摘要： An illumination housing includes a glass platen for supporting a document, the platen having at least one surface area uniformly roughened. In one embodiment, both surfaces are uniformly roughened by an etching process. The surface of the platen are thus rendered diffusely reflective to specular hot or cold light spots formed by light reflected from optical components within the illumination system and compensates for platen-derived specular reflections into the projection lens.

摘要： Pre-polygon optics are provided which consist of a compact design such that the number of pre-polygon elements in the pre-polygon optics is reduced while achieving desired light beam characteristic. The pre-polygon optics may consist of a hybrid toroidal diffractive optical element, refractive cross-cylindrical optical elements, refractive spherical and cylindrical optical elements, a refractive sagittal cylindrical optical element or a refractive tangential cylindrical optical element. Accordingly, advantages such as lower cost and ease of alignment are achieved.

摘要： In an electronic printer which utilizes an image write bar, a control circuit is provided to compensate for the effects of vibration in a rotating photoconductive member, typically a photoreceptor drum. In one embodiment an encoder is positioned so as to detect spatial displacements of indicia affixed to the photoconductor surface, Correction signals are generated and sent to control circuits which adjust the on/off timing of the write bar operation and/or the intensity of the image bar output. This adjustment results in compensation for the effects of photoconductor vibration.

摘要： An image bar recording system, which, in a preferred embodiment, utilizes an LED image bar, with associated circuitry for recognizing which of individual LEDs comprising the print bar are out of registration in the slow scan, process direction of a moving photoreceptor upon which the image is to be recorded. Modification of the drive circuits to the individual LEDs results in energization signals being delayed to the identified, misregistered LEDs resulting in an exposure line which is in correct slow scan registration.According to another aspect of the invention, the delayed signals are selectively applied to intentionally cause a misregistered exposure line when using the image bar in conjunction with a raster output scan system.

摘要： A short focal length lens array has a plurality of lenslets formed within the body of a photosensitive glass. The lenslets have areas which are oriented such that they tilt away from each other from the center out to the array edges.

A one or two row embodiment is disclosed suitable for incremental scanning of a document at image planes. A further full frame lens array is disclosed for providing full frame exposure of a document at various selected magnifications.

摘要： An illumination system for a document copying machine including an optical cavity having interior walls coated with a white, diffusely reflecting material. One end of the cavity contains a platen for positioning a document to be copied while the opposing end contains a lens for forming an image of the document on a light sensitive image plane. Illumination from a single flash illumination source located within the cavity, undergoes multiple reflections from the walls resulting in a uniform diffuse illumination of the document. An optical element is positioned above the lamp to prevent direct light from striking the platen and, in a preferred embodiment, has an aperture therein for increasing illumination of the platen area overlying the lamp-blocker mounting.

摘要： An optical system in which a movable photosensitive member is exposed to a light image of an original document. The optical system includes a light source which illuminates a screen having at least two adjacent spaced rows of opaque dots. Movement of the photosensitive member controls activation of the light source. The light source is activated periodically and responds to the photosensitive member moving a distance corresponding to the distance between adjacent rows of opaque dots on the screen.

摘要： A system for concurrently imaging the first and second sides of different sequential duplex documents in alternating image lines alternating between the first and second imaging stations. This system is shown in a system for imaging both of the first and second opposing sides of duplex documents with higher productivity, with a generally "V" shaped low profile document sheet feeding path with first and second arms merging at a base position having a document reversing system, for sequentially feeding documents from an input tray through the first arm to the base position, and then back through the second arm to an output tray. A first imaging station is in the first arm for imaging the first sides of the documents, and a second imaging station is in the second arm for imaging the second sides. Both imaging stations have a simple, partially shared fixed elements optical system mounted entirely inside the document path, which can share a single electro-optical digital imager. The duplex documents are not inverted, yet are returned to the output tray in the same orientation as the stack in the overlying input tray. Compatible simplex document copying can also be provided.
