Abstract
PURPOSE: To improve the value of use of a calculator by providing an auxiliary display part, which displays numeric information led from an operation register or a memory into a storage device, besides a display part which displays numeric information led into a display register.
CONSTITUTION: Main display part 9 and auxiliary display part 10 are arranged on liquid crystal display panel 8 of an electronic desk calculator which displays numeric information dipendently upon a liquid crystal display, and numeric information led into display register 1 is desplayed on main display part 9, and numeric information existing in storage device 5 other than register 1 is displayed on display part 10. Size of display characters and deflecting plates 11 and 12 arranged in front are different in display parts 9 and 10 to prevent confusion of display characters. Digit terminals connected commonly correspondingly to respective segment electrodes constituting respective digits of display parts 9 and 10 and segment terminals connected independently to common electrodes respectively are provided, and the output of a single decoder of display driving circuit 7 connected to device 5 is applied to segment terminals, and timing signals are applied to respective digit terminals.
