PURPOSE: To output a storage part address and a display data from the same terminal, by time-dividing a display data time and a storage part access time, in a telephone terminal set having plural processing parts, a common storage part and a display part.
CONSTITUTION: A telephone set circuit 1 is provided with 2 groups of processing parts 2, 3, a storage part 4 used in common by the processing parts 2, 3, a dial pulse oscillating circuit 5, a keying circuit 6, a display part 7, a data modulating and demodulating circuit 8, a data inputting and outputting circuit 9, etc. The processing part 2 energizes each digit of the display part 7 for a prescribed period to subsequently access the storage part 4 only for the same period. The processing part 3 is in succession, allowed to access the storage pary 4 only for the same period. In this way, the processing parts 2, 3 are capable of transferring a comparatively large quantity of data to the storage part to improve processing effect.
