Abstract

Improvements to thermal printers of the "bar code" type characterised in that a bar is printed directly by means of a thermal matrix obtained, for example, by silk-screen printing. Application to weighing devices.

Description

La présente invention a pour objet un parfectionuement aux imprimantes thermiques pour dispositifs de pes@@@, machines à calculer cu analo@ues. Plus précisément l'invention @ @o@r objet un dispositif imprimant économique pour l'impression graphique du type "code-barre".The subject of the present invention is an improvement in thermal printers for weighing devices, machines for calculating analogicals. More precisely, the invention @ @ o @ r provides an economical printing device for graphic printing of the "barcode" type.

Actuellement de telles impressions sont effectuées au moyen de lignes de points thermiques, comportant, par exemple, trois ponts par millimétre, @ermettant la réalisation de graphismes, notamment de barres pour le codage dit "code-barre".Currently, such prints are made by means of lines of thermal dots, comprising, for example, three bridges per millimeter, allowing the production of graphics, in particular of bars for coding called "barcode".

Le principal inconvénient de ce systéme est @u'il faut un très grand nombre de points pour réaliser un graphisme @écessitant des commandes nombreuses entrainant un prix de revient relativement élevé et un rendement médiocre.The main drawback of this system is @ that a very large number of points is required to produce a graphics @ requiring numerous orders, resulting in a relatively high cost price and poor performance.

La présente invention à pour objet de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.

Elle consiste à imprimer directement un trait au moyen d'une matrice thermique qui pout être réalisée par sévigraphie d'encre résistive sur une plaquette en céramique ou en une matiére isolante (couche éraisse).Cette matrice peut émalement être réalisée per un dérôt métallique sur une plaquette de verre ou sur un surport émaillé (coucbe mince).On peut également réaliser un trait suivant la technique d'obtention des circuits imprimés; on peut aussi utiliser un fil résistif. It consists in directly printing a line by means of a thermal matrix which can be produced by screen printing of resistive ink on a ceramic plate or in an insulating material (thick layer). This matrix can also be produced by a metallic deposit on a glass plate or on an enamelled overlay (thin layer). One can also make a line according to the technique of obtaining printed circuits; you can also use a resistive wire.
