发明名称 TELEPHONE ANSWERING DEVICES
摘要 A device for automatic telephone answering which is adapted to play over a text which has been pre-recorded by the user of the device and which can also replay upon command via telephone, messages recorded by callers when actuated by code impulses transmitted through the telephone line. In particular, the present system permits stored messages to be played back and erased by remote control. To effect these functions cyclically the system combines a magnetic recording unit with mechanical drive means in an integrated constructional assembly. In this system, the answering unit and associated means effecting recording and drive thereof are combined into an integrated assembly with control means.
