Abstract:
This invention makes it possible to prevent any uneven density and degradation in resolution in reciprocal laser scanning using a movable mirror. An image forming apparatus forms an image on a photosensitive member by scanning the photosensitive member with a laser beam reflected by a movable mirror with reciprocating the movable mirror whose rotation angle is changeable in accordance with an electrical signal. The apparatus detects the rotation direction of the movable mirror, and weights, on the basis of the rotation direction, image data of two lines along the sub-scanning direction in correspondence with the ratio of the scanning length after the start of laser write for a line of laser scanning to compensate the image to be formed using the movable mirror.
Abstract:
An image-recording apparatus 1 includes image recording assembly 60 and a control section 40 having image-processing section 44 . The image-processing section divides the image data indicative of the complete image into a plurality of image data pieces indicative of divided images, detects two adjoining divided-images that individually have a joint portion and adjoin each other at the respective joint portions, in the divided images indicated by the divided image data pieces and rotates one of the adjoining divided-images so as to make a recording direction of one of the adjoining divided-images opposite to a recording direction of the other adjoining divided-image. The control section controls the image recording assembly so that a recording medium carries in one direction during recording all divided-images. The divided images are recorded on the respective recording-media one by one to form a plurality of output images. The plurality of output images configure one complete image.

Abstract:
Bei einem Verfahren zum Erfassen und Bedrucken von papiernen Dokumenten wird das Dokument nach dem Einführen beziehungsweise Einlegen in eine kombinierte Drucker/Scanner-Einrichtung in einem ersten Schritt gescannt und abgespeichert, in einem zweiten Schritt mit einer Zusatzinformation bedruckt und in einem darauffolgenden dritten Schritt nochmals gescannt und abgespeichert, wobei das Dokument in den einzelnen Schritten dieselbe Transportbahn durchläuft. Mittels dieses Verfahrens ist eine Vereinfachung der Ver- und Bearbeitung von zu ergänzender Dokumente und deren speichernden Erfassung in den beiden unterschiedlichen Zuständen in einfacher Weise ermöglicht.
Abstract:
A disclosed optical scanning device includes a light beam generating unit configured to generate a light beam; a light beam deflecting unit configured to receive the light beam and deflect/emit the light beam with a deflecting mirror; a light beam ON/OFF control unit configured to control the light beam generating unit so that the light beam deflected by the light beam deflecting unit is turned ON/OFF in a particular light beam scanning region while the light beam is being reciprocally scanned; and a light beam scanning time measuring unit configured to obtain a measurement value by measuring a time at which the light beam passes a reference point provided on an edge part of the entire light beam scanning region that is away from a center part of the entire light beam scanning region. Timings at which the light beam is turned ON/OFF are controlled in accordance with the measurement value.
Abstract:
A system for scanning an imaging plate (10), comprising: a continuous belt drive (16); a first scanning head (12) mounted to the drive belt (16); a second scanning head (14) mounted to the belt drive (16); and a laser (20) positioned to direct a laser beam (21) in a beam path across the imaging plate (10), wherein the continuous belt drive (16) is positioned to sequentially move each of the first and second heads (12, 14) in a path collinear with the laser beam path when moving across the imaging plane (10).
Abstract:
A system for scanning an imaging plate (10), including a continuous belt drive(36), a drive assembly (40) connected to the continuous belt drive (36), a scanning head (35) connected to the drive assembly (40), and a laser (50) positioned to direct a laser beam (51) in a beam path across the surface of the imaging plate (10), wherein the drive assembly (40) is adapted to move the scanning head (35) back and forth in a path which is collinear with the beam path as the continuous belt drive (36) is rotated in one direction.
