Abstract
Abstract The present case is directed to a feature for dictation equipment that enables a dictator to indicate instructions directly on a recording medium for later use by a typist and that effectively eliminates separate index slips ordinarily required heretofore. The feature is adaptable for indicating ends of letters, and the like, as well as instructions for the transcriber. In a preferred embodiment, facilities are provided for the dictator to dictate instruction material simultaneously with a super-imposed tone signal that can be recognized later as signifying a special instruction. The feature is illustrated in conjunction with a disc-type recording and transcribing apparatus, but is adaptable for use with other kinds of media, such as belts, cards, etc.

Claim 1
Independent Claim
335 words
Dictation apparatus having an indexing arrangement for recording on a record medium audio signals including special audio signals representative of dictated material said record medium accommodating audio signals recorded thereon in a spiral path comprising a plurality of concentric portions and wherein said audio signals and said special audio signals comprise audio segments that occupy less than one of said concentric portions as well as audio segments that occupy one or more of said concentric portions on said record medium, comprising: a transducer for recording audio signals; drive means for relatively driving said record medium and said transducer in proximity with respect to one another in order for said transducer to trace said spiral path on said record medium; a source of audio signals representative of dictated material; interconnecting means operable to interconnect said source of signals with said transducer; mode control means for establishing a record mode of operation to operate said drive means and said interconnecting means in order to record said audio signals on said record medium by means of said transducer; superimposed signal means operable concurrently with recording of a said special audio signal segment for recording a signal of predetermined constant frequency in superimposed relation with respect to all of said segment; first control means operable when a special audio segment occupies at least one of said concentric portions to continue operation of said drive means and said superimposed signal means in order to record said superimposed signal only coextensively with said special audio segment; and second control means interconnected with said drive means and said superimposed signal means and operable when a special audio segment occupies less than one of said concentric portions on said record medium and following termination of said special audio segment to continue operation of said drive means and said superimposed signal means in order to thereby record said superimposed signal continuously for at least one of said concentric portions even though said audio segment occupies less than one concentric portion of said signal path.

Dictation apparatus having an indexing arrangement for recording on a record medium audio signals including special audio signals representative of dictated material said record medium accommodating audio signals recorded thereon in a spiral path comprising a plurality of concentric portions and wherein said audio signals and said special audio signals comprise audio segments that occupy less than one of said concentric portions as well as audio segments that occupy one or more of said concentric portions on said record medium, comprising: a transducer for recording audio signals; drive means for relatively driving said record medium and said transducer in proximity with respect to one another in order for said transducer to trace said spiral path on said record medium; a source of audio signals representative of dictated material; interconnecting means operable to interconnect said source of signals with said transducer; mode control means for establishing a record mode of operation to operate said drive means and said interconnecting means in order to record said audio signals on said record medium by means of said transducer; superimposed signal means operable concurrently with recording of a said special audio signal segment for recording a signal of predetermined constant frequency in superimposed relation with respect to all of said segment; first control means operable when a special audio segment occupies at least one of said concentric portions to continue operation of said drive means and said superimposed signal means in order to record said superimposed signal only coextensively with said special audio segment; and second control means interconnected with said drive means and said superimposed signal means and operable when a special audio segment occupies less than one of said concentric portions on said record medium and following termination of said special audio segment to continue operation of said drive means and said superimposed signal means in order to thereby record said superimposed signal continuously for at least one of said concentric portions even though said audio segment occupies less than one concentric portion of said signal path.
Claim 3
Dependent Claim
75 words
The apparatus of claim 1, wherein: said first control means comprises a microphone interconnected with said dictation apparatus for controlling operations of said apparatus and selectively operable means on said microphone enabling dictator control of said superimposed signal means; and wherein said second control means comprises a timer circuit having a time-out cycle equal to the time required to traverse at least one of said concentric portions for continuing operation of said superimposed signal means.
