  Moreover, it is preferable that the manufacturing apparatus of such a three-dimensional still image printed matter adhere | attaches by pressing or thermocompression bonding a still image sheet and a film with a 3D roller and a feed roller.

  If the manufacturing apparatus of the three-dimensional still image printed matter according to the present invention is configured as described above, the three-dimensional still image printed matter can be easily manufactured.

It is explanatory drawing for demonstrating a three-dimensional still image printing part, Comprising: (a) shows a side view, (b) shows a top view. It is explanatory drawing when the manufacturing apparatus of a stereo still image printed matter is seen from upper direction. It is explanatory drawing when the manufacturing apparatus of a stereo still image printed matter is seen from the side.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, a three-dimensional still image printed matter manufactured by a three-dimensional still image printed manufacturing apparatus (hereinafter simply referred to as “manufacturing apparatus”) according to the present embodiment will be described with reference to FIG. The three-dimensional still image printed matter 50 is a film formed by continuously arranging a still image sheet 30 on which a stereoscopic still image pattern is printed and a kamaboko type (semi-columnar) lens shape (lenticular lens 40a). 40. Here, on the still image sheet 30, as the still image pattern for forming a three-dimensional still image, the same subject is photographed, the image for the left eye when viewed with the left eye and the image for the right eye when viewed with the right eye Each of the images is divided into strip images having a predetermined width, and these strip images are alternately arranged in an interlaced manner as the left eye line 30L and the right eye line 30R and printed. The individual lenticular lenses 40a are attached to the pair of left-eye lines 30L and right-eye lines 30R while being aligned with each other. As described above, since the lenticular lens 40a has a semi-cylindrical shape along the left and right eye lines 30L and 30R, when the three-dimensional still image printed matter 50 is viewed with the longitudinal direction of the lenticular lens 40a up and down. The left eye can observe the left eye line 30L via the lenticular lens 40a, and the right eye can observe the right eye line 30R via the lenticular lens 40a. Can be seen.

  As shown in FIGS. 2 and 3, the manufacturing apparatus 10 that manufactures such a three-dimensional still image printed matter 50 has a transparent film on the still image sheet 30 on which a stereoscopic image (still image pattern) is printed. 40 is adhered, and a lens shape (lenticular lens 40a) is formed on the film 40. The manufacturing apparatus 10 includes a 3D roller 11, a feed roller 12, a motor 13 that rotationally drives the 3D roller 11, and an encoder 14 that is attached to the rotation shaft of the motor 13 and detects the position of the 3D roller 11 in the rotation direction. The position detector 15 for detecting the relative positions of the left and right eye lines (still image patterns) 30L and 30R printed on the still image sheet 30 with respect to the 3D roller 11, and the detection values from the encoder 14 and the position detector 15. And a control device 16 for controlling the operation of the motor 14 based on the control device 16.

  The 3D roller 11 and the feed roller 12 are formed in a cylindrical shape, and their cylindrical axes are arranged in parallel vertically, and their circumferential surfaces are arranged close to each other. When the still image sheet 30 and the film 40 are overlapped and inserted into the contact portion between the 3D roller 11 and the feed roller 12 and the 3D roller 11 is rotated forward about the cylindrical axis by the motor 13 (in FIG. 3). When rotated counterclockwise), the still image sheet 30 and the film 40 are sandwiched by these rollers 11 and 12 and can be sent out in the right direction in FIGS. Note that the feed roller 12 that sandwiches the still image sheet 30 and the film 40 together with the 3D roller 11 rotates clockwise in accordance with the rotation of the 3D roller 11 in FIG. 3. Here, on the circumferential surface of the 3D roller 11, concave grooves 11a (concave portions) extending in the rotation axis direction are continuously formed in the circumferential direction. Therefore, when the still image sheet 30 and the film 40 are sent out, the film 40 is pressure-bonded (adhered) to the still image sheet 30, and the surface of the film 40 has a shape of the groove 11 a up and down. A convex portion extending in the direction, that is, a lenticular lens 40a is formed, and the three-dimensional still image printed matter 50 is manufactured.

  Further, in the manufacturing apparatus 10, the position detector 15, the encoder 14, and the control device 16 described above are used as synchronization means for synchronizing the still image sheet 30 and the rotation position of the 3D roller 11. Specifically, the left and right synchronization mark 30a for detecting the positions of the left and right eye lines 30L and 30R is printed on the still image sheet 30 together with the stereoscopic image. The left-right synchronization mark 30a is, for example, the boundary between the left-eye line 30L and the right-eye line 30R (the position where the center of the lenticular lens 40a is formed), the right-eye line 30R, and the left-eye line 30L. Is printed so as to be able to detect the boundary portion (the position at which the left and right end portions of the lenticular lens 40a are formed). In this manufacturing apparatus 10, since the relative position of the position detector 15 with respect to the 3D and the feed rollers 11 and 12 is known, the control device 16 adds the left and right synchronization mark 30 a detected by the position detector 15 to the 3D roller 11 by the motor 13. That is, the positions of the left and right eye lines 30L and 30R on the still image sheet 30 when 3D and the feed rollers 11 and 12 are clamped from the position of the left and right synchronization mark 30a are calculated from the encoder 14. The lenticular lens 40a formed when the groove 11a is pressed against the sheet 50 is controlled so as to be aligned with the left and right eye lines 30L and 30R according to the position of the 3D roller 11 that is output.

  If the manufacturing apparatus 10 of the three-dimensional still image printed matter 50 is configured as described above, the lenticular lens 40a is formed when the film 40 is adhered on the still image sheet 30. Therefore, the alignment accuracy of the lenticular lens 40a can be improved with respect to the left and right eye lines 30L and 30R. Further, since the lenticular lens 40a can be formed simultaneously with the adhesion between the still image sheet 30 and the film 40, the manufacturing process can be simplified and the manufacturing efficiency can be improved.

  Note that a printing device 20 that prints a stereoscopic image and a left-right synchronization mark on the still image sheet 30 is arranged on the side of the manufacturing apparatus 10, and printing on the still image sheet 30 by the printing device 20 is performed. If the manufacturing apparatus 20 is configured to continuously manufacture the three-dimensional still image printed matter 50, the manufacturing efficiency can be further improved. With such a configuration, software for performing stereoscopic image printing and printing of the left and right synchronization mark 30a is added to the printing apparatus 20, and the manufacturing apparatus 10 is further installed at a low price. And the system which manufactures the stereo still image printed matter 50 easily can be provided.

  Further, since the alignment between the left and right eye lines 30L and 30R and the groove 11a may be performed when the still image sheet 30 and the film 40 are inserted into the 3D and the feed rollers 11 and 12, the left and right synchronization mark 30a is stationary. The image sheet 30 may be formed only at the front end portion (the front end portion on the side inserted into the 3D and the feed rollers 11 and 12). Further, the printing position of the left / right synchronization mark 30a is not limited to the lower end portion on the front side as shown in FIG. 2, and can be any position that can be detected by the position detector 15 regardless of the front or back side of the still image sheet 30. It may be formed anywhere.

  Further, by providing the position detector 17 also on the 3D and the three-dimensional still image print 50 fed from the feed rollers 11 and 12, the lenticular lens 40a formed on the film 40 and the left and right eye lines 30L and 30R are provided. Whether the position is aligned can be detected and output to the control device 16. When the position detector 17 detects that the positions of the lenticular lens 40a and the left and right eye lines 30L and 30R are displaced, the control device 40 can perform alignment again.

  In the above description, the case where the kamaboko type lenticular lens 40a extending in the direction orthogonal to the conveying direction is formed on the film 40 is described. However, as the lens shape formed on the film 40, a hemispherical lens is formed. You may comprise so that it may form. In this case, by using a hemispherical lens, the hemisphere can be stereoscopically viewed not only when the line of sight of the three-dimensional still image print 50 is shifted in the horizontal direction but also when it is shifted in the vertical direction. A still image pattern may be printed on a pattern matched to a lens. The hemispherical lens may be formed in a hemispherical honeycomb shape (hexagonal shape).

  Further, the film 40 may be bonded to the still image sheet 30 not only by pressure bonding but also by heat pressure bonding. Further, when a stepping motor is used as the motor 13, it is possible to obtain the position of the rotating shaft in the rotational direction, and therefore the encoder 14 as a synchronizing means is unnecessary. Further, when these boundaries can be discriminated from images (still image patterns) printed as the left and right eye lines 30L and 30R, the position detector 15 does not need to print the left and right synchronization marks 30a. The position of the still image sheet 30 can be detected.
