Abstract
(EN)
An image forming device 10 is provided with a control board 415 which outputs image data to a drive unit 303 in synchronism with a clock signal, a clock generating unit 422 which generates the clock signal, a synchronization signal generating unit 406 which generates a line synchronization signal for one line corresponding to the resolution, in a direction of rotation, of a photosensitive drum 102, and the control board 415, which controls the period of the clock signal and the period of the line synchronization signal in accordance with a magnification, in the direction of rotation of the photosensitive drum 102, of an image to be output, thereby enabling adjustment of the magnification in a sub-scanning direction to be performed accurately.

L'invention concerne un dispositif de formation d'image (10) qui est pourvu d'un tableau de commande (415) qui délivre en sortie des données d'image vers une unité de commande (303) de manière synchrone avec un signal d'horloge, d'une unité de génération d'horloge (422) qui génère le signal d'horloge, d'une unité de génération de signal de synchronisation (406) qui génère un signal de synchronisation de ligne pour une ligne correspondant à la résolution, dans une direction de rotation, d'un tambour photosensible (102), et du tableau de commande (415), qui commande la période du signal d'horloge et la période du signal de synchronisation de ligne conformément à un grossissement, dans la direction de rotation du tambour photosensible (102), d'une image devant être délivrée en sortie, ce qui permet ainsi d'ajuster de manière précise le grossissement dans une direction de sous-balayage.
