ABSTRACT:
The present invention relates to an automatic telephone answering device with an automatic switching mechanism for switching between an automatic answering mode and a two-way conversation recording mode. When a telephone is put into an off-hook condition for a direct conversation with a calling party while the automatic answering mode is in a standby condition or in operation, such an off-hook condition is detected by a current detector and the conversation is recorded on a recording tape without any limitation of time. When the telephone is put into an on-hook condition during the recording of the conversation, the current detector or a voice signal detector is operated to stop the recording operation, and then the device is automatically brought into a standby condition for the next call.
