Abstract

A calculator for converting Euros into a national currency is integrated into a watchcase and keys corresponding to numbers (2) and to operations such as Clear, Decimal and Convert (4,5,6) are located around the dial periphery. After conversion the result is displayed in a slot (3) on the watch dial. The function may be extended to conversions in the opposite sense by adding additional operating keys and to devices such as portable telephones

Description

- 1-- 1-

La présente invention concerne un clavier numérique.  The present invention relates to a digital keyboard.

Le passage à la monnaie unique européenne en 2002 va poser le problème de la conversion des prix exprimés en euros. Il se passera en effet une longue période avant que chacun compte en euros. Pour effectuer une conversion, il est avantageux d'avoir recours à une calculatrice mais il faut alors sortir celle-ci de sa poche et la tenir dans une main pendant que l'on appuie sur les touches en se servant de l'autre main. Ceci est loin d'être pratique, surtout si l'on est amené à recommencer fréquemment l'opération, Io dans un magasin par exemple. Le problème à résoudre consiste donc à trouver un moyen de rendre plus pratique l'utilisation régulière d'une  The changeover to the single European currency in 2002 will pose the problem of converting prices expressed in euros. There will indeed be a long period before everyone counts in euros. To carry out a conversion, it is advantageous to use a calculator but you must then take it out of your pocket and hold it in one hand while you press the keys using the other hand. This is far from practical, especially if you have to repeat the operation frequently, Io in a store for example. The problem to be resolved therefore consists in finding a way to make the regular use of a

calculatrice pour effectuer la conversion.  calculator to perform the conversion.

La présente invention concerne l'utilisation d'une calculatrice intégrée à une montre-bracelet et dédiée à la conversion des euros, caractérisée en ce que les touches du clavier de cette calculatrice sont réparties sur le  The present invention relates to the use of a calculator integrated into a wristwatch and dedicated to the conversion of euros, characterized in that the keys of the keyboard of this calculator are distributed over the

pourtour de la montre, en regard des chiffres des heures correspondants.  around the watch, next to the corresponding hour figures.

L'intérêt d'intégrer la calculatrice à une montre-bracelet réside dans le fait que celle-ci est alors disponible en permanence, sans que l'on ait besoin de la sortir de la poche et de la tenir dans une main. Il existe certes des montres dotées d'une calculatrice mais leur petit clavier juxtaposé au boîtier de la montre rend leur utilisation délicate. L'invention propose donc de palier cette difficulté et de rendre le clavier plus facile d'emploi dans le cas  The advantage of integrating the calculator into a wristwatch lies in the fact that it is then permanently available, without the need to take it out of the pocket and hold it in one hand. There are certainly watches equipped with a calculator but their small keyboard juxtaposed with the watch case makes their use delicate. The invention therefore proposes to overcome this difficulty and to make the keyboard easier to use in the case

particulier de la conversion des euros.  especially the conversion of euros.

La solution consiste d'une part à répartir les touches sur le pourtour de la montre, ce qui a pour effet de les espacer, et d'autre part à placer les touches représentant les nombres de 1 à 9 en regard de la position des chiffres des heures correspondants sur le cadran de la montre, ce qui permet à l'utilisateur de les trouver facilement. Quant au zéro, il est envisageable selon un mode de réalisation de le positionner en face du chiffre 12, que l'on pourrait d'ailleurs remplacer par un zéro (pour zéro heure). Selon un autre mode de réalisation, la touche zéro est placée en regard du chiffre 10 qui contient déjà un zéro. Il serait alors souhaitable que ce zéro se distingue du 1 qui le précède, par une couleur différente par exemple, afin d'indiquer l'utilisation conventionnelle qui en est faite par la calculatrice. -2- Une calculatrice dédiée à la conversion des euros en monnaie nationale n'a pas besoin d'autant de touches de fonction qu'une calculatrice offrant la gamme des opérations arithmétiques. Il s'agit pour l'utilisateur de la calculatrice, dans le cas général, d'évaluer un prix exprimé en euros en le traduisant en monnaie nationale. La conversion se fait donc dans le sens de l'euro vers la monnaie nationale et non l'inverse. De même, la conversion dans la seule monnaie nationale suffit à l'utilisateur car même s'il se rend à l'étranger, c'est toujours dans sa monnaie nationale et non dans une autre monnaie qu'il souhaitera effectuer la conversion d'un prix en euros. Il faut wo bien voir en effet que le but de la calculatrice dédiée n'est pas d'effectuer des opérations croisées de change mais de permettre à l'utilisateur de se faire une idée précise d'un prix exprimé en euros. Pour cela, il a seulement besoin de revenir dans sa monnaie nationale car c'est la monnaie dans laquelle il compte, celle qui lui offre des repères. s5 Si l'on accepte cette façon de voir, la calculatrice dédiée peut se contenter de quatre touches de fonction en plus des 10 touches représentant des nombres et le zéro: une touche marche-arrêt, une touche pour la virgule, une touche de conversion et une touche d'effacement. Si l'on situe la touche marche-arrêt sur le côté de la montre, près de la molette de réglage de l'heure par exemple, les trois touches de fonction restantes peuvent être placées dans l'intervelle entre le 9 et le 12 ou entre le 10 et le 1  The solution consists on the one hand in distributing the keys around the periphery of the watch, which has the effect of spacing them out, and on the other hand in placing the keys representing the numbers from 1 to 9 opposite the position of the numbers corresponding hours on the watch face, making it easy for the user to find them. As for the zero, it is possible according to one embodiment to position it opposite the number 12, which could moreover be replaced by a zero (for zero hours). According to another embodiment, the zero key is placed opposite the number 10 which already contains a zero. It would then be desirable for this zero to be distinguished from the 1 preceding it, by a different color for example, in order to indicate the conventional use made of it by the calculator. -2- A calculator dedicated to the conversion of euros into national currency does not need as many function keys as a calculator offering the range of arithmetic operations. It is for the user of the calculator, in the general case, to evaluate a price expressed in euros by translating it into national currency. The conversion is therefore done in the direction of the euro towards the national currency and not the reverse. Similarly, the conversion into the national currency alone is sufficient for the user because even if he goes abroad, it is always in his national currency and not in another currency that he will wish to carry out the conversion of a price in euros. It must be clearly seen in fact that the purpose of the dedicated calculator is not to carry out cross exchange operations but to allow the user to have a precise idea of a price expressed in euros. For this, he only needs to return to his national currency because it is the currency in which he counts, the one that offers him benchmarks. s5 If we accept this view, the dedicated calculator can be satisfied with four function keys in addition to the 10 keys representing numbers and zero: an on-off key, a comma key, a conversion key and an erase key. If the on / off button is located on the side of the watch, near the time setting wheel for example, the three remaining function buttons can be placed in the range between 9 and 12 or between 10 and 1

selon le choix qui a été fait pour l'emplacement de la touche zéro.  depending on the choice made for the location of the zero key.

Sur un cadran de montre circulaire par exemple, les 10 touches représentant des nombres et le zéro se répartissent sur la circonférence du boîtier, à égale distance les unes des autres et selon un ordre logique. Il est facile de les trouver car chacun sait o se situent les chiffres des heures sur un cadran. Il est également aisé de les actionner car leur espacement est suffisant pour que le doigt ne risque pas d'appuyer sur deux touches à la fois. Sur un boîtier de montre circulaire de 3 cm de diamètre par exemple, les touches seront espacées d'environ 0,75 cm, c'est-à-dire que chaque touche numérique sera située au milieu d'un intervalle d'environ 1,5 cm  On a circular watch dial, for example, the 10 keys representing numbers and the zero are distributed around the circumference of the case, equidistant from each other and in a logical order. It is easy to find them because everyone knows where the hour digits are on a dial. It is also easy to activate them because their spacing is sufficient so that the finger does not risk pressing two keys at the same time. On a circular watch case 3 cm in diameter for example, the keys will be spaced about 0.75 cm apart, that is to say that each numeric key will be located in the middle of an interval of about 1, 5 cm

entre les touches les plus proches.between the nearest keys.

Si l'on estime en revanche que la calculatrice dédiée ne peut pas se contenter d'évaluer seulement un prix exprimé en euros dans une seule monnaie mais qu'elle doit aussi être capable d'effectuer l'opération dans les deux sens et dans plusieurs monnaies nationales, cela reste bien sûr possible mais avec l'inconvénient de devoir ajouter des touches de fonction -3- supplémentaires. Quelle que soit la solution retenue, il faudra que les touches représentant des nombres restent en face de la position des chiffres  If, on the other hand, it is considered that the dedicated calculator cannot be satisfied with only evaluating a price expressed in euros in a single currency, but that it must also be able to carry out the operation in two directions and in several national currencies, this is of course possible, but with the disadvantage of having to add additional function keys. Whichever solution is chosen, the keys representing numbers must remain opposite the position of the numbers.

des heures correspondants.corresponding hours.

Le dispositif selon l'invention s'applique à toutes les montres- bracelets dont le boîtier possède des dimensions suffisantes pour que les touches de la calculatrice puissent être réparties sur son pourtour avec un intervalle convenable, que le boîtier soit circulaire, ovale, carré ou rectangulaire. La seule contrainte à respecter est que l'on repère facilement les touches par io rapport à la position des chiffres des heures. Si c'est le cas, ces chiffres n'ont d'ailleurs même pas besoin d'être inscrits sur le cadran et la calculatrice, fait exceptionnel, peut être utilisée sans que son clavier possède une numérotation apparente tellement la position des chiffres des  The device according to the invention applies to all wristwatches whose case has sufficient dimensions so that the keys of the calculator can be distributed around its periphery with a suitable interval, whether the case is circular, oval, square or rectangular. The only constraint to be observed is that the keys are easily identified by io relative to the position of the hour digits. If this is the case, these figures do not even need to be entered on the dial and the exceptional calculator can be used without its keyboard having an apparent numbering so much the position of the digits

Cette particularité peut être intéressante pour d'autres applications, telles que les claviers numériques servant à composer un code afin d'ouvrir la porte d'un immeuble ou de se servir d'un distributeur de billets par exemple, car le clavier selon l'invention est utilisable même si les touches  This feature can be interesting for other applications, such as keypads used to dial a code to open the door of a building or to use an ATM for example, because the keyboard according to the invention can be used even if the keys
