  • Table type large-size imaging apparatus
    Patent number: 8248542
    Abstract: A table type large-size imaging apparatus in which an imaging screen and a reflector are installed in front and rear end positions of a table type case with an inclination angle that extends in directions downwardly away from the upper surface. The reflector and imaging screen are arranged to then reflect an image in a direction parallel to an upper surface of the table type case to allow a viewer to watch an image formed on the screen through a transparent window provided at a top of the table type case. The viewer's watching distance and the image projection distance are overlapped within the table type case, to achieve a maximum screen size with a minimum table size. With this configuration, a viewer who is located close to the imaging apparatus in the form of a table is able to appreciate the vivid large-size image with a downward viewing angle.
