摘要： According to an embodiment, a projection device includes: a light source; an optical scanning unit that includes a base unit, a driver fixed to the base unit, and a reflective unit supported by the driver and that drives the reflective unit to scan light from the light source; and a scanned unit configured to be scanned with the light from the optical scanning unit so that a projection image is formed on the scanned unit. The projection device further includes an attachment unit for attaching the projection device to a setting unit of a setting object on which the projection device is set. The attachment unit attaches the projection device to the setting unit such that a direction in which vibration caused by the setting object is equal to or smaller than a predetermined value and a reflective surface of the reflective unit are approximately perpendicular to each other.

摘要： A display device and a mobile object. The display device is installable in a mobile object, and includes a light source, an image former to receive light emitted from the light source and output image light that forms an image, a screen on which the image light forms the image, a housing that houses the light source and the image former, and a holding member to hold the screen. The holding member is attached to the housing with a normal direction of a surface of the screen intersecting with a vertical direction and with a front-and-rear direction of the mobile object. A width of the housing is narrower than a width of the holding member. The mobile object includes the display device, a front windshield to reflect the image light, and an image-forming optical system to project the image light projected from the screen toward the front windshield.

摘要： An optical device includes a rectangular parallelepiped prism including a reflection-transmission surface for reflecting and transmitting light fluxes, a seating surface provided so that a bottom surface of the prism is fixed by an adhesive, and a groove portion provided in a part of the periphery of the seating surface. When the prism is fixed to the seating surface by the adhesive, the groove portion is configured to be capable of receiving the adhesive protruded from between the bottom surface of the prism and the seating surface when the prism is pressed against a first positioning member for determining a position of the prism so that a first side face of the prism is along a predetermined straight line and against a second positioning member for restricting a second side face orthogonal to the first side face of the prism from moving in the direction of the straight line.
