Description

MECANISME D'IMPRESSION THERMIQUE, NOTAMMENT APPLICABLE AUX TERMINAUX DE PAIEMENTTHERMAL PRINTING MECHANISM, ESPECIALLY APPLICABLE TO PAYMENT TERMINALS
L'invention est du domaine des machines à impression thermique. Elle a pour objet un mécanisme d'impression thermique notamment applicable aux terminaux de paiement. L'invention a plus particulièrement pour objet une structure de châssis participant de ce mécanisme. On connaît des mécanismes d'impression thermique, comprenant un châssis logeant principalement des moyens d'entraînement d'une bande à imprimer, une tête d'impression thermique, des moyens de mise en contact de la bande contre la tête d'impression, et des moyens électroniques de commande et de pilotage des organes dynamiques du mécanisme. Les moyens d'entraînement de la bande comprennent un moteur d'entraînement d'une réserve en rouleau de la bande. Celle-ci circule entre la tête d'impression et un rouleau d'appui, ce dernier étant entraîné en rotation par le moteur, par l'intermédiaire d'un train d'engrenage par exemple. Les moyens de mise en contact de la bande contre la tête d'impression comprennent couramment un organe élastique de poussée de la tête d'impression vers le rouleau d'appui.The invention is in the field of thermal printing machines. It relates to a thermal printing mechanism notably applicable to payment terminals. The invention more particularly relates to a chassis structure participating in this mechanism. Thermal printing mechanisms are known, comprising a chassis mainly housing means for driving a strip to be printed, a thermal printing head, means for bringing the strip into contact with the printing head, and electronic means for controlling and piloting the dynamic members of the mechanism. The strip drive means comprise a motor for driving a roll reserve of the strip. This circulates between the print head and a support roller, the latter being rotated by the motor, for example by means of a gear train. The means for bringing the strip into contact with the print head commonly comprise an elastic member for pushing the print head towards the support roller.
On notera à ce stade de la description qu'il est recherché pour ce type de mécanisme une structure simple, qui offre la possibilité de le rendre consommable, en vue de faciliter la maintenance des machines à imprimer auxquelles il est appliqué, terminaux de paiement notamment. Cette simplification de structure vise plus particulièrement à limiter les éléments qui le composent, et les opérations d'assemblage des différents organes entre eux. Cette simplicité de structure vise aussi essentiellement à rendre le mécanisme le plus compact possible, pour des raisons évidentes de gain d'encombrement.It will be noted at this stage of the description that a simple structure is sought for this type of mechanism, which offers the possibility of making it consumable, with a view to facilitating the maintenance of the printing machines to which it is applied, in particular payment terminals. . This structural simplification aims more particularly at limiting the elements which compose it, and the operations of assembling the various members together. This simplicity of structure also essentially aims to make the mechanism as compact as possible, for obvious reasons of gaining space.
On comprendra en cela que la présente invention s'inscrit dans ce cadre de contraintes, et des difficultés de conception qui en découlent.It will be understood in this that the present invention falls within this framework of constraints, and of the design difficulties which arise therefrom.
Il a été proposé par un art antérieur ancien des mécanismes d'impression essentiellement composés d'éléments métalliques, le châssis notamment. L'assemblage des éléments entre eux implique l'utilisation d'organes de fixation, avec pour conséquence un accroissement des opérations de montage, et un coût de production inopportunément élevé au regard du caractère compact et consommable recherché pour ce type de mécanisme. Il a donc été proposé par un art antérieur plus récent des châssis en matière plastique, permettant de répondre aisément à ces exigences, par une organisation du châssis pouvant être obtenue par moulage.It has been proposed by an old prior art printing mechanisms essentially composed of metallic elements, the chassis in particular. The assembly of the elements between them involves the use of fixing members, with the consequence of an increase in assembly operations, and an inexpensively high production cost in view of the compact and consumable character sought for this type of mechanism. It has therefore been proposed by a more recent prior art of plastic chassis, allowing these requirements to be easily met, by an organization of the chassis which can be obtained by molding.
Un problème posé par la réalisation d'un châssis en matière plastique réside dans sa fragilité. En effet, ce type de châssis comprend habituellement un couple de parois latérales entretoisées, qui supportent les organes fonctionnels du mécanisme. Cette fragilité résulte notamment d'une souplesse des parois latérales, qui altère leur maintien à distance constante l'une de l'autre. C'est pourquoi, il a été proposé en vue de rigidifier le châssis, de le doter d'une plaque de rigidification s'étendant sensiblement sur sa longueur. Cette plaque est rendue solidaire et immobilisée sur le châssis entre les parois latérales, tant en translation qu'en pivotement sur elle-même.A problem posed by the production of a plastic frame lies in its fragility. Indeed, this type of chassis usually comprises a couple of braced side walls, which support the functional members of the mechanism. This fragility results in particular from a flexibility of the side walls, which impairs their keeping at a constant distance from each other. This is why it has been proposed in order to stiffen the chassis, to provide it with a stiffening plate extending substantially over its length. This plate is made integral and immobilized on the chassis between the side walls, both in translation and in pivoting on itself.
On pourra notamment se reporter au brevet EP0969970 (APS ENGINEERING), qui décrit un tel mécanisme. On notera que selon cet art antérieur proche de celui de l'invention examinée, tant dans sa structure qu'au regard des problèmes généraux à résoudre, cette plaque de rigidification est avantageusement exploitée comme organe support des moyens électroniques de commande et de pilotage des organes dynamiques du mécanisme.Reference may in particular be made to patent EP0969970 (APS ENGINEERING), which describes such a mechanism. It will be noted that according to this prior art close to that of the invention examined, both in its structure and with regard to the general problems to be solved, this stiffening plate is advantageously used as a support member for the electronic means for controlling and piloting the organs dynamics of the mechanism.
Par ailleurs, un problème à résoudre pour les mécanismes à impression thermique, réside dans la dissipation de la chaleur générée par le moteur et dans la présence de charges électrostatiques inopportunes. Or, l'utilisation de châssis en matière plastique n'est guère adaptée à la résolution de ces problèmes, en impliquant des dispositions spécifiques pour y répondre, au détriment de la simplicité du mécanisme.Furthermore, a problem to be solved for thermal printing mechanisms lies in the dissipation of the heat generated by the motor and in the presence of untimely electrostatic charges. However, the use of plastic chassis is hardly adapted to the resolution of these problems, by implying specific provisions to respond to them, to the detriment of the simplicity of the mechanism.
Le but de la présente invention est de proposer un mécanisme d'impression thermique, et plus particulièrement une structure de châssis participant de ce mécanisme, qui offre un compromis satisfaisant entre des solutions apportées aux problèmes habituellement posés pour ces mécanismes et visés plus haut. L'invention vise notamment à proposer un tel mécanisme qui soit le plus compact possible, en étant d'une structure simple pour en réduire les coûts d'obtention, tant à la fabrication qu'au montage, robuste, et offrant des facultés de dissipation de chaleur et d'évacuation des charges électrostatiques qui soient optimisées. La présente invention propose plus particulièrement un châssis support des organes fonctionnels participant d'un tel mécanisme.The object of the present invention is to provide a thermal printing mechanism, and more particularly a chassis structure participating in this mechanism, which offers a satisfactory compromise between solutions to the problems usually posed for these mechanisms and referred to above. The invention aims in particular to propose such a mechanism which is as compact as possible, while being of a simple structure to reduce the costs of obtaining it, both during manufacture and during assembly, robust, and offering dissipation capabilities. optimized heat and evacuation of electrostatic charges. The present invention more particularly provides a support frame for the functional members participating in such a mechanism.
La démarche inventive de la présente invention a consisté dans un premier temps à réduire le volume de l'organe moteur, déterminant pour l'encombrement du mécanisme. A titre indicatif, cette réduction de l'organe moteur est obtenue par une réduction de son diamètre, pour ramener ce diamètre à une dimension de l'ordre comprise entre 15% à 20% de la largeur du mécanisme d'impression, plutôt que d'être de l'ordre de 25% de cette largeur telle qu'habituellement selon l'art antérieur. Se pose alors le problème de la chaleur générée par l'organe moteur, d'autant plus importante que son diamètre est réduit. La démarche inventive de la présente invention a consisté dans un second temps à exploiter la plaque de rigidification du châssis auquel elle est immobilisée, pour constituer un support du moteur sur laquelle il est fixé par l'intermédiaire de moyens caloporteurs. Ces moyens caloporteurs sont avantageusement des moyens simples de fixation par soudage. La plaque de rigidification, choisie métallique, constitue grâce à ces dispositions des moyens de dissipation de la chaleur générée par le moteur.The inventive step of the present invention consisted initially in reducing the volume of the motor member, determining for the size of the mechanism. As an indication, this reduction of the motor member is obtained by a reduction in its diameter, to reduce this diameter to a dimension of the order of between 15% to 20% of the width of the printing mechanism, rather than d '' be of the order of 25% of this width as usually according to the prior art. This raises the problem of the heat generated by the drive member, the more important the smaller its diameter. The inventive step of the present invention consisted, in a second step, in exploiting the stiffening plate of the chassis to which it is immobilized, to constitute a support for the engine on which it is fixed by means of heat transfer means. These heat transfer means are advantageously simple means of fixing by welding. The stiffening plate, chosen to be metallic, constitutes, by virtue of these provisions, means for dissipating the heat generated by the engine.
Il résulte de ces dispositions que l'encombrement général du mécanisme d'impression s'en trouve considérablement réduit par rapport à ceux de l'art antérieur, grâce à la réduction du diamètre du moteur et à sa fixation, par soudage notamment, sur la plaque de rigidification.It follows from these provisions that the overall size of the printing mechanism is considerably reduced compared to those of the prior art, thanks to the reduction in the diameter of the motor and to its fixing, in particular by welding, on the stiffening plate.
H résulte aussi de ces dispositions que cette réduction d'encombrement n'affecte pas les organes sensibles du mécanisme par un accroissement inopportun de la chaleur provoquée par le moteur, grâce à l'exploitation de la plaque de rigidification comme organe de dissipation de cette chaleur. Il en résulte en outre une simplification de structure du mécanisme, la plaque de rigidification pouvant être rapportée sur le châssis, par emboîtement notamment, postérieurement à sa liaison par soudage au moteur, avantageusement réalisée en atelier distant. Enfin, la plaque de rigidification étant exploitée comme organe de dissipation de la chaleur, ces dispositions permettent d'éviter de pourvoir le châssis d'éléments supplémentaires et spécifiquement destinés à cet effet.It also results from these provisions that this reduction in size does not affect the sensitive organs of the mechanism by an untimely increase in the heat caused by the motor, by virtue of the use of the stiffening plate as a body for dissipating this heat. . This also results in a simplification of the structure of the mechanism, the stiffening plate being able to be attached to the chassis, in particular by fitting, after its connection by welding to the engine, advantageously carried out in a remote workshop. Finally, the stiffening plate being used as a heat dissipation member, these provisions make it possible to avoid providing the chassis with additional elements and specifically intended for this purpose.
Par ailleurs, de telles dispositions permettent de simplifier la structure générale porteuse du mécanisme, châssis contreventé par la plaque notamment, en proposant une plaque de rigidification participante en elle- même de l'organe moteur, et plus particulièrement du corps cylindrique logeant ses organes fonctionnels. Plus précisément, la plaque de rigidification comporte une aile d'extrémité orientée transversalement à son extension générale, qui constitue une paroi de fermeture du corps cylindrique de l'organe moteur auquel elle est soudée.Furthermore, such provisions make it possible to simplify the general supporting structure of the mechanism, chassis braced by the plate in particular, by proposing a participating stiffening plate in itself of the motor member, and more particularly of the cylindrical body housing its functional organs. . More specifically, the stiffening plate comprises an end wing oriented transversely to its general extension, which constitutes a closure wall of the cylindrical body of the drive member to which it is welded.
Poursuivant la démarche inventive initiale de la présente invention, il est avantageusement proposé d'exploiter en outre la plaque de rigidification, en premier lieu pour constituer un support de l'organe élastique de poussée de la tête d'impression vers le rouleau d'appui. En deuxième lieu, les moyens électroniques de commande et de pilotage ne pouvant pas être supportés par la plaque de rigidification en raison de sa fonction dissipatrice de chaleur, celle-ci comporte de préférence en son travers une fenêtre longitudinale pour le passage d'un connecteur souple, participant des moyens électroniques de pilotage pour relier les organes dynamiques du mécanisme aux moyens électroniques de commande disposés à distance.Continuing the initial inventive step of the present invention, it is advantageously proposed to also use the stiffening plate, firstly to constitute a support for the elastic member for pushing the print head towards the support roller. . Secondly, since the electronic control and piloting means cannot be supported by the stiffening plate because of its heat dissipating function, the latter preferably has across it a longitudinal window for the passage of a connector. flexible, participating in electronic control means to connect the dynamic organs of the mechanism to electronic control means arranged remotely.
Plus précisément concernant les dispositions relatives à l'organe élastique, et selon un autre aspect de l'invention, celui-ci comprend au moins un ressort à lamelle pourvu de moyens de fixation sur la plaque de rigidification. Ces dispositions sont telles, qu'outre la simplification de structure du mécanisme obtenu, la poussée exercée sur la tête d'impression vers le rouleau d'appui est rendue homogène et fiable, le ressort à lamelle pouvant avantageusement s'étendre, de manière équivalente continue ou discontinue, sur la quasi-totalité de la largeur du mécanisme, pour prendre des appuis longitudinaux distants contre la tête d'impression.More specifically with regard to the arrangements relating to the elastic member, and according to another aspect of the invention, this comprises at least one leaf spring provided with fixing means on the stiffening plate. These provisions are such that, in addition to the simplification of the structure of the mechanism obtained, the thrust exerted on the printing head towards the support roller is made homogeneous and reliable, the leaf spring advantageously being able to extend, in an equivalent manner. continuous or discontinuous, over almost the entire width of the mechanism, to take distant longitudinal supports against the print head.
Les moyens de fixation du ressort à lamelle sur la plaque de rigidification sont avantageusement formés par des glissières latérales ménagées sur le ressort, à l'intérieur desquelles sont conjointement introduits les bords longitudinaux correspondant de la plaque de rigidification. Ces dispositions sont telles que le ressort à lamelle est relié à la plaque de rigidification par emboîtement coulissant. On relèvera aussi que la plaque de rigidification s'étend de préférence non seulement sur la longueur du châssis mais aussi sur sa largeur, pour d'une part offrir une assise idoine pour l'organe élastique de poussée de la tête d'impression vers le rouleau d'appui, et d'autre part favoriser la rigidification du châssis par un contreventement l'une à l'autre de ses parois latérales sur la majeure partie de sa profondeur.The means for fixing the leaf spring to the stiffening plate are advantageously formed by lateral slides formed on the spring, inside which are jointly introduced the corresponding longitudinal edges of the stiffening plate. These arrangements are such that the leaf spring is connected to the stiffening plate by sliding interlocking. It will also be noted that the stiffening plate preferably extends not only over the length of the chassis but also over its width, on the one hand offering a suitable seat for the elastic member for pushing the print head towards the support roller, and on the other hand promote the stiffening of the chassis by bracing one to the other of its side walls over most of its depth.
Par ailleurs, la liaison entre l'organe élastique et la plaque de rigidification est avantageusement exploitée en utilisant cet organe élastique comme moyen de verrouillage de l'immobilisation de la plaque de rigidification sur le châssis. Pour cela, l'organe élastique comporte un becquet élastique d'emboîtement coopérant avec un relief correspondant du châssis. Ces dispositions sont telles que la mise en place de la plaque de rigidification, porteuse de l'organe élastique, provoque un fléchissement du becquet à encontre de son maintien naturel jusqu'à son introduction contre le relief correspondant du châssis. Ce relief forme une butée à encontre du retour du becquet en position naturelle, de manière à faire obstacle au retrait spontané, voire volontaire, de la plaque de rigidification.Furthermore, the connection between the elastic member and the stiffening plate is advantageously exploited by using this elastic member as a means of locking the immobilization of the stiffening plate on the chassis. For this, the elastic member comprises an elastic interlocking spoiler cooperating with a corresponding relief of the chassis. These provisions are such that the establishment of the stiffening plate, carrying the elastic member, causes a deflection of the spoiler against its natural retention until its introduction against the corresponding relief of the chassis. This relief forms a stop against the return of the spoiler to the natural position, so as to prevent spontaneous, even voluntary, withdrawal of the stiffening plate.
Plus précisément encore et en relevant un autre aspect de l'invention, il est choisi un aménagement des moyens électroniques de pilotage comprenant le connecteur souple susvisé, qui s'étend à travers la fenêtre dont est pourvue la plaque de rigidification. Il en découle encore, non seulement une préservation des moyens électroniques de commande de la chaleur générée par le moteur, mais aussi un gain d'encombrement du mécanisme. Ce gain d'encombrement est plus particulièrement obtenu par l'éloignement des moyens électroniques de commande au-delà du mécanisme d'impression, sur le châssis de la machine à imprimer notamment.More precisely still and by raising another aspect of the invention, an arrangement of the electronic control means is chosen comprising the aforementioned flexible connector, which extends through the window with which the stiffening plate is provided. This also results, not only in preserving the electronic means for controlling the heat generated by the engine, but also in saving bulk in the mechanism. This gain in size is more particularly obtained by the distance of the electronic control means beyond the printing mechanism, on the chassis of the printing machine in particular.
L'utilisation d'un connecteur souple pour la transmission des informations de pilotage permet non seulement cet éloignement, mais aussi de libérer le volume intérieur du châssis, pour le rendre disponible pour la réception des autres organes du mécanisme et/ou pour réduire ce volume, avec pour résultat de réduire en conséquence l'encombrement global du mécanisme.The use of a flexible connector for the transmission of piloting information not only allows this distance, but also to release the interior volume of the chassis, to make it available for the reception of the other organs of the mechanism and / or to reduce this volume. , with the result of reducing accordingly the overall size of the mechanism.
Selon un autre aspect de la présente invention, le châssis est de préférence obtenu par moulage d'une matière plastique, simplifiant de ce fait sa réalisation, et comporte des reliefs pour la fixation par emboîtement, d'une part latéral de l'organe moteur et des extrémités du rouleau d'appui et de la tête d'impression, et d'autre part de la plaque de rigidification.According to another aspect of the present invention, the chassis is preferably obtained by molding a plastic material, thereby simplifying its production, and includes reliefs for fixing by interlocking, on a lateral part of the drive member. and of the ends of the support roller and of the print head, and on the other hand of the stiffening plate.
Grâce aux dispositions de l'invention, cette réalisation du châssis en une matière plastique ne fait néanmoins pas obstacle à un autre aspect de l'invention, qui réside dans une mise à la masse des organes du mécanisme susceptibles de véhiculer des charges électrostatiques. En effet, la tête d'impression comprend couramment un support de tête métallique sur lequel est déposé un substrat en céramique. Par ailleurs, le mécanisme est de préférence équipé d'un guide papier métallique, avantageusement formé par découpage-pliage d'une plaque en métal. Il en découle que l'ensemble des organes métalliques du mécanisme sont en contact électrostatique les uns en succession aux autres, notamment depuis le guide papier, la tête d'impression, le rouleau d'appui par l'intermédiaire du papier, l'organe élastique de poussée, la plaque de rigidification et l'organe moteur. Le connecteur souple, selon un autre aspect de son utilisation, est avantageusement mis à profit pour véhiculer ces charges électrostatiques vers un potentiel de référence, placé au-delà du mécanisme et notamment vers les moyens électroniques de commande supportés par la machine. On relèvera enfin que les dispositions qui viennent d'être décrites sont à prendre en considération, tant isolément qu'en combinaison, au regard des résultats obtenus afférents à chacune de ces dispositions ou à leur combinaison. La présente invention sera mieux comprise et des détails en relevant apparaîtront, à la description qui va en être faite d'une forme préférée de réalisation, en relation avec les figures des planches annexées, dans lesquelles :Thanks to the provisions of the invention, this embodiment of the chassis in a plastic material does not, however, preclude another aspect of the invention, which resides in the earthing of the members of the mechanism capable of carrying electrostatic charges. Indeed, the print head commonly comprises a metal head support on which is deposited a ceramic substrate. Furthermore, the mechanism is preferably equipped with a metallic paper guide, advantageously formed by cutting and folding a metal plate. It follows that all of the metal members of the mechanism are in electrostatic contact one after the other, in particular from the paper guide, the print head, the support roller through the paper, the member elastic thrust, the stiffening plate and the drive member. The flexible connector, according to another aspect of its use, is advantageously used to convey these electrostatic charges towards a reference potential, placed beyond the mechanism and in particular towards the electronic control means supported by the machine. Finally, it will be noted that the arrangements which have just been described are to be taken into consideration, both individually and in combination, with regard to the results obtained relating to each of these arrangements or to their combination. The present invention will be better understood and details will become apparent from the description which will be made of a preferred embodiment thereof, in relation to the figures of the appended plates, in which:
La fig.1 est une vue partielle éclatée d'un mécanisme d'impression thermique selon une forme préférée de réalisation de l'invention.Fig.1 is a partial exploded view of a thermal printing mechanism according to a preferred embodiment of the invention.
La fig.2 est une vue en perspective illustrant une plaque de rigidification supportant un moteur, qui participent du dispositif représenté sur la figure précédente. La fig.3 est une vue en perspective du mécanisme représenté sur la fιg.1.Fig.2 is a perspective view illustrating a stiffening plate supporting a motor, which participate in the device shown in the previous figure. Fig.3 is a perspective view of the mechanism shown in fιg.1.
La fig.4 est une vue partielle du mécanisme assemblé représenté sur la fig.1.Fig.4 is a partial view of the assembled mechanism shown in Fig.1.
La fιg.5 est une vue en perspective partiellement éclatée du mécanisme représenté sur la fιg.1.The fιg.5 is a partially exploded perspective view of the mechanism shown in the fιg.1.
Sur les figures, un mécanisme d'impression thermique comprend principalement : a) Un châssis 1 porteur des organes fonctionnels du mécanisme. b) Une tête d'impression thermique 4, particulièrement visible sur la fιg.5, c) Un rouleau d'appui 5 contre lequel est plaquée la bande à imprimer par l'intermédiaire de la tête d'impression 4. On relèvera que cette bande, dont la réserve en rouleau est supportée par une machine d'impression équipée du mécanisme de l'invention, n'est pas représentée sur les figures, d) Un moteur 6 d'entraînement de la bande à imprimer par l'intermédiaire du rouleau d'appui 5, qu'il entraîne en rotation par l'intermédiaire d'un train d'engrenage 7,7' ". On comprendra que le déplacement de la bande résulte de la rotation du rouleau d'appui 5 et de son pincement élastique entre ce dernier et la tête d'impression 4. e) Un connecteur souple 8 pour le pilotage des organes dynamiques du mécanisme, et notamment la mise en œuvre du moteur 6 d'entraînement du rouleau d'appui 5 et des moyens thermiques de la tête d'impression 4.In the figures, a thermal printing mechanism mainly comprises: a) A chassis 1 carrying the functional members of the mechanism. b) A thermal print head 4, particularly visible on fιg.5, c) A support roller 5 against which is pressed the strip to be printed via the print head 4. It will be noted that this strip, the roll reserve of which is supported by a printing machine equipped with the mechanism of the invention, is not shown in the figures, d) A motor 6 for driving the strip to be printed via the backing roller 5, which it drives in rotation by means of a gear train 7,7 '". It will be understood that the displacement of the strip results from the rotation of the support roller 5 and of its elastic nip between the latter and the print head 4. e) A flexible connector 8 for controlling the dynamic members of the mechanism, and in particular the implementation of the motor 6 of drive of the support roller 5 and thermal means of the print head 4.
Des reliefs sont prévus dans le châssis 1, par réserves au moulage, pour la fixation par emboîtement du moteur 6, du rouleau d'appui 5, de la tête d'impression 4 et d'une plaque 9 de rigidification. Cette dernière 9 s'étend sur la quasi-totalité des deux dimensions du châssis 1 , et supporte l'organe moteur 6.Reliefs are provided in the chassis 1, by molding reserves, for fixing by interlocking the motor 6, the support roller 5, the print head 4 and a stiffening plate 9. The latter 9 extends over almost all of the two dimensions of the chassis 1, and supports the motor member 6.
Un ressort à lamelle 10 est introduit par coulissement sur la plaque de rigidification 9, à laquelle il est fixé par emboîtement au moyen de glissières latérales 11 et 12 dont il est pourvu. Ces glissières coopèrent avec les bords longitudinaux extérieurs 13 et 14 de la plaque de rigidification 9. Ce ressort 10 est destiné à exercer une poussée élastique contre la tête d'impression 4, vers le rouleau d'appui 5 pour pincer entre eux la bande à imprimer. On remarquera aussi la présence d'un becquet élastique 2 permettant le verrouillage de l'immobilisation de la plaque de rigidification 9 sur le châssis 1. Ce becquet 2 coopère à cette fin avec un relief de butée ménagé sur le châssis lors de son moulage, non visible sur les figures.A leaf spring 10 is inserted by sliding onto the stiffening plate 9, to which it is fixed by interlocking by means of lateral slides 11 and 12 with which it is provided. These slides cooperate with the outer longitudinal edges 13 and 14 of the stiffening plate 9. This spring 10 is intended to exert an elastic thrust against the print head 4, towards the support roller 5 to pinch the web between them. to print. Note also the presence of an elastic spoiler 2 allowing the locking of the immobilization of the stiffening plate 9 on the chassis 1. This spoiler 2 cooperates for this purpose with an abutment relief formed on the chassis during its molding, not visible in the figures.
La plaque 9 de rigidification comporte enfin à son travers une fenêtre 15 pour le passage du connecteur souple 8.The stiffening plate 9 finally comprises through its window 15 for the passage of the flexible connector 8.
On relèvera enfin, sur la fιg.2 plus particulièrement, que la plaque 9 de rigidification comporte une aile 3 d'extrémité perpendiculaire à son extension générale. Cette aile 3 d'extrémité forme une paroi du corps cylindrique du moteur 6, auquel l'aile 3 est soudée. On remarquera que de façon avantageuse, la plaque de rigidification 9, et l'aile d'extrémité 3 qu'elle comporte, sont formées par découpage-pliage d'une plaque de métal. Finally, we note, on fιg.2 more particularly, that the stiffening plate 9 has an end wing 3 perpendicular to its general extension. This end wing 3 forms a wall of the cylindrical body of the motor 6, to which the wing 3 is welded. It will be noted that advantageously, the stiffening plate 9, and the end wing 3 which it comprises, are formed by cutting and bending a metal plate.
