Patent Document 1 states that the video for driving and the video for parking / stopping are switched depending on the traveling state of the vehicle, the emergency response video is displayed when an emergency signal is received when a disaster occurs, and the vehicle provides an emergency response video. It describes displaying relay images sent from relay cameras provided at a distance, displaying Internet images received via Internet connection means, etc., and is expected to be used in various applications. .. However, the structure of the vehicle is such that a video display is mounted on the side surface of a box-shaped loading platform, and the surface of the video display is always exposed to the outside (outdoor) of the vehicle. Therefore, it is necessary to adopt a waterproof structure so that it will not break down even if it gets wet with rainwater or the like, and there is a problem that the structure becomes complicated and maintenance is lacking. In addition, since dust and dirt easily adhere to the screen, not only is it time-consuming to clean, but it is also exposed to wind and rain, and is easily damaged by collisions of flying objects and external impacts, resulting in poor durability. There are also challenges. Further, since the video display is fixed to the loading platform and the height cannot be adjusted, there is a problem that the viewing range of the video is limited.
On the other hand, in Patent Document 2, since the screen is installed inside the box-type loading platform, the door of the box-type loading platform is opened when the image is displayed, and the door is closed when the image is not displayed. It is possible to protect the display screen from rain and wind and prevent the display screen from becoming difficult to see due to dirt such as dust and dirt. However, in the case of a structure in which the door on the side surface of the box-shaped loading platform is expanded and opened upward, it is necessary to secure a sufficient space around the vehicle so that the expanded door does not collide with surrounding structures and the like. In particular, there is a problem that the height is easily restricted and the place of use is limited. In addition, even if the screen is equipped with an elevating mechanism and the screen is raised so that the image can be seen from a distant place, the movable range is limited by the door deployed upward, and the problem is that it lacks versatility. There is. Further, in a configuration in which image light is projected on a screen using a projection type display device (projector) as in Patent Document 2, the image becomes difficult to see because external light such as direct sunlight hits the surface of the screen. There is a drawback. Regarding this point, it is also described that the position of the door that expands upward is adjusted so that the screen is not exposed to outside light, and that a sunshade member is attached to the door, but the outdoor brightness during the day and It is not possible to sufficiently cope with reflected light and the like emitted from various directions. Patent Document 2 also describes a method of opening and closing a shutter-shaped door by sliding it in the vertical direction. However, a screen can be installed by installing a door winding mechanism above a box-shaped loading platform. As the space is reduced and the screen becomes smaller, it becomes difficult to mount the screen raising / lowering mechanism, and there is a problem that the functionality is lowered. Further, there is a problem that visibility is lacking because the outside light cannot be shielded by the door.

The present invention has been made in view of such circumstances. It has a compact structure, is not subject to restrictions on the place of use, can protect the display surface from dirt such as rainwater and dust, and external force except when in use, and can be maintained.
