DISPOSITIF PORTABLE DE TRAITEMENT DE L'INFORMATION, A PORTABLE INFORMATION PROCESSING DEVICE, A
USAGE EDUCATIF, INFORMATIF, PERSONNEL OU DOMESTIQUEEDUCATIONAL, INFORMATIVE, PERSONAL OR DOMESTIC USE
L'invention concerne un dispositif portable de traitement de l'information, à usage éducatif, informatif, personnel ou domestique, du type comprenar.- un micro-processeur associé à une mémoire de travail ez une mémoire de programme, un écran d'affichage et un clavier à touches. On connaît déjà des micro-ordinateurs portables ou portatifs, comprenant en général un boîtier dont le couvercle est formé par un écran plat, par exemple à cristaux liquides, et la base par un clavier comprenant un nombre de touches relativement élevé, en général supérieur à 80. Pour fonctionner, un tel micro¬ ordinateur doit comprendre au moins un logiciel d'exploitation, auquel est le plus souvent associé ur- logiciel d'application spécifique (traitement de texte, calcul, tableur, bases de données, etc.) . Dans les deux cas, il faut posséder de bonnes connaissances du système d'exploitation et/ou du logiciel d'application spécifique, pour pouvoir utiliser ce micro-ordinateur.The invention relates to a portable device for processing information, for educational, informative, personal or domestic use, of the type comprising: a microprocessor associated with a working memory and a program memory, a display screen. and a keypad. Portable or portable microcomputers are already known, generally comprising a housing the cover of which is formed by a flat screen, for example with liquid crystal, and the base by a keyboard comprising a relatively large number of keys, generally greater than 80. To operate, such a microcomputer must include at least one operating software, which is most often associated with specific application software (word processing, calculation, spreadsheet, databases, etc.). In both cases, you must have a good knowledge of the operating system and / or specific application software to be able to use this microcomputer.
De plus, sur un plan purement pratique, il es- préférable de savoir' se servir correctement d'un clavier de machine à écrire si l'on veut ne pas perdre un temps important à taper les questions, instructions ou réponses sur le clavier du micro-ordinateur.In addition, on a purely practical level, it es better to know 'successful use of a machine keyboard to write if you will not lose an important time to type questions, instructions or answers on the keyboard microcomputer.
Enfin, bien que ce type de micro-ordinateur soit portable, il reste cependant relativement encombrant: et lourd.Finally, although this type of microcomputer is portable, it remains relatively bulky: and heavy.
Le besoin se fait sentir actuellement d'un dispositif portable de traitement de l'information, qui soit léger, peu encombrant, utilisable directement par toute personne sans nécessité d'apprendre un système d'exploitation ou un logiciel spécifique, et qui soi d'application à peu près universelle. L'invention a précisément pour but ce répondre à ce besoin.The need is currently felt for a portable device for processing information, which is light, compact, usable directly by any person without the need to learn an operating system or specific software, and which is almost universal application. The object of the invention is precisely to meet this need.
Elle propose à cet effet un dispositif portable de traitement de l'information, à usage 5 éducatif, informatif, personnel ou domestique, comprenant un micro-processeur associé à une mémoire de travail et une mémoire de programme, un écran d'affichage et un clavier à touches, caractérisé en ce qu'il se présente sous forme d'un écran plat, par exemple à cristaux li-To this end, it provides a portable information processing device, for educational, informative, personal or domestic use, comprising a microprocessor associated with a working memory and a program memory, a display screen and a keyboard with keys, characterized in that it is in the form of a flat screen, for example with liquid crystals

Avantageusement, ce logiciel d'applicationAdvantageously, this application software
25 spécifique est un logiciel du type traitement de questions à choix multiple.25 specific is software of the multiple choice question processing type.
Le dispositif selon l'invention peut ainsi avoir un nombre très réduit de touches, par exemple infé¬ rieur ou égal à 12, qui sont uniquement des touches deThe device according to the invention can thus have a very reduced number of keys, for example less than or equal to 12, which are only keys of
30 fonctions spécialisées. Les fonctions associées aux di¬ verses touches dans le cadre d'un logiciel d'application spécifique peuvent être affichées sur l'écran, pour faciliter la manipulation du dispositif selon l' invention.30 specialized functions. The functions associated with the various keys in the context of specific application software can be displayed on the screen, to facilitate handling of the device according to the invention.
35 Un tel dispositif fonctionne sans système d'exploitation particulier et ne nécessite pas l'apprentissage de l'utilisation d'un logiciel d'application. En fait, c'est le système informatique qui fournit des informations, des questions ou des réponses à l'utilisateur, et l'utilisateur se contente de sélection- ner, d'accepter ou de refuser.35 Such a device operates without a particular operating system and does not require learning to use application software. In fact, it is the computer system that provides information, questions or answers to the user, and the user simply selects, accepts or refuses.
On comprend donc qu'un tel dispositif peut avoir un format de poche, et que c'est la taille de l'écran d'affichage qui va déterminer les dimensions du dispositif. Selon une autre caractéristique de l'invention, ce dispositif comprend des moyens de connexion à un système informatique indépendant, constitué par au moins une association micro-processeur- mémoire et capable d'exécuter un logiciel éventuellement complexe, pré-enregistré dans sa mémoire.It is therefore understood that such a device can have a pocket size, and that it is the size of the display screen that will determine the dimensions of the device. According to another characteristic of the invention, this device comprises means for connection to an independent computer system, consisting of at least one microprocessor-memory association and capable of executing possibly complex software, prerecorded in its memory.
De préférence, les moyens de connexion du dispositif avec ce système informatique indépendant sont du type canal à canal.Preferably, the means of connection of the device with this independent computer system are of the channel-to-channel type.

De la sorte, c'est toujours le logiciel du système indépendant qui est exécuté lorsque ce système est connecté au dispositif selon l'invention, et c'est le logiciel d'application spécifique du dispositif qui est exécutable dès que l'on déconnecte le système indépendant. Les applications d'un tel dispositif sont mul¬ tiples :In this way, it is always the software of the independent system which is executed when this system is connected to the device according to the invention, and it is the application software specific to the device which is executable as soon as the disconnected the independent system. The applications of such a device are multiple:
- enseignement assisté par ordinateur : le lo¬ giciel d'application spécifique enregistré dans la mé¬ moire programme du dispositif est alors, par exemple, un logiciel de traitement de questions à choix multiple, les questions elles-mêmes avec leurs réponses et des commen- taires éventuels étant enregistrés sur des cartes à mémoire par catégorie, par discipline, etc.- computer-assisted teaching: the specific application software recorded in the device's memory program is then, for example, multiple choice question processing software, the questions themselves with their answers and beginnings - if any, being recorded on memory cards by category, by discipline, etc.

Dans l'exemple représenté, le dispositif selon l'invention a la forme d'un boîtier plat 10 de forme rectangulaire, dont la majeure partie de la face avant est occupée par un écran d'affichage 12, par exemple à cristaux liquides. Cette face avant comprend également deux touches 14, dans ses angles supérieurs gauche et droit. La petite face supérieure horizontale 16 du boîtier comprend également deux touches 18 au voisinage de ses extrémités. La face arrière du boîtier 10, repré¬ sentée en figure 2, comprend quatre touches 20 le long de chacun de ses bords verticaux, et une cavité ou un emplacement creux 22 de réception d'un système informatique indépendant. Le boîtier 10 comprend en outre un moyen de lecture de données enregistrées sur un support indépendant, par exemple des moyens 24 de lecture d'une carte à mémoire, comprenant un logement plat qui débouche sur un des côtés, par exemple la face supérieure horizontale 16, du boîtier 10. A l'intérieur du boîtier 10 sont logés les éléments suivants :In the example shown, the device according to the invention has the form of a flat box 10 of rectangular shape, the major part of the front face of which is occupied by a display screen 12, for example with liquid crystals. This front face also includes two keys 14, in its upper left and right corners. The small horizontal upper face 16 of the housing also includes two keys 18 in the vicinity of its ends. The rear face of the housing 10, shown in FIG. 2, comprises four keys 20 along each of its vertical edges, and a cavity or a hollow location 22 for receiving an independent computer system. The housing 10 further comprises means for reading data recorded on an independent medium, for example means 24 for reading a memory card, comprising a flat housing which opens on one of the sides, for example the horizontal upper face 16 , of the housing 10. Inside the housing 10 are housed the following elements:
- un micro-processeur 26 associé à une mémoire dynamique 28 du type RAM et une mémoire programme 30 du type ROM et qui est relié de façon classique à l'écran d'affichage 12 et au clavier 32 constitué par les touches 14, 18 et .20, ainsi qu'à un haut-parleur HP,a microprocessor 26 associated with a dynamic memory 28 of the RAM type and a program memory 30 of the ROM type and which is conventionally connected to the display screen 12 and to the keyboard 32 constituted by the keys 14, 18 and .20, as well as an HP speaker,
- un émetteur 34 à infrarouges ou ultrasons, utilisé pour la télécommande d'un poste de télévision, d'un magnétoscope, d'un lecteur laser, etc.. - un circuit 36 de liaison télématique, permettant de connecter le dispositif selon l'invention soit à un micro-ordinateur, par une liaison série ou parallèle, soit à un terminal de liaison à un réseau du type Télétel (terminal Minitel par exemple) pourvu d'un circuit modem, - des moyens 38 de connexion' à un système informatique indépendant 40, logé dans la cavité 22 du boîtier et comprenant au moins un micro-processeur 42 associé à une mémoire dynamique 44 et une mémoire de programme 46. Le système indépendant 40 est de préférence une unité maîtresse, sous la commande de laquelle travaillera le micro-processeur 26 pour exécuter un logiciel enregistré dans la mémoire 46 du système 40 et en utilisant des données lues par le circuit 24 dans une carte à mémoire, ou bien contenues dans la mémoire 28 ou 30.- an infrared or ultrasonic transmitter 34, used for the remote control of a television set, a video recorder, a laser reader, etc. - a telematic link circuit 36, making it possible to connect the device according to the invention or to a microcomputer, through a series connection or parallel or to a connecting terminal to a network such Télétel (Minitel terminal, for example) provided with a modem circuit, - means 38 for connection 'on a computer system independent 40, housed in the cavity 22 of the housing and comprising at least one microprocessor 42 associated with a dynamic memory 44 and a program memory 46. The independent system 40 is preferably a master unit, under the control of which will work the microprocessor 26 for executing software stored in the memory 46 of the system 40 and using data read by the circuit 24 in a memory card, or else contained in the memory 28 or 30.
Le système 40 est de préférence du type invio¬ lable, c'est-à-dire que ses composants 42, 44 et 46 ne sont pas accessibles de l'extérieur, sauf par la liaison 38, sans destruction complète du système. La liaison 38 est de préférence du type canal à canal, bien connue des spécialistes, et qui comporte pour chaque micro¬ processeur un registre directement implanté sur un bus de données du micro-processeur associé, et une bascule dont des entrées sont reliées à des circuits décodeurs d'adresses de lecture et d'écriture. Ce type de liaison est simple à réaliser, peu coûteux et très performant.The system 40 is preferably of the invio¬ lable type, that is to say that its components 42, 44 and 46 are not accessible from the outside, except by the link 38, without complete destruction of the system. The link 38 is preferably of the channel-to-channel type, well known to specialists, and which comprises for each microprocessor a register directly implanted on a data bus of the associated microprocessor, and a flip-flop whose inputs are connected to read and write address decoder circuits. This type of connection is simple to carry out, inexpensive and very efficient.
On notera en outre que la liaison entre le dispositif selon l'invention et le système informatique indépendant 40 s'effectue de micro-processeur à micro¬ processeur, sans permettre d'accéder directement à un logiciel éventuellement très complexe enregistré dans les mémoires du système 40. Ce logiciel est ainsi particulièrement bien protégé contre les tentatives de copie ou de piratage. Il peut s'agir par exemple d'un logiciel expert, du type posant des questions à l'utilisateur, travaillant sur les réponses et donnant une conclusion finale. Ce logiciel sera du type auto¬ exécutable sans système d'exploitation du type MS-DOS ou UNIX (marques enregistrées) de façon à pouvoir se dérouler en ne demandant à l'utilisateur que d'actionner quelques touches de fonctions spécialisées.It will also be noted that the connection between the device according to the invention and the independent computer system 40 is carried out from microprocessor to microprocessor, without allowing direct access to possibly very complex software stored in the memories of the system. 40. This software is therefore particularly well protected against copying or pirating attempts. It can be for example an expert software, of the type asking questions to the user, working on the answers and giving a final conclusion. This software will be of the self-executing type without an operating system of the MS-DOS or UNIX type (registered marks) so as to be able to run without asking the user to actuate a few specialized function keys.
Le fonctionnement du dispositif selon l'invention découle à l'évidence de ce qui précède : lorsqu'aucun système indépendant 40 n'est connecté au micro-processeur 26 du dispositif, c'est un logiciel d'application spécifique enregistré dans la mé¬ moire 30 du dispositif qui sera automatiquement exécuté. Les données auxquelles s'appliquera ce logiciel sont contenues par exemple dans une carte à mémoire, du format carte de crédit par exemple, qui est lue par le circuit 24. Les touches de fonction 14, 18 et 20 permettent de commander le fonctionnement du dispositif et le déroulement du logiciel, chaque touche ayant une fonction qui est de préférence affichée sur l'écran 12 et qui correspond à une sélection, à une acceptation ou à un refus par l'utilisateur, éventuellement à une demande d'explication ("guide") et à un agrandissement d'une partie de l'information affichée sur l'écran ("loupe").The operation of the device according to the invention obviously follows from the above: when no independent system 40 is connected to the microprocessor 26 of the device, it is specific application software recorded in the me¬ moire 30 of the device which will be automatically executed. The data to which this software will apply is contained for example in a memory card, of the credit card format for example, which is read by the circuit 24. The function keys 14, 18 and 20 make it possible to control the operation of the device and the progress of the software, each key having a function which is preferably displayed on the screen 12 and which corresponds to a selection, acceptance or rejection by the user, possibly a request for explanation ("guide ") and to enlarge some of the information displayed on the screen (" magnifying glass ").
Le logiciel en question est par exemple du type permettant le traitement standard de questions à choix multiple qui sont enregistrées avec leurs réponses et des commentaires éventuels sur une carte à mémoire. De façon générale, ce logiciel est du type "stand-alone", c'est-à-dire auto-exécutable sans système d'exploitation et ne demande à l'utilisateur que des choix logiques (sélectiqn, acceptation, refus) .The software in question is, for example, of the type allowing standard processing of multiple choice questions which are recorded with their answers and possible comments on a memory card. In general, this software is of the "stand-alone" type, that is to say self-executable without an operating system and only asks the user for logical choices (selection, acceptance, refusal).
Lorsqu'un système informatique indépendant 40 est connecté au dispositif selon l'invention, c'est automatiquement le programme ou logiciel chargé dans la mémoire 46 de ce système qui sera exécuté. Les données auxquelles ce logiciel sera appliqué seront prélevées sur une carte à mémoire lue par le circuit 24, ou bien dans les mémoires 28 et 30 du dispositif.When an independent computer system 40 is connected to the device according to the invention, it is automatically the program or software loaded in the memory 46 of this system which will be executed. The data to which this software will be applied will be taken from a memory card read by circuit 24, or else in memories 28 and 30 of the device.
Il suffit donc de changer de carte à mémoire et/ou de système indépendant 40, pour changer l'application ou l'utilisation du dispositif et passer par exemple d'un système de jeu à un enseignement assisté ou à un traitement de notice technique ou juridique. Les cartes à mémoire peuvent comprendre uniquement des mémoires, ou bien des mémoires associées à des microprocesseurs et contenant des informations codées ou non.It therefore suffices to change the memory card and / or independent system 40, to change the application or the use of the device and move, for example, from a game system to assisted teaching or to processing of technical instructions or legal. The memory cards can comprise only memories, or else memories associated with microprocessors and containing coded or non-coded information.
L'émetteur 34 permet la télécommande d'un appareil électronique dont les spécifications sont par exemple enregistrées dans une mémoire 28 ou 30 du dispositif ou sur une carte à mémoire lue par le circuit 24.The transmitter 34 allows the remote control of an electronic device whose specifications are for example recorded in a memory 28 or 30 of the device or on a memory card read by the circuit 24.
Le circuit 36 permet, par connexion du dispo¬ sitif à un micro-ordinateur ou à un réseau de télétransmission, d'enregistrer des données et/ou des logiciels dans la mémoire dynamique 28.The circuit 36 allows, by connection of the device to a microcomputer or to a remote transmission network, to record data and / or software in the dynamic memory 28.
De façon générale, toutes les opérations de gestion des entrées/sorties sont réalisées par le micro¬ processeur 26, en exécution d'un programme de gestion d'entrées/sorties enregistré à demeure dans la mémoire 30 du dispositif. Les organes d'entrées/sorties ainsi commandés sont bien entendu le haut-parleur, l'écran d'affichage 12, le clavier 32, le circuit 24 de lecture de carte à mémoire, l'émetteur 34, le circuit 36 de liaison télématique et les moyens de connexion 38 à un système informatique indépendant 40.In general, all the input / output management operations are carried out by the microprocessor 26, in execution of an input / output management program permanently stored in the memory 30 of the device. The input / output members thus controlled are of course the loudspeaker, the display screen 12, the keyboard 32, the memory card reading circuit 24, the transmitter 34, the telematic link circuit 36 and the means of connection 38 to an independent computer system 40.
Pour fixer les idées, on précisera que le mi¬ cro-processeur 26 peut être du type compatible Z 80 de Zilog, par exemple un circuit HITACHI HD 64180. Les mémoires 28 et 30 associées à ce micro-processeur peuvent avoir une capacité d'un megaoctet. L'écran 12 à cristaux liquides comprend par exemple 20 lignes de 80 caractères. Le dispositif a des dimensions de l'ordre deTo fix the ideas, it will be specified that the microprocessor 26 can be of the Zilog Z 80 compatible type, for example a HITACHI HD 64180 circuit. The memories 28 and 30 associated with this microprocessor can have a capacity of one megabyte. The liquid crystal screen 12 comprises for example 20 lines of 80 characters. The device has dimensions of the order of
24 cm x 13 cm x 2 cm et est alimenté soit par batterie ou pile, soit par connexion au réseau électrique au moyen d'un transformateur. Le dispositif selon l'invention peut avoir d'autres applications particulières que celles déjà citées, par exemple de traitement d'une carte à mémoire représentant un crédit quelconque, et d'affichage du crédit disponible. Le dispositif peut aussi comprendre des moyens d'affichage numérique de la date et de l'heure. Une application possible concerne le paiement des heures de stationnement automobile, dans la rue ou dans un garage.24 cm x 13 cm x 2 cm and is powered either by battery or by connection to the electrical network by means of a transformer. The device according to the invention may have other specific applications than those already mentioned, for example for processing a memory card representing any credit, and for displaying the available credit. The device may also include means for digital display of the date and time. One possible application concerns the payment for hours of car parking, on the street or in a garage.
Il est par ailleurs bien évident que des modifications peuvent être apportées au dispositif décrit, sans sortir du cadre de l'invention : par exemple, l'écran peut être du type sensitif ou tactile et les touchés sont alors simplement dessinées sur l'écran.It is moreover quite obvious that modifications can be made to the device described, without departing from the scope of the invention: for example, the screen can be of the sensitive or tactile type and the touchdowns are then simply drawn on the screen.
De façon générale, les touches sont disposées de façon à se présenter naturellement sous les doigts quand on tient le dispositif à la main. Les touches prévues au dos du boîtier peuvent être à surface gravée ou spécifique, permettant de les identifier au toucher.Generally, the keys are arranged so that they appear naturally under the fingers when the device is held in the hand. The keys provided on the back of the case can have an engraved or specific surface, allowing them to be identified by touch.
Le dispositif selon l'invention n'est pas li- mité à un format de poche. L'écran peut par exemple être de taille standard, ou de grande taille, et les quelques touches du clavier peuvent être, au moins en partie, rem¬ placées par (ou associées à) un système de déplacement de curseur à télécommande (appelé "souris" dans la technique courante) comportant par exemple quelques touches de fonction .en plus des moyens habituels de déplacement de curseur.The device according to the invention is not limited to a pocket size. The screen can for example be of standard size, or of large size, and the few keys of the keyboard can be, at least in part, replaced by (or associated with) a system for moving the cursor by remote control (called " mouse "in the current technique) comprising for example a few function keys. in addition to the usual means of moving the cursor.
Un mode particulier de réalisation de l'invention a été représenté en figure 4. L'écran 12 à cristaux liquides comprend 25 lignes de 80 caractères chacune et le long d'un de ses petits côtés sont disposées des touches 50, qui sont des touches numériques ou des touches de sélection associées à des zones de l'écran et permettant de réaliser plus rapidement une sélection d'informations. Des touches d'annulation 52, de déplacement du curseur'vers la gauche et la droite 54, d'affichage d'un guide 56 et de validation 58 sont prévues le long des autres côtés de l'écran 12.A particular embodiment of the invention has been shown in FIG. 4. The liquid crystal screen 12 comprises 25 lines of 80 characters each and along one of its short sides are arranged keys 50, which are numeric keys or selection keys associated with areas of the screen and allowing faster selection of information. Cancellation keys 52, movement of the cursor to the left and right 54, display of a guide 56 and validation 58 are provided along the other sides of the screen 12.
Le boîtier 10 a, dans cet exemple, les dimensions suivantes : 24 x 18 x 2 cm. La fente 24 d'introduction d'une carte à mémoire est prévue sur l'un de ses petits côtés, au voisinage de deux connecteurs 60 de liaison série et parallèle respectivement à un système informatique. Sur la face avant du boîtier 10, sous l'écranThe case 10 has, in this example, the following dimensions: 24 x 18 x 2 cm. The slot 24 for inserting a memory card is provided on one of its short sides, in the vicinity of two connectors 60 for serial and parallel connection respectively to a computer system. On the front face of the housing 10, under the screen
12, on peut encore prévoir un logement 62, destiné à re¬ cevoir un clavier plat formé d'une feuille sur laquelle des touches sont représentées par un système de code à barres lisibles par un crayon optique. Ce type de clavier facilement interchangeable peut être utile pour certaines applications particulières.12, it is also possible to provide a housing 62, intended to receive a flat keyboard formed from a sheet on which keys are represented by a bar code system readable by an optical pencil.
