Abstract:
A communication apparatus comprising:a transmitter for transmitting a first signal representing information to be transmitted to a receiving side communication apparatus via a telephone line connected therebetween;a memory for storing an identification number which identifies the receiving side communication apparatus and the first signal, the memory further including a first storage unit for storing the identification number and a second storage unit for storing the first signal, wherein the identification number and the first signal relate to each other;a sensor for sensing an incoming second signal transmitted from the receiving side communication apparatus; anda controller for controlling the transmitter so that when the incoming second signal is not sensed by the sensor within a predetermined time, the transmitter retransmits the first signal stored in the second storage unit to the receiving side communication apparatus so as to correspond to the identification number of the receiving side communication apparatus,wherein retransmission of the first signal stored in the second storage unit is performed after the communication apparatus completes a communication session for transmission with the receiving side communication apparatus and the telephone line is released, thereby automatically reminding the receiving side communication apparatus of a reply to the previous transmission.
