CA 2554372

A semiautomatic electronic printer comprises a housing (2) and, internally, a print head (8). A push-button (3), projecting upwards from the housing (2), is rigidly connected to a frame (7), which is mounted in a spring-charged relationship inside the housing (2) in such a manner to be vertically movable between a rest position and a working one. The frame (7) sustains in the upper part a printed circuit board including a microprocessor for acquiring from a separate computer data that have to be printed, and for storing such data, as well as for controlling the operation of the print head (8), supported by a carriage (20), with its inferior part being brought to touch the medium to be printed when the push-button is pushed downwards and to translate horizontally after the printing of a line of dots until a desired imaging made of a dot matrix has been printed on the all printing surface.

L'invention concerne une imprimante électronique semi-automatique comprenant un logement (2) et une tête d'impression (8) disposée à l'intérieur dudit logement. Un bouton-poussoir (3), faisant saillie vers le haut à partir du logement (2), est fixé rigide sur un cadre (7) monté à ressorts à l'intérieur du logement (2) de sorte à pouvoir se déplacer verticalement entre une position de repos et une position de fonctionnement. Le cadre (7) maintient la partie supérieure d'une carte de circuits imprimés contenant un microprocesseur permettant d'acquérir des données à imprimer provenant d'un ordinateur séparé, de stocker ces données, mais également de commander le fonctionnement de la tête d'impression (8) soutenue par un chariot (20), la partie inférieure de la tête d'impression étant mise en contact avec le support à imprimer lorsque le bouton-poussoir est enfoncé, la tête se translatant horizontalement après l'impression d'une ligne de points, jusqu'à ce qu'une image désirée constituée d'une matrice de points soit imprimée sur l'intégralité de la surface d'impression.
