(First embodiment)
Hereinafter, a recording medium transport tray (hereinafter simply referred to as a tray) 100 and a recording apparatus 200 according to the first embodiment will be described with reference to FIGS. 1 and 2.

  FIG. 1 is a rear perspective view of a recording apparatus 200 according to the first embodiment. In the figure, a schematic configuration diagram showing a schematic configuration of the recording apparatus 200 is shown. A recording apparatus 200 shown in FIG. 1 shows a state in which a lens sheet L1 as another recording medium is loaded in the recording apparatus 200 using the tray 100. FIG. 2 is a perspective view showing the configuration of the tray according to the first embodiment. The drawing shows an exploded perspective view in which the tray 100, the lens sheet L1, and the recording apparatus 200 are drawn separately to make the configuration of the tray 100 easy to understand. In FIG. 1, the direction of the arrow X, which is the direction in which the lens sheet L1 loaded in the recording apparatus 200 travels, is the front (front side), and the opposite direction is the rear (rear side). In addition, the direction of the arrow Y that is the right hand direction from the rear to the front is the right side (right side), and the left hand direction that is the opposite direction is the left side (left side).

  The following explanation will be given with the direction of the arrow Z as the upper side (upper side) and the opposite direction as the lower side (lower side).

The lens sheet L1 is configured so that an image recorded on the image forming layer 7 can be viewed through the lenticular lens 6. Therefore, for example, when an image having a parallax is recorded on the image forming layer 7 in correspondence with the arrangement pitch or focal length of the lenticular lens 6 and this image is viewed from the lenticular lens 6 side, an image with a three-dimensional effect is obtained. Or different images depending on the viewing angle. The lens sheet L1 may be configured to directly record on the resin portion on the surface opposite to the side on which the lenticular lens 6 is formed without forming the image forming layer 7.

  A paper feed opening 8 for feeding the tray 100 on which the lens sheet L1 is placed into the housing 1 is formed on the rear side surface of the housing 1, and a paper feed opening is provided on the front side surface. A paper discharge opening 9 for discharging the tray 100 on which the lens sheet L1 supplied from the opening 8 is placed is formed. The tray 100 supplied to the recording apparatus 200 from the paper supply opening 8 is conveyed forward by the paper supply roller 3 and the paper discharge roller 4 with the lens sheet L1 placed thereon, and recording is performed by the recording head 5. After that, the paper is discharged from the paper discharge opening 9 to the outside of the recording apparatus 200.

  The tray support guide 2 is disposed at a position where the upper surface of the tray guide surface 10 is substantially the same as the upper portion of the paper feed roller 3 and the paper discharge roller 4. The tray support guide 2 has a rectangular plate-like body as a whole, and the front-rear direction is provided from a position protruding rearward of the paper feed opening 8 to a position in front of the paper feed roller 3. Moreover, about the width direction on either side, it is the width | variety which can support the tray 100 mounted over the full width. The tray support guide 2 is attached to the housing 1 or a structure such as an internal frame with a configuration not shown.

  The tray support guide 2 is formed from a plate-like body made of resin or the like, and the tray guide surface 10 is formed as a guide portion 11 that guides the transport direction of the tray 100 placed on the tray guide surface 10. Yes. The guide portion 11 is composed of a plurality of ridge portions 12. The ridge portion 12 is formed in the same shape as the lenticular lens of a guide portion lens sheet (not shown) as a predetermined recording medium having a lenticular lens having a predetermined pitch different from the lenticular lens 6 of the lens sheet L1. That is, the ridge portion 12 is formed in the same shape as the lenticular lens of the guide portion lens sheet which is a lens sheet that is placed on the tray support guide 2 and conveyed instead of the tray 100. That is, the ridges 12 having the same shape as the lens elements forming the lenticular lens of the guide part lens sheet have the same pitch as the arrangement pitch of the lenticular lenses of the guide part lens sheet, or the width of the tray 100 or They are juxtaposed over a wider width. That is, the ridge portion 12 is an engaging portion that can engage with the lenticular lens along the linear direction of the lenticular lens of the guide portion lens sheet.

  In the present embodiment, the guide part lens sheet and the lens sheet L1 are arranged such that the arrangement pitch of the lenticular lenses of the guide part lens sheet is larger than that of the lenticular lens 6 of the lens sheet L1. Further, the longitudinal direction of the ridge 12, that is, the generatrix (ridgeline) direction of the ridge 12 is formed along a predetermined conveyance direction of the lens sheet L 1, that is, a direction orthogonal to the main scanning direction.

  In the present embodiment, the guide portion 11 is configured by attaching the guide portion lens sheet to the upper surface of the tray support guide 2 with the lenticular lens side of the guide portion lens sheet facing upward. Thus, since the guide part 11 is formed by sticking the lens sheet for the guide part to the tray support guide 2, the guide part 11 can be easily provided on the tray support guide 2. When the tray support guide 2 is formed by resin molding, a mold surface corresponding to the guide portion 11 is formed in advance on the molding die so that the guide portion 11 is molded integrally with the tray support guide 2. Also good. Further, the tray support guide 2 may be formed of a metal plate. In this case, the guide part 11 can be formed by cutting a metal plate.

  As shown in FIG. 2, the tray 100 has a rectangular plate-like body as a whole, has the same shape as the lens sheet L1 to be placed or a size larger than that, and can be placed on the entire surface of the lens sheet L1. It has become. The upper surface of the tray 100, that is, the placement surface 13 on which the lens sheet L1 is placed is engaged with the lenticular lens 6 of the lens sheet L1, and a plurality of ridges 14 for positioning the lens sheet L1 are provided. The engaging portion 15 is formed. On the other hand, on the lower surface of the tray 100, a guided portion 17 having a plurality of ridge portions 16 that engage with the guide portion 11 provided in the tray support guide 2 described above is provided.

  The engaging portion 15 is formed in the same shape as the lenticular lens 6 of the lens sheet L1. That is, the convex strip 14 has a linear body having the same shape as the lens element 18 forming the lenticular lens 6 and spans a width wider than the width of the lens sheet L1 at the same pitch as the arrangement pitch of the lenticular lens 6. It is installed side by side. The longitudinal direction of the ridges 14, that is, the generatrix (ridgeline) direction of the ridges 14, is formed along a predetermined conveyance direction of the lens sheet L1, that is, a direction orthogonal to the main scanning direction.

  The guided portion 17 is formed in the same shape as the guide portion 11. That is, the ridge portion 16 has a linear shape having the same shape as the ridge portion 12 of the guide portion 11, and is arranged side by side over the entire width of the lower surface of the tray 100 at the same pitch as the arrangement pitch of the ridge portions 12. Has been. The longitudinal direction of the ridge 16, that is, the generatrix (ridgeline) direction of the ridge 16 is along the same direction as the ridge 14 of the engaging portion 15, that is, the direction orthogonal to the main scanning direction. Is formed.

  By the way, in this embodiment, the engaging portion 15 of the tray 100 is configured by attaching a lens sheet L1 with the lenticular lens 6 facing the upper surface to the upper surface of the tray 100. Thus, the engaging part 15 can be easily provided in the tray 100 by forming the engaging part 15 by the lens sheet L1. Similarly to the engaging portion 15, the guided portion 17 is also configured by attaching the lenticular lens side of the guide portion lens sheet downward to the lower surface. When the tray 100 is formed by resin molding, a mold surface corresponding to the engaging portion 15 and the guided portion 17 is formed in advance in the molding die, and the engaging portion 15 and the guided portion 17 are connected to the tray 100. You may make it shape | mold integrally. Further, the tray 100 may be formed of a metal plate. In this case, the engaging portion 15 and the guided portion 17 can be formed by cutting the engaging portion 15 and the guided portion 17 by cutting the metal plate.

  A paper feed roller 3 and a paper discharge roller 4 are disposed before and after the recording head 5. The paper feed roller 3 and the paper discharge roller 4 are rotationally driven by a paper feed motor 19 and a paper discharge motor 20, respectively. On the upper side of the sheet feed roller 3, for example, three sheet feed-side driven rollers 21 that rotate following the rotation of the sheet feed roller 3 are provided in the left-right direction. Further, on the upper side of the paper discharge roller 4, for example, three paper discharge side driven rollers 22 that rotate following the paper discharge roller 4 are provided in the left-right direction. Accordingly, the lens sheet L1 supplied to the recording apparatus 200 from the paper feed opening 8 is disposed between the paper feed roller 3 and the paper feed side driven roller 21 together with the tray 100 on which the lens sheet L1 is placed, and the paper discharge roller 4 and the paper discharge roller 4. It is sandwiched between the paper-side driven rollers 22, receives the rotation of the paper feed roller 3 and the paper discharge roller 4, and is conveyed from the rear to the front. Then, after recording is performed on the conveyed lens sheet L 1 by the recording head 5, the recording sheet 5 is discharged from the discharge opening 9 to the outside of the recording apparatus 200.

  In front of the paper discharge roller 4, there is provided a paper discharge side tray support guide 23 that supports the lower surface of the tray 100 that is recorded by the recording head 5 and discharged from the paper discharge opening 9. The sheet discharge side tray support guide 23 prevents the conveyance tray 100 sent out from the sheet discharge roller 4 from bending downward so that the protruding line part 14 of the guided part 17 does not come off the protruding line part 12 of the guide part 11. Further, the upper surface 24 has the same height as the placement surface 13 of the tray support guide 2 or a slightly lower height, and the length in the front-rear direction is also set sufficiently long.

  A recording head 5 is disposed above the paper feed roller 3 and the paper discharge roller 4. The recording head 5 is attached to the lower surface of the carriage 25 and is configured as an ink jet recording head for discharging ink in the present embodiment. The carriage 25 is movably supported by a carriage guide 26 that extends in the left-right direction, and is attached to a timing belt 28 that is driven by a carriage motor 27. For this reason, when the timing belt 28 is rotationally driven in the left-right direction by the carriage motor 27, the recording head 5 can move in the left-right direction along the carriage guide 26 together with the carriage 25.

  Therefore, the conveyance of the lens sheet L1 in the sub-scanning direction, which is the conveyance direction of the lens sheet L1, is controlled by the paper feed roller 3 and the paper discharge roller 4, and the movement of the recording head 5 in the main scanning direction, that is, in the horizontal direction. Also, the recording head 5 can be moved to a predetermined position on the lens sheet L1, and an image can be recorded at a desired position on the lens sheet L1. The lens sheet L1 is placed on the tray support guide 2 so that the image forming layer 7 side faces the recording head 5 and the lenticular lens 6 side contacts the guide portion 11. That is, the recording head 5 performs recording on the image forming layer 7, and a recorded matter is produced in which the image recorded on the image forming layer 7 can be viewed from the lenticular lens 6 side.

  Recording on the lens sheet L1 by the recording apparatus 200 configured as described above is performed as follows. First, the lens sheet L1 is placed with the side of the lenticular lens 6 facing the tray 100. Since the engaging portion 15 and the lenticular lens 6 have the same shape, the lenticular lens 6 meshes with the engaging portion 15 in the lens sheet L1 placed on the tray 100. Therefore, the lens sheet L1 is in a state where the left and right direction (main scanning direction) is positioned by the engaging portion 15. That is, the engaging portion 15 constitutes an engaging portion that engages with the lenticular lens 6 along the linear direction of the lenticular lens 6 of the lens sheet L1 placed on the tray 100. That is, the lens sheet L1 is positioned so as not to rotate on the tray 100 or move left and right by the engaging portion 15.

  Then, the tray 100 on which the lens sheet L1 is placed is placed on the tray support guide 2 so that the guided portion 17 engages with the guide portion 11 provided on the tray support guide 2. In the guide portion 11 and the guided portion 17, the ridge portions 12 and the ridge portions 16 having the same shape are arranged in parallel at the same arrangement pitch. Therefore, the ridges 12 and the ridges 16 are engaged with each other in a state in which they can move in the front-rear direction without rattling in the left-right direction. In this way, the tray 100 is placed on the tray support guide 2 by placing the tray 100 on the tray support guide 2 so that the protrusions 16 of the guided portion 17 are fitted to the protrusions 12 of the guide portion 11. On the other hand, positioning in the left-right direction and rotation on the tray support guide 2 are prevented.

  Therefore, the tray 100 conveyed by the paper feed roller 3 and the paper discharge roller 4 is conveyed in a state in which a certain conveyance direction is maintained along the direction orthogonal to the main scanning direction, that is, the sub-scanning direction. . Further, as described above, the lens sheet L1 placed on the tray 100 is positioned by the engaging portion 15 so as not to move or rotate in the left-right direction on the tray 100. Therefore, the lens sheet L1 is conveyed in a fixed direction, and recording on the lens sheet L1 by the recording head 5 can be performed at a predetermined position.

  By the way, the guide part 11 provided in the tray support guide 2 is formed in the same shape as the lenticular lens of the guide part sheet lens having a lenticular lens having a larger pitch than the lenticular lens 6 of the lens sheet L1. Therefore, instead of the tray 100, when the guide unit sheet lens is placed on the tray support guide 2 toward the guide unit 11 on the lenticular lens side, the lenticular lens and the guide unit 11 of the guide unit lens sheet are separated from each other. The guide portion lens sheet is positioned in the left-right direction (main scanning direction) by the guide portion 11. That is, when the guide portion sheet lens is conveyed by the paper feed roller 3 and the paper discharge roller 4, the guide portion 11 guides the lenticular lens of the guide portion lens sheet in a direction orthogonal to the main scanning direction (sub scanning direction). It is conveyed in the state. Therefore, even when the guide lens sheet is directly placed on the tray support guide 2 and conveyed, and recording is performed by the recording head 5, recording on the guide lens sheet can be performed at a predetermined position.

  As described above, in the recording apparatus 200, the convex portion 12 of the guide portion 11 has the same shape as the lenticular lens of the guide portion lens sheet, so that the guide portion lens sheet is made to have a predetermined shape using the guide portion 11. It can be transported along the transport direction, and recording on the guide portion lens sheet can be performed at a predetermined position.

  Further, by configuring the engaging portion 15 of the tray 100 to engage with a lenticular lens having a pitch different from that of the guide portion lens sheet, a lens having a lenticular lens having a pitch different from that of the guide portion lens sheet. With respect to the sheet, the lens sheet having a lenticular lens having a different pitch from that of the guide lens sheet can be transported along a predetermined transport direction by placing the sheet on the tray 100 and transporting the sheet to a predetermined position. Recording can be performed. That is, it is possible to perform recording with one recording apparatus 200 while conveying lens sheets having lenticular lenses having different pitches in a predetermined conveying direction.

  Specifically, for example, the lens sheet for the guide part is a lens sheet having a 60 LPI (Lens Per Inch) lenticular lens in which 60 lens elements are arranged per inch, and the guide part 11 is a 60 LPI lenticular lens. It is assumed that it corresponds to the lens, and the guided portion 17 also corresponds to this guide portion 11. The engaging portion 15 corresponds to the lenticular lens 6 of the lens sheet L1 having a 100 LPI lenticular lens. As a result, when recording is performed on a 60 LPI lens sheet, it is possible to perform recording with high recording position accuracy by directly guiding the lens sheet to the tray support guide 2. Further, when recording is performed on a 100 LPI lens sheet, recording with high recording position accuracy can be performed by placing the lens sheet on the tray 100 and performing recording. Therefore, the tray 100 is set to 60 LPI for the guided portion 17 and the engaging portion 15 corresponding to the lenticular lens having the desired recording pitch is prepared for each pitch of the lenticular lens. Recording can be performed on a lens sheet of a plurality of lenticular lenses having a plurality of pitches by the recording apparatus 200 of the table.

  Further, by placing the lens sheet L1 on the tray 100 and transporting it, the distance between the lens sheet L1 and the ink ejection portion of the recording head 5 is shortened. Alternatively, by setting the thickness of the tray 100 to a predetermined thickness according to the thickness of the lens sheet L1, the distance between the ink ejection unit of the recording head 5 and the lens sheet L1 can be set to a predetermined distance. For this reason, it is possible to suppress the positional deviation that occurs until the ink ejected from the recording head 5 adheres to the lens sheet L1.

  Note that the pitch of the engaging portions 15 may be the same as that of the guide portions 11. That is, you may comprise the pitch of the engaging part 15 at the same pitch as the lenticular lens of the lens sheet for guide parts. Even in this case, the lens sheet placed on the tray 100 can be transported along a predetermined transport direction, and recording can be performed at a predetermined position. In addition, the distance between the lens sheet and the ink ejection portion of the recording head 5 can be shortened, and the positional deviation that occurs until the ink ejected from the recording head 5 adheres to the lens sheet can be suppressed.

(Detection of transport angle)
By the way, the guide part 11, the guided part 17, and the engaging part 15 are precisely along the predetermined conveying direction of the lens sheet L1, that is, the guide part 1, the guided part 17, and the engaging part 15 are in the main scanning direction. When it is provided so as to be orthogonal to (the direction orthogonal to the paper feed roller 3 and the paper discharge roller 4), recording can be performed at a predetermined position of the lens sheet L1. On the other hand, when the guide portion 11 and the like are provided in a state not orthogonal to the main scanning direction, the lens sheet L1 is conveyed obliquely with respect to a predetermined conveyance direction. As a result, as the lens sheet L1 is conveyed, the lens sheet L1 is conveyed while being displaced left or right depending on the skew direction, and recording cannot be performed at a predetermined position of the lens sheet L1. However, since the lens sheet L1 is conveyed while being guided by the guide unit 11, the lens sheet L1 is conveyed while maintaining a constant skew state. That is, the distance that the lens sheet L1 is conveyed is proportional to the amount of displacement of the lens sheet L1 leftward or rightward. Therefore, the inclination angle between the guide direction of the guide portion 11 and the predetermined conveyance direction is measured in advance, and the recording image data for recording is corrected according to the inclination angle, whereby the lens sheet L1 is inclined. Even if the sheet is conveyed in a line, recording can be performed at a predetermined position of the lens sheet L1.

  FIG. 3 is a diagram showing the recorded contents of the inspection image. The measurement of the inclination angle can be performed as follows. As shown in the figure, the recording apparatus 200 records an inspection image CM composed of a plurality of lines Ln, which are inspection images, on the lens sheet L1. In the image data, these lines Ln have a central line LA in the line Ln along the predetermined transport direction, and the lines Ln on the left and right of the line LA are centered on the line LA. Assume that the slopes are accumulated in the same direction in different directions in order.

  For example, the line Ln on the right side of the line LA is set so that the inclination angle is increased in order of 0.01 degrees clockwise in the conveyance direction, and the line Ln on the left side of the line LA is directed in the conveyance direction. Thus, the inclination angle is set to increase in order of 0.01 degrees in a counterclockwise direction. Based on such inspection image data, the inspection image CM is recorded on the lens sheet L1 that is conveyed while being guided by the guide unit 11.

  FIG. 4 is a diagram illustrating an image when the inspection image is viewed from the lenticular lens side. When the inspection image CM recorded on the lens sheet L1 is viewed from the lenticular lens 6 side, it is recorded along the generatrix (ridgeline) of the lens element 18 of the lenticular lens 6 in the line Ln as shown in the figure. The existing line LB can be visually recognized as one continuous line. On the other hand, since the line Ln that is not recorded along the generatrix (ridgeline) of the lens element 13 is recorded across the plurality of lens elements 18, for example, any one of the left and right sides discontinuously like the line LC or the like. The line is divided in the direction.

  Therefore, in the line Ln, the inclination angle of the line Ln corresponding to the line LB that can be seen by one line through the lenticular lens 6 is the inclination angle between the guide direction of the guide portion 11 and the predetermined conveyance direction. Can be measured as Then, corrected image data is generated by rotating the recording image data based on the measured inclination angle. By recording an image on the lens sheet L1 based on the corrected image data, the image can be recorded at a predetermined position even when the lens sheet L1 is conveyed obliquely.

  Note that the measurement of the inclination angle of the guide portion 11 in the guide direction was performed using one type of inspection image in which lines were formed at an inclination angle of 0.01 degrees. The inclination angle of the guide portion 11 in the guide direction may be measured using two different types of inspection images. For example, a first inspection image in which lines are formed at an inclination angle of 0.05 degrees is recorded on the lens sheet L1. When this inspection image is viewed through the lenticular lens 6, the length of one line is the longest. Identify long lines. Next, a second inspection image is formed on another lens sheet L1 in which lines are formed at an inclination angle of 0.01 degrees to the left and right with the inclination angle of the line as the center. Then, when the second inspection image is viewed through the lenticular lens 6, the line having the longest length of one line is specified. The inclination angle of this line can be measured as the inclination angle between the guide direction of the guide portion 11 and a predetermined transport direction.

  Thus, by measuring the inclination angle of the guide portion 11 in the guide direction using two types of inspection images, it is possible to widen the range of inclination angles that can be measured and perform high-accuracy measurement. That is, in the case of only an inspection image in which lines are formed at an inclination angle of 0.01 degrees, the inclination angle is measured only up to the number of lines of 0.01 degrees on both sides of the central line. I can't. However, it is possible to measure a wide range of tilt angles by using an image for inspection in which lines are formed at an inclination angle of 0.05 degrees, and then the lines are inclined at an inclination angle of 0.01 degrees. By using the formed inspection image, it is possible to measure the tilt angle with high accuracy. By increasing the types of inspection images, it is possible to measure the transport inclination angle with a wider range and higher accuracy.
