Single frequency remote control of telephone answering device accomplishes several functions dependent on the present state of the device

Claim 1

An automatic telephone answering apparatus comprising: (a) a single magnetic tape having an outgoing message region for recording an outgoing message to be played to a calling party and an incoming message region for sequentially recording incoming messages from the calling party, said outgoing message region being located at a beginning of said single magnetic tape and said incoming message region being located at an end of said outgoing message region; (b) a magnetic head for recording a signal on said magnetic tape and reproducing the signal therefrom; (c) record mode means for causing said magnetic head to record the signal on said magnetic tape and forwarding said magnetic tape at a normal speed; (d) play mode means for causing said magnetic head to reproduce the signal from said magnetic tape and forwarding said magnetic tape at the normal speed; (e) fast forward mode means for fast forwarding said magnetic tape; (f) rewind mode means for rewinding said magnetic tape; (g) position detecting means for detecting a position of said magnetic tape; (h) signal detecting means for detecting a remote control signal sent through telephone lines; and (i) control means for selectively operating said play mode means, said record mode means, said fast forward mode means and said rewind mode means in response to said signal detecting means, said apparatus further comprising: (j) means for fast forwarding said magnetic tape to a first position when a first remote control signal sent through the telephone lines is detected during a first play mode for playing a first outgoing message prerecorded on said magnetic tape upon reception of an incoming message, and thereafter for setting said apparatus in a second play mode; (k) means for rewinding said magnetic tape to a second position upon detection of a second remote control signal sent through the telephone lines during the second play mode, and thereafter setting said apparatus in a record mode; (l) means for recording a second outgoing message sent through the telephone lines in the record mode on said outgoing message region of said magnetic tape; and (m) means for rewinding said magnetic tape to the second position when said magnetic tape reaches the end of said outgoing message region in the record mode, and for setting said apparatus in a third play mode from the second position; (n) whereby a position of said magnetic tape upon detection of a third remote control signal sent through the telephone lines during the third play mode is detected by said position detecting means as a third position and stored.

Claim 8

An apparatus according to claims 1 or 6, wherein the second remote control signal comprises a continuous signal, said magnetic tape being rewound to the second position upon detection of the continuous signal for longer than a predetermined period of time.
