Abstract

PURPOSE:To allow the opposite party to see the display of a normal electronic calculator easily by providing a circuit for display drive inversion between the storage part and display of the electronic calculator together with a key top therefor, and inverting the direction of displayed characters while the direction of the electronic calculator is unchanged. CONSTITUTION:When inputted with a ten-key 4 and an arithmetic key 5 after a power supply switch 3 is turned on, a figure processed and the result is displayed on the display 2. The display drive inverting circuit is provided between the display 2 and an incorporated display storage circuit part which is not shown in a figure, and the display inversion key RE6 is provided on an operation surface. When the display inversion key 6 is pressed, data stored in the display storage circuit is inverted by the display drive inverting circuit and displayed on the display 2. Then, the figure and symbol obtained by inverting the direction of the normal number is displayed on the display 2 and the opposite party recognizes the display easily with the direction of the calculator unchanged. This is suitable for letting a customer know a numeral value during a business talk.

Conventionally, calculators that perform various calculations by operating a keyboard placed on the palm of the hand, so-called electronic tabletop calculators (1V desks), have been used in various configurations. This makes it possible to easily perform four-digit to 12-digit arithmetic operations and program calculations. Jin's calculator usually had a keyboard and a display, and the input data from the keyboard was displayed on the display, as well as the calculation results, so that they could be read visually. In this conventional calculator, the numbers or characters displayed by the display are always directed toward the operator and can only be read by the operator. Therefore, when a salesman and a customer have face-to-face business negotiations, etc., the salesman inputs predetermined data on the keyboard and calculates the results for expenses, estimates, appraisals, etc. Since numerical values or characters are displayed on a display, it is necessary to either flip the calculator over and have the customer read it, or to rewrite the indicated value on a piece of paper and hand it to the customer, which is a hassle during business negotiations. It was something new.
