Patent number: 9878359Abstract: [Problem] To provide a bending device with a novel structure capable of efficiently bending a metallic plate without scratching or denting the plate. [Solution] A device (10) for bending a metallic plate (W) mounted on a pair of movable plates (35, 35) by applying pressing force to the metallic plate by an upper die (20) along a central axis (X), wherein against the biasing force of a coil spring (45), the movable plates move with the extension of the metallic plate during bending, and therefore the metallic plate is not scratched. The upper surface of each of the movable plates is a perfect flat surface, and therefore does not dent the metallic plate being subjected to the pressing force by the upper die.Type: GrantFiled: March 3, 2015Date of Patent: January 30, 2018Assignee: TOKYO SEIMITSU HATSUJO CO., LTD.Inventor: Takaaki Maeda

Publication number: 20170259316Abstract: A metal plate bending device, including a lower die having a main body including a pair of arc-shaped cross-sectional recesses formed on an upper surface in a symmetric design with respect to a center line, and swingable members swingably received in said recesses respectively. An upper die is arranged above said lower die movably along said center line relative to said lower die, wherein said upper die is moved toward a metal plate mounted on said lower die causing a press-push force to said metal plate to, causing said swingable members to swing and bend said metal plate along said center line. A movable plate is slideably in planar contact with a flat upper surface of the swingable members and is a flat supporting surface. During bending, said movable plate is slideable with respect to said swingable member, and is moved together with said metal plate.Type: ApplicationFiled: May 25, 2017Publication date: September 14, 2017Inventor: Takaaki Maeda

Patent number: 8273004Abstract: A paper folding mechanism includes: first and second folding rollers (51, 52); first and second conveyance rollers (61, 62); a protrusion member (71); and a control part. Both the rollers (51, 52) are provided so that a paper is sandwiched therebetween with its fold line located in front, and is allowed to pass therethrough in a first direction. The first folding roller (51) and the first conveyance roller (61) are provided so that the paper is sandwiched therebetween and conveyed in a second direction orthogonal to the first direction. The second folding roller (52) and the second conveyance roller (62) are provided so that the paper is sandwiched therebetween and conveyed in any one of the second direction and the direction opposite thereto. The protrusion member (71) is provided so that the fold line of the paper conveyed by both the rollers (61, 62) is protruded in the first direction and fed between both the rollers (51, 52).Type: GrantFiled: February 26, 2009Date of Patent: September 25, 2012Assignee: Duplo Seiko CorporationInventors: Ryuichi Oota, Hideki Oiwa, Masasuke Funase, Takaaki Maeda

Patent number: 8270803Abstract: A reproducing operation of still image content and a reproducing operation of moving image content are carried out by similar inputs by a user. A video recording and reproducing processing unit reproduces video content, and a Web content processing unit automatically selects instructions, such as information for instructing another Web page to be displayed next, from data of a reproduced Web page, and reproduces the another Web page. As a result, a plurality of Web pages are continuously reproduced and output at predetermined time intervals. A main control unit controls the reproduction of video content by the video recording and reproducing processing unit and the continuous reproduction of Web content by the Web content processing unit based on signals input by operations to a single group of operating keys as interpreted by an input conversion table.Type: GrantFiled: December 23, 2004Date of Patent: September 18, 2012Assignee: Sony CorporationInventors: Hidetoshi Ichioka, Takaaki Maeda, Mutsumi Kogawa, Shinichi Wakai, Hitoshi Kimura
