摘要： A simple optical projection device with a high luminous efficacy has a point light source, a projection screen, a mask that is arranged in the light path upstream of the projection screen and is light-transmissive in some areas, and a light focusing optical lens arranged between the point light source and the mask. The optical lens is selected such that the prolongations of the emerging beams of the optical lens on the side thereof facing the point light source intersect in a virtual perspective center which is more remote from the lens than the point light source.

摘要： An image input/output apparatus includes an image-capturing device that captures an image of a subject placed on a stage and a projection-type display device that generates an image based upon an input image signal and projects the image onto a screen. If the image-capturing device is detected to be in the operating state, an illuminating lamp and a projection lamp are turned on and one of the input terminals is selected at a selection means switch. Thus, the image signal from the image-capturing device is selected and an image based upon the image signal is projected from the projection-type display device.

摘要： A reflection prevention film coats a backside of a stage glass by a vacuum evaporation and coating, etc. A light from a metal halide lamp is not reflected on the back of the stage glass by the reflection preventing film, and is transmitted through the stage glass and is reflected on a surface of the stage glass and a transparent manuscript. The light reflected on the surface of the stage glass and the transparent manuscript enters a projection lens unit and appears as a spot light on a screen, but because the light is not reflected on the backside of the stage glass, so that the amount of the light, which causes the spot light, can be reduced. As a result, the spot light on the screen is inconspicuous.

摘要： An opaque projector includes a light source, a stage through which the light radiating from the light source passes and on which an object is placed, a projection mirror for reflecting light reflected by the object, and a projector lens for gathering the light reflected by the projection mirror to form an image of the object on an image projecting surface located outside of the projector. A reflection mirror for reflecting the light from the light source to illuminate the object is provided on each of the two sides of the projection mirror. The light source is disposed in front of the projeciton mirror and on the inner sides of the reflection mirrors. The reflection mirrors and light source are disposed at positions relative to each other and to the projection mirror which ensures that the light reflected by the reflection mirrors, and regularly reflected by the object and the stage, is not incident on the projection lens and that the real and virtual images of the light source exist outside of the field angle of the projection lens.

摘要： The design of a large copy projector is such that its projection path extends rearwardly and obliquely so that the projector and the viewing screen can be viewed side-by-side. This projector uses an opaque copy sheet characterized by a lower specularly reflecting face that is accessible to the optical system from below but that can be marked from above by a chemical reactant ink from a user's pen or the like. Simultaneously, the upper face is unobstructedly available for direct observation and manual access, and the lower face is unobstrusively available for imaging projection through a folded optical path below the copy sheet and a wide angle projection lens positioned at the side of the copy sheet.

摘要： A large copy projector, in which the presence of elevated optics in front of the screen is avoided, uses opaque sheeting that is adapted to receive related graphic matter on its upper and lower faces. Simultaneously, the upper face is unobstructedly available for direct observation and manual access, and the lower face is unobtrusively available for image projection through a folded optical path below the opaque sheeting and a projection lens positioned elsewhere than directly over the copy. The copy is characterized by a lower specularly reflecting face that is accessible to the optical system from below but that can be marked from above by chemical etching from a user''s pen or the like.
