  • Publication number: 20120013858
    Abstract: A dimmer has a driving source, a driven body that is reciprocatingly moved by driving force generated by the driving source, and a transmission mechanism that transmits the driving force generated by the driving source. The transmission mechanism includes at least one rotary gear, and a conversion gear that converts the rotational motion of the rotary gear into linear motion. The light shielding plate is integrally provided with a drive pin in parallel with a rotating shaft of a light shielding plate. The driven body engages with the drive pin. The drive pin is rotated about the rotating shaft of the light shielding plate in association with the reciprocating movement of the driven body to cause the light shielding plate to rotate.

  • Publication number: 20100214538
    Abstract: An optical unit (1) is disclosed that is equipped with a pair of integrator lenses (11 and 14) secured to a holder (12), the optical unit (1) including a first frame-shaped metal plate (10) secured to the holder (12) in a state in which a portion of the principal surface contacts with a first surface (A) of the holder (12) and a second frame-shaped metal plate (15) secured to the holder (12) in a state in which a portion of the principal surface contacts with a second surface (B) of the holder (12). One lens array (11) is positioned with respect to the optical axis direction by securing the lens formation surface to an area which is a part of the surface of the principal surface of frame-shaped metal plate (10) and which does not contact with the first surface (A) of the holder (12).

  • Patent number: 7382538
    Abstract: An optical unit has a first lens holder holding a first lens and a second lens holder holding a second lens, the first lens holder and the second lens holder being mounted on a common lens base. The first lens holder is movable in the direction of one side of the exit end face of a light tunnel, and the second lens holder is movable in the direction of another side, adjacent to the one side, of the exit end face of a light tunnel. The first lens holder and the second lens holder are independently moved to bring an illuminating light area on a DMD, as an image forming device, into alignment with an image forming area on the DMD. The illuminating light area can thus be accurately positioned in the image forming area on the DMD. The optical unit has a high light utilization efficiency and can easily be operated for positional adjustment of the illuminating light area. The optical unit is incorporated in a projection display apparatus.

  • Patent number: 6877862
    Abstract: A reflecting mirror 4d has a rotation axis 7 which is inserted into a bearing 8 of a case 1. Accordingly, the reflecting mirror 4d is capable of rotating with respect to the case 1 and only the reflecting mirror 4d is capable of adjusting the set up angle ? made with the case 1. When the set up angle is changed, the reflecting angle of the projected ray on the reflecting mirror 4d is also changed. Therefore, the launching angle of the projected ray 5 with respect to the case 1 can be adjusted.
