Abstract

A wall structure has a first wall and a second wall that faces the first wall. A part of the second wall or the entire second wall is configured as a rear-projection screen. A projector for projecting an image onto the rear-projection screen is arranged between the first and second walls.

Claims

1. A wall structure comprising:

a first wall;

a second wall that faces the first wall, at least a part of said second wall being configured as a rear-projection screen; and

a projector for projecting an image onto the rear-projection screen, said projector being arranged between the first and second walls.

2. The wall structure according to claim 1, wherein a plurality of the projectors is arranged between the first and second walls.

3. The wall structure according to claim 1, wherein the projector is fixed to a building construction member present between the first and second walls.

4. The wall structure according to claim 1, further comprising a reflecting mirror for reflecting light projected from the projector to make the reflected light incident on the rear-projection screen, said mirror being arranged between the first and second walls.

5. The wall structure according to claim 4, wherein the reflecting mirror is fixed to a building construction member present between the first and second walls.

6. The wall structure according to claim 1, wherein a maintenance port for use in maintenance of the projector is formed at a location on the first wall, said location corresponding to a position at which this projector is arranged.

7. The wall structure according to claim 1, wherein the rear-projection screen and the projector are modularized for any one of each same type and each combination of a plurality of types.

8. A wall structure comprising:

a first wall;

a second wall that faces the first wall, at least a part of said second wall being configured as a rear-projection screen; and

a reflecting mirror for reflecting projection light to make the reflected projection light incident on the rear-projection screen, said mirror being arranged between the first and second walls.

9. The wall structure according to claim 8, wherein a plurality of the reflecting mirrors is arranged between the first and second walls.

10. The wall structure according to claim 8, wherein the reflecting mirror is fixed to a building construction member present between the first and second walls.

11. The wall structure according to claim 8, wherein a projector for projecting an image onto the rear-projection screen is arranged between the first and second walls.

12. The wall structure according to claim 11, wherein the projector is fixed to a building construction member present between the first and second walls.

13. The wall structure according to claim 11, wherein a maintenance port for use in maintenance of the projector is formed at a location on the first wall, said location corresponding to a position at which this projector is arranged.

14. The wall structure according to claim 8, wherein the projector is arranged out of a space between the first and second walls.

15. The wall structure according to claim 8, wherein the rear-projection screen and the reflecting mirror are modularized for any one of each type and each combination of a plurality of types.
