 is formed in a cylindrical shape or a columnar shape, and is provided so as to be rotatable in a circumferential direction. A band-like recording medium 95 is wound around thesupply shaft section 11 in roll shape. Thesupply shaft section 11 is attached to thebearing section 12 in an attachable and detachable manner. As a result of this, arecording medium 95 in a state of being wound around thesupply shaft section 11 in advance, can be attached to thesupply shaft section 11 and thebearing section 12. - The bearing
section 12 supports both ends in an axial direction of thesupply shaft section 11 in a rotatable manner. The recordingmedium supply section 10 includes a rotational driving section (not illustrated in the drawing) that drives thesupply shaft section 11 in a rotational manner. The rotational driving section rotates thesupply shaft section 11 in a direction in which arecording medium 95 is fed out. The operation of the rotational driving section is controlled by thecontrol section 1. - The recording
medium transport section 20 is a section that transports arecording medium 95 from the recordingmedium supply section 10 to the recordingmedium recovery section 30. The recordingmedium transport section 20 includes atransport roller 21, atension roller 22, atransport roller 23, abelt rotation roller 24, abelt driving roller 25 as a driving roller, anendless belt 26, atransport roller 27, atension roller 28 and atransport roller 29. - The
transport rollers tension roller 22 relay arecording medium 95 from the recordingmedium supply section 10 to theendless belt 26. Thetransport rollers frame section 92, and thetension roller 22 is provided between thetransport roller 21 and thetransport roller 23, and is a movable roller that is movable in a vertical direction (the Z axis direction). As a result of being able to move thetension roller 22 in the vertical direction, the amount of tension of arecording medium 95, which is supplied to theendless belt 26 from the recordingmedium supply section 10, can be varied. - The
endless belt 26 is formed in an endless shape in which both end portions of a band-like belt are connected to one another, and is hung on thebelt rotation roller 24 and thebelt driving roller 25. Theendless belt 26 is maintained in a state in which a predetermined tension is applied thereto so that a portion between thebelt rotation roller 24 and thebelt driving roller 25 is parallel to afloor surface 99. Asticky layer 26c, which causes arecording medium 95 to stick to theendless belt 26, is provided on an outer surface (a support surface) 26a of theendless belt 26. Theendless belt 26 supports (maintains) arecording medium 95, which is supplied from thetransport roller 23, and is adhered to thesticky layer 26c by themedium adhesion section 60, which will be described later. As a result of this, it is possible to handle a stretchable fabric, or the like as arecording medium 95. - The
belt rotation roller 24 and thebelt driving roller 25 support an innercircumferential surface 26b of theendless belt 26. Additionally, a configuration in which a support section that supports theendless belt 26, is provided between thebelt rotation roller 24 and thebelt driving roller 25, may also be used. - The
endless belt 26 moves a recording medium using rotation of thebelt driving roller 25. To explain in more detail, when thebelt driving roller 25 is driven, theendless belt 26 rotates in accordance with rotation of thebelt driving roller 25, and thebelt rotation roller 24 rotates due to rotation of theendless belt 26. As a result of rotation of theendless belt 26, arecording medium 95, which is supported on theendless belt 26, is transported in a predetermined transport direction, which is illustrated by an arrow, and an image is formed on therecording medium 95 by theprinting section 40, which will be described later. In the present embodiment, arecording medium 95 is supported on a side (a +Z axis side) on which theouter surface 26a of theendless belt 26 faces theprinting section 40, and therecording medium 95 is transported from abelt rotation roller 24 side to abelt driving roller 25 side along with theendless belt 26. In addition, on a side (a -Z axis side) on which theouter surface 26a of theendless belt 26 faces thecleaning unit 50, only theendless belt 26 moves from thebelt driving roller 25 side to thebelt rotation roller 24 side. - The
transport roller 27 causes arecording medium 95, on which an image is formed, to peel away from thesticky layer 26c of theendless belt 26. Thetransport rollers tension roller 28 relay arecording medium 95 from theendless belt 26 to the recordingmedium recovery section 30. Thetransport rollers frame section 92, and thetension roller 28 is provided between thetransport roller 27 and thetransport roller 29, and is a movable roller that is movable in the vertical direction (the Z axis direction). As a result of being able to move thetension roller 28 in the vertical direction, the amount of tension of arecording medium 95, which is peeled away from theendless belt 26 and recovered by the recordingmedium recovery section 30, can be varied. Additionally, a "tension mode", and a "slack mode", which will be described later, and which are conditions relating to the tension when transporting therecording medium 95, are realized due to the movability of thetension rollers - The recording
medium recovery section 30 recovers arecording medium 95 that is transported by the recordingmedium transport section 20. The recordingmedium recovery section 30 includes a wind-upshaft section 31 and abearing section 32. The wind-upshaft section 31 is formed in a cylindrical shape or a columnar shape, and is provided so as to be rotatable in a circumferential direction. A band-like recording medium 95 is wound up onto the wind-upshaft section 31 in roll shape. The wind-upshaft section 31 is attached to thebearing section 32 in an attachable and detachable manner. As a result of this, arecording medium 95 in a state of being wound-up onto the wind-upshaft section 31, is released along with the wind-upshaft section 31. - The bearing
section 32 supports both ends in an axial direction of the wind-upshaft section 31 in a rotatable manner. The recordingmedium recovery section 30 includes a rotational driving section (not illustrated in the drawing) that drives the wind-upshaft section 31 in a rotational manner. The rotational driving section rotates the wind-upshaft section 31 in a direction in which arecording medium 95 is wound up. The operation of the rotational driving section is controlled by thecontrol section 1. - Additionally, in the present embodiment, a drying
section 97 is disposed between thetransport roller 27 and thetension roller 28. The dryingsection 97 is a section that dries an image formed on arecording medium 95. For example, by including an IR heater in thedrying section 97, and driving the IR heater, it is possible to dry an image formed on arecording medium 95 in a short period of time. As a result of this, it is possible to wind up a band-like recording medium 95 on which an image is formed, onto the wind-upshaft section 31. - The
medium adhesion section 60 is a section that causes arecording medium 95 to adhere to theendless belt 26. Themedium adhesion section 60 is disposed further on an upstream side (a -X axis side) than theprinting section 40 in the transport direction of arecording medium 95. Themedium adhesion section 60 includes apressing roller 61, a pressingroller driving section 62 and aroller support section 63. Thepressing roller 61 is formed in a cylindrical shape or a columnar shape, and is provided rotatable so as to be rotatable in a circumferential direction. Thepressing roller 61 is disposed so that an axial direction thereof intersects the transport direction in a manner in which thepressing roller 61 rotates in a direction along the transport direction. Theroller support section 63 is provided on an innercircumferential surface 26b side of theendless belt 26, which faces thepressing roller 61 with theendless belt 26 interposed therebetween. - The pressing
roller driving section 62 moves thepressing roller 61 in the transport direction (a +X axis direction) and a direction (a -X axis direction) that is opposite to the transport direction while pressing thepressing roller 61 toward a lower side in the vertical direction (the -Z axis side). Arecording medium 95 that is transported from thetransport roller 23, and superimposed on theendless belt 26, is pressed against theendless belt 26 between thepressing roller 61 and theroller support section 63. As a result of this, it is possible to reliably cause arecording medium 95 to stick to thesticky layer 26c, which is provided on theouter surface 26a of theendless belt 26, and therefore, it is possible to prevent lifting of arecording medium 95 above theendless belt 26. - The
printing section 40 includes an ink jettype discharge head 42 that discharges an ink toward arecording medium 95 as liquid droplets, acarriage movement section 41 that moves acarriage 43, in which thedischarge head 42 is mounted, and the like. Theprinting section 40 is disposed above a disposition position of the endless belt 26 (on the +Z axis side). Adischarge surface 44, on which a plurality ofnozzle rows 45 are formed, is provided in thedischarge head 42. For example, fournozzle rows 45 are formed on thedischarge surface 44, and a different color of ink (for example, cyan: C, magenta: M, yellow: Y and black: K) is discharged from eachnozzle row 45. Thedischarge surface 44 faces arecording medium 95 that is transported by theendless belt 26. - The
carriage movement section 41 moves thedischarge head 42 in a direction that intersects the transport direction of a recording medium 95 (a width direction of a recording medium 95 (the Y axis direction)). Thecarriage 43 is supported by a guide rail (not illustrated in the drawing), which is disposed along the Y axis direction, and thecarriage 43 is configured so as to be able to reciprocate in a ±Y axis direction as a result of thecarriage movement section 41. For example, it is possible to use a configuration in which a ball screw and a ball nut are combined, a linear guide mechanism or the like, as thecarriage movement section 41. - Furthermore, a motor (not illustrated in the drawing) is provided in the
carriage movement section 41 as a motive power source for moving thecarriage 43 along the Y axis direction. When the motor is driven due to the control of thecontrol section 1, thedischarge head 42 reciprocates along the Y axis direction along with thecarriage 43. Additionally, in the present embodiment, a serial head type discharge head, which is installed in a movable carriage and discharges an ink while moving in the width direction of a recording medium 95 (the ±Y axis direction), is illustrated as thedischarge head 42 by way of example, but a line head type in which the discharge head is fixedly arranged extending in the width direction of a recording medium 95 (the Y axis direction) may be used instead. - The
printing apparatus 100 is provided with thecleaning unit 50 for cleaning theendless belt 26. Thecleaning unit 50 includes acleaning section 51, apressing section 52 and amovement section 53. Themovement section 53 can be fixed in a predetermined position by moving thecleaning unit 50 along thefloor surface 99 in an integral manner. Thecleaning unit 50 is disposed between thebelt rotation roller 24 and thebelt driving roller 25 in the X axis direction. - The
pressing section 52 is an elevation device that is configured by anair cylinder 56 and aball bush 57, and is capable of moving thecleaning section 51, which is provided above thepressing section 52, between a cleaning position and a retreat position. The cleaning position is a position in which acleaning roller 58 and ablade 55 abut against theendless belt 26. The retreat position is a position in which the cleaningroller 58 and theblade 55 are separated from theendless belt 26. In the cleaning position, thecleaning section 51 cleans theouter surface 26a (the support surface) of theendless belt 26, which is hanging in a state in which a predetermined amount of tension is applied between thebelt rotation roller 24 and thebelt driving roller 25, from below (a -Z axis direction). Additionally,Fig. 1 shows a case in which thecleaning section 51 is raised and disposed in the cleaning position. - The
cleaning section 51 includes a cleaningtub 54, the cleaningroller 58 and theblade 55. The cleaningtub 54 is a tub in which a cleaning solution that is used in the cleaning of ink and foreign matter that is attached to theouter surface 26a of theendless belt 26, is retained, and the cleaningroller 58 and theblade 55 are provided on an inner side of the cleaningtub 54. For example, it is possible to use water, a water-soluble solvent (an alcohol aqueous solution or the like), or the like, as the cleaning solution, and a surfactant, an antifoaming agent, and the like may be added thereto according to necessity. - A lower side (the -Z axis side) of the cleaning
roller 58 is immersed in the cleaning solution that is retained in the cleaningtub 54. When the cleaningroller 58 is rotated in the cleaning position, the cleaning solution is supplied to theouter surface 26a of theendless belt 26, and the cleaningroller 58 slides along theendless belt 26. As a result of this, ink and fibers or the like of a fabric of arecording medium 95, which are attached to theendless belt 26, are washed away using the cleaningroller 58. - For example, the
blade 55 is configured by a material having a flexible property such as a silicon rubber. Theblade 55 is provided further on a downstream side than the cleaningroller 58 in the transport direction of theendless belt 26. Cleaning solution that remains on theouter surface 26a of theendless belt 26, is removed as a result of theendless belt 26 sliding along theblade 55. -
Fig. 2 is a perspective view in which an endless belt is displayed in an enlarged manner.Fig. 3 is a cross-sectional view of a movement amount detection sensor. A movementamount detection sensor 70 and a belt point oforigin sensor 80 that determine a point of origin position and a movement amount of theendless belt 26 will be described with reference toFigs. 2 and 3 . - The belt point of
origin sensor 80 is a sensor that detects a point of origin of theendless belt 26. As shown inFig. 2 ,markers 81 are provided at both end portions in the width direction of the endless belt 26 (the Y axis direction) on theouter surface 26a, on which thesticky layer 26c is not formed, as points of origin of theendless belt 26. The belt point oforigin sensor 80 is provided above (in a +Z axis direction) themarker 81 in the vertical direction. When themarker 81 moves in accordance with movement of theendless belt 26 and passes under the belt point oforigin sensor 80, the belt point oforigin sensor 80 detects themarker 81 and outputs a detection signal thereof. - The movement
amount detection sensor 70 is a sensor that performs image process measurement of a practical (or an actual amount of movement in practice) movement amount of theendless belt 26. The movementamount detection sensor 70 captures images for determining a practical movement amount that theendless belt 26 moves in a practical sense through comparison of positions before movement and after movement of theendless belt 26. As shown inFigs. 2 and 3 , the movementamount detection sensor 70 is provided in a position that faces the printing section 40 (refer toFig. 1 ) with theendless belt 26 interposed therebetween, and captures images of the innercircumferential surface 26b of theendless belt 26. - Additionally, in the present embodiment, a configuration in which the movement
amount detection sensor 70 is provided on the innercircumferential surface 26b of theendless belt 26 is shown, but the movementamount detection sensor 70 is not limited to this configuration. The movementamount detection sensor 70 may be provided in any position in which it is possible to capture images of theouter surface 26a, on which thesticky layer 26c of theendless belt 26 is not formed, the outer surface of arecording medium 95 that is mounted on theendless belt 26, or the like. In addition, it is preferable that the movementamount detection sensor 70 is provided in the vicinity of theprinting section 40. In addition, in a case in which images of theouter surface 26a or the innercircumferential surface 26b of theendless belt 26 are captured, it is preferable that undulations are formed on the outer surface of a target of the image capture section. As a result of this, since a clear image is captured, the calculate accuracy of the movement amount of theendless belt 26 is improved. - As shown in
Fig. 3 , the movementamount detection sensor 70 is provided with a light-emittingsection 72, a condensinglens 73, and animage capturing element 74 on an inner side of acase 76. - The
case 76 configures the exterior of the movementamount detection sensor 70. Thecase 76 has a truncated cone shape, and a light-transmissive glass 71 is attached to a tip end portion (an upper end portion) thereof. The light-transmissive glass 71 faces a gap between the light-transmissive glass 71 and the innercircumferential surface 26b of theendless belt 26 in a vertical manner in a state in which a gap is interposed therebetween. - The light-emitting
section 72 is a section that radiates light toward theendless belt 26. The light-emittingsection 72 is provided on an inner wall surface of thecase 76 with an angled posture in which it is possible to emit light toward the light-transmissive glass 71. For example, it is possible to use a light emitting diode (LED) as the light-emittingsection 72. - The condensing
lens 73 is a lens that condenses reflected light that passes through the light-transmissive glass 71 for a second time and is incident to the inside of thecase 76 after light that is emitted from the light-emittingsection 72 and passes through the light-transmissive glass 71 is reflected by the innercircumferential surface 26b of theendless belt 26, and is provided in a cylindrical portion of thecase 76. - The
image capturing element 74 is an element that captures images of the innercircumferential surface 26b of theendless belt 26, which are condensed by the condensinglens 73, and includes animage capturing surface 74a in a position in which images are formed. Theimage capturing element 74 is provided on an inner bottom surface of thecase 76. Additionally, the condensinglens 73 is retained at a height at which an image of the innercircumferential surface 26b of theendless belt 26 on theimage capturing surface 74a of theimage capturing element 74 can obtained, by aretention member 75. - The movement
amount detection sensor 70 outputs image capturing data that is captured by theimage capturing element 74, to thecontrol section 1. Thecontrol section 1 compares image capturing data before and after movement of theendless belt 26, and outputs a practical movement amount that theendless belt 26 has moved in a practical sense. - Additionally, in the present embodiment, a method that uses the movement
amount detection sensor 70 as a measurement method of the practical movement amount of theendless belt 26, is illustrated by way of example, but the measurement method is not limited to this configuration. The measurement method of the practical movement amount of theendless belt 26 may be a method that uses a laser length measurement machine. For example, it is possible to measure the practical movement amount of theendless belt 26 by providing a reflective body, which reflects laser light emitted along a movement direction of theendless belt 26, on theendless belt 26, and measuring a distance between a laser length measurement machine and the reflective body, which moves along with theendless belt 26. In addition, it is possible to determine the practical movement amount of theendless belt 26 by repeating movement of theendless belt 26 and the discharge of liquid droplets onto arecording medium 95 such as photographic paper, and measuring a position of a measurement pattern (dots) that is formed on therecording medium 95. -
Fig. 4 is an electrical block diagram that shows an electrical configuration of the printing apparatus. Next, the electrical configuration of theprinting apparatus 100 will be described with reference toFig. 4 . - The
control section 1 is a control unit for performing control of theprinting apparatus 100. Thecontrol section 1 is configured to include acontrol circuit 4, an interface section (I/F) 2, a CPU (Central Processing Unit) 3, and astorage section 5. Theinterface section 2 is a section for performing the communication of data between anexternal apparatus 6, which handles images, such as a computer or a digital camera, and theprinting apparatus 100. TheCPU 3 is an arithmetic processing device for performing an input signal process fromvarious detector groups 7 and overall control of theprinting apparatus 100. Thedetector groups 7 include the movementamount detection sensor 70 for measuring the movement amount of theendless belt 26, the belt point oforigin sensor 80 that detects a belt point of origin of theendless belt 26, and a driving shaft point oforigin sensor 85 that detects a driving shaft point of origin of thebelt driving roller 25. - The
storage section 5 is a section for securing a region that stores a program of theCPU 3, a work region, or the like, and includes storage elements such as RAM (Random Access Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), or the like. In addition, roller correction tables and belt correction tables that correct a transport error of theendless belt 26, which will be described later, are stored in thestorage section 5. - The
CPU 3 controls thebelt driving roller 25 that moves theendless belt 26 in the transport direction, thecarriage movement section 41 that moves thecarriage 43, in which thedischarge head 42 is mounted, in a direction that intersects the transport direction, thedischarge head 42 that discharges ink toward arecording medium 95, and each device that is not illustrated in the drawings, on the basis of printing data and printing conditions that are received from theexternal apparatus 6 using thecontrol circuit 4. Additionally, for example, a printing quality, which is represented by "clear", "fast", or the like, a medium type to be used as arecording medium 95, a condition relating to the tension when transporting the recording medium, which is represented by a "tension mode", a "slack mode", or the like, are included as the printing conditions of the present embodiment. - Next, a transport error of the
endless belt 26 will be described. -
Fig. 5 is a view that shows an example of a transport error of the endless belt. The horizontal axis inFig. 5 represents an integrated movement amount when theendless belt 26 is rotated a single time by repeatedly moving theendless belt 26 by a predetermined movement amount from a predetermined position (for example, a point of origin position of the marker 81). That is, a maximum value of the horizontal axis inFig. 5 is equivalent to the length of theendless belt 26. The vertical axis inFig. 5 represents a difference (hereinafter, also referred to as a transport error) between practical movement amounts, which are calculated from image capturing data that is captured before and after movement of theendless belt 26, with respect to a predetermined (or intended) movement amount. - As shown in
Fig. 5 , in the transport error, an error that is expressed periodically in a period of an interval A, and an error, which is shown by an interval B, that is expressed specifically. The length of the interval A is substantially equivalent to the length of the outer periphery of thebelt driving roller 25, and it can be understood that the transport error of the interval A is caused by driving of thebelt driving roller 25. The reason for this is that the interval A is a so-called transport error that occurs as a result of decentering of thebelt driving roller 25, in which the center of the circumference (the outer periphery) of thebelt driving roller 25 and the center of the axis of rotation that drives thebelt driving roller 25 in a rotational manner, are shifted. The interval B is equivalent to a position of a connection section of theendless belt 26, and it can be understood that the transport error of the interval B is caused by the thickness of theendless belt 26. Additionally, a transport error caused by the thickness of theendless belt 26 in portions other than a connection section of theendless belt 26, are also included in practice. -
Fig. 6 is a view that describes a point of origin of a driving axis of a belt driving roller. Thebelt driving roller 25 is provided with the driving shaft point oforigin sensor 85. In addition, in the present description, the position of the driving shaft point oforigin sensor 85 is set as a reference position of thebelt driving roller 25. For example, it is possible to use a rotary encoder, which is provided with a marker as a driving shaft point of origin, or the like, as the driving shaft point oforigin sensor 85. The position of the driving shaft point of origin moves as a result of rotational driving of thebelt driving roller 25. Additionally, in the following description, the position of the driving shaft point of origin represents an angle θ that is formed by a line that connects the center of thebelt driving roller 25 and the reference position, and a line that connects the center of thebelt driving roller 25 and the driving shaft point of origin. In this way, the point oforigin sensor 85 measures how much the driving roller has rotated. Additionally, the driving shaft point of origin of thebelt driving roller 25 may be determined using an absolute-type rotary encoder that outputs an absolute position of the driving shaft point of origin that depends on a rotational angle. -
Fig. 7 is a view that shows an example of a roller correction table. The roller correction table represents a relationship between a point of origin position of a driving roller and a movement error of the endless belt. In the present embodiment, a plurality of roller correction tables, which correspond to a plurality of printing conditions, are stored in thestorage section 5. - Positions of the driving shaft point of origin of the
belt driving roller 25 are shown using the angles θ in the parameters in the rows of the roller correction table that is shown inFig. 7 , and reference movement amounts Kn are shown as predetermined movement amounts of theendless belt 26 in the parameters of the rows. Further, correction values α of the movement amounts are shown in intersecting positions of the respective parameters (the angles θ and the reference movement amounts Kn). - A roller correction table acquisition unit, which acquires roller correction tables, calculates correction values α of movement amounts from the reference movement amounts Kn, by which the
control section 1 feeds out theendless belt 26 by driving (rotating) thebelt driving roller 25, and practical movement amounts of theendless belt 26, which are determined using the movementamount detection sensor 70. Correction values α of at least a single circuit (an amount that is equivalent to 360°) of thebelt driving roller 25 are determined as a result of thecontrol section 1 repeating rotation of thebelt driving roller 25 and calculation of the correction values α. As a result of this, it is possible to acquire the roller correction tables that are illustrated by way of example inFig. 7 , and correct movement errors caused by decentering of thebelt driving roller 25. Additionally, it is preferable that the correction values α are determined in a case in which the connection section of theendless belt 26 is not positioned at thebelt rotation roller 24 or thebelt driving roller 25. As a result of this, it is possible to eliminate the effects of transport errors caused by the thickness of theendless belt 26. -
Fig. 8 is a view that describes a belt phase of the endless belt. In the present description, the position of the belt point oforigin sensor 80 is set as a reference position of theendless belt 26. The position of themarker 81, as the point of origin position of theendless belt 26, moves as a result of rotational driving of thebelt driving roller 25. In the following description, a difference between themarker 81, as the point of origin position of theendless belt 26, and a reference position is represented by a belt phase D. -
Fig. 9 is a view that shows an example of a belt correction table. The belt correction table represents a relationship between a point of origin position of an endless belt and a movement error of the endless belt. In the present embodiment, a plurality of belt correction tables, which correspond to a plurality of printing conditions, are stored in thestorage section 5. - Point of origin positions (the positions of the markers 81) of the
endless belt 26 are shown using the belt phases D in the parameters in the rows of the belt correction table that is shown inFig. 9 , and reference movement amounts Kn are shown as predetermined movement amounts of theendless belt 26 in the parameters of the rows. Further, correction values σ of the movement amounts are shown in intersecting positions of the respective parameters (the belt phases D and the reference movement amounts Kn). - A belt correction table acquisition unit, which acquires belt correction tables, calculates correction values σ of movement amounts from the reference movement amounts Kn, by which the
control section 1 feeds out theendless belt 26 by driving (rotating) thebelt driving roller 25, and practical movement amounts of theendless belt 26, which are determined using the movementamount detection sensor 70. Correction values σ of at least a single circuit (an amount that is equivalent to 360°) of theendless belt 26 are determined as a result of thecontrol section 1 repeating rotation of thebelt driving roller 25 and calculation of the correction values σ. As a result of this, it is possible to acquire the belt correction tables that are illustrated by way of example inFig. 9 , and correct movement errors caused by the thickness of theendless belt 26. Additionally, at the time of acquiring the belt correction tables, it is possible to acquire correction values σ in which transport errors caused by decentering of thebelt driving roller 25 are eliminated, by determining the position (the angle θ) of the driving shaft point of origin of thebelt driving roller 25 and taking the roller correction table into consideration. - In the present embodiment, a roller correction table and a belt correction table that were acquired by driving the
printing apparatus 100 using printing conditions of "clear", "medium type A" and "tension mode" are illustrated by way of example, but the printing conditions are not limited to these printing conditions. For example, the correction values α and σ of the belt correction tables and the roller correction tables differ depending on printing conditions such as the printing quality, which is represented by "clear", "fast", or the like, the medium type to be used as arecording medium 95, a condition relating to the tension when transporting arecording medium 95, which is represented by the "tension mode", the "slack mode", or the like, and the like. Therefore, theprinting apparatus 100 of the present embodiment includes roller correction tables and belt correction tables that correspond to printing conditions that are stipulated at the time of printing. To explain in more detail, a plurality of roller correction tables and a plurality of belt correction tables, which are acquired by driving theprinting apparatus 100 on the basis of these printing conditions, are included in thestorage section 5. - The
control section 1 of theprinting apparatus 100 selects a roller correction table and a belt correction table that match the printing conditions stipulated at the time of printing. - To explain in more detail, in a case in which printing conditions that include printing quality are stipulated at the time of printing, the
control section 1 selects a roller correction table and a belt correction table that match the printing conditions including the stipulated printing quality, from the plurality of roller correction tables and the plurality of belt correction tables that are saved in thestorage section 5 by performing acquisition including the printing quality as a parameter. As a result of this, it is possible to obtain correction values α and σ that include movement errors of theendless belt 26 caused by differences in the printing velocity, which depends on the printing quality. - In a case in which printing conditions that include the medium type are stipulated at the time of printing, the
control section 1 selects a roller correction table and a belt correction table that match the printing conditions including the stipulated medium type, from the plurality of roller correction tables and the plurality of belt correction tables that are saved in thestorage section 5 by performing acquisition including the medium type of arecording medium 95 as a parameter.

Fig. 10 is a flowchart that describes a printing operation of the printing apparatus. A printing operation of theprinting apparatus 100 will be described with reference toFigs. 4 and10 . - In Step S1, printing data is received. The
CPU 3 receives printing data to record an image on arecording medium 95 and stipulated conditions from theexternal apparatus 6, and saves the printing data and printing conditions in thestorage section 5. - In Step S2, the selection of correction tables is performed. The
CPU 3 selects a roller correction table and a belt correction table that match the printing conditions received in Step S1 from a plurality of roller correction tables and a plurality of belt correction tables, which are saved in thestorage section 5 and are acquired by setting various printing conditions as parameters. For example, the printing quality, which is represented by "clear", "fast", or the like, the medium type to be used as arecording medium 95, the tension when transporting the recording medium, which is represented by a "tension mode", a "slack mode", or the like, are included as the printing conditions. For example, in a case in which the received printing conditions are "clear", "medium type A" and "tension mode", theCPU 3 selects the roller correction table that is shown inFig. 7 and the belt correction table that is shown inFig. 9 . - In Step S3, a feeding amount of the
belt driving roller 25 is calculated. The control section 1 (the CPU 3) calculates a rotation amount of thebelt driving roller 25 on the basis of the roller correction table and the belt correction table. To explain in more detail, theCPU 3 calculates a point of origin position (an angle θ) of thebelt driving roller 25 and a point of origin position (a belt phase D) of theendless belt 26 by receiving signals that are output from the belt point oforigin sensor 80 and the driving shaft point oforigin sensor 85.

The feed out amount is a value in which a correction value α that is determined from the angle θ and a reference movement amount Kn, and a correction value σ that is determined from the belt phase D and the reference movement amount Kn, are added to the reference movement amount Kn. - In Step S4, the
recording medium 95 is transported and ink is discharged. Thecontrol section 1 moves theendless belt 26 by rotating thebelt driving roller 25 by the feed out amount that was calculated in Step S3, as a result of controlling the driving of thebelt driving roller 25. As a result of this, therecording medium 95, which is mounted on theendless belt 26, is transported in the transport direction. Further, thecontrol section 1 discharges ink from thedischarge head 42 toward therecording medium 95 while moving thecarriage 43 in a direction that intersects the transport direction of therecording medium 95, by controlling thecarriage movement section 41 and thedischarge head 42. - In Step S5, it is determined whether or not there is subsequent line of printing data. The
CPU 3 determines whether or not there is a subsequent line of printing data by referring to the printing data that is saved in thestorage section 5. In a case in which there is a subsequent line of printing data (Step S5: Yes), the process returns to Step S3 and the processes from Step S3 to Step S5 are repeated. In a case in which there is not a subsequent line of printing data (Step S5: No), thecontrol section 1 finishes the printing operation of theprinting apparatus 100. - As a result of the above-mentioned steps, since the movement accuracy of the
endless belt 26 and the transport accuracy of arecording medium 95, which is mounted on theendless belt 26, is improved, it is possible to improve the printing quality of an image that is formed on therecording medium 95. - In the abovementioned manner, according to the
