Electronic calculator with softkey function display.

摘要

An electronic calculator 1 with a display panel 2 and an input keypad of keys 3 arranged close to the display panel 2, with programmable input function (soft keys) displayed on the display panel 2. According to the invention, the alphanumeric information and/or graphics reproduced on the display panel 2, or parts thereof, are logically combined with the soft keys 3 by software-dependent representation of reference lines 4 extending between them on the display panel 2. The result is that the display of the respective soft key function on the display panel 2 does not require any space needed for representing other information items, the logical combination of the soft keys 3 with an alphanumeric display or graphics on the display panel 2 can be directly recognised and points which are very close to one another on the display panel 2 can also be separately selected with the individual soft keys 3.
