Abstract

PURPOSE: To make the size of device small, by providing two functions of numerical input keys and display elements displaying the result of operation, for the numeric keys.
CONSTITUTION: In case of calculation of 123×4=492, numeric keys are sequentially depressed as 1, 2, 3, function key × is depressed next, numeric key 4 is depressed, and finally equal key = is depressed. Then, operation is made at the central controller CPU with the key output, and the result of calculation is output from CPU to the display register DM, and display is made from the upper rank digit to the numeric key having the display function. Next, this numeric key 4 is shifted into vanish with the controller CPU, and the next numeric key 9 is displayed with illumination. Further, the numeric key 9 is shifted with CPU into vanish to display the numeric key 2 with illumination.
