Abstract
Description
L'invention concerne les imprimantes thermiques, et aussi bien les imprimantes en tant que telles, périphériques d'autres équipements, que les appareils à imprimante intégrée, comme par exemple les télécopieurs.The invention relates to thermal printers, and both printers as such, peripherals of other equipment, that devices with integrated printer, such as fax machines.
Plus particulièrement, l'invention concerne les imprimantes thermiques dans lesquelles une tête d'impression thermique, à éléments résistifs chauffants, est disposée pour imprimer, sur un support a priori en papier, des pages d'un document, à recevoir d'un correspondant s'il s'agit d'un télécopieur. Il existe principalement deux types d'imprimantes thermiques.More particularly, the invention relates to thermal printers in which a thermal print head with resistive elements heated, is arranged to print, on a support a priori in paper, pages of a document, to be received from a correspondent if it is a fax machine. There are mainly two types of printers thermal.
Dans celles du premier type, actuellement les plus répandues, le support est un papier spécial dit thermique, utilisé en rouleau.In those of the first type, currently the most widespread, the support is a special thermal paper, used in roll.
Dans les imprimantes du deuxième type, qui commencent à apparaítre sur le marché, le support est papier ordinaire, utilisé alors en feuilles et en ramette, mais qui nécessite un ruban d'impression spécial, utilisé en rouleau. Il s'agit, plus précisément, d'un ruban revêtu d'une couche d'encre thermo-fusible qui, lors de l'impression, par activation des éléments chauffants de la tête, est transférées sur une feuille du papier. On parle alors d'une impression par transfert thermique.In printers of the second type, which are beginning to appear on the market, the support is plain paper, then used in sheets and in reams, but which requires a special printing ribbon, used in roller. More specifically, it is a ribbon coated with a layer hot-melt ink which, when printed, by activating the heating elements from the head, is transferred to a sheet of paper. This is called thermal transfer printing.
Avec les premières imprimantes, il existe le risque que le rouleau de papier thermique ne se termine prématurément ou inopinément.With the first printers, there is a risk that the roll of thermal paper does not end prematurely or unexpectedly.
Avec les secondes imprimantes, il existe aussi le risque que le rouleau encreur ne se termine prématurément ou inopinément.With second printers, there is also the risk that the roller ink does not end prematurely or unexpectedly.
JP-59 059470 enseigne une imprimante pouvant imprimer des feuilles de papier ordinaire, provenant d'un bac, au moyen d'un ruban à transfert thermique ou bien du papier thermo-sensible en rouleau, se substituant au ruban et reçu dans le logement de celui-ci pour limiter le volume de l'imprimante. De ce fait, l'imprimante est limitée à l'utilisation de rouleaux de papier thermique de taille très limitée, s'épuisant rapidement. JP-59 059470 teaches a printer that can print sheets of plain paper from a tray using transfer ribbon or heat-sensitive roll paper, replacing tape and received in the housing thereof to limit the volume of the printer. As a result, the printer is limited to the use of rollers thermal paper of very limited size, quickly depleting.
La présente invention vise à supprimer cette limitation.The present invention aims to remove this limitation.
A cet effet, l'invention concerne une imprimante thermique comprenant une tête d'impression thermique, des moyens d'entraínement d'un support papier devant la tête d'impression, des moyens d'introduction de feuilles de papier, des moyens d'extraction des feuilles de papier, des moyens pour entraíner un ruban d'impression par transfert thermique devant la tête d'impression, l'imprimante étant agencée pour recevoir un rouleau de papier et les moyens d'extraction étant agencés pour dérouler le rouleau de papier, caractérisée par le fait qu'elle comporte des moyens agencés pour recevoir un moyeu de rouleau, montés mobiles d'une position d'impression par transfert thermique et de support d'un rouleau de ruban encreur à une position d'impression directe et de support d'un rouleau de papier thermique.To this end, the invention relates to a thermal printer comprising a thermal print head, means for driving a paper support in front of the print head, means for introducing sheets of paper, means of extracting sheets of paper, means for driving a thermal transfer printing ribbon in front of the print head, the printer being arranged to receive a paper roll and the extraction means being arranged to unwind the paper roll, characterized in that it includes means arranged to receive a roller hub, movably mounted with a roll transfer and roll support position ink ribbon at a direct printing position and support a thermal paper roll.
La position des moyens de réception d'un moyeu de rouleau étant variable, on peut ainsi choisir la position de réception du rouleau de papier thermique pour qu'elle permette de recevoir un rouleau de diamètre relativement important.The position of the receiving means of a roller hub being variable, you can choose the receiving position of the thermal paper so that it can receive a roll of relatively large diameter.
Les moyens d'entraínement du support papier, en feuilles ou en rouleau, comprennent généralement un rouleau d'appui. Les moyens d'introduction des feuilles de papier sont prévus dans l'imprimante de l'invention mais peuvent naturellement ne pas être utilisés en cas d'un support papier en rouleau.The means for driving the paper support, in sheets or in rolls, usually include a backing roller. Ways paper sheets are provided in the printer the invention but can naturally not be used in the event of a roll paper support.
L'imprimante est agencée pour recevoir un rouleau de papier, thermique, mais pareil agencement peut ne pas être utilisé non plus.The printer is arranged to receive a roll of paper, thermal, but such an arrangement may not be used either.
L'invention sera mieux comprise à l'aide de la description suivante de quatre formes de réalisation préférées de l'imprimante de l'invention, en référence au dessin annexé, sur lequel :
- la figure 1 est une vue latérale schématique de la première forme de réalisation préférée de l'imprimante de l'invention, utilisant un ruban encreur d'impression à transfert thermique,

L'imprimante représentée sur la figure 1 appartient à un
télécopieur et comporte une tête d'impression thermique 1 et un
rouleau d'appui 2 disposé en regard.The printer shown in Figure 1 belongs to a
fax machine and has a thermal print head 1 and a
Pour la concision de l'exposé, on notera que tous les axes des figures s'étendent perpendiculairement au plan des figures.For the sake of brevity, it will be noted that all the axes of the figures extend perpendicular to the plane of the figures.
Un capot 3 de l'imprimante supporte un magasin d'entrée 4,
associé à un rouleau d'introduction 4A, prévu pour recevoir une
ramette de feuilles de papier 20 à imprimer, tandis que deux galets
d'extraction 5 assurent l'extraction des feuilles de papier 20, qui
sortent par une fente 3A du capot 3. Deux goulottes 6 et 7 sont
agencées pour guider le papier 20, respectivement entrant et
sortant, du magasin 4 vers la tête 1 et le rouleau 2, en passant
entre eux deux, et de la tête 1 vers les galets d'extraction 5 et la
fente 3A.A
Un logement 11 de l'imprimante comporte ici un axe fixe 12 portant
un rouleau débiteur 13 de ruban d'impression thermique 14, tandis
qu'un logement 15 comporte un axe d'entraínement 16 portant un
rouleau récepteur 17 de ruban 14 usagé et couplé en rotation avec
lui. Le ruban 14 passe du rouleau débiteur 13 au rouleau récepteur
17 en étant plaqué contre la tête 1, entre celle-ci et le rouleau
d'appui 2. Le rouleau d'appui 2 est entraíné en rotation par un
engrenage non représenté commun aux galets d'extraction 5 et
assure aussi, par friction, l'entraínement du papier 20 et du ruban
14.A housing 11 of the printer here comprises a
Un moteur d'entraínement 18 entraíne en rotation l'axe 16 et
dévide le ruban 2 contre l'action d'un galet de guidage 19 disposé
en sortie du logement 11.A
Il est aussi prévu, dans cet exemple, un détecteur 21 de présence
du rouleau 13 débiteur de ruban 14.In this example, a presence detector 21 is also provided.
of the ribbon-
La même imprimante est représentée sur la figure 2, mais y est
équipée d'un réceptacle amovible 23 agencé pour recevoir un
rouleau 33 de papier thermo-sensible 34, ici porté par un axe ou
moyeu 32. Le réceptacle 23 est fixé de façon amovible, non
illustrée, par clipsage sur le capot 3, et comporte une goulotte 24
de guidage pour amener le papier thermo-sensible 34 jusqu'à la
tête d'impression 1. Le capot 3 présente ici une surface externe 25
de forme cylindrique circulaire localement concave complétant
celle du réceptacle 23 pour enrober le papier 33.The same printer is shown in Figure 2, but is there
equipped with a
Un détecteur 22 est disposé pour détecter la présence du rouleau
de papier 33. Les détecteurs 21 et 22 servent à améliorer la
commande du guidage du papier thermique 33 en sortie et à régler
la commande de la tête d'impression 1 en fonction du type
d'impression, par ruban ou avec du papier thermo-sensible.A
Le deuxième exemple représenté sur la figure 3 est l'homologue de
celui de la figure 1 et l'imprimante, toujours d'un télécopieur,
utilise un rouleau 113 du ruban thermo-sensible 114 consommable.
Les éléments des figures 3 et 4 semblables à ceux des figures 1 et
2 y portent la même référence, précédée de la centaine 1 et de la
dizaine 1 le cas échéant. De ce fait, ils ne sont pas à nouveau
décrits. The second example shown in Figure 3 is the counterpart of
that of Figure 1 and the printer, still a fax machine,
uses a
Sur la figure 4, homologue de la figure 2, l'imprimante fonctionne
avec un rouleau 133 de papier thermique 134. Le capot 103
comporte une ouverture 140 bordée par deux volets rotatifs 141 et
142 s'ouvrant vers l'extérieur pour recevoir le rouleau 133 de
papier thermique 134. Un volet 143 à glissière est monté glissant
sur le volet 141 pour, en position déployée, rejoindre le bord
externe du volet 142 et ainsi fermer le logement 123 du rouleau de
papier 133.In figure 4, homologous to figure 2, the printer works
with a
Une paire de biellettes, dont une seule, 135, est représentée, sont
montées rotatives à une extrémité autour d'un axe 136 voisin du
raccordement du volet 142 avec le capot 103, et elles comportent
respectivement, à des extrémités opposées, deux paliers 137
autour desquels sont respectivement montées rotatives une paire
d'autres biellettes, dont l'une, 138, est représentée. Les biellettes
135 et 138 sont distantes axialement pour encadrer le rouleau 133
par ses flancs. Les paliers 137 sont prévus pour recevoir le moyeu
132 du rouleau 133. Les biellettes 138 assurent un maintien latéral
du papier du rouleau 133 et, dans cet exemple, assurent aussi son
freinage.A pair of rods, of which only one, 135, is shown, are
rotatably mounted at one end around an
Comme le montre la figure 3, les volets 141-143 occupent au repos
une position repliée, pour laquelle ils sont superposés et ferment
le capot 103, tandis que les biellettes 135 et 138 sont repliées à
l'intérieur du capot 103.As shown in Figure 3, flaps 141-143 occupy at rest
a folded position, for which they are stacked and close
the
Ainsi, les biellettes 135 et 138, agencées pour recevoir le moyeu
132 du rouleau 133, sont montées mobiles d'une position
d'impression par transfert thermique et de support du rouleau 113
de ruban encreur à une position d'impression directe et de support
du rouleau 133 de papier thermique. Pour leur part, les volets 141-143
sont mobiles entre une position de fermeture et une position
d'ouverture et de réception du rouleau 133 de papier thermique. Thus, the
Les éléments des imprimantes des troisième et quatrième formes de réalisation, représentées sur les figures 5 et 6, homologues de ceux des figures précédentes portent les mêmes références, avec respectivement une centaine 2 et 3.Elements of printers of third and fourth forms of embodiment, represented in FIGS. 5 and 6, counterparts of those of the preceding figures bear the same references, with one hundred and two respectively.
