Abstract
Abstract A telephone automatic answering device including provision for remotely controlling said device to cause playback of messages and selective rewinding of a message recording tape. The device includes an answer tape on which a prerecorded answer may be placed, and a message tape which receives and reproduces messages left by callers. The subscriber may initiate playback of the message tape by causing a remote signal to be applied over the telephone line. The answering device picks up the remote signal and rewinds the message tape a predetermined amount. The subscriber then hears the recorded messages and knows immediately if it is necessary to rewind the tape an additional amount. If the subscriber wants to rewind the tape an additional amount, he causes the remote signal to be sent again over the telephone line. The message tape then rewinds for the duration of the latter remote signal. Playback occurs immediately following rewinding and stops when the recorded remote signal arrives at the playback head of the message tape.

Claim 1
Independent Claim
204 words
A remote controllable automatic telephone answering device adapted to be connected to a telephone line, said device comprising; an answer tape, means for reproducing an answer prerecorded on said answer tape and sending out said reproduced answer in response to the reception of a calling signal via said telephone line, a message tape, means for recording callers' messages on said message tape when it is unwinding, means for detecting a remote control signal received via said telephone line, first means for rewinding the message recording tape for a fixed time period in response to a first detection of a first said remote control signal and for reproducing any messages on the thus rewound part of said message tape, said fixed time period being independent of the duration of said remote control signal and independent of the amount of tape unwound, second means responsive to a subsequent detection of a second said remote control signal during the reproducing of said messages for rewinding said message tape for a period corresponding to the duration of the second remote control signal and for reproducing any messages on the part of said message tape thus rewound, and means for sending out said reproduced messages via said telephone line.
Claim 2
Dependent Claim
204 words
A remote controllable automatic telephone answering device adapted to be connected to a telephone line, said device comprising; an answer tape, means for reproducing an answer prerecorded on said answer tape and sending out said reproduced answer in response to the reception of a calling signal via said telephone line, a message tape, means for recording callers' messages on said message tape when it is unwinding, means for detecting a remote control signal received via said telephone line, first means for rewinding the message recording tape for a fixed time period in response to a first detection of a first said remote control signal and for reproducing any messages on the thus rewound part of said message tape, said fixed time period being independent of the duration of said remote control signal and independent of the amount of tape unwound, second means responsive to a subsequent detection of a second said remote control signal during the reproducing of said messages for rewinding said message tape for a period corresponding to the duration of the second remote control signal and for reproducing any messages on the part of said message tape thus rewound, and means for sending out said reproduced messages via said telephone line.
Claim 3
Dependent Claim
19 words
A device as claimed in claim 1 wherein said first and second remote control signals have the same frequency.
Claim 4
Dependent Claim
71 words
A device as claimed in claim 1 wherein said first means comprises rewinding means energizable by a signal applied thereto for rewinding said answer tape for the duration of said applied signal, and monostable multivibrator means normally connected between the output of said detecting means and said rewinding means for applying a signal to said rewinding means for said predetermined period when said detecting means detects said first remote control signal.
Claim 5
Dependent Claim
67 words
A device as claimed in claim 3 wherein said second means comprises switching means responsive to the energization of said rewinding means by said monostable multivibrator means for disconnecting said multivibrator means from said output of said detecting means and for connecting said detecting means output to said rewinding means, whereby subsequent outputs from said detecting means energize said rewinding means for the duration of said outputs.
Claim 6
Dependent Claim
52 words
A device as claimed in claim 4 further comprising means for recording said received remote signal onto said message tape, and means responsive to the reproduction of a thus recorded remote signal for stopping said message tape and for reconnecting said monostable multivibrator means back to the output of said detecting means.
