Abstract

PURPOSE: To make a tape run stably and prevent a wow and flutter phenomenon, by detecting the rotary speed of the pulley which rotates contacting with a tape, and controlling a rotation of the reel base driving motor of the tape take-up side.
CONSTITUTION: The pulley 9 which contacts through the tape 8 to the pad 7f from the window hole 7e of the cassette half 7 is rotated by friction. And when running of the tape 8 has become quick or slow, the rotary speed of the pulley 9 is detected by use of the photoelectric detection means, etc. consisting of a projector 10 and a photoreceptor 11, and a rotation of the driving motor of the reel base 5 (6) which becomes the take-up side is controlled by use of a signal which has been converted to an electric signal from the aforesaid detection signal, by which the tape 8 is made to run at constant speed. Thus, it is possible to make a tape run stably and prevent generation of a wow and flutter phenomenon.
