Description

La présente invention a essentiellement pour objet une imprimante compacte présentant des dimensions réduites, notamment en ce qui concerne sa profondeur grâce à des dispositions particulières prises au niveau du cheminement du papier à l'intérieur de l'imprimante.The present invention essentially relates to a compact printer having reduced dimensions, in particular as regards its depth thanks to special arrangements made at the level of the routing of the paper inside the printer.

,Suivant le type d'alimentation en papier, il est possible de classer les imprimantes en plusieurs catégories :

  • - les imprimantes avec "Journal de fond",
  • - les imprimantes avec "Journal de fond" et insertion verticale,
  • - les imprimantes avec "Journal de fond" et insertion horizontale,
  • - et enfin les imprimantes avec insertion verticale seulement.
, Depending on the type of paper feed, printers can be classified into several categories:
  • - printers with "Background Journal",
  • - printers with "Background Journal" and vertical insertion,
  • - printers with "Background Journal" and horizontal insertion,
  • - and finally printers with vertical insertion only.

Une imprimante avec "Journal de fond" signifie que l'imprimante est approvisionnée en papier de façon continue depuis l'extérieur à partir d'un magasin d'alimentation contenant une charge de papier plié en zigzag par exemple. Le papier, entraîné à l'intérieur de l'imprimante par un système automatique d'entraînement et de guidage, passe devant une tête d'impression avant d'être évacué et stocké à l'extérieur dans un magasin de réception.A printer with "Background Journal" means that the printer is supplied with paper continuously from the outside from a feed store containing a load of zigzag folded paper for example. The paper, entrained inside the printer by an automatic drive and guide system, passes in front of a print head before being evacuated and stored outside in a reception store.

Une telle imprimante peut en plus être conçue pour faire de l'impression feuille par feuille, mais avec une insertion de papier différente de celle précédemment décrite. Cette insertion se fait soit suivant un plan vertical soit suivant un plan horizontal, justifiant ainsi les expressions précitées : imprimantes avec "Journal de fond" et insertion verticale, imprimantes avec "Journal de fond" et insertion horizontale.Such a printer can also be designed to do sheet-by-sheet printing, but with a different paper insertion than that previously described. This insertion is done either in a vertical plane or in a horizontal plane, thus justifying the above expressions: printers with "Background Journal" and vertical insertion, printers with "Background Journal" and horizontal insertion.

Dans le cas d'une insertion verticale, la feuille de papier est introduite par une ouverture située sur la face supérieure de l'imprimante et ressort, après impression, soit par cette même ouverture, soit par une ouverture prévue à la surface inférieure de l'imprimante. Entre l'introduction et l'évacuation de la feuille de papier, celle-ci reste toujours dans un même plan vertical.In the case of vertical insertion, the sheet of paper is introduced through an opening located on the upper face of the printer and exits, after printing, either through this same opening or through an opening provided on the lower surface of the printer. 'printer. Between the introduction and the evacuation of the sheet of paper, it always remains in the same vertical plane.

Dans le cas d'une insertion horizontale, les ouvertures précitées se trouvent au niveau des surfaces latérales de l'imprimante, et la feuille de papier reste toujours dans un même plan horizontal.In the case of horizontal insertion, the abovementioned openings are located at the side surfaces of the printer, and the sheet of paper always remains in the same horizontal plane.

Enfin, il existe des imprimantes sans "Journal de fond" mais avec seulement une insertion verticale du papier comme définie précédemment.Finally, there are printers without "Background Journal" but with only a vertical insertion of the paper as defined above.

Ces différentes imprimantes décrites succintement présentent un inconvénient majeur qui réside essentiellement dans le fait que ces imprimantes sont relativement encombrantes et nécessitent en plus des surfaces de dégagement indispensables à leur utilisation. Dans le cas d'une insertion horizontale ou verticale d'une feuille de papier, la profondeur ou la hauteur de l'imprimante doit au moins être égale à la longueur de la feuille si celle-ci est introduite et éjectée d'un même côté de l'imprimante. Bien entendu, cette hauteur ou profondeur peut être réduite si l'introduction et l'éjection de la feuille se font par deux ouvertures diamétralement opposées. Cependant, ce gain en dimension n'en est pas un puisqu'il faut prévoir une surface de dégagement pour la récupération du papier imprimé.These various printers described briefly have a major drawback which essentially resides in the fact that these printers are relatively bulky and also require clearance surfaces which are essential for their use. In the case of horizontal or vertical insertion of a sheet of paper, the depth or height of the printer must be at least equal to the length of the sheet if it is inserted and ejected from the same side of the printer. Of course, this height or depth can be reduced if the sheet is introduced and ejected by two diametrically opposite openings. However, this gain in size is not one since it is necessary to provide a clearance surface for recovering the printed paper.

L'invention vise à pallier ces inconvénients en proposant une imprimante compacte ne nécessitant plus des surfaces importantes de dégagement autour de l'imprimante tout en permettant de réduire ses dimensions.The invention aims to overcome these drawbacks by proposing a compact printer which no longer requires large clearance areas around the printer while allowing its dimensions to be reduced.

L'invention propose donc une imprimante compacte comprenant au moins : une tête d'impression ; une ouverture d'entrée pour l'insertion d'une feuille de papier à imprimer ; une ouverture de sortie pour l'évacuation de la feuille de papier après impression ; un système automatique d'entraînement et de guidage de la feuille de papier à l'intérieur de l'imprimante et définissant un chemin prédéterminé à suivre par la feuille de papier entre l'ouverture d'entrée et l'ouverture de sortie caractérisée en ce qu'elle comprend également des moyens pour recourber la feuille au fur et à mesure de son avance à l'intérieur de l'imprimante, ces moyens étant situés dans le chemin précité au-delà de la tête d'impression dans le sens d'entraînement de la feuille de papier, pour maintenir entièrement à l'intérieur de l'imprimante ladite feuille de papier tout au long de son impression.The invention therefore provides a compact printer comprising at least: a print head; an inlet opening for inserting a sheet of paper to be printed; an outlet opening for discharging the sheet of paper after printing; an automatic system for driving and guiding the sheet of paper inside the printer and defining a predetermined path to be followed by the sheet of paper between the inlet opening and the outlet opening characterized in that that it also includes means for bending the sheet as it advances inside the printer, these means being located in the aforementioned path beyond the print head in the direction of driving the sheet of paper, to keep entirely inside the printer said sheet of paper throughout its printing.

Avantageusement, l'insertion de la feuille de papier se fait dans un plan horizontal.Advantageously, the insertion of the sheet of paper is done in a horizontal plane.

Une telle imprimante présente donc un avantage important qui réside dans le fait qu'il est possible de la rendre plus compacte que tout autre imprimante connue pour une longueur de papier donnée. Une telle imprimante est donc d'une implantation facile et peut notamment être disposée en appui ou contre une paroi verticale.Such a printer therefore has an important advantage which lies in the fact that it is possible to make it more compact than any other known printer for a given length of paper. Such a printer is therefore easy to install and can in particular be placed in abutment or against a vertical wall.

D'autres caractéristiques, avantages et détails apparaitront plus clairement à l'aide de la description explicative qui va suivre faite en référence au dessin schématique annexé donné à titre d'exemple et qui illustre un mode de réalisation préférentiel de l'imprimante conforme à l'invention.Other characteristics, advantages and details will appear more clearly with the aid of the explanatory description which follows, made with reference to the appended schematic drawing given by way of example and which illustrates a preferred embodiment of the printer in accordance with the invention. 'invention.

En référence au dessin, l'imprimante (1) a tous ses éléments logés à l'intérieur d'un boitier ou carter (2). La surface latérale (2a), dénommée ci-après face avant, possède une ouverture d'entrée (3) telle qu'une fente horizontale. Dans ce mode de réalisation cette ouverture d'entrée (3) joue également le rôle d'ouverture de sortie.With reference to the drawing, the printer (1) has all of its elements housed inside a case or casing (2). The lateral surface (2a), hereinafter referred to as the front face, has an inlet opening (3) such as a horizontal slot. In this embodiment, this inlet opening (3) also plays the role of outlet opening.

Un système automatique (4) d'entraînement et de guidage de feuilles de papier (P) est monté à l'intérieur de l'imprimante (1) et a pour fonction d'entraîner et de guider chaque feuille de papier (P) à l'intérieur de l'imprimante (1) pendant son impression. Il est défini ainsi un chemin prédéterminé le long duquel se déplace chaque feuille de«-papier (P) à l'intérieur de l'imprimante (1).An automatic system (4) for driving and guiding sheets of paper (P) is mounted inside the printer (1) and has the function of driving and guiding each sheet of paper (P) to inside the printer (1) during printing. A predetermined path is thus defined along which each sheet of "-paper (P) moves inside the printer (1).

Le système (4) est par exemple constitué d'une surface porteuse horizontale (5) ou plateau d'insertion situé dans le prolongement de l'ouverture d'entrée (3). Pour faciliter l'insertion des feuilles de papier (P) dans l'imprimante (1), le plateau d'insertion (5) s'étend avantageusement de part et d'autre de l'ouverture d'entrée (3) comme représenté sur le dessin.The system (4) consists for example of a horizontal support surface (5) or insertion plate located in the extension of the inlet opening (3). To facilitate the insertion of the sheets of paper (P) into the printer (1), the insertion plate (5) advantageously extends on either side of the inlet opening (3) as shown on the drawing.

Le plateau d'insertion (5) est associé d'une part, à un dispositif d'entraînement (6) constitué par exemple de galets à friction (7) et d'autre part, à un dispositif de guidage latéral (non représenté) sur au moins un côté de la feuille de papier (P) à imprimer.The insertion plate (5) is associated on the one hand, with a drive device (6) consisting for example of friction rollers (7) and on the other hand, with a lateral guide device (not shown) on at least one side of the sheet of paper (P) to be printed.

Le dispositif d'entraînement (6) est par exemple un entraînement simple constitué de deux paires de galets à friction, chaque paire étant constituée de deux galets (7a, 7b) superposés et entre lesquels passe chaque feuille de papier (P) à imprimer. Les galets (7a, 7b) sont respectivement supportés par deux axes horizontaux (8a, 8b) disposés perpendiculairement par rapport au sens d'entraînement du papier, l'un des deux axes étant moteur. Les deux paires de galets (7a, 7b) sont respectivement situés vers les deux bords latéraux des feuilles de papier (P) à imprimer.The drive device (6) is for example a simple drive consisting of two pairs of friction rollers, each pair consisting of two rollers (7a, 7b) superimposed and between which passes each sheet of paper (P) to be printed. The rollers (7a, 7b) are respectively supported by two horizontal axes (8a, 8b) arranged perpendicularly to the direction of paper drive, one of the two axes being motor. The two pairs of rollers (7a, 7b) are respectively located towards the two lateral edges of the sheets of paper (P) to be printed.

Le dispositif d'entraînement (6) peut être un entraînement double avec, en plus des deux paires de galets (7a, 7b), deux autres paires de galets à friction (9a, 9b) supportés par deux axes (10a, 10b).The drive device (6) can be a double drive with, in addition to the two pairs of rollers (7a, 7b), two other pairs of friction rollers (9a, 9b) supported by two axes (10a, 10b).

La première paire de galets (7a, 7b) est positionnée vers l'extrémité du plateau d'insertion (5) située à l'intérieur de l'imprimante (1), alors que la deuxième paire de galets (9a, 9b) est positionnée entre l'ouverture d'entrée (3) et la première paire de galets (7a, 7b).The first pair of rollers (7a, 7b) is positioned towards the end of the insertion plate (5) located inside the printer (1), while the second pair of rollers (9a, 9b) is positioned between the inlet opening (3) and the first pair of rollers (7a, 7b).

A l'intérieur de l'imprimante (1) est également prévue une tête d'impression (12) positionnée entre les deux paires de galets (7a, 7b ; 9a, 9b).Inside the printer (1) is also provided a print head (12) positioned between the two pairs of rollers (7a, 7b; 9a, 9b).

Conformément à l'invention, chaque feuille de papier (P) est maintenue entièrement à l'intérieur de l'imprimante (1) tout au long de son impression. Pour cela il est prévu des moyens (13) formant guide pour recourber chaque feuille de papier (P) au fur et à mesure de son avance à l'intérieur de l'imprimante (1), ces moyens (13) étant situés dans le chemin précité au-delà de la première paire de galets (7a, 7b) dans le sens d'entraînement de la feuille (P).According to the invention, each sheet of paper (P) is kept entirely inside the printer (1) throughout its printing. For this, means (13) forming a guide are provided for bending each sheet of paper (P) as it advances inside the printer (1), these means (13) being located in the above-mentioned path beyond the first pair of rollers (7a, 7b) in the direction of the sheet feed (P).

Ces moyens (13) sont par exemple constitués par deux surfaces de guidage (13a), (13b) parallèles et recourbées entre lesquelles s'insère chaque feuille de papier (P). Ces deux surfaces constituent un guide ou un chemin de dégagement pour la feuille (P). Ainsi, la feuille de papier (P) à imprimer ne reste pas dans un même plan horizontal à l'intérieur de l'imprimante (1) tout au long de son impression. Bien évidemment la longueur du chemin de dégagement est fonction de la dimension maximale des feuilles de papier (P).These means (13) are for example constituted by two guide surfaces (13a), (13b) parallel and curved between which is inserted each sheet of paper (P). These two surfaces constitute a guide or a clearance path for the sheet (P). Thus, the sheet of paper (P) to be printed does not remain in the same horizontal plane inside the printer (1) all along of his impression. Obviously the length of the clearance path is a function of the maximum size of the sheets of paper (P).

Suivant un tel mode de réalisation, le sens d'entraînement de la feuille de papier (P) doit être inversé pour l'éjecter, une fois imprimée, par l'ouverture d'entrée (3) qui joue également le rôle d'ouverture de sortie. Dans ces conditions, la feuille de papier (P) n'est pas totalement dégagée dans le guide (13), le bout de la feuille ou bas de la feuille imprimé en dernier restant en prise avec les galets en friction (7a, 7b).According to such an embodiment, the direction of entrainment of the sheet of paper (P) must be reversed in order to eject it, once printed, through the inlet opening (3) which also plays the role of opening. Release. Under these conditions, the sheet of paper (P) is not completely exposed in the guide (13), the end of the sheet or bottom of the sheet printed last remaining in engagement with the rollers in friction (7a, 7b) .

Si l'on prolonge le guide (13), comme représenté en traits pointillés sur le dessin, jusqu'à le faire déboucher sur la face avant (2a) de l'imprimante (1) par une ouverture (14), cette ouverture peut alors jouer le rôle d'ouverture de sortie pour les feuilles de papier (P). Cela n'est possible que si la feuille de papier à imprimer a une longueur au moins égale à la longueur (L) du guide (13). Dans ce cas, il n'est pas nécessaire d'inverser le sens d'entraînement du papier pour assurer son éjection.If the guide (13) is extended, as shown in dotted lines in the drawing, until it opens onto the front face (2a) of the printer (1) through an opening (14), this opening can then play the role of exit opening for the sheets of paper (P). This is only possible if the sheet of paper to be printed has a length at least equal to the length (L) of the guide (13). In this case, it is not necessary to reverse the paper feed direction to ensure its ejection.

Dans ce dernier exemple, l'ouverture de sortie (14) est prévue au-dessus de l'ouverture d'entrée (3), mais à l'évidence elle pourrait être prévue au-dessous.In the latter example, the outlet opening (14) is provided above the inlet opening (3), but obviously it could be provided below.

Une telle imprimante n'impose qu'une seule surface de dégagement au niveau de sa face avant, ce qui facilite son implantation et son utilisation. Cet avantage est précieux, notamment dans l'utilisation de ce type d'imprimante dans des guichets par exemple.Such a printer imposes only one clearance surface at its front face, which facilitates its installation and its use. This advantage is precious, in particular in the use of this type of printer in counters for example.
