Patent number: 11117468Abstract: A display device for a vehicle includes: a dial plate having an indicator portion corresponding to vehicle information on a viewing side; an image display panel disposed on a back side of the dial plate opposite to the viewing side to luminescently display an image; and a light transmissive display plate that includes a reflective portion disposed on the viewing side of the dial plate to reflect a light from a light source to the viewing side. A region of the dial plate, which faces the image display panel, is set to have a light transmission property to transmit the image of the image display panel through the region of the dial plate.Type: GrantFiled: April 26, 2019Date of Patent: September 14, 2021Assignee: DENSO CORPORATIONInventors: Katsumi Fujita, Kouzou Ono, Shota Nojiri, Takuo Yamamoto, Shizuo Nagata, Yuuki Uekubo, Masashi Nakamura, Kouta Fukutomi, Tadaaki Ishimaru

Patent number: 9714750Abstract: A vehicular display apparatus includes: first illumination portions that illuminate first display areas from behind by luminescence of a plurality of first light sources; first cover portions that are placed behind the first display areas and internally expose the first light sources; a second illumination portion that illuminates a second display area from behind by luminescence of a plurality of second light sources; and a second cover portion that is placed behind the second display area and has an interior partitioned from the interiors of the adjoining first cover portions while internally exposing the second light sources. The first cover portions externally form an air passage for an air flow. The second cover portion has an air hole opened to communicate the interior of the second cover portion with the air passage external to the first cover portion.Type: GrantFiled: May 16, 2013Date of Patent: July 25, 2017Assignee: DENSO CORPORATIONInventors: Tadaaki Ishimaru, Takayuki Hiromitsu

Patent number: 6120158Abstract: An indicator for use in a vehicle instrument panel has a light conductive pointer illuminated by a light emitting diode or LED. In order to provide an increased illuminating surface of the pointer, a slit is formed on a cap to extend from the outer periphery of the cap to a portion above a center of rotation of the pointer driven by a driving shaft. A fixture is connected to the driving shaft and holds a light receiving portion of the pointer at the portion above the center of rotation and the LED in the optical alignment with the pointer at a portion off an axis of the center of rotation. A balancing weight is disposed at a portion opposite the LED with respect to the driving shaft in order to keep balance of the indicator.Type: GrantFiled: August 3, 1998Date of Patent: September 19, 2000Assignee: Nippondenso CorporationInventors: Tadaaki Ishimaru, Teruaki Araki, Tsutomu Yoshikawa
