Abstract
PURPOSE: To realize a small sized calculator which can be used for multipurpose, by selecting and displaying any one of the part or result of operation on the way of input numeral equation easily.
CONSTITUTION: The result of operation from CPU is fed to the switching terminal A of the switch SW from a memory unit D1 as display information, and the display information in a memory unit D2 is fed to the switching terminal B, and either one is selected and picked up and displayed on a display section DSP from an OR gate OR1. Independently of a switch SW, when an equal key K4 is depressed, the result of operation from the memory unit D1 is always fed to the display section DSP from the OR gate OR1 with the Q output from FFF1 set with the output of the key K4.
