ABSTRACT:
There is provided a communicating apparatus such as a television telephone having the absence recording function which can communicate either one or both of an image signal and a voice signal. The apparatus comprises: a memory such as a disk-shaped recording medium to store the voice signal and image signal so as to be concerned with each other; a judgement circuit to discriminate whether or not a personal code number which is input from a destination partner side through a public telephone line coincides with the ID number recorded on the memory; a transmitter to transmit the voice signal and the image signal stored in the memory as a pair to the line in accordance with the result of the discrimination of the judgement circuit; and a reading circuit to read out the voice signal and the image signal from the memory. After the transmitter transmitted the image signal, it transmits the voice signal. Thus, the subscriber can listen to the partner's voice while observing the still image by inputting the correct personal code number to the TV telephone.
