Abstract
Description
- The present invention relates to a cutting mechanism included in a recording apparatus such as a printer.
- As an example of a recording apparatus, there is a printer including a cutting mechanism which cuts a medium on which images such as characters and photographs are recorded to a desired size. JP-A-2016-55379 describes a cutting device which cuts a roll paper by a cutter unit having a rotary blade moving along a guide rail as an example of a cutting mechanism.
- In the cutting device described in JP-A-2016-55379, for example, there is a possibility that rattling is generated in the cutter unit when the cutter unit moves along the guide rail depending on how the cutter unit and the guide rail are attached to each other. If the cutter unit rattles, there is a fear that the medium cannot be accurately cut.
- An advantage of some aspects of the invention is to provide a cutting mechanism which can accurately cut a medium.
- Hereinafter, means and operation effects of the invention will be described.
- According to an aspect of the invention, there is provided a cutting mechanism including: a cutter blade that is capable of cutting a medium; a cutter unit to which the cutter blade is attached; and a guide rail that supports the cutter unit, in which the cutter blade is configured to cut the medium by the cutter unit moving in a traveling direction along the guide rail, the cutter unit has a first holding portion and a second holding portion, which are in contact with the guide rail, to be held to the guide rail, and the first holding portion and the second holding portion are disposed so as to interpose the cutter blade therebetween in the traveling direction.
- When the cutter unit is moved in the traveling direction and cuts the medium, a moment is generated in the cutter unit to rotate the cutter unit about the cutting position of the medium as a fulcrum by the cutter blade. According to the configuration, since the first holding portion and the second holding portion are disposed with the cutter blade interposed therebetween, it is possible to reduce rattling of the cutter unit caused by attempting to rotate about the cutting position as a fulcrum. Therefore, the medium can be accurately cut.
- In the cutting mechanism, it is preferable that the first holding portion and the second holding portion be disposed so as to interpose the guide rail therebetween.
- According to the configuration, since the first holding portion and the second holding portion are disposed so as to interpose the guide rail therebetween, rattling of the cutter unit can be reduced.
- In the cutting mechanism, it is preferable that the first holding portion be disposed behind the cutter blade in the traveling direction, and a distance between the first holding portion and the cutter blade in the traveling direction be configured to be longer than a distance between the second holding portion and the cutter blade in the traveling direction.
- According to the configuration, since the first holding portion is disposed at a position farther than the second holding portion with respect to the cutter blade in the traveling direction, rattling of the cutter unit can be further reduced.
- In the cutting mechanism, it is preferable that the guide rail be configured with a rack gear, the cutter unit have a driving gear disposed so as to mesh with the rack gear, and the driving gear mesh with the rack gear to rotate when the cutter unit moves in the traveling direction, and the cutter blade be configured to rotate as the driving gear rotates when the cutter unit moves in the traveling direction.
- According to the configuration, the medium is likely to be cut by the cutter blade being rotated.
- In the cutting mechanism, it is preferable that the first holding portion be configured with a pinion gear that is capable of meshing with the rack gear.
- According to the configuration, since the pinion gear as the first holding portion meshes with the rack gear, rattling of the cutter unit can be reduced as compared with a case where the first holding portion is a roller, for example.
- The invention will be described with reference to the accompanying drawings, wherein like numbers reference like elements.

- As illustrated in
FIG. 1 , the recording apparatus 11 has a rectangularparallelepiped housing 12. The recording apparatus 11 includes arecording unit 20 that records images such as characters and photographs on the medium S and afirst support member 31 and asecond support member 32 that support the medium S in thehousing 12. The recording apparatus 11 includes atransport unit 40 which transports the medium S and acutting mechanism 50 which cuts the medium S recorded by therecording unit 20 in thehousing 12. In other words, therecording unit 20, the first andsecond support members transport unit 40, and thecutting mechanism 50 are accommodated in thehousing 12. - In the
housing 12, for example, a roll body R on which a medium S as a sheet is wound in a roll form is disposed. The roll body R is disposed behind an inside of thehousing 12 which is on the right side inFIG. 1 . The roll body R is rotatably supported by ashaft 13 provided so as to extend in a width direction X of the medium S. In this embodiment, as theshaft 13 is rotated in the counterclockwise direction inFIG. 1 , the medium S is unwound from the roll body R. The unwound medium S is transported by thetransport unit 40 and discharged from the inside of thehousing 12 to the outside of thehousing 12 through adischarge port 15 opening on thefront surface 14 of thehousing 12. In other words, in this embodiment, the direction from a rear side to a front side of thehousing 12, the direction from a right side to a left side inFIG. 2 is the transport direction Y of the medium S transported by thetransport unit 40. Thefront surface 14 of thehousing 12 is a surface having a spread in the vertical direction Z and the width direction X. - The
recording unit 20 includes ahead 21 which ejects liquid such as ink, for example, toward the medium S and acarriage 22 which mounts thehead 21. Thecarriage 22 is supported by aframe 16 which is provided in thehousing 12 and aguide shaft 17 which is attached to theframe 16. Theguide shaft 17 extends in the width direction X of the medium S. Thecarriage 22 is movable along theguide shaft 17. In other words, thecarriage 22 is movable in the width direction X. By moving thecarriage 22 along theguide shaft 17, thehead 21 can eject liquid onto the medium S over the entire region in the width direction X. - The first and
second support members first support member 31 is disposed on the upstream side of thesecond support member 32 in the transport direction Y and guides the medium S unwound from the roll body R toward therecording unit 20. Thesecond support member 32 is disposed to face thehead 21 of therecording unit 20. - The
transport unit 40 transports the medium S unwound from the roll body R toward thedischarge port 15 from the inside of thehousing 12 so as to be along the first andsecond support members transport unit 40 has a firsttransport roller pair 41, a secondtransport roller pair 42, a thirdtransport roller pair 43, and a fourth transport roller pair 44 in order from the upstream side to the downstream side in the transport direction Y. The firsttransport roller pair 41 is disposed on the upstream side of thehead 21 in the transport direction Y and is disposed at a position between thefirst support member 31 and thesecond support member 32. The second, third, and fourthtransport roller pairs head 21 in the transport direction Y. - The first, second, third, and fourth
transport roller pairs driving roller 45 which can be driven and rotated by a motor (not illustrated), a drivenroller 46 which can be driven and rotated with respect to the rotation of thedriving roller 45. The first, second, third, and fourthtransport roller pairs driving roller 45 and the drivenroller 46. Thedriving roller 45 is disposed so as to contact the medium S from below. The drivenroller 46 is disposed so as to be in contact with the medium S from above. In other words, the drivenroller 46 in the second, third, and fourthtransport roller pairs rollers 46 in the second, third, and fourthtransport roller pairs transport roller pairs - The
cutting mechanism 50 is disposed between the thirdtransport roller pair 43 and the fourth transport roller pair 44 in the transport direction Y. The medium S cut by thecutting mechanism 50 is transported by the fourth transport roller pair 44 and discharged from thedischarge port 15. The recording apparatus 11 according to this embodiment is configured such that the interval in the vertical direction Z at the opening of thedischarge port 15 is relatively small to the extent that the user cannot insert the hand into thehousing 12 from thedischarge port 15. - The recording apparatus 11 in this embodiment is normally used in a state of being installed on a horizontally spreading floor surface. The
housing 12 of the recording apparatus 11 is provided in a rectangular parallelepiped shape such that thefront surface 14 thereof crosses the floor surface and ideally is orthogonal to the floor surface. At this time, an orthogonal coordinate system including three axes of X axis, Y axis, and Z axis is considered, the floor surface on which the recording apparatus 11 is installed is a plane including the X-axis and the Y-axis, and a coordinate system is set so that thefront surface 14 of thehousing 12 becomes a plane including an X-axis and a Z-axis. Then, the width direction X coincides with the direction in which the X-axis extends, the transport direction Y coincides with the direction in which the Y-axis extends, and the vertical direction Z coincides with the direction in which the Z-axis extends. The X-axis extending in the width direction X, the Y-axis extending in the transport direction Y, and the Z-axis extending in the vertical direction Z have a relationship of being orthogonal to each other. In other words, in this embodiment, the width direction X, the transport direction Y, and the vertical direction Z respectively indicate three different directions from each other. - Next, the
cutting mechanism 50 will be described. - As illustrated in
FIG. 2 , thecutting mechanism 50 has acutter blade 51 for cutting the medium S, acutter unit 70 to which thecutter blade 51 is attached, and aguide frame 60 which supports thecutter unit 70. Theguide frame 60 extends in the width direction X so as to be longer than the roll body R that can be loaded by the recording apparatus 11. In other words, the longitudinal direction of theguide frame 60 coincides with the width direction X. Thecutter unit 70 can reciprocate along theguide frame 60. Thecutting mechanism 50 cuts the medium S by thecutter blade 51 as thecutter unit 70 moves along theguide frame 60. For convenience of explanation, in the width direction X, the left side inFIG. 2 is set as the +X side and the right side as the opposite side thereto is set to the −X side. In this embodiment, as illustrated inFIG. 2 , in theguide frame 60, the end portion on the +X side in the width direction X is set as the home position HP of thecutter unit 70. - The
guide frame 60 is formed by bending a sheet metal. Theguide frame 60 is formed in a claw-like shape when viewed from the width direction X. Theguide frame 60 has abottom wall 61 and afront wall 62 and arear wall 63 which bend upward from thebottom wall 61 and extend. Thefront wall 62 is located on the downstream side of therear wall 63 in the transport direction Y and extends from thebottom wall 61 so that its length is shorter than therear wall 63 in the vertical direction Z. - The
guide frame 60 has arack gear 64 extending in the width direction X. Therack gear 64 is attached to a surface of therear wall 63 of theguide frame 60 which is on the downstream side in the transport direction Y. Therack gear 64 is disposed along an upper edge of therear wall 63 and is provided so that the length in the width direction X is slightly shorter than theguide frame 60. Therack gear 64 has atooth 65 over the width direction X at a portion on the lower side thereof. Therack gear 64 has agroove 66 in the width direction X for guiding the movement of thecutter unit 70 in a portion on the upper side thereof. - As illustrated in
FIG. 2 andFIG. 3 , thecutter unit 70 has a holdingbody 71 which holds thecutter blade 51 and a movingbody 72 which is held on theguide frame 60. Thecutter unit 70 illustrated inFIGS. 2 and 3 is located at the home position HP. The holdingbody 71 and the movingbody 72 are fixed to each other so as to be capable of being handled integrally. The holdingbody 71 and the movingbody 72 are fixed so that the portions thereof are overlapped with each other when viewed from the transport direction Y. Specifically, the holdingbody 71 and the movingbody 72 are disposed so that the lower portion of the holdingbody 71 and the upper portion of the movingbody 72 overlap each other in the vertical direction Z. - The holding
body 71 is attached to a surface of the movingbody 72 on the downstream side in the transport direction Y. The holdingbody 71 has amedium path 73 extending in the width direction X at a position above the movingbody 72 in the vertical direction Z. Themedium path 73 is a path through which the medium S passes through the holdingbody 71 when thecutter unit 70 moves in the width direction X along theguide frame 60. The portion of themedium path 73 on the −X side in the width direction X is anintroduction port 74 for introducing the medium S into themedium path 73. So as to facilitate the introduction of the medium S into themedium path 73, theintroduction port 74 is configured so that the opening in the vertical direction Z gradually increases from the +X side to the −X side in the width direction X. - The holding
body 71 holds thecutter blade 51 at a position in themedium path 73 in the middle thereof. In other words, when thecutter unit 70 moves in the width direction X, themedium path 73 guides the medium S toward thecutter blade 51. Thecutter blade 51 is disposed on the +X side of theintroduction port 74 in the width direction X and is positioned adjacent to theintroduction port 74. Thecutter blade 51 is configured with a disk-shapeddriving blade 52 and a drivenblade 53. Thedriving blade 52 and the drivenblade 53 are rotatably attached to the holdingbody 71. Thedriving blade 52 and the drivenblade 53 are provided so as to be lined up in the vertical direction Z and disposed so as to interpose themedium path 73 therebetween. Thedriving blade 52 is positioned below the drivenblade 53 in the vertical direction Z and is positioned on the downstream side of the drivenblade 53 in the transport direction Y. - The
cutter blade 51 is held by the holdingbody 71 in a state where the cutting edge which is the upper portion of thedriving blade 52 and the cutting edge which is a lower side portion of the drivenblade 53 are overlapped with each other when viewed from the transport direction Y. The cutting edge of thedriving blade 52 and the cutting edge of the drivenblade 53 are in contact with each other at a cutting position Q which is a position closer to the −X side in the width direction X among a portion in which the cutting edges overlap each other. Thedriving blade 52 in this embodiment is held by the holdingbody 71 in a posture in which the rotation shaft thereof is inclined by a predetermined angle with respect to the drivenblade 53 extending in the transport direction Y. Thecutter blade 51 cuts the medium S at the cutting position Q where the cutting edges of thedriving blade 52 and the drivenblade 53 are in contact with each other as thedriving blade 52 and the drivenblade 53 are rotated. In other words, when thecutter unit 70 moves from the +X side to the −X side in the width direction X, thecutting mechanism 50 interposes the medium S passing through themedium path 73 between therotating driving blade 52 and the drivenblade 53 and cut the medium S. In this embodiment, a direction from +X side toward −X side in the width direction X is set to as a traveling direction in which thecutter unit 70 is traveled when thecutter blade 51 cuts the medium S. In other words, in thecutter unit 70, +X side in the width direction X becomes a rear side in the traveling direction and −X side in the width direction X becomes a front side in the traveling direction. Thecutting mechanism 50 in this embodiment returns to the home position HP by moving from the −X side to the +X side after cutting the medium S by moving from the +X side to the −X side in the width direction X. - The holding
body 71 has alever 75 on the top thereof for connecting thecarriage 22 of therecording unit 20 and thecutter unit 70 with each other. Thelever 75 is engageable with an engaging portion (not illustrated) provided on thecarriage 22, for example, a claw extending from thecarriage 22. In other words, by connecting thecutter unit 70 to thecarriage 22 via thelever 75, thecutter unit 70 can move in the width direction X according to the movement of thecarriage 22. Thelever 75 is configured to be switchable between an engaged state in which thelever 75 engages with the engaging portion and an unlocked state in which thelever 75 is not engaged with the engaging portion by an actuator, a motor, or the like. In this embodiment, for example, when therecording unit 20 records on the medium S, thelever 75 is in the unlocked state, and when thecutting mechanism 50 cuts the medium S, thelever 75 is in the engaged state. When thelever 75 is in the unlocked state, thecutter unit 70 is not moved according to the movement of thecarriage 22, and when thelever 75 is in the engaged state, thecutter unit 70 moves according to the movement of thecarriage 22. - As illustrated in
FIGS. 3 and 4 , the movingbody 72 has afirst roller 81, asecond roller 82, and athird roller 83 disposed to interpose thefront wall 62 of theguide frame 60 at the lower portion thereof. The first andsecond rollers front wall 62 so that peripheral surfaces thereof are in contact with a surface on the downstream side in the transport direction Y. Thethird roller 83 is disposed on thefront wall 62 so that peripheral surface thereof is in contact with a surface on the upstream side in the transport direction Y. Thefirst roller 81 is located at the end portion which is on the +X side of the movingbody 72 and thesecond roller 82 is located at the end portion at the −X side in the width direction X. Thethird roller 83 is located between thefirst roller 81 and thesecond roller 82 in the width direction X. The first, second, andthird rollers front wall 62 when the movingbody 72 is moved in the width direction X. In other words, the first, second, andthird rollers cutter unit 70 along thefront wall 62. - As illustrated in
FIGS. 4 and 5 , the movingbody 72 has afourth roller 84 and afifth roller 85 disposed on the upper portion thereof so that a portion of the movingbody 72 fits in thegroove 66 of therack gear 64. The fourth andfifth rollers bottom surface 67 of thegroove 66. Thefourth roller 84 is located at the end portion on the −X side in the width direction X in the movingbody 72, and thefifth roller 85 is located at the end portion on the +X side in the width direction X. In other words, in the traveling direction of thecutter unit 70, thefourth roller 84 is located in front of thecutter blade 51, and thefifth roller 85 is located behind thecutter blade 51. Thecutter unit 70 in this embodiment is configured such that the distance between thefifth roller 85 and thecutter blade 51 in the traveling direction is larger than the distance between thefourth roller 84 and thecutter blade 51 in the traveling direction. - The
fourth roller 84 is located above thesecond roller 82, and thefifth roller 85 is located above thefirst roller 81. The fourth andfifth rollers bottom surface 67 of thegroove 66 when the movingbody 72 moves in the width direction X. In other words, the fourth andfifth rollers cutter unit 70 along thegroove 66 of therack gear 64. In other words, thecutter unit 70 moves along therack gear 64. In summary, the first, second, third, fourth andfifth rollers cutter unit 70 along theguide frame 60. - The moving
body 72 has afirst pinion gear 91 and asecond pinion gear 92 that can mesh withteeth 65 of therack gear 64. In other words, thecutter unit 70 has a plurality of pinion gears. The first and second pinion gears 91 and 92 are rotatably attached to the movingbody 72. The first and second pinion gears 91 and 92 haveteeth first pinion gear 91 is disposed on the −X side with respect to thesecond pinion gear 92 in the width direction X. Thefirst pinion gear 91 is located directly below thecutter blade 51. Thesecond pinion gear 92 is located behind thecutter blade 51 in the traveling direction of thecutter unit 70. In this embodiment, thesecond pinion gear 92 is disposed such that the distance between thesecond pinion gear 92 and thecutter blade 51 in the traveling direction of thecutter unit 70 is larger than the distance between thefourth roller 84 and thecutter blade 51. When thecutter unit 70 moves along theguide frame 60, the first and second pinion gears 91 and 92 rotate while meshing with therack gear 64. - As illustrated in
FIG. 5 , thecutter unit 70 is attached to therack gear 64 by the fourth andfifth rollers rack gear 64 in the vertical direction Z. In other words, in this embodiment, therack gear 64 functions as a guide rail for supporting thecutter unit 70. In this embodiment, the fourth andfifth rollers rack gear 64 so that thecutter unit 70 is held by therack gear 64. It can also be said that thecutter unit 70 is held by therack gear 64 via the fourth andfifth rollers - The
cutter unit 70 has a transmission gear (not illustrated) which transmits the rotation of thefirst pinion gear 91 to thedriving blade 52. In other words, when thecutter unit 70 moves in the width direction X along theguide frame 60, thedriving blade 52 is configured to rotate according to the rotation of thefirst pinion gear 91. In this embodiment, thefirst pinion gear 91 functions as a driving gear that rotates thedriving blade 52. InFIG. 3 of this embodiment, when thecutter unit 70 moves from the +X side to the −X side in the width direction X, that is, when moving in the traveling direction, thedriving blade 52 is configured to rotate counterclockwise. The drivenblade 53 is driven to rotate by the rotation of thedriving blade 52 as the cutting edge thereof is in contact with the cutting edge of thedriving blade 52. - Next, the operation of the
cutting mechanism 50 included in the recording apparatus 11 configured as described above will be described. - As illustrated in
FIG. 5 , when thecutting mechanism 50 cuts the medium S, thecutter unit 70 moves in a direction from the +X side to the −X side in the width direction X according to the movement of thecarriage 22 connected by thelever 75, that is, in the traveling direction. Thecutter unit 70 moves in the traveling direction along therack gear 64 and thus the medium S is cut by thecutter blade 51. At this time, a force directed from the +X side to the −X side in the width direction X is applied from thecarriage 22 of therecording unit 20 to thelever 75 located on the upper portion of the holdingbody 71 in thecutter unit 70. Therefore, when the medium S is cut, in thecutter unit 70, thelever 75 is set as a force point and the cutting position Q where thecutter blade 51 and the medium S is in contact with each other is set to as a fulcrum and there is a case where a moment is generated around the fulcrum. When a moment is generated around the cutting position Q, thecutter unit 70 tries to rotate about the cutting position Q as a fulcrum in traveling direction thereof. Accordingly, there is a fear that rattling is generated in thecutter unit 70 with respect to therack gear 64. In this regard, thecutting mechanism 50 according to this embodiment includes the first holding portion and the second holding portion for reducing rattling of thecutter unit 70. - In a case where the
cutter unit 70 moves in the traveling direction in order to cut the medium S, thecutter unit 70 tries to rotate in a direction counterclockwise inFIG. 5 with the cutting position Q as a fulcrum. In other words, thecutter unit 70 tries to rotate so that the rear portion in the traveling direction moves upward so that the front portion in the traveling direction moves downward. At this time, thesecond pinion gear 92 is strongly pressed against therack gear 64 from below, and thefourth roller 84 is strongly pressed against therack gear 64 from above. In other words, thesecond pinion gear 92 and thefourth roller 84 hold thecutter unit 70 in therack gear 64 so as to suppress the rotation of thecutter unit 70. Therefore, in this embodiment, thesecond pinion gear 92 functions as a first holding portion and thefourth roller 84 functions as a second holding portion. In summary, rattling of thecutter unit 70 is reduced by the first holding portion and the second holding portion disposed so as to interpose thecutter blade 51 in the traveling direction. - According to the embodiment described above, the following effects can be obtained.
- (1) When the
cutter unit 70 moves in the traveling direction to cut the medium S, a moment for rotating thecutter unit 70 about the cutting position Q of the medium S by thecutter blade 51 as a fulcrum is generated in thecutter unit 70. In this respect, in thecutting mechanism 50, the second pinion gear (first holding portion) 92 and the fourth roller (second holding portion) 84 are disposed with thecutter blade 51 therebetween. Therefore, rattling of thecutter unit 70 generated by attempting to rotate about the cutting position Q as a fulcrum can be reduced. Therefore, the medium S can be accurately cut. - (2) Since the second pinion gear (first holding portion) 92 and the fourth roller (second holding portion) 84 are disposed so as to interpose the rack gear (guide rail) 64, rattling of the
cutter unit 70 can be reduced. - (3) In the traveling direction of the
cutter unit 70, the second pinion gear (first holding portion) 92 is disposed at a position further separated from thecutter blade 51 than the fourth roller (second holding portion) 84. Therefore, rattling of thecutter unit 70 can be further reduced. In other words, by increasing the distance between the cutting position Q and the fourth roller (second holding portion) 84 in the traveling direction, thecutting mechanism 50 effectively reduces the rotation of thecutter unit 70 about the cutting position Q as a fulcrum. - (4) The
cutter blade 51 is configured to rotate as the first pinion gear (driving gear) 91 is rotated when thecutter unit 70 moves in the traveling direction. Therefore, by rotating thecutter blade 51, the medium S can be likely to be cut. - (5) Since the
first pinion gear 91 as the first holding portion meshes with therack gear 64, rattling of thecutter unit 70 can be reduced as compared with, for example, a case where the first holding portion is a roller. - (6) The first holding portion is provided as a pinion gear (second pinion gear 92). Further, a plurality of pinion gears including the
first pinion gear 91 and thesecond pinion gear 92 mesh with therack gear 64. Accordingly, when thecutter unit 70 moves along therack gear 64, it is possible to reduce the possibility of tooth jumping of thefirst pinion gear 91 with respect to therack gear 64. By reducing the tooth jumping of thefirst pinion gear 91, since thecutter blade 51 rotates at a fixed cycle, the medium S can be accurately cut. - (7) The
cutting mechanism 50 has afirst pinion gear 91 and afifth roller 85. Therefore, even in a case where thecutter unit 70 rotates in the clockwise direction inFIG. 5 about the cutting position Q as a fulcrum, the rattling can be reduced. - The embodiment described above may be modified as follows. In addition, the following modification examples may be combined as appropriate.
- The first holding portion may be, for example, a roller. In this case, it is preferable that the
rack gear 64 have a groove instead of thetooth 65. - The guide rail is not limited to the
rack gear 64, but may be a simple rail. In this case, it is preferable that thefirst pinion gear 91 and thesecond pinion gear 92 be rollers. Thecutter blade 51 is not limited to a rotating configuration, and thecutter blade 51 may be a fixed blade. In this case, it is not necessary for thefirst pinion gear 91 to transmit the driving force for rotation to thecutter blade 51. In other words, the driving gear may not be provided. - The
driving blade 52 may be configured to rotate by a motor or the like. In this case, it is not necessary for thefirst pinion gear 91 to transmit the driving force for rotation to thecutter blade 51. In other words, the driving gear may not be provided. - In the transport direction Y, the distance between the
second pinion gear 92 functioning as the first holding portion and thecutter blade 51 may be equal to that between thefourth roller 84 functioning as the second holding portion and thecutter blade 51 or the distance therebetween may be small than that. - The
fifth roller 85 may not be provided. - The
cutter unit 70 may be configured to move by a separate driving source such as a motor. Even in such a case, there is a less fear that rattling occurs in thecutter unit 70. - The recording apparatus 11 may be a fluid ejecting apparatus that performs recording by ejecting or discharging another fluid other than ink (including a liquid, a liquid body in which particles of the functional material are dispersed or mixed in a liquid, a fluid body such as a gel, a solid that can be injected by flowing as a fluid). For example, the recording apparatus 11 may be a fluid ejecting apparatus that performs recording by ejecting a liquid body containing dispersed or dissolved materials such as electrode material and color material (pixel material) used for production or the like of liquid crystal display, electroluminescence (EL) display, or surface emitting display. In addition, the recording apparatus 11 may be a fluid ejecting apparatus that ejects a fluid body such as a gel (for example, a physical gel), a powdery particle ejecting apparatus (such as toner jet type recording apparatus) that ejects a solid, such as a powder (granular material) may be used. The present invention can be applied to any one of the fluid ejecting apparatuses. In the present specification, the term “fluid” means, for example, a liquid (including inorganic solvent, organic solvent, solution, liquid resin, liquid metal (metal melt), or the like), a liquid body, a fluid body, a granular body (including granular body and powder body) and the like.
