Patent

CA 2132612

An electronic calculator allows a user to quickly add up change. The user simply pushes one of the coin switches clearly marked to represent a particular coin denomination in order to add up the change. Each time a coin switch is activated, an accumulated sum is incremented by a value associated with the value of the coin denomination represented by the activated coin switch. The accumulated sum is then displayed to the user. If the user depresses the wrong coin switch, an error switch is provided which subtracts the previous entry made from the tabulated sum to arrive at the tabulated sum previous to the depression of the coin switch.

L'invention est un calculateur électronique qui permet à un utilisateur d'effectuer rapidement des additions de monnaie. € cette fin, l'utilisateur n'a qu'à enfoncer l'un des commutateurs de pièce de monnaie à valeur nominale bien indiquée. Chaque fois qu'un commutateur de pièce de monnaie est actionné, une somme cumulative est augmentée d'une valeur égale à la valeur nominale de la pièce de monnaie correspondant au commutateur de pièce de monnaie actionné. La somme cumulative est ensuite affichée. Si l'utilisateur enfonce un commutateur de pièce de monnaie inapproprié, un commutateur de correction soustrait de la somme tabulée la valeur introduite précédemment pour revenir à la somme tabulée avant l'actionnement du commutateur de pièce de monnaie.
