摘要： An aperture plate is disposed between a reduction optical system (imaging optical system) and a light source unit in which a plurality of light source parts each emitting a light beam are arranged in a predetermined arrangement pattern. In the aperture plate, a plurality of apertures are arranged in the same pattern as the arrangement pattern of the light source parts. Light beams from the light source parts are directed toward the reduction optical system through the apertures which face the respective light source parts so that reduction images of the apertures are formed on a photosensitive material. Even if the light source parts are located a little displaced from a predetermined arrangement pattern, images of the apertures will be focused on a photosensitive material. This enables easy adjustment of the locations of the light source parts and recording of a high quality image.

摘要： A combined raster input and output scanner employing spaced document reading and copy printing arrays at a common read/write station. The document to be read and the copy to be printed are disposed in back to back relation and fed simultaneously to the read/write station between the document reading and copy printing arrays. The image reading array is a monolithic full line chip having dual staggered rows of image sensors with individual lenslets for focusing each sensor onto a scan line at the read/write station. To reduce cost, a minimum number of image sensors with relatively wide spacing therebetween is used. To offset loss of resolution, the reading array is movable between a first reading position where one-half of the document line is scanned and a second reading position where the remainder of the line is scanned. The copy printing array comprises a full line of ink jet nozzles, the number and disposition of the ink jet nozzles corresponding to the image sensors, the copy printing array being similarly movable between first and second copy printing positions concurrently with the reading array to thereby print the line in similar half-line increments.

摘要： Method and apparatus for plotting a raster image on a plane record carrier. A computer-stored raster image includes raster points and is convertable into controllable, raster-point related light beams in which picture elements corresponding to the raster points are plotted on the record carrier. The method includes dividing the computer raster image into matrix-like imaginary computer raster image subareas, dividing the raster image of the record carrier into matrix-like imaginary raster image subareas of the record carrier, and associating the subareas of the computer raster image and the subareas of the raster image of the record carrier with each other. The method further includes dividing the computer raster image subareas into n matrix-like imaginary raster point positions, dividing the raster image subareas of the record carrier into n matrix-like imaginary picture element positions, and associating the n matrix-like picture element positions with the n matrix-like raster point positions. Further, the method provides for successively plotting the picture elements that correspond with the raster points in successive time intervals Tq, wherein q represents values 1−n, and simultaneously plotting, during a qth time interval, respective qth picture elements associated with a qth picture element position of the raster image subareas of the record carrier, and moving, during the qth time interval, an aperture matrix that includes matrix-like arranged aperture matrix fields, each having an aperture for passing a light beam, and aligning each aperture with the qth picture element position to plot the respective qth picture element. The apparatus includes the matrix-like arrangements of the computer raster image, the computer raster image subareas, the raster image of the record carrier, and the raster image subareas of the record carrier, and the aperture field.

摘要： A system 10 for independently illuminating a plurality of areas on an object 26 such as a printer drum is disclosed herein. The system 10 includes a light source 12 such as an LED or a plurality of LEDs. A spatial light modulator 14, which may be a movable mirror device, for receives light from the light source 12 and reflects selected portions of the light. The spatial light modulator 14 includes at least n rows of independently modulated pixels wherein a mask prevents more than 1/nth of each the rows from receiving and reflecting light at any point in time. The light from the spatial light modulator 14 is imaged (e.g., with imaging lens 24) onto rows and columns of the object 26 to be illuminated. The object 26 is illuminated in a way that each column is illuminated by a corresponding row of pixels.

摘要： An apparatus for recording an image with a plurality of laser beams on a recording surface comprises a plurality of laser source units each generating a laser beam and a first lens for directing the laser beam from each one of the plurality of laser source units to the recording surface. In the apparatus, the laser source units are each disposed on a holding member in such a manner that the principal ray of the laser beam therefrom passes through a front focal point of the first lens. Thus, the apparatus is advantageous in that it is not necessary to employ an enlarged lens despite increase in the number of the laser source units, or the channel numbers.
