摘要： An opaque adapter for an overhead projector uses a hood with clamshell doors to provide generous access to the projector stage during transparency projection and efficient light shielding during opaque projection. The clamshell doors are oriented upon hinges slanted to the vertical so as to rise away from the stage when opened. Spring devices offset the gravitational forces on the doors, allowing rapid motor actuation with very little power. Dual dichroic optics maintain a cool stage despite high light intensity, and internal baffles further increase brightness.
摘要翻译：高架投影仪的不透明适配器在透明度投影期间使用带有蛤壳式门的罩罩，以提供对投影机舞台的大量访问，并在不透明投影期间提供高效的遮光。蛤壳门定向为垂直于倾斜的铰链，以便在打开时从舞台上升。弹簧装置抵消门上的重力，允许以很小的功率快速的电机致动。双重二向色光学器件保持了很高的亮度，而且内部的挡板进一步增加亮度。

摘要： A projection and display apparatus comprising a light source (1) and a projecting means (2) for projecting light beams from the light source towards a screen. The apparatus comprises a first light-path (6) including an overhead printer sheet (16) to be displayed on the screen and a second light-path (7) including a slide projector film (23) to be displayed on the screen. The light beams are selectively directed towards either of the light-paths (6, 7). Liquid crystal shutters (15, 27) are interposed in each light-path and controlled by an electric voltage to selectively prevent or allow the passage of the light beams for selecting either of overhead printer sheet or slide projector film.

摘要： A projector comprises a substantially horizontal table, a substantially centrally above the table arranged projection optics (2), a light source (3) which is located above the table and arranged to illuminate the table, a deflexion minor (4) for substantially horizontal deflexion of a light radiating vertically upwardly from the table, and a light shaft (5) which at least partially screens off the area between the optics (2) and the table (1) from the surroundings and is characterized in that a covering (6a) is arranged to be laid out over the table surface in that the upwardly facing surface of the laid out covering is light-reflecting, while the table surface is light-absorbing preferably black and mat, alternatively that the upwardly facing surface of the laid out covering is light-absorbing while the table surface is arranged to emit light vertically upwardly.

摘要： An imaging device has: a video camera that takes a video of an imaging object; a camera holder that supports the video camera at a position of imaging the imaging object; an output module that outputs the video taken by the video camera; and an image processing module configured to superimpose a predetermined figure at a reference point of expanded display or contracted display in the video output by the output module. The imaging device of this arrangement enables easy adjustment of an expansion display area of an imaging object in the course of outputting a video signal representing a taken video of the imaging object to an external device.

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.

摘要： Special purpose reflex reflecting sheets are characterized by closely packed refracting microspheres and interspersed pigment particles, both of which are held in fixed optical relation to a metallic reflecting stratum by a thin adhesive stratum. In one form, the product is designed to return light without substantial diffusion when its angle of incidence is approximately normal and to return light with substantial diffusion when its angle of incidence is substantially oblique. This product is particularly useful for the combined purposes of direct viewing in terms of diffuse light controlled by the pigment and of episcopic projection onto a viewing screen in terms of directed light controlled by the metallic reflecting stratum.
