[0002]
[Prior art]
2. Description of the Related Art Projector devices that project video images and computer images have been reduced in size, weight, and image quality due to recent advances in image display panel technology. In general households, the Internet and DVD have become widespread, and there is an increasing need to view these images through a projector device.
[0003]
[Problems to be solved by the invention]
However, at present, the projector device is used only by some enthusiasts and users who can afford the indoor space. The reasons are as follows.
[0004]
{Circle around (1)} Although the size of the projector device has been reduced as described above, it is not preferable to permanently install the projector device in a space where a consumer moves. Further, even when the projector device is installed only at the time of use, it is complicated to secure an installation space every time the projector device is used.
[0005]
{Circle around (2)} In order to appreciate the image of the projector device, it is necessary to secure a space for installing the screen, but it is not always easy to secure this space in a living room which is a multipurpose and shared space. . That is, the installation space for the screen is generally secured on or near the wall surface, but in this position furniture such as storage and displays such as a display for producing a sense of life are usually arranged at this position. In many cases, the elimination of such furniture and fixtures impairs the mental satisfaction of consumers, and it is difficult to secure a space for installing the screen.
[0006]
{Circle over (3)} In order to ensure the contrast of the image projected on the screen, a certain degree of “darkness” is required in the projection area of the image light projected from the projector device. However, in a multipurpose and shared space such as a living room, it is difficult to secure “darkness” for a long time.
[0007]
{Circle around (4)} Further, the “darkness” itself mentally reduces the enjoyment of watching images in the living room.
[0008]
To summarize the above, (1) and (2) are problems relating to “installation space”, and (3) and (4) are problems relating to “brightness”.
[0009]
SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and has as its object to provide a projector device and a projector device which solves the problem of "installation space" of a screen. It is an object of the present invention to provide a projector device that solves the problem of “brightness” when viewing a video by the projector device.
