Abstract:
A slip processing system operates to read necessary data from a separate sheet or sheets, and identifies, from the data read, certain letters or numerals that characterize the slip to be prepared. The apparatus includes a device selecting a predetermined visual mark or mode according to the results of identification, a memory storing the image of the data read, an editing device for allocating the stored data and selected mark or mode to respective locations on predetermined slip forms, and a printer for printing the edited data onto a prescribed slip sheet.
Abstract:
In the image formation effected by combining different original images, a plurality of original images to be combined are photoelectrically converted into time-sequential signals and stored in predetermined memory means, the memory signals corresponding to the original images stored in the memory means are read out with a predetermined time relationship therebetween and the desired memory signals are combined to obtain an image signal, and an image is formed in accordance with the combined image signal.
Abstract:
A recording apparatus includes an image bearing member, image forming device for forming images on the image bearing member, a transfer medium, image transferring device for transferring the images from the image bearing member onto the transfer medium, a feeder for feeding the transfer medium to a transfer station, and control system for operatively controlling the transfer device and the feeder with mutually independently set delay times with respect to the start or the stop of operation of the image formation device.
Abstract:
A multiplexing electrostatic copier system employing one or more detachable, portable optical reader units, each including a "memory" or recorder, that may be readily carried about by a user for temporarily recording a "video" image of a printed document or other object to be copied or reproduced. For reproducing the recorded video image, the portable units are selectively connectable to an electrostatic copy making machine at the convenience of the users to transfer the remembered or recorded "video" images to the copy machine for reproducing the stored images and preparing a hard copy of the original document, e.g. a printed copy document on paper. The copier machine may also provide an advanced visual display of each of the transferred "video" images, enabling the users to initially observe the images before the hard copies are made.
Abstract:
A data recording system wherein output data from an electronic computer or the like to a display are re-edited in conformity with a predetermined recording system, and information is recorded in patterns of discrete dots developed by dot-forming means and in the feed direction of a recording paper therefor.
Abstract:
An electron beam type computer output on microfilm printer employing an electron beam writing apparatus having an evacuated housing closed by a Lenard window fabricated from a differentially etched bulk supporting member through which the electron beam is directed for permitting egress out of the evacuated housing into a higher pressure ambient atmosphere surrounding the housing with a minimum of beam scattering while maintaining the integrity of the evacuated space within the housing. The thin window portion consists of a material different than the bulk supporting member and not susceptible to the etchant employed to form the window in the supporting bulky member and may be formed by chemical reaction with the bulk supporting member from the class of materials consisting of SiSiO2; Al-Al2O3; Ta-TaO; Ti-TiO; Si-SiC; Si-SiN; Al2O3 on Si; and the like. The thin SiO2, Al2O3, TaO, TiO, etc window layer preferably first is formed to a desired thickness on the surface of a bulk supporting member by chemical reaction with the thin elongated window then being etched in the bulk supporting member by an etchant which does not react on the thin window layer. The electron beam type computer output on microfilm printer further includes an electron sensitive microfilm recording medium and transport means supporting the microfilm recording medium immediately adjacent the thin window portion of the electron beam recording apparatus. Printer control circuit means are coupled to the electron beam writing apparatus and the transport means for controlling the operation thereof. A character generator supplied from a buffer memory unit and controlled by the printer control circuit controls deflection and beam blanking of the electron beam recording apparatus. Use of the buffer memory allows the EBeam COM printer to be easily interfaced with any computer system as a standard plug compatible peripheral equipment.
Abstract:
An input typewriter-output printer system where characters originate from either a keyboard or computer and are encoded to binary form to be recognized by an AND gate circuit. The outputs of the AND gates are fed to a matrix generator that activates high-voltage gates to form characters. Each character is parallel fed along a fixed line that is in alignment with electrosensitive paper upon which the characters are printed by arcing through to a conducting platen divided into segments by insulators, each segment corresponding to one of the parallel characters on the fixed line. A binary up-down counter controlling the voltage to the segments sequentially completes the arcing circuit of the parallel characters through the paper.
Abstract:
The invention relates to a color image processing method and apparatus therefor, in which dot area ratio is decided when color printing is performed using inks of the four colors yellow, magenta, cyan and black.In color printing, in principle most colors can be printed by the superimposed printing of inks of the three colors Y, M, C.However, when performing color printing using four colors, inclusive of black, it is difficult to decide the dot area ratio of each color for the purpose of reproducing a target color, and excellent color reproduction cannot always be obtained even if printing is performed at the dot area ratios decided by the conventional method.Accordingly, the invention is adapted to decide area ratios A.sub.Y, A.sub.M, A.sub.C, A.sub.K of the Y, M, C, K inks, which accurately reproduce a target color X, Y, Z, by a method based upon biquadratic Neugebauer equations with four unknowns using tristimulus values of 16 types of color points obtained from actual measurement of the Y, M, C, K inks employed in actual printing.Excellent color reproduction can be achieved if color printing is carried out in accordance with each of the area ratios decided by the invention.
Abstract:
A print bar color printing system wherein exposure occurs through previously deposited color toner is compensated for light absorption in the previously deposited toner by selectively increasing the output of the print bar during a pixel time interval. Each time interval is divided into sublines which are available for applying image data. One subline transmits image data corresponding to the color of the image to be exposed at the photoreceptor surface, while the second subline carries information as to previously exposed and developed color images which overlap the subsequent image. The print bar is then selectively addressed to form the main color image with a pulse of relatively long duration, or duty cycle, followed by a pulse having a relatively short duty cycle. The second or third pulses represent the additional exposure level needed to compensate for light absorbed by previous color toners formed on the belt during the earlier development process.
