Abstract
PURPOSE: To make sure of arithmetic without need for a shift in operator's viewpoint, by displaying a memory mark equivalent to each memory at every time of the operation of a key group relating to memories.
CONSTITUTION: X register 1 is stored with display numeric data, decimal-point data, key codes and codes, and its output 12 is led to segment driver circuit SD9 and decision circuit JD25. Further, Z register 2 is stored with positions of memory marks and numeric data positions of register 1 correspond to the contents of the memory mark memory unit of register 2 (a); and they are led out of respective registers at the same timing and output 14 of register 2 is inputted to memory mark driver circuit MD10 and selector MP5. When a display instruction is sent out from ROM3, output 27 is energized via instruction decoder ID6 to drive SD9, MD10 and digit- signal driver circuit DD11, so that the display unit performs display as shown by (b).
