Title
(EN) SERIAL PRINT WHEEL IMPACT PRINTER
(FR) IMPRIMANTE A IMPACT A ROUE D'IMPRESSION SERIELLE
Abstract
(EN)
Improved serial impact printer which both prints and serrates a document. The printer includes a print wheel (10) which is rotated to position a selected character in front of an anvil (12). The print wheel (10) includes a wheel-like circular member (28) having print characters (38) at the end of fingers (24) which extend from the top of the print wheel's perimeter. An impact mechanism (14) pressures the selected print character against the anvil (12), the document (16) being positioned between the selected print character (38) and impact mechanism (14). The impact mechanism (14) includes a controlled torque d.c. motor (40) which turns a threaded shaft (44) which is engaged with a threaded hole in the end of a hammer (50). Counterclockwise motion of the d.c. motor advances the hammer's head to pressure the back of the print character against the anvil (12), thereby printing and serrating the document with the selected character. Thereafter, clockwise motion of the d.c. motor (40) restores the impact mechanism (14) to its original position.

Imprimante à impact sérielle améliorée produisant des impressions en relief sur un document. L'imprimante comprend une roue d'impression (10) qui tourne pour positionner un caractère sélectionné en face d'une enclume (12). La roue d'impression (10) comprend un organe circulaire en forme de roue (28) possédant des caractères d'impression (38) à l'extrémité de doigts (24) s'étendant du sommet du périmètre de la roue d'impression. Un mécanisme à impact (14) comprime le caractère d'impression sélectionné contre l'enclume (12), le document (16) étant positionné entre le caractère d'impression sélectionné (38) et le mécanisme à impact (14). Ce dernier comprend un moteur à courant continu à commande de couple (40) qui fait tourner un arbre fileté (44) s'engageant dans un trou fileté à l'extrémité d'un marteau (50). Le mouvement dans le sens contraire à celui des aiguilles d'une montre du moteur à courant continu fait avancer la tête du marteau pour comprimer le dos du caractère d'impression contre l'enclume (12), imprimant ainsi en relief le caractère sélectionné sur le document. Successivement, le mouvement dans le sens des aiguilles d'une montre du moteur à courant continu (40) remet le mécanisme à impact (14) dans sa position originale.
