A mirror unit includes a concave mirror having a mirror surface reflecting light, and a holder holding the concave mirror. The concave mirror includes first to third positioning protruding portions. The holder includes: a first holder-side positioning portion defining, through contact with the first positioning protruding portion, the position of the concave mirror with respect to the holder at least in the X direction of XY-plane coordinates along the mirror surface; a second holder-side positioning portion defining, through contact with the second positioning protruding portion, the position of the concave mirror with respect to the holder at least in the Y direction of the XY-plane coordinates; and a third holder-side positioning portion defining, through contact with the third positioning protruding portion, the position of the concave mirror with respect to the holder at least in the Z direction orthogonal to the XY lane.

Mirror unit and display device

A head-up display includes: a display projecting light; a reflection part reflecting the light; a supported part disposed on the end of the reflection part and including a cylindrical shaft; a support, through which the shaft passes, rotatably supporting the supported part; and an elastic member which has a U-shape cross-section and in which a hole is formed in one end section and a spherical-surface protrusion protruding towards the hole is formed in the other end section that passes through the center axis of the hole. With the supported part supported by the support, the distal end of the shaft passes through the hole, the distal end-side inner circumferential edge of the shaft abuts the protrusion, and the inner surface of the one end section and that of the other end section of the elastic member cause the supported part and the support part to press against each other.

Head-up display device

This head-up display device according to an embodiment of the present invention is mounted on an instrument panel of a vehicle. A display means that emits display light is contained in a chassis having a light transmissive cover having a curved surface, and the display light emitted by the display means is output from the light transmissive cover. The curved surface of the light transmissive cover is curved so that the side on the front side of the vehicle is lower than the side on the back side of the vehicle, and that the curved surface is inclined toward the left-right direction of the vehicle so that a corner of the curved surface is lowest.

Provided is a vehicular heads-up display device with which it is possible to avoid burn-in of an internal component upon a reflecting member by exterior light, improving display quality. A vehicular heads-up display device, comprising a case body () whereon an aperture part () is disposed and a light-emitting body () that is housed within the case body () reflects emitted light L that is emitted by the light-emitting body () externally to the case body () via the aperture part () and reflects said emitted light L from the windshield (), causing the driver () to have sight of the virtual image V that is obtained by said reflection. The vehicular heads-up display device further comprises a semi-transmissible cover () installed in the aperture part (), and a dispersal means () is disposed between the light emitting body () and the cover (), for dispersing exterior light that enters the case body () via the cover ().

Vehicular heads-up display device

Provided is a head-up display (HUD) device capable of effectively preventing damage to a liquid-crystal display device due to entry of exterior light. A HUD device has a liquid-crystal panel, and is provided with a liquid-crystal display device for realizing a transparent display using light from a backlight, a control means for controlling the liquid-crystal display device, and an optical system for reflecting the display light outputted by the liquid-crystal display device onto a windshield. A flat mirror constituting the optical system allows infrared rays of incident light to pass behind the mirror and reflects the visible light. The HUD device is provided with an infrared-ray sensor positioned behind the flat mirror, and the control means reduces the brightness of the light of the backlight or extinguishes the backlight when the strength detected by the infrared-ray sensor exceeds a predetermined threshold.

A combiner storage device is equipped with: a holder for holding a combiner; a first connection section that can rotate about a first fixed shaft, said first fixed shaft being positioned at one end of the first connection section, and the other end of the first connection section being connected to the holder; and a second connection section that can rotate about a second fixed shaft, said second fixed shaft being positioned at one end of the second connection section, and the other end of the second connection section being connected to the holder. The combiner can be moved from a projected state to a stored state by means of a four-link mechanism.
