Patent number: 7764430Abstract: A display device for a vehicle is provided, by which a driver of the vehicle is free from a trouble of adjusting a display position of the virtual image without cost-up of the device. When the support start detecting means detects a support start timing of adjusting a reflection angle, for example, a timing of an operation of an operation switch or a start of an operation, the rotation control means controls the rotating means so that the reflecting member having a reflection angle indicated by the reflection angle data stored in the reflection angle data storing means is (a) rotated within an adjustment supporting range on a condition that the reflecting member is reflecting the display light from the display source and (b) returned to a reflection angle indicated by the reflection angle data.Type: GrantFiled: November 28, 2007Date of Patent: July 27, 2010Assignees: Yazaki Corporation, Toyota Jidosha Kabushiki KaishaInventors: Takeyoshi Watanabe, Daisuke Satsukawa, Tetsuya Sugiyama, Masahiro Takamatsu, Koji Nomura, Hitoshi Kumon

Patent number: 7619826Abstract: A display device for a vehicle is provided, by which an attaching position thereof can be altered depending upon an attachment limiting condition of the vehicle. The display device includes: a display source provided in an instrument panel of the vehicle; and a prism provided on a light path between the display source and an aperture of the instrument panel and refracting display light of an image displayed on the display source backward in the vehicle, wherein the prism is formed in a shape inclined upward in a backward direction of the vehicle, wherein (a) a virtual image of the image projected on a projection area of a windshield of the vehicle, onto which area the display image from the prism is projected and (b) a front view of the vehicle to be seen from an eye point of the vehicle through the windshield are seen in a superimposed manner.Type: GrantFiled: February 8, 2008Date of Patent: November 17, 2009Assignees: Yazaki Corporation, Toyota Jidosha Kabushiki KaishaInventors: Takeyoshi Watanabe, Go Nakamura, Tetsuya Sugiyama, Koji Nomura, Masahiro Takamatsu, Hitoshi Kumon
