A combiner lifting device includes: a support unit that includes a first pin and a second pin, and supports a combiner; and two side surface portions disposed on both sides of the combiner, respectively. Each of the side surface portions includes a first groove along which the first pin slides, and a second groove along which the second pin slides. The side surface portions support the support unit in such a manner that the support unit is rotatable around the first pin when the first pin is located at an end of the first groove.

A vehicle display system includes a display device, a determiner, and a display controller. The display device is mounted on a vehicle. The determiner is configured to determine whether a person present outside the vehicle enters a blind spot of a driver of the vehicle. The display controller is configured to control, when the person enters the blind spot, the display device to display a warning to the person.

Disclosed herein is a head-up display apparatus integrated with a cluster. The head-up display apparatus integrated with the cluster may include a cluster housing unit provided in front of a driver, a cover unit mounted to a top of the cluster housing unit and having a display unit, and a combiner unit rotatably coupled to the cover unit, light generated in the cluster housing unit being irradiated onto the combiner unit to form an image.

Provided are a projection-type display device, a safe-driving support method, and a non-transitory computer readable recording medium storing a safe-driving support program capable of securing safety while providing sufficient information to a driver even in a situation where a field of vision in a traveling direction of a motor vehicle is poor. An HUD includes a light modulation unit that modulates light emitted from a light source unit; a projection unit that projects the light modulated by the light modulation unit onto a combiner; a first image information generation unit that generates first image information and outputs the first image information to the light modulation unit; a second image information generation unit that generates second image information and outputs the second image information to a display device; and a control unit that controls operations of the first image information generation unit and the second image information generation unit.

A panel opening/closing device includes: a support which supports a panel and is turnable about a first rotary shaft; a dial which is turnable about a second rotary shaft in accordance with an operation by a user; and a movable unit which undergoes horizontal movement and includes pins inserted into a groove of the dial and a groove of the support, respectively.

An information provision device and an information provision method. Each of the information provision device and information provision method includes projecting an image light to a light transmission member so as to display a for-driver information image, sensing a relative distance of an object to be detected existing around the mobile object in the direction of travel, detecting a location of a viewpoint of the driver, and changing a position at which an object image indicating the object to be detected is displayed according to a result of the detecting so as to change a perception distance of the driver influenced by a motion parallax of the object image according to the relative distance of the object to be detected in the direction of travel.

In a head-up display device, in accordance with lifting and lowering operations of a combiner, each protrusion of a combiner support moves along a guide portion, causing a cover-operation member to turn about a rotary axis in a direction in which a cover is opened or closed. The guide portion includes, from top in order: a first guide portion which engages with the protrusion in a first state (use state); a second guide portion which engages with the protrusion when the cover-operation member turns; and a third guide portion which engages with the protrusion in a second state (non-use state). The angle formed by the direction in which the first guide portion extends and the direction in which the third guide portion extends is less than the angle formed by the direction in which the first guide portion extends and the direction in which the second guide portion extends.

A combiner is fastened to a base in a mobile object with a fastening member having a planar seat surface. The combiner displays a display light image as a virtual image visible to an occupant in the mobile object when the display light image is projected from a projection unit. The combiner includes a projection main body and a fastening protrusion. The projection main body is set with a projection region and has reflection surfaces displaying a virtual image by reflecting the display light image projected onto the projection region in a shape of a curved surface. The fastening protrusion has a planar fastening surface in surface contact with the seat surface. The fastening protrusion protrudes from the projection main body and is fastened to the base with the fastening member inserted into the fastening protrusion.

Provided is a display device for a vehicle that can rapidly execute preparation completion for display of vehicle information. The display device for a vehicle is provided with a processing unit, a display, and a rotational drive unit that can rotate a reflector on a prescribed axis. The processing unit includes an estimating unit that estimates planned start of the vehicle by a crew, and when the vehicle is planned to be started, the angle of rotation of the rotational drive unit moves from an initial angle corresponding to an initial position (position of point of origin) of the reflector to a first intermediate angle (first stopping position) between the initial angle and a final angle corresponding to the normal operating position of the reflector. After the vehicle has been actually started, the angle of rotation of the rotational drive unit moves to a final angle from the first intermediate angle.

In a display device, when an ignition switch of a vehicle is off, an external light entering toward a front side of a meter panel is reflected on a smoke layer and a second light shielding layer, and a decorative part and a predetermined zone are, as a whole, viewed through a second opening as being in a ring shape with a width of the second opening and of a color tone based on the smoke layer and the second light shielding layer. When the ignition switch of the vehicle is on, the predetermined zone is illuminated in a predetermined color by a light emitted by a light source with a width of the first opening to be viewed as being wider than the decorative part.
