  • Patent number: 7207676
    Abstract: A reflection type projector apparatus uses polarized beam filters that are resistant to fluctuations in incident angle as the light beam splitting elements and in which are provided for the blue color beam a blue color use liquid crystal reflection panel, a polarized beam filter, a linear polarization plate, and a ½ wavelength plate arranged at one side face of a cross prism, with a blue color beam emitted toward the blue color use liquid crystal reflection panel. The blue color beam passes through the polarized beam filter, striking the blue color use liquid crystal reflection panel, and is modulated when reflected. The blue color modulated beam is reflected toward the cross prism at the polarized beam filter, and then passes through the linear polarization plate and the ½ wavelength plate, strikes the cross prism, and is projected to the screen by a projection lens.

  • Publication number: 20060209272
    Abstract: An image projection apparatus having an adjuster mechanism with a projecting member projecting from a bottom surface of the case to adjust the elevation angle of a projection lens and an opening/closing member located at a front surface of said projection lens for opening or closing the projection opening. The adjuster mechanism uses an electric motor to move the projecting member up and down. The opening/closing member is opened/closed using a linkage mechanism linked to the adjuster mechanism.
