Patent number: 11926492Abstract: A linear transport apparatus includes a transport cart, a first roller that rotates about a first rotation shaft extending from the transport cart along a first direction, a second roller that rotates about a second rotation shaft extending from the transport cart and forming an acute angle with the first rotation shaft, and a rail sandwiched between the first and second rollers to extend along a track on which the transport cart moves. The rail includes a first contact portion coming contact with the first roller and restricting movement of the transport cart in a second direction perpendicular to a direction in which the rail extends and the first direction, and a second contact portion that comes into contact with the second roller and is parallel to the second rotation shaft, and the rail includes a portion in which curvature of the track moves is different from another portion.Type: GrantFiled: June 17, 2021Date of Patent: March 12, 2024Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Takuma Nakamura, Shin Sakai, Masaoki Iwase, Kazuhiko Fukushima

Patent number: 10890706Abstract: An optical device has a light guide plate configured to guide light within a plane parallel to an emission surface thereof, and a plurality of optical deflectors arranged two-dimensionally within a plane parallel to the emission surface. Each of the optical deflectors deflects light propagating through the light guide plate, and causes the emission surface to output light forming an image in a space. Each of the optical deflectors is configured to spread the light incident thereon that has an intensity distribution corresponding to an image in a direction orthogonal to the light guide direction of the light guide plate in a plane parallel to the emission surface, and cause the emission surface to output the light which groups the light from the plurality of optical deflectors arranged along a direction orthogonal to the light guide direction, such that light radiating from the image is formed.Type: GrantFiled: November 9, 2017Date of Patent: January 12, 2021Assignee: Omron CorporationInventors: Masayuki Shinohara, Yasuhiro Tanoue, Norikazu Kitamura, Mitsuru Okuda, Kazuyuki Okada, Norihisa Kanzaki, Takuma Iwase

Patent number: 8345184Abstract: A light guide plate (63) includes a light introducing section (65), which is at a position facing a point light source (62), for confining light from the point light source, and a light guide plate main body (64), which has a thickness smaller than a thickness at an end of the light introducing section on the point light source side, for outputting the confined light to an outside from a light outputting surface by light outputting means (70). The light introducing section (65) has an inclined surface (67), which is inclined from a surface of the light introducing section towards a surface of the light guide plate main body (64). The inclined surface (67) has a directivity converting pattern (68) for converting a directivity expansion in a thickness direction of the light guide plate of the light entered to the light introducing section (65) to directivity characteristics tilted towards a direction parallel to a surface direction of the light guide plate.Type: GrantFiled: June 10, 2008Date of Patent: January 1, 2013Assignee: OMRON CorporationInventors: Masayuki Shinohara, Yasuhiro Tanoue, Kazuhide Hirota, Koichi Takemura, Takuma Iwase, Takako Ishikawa, Yoshihiro Ueno, Morihisa Ota, Jun Kishimoto, Gouo Kurata, Yukihiro Takahashi, Hiroyuki Miyamoto
