Remote-controllable automatic telephone answering device

Claim 2

In an automatic telephone answering device which sends out the contents of at least one recorded message to a calling party at a remote place upon arrival of a remote control signal from said calling party after the detection of a ringing signal sent over a communication circuit, the improvement comprising: an oscillator for generating a low-frequency signal; means responsive to a first-received remote control signal to record the low-frequency signal, in a second channel developed on the same recording tape as a first channel for recording messages, in a forward direction for a predetermined period of time; a plurality of magnetic heads respectively corresponding to said first and second channels on said recording tape; a recording tape rewinding mechanism; and control means for controlling said recording tape rewinding mechanism of said device after completion of the recording of the low-frequency signal to rewind the recording tape so that said magnetic heads corresponding to said first channel and said second channel are opposite a position on said recording tape beyond the recorded position of said low-frequency signal but short of the end of a last recorded message.

Claim 3

An automatic telephone answering device according to claim 1, including means for permitting the first remote control signal to be received during sending out of an answering message after said detection of the ringing signal.

Claim 4

In an automatic telephone answering device which sends out the contents of at least one recorded message to a calling party at a remote place upon arrival of a remote control signal from said calling party after the detection of a ringing signal sent over a communication circuit, the improvement comprising: an oscillator for generating a low-frequency signal; means responsive to a first-received remote control signal to record the low-frequency signal, in a second channel developed on the same recording tape as a first channel for recording messages, in a forward direction for a predetermined period of time; a plurality of magnetic heads respectively corresponding to said first and second channels on said recording tape; a recording tape rewinding mechanism; first control means for controlling said recording tape rewind mechanism of the device after completion of the recording of the low-frequency signal to rewind the recording tape so that said magnetic heads corresponding to said first channel and said second channel are opposite a position on said recording tape beyond the recorded low-frequency signal but short of the end of a last recorded message; second control means for controlling the recording tape rewind mechanism to continue the tape rewinding operation for further rewinding the tape for sending out a message previously recorded in response to reception of the remote control signal when the recording tape has reached the abovesaid position, and third control means for controlling the recording tape rewind mechanism to rewind the recording tape to the position short of the end of the last recorded message when the low-frequency signal is reproduced from the second channel during reproducing of the message.

Claim 5

In an automatic telephone answering device which sends out the contents of at least one recorded message to a calling party at a remote place upon arrival of a remote control signal from said calling party after the detection of a ringing signal sent over a communication circuit, the improvement comprising: an oscillator for generating a low-frequency signal; means responsive to a first-received remote control signal to record the low-frequency signal, in a second channel developed on the same recording tape as a first channel for recording messages, in a forward direction for a predetermined period of time; a plurality of magnetic heads respectively corresponding to said first and second channels on said recording tape; a recording tape rewinding mechanism; first control means for controlling said recording tape rewind mechanism of the device after completion of the recording of the low-frequency signal to rewind the recording tape so that said magnetic heads corresponding to said first channel and said second channel are opposite a position on said recording tape beyond the recorded low-frequency signal but short of the end of a last recorded message; second control means for controlling the recording tape rewind mechanism to continue the tape rewinding operation for further rewinding the tape for sending out a message previously recorded in response to reception of the remote control signal when the recording tape has reached the abovesaid position, and third control means for controlling the recording tape rewind mechanism to rewind the recording tape to the position short of the end of the last recorded message when the low-frequency signal is reproduced from the second channel during reproducing of the message.

Claim 6

An automatic telephone answering device according to claim 3, including means for permitting the first remote control signal to be received during sending out of an answering message after said detection of the ringing signal.

Claim 7

In an automatic telephone answering device which sends out the content of at least one recorded message to a calling party at a remote place upon arrival of a remote control signal after the detection of a ringing signal sent over a communication circuit, the improvement comprising: an oscillator for generating a low-frequency signal; means responsive to a first-received remote control signal to record the low-frequency signal, in a second channel developed on the same recording tape as a first channel for recording messages, in a forward direction for a predetermined period of time; a plurality of magnetic heads respectively corresponding to said first and second channels on said recording tape; a recording tape rewinding mechanism; message reproducing means for controlling said recording tape rewind mechanism after completion of the recording of the low-frequency signal to rewind the recording tape for reproducing the content of the recorded message; and control means for controlling the recording tape rewind mechanism to rewind the recording tape so that said magnetic heads corresponding to said first channel and said second channel are opposite a halt position on said recording tape beyond the recorded low-frequency signal but short of the end of the recorded message when the low-frequency signal is reproduced from the second channel during said reproducing.

Claim 8

In an automatic telephone answering device which sends out the content of at least one recorded message to a calling party at a remote place upon arrival of a remote control signal after the detection of a ringing signal sent over a communication circuit, the improvement comprising: an oscillator for generating a low-frequency signal; means responsive to a first-received remote control signal to record the low-frequency signal, in a second channel developed on the same recording tape as a first channel for recording messages, in a forward direction for a predetermined period of time; a plurality of magnetic heads respectively corresponding to said first and second channels on said recording tape; a recording tape rewinding mechanism; message reproducing means for controlling said recording tape rewind mechanism after completion of the recording of the low-frequency signal to rewind the recording tape for reproducing the content of the recorded message; and control means for controlling the recording tape rewind mechanism to rewind the recording tape so that said magnetic heads corresponding to said first channel and said second channel are opposite a halt position on said recording tape beyond the recorded low-frequency signal but short of the end of the recorded message when the low-frequency signal is reproduced from the second channel during said reproducing.

Claim 9

An automatic telephone answering device according to claim 5, wherein said control means includes a plunger for stopping the recording tape at the halt position.
