Abstract

PURPOSE: To prevent low-quality sound recording and reproducing, by applying muting to the sound circuit for speed change.
CONSTITUTION: When the running speed of tape 1 which is a recording medium is not regular, the sound circuit to record or reproduce sound is subjected to muting, and muting is applied to sound reproducing circuit 3 to stop sound output to output terminal 4 for speed change instruction. Even if speed change is released, running of tape 1 is not returned to the original speed instantaneously but is returned to the original speed after the time delay determined by muting release delay circuit 9, and after that, muting is released to output the sound output.
