Retractable image projecting system |
摘要 |
An image projecting system for mounting in a hidden location such as a ceiling or a piece of furniture such as a desk. The system includes an image producing apparatus and a plurality of optical components. At least one of the optical components is a mirror that can move between two positions. In the first position the mirror is flush with the ceiling or the desk so that the system is hidden from view. In the second position the mirror is at an angle to the ceiling or the desk so as to project an image externally of the hidden location and onto a screen or other surface.
