Abstract

PURPOSE:To sufficiently assure the confidentiality, even with the absence of receiver, by one storing the data signal and reproducing it as required. CONSTITUTION:The transmitter 2 produces the memory control signal whether or not the necessity of confidentiality of data signal is requested ahead the data transmission. The receiver 11 directly couples it with the printer 16 with no confidentiality based on the memory control signal. Further, if the confidentiality is required, the data signal is outputted to the memory unit 13 via the switch circuit 12. Accordingly, if the data requiring confidentiality is transmitted to a person who is absent, the immediate print out of data signal can be avoided. The memory unit 13 is magnetic tape etc. and the confidentiality can more increased by cryptogram set between specific personnels.
