The present invention is directed to enable a car telephone to receive incoming calls and a telephone answering device to be activated even though the ignition key is removed. A housing is fitted onto a car telephone cradle and a handset is placed on the top of the housing. When there is a call, a rotary arm which is coupled to a motor is moved, and a magnet attached to the tip of the rotary arm opens a reed relay, which corresponds to a hook switch to form a loop circuit. Then an outgoing message is transmitted via a speaker, and an incoming message from a caller is recorded via a microphone.
