- et d'une seconde carte électronique à microprocesseur et à mémoire, contenant le programme de gestion simultanée desdites têtes.Still according to the main patent, a device for implementing this process essentially consists
- a mechanical assembly comprising the usual means of taking charge of the support and its advance, a first printing group consisting of a printing head and a printing cylinder situated on one side of the support and a second printing group identical to the first and located on the other side of the support,
a first electronic card carrying the means for controlling said mechanical assembly, by simultaneously controlling the advance of the support, the transverse displacements of the two printheads and the point-by-point printing of each of said heads,
- And a second electronic card with microprocessor and memory, containing the program for the simultaneous management of said heads.
Le présent Certificat d'Addition vise en premier lieu à décrire plus en détail la construction de ce dispositif et de ses divers organes, y compris certaines variantes, et notamment les moyens de détection du support et d'application dudit support contre le ou les rouleaux, ainsi que leur disposition. The purpose of this Addition Certificate is firstly to describe in more detail the construction of this device and of its various organs, including certain variants, and in particular the means of detecting the support and of applying said support against the roller (s) , as well as their arrangement.
Il vise en second lieu à préciser la structure du système électronique de commande dudit dispositif, notamment dans le cas de son association avec un ordinateur central unique. Secondly, it aims to specify the structure of the electronic control system for said device, especially in the case of its association with a single central computer.
Il vise enfin à spécifier les applications de ce dispositif, et les avantages que l'on peut en tirer, selon l'invention, par rapport à l'état de la technique. Finally, it aims to specify the applications of this device, and the advantages which can be drawn therefrom, according to the invention, compared with the state of the art.
Si l'on se réfère tout d'abord à la figure l du Brevet
Principal, on y retrouve les éléments de base du brevet principal, à savoir les têtes d'impression 3 et 4, coopérant avec les cylindres d'impression 5 et 6 pour imprimer un texte simultanément sur les deux faces d'un support 2.If we first refer to Figure l of the Patent
Main, there are the basic elements of the main patent, namely the printing heads 3 and 4, cooperating with the printing cylinders 5 and 6 to print a text simultaneously on the two faces of a support 2.
Selon le présent Certificat d'Addition, ces têtes 3 et 4 sont portées par des chariots, se déplaçant chacune sur une barre de support, et assurent l'impression sur le papier 2, par exemple par un système à aiguilles équipé d'un guide-fil, relié à une armature soumise aux actions d'un enroulement magnétique, contrôlé par un thermistor, l'extrémité de ce fil exerçant une pression surale papier à travers un ruban encreur. According to this Addition Certificate, these heads 3 and 4 are carried by carriages, each moving on a support bar, and ensure printing on the paper 2, for example by a needle system equipped with a guide. -wire, connected to an armature subjected to the actions of a magnetic winding, controlled by a thermistor, the end of this wire exerting paper pressure through an ink ribbon.
Le réglage de l'espace entre chaque tête et le cylindre correspondant se fait au moyen d'une vis de réglage modifiant selon sa position l'inclinaison d'une tige, et par suite celle de la tête 3 ou 4. The adjustment of the space between each head and the corresponding cylinder is made by means of an adjustment screw modifying according to its position the inclination of a rod, and consequently that of the head 3 or 4.
Un autre moyen de réglage est constitué par un levier, agissant sur une came de manière à déplacer parallèlement à son axe la barre de support. Another adjustment means is constituted by a lever, acting on a cam so as to move the support bar parallel to its axis.
il est bien entendu que, sur chacune des têtes d'impression, ces éléments sont connus, l'invention résidant dans le couplage de ces deux têtes connues. it is understood that, on each of the print heads, these elements are known, the invention residing in the coupling of these two known heads.
Ce couplage se fait par un système informatique dont les différents composants du système sont connectés à un ordinateur central CPU. This coupling is done by a computer system whose various components of the system are connected to a central computer CPU.
Diverses variantes des organes qui viennent d'être décrits peuvent être envisagées dans le cadre de l'invention. Various variants of the organs which have just been described can be envisaged in the context of the invention.
En premier lieu, il a été constaté que les presseurs de rouleau (non représentés, car usuels) peuvent avantageusement être remplacés par un système d'aspiration par des perforations pratiquées dans les cylindres 5 et 6, reliés eux-mêmes à une source de vide. Un tel système présente l'avantage de simplifier la construction de la machine, le papier suivant son chemin en se guidant lui-même. Firstly, it has been observed that the roller pressers (not shown, as usual) can advantageously be replaced by a suction system by perforations made in the cylinders 5 and 6, themselves connected to a source of vacuum. . Such a system has the advantage of simplifying the construction of the machine, the paper following its path by guiding itself.
Par ailleurs il est possible de réaliser des impression en plusieurs couleurs, en utilisant un ruban encreur à bandes multicolores, le passage d'une couleur à une autre en cours d'impression se faisant par déplacement vertical de la tête par rapport au ruban, ce déplacement étant lui-même contrôlé par le microprocesseur, au même titre que les autres fonctions de la tête. Furthermore, it is possible to carry out printing in several colors, using an ink ribbon with multicolored bands, the passage from one color to another during printing being done by vertical displacement of the head relative to the ribbon, this displacement being itself controlled by the microprocessor, in the same way as the other functions of the head.
Enfin, il est prévu, selon l'invention, d'utiliser un cylindre d'impression unique au lieu des deux cylindres 5 et 6, auquel cas ce cylindre pourrait avoir un diamètre inférieur, et les deux têtes d'impression 3 et 4 sont face à face. Finally, it is planned, according to the invention, to use a single printing cylinder instead of the two cylinders 5 and 6, in which case this cylinder could have a smaller diameter, and the two printing heads 3 and 4 are face to face.
En ce qui concerne les moyens de détection du papier, identifiés au brevet principal comme étant des cellules photo-électriques 7, peuvent avantageusement être remplacés par des palpeurs mécaniques, qui déterminent alors le type de presseur (latéraux pour la largeur correspondant aux bandes dites Caroll, et centraux pour la largeur standard). Regarding the paper detection means, identified in the main patent as being photocells 7, can advantageously be replaced by mechanical feelers, which then determine the type of presser (lateral for the width corresponding to the so-called Caroll strips , and central for the standard width).
Les applications du dispositif selon l'invention sont pratiquement illimitées, dans tous les domaines où l'impression recto-verso ne se fait actuellement que par retournement du support après un premier passage davant la tete d'impression, puis par un second passage devant la même tête. Il est possible, par exemple, d'imprimer simultanément un texte au recto d'un support et des illustrations photographiques au verso. Dans ce cas l'illustration à imprimer est reprise par une caméra, digitalisée, et stockée en mémoire au même titre qu'un texte. The applications of the device according to the invention are practically unlimited, in all the fields where two-sided printing is currently done only by inverting the support after a first pass before the print head, then by a second pass in front of the same head. It is possible, for example, to simultaneously print a text on the front of a support and photographic illustrations on the back. In this case, the illustration to be printed is taken up by a camera, digitized, and stored in memory in the same way as text.
Parmi d'autres applications possibles, on peut citer l'impression transversale de documents à lecture verticale (ou vice-versa), ou la re-composition de documents pour les éditer sous des dimensions différentes, par exemple en vue d'obtenir un formulaire de 4 pages en un seul passage dans la machine, puis pliage. Une application particulièrement importante est celle de l'édition de formulaires administratifs. Among other possible applications, we can cite the transverse printing of documents with vertical reading (or vice versa), or the re-composition of documents to edit them in different dimensions, for example in order to obtain a form of 4 pages in a single pass in the machine, then folding. A particularly important application is that of the edition of administrative forms.
Il est bien entendu que la simultanéité d'impression des deux faces du support est indépendante du contenu à imprimer sur chaque face, la détection de la fin d'une page déterminant seule le passage à la page suivante. De même il est possible de limiter l'impression à l'une seulement des deux faces, en inhibant l'autre. De même encore, il est possible d'utiliser un microprocesseur pour chaque tête, ou un seul pour l'ensemble des deux, selon sa capacité. It is understood that the simultaneous printing of the two sides of the support is independent of the content to be printed on each side, the detection of the end of a page alone determining the passage to the next page. Likewise, it is possible to limit printing to only one of the two faces, by inhibiting the other. Similarly, it is possible to use a microprocessor for each head, or only one for all two, depending on its capacity.
Dans le cas de la connection à un ordinateur central, quelle que soit sa nature, il suffit, pour faire fonctionner le système selon l'invention, d'adjoindre aux codes utilisés par les logiciels existants des "routines" simples, à savoir
Escape Escape r pour l'impression recto seule
Escape Escape v pour l'impression verso seule
Escape Escape s pour l'impression recto-verso simultanée.In the case of connection to a central computer, whatever its nature, it suffices, to operate the system according to the invention, to add to the codes used by existing software simple "routines", namely
Escape Escape r for single sided printing
Escape Escape v for back only printing
Escape Escape s for simultaneous two-sided printing.
La souplesse d'utilisation du système selon l'invention et sa simplicité de construction en font un progrès énorme et incontestable qui en garantissent le caractère de brevetabilité. The flexibility of use of the system according to the invention and its simplicity of construction make it an enormous and indisputable progress which guarantees its patentability.
