Abstract
Description
La présente revendication concerne un dispositif permettant d'effectuer des sommes de manière automatique. The present claim relates to a device for making sums automatically.
Le calcul des points d'une copie corrigée se fait à la main, ce qui peut engendrer des erreurs et une pénibilité lors de la correction des examens. Les calculatrices classiques permettent d'effectuer des sommes, mais cela implique d'appuyer sur la touche «+» après chaque nombre tapé. De même, la saisie des nombres décimaux implique la pression d'au moins trois touches engendrant une perte de temps et un risque d'erreur. The calculation of the points of a corrected copy is done by hand, which can lead to errors and difficulty in the correction of exams. Conventional calculators allow sums to be made, but this implies pressing the "+" key after each number entered. In the same way, the entry of the decimal numbers implies the pressure of at least three keys generating a loss of time and a risk of error.
Le dispositif selon l'invention permet de palier à ces inconvénients. Il est composé selon une première caractéristique d'un boîtier, sur lequel repose un clavier numérique ainsi qu'un afficheur. Ce dispositif permet de calculer et d'afficher une somme. Le principe consiste à cumuler le nombre tapé au clavier avec le nombre précédent sans avoir à appuyer sur la touche « + ». Les nombres qui peuvent être des nombres décimaux sont prédéfinis à l'avance et affichés sur le clavier. L'utilisateur peut ainsi taper un nombre décimal en une seule pression évitant ainsi les pertes de temps et les risques d'erreurs liés à la frappe sur un clavier. The device according to the invention overcomes these disadvantages. It is composed according to a first characteristic of a housing, on which rests a keypad and a display. This device makes it possible to calculate and display a sum. The principle is to accumulate the number typed on the keyboard with the previous number without having to press the "+" key. Numbers that can be decimals are predefined in advance and displayed on the keyboard. The user can thus type a decimal number in a single press thus avoiding the waste of time and the risks of errors related to the typing on a keyboard.
Selon les modes particuliers de réalisation : le boîtier est rectangulaire d'une épaisseur maximum d'un centimètre la face avant du boîtier est rectangulaire et prédécoupée les touches du clavier sont disposées en saillies sur la face avant du boîtier prédécoupé à cet effet l'afficheur est disposé à l'avant des touches du clavier, sur la face avant du boîtier prédécoupé à cet effet le circuit imprimé ainsi que ses composants sont disposés sous le clavier à l'intérieur du boîtier la face arrière du boîtier est rectangulaire et sans aucun pré découpage. Elle vient fermer le boîtier. According to the particular embodiments: the housing is rectangular with a maximum thickness of one centimeter the front face of the housing is rectangular and pre-cut the keys of the keyboard are arranged protruding on the front of the housing precut for this purpose the display is disposed at the front of the keyboard keys, on the front of the precut housing for this purpose the printed circuit and its components are arranged under the keyboard inside the housing the rear face of the housing is rectangular and without any pre cutting. She comes to close the case.
Les dessins annexés illustrent l'invention : La figure 1 représente le dispositif de l'invention en face avant avec un clavier 24 touches. La figure 2 représente le dispositif de l'invention en face avant avec un clavier 25 touches.40 Dans la forme de réalisation selon la figure 1 ou 2, l'additionneuse comporte un boîtier [1], un afficheur en partie supérieure [2], et un clavier en partie centrale [3]. La taille du boîtier varie entre 10 et 12 cm pour la longueur, 6 et 8 cm pour la largeur, 0,5 et 1 cm pour l'épaisseur. L'intérieur du boîtier comporte un circuit imprimé, des composants électronique, l'alimentation (entre 1,5 et 6 V), l'afficheur. Les faces avant et arrière du boîtier sont vissées entre elles. La taille de l'afficheur varie entre 7 et 10 cm pour la longueur et 1 et 2 cm pour la largeur. Il est de type LCD. The attached drawings illustrate the invention: FIG. 1 represents the device of the invention on the front face with a 24-key keyboard. FIG. 2 shows the device of the invention on the front face with a 25-key keyboard. In the embodiment according to FIG. 1 or 2, the adder comprises a housing [1], a display at the top [2] , and a keyboard in the central part [3]. The size of the case varies between 10 and 12 cm for the length, 6 and 8 cm for the width, 0.5 and 1 cm for the thickness. The inside of the case includes a printed circuit board, electronic components, the power supply (between 1.5 and 6 V), the display. The front and back of the housing are screwed together. The size of the display varies between 7 and 10 cm for the length and 1 and 2 cm for the width. It is LCD type.
La taille du boîtier varie entre 7 et 9 cm pour la longueur et 7 et 10 cm pour la largeur. Chaque touche est sérigraphiée avec les nombres suivants et caractères suivants : 0,25 0,50 0,75 1,00 1,25 1,50 1,75 2,00 2,25 2,50 2,75 3,00 3,25 3,50 3,75 4,00 4,25 4,50 4,75 5 C CE On/Off. La touche C annule la dernière frappe. La touche CE remet l'affichage à zéro. La touche On/Off allume ou éteint l'additionneuse. La disposition varie selon le nombre de touches. Ces variantes sont définies dans la figure 1 [3] ou la figure 2 [3]. The size of the case varies between 7 and 9 cm for the length and 7 and 10 cm for the width. Each key is silk-screened with the following numbers and characters: 0.25 0.50 0.75 1.00 1.25 1.50 1.75 2.00 2.25 2.50 2.75 3.00 3, 25 3.50 3.75 4.00 4.25 4.50 4.75 5 C CE On / Off. The C key cancels the last keystroke. The CE key resets the display. The On / Off key turns the adder on or off. The layout varies depending on the number of keys. These variants are defined in Figure 1 [3] or Figure 2 [3].
Le dispositif selon l'invention est destiné aux enseignants lors des corrections de copies d'une classe ou lors des corrections d'examens. The device according to the invention is intended for teachers when correcting copies of a class or during exam corrections.
