摘要: A projection type liquid crystal display device includes a light source and condenser lenses for emitting two groups of beams of light which orthogonally cross each other. A first device is disposed in the path of one of the groups of beams and comprises a liquid crystal panel and at least one polarization plate to transmit P-wave polarized light. A second device is disposed in a path of the other group of beams of light and comprises a liquid crystal panel and at least one polarization plate to transmit P-wave polarized light. A dichroic mirror disposed to receive light from the first and second devices synthesizes the P-wave polarized light by transmitting P-wave polarized light from the first device and for reflecting the P-wave polarized light from the second device.

摘要: Light emitted from a single light source is split into beams of bidirectional parallel light which are orthogonal to each other. Beams of the parallel light in each direction are reflected by a reflection optical system in such a direction that they become orthogonal to each other. A dichroic mirror is disposed at a point of intersection thereof and liquid crystal panels are provided between each individual reflection optical system and the dichroic mirror resulting in a low cost device which can be structurally miniaturized and which requires less process steps in fabrication.

摘要: A projection type liquid crystal display device includes a light source and condenser lenses for emitting two beams of light which are orthogonal to each other. One of the light beams passes through a liquid crystal panel of one color, and the other light beam is further divided into two light beams each of which passes through liquid crystal panels of other colors. The three light beams are then synthesized by dichroic mirrors and fed to a projection lens system.

摘要: An instant photocopying apparatus has a rod lens array for imaging fine areas of a manuscript on a photosensitive surface of an instant film. The apparatus has a carrier which is movable in a direction parallel to the manuscript. A flourescent lamp illuminates the manuscript. A filter holder is mounted to the lower end of the carrier, and an optical filter is provided for covering a light incidence portion of the rod lens array. The filter is removably mounted so as to enable changing the exposure and tint of the photosensitive surface of the instant film by mounting or dismounting the filter.

摘要: An instant photocopying apparatus includes a case placed on a document and a base plate formed with a window through which the document is visible and which is pivotably mounted on the case. An opening portion is formed in an upper surface of the case in superimposed positional relationship with the window. An instant photosensitive material is provided which has a photosensitive surface and a printing surface for forming an inverted image of an image formed on the photosensitive surface as a visible image. A cassette accommodates the instant photosensitive material, and a cassette holder is provided on an upper surface of the case and into which the cassette is chargeable. The case incorporates an optical device for forming a narrow region of the document on the photosensitive surface as an erecting real image, a driving arrangement for moving the optical means in parallel to the document, a light source for illuminating the document with light and a shading arrangement for preventing unnecessary light from falling on the photosensitive surface.
