Abstract
A record/play unit and a tape controller in an automatic telephone answering device with a paging function that sets an incoming message tape in a record mode in response to a beep tone generated upon completion of the sending of a first, normal, outgoing message and a second outgoing message for providing a paging procedure to a caller when an incoming message is not recorded by the caller after the beep tone is generated. The controller thereafter drives an engaging section in response to a special code sent by the calling party. The engaging section temporarily disengages the device from the telepone lines and then engages the device with the telephone lines again. Subsequently, a DTMF oscillator is operated to dial a prestored telephone number.
