Therefore, the installation work can be easily performed.

It is explanatory drawing which shows one Example of the handle of the door with a display apparatus of this invention. It is explanatory drawing which shows the other example of the handle of the door with a display apparatus of this invention.

Next, an embodiment of a handle for a door with a display device according to the present invention will be described with reference to FIG.
Handles 2 are provided on both sides of the door 1. The handle 2 may or may not have an opening / closing mechanism like a normal door knob. The handle 2 has a substantially hemispherical shape, and is provided with a screen 3 on the surface and a projector 4 serving as a projection unit for projecting an image onto the screen 3. As the projector 4, for example, a scanning laser projector can be used. Moreover, an LED projector may be used.

  The screen 3 is formed of a transparent body having a thickness of about 5 mm, the surface is a mirror surface (smooth surface), and the inner surface is a diffusion surface. The material of the screen 3 is not limited as long as it is a transparent body, but for example, synthetic resin or glass can be used.

  A CCD / C-MOS camera 5 serving as a photographing means is provided in the vicinity of the handle 2 of the door 1 so that an image outside the door 1 can be acquired. The cameras 5 are connected to the projector 4 of the handle 2 located on the opposite surface of the door 1. Note that the attachment position of the camera 5 is not limited to the vicinity of the handle 2, and the installation position can be selected as appropriate depending on the video to be acquired.

  Since it is configured in this way, the image captured by the camera 5 is projected onto the screen 3 by the projector 4. Since the screen 3 has a diffusing surface on the inner surface and a mirror surface, the image projected from the projector 4 is displayed on the screen 3 so that it can be seen from the outside. The visible image looks best in front, but the visible image does not change depending on the viewpoint.

  Handles 2 are provided on both sides of the door 1. The handle 2 may or may not have an opening / closing mechanism like a normal door knob.
