Abstract
Abstract A magnetic reproducing apparatus for reproducing recorded contents of a magnetic tape with the use of a reproducing head comprises a magnetic tape, a magnetic reproducing head, a tape drive mechanism, means for detecting an interlude or a cease period of a reproduced sound from a non-recorded portion of the tape, and means for compulsively maintaining the detected interlude period for a predetermined time.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
In a magnetic reproducing apparatus having a magnetic tape, a magnetic reproducing head, and a tape drive mechanism and for reproducing the recorded contents of the magnetic tape by the head, the improvement comprising means for detecting a duration of a reproduced sound from a recorded portion of the tape, means for detecting an interlude or a cease period of a reproduced sound from a non-recorded portion of the tape, and means for controlling a time base of the detected interlude period in proportion to a time base of the detected duration of the reproduced sound, the non-recorded portion of tape being controlled in proportion to the time base of reproduced sound duration so that when an interlude or cease period of reproduced sound exceeds a predetermined value, the time base of the interlude period is shortened by rapid forward running of the tape.
Claim 2
Dependent Claim
144 words
In a magnetic reproducing apparatus having a magnetic tape, a magnetic reproducing head, and a tape drive mechanism and for reproducing the recorded contents of the magnetic tape by the head, the improvement comprising means for detecting a duration of a reproduced sound from a recorded portion of the tape, means for detecting an interlude or a cease period of a reproduced sound from a non-recorded portion of the tape, and means for controlling a time base of the detected interlude period in proportion to a time base of the detected duration of the reproduced sound, the non-recorded portion of tape being controlled in proportion to the time base of reproduced sound duration so that when an interlude or cease period of reproduced sound exceeds a predetermined value, the time base of the interlude period is shortened by rapid forward running of the tape.
Claim 3
Dependent Claim
133 words
In a magnetic reproducing apparatus having a magnetic tape, a magnetic reproducing head, and a tape drive mechanism and for reproducing the recorded contents of the magnetic tape by the head, the improvement comprising means for detecting a duration of a reproduced sound from a recorded portion of the tape, means for detecting an interlude or a cease period of a reproduced sound from a non-recorded portion of the tape, and means for controlling a time base of the detected interlude period in proportion to a time base of the detected duration of the reproduced sound, and wherein use is made of two magnetic reproducing heads which are arranged at predetermined space and when these reproducing heads detect one and the same interlude period, simultaneously, the magnetic tape is subjected to rapid running.
Claim 4
Dependent Claim
133 words
