Problem: Issue :
Rechenhilfe zur Durchführung von Rechenvorgängen mit manueller Eingabe der Operanden und Durchführung der mathematischen Operationen mit Hilfe eines eingebauten elektronischen RechenwerkesCalculation aid for carrying out calculations with manual input of the operands and carrying out the mathematical operations with the help of a built-in electronic calculator
Es ist bekannt, daß zur Ausführung mathematischer Operationen
Taschenrechner/Digitalrechner zur Verfügung stehen, wobei die Eingabe der Operanden über
eine Tastatur erfolgt.It is known that to perform mathematical operations
Calculators/digital calculators are available, with the operands being entered via a keyboard.
Allerdings werden zur Bedienung derartiger Geräte überwiegend beide Hände benötigt, sofern keine geeignete Ablage oder Halterung zur Verfügung steht.However, both hands are generally required to operate such devices unless a suitable storage or holder is available.
Der in Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, bisher keine Rechenhilfe zu besitzen, bei der die Eingabe der Operanden und die Ausführung von mathematischen Operationen über eine Rechenhilfe realisiert wird, für deren Bedienung in jedem Fall nur eine einzige Hand nötig ist, d.h. die Rechenhilfe wird mit derselben Hand bedient, in der die Rechenhilfe gehalten wird. Weiterhin ist die Eingabe über eine übliche Tastatur für spezielle Anwendungen zu kompliziert und aufgrund der vielen Bedienelemente werden Taschenrechner, z.B. beim täglichen Einkauf in Kaufhäusern, gemieden, weil die Bedienung sehr aufwendig ist.The invention specified in claim 1 is based on the problem that there is currently no calculation aid in which the input of operands and the execution of mathematical operations is carried out using a calculation aid that only requires a single hand to operate, i.e. the calculation aid is operated with the same hand in which the calculation aid is held. Furthermore, input via a standard keyboard is too complicated for special applications and, due to the many operating elements, pocket calculators are avoided, e.g. when shopping in department stores every day, because they are very complex to operate.
Lösunq: Dieses Problem wird durch die im Schutzanspruch 1 aufgeführten Merkmale gelöst. Solution: This problem is solved by the features listed in claim 1.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das Festhalten und die Bedienung der Rechenhilfe mit ein und derselben Hand möglich ist und die Operanden durch ein vereinfachtes Eingabeverfahren aus dem begrenzten Vorrat der je nach Anwendung zu verwendenden Grundsymbole durch wiederholtes Betätigen von Bedienelemeten ausgesucht werden.The advantages achieved with the invention are in particular that the calculation aid can be held and operated with one and the same hand and the operands are selected by a simplified input procedure from the limited supply of basic symbols to be used depending on the application by repeatedly pressing control elements.
Dieses vereinfacht die Operandeneingabe zusätzlich enorm.This further simplifies operand input enormously.
Gegenüber herkömmlichen Rechenhilfen werden bedeutend weniger Bedienelemente zur Eingabe der Operanden benötigt.Compared to conventional calculation aids, significantly fewer control elements are required to enter the operands.
Weitere Ausgestaltung der Erfindung: Eine vorteilhafte Ausgestaltung der Erfindung ist in Schutzanspruch 22 angegeben. Die Weiterbildung nach Schutzanspruch 25 ermöglicht es, Geldbeträge vereinfacht über 3 Bedienelemente einzugeben und die Summe der eingegebenen Geldbeträge anzuzeigen. So kann man z.B. im Kaufhaus kontrollieren, welchen Geldbetrag man maximal an der Kasse bezahlen muß. Further embodiment of the invention : An advantageous embodiment of the invention is specified in claim 22. The further development according to claim 25 makes it possible to enter amounts of money in a simplified manner using three control elements and to display the total of the amounts of money entered. In this way, for example, you can check the maximum amount of money you have to pay at the cash register in a department store.
Beschreibung eines Ausführungsbeispiels: Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Description of an embodiment: An embodiment of the invention is shown in the drawings and is described in more detail below.

Die Figur 1 zeigt den Zustand der Rechenhilfe im eingeschaiteten Zustand, bei dem die Rechenhilfe
zur Eingabe bereit ist.
Nun kann der erste Betrag über die Taster T1, T2 und T3 eingegeben werden.Figure 1 shows the state of the calculation aid in the switched on state, in which the calculation aid is ready for input.
Now the first amount can be entered using the buttons T1, T2 and T3.
Das Betätigen des Tasters T3 verändert die Zehn-Pfennig-Stelle derart, daß aus dem Zeichenvorrat 10, 20, 30, 40, 5O1 60, 70, 80, 90 und 00 Pfennig in einer vorgegebenen Reihenfolge der gewünschte Betrag ausgewählt werden kann.Pressing the T3 button changes the ten-pfennig position in such a way that the desired amount can be selected from the character set 10, 20, 30, 40, 50 1 60, 70, 80, 90 and 00 pfennigs in a predetermined order.
Die Figur 2 zeigt die Anzeige nach dreimaliger (oder dreizehnmaliger oder
dreiundzwanzigmaliger usw.) Betätigung des Tasters T3.Figure 2 shows the display after three (or thirteen) times or
pressing button T3 twenty-three times, etc.).
Bei falscher Eingabe müssen bei allenIf the input is incorrect, all
Bedienelementen diese nur solange erneut betätigt zu werden, bis die richtige Zahl erneut im Display erscheint.Control elements only need to be operated until the correct number appears again in the display.

Das Betätigen des Tasters T2 verändert die Eine-DM-Steile derart, daß aus dem Zeichenvorrat 1, 2, 3, 4, 5, 6, 7, 8, 9 und 0 Deutschen Mark in einer vorgegebenen Reihenfolge der gewünschte Betrag ausgewählt werden kann.Pressing the T2 button changes the one-DM position so that the desired amount can be selected from the character set 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 German Marks in a predefined order.
Die Figur 3 zeigt die Anzeige nach viermaliger (oder vierzehnmaliger oder
vierundzwanzigmaliger usw.) Betätigung des Tasters T2.Figure 3 shows the display after four (or fourteen or
pressing button T2 twenty-four times, etc.).

As soon as the desired amount has been entered and no longer needs to be corrected, the
Bedieneiement 4 (T4) betätigt, um diesen Betrag zum Speicherinhalt (zweite Zeile des Displays A1)
zu addieren.
Die Figur 5 stellt die Anzeige nach einmaliger Betätigung des Tasters T4 dar.Control element 4 (T4) is operated to add this amount to the memory content (second line of the display A1).
Figure 5 shows the display after pressing button T4 once.
Die Figur 6 stellt die Anzeige nach der zweimaligen Betätigung des Tasters T4 dar. Hier sollte der eingegebene Betrag zweimal zum Speicherinhalt addiert werden. Das Ergebnis wird sofort in der zweiten Zeile angezeigt.Figure 6 shows the display after pressing the T4 button twice. Here the entered amount should be added twice to the memory contents. The result is immediately displayed in the second line.
Wenn für eine kurze, vorgegebene Zeit keine weitere Betätigung des Tasters T4 erfolgt, ist die Rechenhilfe bereit für die Eingabe eines neuen Betrages.If the T4 button is not pressed again for a short, predefined period of time, the calculator is ready for the input of a new amount.

Durch das Ausschalten der Rechenhilfe wird der Speicherinhalt gelöscht. Nach erneueter Inbetriebnahme gelangt die Rechenhilfe wieder in den in Figur 1 dargestellten Ausgangsbetriebszustand und ist somit bereit für neue Berechnungen.When the calculator is switched off, the memory contents are deleted. After being switched on again, the calculator returns to the initial operating state shown in Figure 1 and is therefore ready for new calculations.
