Abstract: A head mount display includes a display unit, a power source unit, a holding unit, and an adopter. The display unit displays a screen in a visibility direction of a user using the head mount display. The power source unit drives the display unit and includes a circuit board and a battery. The holding unit connects the display unit and the power source unit. The display is mounted on the head or a helmet of the user by the adopter. In the head mount display, the battery and the circuit board of the power source unit are disposed across a ventilation unit, and the ventilation unit is formed in an overhead direction of the user.

Abstract: A head mounted display uses an image projection device comprising: an image generation unit for generating an image; a projection unit for guiding the image generated by the image generation unit to an observer's eyes; and a support for linking the projection unit and the image generation unit. The projection unit has a lens function which makes it easiest to see an image generated by the projection unit at a distance (Lobj) within a range between 30 cm and 3 m. Thereby, the image projection device operates at high resolution, has reduced size and weight, and reduces energy consumption.

Abstract: A video projection device 001 includes a video generation section 041 that has a micro display element 003 which generates video and an illuminating optical system 002 which illuminates a micro display element; projection section 043 that project the video which is generated by the video generation section onto the eyes of a user through an eyepiece section; and a mechanical support section 042 that connects the video generation section to the projection section using a housing section. The mechanical support section includes at least one transparent area 011 that is surrounded by the housing section, and penetrates in a direction parallel to a direction in which the video from the projection section is projected. The illuminating optical system includes a light source that emits light in a plurality of wavelength bands, and a controller 440 that controls the output of the light source.
