    • An imager is shifted with respect to an optical axis of a refractive optical system. Thereby, a throw distance of a projector is shortened. A wavelength-selective half wavelength plate for rotating a polarization direction of green light beams is disposed between a dichroic prism and the refractive optical system in such a manner that the polarization direction of the green light beams is in parallel to the shifting direction. Thereby, the green light beams are incident onto the refractive optical system as P-polarized beams, whereby a transmittance of the green light beams in the refractive optical system is increased, while suppressing lowering of the light amount of the green light beams, and color non-uniformity resulting from lowering of the light amount of the green light beams.
    • 成像器相对于折射光学系统的光轴移动。 因此,投影机的投射距离缩短。 用于旋转绿色光束的偏振方向的波长选择性半波长板以这样的方式设置在分色棱镜和折射光学系统之间,使得绿色光束的偏振方向平行于移动方向。 由此,绿色光束作为P偏振光束入射到折射光学系统上,从而在折射光学系统中的绿色光束的透射率增加,同时抑制绿色光束的光量的降低和颜色 由于绿色光束的光量的降低而导致的不均匀性。

    • Herein disclosed is an improved direction changing mechanism used in a shift control mechanism of a transverse manual transmission. The direction changing mechanism comprises a drive member movable together with the control rod; and at least one driven member movable together with the shift fork. The driven member is formed with a rectangular recess into which a head portion of the drive member is insertable under a certain condition so that upon selecting operation, the head portion of the drive member is put in the recess of the driven member and upon shifting operation, the head portion of the drive member abuts against one of the side walls of the recess thereby to move the driven member in a certain direction thereby completing a gear coupling. The head portion of the drive member is so sized and constructed that when the drive member assumes its rest or neutral position, the head portion is spacedly put in the recess without contacting the driven member, while, when the drive member assumes its operative position to complete the gear coupling, the head portion contact both the side walls of the recess.

    • A light source apparatus includes: a light source; a reflection rotary body; an optical path changing element; and a polarization controller. The polarization controller controls polarization of the first color component light to a different polarization by means of transmission of the first color component light emitted from the light source and by means of transmission of the first color component light reflected by the reflection rotary body. The optical path changing element guides the first color component light reflected by the reflection rotary body, in a direction different from a direction of the first color component light emitted from the light source, in accordance with the polarization of the first color component light modulated by the polarization controller.
