In FIG. 3, first, in order to perform a certain calculation using the calculation function of the telephone 1, a numerical value to be calculated is inputted from the telephone number button group 10 in step 5lot. For this reason, the CPU
II checks whether this input data is numerical data in step 5102, and if it is numerical data, it checks in step 5103.
This value is stored in the memory 15. At the same time, the numerical value input in step 5104 is displayed and output to the display 13 via the display driver 12.

When the input of the first numerical value to be calculated is completed, one of the calculation buttons 14 (=, +, -, x, 10, etc.) is input. In this case, since no numerical value is input in step 5102, the process advances to step 5105, where it is checked whether or not the "=" button is input. If the calculation value input has not yet been completed, the "=" button is not input, but the calculation symbol key is input. Therefore, in this case, the process advances from step 5105 to steps 5106 and 5107, the corresponding calculation data is read out from the memory 15, the CPU 5 performs calculations within the range that can be performed at this point, and the calculation results are stored in step 3108. Write to memory 15, followed by step 510
At step 9, the calculation result is displayed on the display 13, and the process returns to step 5101.

In this way, from step 5lot to step 510
After repeating the process in step 9 several times, when the "=" button is pressed, the process advances from step 5105 to step st to, reads out the numerical value stored in the memory 15, and returns to step 5.
The final calculation is performed with ill. In the following step 5112, the final calculation result is displayed on the display 14 via the display driver 13. Then, in step 5113, the DTMF generator 16 is started, and the series of calculation processes up to now or the final calculation result is converted into a DTMF signal, and step Sl
A DTMF signal corresponding to the calculation result converted in step 14 is sent to the telephone line 3.

This DTMF signal is sent to the connected telephone 2 via the telephone line 3, and therefore, the connected telephone 2 (in communication with telephone 1) receives this DTMF signal via the telephone line 3 as in step S201. become. The telephone 2 converts this received DTMF signal into a DTMF signal in step 5202.
The detection circuit 17 converts it into the corresponding 4-bit code data shown in FIG. As explained above, according to this embodiment, the calculation result by the telephone 1 is directly sent from the telephone 1 via the telephone line 3 to the telephone 2, which is the desired transmission destination, and is made visible on the display 13. It becomes possible to display.
