  At least the following matters will become clear from the description of the present specification and the accompanying drawings.

  In a recording apparatus that conveys a recording medium having a lenticular lens and performs recording on the recording medium, a guide roller that rotates while contacting the recording medium when the recording medium is conveyed in a conveying direction, A recording apparatus including a guide roller having a convex portion for contacting the lenticular lens becomes apparent. According to such a recording apparatus, the recording position accuracy can be increased with a simple configuration.

  When the guide roller is viewed from a direction perpendicular to the conveyance direction and perpendicular to the rotation axis of the guide roller, the convex portion is formed on the circumferential surface of the guide roller along the conveyance direction. It is desirable that As a result, the recording medium can be transported with high accuracy while keeping the generatrix direction of the lens in the transport direction.

  It is desirable that the convex portion is formed on the circumferential surface of the guide roller along the direction of the rotation axis of the guide roller. Thereby, the recording medium can be conveyed with high accuracy while the generatrix direction of the lens is parallel to the rotation axis of the guide roller.

  When recording the recording medium having the lenticular lens, the recording medium is conveyed so as to pass through the portion where the convex portion is formed, and when recording the recording medium not having the lenticular lens, the convex portion is formed. It is desirable to convey the recording medium so as to pass through a portion that is not formed. Thereby, it is not necessary to make the mark of a convex part.

  The guide roller has a first convex portion for contacting a lenticular lens having a first lens pitch and a second convex portion for contacting a lenticular lens having a second lens pitch different from the first lens pitch. It is desirable. Thereby, recording media having different lens pitches can be conveyed.

  Preferably, the first convex portion has a shape higher than that of the second convex portion, and the second convex portions are arranged at an interval that is an integral multiple of the first lens pitch. Thereby, when the recording medium having the first lens pitch is conveyed, the crest of the lens does not need to contact the second convex portion.

  It is desirable that the first convex portion is disposed outside the second convex portion. Accordingly, when the recording medium having the second lens pitch is conveyed, the first convex portion can be prevented from contacting the recording medium.

  It is desirable that the transport position of the recording medium in the direction of the rotation axis of the guide roller differs according to the lens pitch of the lenticular lens of the recording medium. Alternatively, it is desirable that the position of the guide roller in the direction of the rotation axis of the guide roller differs according to the lens pitch of the lenticular lens of the recording medium. Thereby, recording media having different lens pitches can be conveyed.

  A convex portion formed on a guide roller is brought into contact with the lenticular lens of a recording medium having a lenticular lens, and the guide roller is rotated while the convex portion is brought into contact with the lenticular lens, thereby the recording medium. Is conveyed in the conveying direction. The conveying method is characterized. According to such a recording method, the recording position accuracy can be increased with a simple configuration.

=== Lens sheet ===
First, a lens sheet that is a recording medium having a lenticular lens will be described.
FIG. 1A is an enlarged cross-sectional view of a lens sheet. FIG. 1B is a view of the lens sheet as viewed from the lenticular lens side. FIG. 1C is an explanatory diagram of another lens sheet.

The lens sheet L includes a lenticular lens 7 and an image forming layer 8.
The lenticular lens 7 is a resin optical member (cylindrical lens array) in which a large number of cylindrical lenses 13 are arranged in the sheet surface direction. In the following description, the generatrix direction of the cylindrical lens 13 is referred to as “x direction”, and the direction in which the cylindrical lenses 13 are arranged is referred to as “y direction” (x and y are lowercase letters). Further, the most projecting portion (peak) of each cylindrical lens 13 is called a “mountain”, a concave portion between the cylindrical lenses is called a “valley”, and a continuous line of mountains is called a “ridge line”, which is parallel to the ridge line. The direction may be referred to as the “bus line direction”.

  The image forming layer 8 includes an ink transmission layer 8A and an ink absorption layer 8B. The ink transmission layer 8A is located outside the lens sheet L, and the ink absorption layer 8B is located between the ink transmission layer 8A and the lenticular lens 7. When an image is recorded by the inkjet recording method from the image forming layer 8 side of the lens sheet L, the ink passes through the ink transmission layer 8A and is absorbed by the ink absorption layer 8B, and the image can be visually recognized through the lenticular lens 7.

  The image forming layer 8 of the lens sheet L may be omitted. For example, if an ultraviolet curable ink is used, an image can be recorded directly on the back surface of the lenticular lens 7 without the ink transmission layer 8A and the ink absorption layer 8B.

  The recording apparatus of this embodiment described below conveys the lens sheet L using the shape of the lenticular lens 7. Specifically, a convex portion is formed on a guide roller (described later), and the lens sheet L is conveyed while a valley between cylindrical lenses is engaged (contacted) with the convex portion.

  As a result, each cylindrical lens 13 of the lenticular lens 7 is positioned at a predetermined position at the recording position of the recording apparatus (position where the head ejects ink to form an image). As a result, an image can be recorded with high accuracy in accordance with the lens arrangement of the lenticular lens 7.

  In FIG. 1B, the direction of the side of the lens sheet L coincides with the x direction and the y direction. However, as shown in FIG. 1C, the direction of the side of the lens sheet L may not match the x direction or the y direction depending on the type of the lens sheet L or the manufacturing accuracy of the lens sheet L. The recording apparatus of the present embodiment can accurately record an image on a lens sheet L as shown in FIG. 1C according to the lens arrangement of the lenticular lens 7.

  Also in the case as shown in FIG. 1B, the crest of the cylindrical lens 13 may be located on the side of the lens sheet L, or the trough may be located. According to the recording apparatus of the present embodiment, each cylindrical lens 13 of the lenticular lens 7 is positioned at a predetermined position regardless of whether the crest or trough of the cylindrical lens 13 is located on the side of the lens sheet L. become.

In FIG. 3, the transport direction of the recording apparatus 100 is the X direction, the main scanning direction of the head is the Y direction, and the vertical direction is the Z direction (X, Y, and Z are capital letters). As will be described later, the X direction (the conveyance direction of the recording apparatus 100) and the x direction (the generatrix direction of the lens of the lens sheet L) coincide with each other.

The computer 110 which is an external device generates an image to be recorded on the recording device 100 and transmits recording data to the recording device 100. When recording on the lens sheet L, the computer 110 generates a recording image by processing and synthesizing a plurality of images designated by the user according to the lens pitch or the like, and records the images. The recording data is transmitted to the recording apparatus 100. Note that the recording apparatus 100 may have a function of generating recording data.
The recording apparatus 100 performs recording on a medium based on the recording data received from the computer 110. When recording on the lens sheet L, an image is recorded on the back surface of the lens sheet L based on recording data generated according to the lens pitch.

  The recording apparatus 100 includes a housing 2, a paper feed table 3, a transport roller 4 and a paper discharge roller 5, a head 6, and a first guide roller 31 and a second guide roller 32. The housing 2 is an exterior body of the recording apparatus 100. The sheet feed table 3 supports the lens sheet L when the lens sheet L is supplied to the recording apparatus 100. The transport roller 4 and the paper discharge roller 5 transport the lens sheet L placed on the paper feed table 3 in the transport direction. The first guide roller 31 and the second guide roller 32 convey the lens sheet L in the conveyance direction while restricting the movement of the lens sheet L in a predetermined direction. The head 6 performs recording on the lens sheet L.

  The housing 2 is provided with a paper feed opening 9 and a paper discharge opening 10. The lens sheet L supplied from the paper feed opening 9 is transported in the transport direction by the transport roller 4 and the paper discharge roller 5, and is recorded by the head 6. To be discharged.

  The paper feed table 3 has a rectangular plate-like body as a whole. The sheet feed table 3 has a length extending from a position protruding from the sheet feed opening 9 to a position in front of the conveyance roller in the conveyance direction. Further, with respect to the Y direction (or the width direction of the lens sheet L), there is a width that can support the entire width of the lens sheet L.

  The paper feed roller 24 supplies the lens sheet L placed on the paper feed tray 3 into the recording apparatus 100. The paper feed roller 24 is rotationally driven by a paper feed motor (not shown). The lens sheet L is guided between the transport roller 4 and the first guide roller 31 by paper feeding by the paper feeding roller 24.

  A transport roller 4 and a paper discharge roller 5 are disposed before and after the head 6. A conveyance roller 4 and a paper discharge roller 5 are arranged. The transport roller 4 is a roller for transporting the lens sheet L supplied from the paper feed opening 9 to a recording position (a position where the head 6 performs recording). The paper discharge roller 5 is a roller for discharging the lens sheet L recorded at the recording position to the paper discharge opening 10. The transport roller 4 is rotationally driven by a transport motor 16, and the paper discharge roller 5 is rotationally driven by a paper discharge motor 17.

  The first guide roller 31 is provided to face the transport roller 4. When the conveyance roller 4 is rotationally driven with the lens sheet L sandwiched between the first guide roller 31 and the conveyance roller 4, the first guide roller 31 is driven to rotate and convey the lens sheet L in the conveyance direction. The configuration of the first guide roller 31 will be described later.

  The second guide roller 32 is provided to face the paper discharge roller. When the paper discharge roller 5 is rotationally driven with the lens sheet L sandwiched between the second guide roller 32 and the paper discharge roller 5, the second guide roller 32 is driven to rotate, and the lens sheet L is discharged in the transport direction. Make paper. The shape of the second guide roller 32 is the same as that of the first guide roller 31.

  The head 6 is an ink jet recording head that ejects ink, and is attached to the lower surface of the carriage 18. A platen 23 for supporting the lens sheet L is provided at a position facing the head 6. The lens sheet L conveyed to the recording position by the conveying roller 4 is supported by the platen 23 at the recording position.

  The carriage 18 is supported by a carriage guide 19 provided along the Y direction so as to be movable in the Y direction, and is attached to a timing belt 21 driven by a carriage motor 20. Therefore, when the timing belt 21 is rotationally driven by the carriage motor 20, the head 6 can reciprocate in the Y direction together with the carriage 18.

  The controller controls the conveyance of the lens sheet L in the conveyance direction by controlling the conveyance motor 16 and the paper discharge roller 17. The controller controls the movement of the head 6 by controlling the carriage motor 20. The controller controls ink ejection from the head 6. As a result, the controller can record an image at a desired position on the lens sheet L. When an image is recorded on the lens sheet L, the lens sheet L is placed on the paper feed table 3 so that the image forming layer 8 side faces the head 6 and the lenticular lens 7 side contacts the paper feed table 3. To do. As a result, the head 6 performs recording on the image forming layer 8, and a recorded material is created in which the image recorded on the image forming layer 8 can be viewed from the lenticular lens 7 side.

<Configuration of guide roller>
FIG. 4 is an enlarged cross-sectional view of a contact portion between the first guide roller and the lens sheet L. Since the lens sheet L is sandwiched between the first guide roller 31 and the transport roller 4, the transport roller 4 is originally positioned on the lens sheet L. However, the transport roller 4 is simplified for simplicity of explanation. Is omitted.

  The first guide roller 31 includes a main shaft 11 and an engaging portion 12 formed on the cylindrical surface of the main shaft 11. The cross-sectional shape of the engaging portion 12 is substantially the same cross-sectional shape as the lenticular lens 7. That is, the convex portions 14 having substantially the same cross-sectional shape as the cylindrical lens 7 are arranged at the same pitch as the lens pitch. Each convex portion 14 is formed along the circumferential direction of the main shaft 11. In the following description, the most protruding portion of the convex portion 14 of the engaging portion 12 may be referred to as “mountain”, and the concave portion between the convex portions 14 may be referred to as “valley”.

  The position of the first guide roller 31 is adjusted so that the valley line coincides with the transport direction (X direction) of the recording apparatus 100 when viewed from above, and is attached to the recording apparatus 100. Further, the convex portions of the second guide roller 32 are arranged side by side over a width wider than the width of the lens sheet L. The engaging portion 12 may be a separate member from the main shaft 11 or may be integrally formed with the main shaft 11.

  Since the cross-sectional shape of the engaging portion 12 is the same as the cross-sectional shape of the lenticular lens 7, when the lens sheet L is conveyed by the first guide roller 31 with the lenticular lens 7 side down, the cylindrical lens of the lenticular lens 7 is used. 13 and the convex portion 14 of the first guide roller 31 mesh with each other, the convex portion 14 of the first guide roller 31 is located between the peaks of the cylindrical lens 13, and the peaks of the cylindrical lens 13 are located on the first guide roller 31. It is located between the convex portion 14 and the convex portion 14. As a result, the movement of the lens sheet L in the Y direction with respect to the first guide roller 31 is limited, and the lens sheet L is positioned in the Y direction. On the other hand, since there is no restriction on the movement of the lens sheet L in the conveyance direction (the vertical direction in FIG. 4, the X direction), and the first guide roller 31 is driven to rotate along with the rotation of the conveyance roller 4, the lens sheet L Is movable along the transport direction. Thereby, the 1st guide roller 31 can guide the lens sheet L to a conveyance direction, restraining the movement to a Y direction.

  The second guide roller 32 has the same configuration as the first guide roller 31. Here, the description of the configuration of the second guide roller 32 is omitted. Similarly to the first guide roller 31, the second guide roller 32 can also guide the lens sheet L in the transport direction while restraining movement in the Y direction. Since the second guide roller 32 is provided downstream of the head 6 in the conveyance direction, the lens sheet L is restrained from moving in the Y direction even after the rear end of the lens sheet L has passed the conveyance roller 4. It is guided in the transport direction.

=== Modification of Guide Roller ===
<About arrangement>
FIG. 5A is a schematic explanatory diagram of the arrangement of the guide rollers of FIG. The aforementioned guide roller was provided at a position facing the transport roller 4. However, the arrangement of the guide rollers is not limited to this position. Hereinafter, modified examples of the arrangement of the guide rollers will be described.

  Drawing 5B is an explanatory view of arrangement of the 1st guide roller of the 1st modification. In the first modification, the first guide roller 31 is also used as the transport roller by rotationally driving the first guide roller 31 with a transport motor. A driven roller that rotates following the rotation of the first guide roller 31 is provided above the first guide roller 31. If the first guide roller 31 is rotationally driven by a motor as in the first modified example, when the upper end of the lens sheet L enters between the first guide roller 31 and the driven roller, the valley of the lens sheet L Is easily guided to the mountain of the first guide roller 31, and the sheet is less likely to be jammed.

  Drawing 5C is an explanatory view of arrangement of the 1st guide roller of the 2nd modification. In the second modification, the first guide roller 31 and the transport roller 4 are provided at different positions. A driven roller is provided to face the first guide roller 31, and another driven roller is provided to face the transport roller 4. The first guide roller 31 and its driven roller are accompanied by the conveyance of the lens sheet L while guiding the movement in the Y direction of the lens sheet L conveyed by the paper feed roller 24 and the conveyance roller 4 while restricting the movement in the Y direction. Followed rotation. Even in such a configuration, the first guide roller 31 can guide the lens sheet L in the transport direction while restraining the movement in the Y direction. However, compared with the case of FIG. 5B, the apparatus of FIG.

  Drawing 5D is an explanatory view of arrangement of the 1st guide roller of the 3rd modification. In the third modification, the first guide roller 31 is not disposed on the upstream side in the transport direction with respect to the transport roller 4 as in the second modification, but the first guide roller 31 is downstream in the transport direction with respect to the transport roller 4. Arranged on the side.

  5D, the guide roller guides the lens sheet L closer to the recording position than in the configuration of FIG. 5C, so that the lens sheet L can be accurately positioned at the recording position. On the other hand, according to the configuration of FIG. 5C, the conveyance roller that is rotationally driven by the conveyance motor 16 can be provided near the recording position, so that the apparatus can be downsized.

<About the shape of the engaging part (1)>
6A is an explanatory diagram of a cross-sectional shape of the engaging portion of the first guide roller in FIG. 3. The cross-sectional shape of the engaging portion of the first guide roller 31 described above was substantially the same as the cross-sectional shape of the lenticular lens 7.

  However, the engaging portion 12 of the first guide roller 31 is not limited to such a shape. Hereinafter, modifications of the engaging portion 12 of the first guide roller 31 will be described. In addition, when any of the following engaging portions 12 is viewed from above, a trough (or mountain) between the convex portions 14 is in the transport direction.

  FIG. 6B is an explanatory diagram of a cross-sectional shape of the engaging portion according to the first modification. The cross-sectional shape of the engaging portion 12 of the first modification is the opposite shape of the lenticular lens 7. In other words, the convex portion 14 of the engaging portion 12 of the first modification has a shape that fits the concave portion of the lenticular lens 7. For this reason, in FIG. 6A, the center of curvature of the cross section of the convex portion 14 was on the inner side (lower side) of the engaging portion 12, but the center of curvature of the cross section of the convex portion 14 of the engaging portion 12 of the first modified example is It is on the outer side (upper side) of the engaging portion 12. With such an engaging portion 12 of the first modified example, the restraint in the Y direction of the lens sheet L can be strengthened.

  FIG. 6C is an explanatory diagram of a cross-sectional shape of the engaging portion of the second modified example. The cross section of the convex portion 14 of the engaging portion 12 of the second modification is triangular. Even with such a shape, the lens sheet L can be restrained in the Y direction.

  FIG. 6D is an explanatory diagram of a cross-sectional shape of an engaging portion according to a third modification. Compared with FIGS. 6A to 6C, the engagement portion 12 of the third modification has a double spacing between the convex portions 14. Thus, even if the interval between the convex portions 14 is an integral multiple of the lens pitch p, the convex portions 14 are positioned in the valleys of the cylindrical lens 13 when the lens sheet L is guided by the first guide roller 31. The movement of the sheet L in the Y direction with respect to the first guide roller 31 is limited, and the sheet L is positioned in the Y direction.

  FIG. 6E is an explanatory diagram of a cross-sectional shape of an engaging portion according to a fourth modification. As for the engaging part 12 of a 3rd modification, the cross section of the convex part 14 is a rectangular shape. Even with such a shape, the lens sheet L can be restrained in the Y direction. However, since the engagement portion 12 of FIGS. 6A to 6D is less likely to form a gap with the lens than the engagement portion 12 of FIG. 6E, the positioning accuracy is higher.

<About the shape of the engaging part (2)>
FIG. 7A is a schematic explanatory diagram of the direction of the valley line of the engaging portion 12 when the first guide roller of FIG. 3 is viewed from above. (In practice, the line interval is the same as the lens pitch or an integer multiple thereof, but for the sake of explanation, the line interval is different from the actual one.) The convex portion 14 of the joint portion 12 is formed along the circumferential direction of the main shaft 11, and the direction of the valley line (or the direction of the convex portion 14) when viewed from above is in the transport direction (X direction). It has become.

FIG. 7B is a schematic explanatory diagram of the direction of the valley line when the engaging portion 12 of the first modification is viewed from above. In the first modification, the convex portion 14 of the engaging portion 12 is formed along the Y direction, and the valley line is in the Y direction. In the first modification, the lens sheet L is conveyed like a rack and pinion mechanism. That is, in the first modification, the shape of the first guide roller 31 is regarded as a pinion (circular gear) of a rack and pinion mechanism, and the shape of the lenticular lens of the lens sheet L is regarded as a rack of a rack and pinion mechanism. The lens sheet L is transported so that the L bus line direction (x direction in FIG. 1B) is the Y direction (main scanning direction of the head) of the recording apparatus. In addition, as already demonstrated, the 1st guide roller 31 may be rotationally driven with a motor and may be driven rotation.
According to the first guide roller 31 of the first modification as described above, the lens sheet L can be conveyed while preventing the generatrix direction of the lens sheet L from deviating from the Y direction. Further, even if the generatrix direction of the lens sheet L is inclined with respect to the Y direction, if the lens sheet L is conveyed using the guide roller of the first modification, the convex portion 14 of the engaging portion 12 becomes the lens sheet. Since it engages with the valley of L, the skew of the lens sheet L is corrected.

  FIG. 7C is a schematic explanatory diagram of the direction of the valley line when the engagement portion 12 of the second modification is viewed from above. In the engaging portion 12 of the second modification, a convex portion is spirally formed on the cylindrical surface of the guide roller. Depending on the type of the lens sheet L, there is a type in which the generatrix direction of the cylindrical lens is inclined at, for example, 45 degrees with respect to the rectangular lens sheet L. When the lens sheet L is conveyed while being inclined at 45 degrees with respect to the conveyance direction (X direction), the guide roller of the second modification may be used.

  FIG. 7D is an enlarged explanatory view of the engagement portion 12 of the third modified example when viewed from above. In the engaging portion 12 of the third modification, a plurality of protrusions 34 are formed in the circumferential direction, and the plurality of protrusions 34 formed in the circumferential direction are arranged in the Y direction at the same interval as the lens pitch p. Yes. If it is the 1st guide roller 31 which has such an engagement part 12, the lens sheet L can also be conveyed by making the generating line direction of the lens sheet L into X direction like the 1st guide roller 31 of FIG. 7A. 7B, the lens sheet L can also be conveyed with the generatrix direction of the lens sheet L in the Y direction.

<About the number of convex parts>
The first guide roller 31 described above was provided with a large number of convex portions 14 continuously in the Y direction at the same pitch as the lens pitch of the lenticular lens 7. However, the convex portion of the first guide roller 31 may not have such a shape.

FIG. 8A is an explanatory diagram of a first modification of the number of convex portions. Thus, even if the convex portion 14 is singular, if the convex portion 14 is formed along the circumferential direction of the first guide roller 31 and the convex portion is along the transport direction when viewed from above, The first guide roller 31 can transport the lens sheet L in the transport direction while restraining the lens sheet L in the Y direction.
FIG. 8B is an explanatory diagram of a second modification of the number of convex portions. Thus, the plurality of convex portions 14 may be arranged at the same interval as the lens pitch p of the lenticular lens 7.
FIG. 8C is an explanatory diagram of a third modification of the number of convex portions. As described above, the plurality of convex portions 14 may be arranged at intervals of an integral multiple of the lens pitch p of the lenticular lens 7.
FIG. 8D is an explanatory diagram of a fourth modification of the number of convex portions. When the plurality of convex portions 14 are provided on the first guide roller 31, it is not always necessary to have an equal interval, and the interval between the convex portions 14 may be the lens pitch p of the lenticular lens 7 or an integral multiple thereof.

  8A to 8D, the cross-sectional shape of the convex portion 14 is the same as the cross-sectional shape of the cylindrical lens of the lenticular lens 7, but it may be another shape as described above. Here, the description is omitted.

<Formation position of convex part (1)>
FIG. 9A is a view of the first guide roller as viewed from above. Convex portions are formed in the hatched portions in the figure. The first guide roller 31 is provided with a convex portion 14 over the entire width of the main shaft 11. However, the place where the convex portion 14 is provided does not necessarily need to cover the entire width of the main shaft 11.

FIG. 9B is an explanatory diagram of a first modification of the formation position of the protrusions. When there are a plurality of lens sheets L that can be recorded by the recording apparatus 100, it is preferable to form the convex portion 14 in accordance with the minimum recording width. For example, when recording is performed on the business card size to A4 size lens sheet L, the convex portion 14 is preferably formed in accordance with the position where the business card size lens sheet L having the minimum recording width passes. As a result, when the lens sheet L of any size is conveyed, at least a part of the lens sheet L passes through the convex portion forming position, and the skew of the lens sheet L is prevented at that time.
If the recording apparatus 100 is configured to convey the lens sheet L so that the position of the right end of the lens sheet L is the same regardless of the size of the lens sheet L, the lens sheet L protrudes to a position as shown in FIG. 9B. Part 14 is formed. If the recording apparatus 100 conveys the lens sheet L so that the center of the lens sheet L is the same regardless of the size of the lens sheet L, the hatched portion in FIG. 9B is the center. .

  FIG. 9C is an explanatory diagram of a second modification of the formation position of the protrusions. In the case of FIG. 9B, when the A4-sized lens sheet L is conveyed, a frictional force during conveyance is applied to the side where the convex portions 14 are formed, and it is difficult to convey the lens sheet L with high accuracy. Therefore, in this modified example, the convex portion 14 is formed not only on the right side in the figure but also on the left side, so that a frictional force acts on both sides of the lens sheet L when the A4 size lens sheet L is conveyed. Thus, the lens sheet L can be accurately conveyed. Further, it is preferable to form the convex portion 14 in accordance with the position of the left end when each regular size is conveyed so that the frictional force acts on both sides of the lens sheet L even when the other regular size lens sheet L is conveyed.

<Formation position of convex part (2)>
The recording apparatus 100 may record not only on the lens sheet L but also on paper. In such a recording apparatus 100, when a pressing force acts on the paper on the first guide roller 31, the shape of the convex portion 14 may remain on the paper. In particular, when the convex portion 14 is formed only on a part of the first guide roller 31 (for example, in the case of the first guide roller 31 as shown in FIGS. 8A and 9B), when a pressing force acts on the paper, A concentrated load is applied to the paper, and the shape of the convex portion 14 may remain on the paper.

Therefore, the position in the Y direction of the lens sheet L when recording on the lens sheet L and the position in the Y direction of paper when recording on the paper may be changed.
FIG. 10A is a diagram of the first guide roller viewed from the transport direction. FIG. 10B is a schematic explanatory diagram of the conveyance position of the lens sheet. FIG. 10C is a schematic explanatory diagram of the transport position of plain paper. In addition, although the lens sheet L and the shape of the convex part 14, the space | interval of the convex part 14, etc. in a figure differ from actual, this is for making description easy.
If the position in the Y direction of the lens sheet L when recording on the lens sheet L and the position in the Y direction of the paper when recording on the paper S are changed as shown in the figure, the shape of the convex portion 14 remains on the paper S. You do n’t have to. In other words, it is preferable that the convex portion 14 of the first guide roller 31 is formed at a position where the lens sheet L passes and where the paper S does not pass.

  In order to change the position in the Y direction when the lens sheet L or the paper S is transported, a transport position switching mechanism may be provided in the transport mechanism. Alternatively, when the lens sheet L or the paper S is accommodated in the paper feed tray, the paper feed tray is configured so that the accommodation position of the medium (the lens sheet L or the paper S) in the Y direction in the paper feed tray can be changed. Therefore, the transport mechanism may simply transport the medium from the paper feed tray in the transport direction.

=== Conveying multiple types of lens sheets ===
In the above description, it is assumed that the lens arrangement of the lenticular lens 7 of the lens sheet L is one type (for example, a lens pitch of 30 lpi). However, it is desirable that the number of recordable lens sheets L is large. In the following description, the first guide roller 31 used in a recording apparatus capable of recording both a 30 lpi lens sheet and a 60 lpi lens sheet will be described.

<First form>
FIG. 11A is a view of the first guide roller of the first embodiment viewed from the transport direction. FIG. 11B is a schematic explanatory diagram of a state where a 30 lpi lens sheet L is conveyed. FIG. 11C is a schematic explanatory diagram illustrating a state where the 60 lpi lens sheet L is conveyed.

  On one end side (right side in the drawing) of the first guide roller 31 in the Y direction, a first convex portion 14A that matches the shape of the 30 lpi lenticular lens 7 is provided. On the other hand, on the other end side (left side in the figure), a second convex portion 14B that matches the shape of the 60 lpi lenticular lens 7 is provided.

  The concave portion between the cylindrical lenses of the 30 lpi lenticular lens is deeper than the concave portion between the cylindrical lenses of the 60 lpi lenticular lens. For this reason, the 1st convex part 14A is a mountain higher than the 2nd convex part 14B.

  The number of first convex portions 14A on the right side in the drawing is smaller than the number of second convex portions 14B on the left side. This is because the concave portion of the 30 lpi lenticular lens is deep and the first convex portion 14A is formed high, so that when the 30 lpi lenticular lens and the first convex portion 14A are engaged, it is compared with that of 60 lpi. This is because the restraining force against the movement in the Y direction is large. Thereby, the range which forms 14 A of 1st convex parts on the 1st guide roller 31 can be narrowed. Even if the number of the second convex portions 14B increases, the interval in the Y direction is narrow, so the range in which the first convex portions 14A are formed on the first guide roller 31 is not so wide.

When the lens sheet L3 having the 30 lpi lenticular lens 7 is conveyed, the lens sheet L3 is conveyed toward the right side in the figure (FIG. 11B). Accordingly, the first convex portion 14A on the right side of the first guide roller 31 can guide the lens sheet L3 in the transport direction while restraining the movement in the Y direction. Since the lens sheet L3 is on the right side, the second convex portion 14B on the left side of the first guide roller 31 does not contact the lens sheet L3.
Further, when the lens sheet L6 having the 60 lpi lenticular lens 7 is conveyed, the lens sheet L6 is conveyed toward the left side in the drawing (FIG. 11C). Accordingly, the second convex portion 14B on the left side of the first guide roller 31 can guide the lens sheet L6 in the transport direction while restraining the movement in the Y direction. Since the lens sheet L6 is on the left side, the first convex portion 14A on the right side of the first guide roller 31 does not contact the lens sheet L6.
Thus, any lens sheet can be guided in the transport direction while restraining movement in the Y direction.

  In order to change the position in the Y direction when the lens sheet is conveyed according to the lens pitch of the lens sheet L, a conveyance position switching mechanism may be provided in the conveyance mechanism. In this case, the controller may switch the position of the lens sheet in the Y direction by controlling the conveyance position switching mechanism according to the type of the lens sheet. Alternatively, when the lens sheet L is placed on the paper feed table 3, the paper feed table is configured so that the placement position of the lens sheet L in the Y direction on the paper feed table can be changed. The lens sheet L may be simply conveyed in the conveying direction as it is from the sheet feeding table.

<Second form>
FIG. 12A is a view of the first guide roller 31 according to the second embodiment as viewed from the conveyance direction. FIG. 12B is a schematic explanatory diagram illustrating a state where the 30 lpi lens sheet L is conveyed. FIG. 12C is a schematic explanatory diagram illustrating a state where a 60 lpi lens sheet L is conveyed.

  A first convex portion 14 </ b> A that matches the shape of the 30 lpi lenticular lens 7 is provided on the outer side (right side in the drawing) of one end of the first guide roller 31 in the Y direction. As already described, the first convex portion 14A has a relatively high mountain. The interval between the first convex portions 14A is 1/30 inch in order to match the shape of the 30 lpi lenticular lens 7.

  Inside the first convex portion 14A (on the left side in the figure), a second convex portion 14B that matches the shape of the 60 lpi lenticular lens 7 is provided. As already described, the second convex portion 14B is lower than the first convex portion 14A. The interval between the second protrusions 14B is not 1/60 inch, but 1/30 inch. That is, the interval between the second convex portions 14B is wider than the lens pitch of the 60 lpi lenticular lens 7. The interval between the second convex portions 14B may be an integer multiple of 1/30 inch.

  The distance between the rightmost second convex portion 14B and the leftmost first convex portion 14A is an integer multiple of the lens pitch of the 60 lpi lenticular lens 7 and is an integral multiple of the lens pitch of the 30 lpi lenticular lens. It is the interval. Here, the interval is 1/30 inch, but in practice it may be wider.

  The number of first convex portions 14A on the right side is smaller than the number of second convex portions 14B on the left side. This is because the concave portion of the 30 lpi lenticular lens is deep and the first convex portion 14A is formed high, so that when the 30 lpi lenticular lens and the first convex portion 14A are engaged, it is compared with that of 60 lpi. This is because the restraining force against the movement in the Y direction is large.

When the lens sheet L3 having a 30 lpi lenticular lens 7 is conveyed, the lens sheet L3 is conveyed toward the right side in the drawing (FIG. 12B). Accordingly, the first convex portion 14A on the right side of the first guide roller 31 is engaged with the lenticular lens 7, and the lens sheet L3 can be guided in the transport direction while restraining movement in the Y direction.
In the second form, unlike the first form, the second convex portion 14B may contact the lens sheet L3. However, since the 2nd convex part 14B is arrange | positioned at the same space | interval as the lens pitch of the 30 lpi lenticular lens 7, the 2nd convex part 14B does not contact the mountain of the cylindrical lens of the lenticular lens 7. FIG. Further, since the concave portion of the 30 lpi lenticular lens is deep, there is no problem even if the second convex portion 14B exists at the concave portion of the 30 lpi lenticular lens. For this reason, the lens sheet L3 can be guided in the transport direction while restraining movement in the Y direction.

  When transporting the lens sheet L6 having the 60 lpi lenticular lens 7, the lens sheet L6 is transported toward the left side so that the right end of the lens sheet L6 is on the left side of the first convex portion 14A (FIG. 12C). For this reason, in a state where the first convex portion 14A on the right side of the first guide roller 31 is not in contact with the lens sheet L6, the second convex portion 14B engages with the lenticular lens 7 and moves the lens sheet L6 in the Y direction. It is possible to guide in the transport direction while restraining.

  In addition, the 2nd convex part 14B is formed in the space | interval of 1/30 inch which is an integral multiple of 1/60 inch. For this reason, all the 2nd convex parts 14B can be engaged with the recessed part of 60 lpi lenticular lens 7. FIG.

  In order to change the position in the Y direction when the lens sheet is conveyed according to the lens pitch of the lens sheet L, a conveyance position switching mechanism may be provided in the conveyance mechanism. In this case, the controller may switch the position of the lens sheet in the Y direction by controlling the conveyance position switching mechanism according to the type of the lens sheet. Alternatively, when the lens sheet L is placed on the paper feed table 3, the paper feed table is configured so that the placement position of the lens sheet L in the Y direction on the paper feed table can be changed. The lens sheet L may be simply conveyed in the conveying direction as it is from the sheet feeding table.

  According to the second embodiment, it is not necessary to largely change the conveyance position of the lens sheet in the Y direction.

<Third form>
In the third embodiment described below, the first convex portion 14A and the second convex portion 14B can be selectively used without changing the position of the lens sheet L in the Y direction.

  FIG. 13A is an explanatory diagram of the first guide roller 31 of the third embodiment. FIG. 13B is a cross-sectional view of the vicinity of the positioning mechanism. In addition, these figures are simplified for description, and do not indicate actual dimensions or the number of convex portions.

  The first guide roller 31 has a fixed shaft and a movable shaft. A first convex portion 14A and a second convex portion 14B are formed on the movable shaft. 14 A of 1st convex parts are shapes which fit the recessed part of a 30 lpi lenticular lens. As already described, the first convex portion 14A has a relatively high mountain. The interval between the first convex portions 14A is 1/30 inch in order to match the shape of the 30 lpi lenticular lens 7. The 2nd convex part 14B is a shape which fits the recessed part of a 60 lpi lenticular lens. Similar to the second embodiment, the interval between the second protrusions 14B is not 1/60 inch, but 1/30 inch. Similarly to the second embodiment, the distance between the rightmost second convex portion 14B and the leftmost first convex portion 14A is an integral multiple of the lens pitch of the 60 lpi lenticular lens 7 and 30 lpi. The interval is an integral multiple of the lens pitch of the lenticular lens. Here, the interval is 1/30 inch, but in practice it may be wider.

  The movable shaft has three holes on both sides of the convex portion. The three holes are used when a 30 lpi lens sheet is conveyed, a 60 lpi lens sheet is conveyed, and a paper is conveyed. This will be described later.

  A pin urged outward by a spring is provided at a predetermined position of the fixed shaft. The movable shaft is positioned and fixed with respect to the fixed shaft by fitting the pin into any hole of the movable shaft. If the pin of the hole of a movable shaft is pushed down, a movable shaft can change a position to a Y direction with respect to a fixed shaft. If the movable shaft is fixed with respect to the fixed shaft, the movable shaft and the fixed shaft can rotate integrally around the Y direction.

FIG. 13C is a schematic explanatory diagram illustrating a state where a 30 lpi lens sheet L is conveyed.
When the lens sheet L3 having the 30 lpi lenticular lens 7 is conveyed, the pin is fitted in the right hole of the three holes, and the movable shaft is positioned to the leftmost with respect to the fixed shaft. Accordingly, the first convex portion 14A engages with the lenticular lens of the lens sheet L3 being conveyed, and the lens sheet L3 can be guided in the conveyance direction while restraining movement in the Y direction.
In the third embodiment, as in the second embodiment, since the second convex portions 14B are arranged at the same interval as the lens pitch of the 30 lpi lenticular lens 7, the second lens 14 is located on the top of the cylindrical lens of the lenticular lens 7. The 2 convex part 14B does not contact. Further, since the concave portion of the 30 lpi lenticular lens is deep, there is no problem even if the second convex portion 14B exists at the concave portion of the 30 lpi lenticular lens. For this reason, the lens sheet L3 can be guided in the transport direction while restraining movement in the Y direction.

FIG. 13D is a schematic explanatory diagram illustrating a state where a 60 lpi lens sheet L is conveyed.
When the lens sheet L6 having the 60 lpi lenticular lens 7 is conveyed, the pin is fitted in the center hole among the three holes, and the movable shaft is positioned on the right side as compared with FIG. 13C. Accordingly, the second convex portion 14B is engaged with the lenticular lens 7 in a state where the first convex portion 14A is not in contact with the lens sheet L6, and the lens sheet L6 is guided in the transport direction while restraining movement in the Y direction. it can.
In addition, the 2nd convex part 14B is formed in the space | interval of 1/30 inch which is an integral multiple of 1/60 inch. For this reason, all the 2nd convex parts 14B can be engaged with the recessed part of 60 lpi lenticular lens 7. FIG.

FIG. 13E is a schematic explanatory diagram of how the paper is conveyed.
When transporting the paper, the pin is fitted in the leftmost hole among the three holes, and the movable shaft is positioned farthest to the right with respect to the fixed shaft. Thereby, the first convex portion 14A and the second convex portion 14B do not contact the conveyed paper. For this reason, there is no need to leave a mark on the convex portion on the paper.

  According to the third mode, as in the first mode and the second mode, it is not necessary to change the transport position in the Y direction according to the type of the recording medium.

=== Variation of pressure roller ===
In FIG. 5A, the transport roller 4 is a pressing roller for pressing the lens sheet L against the first guide roller 31. In FIG. 5B and the like, the driven roller is a pressing roller for pressing the lens sheet L against the first guide roller 31. In the following description, the rollers that press the lens sheet L against the first guide roller 31 may be collectively referred to as “pressing rollers”.

<About arrangement>
The pressing roller may be longer than the width of the lens sheet L, or may be shorter than the width of the lens sheet L.
Since the pressing roller presses the lens sheet L against the first guide roller 31 in order to prevent the lens sheet L from skewing, the pressing roller is provided to face at least the position where the convex portion 14 of the first guide roller 31 is formed. It only has to be.

  FIG. 14 is an explanatory diagram of an example of a pressing roller for the guide of FIG. 9C. As described above, when there are a plurality of positions where the convex portions 14 are formed, a pressing roller may be provided so as to face each convex portion forming position. Of course, also in the case of FIG. 9C, the length of the pressing roller may be longer than the width of the lens sheet L.

<About surface shape>
Concavities and convexities may be formed on the surface of the aforementioned pressing roller.
FIG. 15A is an explanatory diagram of a modified example in which a convex portion is provided on the surface of the pressing roller. The convex portion 44 of the pressing roller is provided at a position facing the convex portion 14 of the first guide roller 31. For this reason, the space | interval of the convex part 44 of a press roller is the same space | interval as the lens pitch p, or its integral multiple. Since the convex portion 44 of the pressing roller is in a position facing the convex portion 14 of the first guide roller 31, the peak of the lens sheet L is strongly pressed toward the valley of the first guide roller 31, and the skew is easily corrected. Become.

  FIG. 15B is an explanatory diagram of another modified example in which a convex portion is provided on the surface of the pressing roller. The convex portion 44 of the pressing roller in FIG. 15B is provided at a position facing between the convex portions 14 of the first guide roller 31. The correction of the skew of the lens sheet L is triggered by the peak of the lens sheet L entering the valley of the first guide roller 31. Therefore, the position of the convex portion 44 of the pressing roller is the direction of FIG. 15B rather than FIG. 15A. Is advantageous.

  In addition, when providing the convex part 44 in a press roller, it is good to use elastic materials, such as rubber | gum, so that the convex part 44 of a press roller may change easily.

=== Adjusting the position of the first guide roller ===
The first guide roller 31 needs to be attached to the recording apparatus 100 so that the direction of the convex portion 14 when viewed from above is adjusted along the transport direction. Here, an adjustment method when the first guide roller 31 is attached will be described.

FIG. 16 is an explanatory diagram of an inspection image.
The inspection image CM is an image having a plurality of lines Ln. The center line LA of the plurality of lines Ln is a line along the conveyance direction on the image data. The lines Ln on the left and right of the line LA of the inspection image CM are lines in which the slopes are accumulated in order by a certain angle. For example, the line Ln on the right side of the line LA is set so that the inclination angle is increased in order in 0.01 degree clockwise in the conveyance direction on the image data. Further, the line Ln on the left side of the line LA is set so that the inclination angle is sequentially increased in increments of 0.01 degrees counterclockwise in the conveyance direction on the image data.

  After the first guide roller 31 is attached to the recording apparatus 100, the recording apparatus 100 is used for inspection in order to inspect whether or not the convex portion 14 of the first guide roller 31 is along the transport direction when viewed from above. The image CM is recorded on the lens sheet L. If the recording apparatus 100 is ideally assembled, the line LA is recorded on the lens sheet L in accordance with the conveyance direction. That is, if the recording apparatus 100 is ideally assembled, the line LA should be recorded along the generatrix direction of the lens sheet L. After the recording apparatus 100 records the inspection image on the lens sheet L, the inspector inspects the inspection image from the lenticular lens 7 side.

  FIG. 17 is an explanatory diagram of an inspection image viewed from the lenticular lens side. Of the plurality of lines Ln, the line Ln recorded so as to coincide with the generatrix direction of the lenticular lens 7 can be visually recognized as one continuous line. On the other hand, the line Ln that is not recorded along the generatrix direction of the lenticular lens 7 is recorded across the plurality of cylindrical lenses 13, and thus becomes a discontinuously divided line such as a line LC. If the recording apparatus 100 is ideally assembled, the line LA should be visually recognized as one line. On the other hand, if the convex portion 14 of the first guide roller 31 when viewed from above is inclined with respect to the transport direction, the line LA is visually recognized as a divided line, and another line LB corresponding to the inclination angle. Is visually recognized as one line.

  Therefore, the inspector specifies a line that can be visually recognized, and adjusts the mounting angle of the first guide roller 31 by an amount corresponding to the line. For example, in this case, the attachment angle of the first guide roller 31 is adjusted so as to be inclined by 0.03 degrees with respect to the current attachment angle of the first guide roller 31. Accordingly, the first guide roller 31 is attached to the recording apparatus 100 so that the convex portion 14 of the first guide roller 31 when viewed from above is along the transport direction.

  In the above description, the inspector visually recognizes the inspection image recorded on the lens sheet L, but the present invention is not limited to this. For example, the scanner may read an inspection image recorded on the lens sheet L, and the mounting angle of the first guide roller 31 may be determined based on the read result.

=== Variation of Paper Feed ===
In the above-described embodiment, the lens sheet L is supplied from the back side of the recording apparatus 100. However, it is not limited to this.

  For example, in a recording apparatus provided with an ASF (auto sheet feeder), the lens sheet L may be supplied from the upper side of the recording apparatus 100. In a recording apparatus having a paper feed cassette that can be opened and closed from the front side of the recording apparatus, the lens sheet L may be supplied from the lower side of the recording apparatus.

  In any case, since the lens sheet L is conveyed while being guided by the first guide roller 31 before the head 6 performs recording on the lens sheet L, the lens sheet L can be accurately conveyed in the conveyance direction.

=== Other Embodiments ===
Although a recording apparatus using a head has been described as an embodiment, the above embodiment is for facilitating the understanding of the present invention and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
