Definitions
- the present invention relates to a printer thermal intended to be associated with any terminal an information processing facility.
- the terminal is equipped with a video screen of the like television receiver, minitel or installation monitor IT ... with which it is necessary to associate a printer for example for printing data appearing on this video screen and more particularly when it comes to fugitive data which disappear by the very fact of using the terminal by an operator.
- a very specific application of this type installation is interactive television by which transactions are negotiated.
- a printer whose power supply is connectable directly at the terminal, whatever the characteristics of his diet, and despite the fact that in general this power supply is sized only for the needs of the terminal. There is no longer any need to connect the printer to the energy distribution network which simplifies the hardware by removing a connection socket from the printer to the distribution network and removing the constraint for the user to provide a place specific for this connection.
- the invention therefore relates to the combination a terminal and a printer of a treatment plant data comprising on the one hand, a terminal comprising its electric power supply sized to its specific need and a multi-pin outlet having at least two pins for the transmission of data and two other pins between which is has a supply voltage derived from said specific power supply and secondly, a printer whose power supply is provided by a battery rechargeable battery, the system comprising a electric connection for charging the rechargeable battery, connected to output pins with voltage derived from the terminal's specific power supply.
- the terminal in question is represented on the figure in the form of a television set 1, comprising a power cord 2, link 3 with a unit central or a network not shown, and a cable link 4 intended to be connected to a printer 5.
- the power to the thermal printer is as for it ensured by a connected rechargeable battery to the power supply of terminal 1 by means of the cable connection 4.
- the outlet 7 at the rear of terminal 4 is generally multispindle. Between two of his pins there is a supply voltage derived from specific terminal power supply. In the same way the input socket 8 of the printer 5 includes these same pins so that cable 4 connects the rechargeable battery to supply terminal 1.
- the link 4 is of the type RS 485 6-wire with RJ11 socket, two wires not being connected, two used for data transmission and two used for power supply, for example 9V.
- This storage battery 6 is therefore recharged by low currents diverted from the terminal 1 supply which, although dimensioned to the specific needs of this terminal, authorizes this parallel connection of a rechargeable battery.
- printer 5 In this type of application, the use of printer 5 is sporadic, so the time during which the battery is used to supply energy to the printer is very much less than the time during which the weak current from the supply of the terminal 1 charges this battery. Furthermore, when printer 5 uses the energy source, it is usually from strong currents for brief periods time intervals. The power supply of terminal 1 cannot not deliver energy in this form. However, the rechargeable battery 6 is able to fit perfectly the printer's energy requirements 5.
- the main advantage of the invention is to simplify connections between a terminal and a printer appendix intended to constitute a written proof of the data carried or transiting through this installation terminal data processing.

Description
La présente invention concerne une imprimante thermique destinée à être associée à un terminal quelconque d'une installation de traitement de l'information.The present invention relates to a printer thermal intended to be associated with any terminal an information processing facility.
Pour illustrer une application de l'invention on supposera que le terminal est équipé d'un écran vidéo du genre récepteur de télévision, minitel ou moniteur d'installation informatique... auquel il est nécessaire d'associer une imprimante pour par exemple réaliser l'impression des données figurant sur cet écran vidéo et plus particulièrement lorsqu'il s'agit de données fugitives qui disparaissent du fait même de l'utilisation du terminal par un opérateur. Une application toute particulière de ce type d'installation est la télévision interactive par laquelle des transactions se négocient.To illustrate an application of the invention, will assume that the terminal is equipped with a video screen of the like television receiver, minitel or installation monitor IT ... with which it is necessary to associate a printer for example for printing data appearing on this video screen and more particularly when it comes to fugitive data which disappear by the very fact of using the terminal by an operator. A very specific application of this type installation is interactive television by which transactions are negotiated.
L'association d'une imprimante et d'un terminal d'une installation de traitement de l'information est connue en elle-même. En général, le terminal dispose d'une alimentation qui lui est propre, connectable au réseau général de distribution électrique de l'endroit où il se trouve. De même l'imprimante dispose d'une alimentation qui lui est également propre et qui est raccordable à ce même réseau. Cette disposition est illustrée par le document JP-A-05 069577 où, pour des raisons de faible coût l'alimentation comporte une batterie rechargeable et un chargeur de batterie.The association of a printer and a terminal of an information processing facility is known in itself. In general, the terminal has a its own power supply, connectable to the network general electrical distribution of where it is find. Likewise the printer has a power supply which it is also clean and which can be connected to the same network. This arrangement is illustrated by document JP-A-05 069577 where, for reasons of low cost food includes a rechargeable battery and a charger drums.
Dans le document US-A-5.110.226, il est décrit un appareil portable formé d'un microprocesseur et d'une imprimante déconnectables dans lequel, soit les deux parties sont alimentées indépendamment l'une de l'autre par des batteries soit, lorsque l'appareil est relié à un réseau de communication, l'énergie électrique est fournie aux deux parties par une alimentation nécessairement dimensionnée à la somme des besoins de ces deux parties.In document US-A-5,110,226, there is described a portable device formed by a microprocessor and a disconnectable printer in which either parts are fed independently of each other by batteries either, when the device is connected to a communication network, electrical energy is supplied to both parties by feeding necessarily sized to the sum of the needs of these two parties.
Par la présente invention on propose une imprimante dont l'alimentation électrique est connectable directement au terminal, quelles que soient les caractéristiques de son alimentation, et malgré le fait qu'en général cette alimentation soit dimensionnée aux seuls besoins du terminal. Il n'est plus ainsi besoin de connecter l'imprimante au réseau de distribution d'énergie ce qui simplifie le matériel en supprimant une prise de raccordement de l'imprimante au réseau de distribution et en supprimant la contrainte pour l'utilisateur de prévoir un endroit spécifique pour cette connexion.By the present invention there is provided a printer whose power supply is connectable directly at the terminal, whatever the characteristics of his diet, and despite the fact that in general this power supply is sized only for the needs of the terminal. There is no longer any need to connect the printer to the energy distribution network which simplifies the hardware by removing a connection socket from the printer to the distribution network and removing the constraint for the user to provide a place specific for this connection.
A cet effet l'invention a donc pour objet la combinaison d'un terminal et d'une imprimante d'une installation de traitement de données comprenant d'une part, un terminal comportant son alimentation en énergie électrique dimensionnée à son besoin spécifique et une prise multibroche de sortie ayant deux broches au moins destinées à la transmission de données et deux autres broches entre lesquelles est présente une tension d'alimentation dérivée de ladite alimentation spécifique et d'autre part, une imprimante dont l'alimentation électrique est assurée par une batterie d'accumulateur rechargeable, le système comprenant une liaison électrique de charge de la batterie rechargeable, connectée aux broches de sortie présentant une tension dérivée de l'alimentation spécifique du terminal.To this end the invention therefore relates to the combination a terminal and a printer of a treatment plant data comprising on the one hand, a terminal comprising its electric power supply sized to its specific need and a multi-pin outlet having at least two pins for the transmission of data and two other pins between which is has a supply voltage derived from said specific power supply and secondly, a printer whose power supply is provided by a battery rechargeable battery, the system comprising a electric connection for charging the rechargeable battery, connected to output pins with voltage derived from the terminal's specific power supply.
Les avantages et d'autres caractéristiques de l'invention ressortiront de la description donnée ci-après d'un exemple de sa réalisation.The benefits and other features of the invention will emerge from the description given below of an example of its realization.
Il sera fait référence au dessin annexé qui, par une figure unique, représente schématiquement une imprimante par exemple thermique conforme à l'invention associée à un terminal d'une installation de traitement de données.Reference will be made to the appended drawing which, by a single figure, schematically represents a printer for example thermal according to the associated invention at a terminal of a data processing installation.
Le terminal en question est représenté sur la
figure sous la forme d'un téléviseur 1, comportant un
cordon d'alimentation 2, une liaison 3 avec une unité
centrale ou un réseau non représenté, et un câble de
liaison 4 destinée à être connecté à une imprimante
thermique 5. L'alimentation de l'imprimante thermique est
quant à elle assurée par une batterie rechargeable connectée
à l'alimentation du terminal 1 au moyen du câble de
liaison 4. La prise de sortie 7 à l'arrière du terminal 4
est, de manière générale, multibroche. Entre deux de ses
broches, il existe une tension d'alimentation dérivée de
l'alimentation spécifique du terminal. De la même manière
la prise d'entrée 8 de l'imprimante 5 comporte ces mêmes
broches si bien que le câble 4 assure la connexion de la
batterie rechargeable à l'alimentation du terminal 1. A
titre d'exemple on indiquera que la liaison 4 est du type
RS 485 6 fils avec prise RJ11, deux fils n'étant pas
connectés, deux servant à la transmission de données et
deux servant à l'alimentation par exemple 9V. Cette
batterie d'accumulation 6 est donc rechargée par des
courants faibles détournés de l'alimentation du terminal 1
qui, bien que dimensionnée aux besoins propres de ce
terminal, autorise ce branchement en parallèle d'une
batterie rechargeable.The terminal in question is represented on the
figure in the form of a
Dans ce type d'application, l'utilisation de
l'imprimante 5 est épisodique, si bien que le temps pendant
lequel la batterie est sollicitée pour fournir de l'énergie
à l'imprimante est très nettement inférieur au temps
pendant lequel le courant faible issu de l'alimentation du
terminal 1 charge cette batterie. En outre, lorsque
l'imprimante 5 fait appel à la source d'énergie, il s'agit
en général d'un appel de courants forts pendant de brefs
intervalles de temps. L'alimentation du terminal 1 ne peut
pas délivrer d'énergie sous cette forme. En revanche, la
batterie rechargeable 6 est capable de convenir parfaitement
aux besoins en énergie de l'imprimante 5.In this type of application, the use of
L'invention a pour principal avantage de simplifier les connexions entre un terminal et une imprimante annexe destinée à constituer une preuve écrite des données portées ou transitant à travers ce terminal d'installation de traitement de données.The main advantage of the invention is to simplify connections between a terminal and a printer appendix intended to constitute a written proof of the data carried or transiting through this installation terminal data processing.
