Abstract
Abstract A remote control system and apparatus for an automatic telephone answering and recording apparatus comprises: means operating to render the answering and recording apparatus into a remotely operable state only in the case where signals corresponding to numerals of any number of digits previously set on the apparatus side are applied thereto from a remote point, through a telephone line, in the specific sequence, and at intervals within a specific period; mode control means for placing the appartus in a state for an operational mode according to the signals of the digits when, after the operation of the first named means, the digit signals are applied singly; and means for changing the apparatus to the mode corresponding to a specific mode control signal from the mode control means and to a stop signal recording mode in accordance with whether the output duration time of the mode control signal is shorter or longer than a predetermined time period.

A remote control system for an automatic telephone answering and recording apparatus which includes first means for recording on and reproducing from a first cassette tape an answering statement, and second means for recording on and reproducing from a second cassette tape incoming messages by callers; said system comprising: a. answering means responsiVe to an incoming call arriving through a telephone line from a caller for automatically operating said first means to reproduce the answering statement previously recorded on said first cassette tape and for sending the statement through the telephone line toward the caller; b. incoming message recording means responsive to completion of the reproduction of the answering statement by said first means for operating said second means to record on the second cassette tape incoming messages sent by the caller through the telephone line; c. generating means for generating a plurality of kinds of pair tones comprising low tones and high tones; d. detecting means responsive to a set of pair tones selected from the kinds of pair tones which are generated in sequence by said generating means and sent through the telephone line for producing a first control voltage only when the set of pair tones coincide with a predetermined set of pair tones; e. first control means responsive to the first control voltage for driving said second means to rewind the second cassette tape; f. second control means responsive to stopping of the rewinding of the second cassette tape for driving said second means to reproduce the incoming messages; after said detecting means produced the first control voltage, said detecting means producing a second control voltage in response to first digital component pair tones of the set of pair tones which first digital component pair tones are generated by said generating means with a duration shorter than a predetermined time duration and sent through the telephone line, a third control voltage in response to first digital component pair tones of the set of pair tones which first digital component pair tones are generated by said generating means with a duration longer than the predetermined time duration and sent through the telephone line, a fourth control voltage in response to second digital component pair tones of the set of pair tones which second digital component pair tones are generated by said generating means and sent through the telephone line, and a fifth control voltage in response to third component pair tones of the set of pair tones which third digital component pair tones are generated by said generating means and sent through the telephone line; g. means responsive to the second control voltage for converting said second means to a recording mode; h. means responsive to the third control voltage for recording a stop signal on the second cassette tape; e. means responsive to the fourth control voltage for converting said second means to a play-back mode; and j. means responsive to the fifth control voltage for converting said second means to a rewinding mode.

A remote control system for an automatic telephone answering and recording apparatus which includes first means for recording on and reproducing from a first cassette tape an answering statement, and second means for recording on and reproducing from a second cassette tape incoming messages by callers; said system comprising: a. answering means responsiVe to an incoming call arriving through a telephone line from a caller for automatically operating said first means to reproduce the answering statement previously recorded on said first cassette tape and for sending the statement through the telephone line toward the caller; b. incoming message recording means responsive to completion of the reproduction of the answering statement by said first means for operating said second means to record on the second cassette tape incoming messages sent by the caller through the telephone line; c. generating means for generating a plurality of kinds of pair tones comprising low tones and high tones; d. detecting means responsive to a set of pair tones selected from the kinds of pair tones which are generated in sequence by said generating means and sent through the telephone line for producing a first control voltage only when the set of pair tones coincide with a predetermined set of pair tones; e. first control means responsive to the first control voltage for driving said second means to rewind the second cassette tape; f. second control means responsive to stopping of the rewinding of the second cassette tape for driving said second means to reproduce the incoming messages; after said detecting means produced the first control voltage, said detecting means producing a second control voltage in response to first digital component pair tones of the set of pair tones which first digital component pair tones are generated by said generating means with a duration shorter than a predetermined time duration and sent through the telephone line, a third control voltage in response to first digital component pair tones of the set of pair tones which first digital component pair tones are generated by said generating means with a duration longer than the predetermined time duration and sent through the telephone line, a fourth control voltage in response to second digital component pair tones of the set of pair tones which second digital component pair tones are generated by said generating means and sent through the telephone line, and a fifth control voltage in response to third component pair tones of the set of pair tones which third digital component pair tones are generated by said generating means and sent through the telephone line; g. means responsive to the second control voltage for converting said second means to a recording mode; h. means responsive to the third control voltage for recording a stop signal on the second cassette tape; e. means responsive to the fourth control voltage for converting said second means to a play-back mode; and j. means responsive to the fifth control voltage for converting said second means to a rewinding mode.
Claim 3
Dependent Claim
35 words
A remote control system as defined in claim 1 in which said generating means comprises a touch-tone telephone operated by push-button pushing manipulation to generate said pair tones corresponding to numerals from 0 to 9.
Claim 4
Dependent Claim
49 words
A remote control system as defined in claim 1 in which said generating means comprises a portable generator for generating pair tones equivalent to pair tones generated by a touch-tone telephone operated by push-button pushing manipulation to generate pair tones of tones corresponding to numerals from 0 to 9.
