PURPOSE:To display a name of a data and rearrange the displayed items optionally by having a means capable of inputting a name of an item separately from a desired formula. CONSTITUTION:An input and output port 4 outputs a strobe signal to a key input device 3, carriers out an input and output of a time data to a clock circuit 13 and further outputs a driving signal to a driving circuit 14 of a buzzer 15. A microprocessor unit 5 outputs a synchronous signal, ON/OFF signals of a display to a display control section 22, and further a back plate signal to a display section. A display control section 2 displays desired characters and symbol on the display section 1. A formula inputted from the key input device 3 is stored in a RAM6, and when inputting a numeric value in an input item correspondingly a variable name, an operated result is displayed on the display section 1. Herein, the formula, an input item name, an output item name can be individually inputted. |
