ABSTRACT:
An automatic telephone answering device having a conversation recording function has at least one tape cassette operative in a telephone answering mode to reproduce an outgoing message to a calling party and to record incoming messages in a standard manner, in response to an incoming call when the cassette is in a first position in the device. When the cassette is removed from the device, inverted reinserted so that the cassette is in a second position, the device is automatically operative in a conversation recording mode to record conversations between the calling and called parties. If more than a predetermined period of time elapses between the end of a conversation and the start of the next conversation or turning over of the cassette to provide a standby mode, an alarm is triggered.
