A mirror device includes: a mirror having a rotation shaft and a reflecting surface that reflects display light; a support portion having a cylindrical shape, having a base end fixed and a tip end being a free end, and configured to rotatably support the rotation shaft; and a motor that pivots the mirror, in which the rotation shaft is inserted into the support portion while spreading the support portion outward in a radial direction, and is slidably supported by the support portion.

Mirror device

A mirror device includes: a mirror including a rotation shaft pivotably supported, a coupling shaft separated from the rotation shaft, and a reflecting surface that reflects display light; a coupling member including a first coupling portion coupled to the rotation shaft and a second coupling portion coupled to the coupling shaft, and configured to pivot integrally with the mirror; a motor that is connected to the coupling member via a gear and that pivots the coupling member; and a first spring having one end side immovably fixed and another end side coupled to the coupling member, and configured to apply force to the coupling member in one rotation direction.

A mirror device includes: a mirror including a rotation shaft; a gear unit having gear teeth and coupled to the rotation shaft; a worm that meshes with the gear teeth; a holding member that supports the worm; a motor configured to rotationally drive the rotation shaft via the worm and the gear teeth; and a stopper mechanism () that has a rotating member disposed coaxially with the worm, and restricts a rotation range of the worm, in which the stopper mechanism includes: a first contact portion that is provided on the rotating member and comes in contact with the worm to receive force in the rotation direction from the worm; and a second contact portion that is provided on the rotating member and is locked by the holding member, the stopper mechanism being configured to allow the worm to rotate relative to the holding member by more than one rotation.

A vehicle display device includes a display device, a reflecting mirror, an optical sensor configured to detect external light, and a controller configured to enable execution of a temperature lowering operation. The display device includes a light transmissive liquid crystal display unit disposed on an optical path of light emitted from a light source and a first optical member disposed between the liquid crystal display unit and the light source and configured to change an optical path of light that enters the first optical member from the light source and passes therethrough toward the liquid crystal display unit. The optical sensor is disposed on an optical path of the external light incident on the display device at a side opposite to the liquid crystal display unit across the first optical member. The first optical member includes a passage on an optical path through which the external light passes.

Vehicle display device including passage extending through optical member

A vehicle display device includes a display that emits a display image projected on a windshield provided outside as display light, two reflective mirrors that are disposed on a light path of the display light from the display to the windshield and reflect the display light, an optical sensor that detects the external light entering from an opening communicating between the outside and an internal space, and a controller configured to execute temperature decreasing operation of the display for decreasing a temperature thereof when the optical sensor detects the external light. The optical sensor is disposed at a position to which external light directed toward the display via the reflective mirror is reflected by the display to be directed.

Vehicle display device

A head-up display system includes an image-forming and projection device, a combiner, a housing, and a lid body. The lid body includes at least a first divided lid body and a second divided lid body which engage with each other at the time of covering an opening of the housing. The first divided lid body includes an optical path regulator that regulates an optical path of projection light of a display image projected from the image-forming and projection device in use of the combiner onto an inner side of the housing, and allows projection light, which is necessary for formation of the virtual image of the display image in the projection light of the display image, to pass through the optical path regulator. The second divided lid body includes a covering member that covers the optical path regulator at the time of covering the opening.

Head-up display system

A head-up display device includes: a light source that emits light; a condenser that condenses the light emitted from the light source in a first direction; an adjuster that adjusts the light emitted from the condenser; a first reflector that reflects the light emitted from the adjuster in a second direction different from the first direction; a display that includes an image display surface forming a display image and emits a display light representing the display image with the image display surface transmitting the light reflected by the first reflector; a second reflector that reflects the display light being emitted from the display and being incident from above; and a third reflector that reflects the display light incident from the second reflector to the projection member. The adjuster adjusts the light emitted from the condenser according to a size of the image display surface.

Head-up display device and backlight device

A backlight unit includes a housing having an opening in which an liquid crystal display device is disposed, a light source disposed inside the housing, and an optical member disposed inside the housing, turning a path of light from the light source toward the liquid crystal display device, and having a triangular prism portion made of a translucent material. The prism portion has one side wall serving as an entrance wall on which the light from the light source is incident, another side wall as an exit wall emitting light to the liquid crystal display device, and still another side wall as a reflecting wall reflecting the light incident on the entrance wall to the exit wall inside the prism portion.
