Patent number: 9970597Abstract: A flexible printed circuit board on which a first electronic component and a second electronic component are to be mounted adjacent to each other has a first land for soldering a terminal of the first electronic component on a side adjacent to the second electronic component, and a second land for soldering a terminal of the second electronic component on a side adjacent to the first electronic component. The first land and the second land are connected by a wire extending outside of an inter-land region that is an approximately belt-shaped region formed by connecting end portions in a width direction or end portions in a thickness direction of the first land and the second land in a straight line.Type: GrantFiled: January 22, 2015Date of Patent: May 15, 2018Assignee: OMRON CORPORATIONInventor: Kensuke Nambu

Patent number: 9599768Abstract: A surface light source includes a light source facing an end face of a lightguide plate, a rectangular-shaped frame surrounding an outer peripheral surface of the lightguide plate, and a reflecting sheet disposed in on a lower surface of the frame. The frame includes an inside frame portion made of a white resin, and an outside frame portion made of a black resin, with the interface between the inside and outside frame portions being inclined with respect to the inside surface of the inside frame portion. The inside frame portion and the outside frame portion are integrally molded by a two-color molding method.Type: GrantFiled: August 19, 2014Date of Patent: March 21, 2017Assignee: OMRON CorporationInventors: Kenji Ozawa, Kensuke Nambu, Yuichi Hiraki

Patent number: 9513430Abstract: A planar light source apparatus has a light guide plate, a light source arranged on a side face of the light guide plate, a mounting substrate on which the light source is mounted, and a frame body that holds the light guide plate. The frame body has a plurality of projection portions on an inner side of the frame body. The light source is arranged between the projection portions. The frame body, the mounting substrate, and the light guide plate are fixed via a fixing member. The light source has a pair of electrode terminals. The mounting substrate has a land portion on which the electrode terminals are mounted. Connection portions are provided by which the electrode terminals and the land portion are electrically connected. The projection portions have a thickness defined by a surface on the mounting substrate side and an opposite surface relative thereto.Type: GrantFiled: January 20, 2015Date of Patent: December 6, 2016Assignee: OMRON CorporationInventors: Kensuke Nambu, Koichi Takemura

Patent number: 8864358Abstract: In a surface light source device frame, an amount of light that leaks from an outer peripheral surface of the frame can be decreased while a decrease in luminance is suppressed in an emission surface. The frame includes a rectangular frame main body made of a black resin and an auxiliary member made of a white resin. In inner peripheral surfaces of both lateral sides of the frame main body, fitting portions are provided in an end portion on a side farther away from the light source in the frame main body in order to fit the leg portions. The auxiliary member is attached to the inner peripheral surface on the side farther away from the light source in the frame main body while the leg portions are fitted in the fitting portions.Type: GrantFiled: August 25, 2011Date of Patent: October 21, 2014Assignee: OMRON CorporationInventors: Kensuke Nambu, Kenji Ozawa, Yuichi Hiraki

Publication number: 20140307469Abstract: Light that leaks from an outer peripheral surface of a lightguide plate can be reflected and returned to the lightguide plate by a frame, and light that is transmitted through the frame to leak out can be reduced. A reflecting sheet is disposed in a lower surface of the frame, and the lightguide plate and the light source are accommodated in the frame. The frame is formed such that an outer peripheral surface of a rectangular-frame-shaped inside frame portion made of a white resin is covered with a rectangular-frame-shaped outside frame portion made of a black resin. The inside frame portion and the outside frame portion are integrally molded by a two-color molding method.Type: ApplicationFiled: August 25, 2011Publication date: October 16, 2014Applicant: OMRON CORPORATIONInventors: Kenji Ozawa, Kensuke Nambu, Yuichi Hiraki
