CA 2094582

A recording apparatus includes a plurality of recording elements, a plurality of drive ICs, in which a plurality of drive signal lines containing a signal line for an image data signal and a signal line for a transfer clock which transfers the image data signal are connected in cascade. The drive IC supplies a recording current selectively to the recording elements in correspondence to the image data signal. A transfer clock control circuit, which is located at an input part of the transfer clock in the recording apparatus, controls a duty of the transfer clock supplied to the drive ICs so that a duty ratio of the transfer clock at the final stage of the plurality of drive ICs is enough to transfer the image data signal.

Appareil d'enregistrement comprenant un certain nombre d'éléments d'enregistrement et un certain nombre de CI d'attaque. Dans cet appareil sont connectées en cascade un certain nombre de lignes de signal d'attaque contenant un signal de données d'image et une ligne de signal d'une horloge de transfert qui transfère le signal de données d'image. Le CI d'attaque transmet sélectivement aux éléments d'enregistrement un courant d'enregistrement correspondant au signal de données d'image. Un circuit de commande d'horloge de transfert, situé à l'entrée de l'horloge de transfert dans l'appareil d'enregistrement, commande le facteur de forme des signaux d'horloge de transfert transmis aux CI d'attaque de sorte que ce facteur de forme, au niveau du dernier étage des circuits d'attaque, soit suffisant pour le transfert du signal de données d'image.
