ABSTRACT:
An automatic telephone answering and recording device is capable of selecting, in accordance with a length of time for pushing an "absent" button, either the case where the device operates automatically after a first or a second incoming ringing signal or the case where the device does not constitute the closed circuit of a telephone line while an answer tape is driven, by one round, for confirmation and the device merely returns a ringing back tone to a calling party. Also, the device adopts a control system controlled by the program stored in a microcomputer thereby to distinguish two cases each of which is formed dependent on a length of time for pushing the "absent" button, respectively.
