ABSTRACT:
A tape run speed-changing circuit which comprises a motor driven at a speed conforming to any tape run speed for the recording or playback mode and also at a speed matching any tape run speed for the cue or review mode, a first tape run speed-changing device for specifying any tape run speed for the cue or review mode, and a second tape run speed-changing device which selects any tape run speed for the recording or playback mode and whose operation mode is changed over interlockingly with that of the first tape run speed-changing device. When the second tape run speed-changing means device specifies a first tape run speed for the recording or playback mode, then the first tape run speed-changing means device selects a first tape run speed for the cue or review mode; and when the second tape run speed-changing device specifies a second tape run speed for the recording or playback mode, then the first tape run speed-changing device selects a second tape run speed for the cue or review mode.
