Abstract: The present invention provides a marker that allows a viewing direction to be determined from a detected image. A marker (100) according to the present invention includes: a lens main body (110) including a plurality of lens units (121) and a plurality of non-lens units (122). The plurality of lens units (121) and the plurality of non-lens units (122) are arranged alternately in a planar direction. Each of the lens units (121) includes, on one surface side of the lens main body (110), a light-condensing convex-shaped lens portion (121a) provided along an arrangement direction in which the lens units (121) and the non-lens units (122) are arranged. Each of the non-lens units (122) includes, on the one surface side of the lens main body (110), a non-light-condensing non-lens portion (122a). The lens main body (110) includes, on the other surface (140) side of the lens main body (110), a plurality of detectable portions (141) that can be detected from the one surface side.

Abstract: The present invention provides a marker that allows a viewing direction to be determined from a detected image. A marker (100) according to the present invention includes a lens main body (110) including a plurality of lens units (111). The plurality of lens units (111) are arranged successively in a planar direction. Each of the lens units (111) includes, on one surface side of the lens main body, a light-condensing portion (121) and a non-light-condensing portion (122) that are provided along an arrangement direction in which the lens units (111) are arranged successively. The lens main body (110) includes, on the other surface (140) side of the lens main body (110), a plurality of detectable portions (141) that can be detected from the one surface side. A pitch of the plurality of lens units (111) is different from a pitch of the plurality of detectable portions (141).

Abstract: The marker according to the present invention comprises: a first surface which includes a plurality of convex surfaces; and a second surface. The second surface includes a plurality of first areas and a plurality of second areas, wherein the interval between the centers of the plurality of first areas is greater than the interval between the apexes of the plurality of convex surfaces. The plurality of first areas are arranged farther from the convex surfaces than a focal position of the plurality of convex surfaces. When external parallel light is made incident on the convex surfaces in an upper-lower direction, the width with respect to the first direction of a light bundle formed by the convex surfaces at a height at which the first areas are arranged is not more than the width with respect to the first direction of the first areas.

Abstract: A marker (10) includes a lenticular lens (11) formed from a translucent material to have a plurality of convex portions (13) positioned to line up in, for example, at least one direction. The optical axes (OA1) of the convex portions (13) all intersect with an optical reference point (OP) on the product optical axis (PA). The optical axes (OA1) of the convex portions (13) are all orthogonal with and pass through the center of the bottom surfaces of grooves (14). Colored portions (15) are accommodated in the grooves (14).

Abstract: A composite (100) comprises: an integrally molded article of two or more function parts (111) made of a cured material of a liquid resin composition and two or more connection parts (112); and a retention part (120) made of a resin composition different from the liquid resin composition and having two or more through-holes (121) or concave parts. The function parts (111) are respectively arranged inside the through-holes (121) or the concave parts of the retention part (120). The connection parts (112) are joined to a surface of the retention part (120).

Abstract: A communication module of the present invention is a communication module including a transmission/reception part and an electromagnetic flux controlling member. The electromagnetic flux controlling member includes a first surface and a second surface. The first surface of the electromagnetic flux controlling member includes a first region including an incidence portion of near-axis light to be converged at a first focal position, the near-axis light being located closest to a central axis of the electromagnetic flux controlling member, and a second region disposed in a region surrounding the first region and including an incidence portion of light to be converged at a second focal position when parallel light is entered from the first surface and emitted from the second surface. The second focal position is located at a position farther from the electromagnetic flux controlling member than the first focal position.

Abstract: This marker has: an optically transparent convex plastic lens section having a first surface that includes convex surface sections and flat surface sections, and a second surface that includes first regions and second regions other than the first regions, the second surface being disposed in a position on the reverse side to the first surface; a section to be detected that is formed in the first regions and/or the second regions; and a positioning section formed in those regions of the second surface that correspond to the flat surface sections, the positioning section indicating positions in the first regions that correspond to the convex surface sections. The first regions are concave sections or convex sections disposed in those regions of the second surface that correspond to the convex surface sections.

Abstract: A marker (10) includes a plurality of convex surface portions (13) which are formed using a translucent material and are arranged side by side in the X-direction. Each convex surface portion (13) is inclined in one direction in the X-direction. Optical axes (OA1) of each of the convex surface portions (13) intersect at an optical reference point (OP) on a product optical axis (PA), and each also intersect a bottom surface of a groove (15). Each groove (15) is arranged in such a way that the distance thereof from a central axis (CA) of each convex surface portion (13) increases with increased distance from the product optical axis (PA) in the X-direction. A colored portion (16) is accommodated in each groove (15).

Abstract: This marker comprises a plurality of convex-surface section disposed along the X-axis direction and a plurality of detection sections disposed so as to face the convex-surface sections. Each of the detection sections is located, in the protruding direction of the convex-surface sections, closer to the convex-surface section side than a focal point on an image surface of the convex-surface section of the first optical unit in the X direction and is located on a single plane located further on the opposite side from the protruding direction than the edge of the image surface. The image surface extends from the first optical unit to the nth optical unit in the X direction, where n is at least 2.
