Abstract

PURPOSE: To make it possible to confirm easily switching of modes, by detecting and displaying switching of modes and by holding mode display until the key is input from a key input device.
CONSTITUTION: In the electronic desk calculator having plural modes, detector 6 can switch output signals of mode system display signal generation parts 3, 4, and 5 by mode switching switch 2. Then, detection circuit 6 detects mode switching of switch 2 and displays the mode on display unit 1, and simultaneously, display of the mode is held until the key is input from key input device 7. As a result, it can be confirmed easily by unit 1 whether mode switching is performed accurately or not.
