置。 Connect the telephone in parallel with one telephone line,
An answering machine circuit for sending a response message to a caller via a telephone line in the answering machine used and recording a business message sent from the caller, and a caller. C that puts the telephone line on-hook and detects the CPC signal generated by the exchange.
A PC detection circuit, an off-hook detection circuit that detects and outputs a change in voltage between the telephone line due to off-hook of the telephone, and an off-hook detection circuit that controls the answering machine circuit upon receiving the output of the CPC detection circuit, and cues the answering message. After that, the connection with the telephone line is opened and put into a standby state, and when the output of the off-hook detection circuit is received, the answering machine circuit is controlled, and after the connection with the telephone line is opened, the head of the response message is sent. The CPC detection circuit detects a CPC signal and applies an output to the off-hook detection circuit to prevent the off-hook detection circuit from operating for a certain period of time. Answering machine.
