    Abstract: PROBLEM TO BE SOLVED: To improve the drawback that the height of a projector is unavoidably and considerably higher than the display screen height on the screen. SOLUTION: In a rear projection display device having a display device, a lighting optical system for lighting the display device, and a projection optical system for projecting the light from the display device to the screen, the device includes a plane mirror on the back side of the upper end part of the screen and a curved surface mirror on the backside of the lower end part of the screen on the opposite side of the plane mirror position, in which the light rays of the outermost area on the opposite side of the screen, among incident light fluxes from the curved surface mirror to the plane mirror, are substantially parallel to the screen.

    Abstract: PROBLEM TO BE SOLVED: To provide a projector device in which handleability, safety, and stable projection are taken into account. SOLUTION: The electrical or mechanical characteristics of the projector device are made different according to a position where a projector projecting part 1 is located with respect to a projector base 2, that is, depending on whether the projector projecting part 1 is in a stored position or a projecting position. For example, when the projector projecting part 1 is in the projecting position, air inlets 13 are opened, and when the projector projecting part 1 is in the stored position, the air inlets 14 are closed. Thus, the mechanical characteristics are made different between them. COPYRIGHT: (C)2005,JPO&NCIPI

    解决方案：投影仪设备的电气或机械特性根据投影机投影部1相对于投影仪基座2所在的位置而变化，即根据投影仪投影部1是否处于 存储位置或突出位置。 例如，当投影机突出部分1处于突出位置时，空气入口13打开，并且当投影仪突出部分1处于存储位置时，空气入口14关闭。 因此，它们之间的机械特性不同。 版权所有（C）2005，JPO＆NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a zoom lens for projection by which an optical modulator provided with a plurality elements for changing light reflection directions and generating an image projects an image to a screen.
    SOLUTION: A zoom lens system 5 is provided with a five-group configuration being negative-positive-positive-negative-positive from a screen side, including a fixed fifth lens group G5 arranged at a light bulb 2 side and used as a field lens through which light 11 for illumination and projection light 12 goes and a fixed first lens group G1 for focusing. In the lens system 5, a third lens group G3 moves largely during variable power, and a second lens group G2 and a fourth group G4 have small moving distance. Thereby, in the zoom lens system, the movement of an incident pupil with respect to the projection light outputted from the bulb light becomes small, effective projection light is efficiently engulfed, and a bright and clear image can be projected.
