    摘要： An optical writing device (111) includes: a light source (250) including arrays (502) arranged in a main scanning direction, each array (502) including light-emitting elements arranged in the main scanning direction; a correction-value holding unit (222) to hold, correspondingly with a light-emitting element, a correction value for changing timing to read out pixel data stored in an image storage unit (210); and a light-source drive unit (221) to drive the light source (250) by reading out the stored pixel data stored, according to the correction value.
    The correction-value holding unit (222) includes a first area for holding a first correction value corresponding to a first light-emitting element located at an end of an array (502) and a second area for holding a second correction value corresponding to a second light-emitting element other than the first light-emitting element, the first holding area being larger than the second holding area.

    摘要： One aspect of this invention relates to an illumination device for an optical printer, the illumination device comprising: a first array of light sources (20) comprising a plurality of light source elements (14) that are each operable to emit light within a red band of the visible electromagnetic spectrum; a second array of light sources (21) comprising a plurality of light source elements (14) that are each operable to emit light within a blue band of the visible electromagnetic spectrum; and a third array of light sources (22) comprising a plurality of light source elements (14) that are each operable to emit light within a green band of the visible electromagnetic spectrum; wherein said first, second and third arrays of light sources (20, 21, 22) are generally linearly arranged along respective substantially parallel notional lines (34) on a substrate (15); and said plurality of light source elements (14) of each said array (20, 21, 22) are arranged such that respective adjacent light source elements of said plurality are offset from one another with respect to the associated notional line (34). Other aspects relate to printing heads, printing head assemblies, optical printers, and methods and apparatus for calibrating an optical printer.

    摘要： Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Verbesserung der Linearität von Elementen in einem Druckkopf durch Anwenden einer groben elektronischen Einstellung zur Neuanordnung des elektronischen Daten in der richtigen Pixellinie und anschließendes Anwenden einer feinen elektronischen Einstellung, um den Krümmungsfehler auf einen Bruchteil einer Pixellinie zu reduzieren. Die elektronische Feineinstellung nutzt Steuersignale zur Verzögerung der Belichtung, um die Linearität um einen Bruchteil einer Pixellinie zu korrigieren. Die Verzögerungen lassen sich wiederholen, um die Anzahl der verfügbaren Verzögerungen zu vervielfachen und die lineare Auflösung zu erhöhen

    摘要： At least one light emission array (7) includes a plurality of light emitting elements (Ea) arrayed in a first direction. Each of the light emitting elements (Ea) is an organic electroluminescence element. A controller (8) performs a constant voltage control with respect to the light emitting elements (Ea). A current detector (5) collectively detects a drive current flowing in each of the light emitting elements (Ea). A checker (3) checks light emitting characteristics of at least one of the light emitting elements (Ea) in accordance with the detected drive current.
