Abstract: An optical scanning apparatus provides improved image quality by changing the amount of writing scale compensation for a pixel clock during a scanning cycle. A pixel clock generation unit of the optical scanning apparatus divides the scanning cycle into multiple division periods. A phase change of the pixel clock is carried out for each of the division periods. The phase change can also be different from scanning cycle to scanning cycle.

Abstract: An image forming apparatus is capable of controlling an exposure in accordance with sensitivity variations of a photosensitive body. An actual exposure position (Pr) sometimes precedes an exposure position (Pc) recognized based on the count value (C). In this case, the correction value (Dc) of the exposure position (Pc) recognized based on the count value (C) is calculated by linear interpolation using reference correction values (D0−Dn) corresponding to the position until the home position (HP) of a photosensitive drum is detected. When the home position (HP) is detected, the correction value (Dc(Pc0)) of an exposure position (Pc) recognized after detecting the home position (HP) is so calculated as to make the difference between the correction value of the exposure position and that of a previous exposure position (Pn′) fall within a preset range (α).

Abstract: An optical scanning device and method of optical scanning are provided. The optical scanning unit includes a resonant mirror controller scanning light emitted from a laser diode on a photoconductive drum, a first receive light sensor which receives the light scanned by the resonant mirror controller, and outputs a first horizontal synchronization signal which determines a start position of optical scanning according to the received light, and a video signal controller, responding to the first horizontal synchronization signal output from the first receive light sensor, controls the laser diode so that light corresponding to a video signal is emitted. In the optical scanning unit, a video signal controller can receive a plurality of horizontal synchronization signals (SOS; Start of Scan) through only one input pin irrespective of the number of receive light sensors which generate horizontal synchronization signals (SOS; Start Of Scan), which correspond to a start position of optical scanning.

Abstract: Measuring a feed spindle length change in a printing exposer, having at least one exposure head on a carrier moved axially along the drum in a feed direction by a stepping motor and the spindle, carries out the measurement by determining the number of stepping motor cycles needed by the carrier to travel through a reference section parallel to the feed direction. During calibration, an optimum number of cycles per revolution of the exposure drum is set, and the number of cycles needed to travel through the reference section is determined. During an operating phase, the number of cycles needed to travel through the reference section is determined and a corrected number of cycles per revolution of the exposure drum is determined in accordance with the relationship Kk=K0×Mx/M0. The temperature of the components involved in the measurement is kept constant with a temperature control system.

Abstract: In an image reading device having a sheet-through mechanism, a controller controls a stepping motor to decelerate an image reading system when the image reading system is moved to a reference white plate reading position, and controls a stepping motor drive electric current to decrease when the image reading system reads a reference white plate. When the image reading system finishes reading the reference white plate, the controller controls the stepping motor drive electric current to increase so as to rapidly decelerate the image reading system. The controller further controls the stepping motor such that a moving speed of the image reading system to an original document reading position is lower than a moving speed of the image reading system to the reference white plate reading position.

Abstract: Apparatus for and method of fully automatic rapid scanning and digitizing of an entire microscope sample, or a substantially large portion of a microscope sample, using a linear array detector synchronized with a positioning stage that is part of a computer controlled microscope slide scanner. The invention provides a method for composing the image strips obtained from successive scans of the sample into a single contiguous digital image. The invention also provides a method for statically displaying sub-regions of this large digital image at different magnifications, together with a reduced magnification macro-image of the entire sample. The invention further provides a method for dynamically displaying, with or without operator interaction, portions of the contiguous digital image. In one preferred embodiment of the invention, all elements of the scanner are part of a single-enclosure that has a primary connection to the Internet or to a local intranet. In this embodiment, the preferred sample type is a microscope slide and the illumination and imaging optics are consistent with transmission mode optics optimized for diffraction-limited digital imaging.
