<p>PURPOSE:To prevent the slip between a magnetic tape and an impedance roller by pressing the magnetic tape which is drawn out from a cassette by a magnetic tape drawing out mechanism to the impedance roller by a pressing roller. CONSTITUTION:When a pinch roller arm 18 is rotated toward a capstan 23 by a magnetic tape traveling mechanism, an impedance roller arm 22 is rotated linking therewith by a link mechanism 19 till it is press-fixed to the capstan 23 while interposing the magnetic tape 8, therefore, the link mechanism 19 is extended against the spring force of a spring 20. As the result, the spring force acts upon the impedance roller arm 22, and the magnetic tape 8 is pressed to the pressing roller 2 by the impedance roller 21 with the proper amount of pressing strength. Thus, the jitter in wide band is attenuated.</p> |
