摘要： A method of making a two-dimensional exposure on an object with a plurality of light beams by a main scan for making scans with the light beams in one direction and a sub-scan for making scans with the light beams in a direction intersecting the direction of the main scan. In a distance detecting step, a distance between a portion exposed to at least one of the plurality of light beams and a portion exposed to respective other light beams is detected when respective the plurality of light beams are exposed toward an object. In an exposure start-timing changing step, the timing for starting an exposure to be effected by at least one of the main scan and sub-scan made with respective the plurality of light beams is changed according to the distance in such a manner that the positions of the portions exposed to the plurality of light beams are substantially identical.

摘要： An optical beam scanning apparatus comprises means of modulating the optical power of a laser beam produced by a laser beam source, means of shaping the laser beam profile, and means of deflecting and focusing the shaped laser beam on a scanning plane. The optical power of the laser beam is varied in synchronism with the variation of the optical power distribution so that the peak level of optical power of the laser beam is kept constant. The optical power of the laser beam on the photosensitive drum is kept constant irrespective of the beam diameter, and printed dots of intended diameters can be produced, whereby fine multi-tone images can be printed stably.

摘要： A trapping technique which accepts a Postscript or other page description language (PDL) file and outputs a file in PDL format having the correct traps. The input page is first divided into sub-portions, or tiles, and the tiles are individually processed by evaluating the input file in a corresponding clipping window. Each tile is then analyzed to determine where edges exist. The edge data is fed to an edge converter which produces a list of color transitions consisting of the analytic description of each edge and the color information along the sides of the edge. The color transition information is fed to a trapping analyzer which generates trap vectors in accordance with a set of desired trapping rules. The trap vectors are then converted to PDL form. As a final step, the trap vectors are added to the original PDL file. The final trapped page may be printed on standard typesetters without the need for special trap generator hardware.

摘要： A printing device employs a semiconductor laser source for producing a laser beam, and a semiconductor-laser-pumped solid-state laser. The solid-state laser includes an optical resonator, such as a nonlinear optical element for effecting wavelength conversion, and a solid-state laser material disposed therein. The solid-state laser material is optically pumped by the laser beam from the semiconductor laser source and produces a laser beam to be applied onto a photosensitive sheet of paper. Responsive to print data, the intensity of the laser beam from the semiconductor laser source is varied between a first intensity level and a second intensity level. The photosensitive sheet of paper is insensitive to the laser beam when the laser beam from the semiconductor laser source is at the first intensity level, whereas it is sensitive to the laser beam when the laser beam from the semiconductor laser source is at the second intensity level.

摘要： An electrophotographic color image forming method whereby black, yellow, magenta and cyan toner images are superimposed on a photoconductor (54) to transfer to paper, exposure being changed between black and color in a method in which development of black is performed by a contact developing method, and development of color by a direct current electric field projection developing method. Also, in exposure for color, the exposure amount is adjusted between highlight and shadow areas. A full color image of high saturation with good balance between black and color components is reproduced by changing the exposure amount between black and color. It is also possible to obtain a color image with good reproducibility of highlight areas as well as shadow areas.

摘要： A device applicable to a laser beam printer, color printer, digital copier, facsimile machine or similar image recorder for controlling the output level of a scanning beam to a predetermined level. The device sets the output level of the scanning beam in response to data fed thereto from the outside, thereby coping with changes in image forming conditions and changes in various characteristics due to aging. The device incorporated in a color printer, for example, sets the output levels of individual laser beams in matching relation to the characteristics to individual colors.

摘要： A laser printer is disclosed which is adapted to be used for color imaging. The printer comprises three diode lasers, each of which emits a light beam at a different wavelength. Each of the light beams passes along a separate channel to a pair of dichroic plates which combine the three beams into a single combined beam. The combined beam is scanned by a polygon onto a receiving medium which is sensitive to the infrared. Two cylindrical lenses in each channel are used to focus the beam in the channel at a registration plane located after the beam combining means. An optical relay is used to transfer the combined beam from the registration plane to the polygon and to focus the beam in a cross-scan direction on the polygon. The polygon is optically conjugated to the image plane in order to achieve cross-scan error correction.

摘要： An optical printing apparatus is provided for use in color printing systems wherein an image is projected by a fiber-optic faceplate CRT onto an imaging sheet which contains a layer of pressure rupturable capsules, each capsule encapsulating a photoreactive composition and a chromogenic material. The image is focused on a display screen of the fiber-optic faceplate CRT and transmitted through a plurality of optical fibers in parallel so that the image can be sharply focused on the imaging sheet. A scanning technique permits multiple exposures of the imaging sheet and results in the development of a color image having distinct color gradations.

摘要： An image recording system including a host control unit for generating image data and a printer apparatus for forming an image on a sheet of paper in accordance with the image data. The printer apparatus has a function of dividing the image into two image areas with respect to a boundary extending in a direction orthogonal to the direction of transport of the paper and of forming each of the image areas with different colors. The host control unit is adapted to supply to the printer apparatus a boundary signal indicative of the boundary of the image areas. The printer apparatus has a controller for automatically selecting a first orientation in which the lengthwise direction of the sheet is the direction of transport when the boundary signal indicates a boundary extending in the widthwise direction of the sheet and for automatically selecting a second orientation in which the widthwise direction of the sheet of paper when the boundary signal indicates a boundary extending in the lengthwise direction of the sheet.

摘要： A laser printer records an image on a medium as a function of digital data which is received at an input data rate. A laser beam is used for recording pixels of the image on the medium while the medium is advanced in a longitudinal direction at a controlled uniform rate. The pixels are recorded by scanning the beam across the medium in a transverse direction, at a scan velocity, using a multifaceted, rotating mirror which reflects the beam onto the medium. The scan velocity is proportional to the angular velocity of the rotating mirror. Beam intensity is modulated as a function of the input digital data. In order for the average data rate of recording to be compatible with the input data rate while maintaining a high instantaneous scan velocity, the beam is scanned across the medium by only one of every N-facets of the rotating mirror.
