Definitions
- the present invention relates to a projector system in which a video image, a communal image, etc. can be enlarged, projected and viewed comfortably in a bathroom or sauna room etc. even in a humid environment, and music can also be heard.
- the projector-one projection device has a configuration in which a plurality of projection means for reflecting and projecting the original image from the projector 1 are provided in the cabinet and a plurality of reflecting mirrors, and the guided image light beam is finally projected on the screen. It has been commonly used. However, since it is assumed that the projector-like projection device as described above is projected with the optical axis perpendicular to the screen, if the optical axis perpendicular to the screen can not be maintained, the image is distorted due to trapezoidal distortion or the like. As a result, the installation conditions of the reflecting mirror are greatly restricted, and the area for the optical system such as the projection lens increases, which increases the size in the depth direction with respect to the screen, making the projector projection apparatus thin.
- the present invention provides, among other things, a projector system suitable for use in a humid environment such as a bathroom, and a projector projection apparatus according to the projector system. Disclosure of the invention
- the projector system for a bathroom comprises a bathroom for arranging a glass functioning as a projection surface on at least one surface, a changing room adjacent to the bathroom, and a projector installed in a position facing the glass to project an image.
- the glass is made of laminated glass made of at least two sheets of glass, and at least one piece of glass of the laminated glass is a heating glass having a transparent conductive film, and the laminated glass
