Description

La présente invention concerne un boítier portable au poignet au moyen d'un bracelet et comportant un clavier supporté, ni par le boítier, ni par le bracelet mais associé à ce dernier. Le clavier comporte des touches permettant d'entrer des données dans une unité de traitement contenue dans le boítier comportant également un dispositif d'affichage pour afficher les données introduites ou le résultat d'un traitement particulier, et une source d'énergie pour alimenter les composants électroniques. Ce boítier portable a de préférence la forme d'une montre-bracelet.The present invention relates to a portable wrist case by means of a bracelet and having a keyboard supported, neither by the case, nor by the bracelet but associated with the latter. The keyboard has keys for entering data in a processing unit contained in the case also comprising a display device for displaying the data entered or the result of a particular treatment, and an energy source to power the components e. This portable case preferably has the shape of a wristwatch.

La montre-bracelet étant devenue un accessoire a peu près indispensable dans la vie quotidienne, et donc portée en permanence au poignet, on a cherché à lui incorporer d'autres fonctions devenues tout aussi indispensables à un usager que la connaissance de l'heure. Il a ainsi été incorporé dans le boítier de la montre-bracelet des dispositifs fonctionnels supplémentaires permettant par exemple d'avoir une fonction calculatrice, boussole, thermomètre, biologique (par exemple rythme cardiaque), téléphone et bien d'autres encore. Dans certains cas il est possible d'initialiser l'unité de traitement pour l'une de ces fonctions par pression sur un unique bouton-poussoir, par exemple pour passer d'un mode affichage horaire à l'affichage du rythme cardiaque. Dans d'autres cas, par exemple passage en mode calculatrice ou téléphone, il est nécessaire de disposer d'un plus grand nombre de zones de pression différenciées, c'est-à-dire d'un clavier à touches. Ces touches ont d'abord été placées sur des extensions rigides du bracelet, et ensuite pour les rendre plus ergonomiques sur les brins de bracelet à proximité du boítier. Le brevet US 4,255,801 décrit une montre électronique comportant une calculatrice ayant un bracelet à maillons comportant d'un côté des touches en relief pour les chiffres, et de l'autre côté des touches en relief pour les fonctions de calcul. Dans le brevet US 4,141,074 toutes les touches de la calculatrice sont portées par le même brin de bracelet. Toutes les touches sont reliées à une unité centrale de traitement située à l'intérieur du boítier par une bande de fils conducteurs, passant d'un maillon à l'autre pour finalement traverser le boítier. Dans une telle construction, il est évident qu'il existe un risque de détérioration de la bande de fils conducteurs lors de la manipulation du bracelet en torsion et surtout en traction lorsqu'on fixe la montre-bracelet au poignet, ou inversement lorsqu'on l'enlève. Même si certains dispositifs ont été proposés pour connecter facilement les touches à l'unité de traitement, et donc permettre de remplacer un bracelet-clavier usagé, cela constitue pour l'usager un surcoût bien supérieur à celui d'un simple bracelet. On observera également que les touches en relief sont exposés à de nombreuses agressions extérieures, tels que les frottements ou les chocs par exemple lorsque l'usager pose son poignet sur une table. On notera enfin qu'un clavier apparent révèle la complexité et donc la valeur de l'objet porté au poignet mais présente un aspect esthétique assez contestable.The wristwatch having become an almost indispensable accessory in everyday life, and therefore worn permanently on the wrist, we sought him incorporate other functions that have become just as essential to a user as the knowledge of the time. It was thus incorporated into the case of the wristwatch additional functional devices allowing for example to have a calculator, compass, thermometer, biological function (e.g. rhythm cardiac), telephone and many more. In some cases it is possible initialize the processing unit for one of these functions by pressing a single push button, for example to switch from time display mode to display heart rate. In other cases, for example switching to calculator mode or telephone, there is a need for more areas of differentiated pressure, that is to say a keyboard with keys. These keys were first placed on rigid extensions of the bracelet, and then to make them more ergonomic on the bracelet strands near the case. US Patent 4,255,801 describes an electronic watch comprising a calculator having a bracelet with links with embossed number buttons on one side and on the other side raised keys for the calculation functions. In US patent 4,141,074 all the keys of the calculator are carried by the same strand of bracelet. All the keys are connected to a central processing unit located inside the case by a strip of conductive wires, passing from one link to another to finally cross the housing. In such a construction, it is obvious that there is a risk of deterioration of the strip of conductive wires when handling the bracelet in torsion and especially in traction when the wristwatch is attached to the wrist, or conversely when removed. Even if certain devices have been proposed for easily connect the keys to the processing unit, and therefore allow replace a worn keyboard bracelet, this constitutes an additional cost for the user superior to that of a simple bracelet. It will also be observed that the keys in relief are exposed to numerous external aggressions, such as friction or shocks, for example when the user places his wrist on a table. We will note finally that an apparent keyboard reveals the complexity and therefore the value of the object brought to the wrist but has a rather questionable aesthetic appearance.

Le brevet US 5,020,039 décrit un bracelet souple constitué de deux bandes élastomères prenant en sandwich des contacteurs dont les emplacements et les fonctions sont imprimés sur la bande supérieure. On n'a donc plus de maillons articulés, ni des touches en relief, ce qui permet de supprimer une partie des inconvénients susmentionnés. La construction proposée n'apporte toutefois pas de solution au risque de rupture des fils conducteurs reliant les contacteurs, lors d'une traction sur le bracelet, et l'aspect esthétique n'a que faiblement été amélioré.US Patent 5,020,039 describes a flexible bracelet made up of two bands elastomers sandwiching contactors whose locations and functions are printed on the upper strip. So there are no more links articulated, or raised keys, which removes some of the disadvantages mentioned above. The proposed construction does not, however, solution to the risk of breakage of the conductive wires connecting the contactors, during a traction on the bracelet, and the aesthetic appearance has only slightly improved.

La présente invention a pour but de pallier les inconvénients de l'art antérieur susmentionné en procurant un boítier pouvant être fixé au poignet au moyen d'un bracelet ne comportant aucun clavier, mais qui sert également à protéger et à masquer un clavier sous-jacent permettant l'introduction de données alphanumérique et/ou à fonctionnelles dans une unité de traitement contenue dans le boítier.The present invention aims to overcome the drawbacks of the prior art mentioned above by providing a case which can be fixed to the wrist by means of a bracelet with no keyboard, but which also protects and protects hide an underlying keyboard allowing the input of alphanumeric data and / or functional in a processing unit contained in the housing.

A cet effet l'invention a pour objet un boítier portable comprenant des moyens d'attache d'un bracelet à un poignet et des moyens de connexion d'un support souple d'un clavier à touches portant des caractères alphanumériques ou des signes de fonction correspondant par exemple à un clavier de calculatrice ou à un clavier simplifié d'ordinateur. Le clavier est relié à l'intérieur du boítier à une unité de traitement de données commandant un dispositif d'affichage permettant d'afficher sur un cadran du boítier des caractères fournis par l'unité de traitement, l'alimentation électrique des composants électroniques desdits dispositif d'affichage et unité de traitement étant fournie par une source d'énergie. Le boítier est caractérisé en ce que le support souple du clavier est connecté sur un côté dudit boítier en ayant une longueur correspondant sensiblement au tour de poignet et en ce que le bracelet recouvre totalement le clavier en étant pourvu d'un moyen d'attache fixe diamétralement opposé aux moyens de connexion du clavier et d'un moyen d'attache amovible situé au niveau de ladite connexion.For this purpose the invention relates to a portable housing comprising means for attaching a bracelet to a wrist and means for connecting a flexible support a keypad with alphanumeric characters or signs function corresponding for example to a calculator keyboard or a keyboard simplified computer. The keyboard is connected inside the case to a unit of data processing controlling a display device allowing to display on a dial of the box of characters provided by the processing unit, the power supply electrical components of said display device and unit treatment being provided by an energy source. The housing is characterized in that the flexible support of the keyboard is connected to one side of said housing having a length corresponding substantially to the wrist and in that the bracelet completely covers the keyboard, being provided with a fixed attachment means diametrically opposite to the keyboard connection means and an attachment means removable located at said connection.

Dans un mode de réalisation préféré le boítier est un boítier de montre contenant également un mouvement permettant d'afficher sur le cadran des fonctions horaires de façon analogique ou digitale. Lorsque la montre-bracelet est portée au poignet, le clavier est entièrement masqué et protégé et la montre-bracelet a l'aspect de toutes les montres-bracelets, ce qui permet de grandes variations sur le plan esthétique. Lorsqu'on veut utiliser sa fonction additionnelle, par exemple calculatrice ou ordinateur il suffit de la détacher du poignet, de la poser sur une surface plane et de déployer le bracelet d'un côté et le clavier de l'autre côté.In a preferred embodiment the case is a watch case also containing a movement allowing functions to be displayed on the dial timetables in analog or digital form. When the wristwatch is worn wrist, keyboard is completely hidden and protected and the wristwatch looks of all wristwatches, which allows great variations on the plan aesthetic. When you want to use its additional function, for example calculator or computer just detach it from the wrist, place it on a flat surface and deploy the bracelet on one side and the keyboard on the other side.

D'autres caractéristiques et avantages de la présente invention apparaítront plus clairement à la lecture de la description de modes de réalisation d'une montre-bracelet à clavier, donnés à titre d'exemples illustratifs et non limitatifs, en référence aux dessins annexés dans lesquels :

Other characteristics and advantages of the present invention will appear more clearly on reading the description of embodiments of a keyboard wristwatch, given by way of illustrative and nonlimiting examples, with reference to the accompanying drawings in which :
  • Figure 1 shows in perspective, in the position where it is attached to the wrist, a wristwatch with a calculator keyboard;

En se référant d'abord aux figures 1 à 3, on voit qu'on a représenté une montre-bracelet 1A à affichage digital. Elle comprend de façon classique un boítier 2 logeant notamment un circuit garde-temps 9 dont les circuits ou blocs électroniques qui le composent ne seront pas décrits en détail comme étant connus de l'homme de métier dans le domaine de l'horlogerie. Le circuit garde temps 9 commande un dispositif d'affichage à cristaux liquides 6 conventionnel de l'heure de type matriciel, supporté par un cadran 7 protégé par une glace 8. Pour l'alimentation électrique des composants électroniques de ladite montre 1A, le boítier contient aussi une source d'énergie 10 qui est par exemple une pile ou un accumulateur rechargeable par tout moyen connu dans le domaine technique de l'invention. La carrure 12 du boítier 2 comprend également des boutons-poussoirs 5 permettant de commander les fonctions horaires de la montre et/ou une fonction additionnelle non horaire comme cela sera expliqué par la suite.Referring first to Figures 1 to 3, we see that a 1A wristwatch with digital display. It conventionally includes a housing 2 housing in particular a timepiece circuit 9 whose electronic circuits or blocks which compose it will not be described in detail as being known to the man of profession in the field of watchmaking. The timekeeping circuit 9 controls a conventional matrix-type liquid crystal display device 6, supported by a dial 7 protected by a crystal 8. For the electrical supply of electronic components of said watch 1A, the case also contains a source of energy 10 which is for example a battery or an accumulator rechargeable by any means known in the technical field of the invention. Case 12 of case 2 also includes push buttons 5 for controlling the time functions of the watch and / or an additional non-time function such as this will be explained later.

La montre 1A est attachée au poignet au moyen d'un bracelet 3 qui comporte sur un côté de la carrure 12 une attache fixe 4b montée à rotation sur un axe et sur le côté diamétralement opposé une attache amovible 4a formée par une boucle montée à rotation sur la carrure 12 et dans laquelle on engage et on retourne l'extrémité 3a du brin de bracelet 3 comportant une fixation de type Velcro®. The watch 1A is attached to the wrist by means of a bracelet 3 which has on one side of the middle part 12 a fixed fastener 4b rotatably mounted on an axis and on the diametrically opposite side a removable fastener 4a formed by a mounted loop rotating on the middle 12 and in which one engages and returns the end 3a of the bracelet strand 3 comprising a Velcro® type attachment.

Comme on le voit, le bracelet 3 est conçu pour envelopper le poignet et ne s'étendre que d'un côté du boítier 2, comme représenté sur la figure 2, lorsqu'il est détaché du poignet et posé sur une surface plane.As can be seen, bracelet 3 is designed to wrap the wrist and does not extend only on one side of the housing 2, as shown in Figure 2, when it is detached from the wrist and placed on a flat surface.

Selon une caractéristique principale de l'invention, la montre 1A est pourvue d'un clavier 13, indépendant du bracelet 3 et fixé au boítier 2 au niveau d'une zone 12à de la carrure 12, diamétralement opposée à l'attache fixe 4b du bracelet 3. Ainsi, lorsque la montre-bracelet 1A est posée sur une surface plane, seule une petite portion de l'attache amovible 4a masque le clavier 13. Lorsqu'au contraire la montre est attachée au poignet, le clavier 13 est entièrement masqué et protégé par le bracelet 3, comme représenté par les figures 1 et 3, la séparation entre ces deux éléments ayant fortement été exagérée pour une meilleure compréhension. En réalité lorsque la montre est portée au poignet, ces deux éléments sont plaqués l'un contre l'autre. Selon une variante de réalisation, la surface interne du bracelet 3 a une forme complémentaire de celle du clavier 13 pour permettre, en quelque sorte, de l'emboíter et de le masquer totalement.According to a main characteristic of the invention, the watch 1A is provided a keyboard 13, independent of the bracelet 3 and fixed to the case 2 at a zone 12a of the middle 12, diametrically opposite to the fixed attachment 4b of the bracelet 3. When the wrist watch 1A is placed on a flat surface, only a small portion of the removable clip 4a hides the keyboard 13. When, on the contrary, the watch is attached to the wrist, the keyboard 13 is entirely hidden and protected by the bracelet 3, as shown in Figures 1 and 3, the separation between these two elements having been greatly exaggerated for a better understanding. In reality when the watch is worn on the wrist, these two elements are pressed one against the other the other. According to an alternative embodiment, the internal surface of the bracelet 3 has a shape complementary to that of the keyboard 13 to allow, in a way, to fit it and hide it completely.

Dans l'exemple représenté, le clavier 13 est un clavier de calculatrice ayant des touches 14 portant des chiffres et des signes de fonctions inscrits pour être lu perpendiculairement à la longueur du clavier 13, c'est-à-dire dans le même sens que l'affichage horaire 6. Comme cela sera expliqué plus en détails en référence aux figures 4 à 6, le clavier 13 est relié à une unité de traitement 29 logée dans le boítier 2 et permettant d'avoir sur le cadran 7 un affichage matriciel à cristaux liquides 16 des données introduites par l'intermédiaire du clavier 13 et du résultat de l'opération effectuée.In the example shown, the keyboard 13 is a calculator keyboard having keys 14 carrying numbers and signs of functions registered to be read perpendicular to the length of the keyboard 13, that is to say in the same direction as time display 6. As will be explained in more detail with reference to Figures 4 to 6, the keyboard 13 is connected to a processing unit 29 housed in the housing 2 and allowing to have on the dial 7 a liquid crystal matrix display 16 of the data entered via the keyboard 13 and the result of the operation performed.

Le passage en mode calculatrice peut s'effectuer de façon très usuelle en pressant pendant une durée déterminée, par exemple plus de 2 secondes une touche 15 portant le signe C. Bien que le clavier 13 soit protégé par le bracelet 3 lorsque la montre est au poignet, cette mise en fonction différée évite un passage non désiré en mode calculatrice si un choc ou une pression brève est exercée de façon fortuite sur la touche 15 par l'intermédiaire du bracelet 3, par exemple si celui-ci est réalisé en une matière souple. Il est également possible de prévoir le passage en mode calculatrice au moyen d'une pression exercée sur l'un des bouton-poussoir 5.Switching to calculator mode can be carried out in a very usual way by pressing a key for a fixed period, for example more than 2 seconds 15 bearing the sign C. Although the keyboard 13 is protected by the bracelet 3 when the watch is on the wrist, this delayed activation prevents unwanted passage calculator mode if a brief shock or pressure is accidentally exerted on the button 15 via the bracelet 3, for example if the latter is made in a flexible material. It is also possible to plan to switch to calculator by pressing one of the push-buttons 5.

Dans la description qui précède les deux affichages horaires 6 et calcul 16 sont séparés. Selon une variante d'exécution, il est possible de n'avoir qu'un seul affichage matriciel à cristaux liquides en prévoyant dans l'unité de traitement 29 des moyens de commutation entre le mode horaire et le mode calculatrice, ou inversement lorsqu'on exerce une pression sur la touche 15 ou sur un bouton-poussoir 5 comme indiqué précédemment. In the description above, the two time displays 6 and calculation 16 are separated. According to an alternative embodiment, it is possible to have only one liquid crystal matrix display by providing in the processing unit 29 means for switching between time mode and calculator mode, or conversely when pressing the button 15 or on a push button 5 as previously indicated.

En se référant maintenant à la figure 4, on a représenté une montre-bracelet 1B à affichage analogique de l'heure au moyen d'aiguilles 26, comportant un clavier 23, comme précédemment relié au boítier 2 à l'opposé de l'attache fixe 4b du bracelet 3. Le clavier 23 comporte des touches 14 identifiées par des inscriptions alphanumériques et fonctionnelles correspondant à celles d'un clavier d'ordinateur simplifié. Comme on le voit, contrairement au premier mode de réalisation, ces inscriptions sont lisibles parallèlement à la longueur du clavier 23 et peuvent être disposées sur trois rangées et être recouvertes par le bracelet 3 sans nuire à l'aspect esthétique lorsque la montre est portée au poignet. Le clavier 23 est, comme précédemment, connecté à l'intérieur du boítier 2 à une unité de traitement 29 permettant de commander un affichage matriciel à cristaux liquides pouvant comporter plusieurs lignes 16a, 16b,...sur le cadran de la montre, ces lignes étant lisibles dans le même sens que les inscriptions portées par les touches 14 du clavier 23. Dans l'exemple décrit d'un affichage analogique de l'heure le passage des aiguilles 26 au-dessus des zones d'affichage digital 16a, 16b,... constitue une gène acceptable. Selon des techniques connues dans le domaine horloger, il est également possible de superposer temporairement toutes les aiguilles 16 sur la position horaire 12h ou 6h lorsqu'on passe en mode "ordinateur" en pressant un bouton-poussoir 5 ou une touche déterminée 15 du clavier. Selon une autre variante de réalisation, la gène causée par les aiguilles peut être éliminée en optant pour un affichage digital de l'heure. En réalisant un affichage matriciel à cristaux liquides sur la plus grande partie de la surface du cadran 7 et en prévoyant dans l'unité de traitement 29 des moyens de commutation, il est en effet possible de commander, par exemple en exerçant une pression sur un bouton poussoir 5 ou sur une touche déterminée 15 du clavier, un basculement à 90° de l'affichage de sorte que l'affichage de l'heure puisse être lu de façon habituelle, perpendiculairement à la longueur du bracelet 3 lorsque la montre est portée au poignet, et que les lignes d'affichage 16a, 16b... puissent être lues parallèlement à la longueur du bracelet 3 lorsqu'on pose la montre sur une surface plane pour faire usage du clavier 23.Referring now to Figure 4, there is shown a wristwatch 1B with analog time display by means of hands 26, comprising a keyboard 23, as previously connected to the case 2 opposite the fixed clip 4b of the bracelet 3. The keyboard 23 includes keys 14 identified by inscriptions alphanumeric and functional corresponding to those of a computer keyboard simplified. As can be seen, unlike the first embodiment, these inscriptions are readable parallel to the length of the keyboard 23 and can be arranged in three rows and be covered by bracelet 3 without detracting from the appearance aesthetic when the watch is worn on the wrist. The keyboard 23 is, as previously, connected inside the housing 2 to a processing unit 29 for controlling a liquid crystal matrix display that can have several lines 16a, 16b, ... on the watch face, these lines being readable in the same direction as the inscriptions carried by the keys 14 of the keyboard 23. In the example described from an analog time display, the passage of hands 26 above the digital display areas 16a, 16b, ... constitutes a gene acceptable. According to techniques known in the watchmaking field, it is also possible to temporarily superimpose all hands 16 on the time position 12h or 6h when you switch to "computer" mode by pressing a push button 5 or a specific key 15 on the keyboard. According to another alternative embodiment, the gene caused by needles can be eliminated by opting for a digital display of time. By performing a matrix display on liquid crystal on the major part of the surface of the dial 7 and by providing in the processing unit 29 means It is indeed possible to control, for example by exercising a pressing a push button 5 or a specific key 15 on the keyboard, a toggle the display 90 ° so that the time display can be read from usual way, perpendicular to the length of strap 3 when the watch is worn on the wrist, and that the display lines 16a, 16b ... can be read parallel to the length of the strap 3 when the watch is placed on a surface flat to use the keyboard 23.

Dans le mode de réalisation représenté à la figure 4, le bracelet 3 est, comme précédemment, en une seule pièce avec une attache fixe 24 à l'opposé du clavier 23, et une attache amovible en deux parties clipsables, une partie 25 étant montée à rotation au dessus d'une extrémité du clavier 23 et comportant une découpe 25a dans laquelle vient s'engager une languette 27a de la deuxième partie 27. II est bien évident que l'homme de métier peut adapter certains autres systèmes d'attache prévus pour des bracelets à deux brins à un bracelet n'en comportant qu'un seul, comme c'est le cas pour la présente invention. In the embodiment shown in Figure 4, the bracelet 3 is, as previously, in one piece with a fixed clip 24 opposite the keyboard 23, and a removable clip in two clip-on parts, part 25 being mounted at rotation above one end of the keyboard 23 and comprising a cutout 25a in which engages a tongue 27a of the second part 27. It is good obvious that the skilled person can adapt certain other fastening systems intended for bracelets with two strands to a bracelet comprising only one, as is the case for the present invention.

En se référant maintenant à la figure 5 on a représenté en perspective partiellement arrachée une touche 14 d'un caractère alphanumérique du clavier 13 ou 23 réalisé principalement en une matière caoutchouteuse. Une bande de circuit imprimé 32 souple, par exemple un film Capton®, portant des pistes métalliques 20 sur au moins une de ses faces est pris en sandwich entre deux bandes 31 et 33 en un matériaux caoutchouteux. La première bande 31 est conformée pour réaliser les touches 14 et la deuxième bande 33 pour supporter le circuit imprimé souple 32. Chaque touche 14 en forme de cône tronqué comprend sous sa partie supérieure une pastille conductrice 14a formant contacteur lorsqu'elle est pressée pour venir court-circuiter deux pistes métalliques 20. Lorsque la touche est relâchée, l'élasticité du matériau permet de ramener la pastille 14a en position de repos, c'est-à-dire éloignée des pistes 20.Referring now to Figure 5 there is shown in perspective partially torn off a key 14 of an alphanumeric character from the keyboard 13 or 23 made mainly of a rubbery material. A circuit strip flexible print 32, for example a Capton® film, carrying metallic tracks 20 on at least one of its faces is sandwiched between two strips 31 and 33 in one rubbery materials. The first strip 31 is shaped to carry out the keys 14 and the second strip 33 to support the flexible printed circuit 32. Each button 14 in the form of a truncated cone comprises under its upper part a conductive pad 14a forming a contactor when pressed to short-circuit two metal tracks 20. When the key is released, the elasticity of the material makes it possible to bring the pellet 14a back to the rest position, that is to say distant tracks 20.

Dans une variante de réalisation, non représentée, les touches alphanumériques et fonctionnelles 14 du clavier 13 ou 23 peuvent être des touches capacitives ou piézo-résistives sensibles à l'approche ou au contact du doigt d'un utilisateur, ces deux technologies étant bien connues de l'homme de métier.In an alternative embodiment, not shown, the keys alphanumeric and functional 14 of the keyboard 13 or 23 can be keys capacitive or piezoresistive sensitive to the approach or contact of the finger of a user, these two technologies being well known to those skilled in the art.

La figure 6 représente schématiquement les composants électroniques nécessaires pour la transmission des signaux électriques entre les touches 14, 15 du clavier 13 ou 23 et les composants intégrés dans le boítier 2, le clavier étant représenté uniquement par une portion du circuit imprimé souple 32 proche de la carrure 12 et par le prolongement 32a à l'intérieur du boítier 2. Dans le mode de réalisation représenté, le circuit imprimé souple 32 comprend un circuit intégré d'encodage 19 relié d'une part par des pistes métalliques 20 à une série de commutateurs 14a, d'autre part par deux pistes métalliques 17, 18 qui se prolonge sur la portion 32a à l'intérieur du boítier jusqu'à l'unité de traitement 29 alimentée par la source d'énergie 10 et reliée à un circuit d'entraínement 30 du dispositif d'affichage 6 ou 16a, 16b,....Figure 6 schematically shows the electronic components necessary for the transmission of electrical signals between keys 14, 15 of the keyboard 13 or 23 and the components integrated in the housing 2, the keyboard being represented only by a portion of the flexible printed circuit 32 close to the middle 12 and by the extension 32a inside the case 2. In the mode of illustrated embodiment, the flexible printed circuit 32 includes an integrated circuit encoding 19 connected on the one hand by metal tracks 20 to a series of switches 14a, on the other hand by two metal tracks 17, 18 which extends over the portion 32a inside the housing up to the processing unit 29 supplied by the energy source 10 and connected to a drive circuit 30 of the display device 6 or 16a, 16b, ....

Le circuit intégré d'encodage 19 reçoit des signaux d'horloge d'un bloc générateur et comporte un microprocesseur cadencé par le bloc oscillateur ou une logique câblée pour envoyer en série sur la ligne 18 le mot binaire correspondant au symbole de la touche pressée afin que ce mot soit traité par l'unité de traitement 29. L'unité de traitement 29 peut être un microcontrôleur cadencé à une fréquence de l'ordre de 32 KHz fournie par un bloc oscillateur à quartz (non représenté). Il est à noter que le bloc oscillateur du circuit intégré d'encodage 19 et celui de l'unité de traitement 29 peuvent être le même que celui du circuit garde-temps 9 de la montre.The integrated encoding circuit 19 receives clock signals from a block generator and includes a microprocessor clocked by the oscillator block or a wired logic to send in series on line 18 the binary word corresponding to the symbol of the key pressed so that this word is processed by the processing unit 29. The processing unit 29 can be a microcontroller clocked at a frequency of the order of 32 KHz supplied by a quartz oscillator block (not shown). He is at note that the oscillator block of the integrated encoding circuit 19 and that of the processing 29 can be the same as that of the timepiece circuit 9 of the watch.

Le circuit intégré d'encodage 19 offre l'avantage de n'avoir que deux pistes métalliques 17, 18 de communication entre le clavier 13 ou 23 et l'intérieur du boítier 2 et de permettre ainsi un renforcement mécanique desdites pistes. Toutefois, le clavier 13 ou 23 n'étant soumis à aucune contrainte de traction, il est parfaitement possible de faire l'économie du circuit intégré d'encodage 19 en reliant toutes les pistes 20 des contacteurs 14a directement à l'unité de traitement 20.The integrated encoding circuit 19 offers the advantage of having only two tracks metallic 17, 18 communication between the keyboard 13 or 23 and the inside of the housing 2 and thus allow mechanical reinforcement of said tracks. However, the keyboard 13 or 23 not being subjected to any tensile stress, it is perfectly possible to save on the integrated encoding circuit 19 by connecting all the tracks 20 of the contactors 14a directly to the processing unit 20.

On observera également que la bande supérieure 31 en matériau caoutchouteux peut se prolonger un peu au-delà du franchissement de la carrure 12 et constituer avec la bande inférieure 33 un joint d'étanchéité à ce niveau là.It will also be observed that the upper strip 31 made of material rubbery can extend a little beyond the crossing of the middle 12 and constitute with the lower strip 33 a seal at this level.

Les exemples qui viennent d'être décrits peuvent faire l'objet de nombreuses variantes de réalisation à la portée de l'homme de métier sans sortir du cadre de la présente invention.The examples which have just been described can be the subject of numerous variant embodiments within the reach of those skilled in the art without departing from the scope of the present invention.
