<p>PURPOSE:To provide the tension device for a tape deck which prevents the disturbance in images, the interruption of sounds, etc., at the time of changing over a reproduction (play) state to a review reproduction state. CONSTITUTION:A back tension belt 104 is loosened by releasing curving of a back tension belt 104 at the time of changing over the reproduction state to the review production state, by which the pressurized contact of the back tension belt 104 with a reel base 105 is released. The tension lever 100 turns in an arrow C direction at this time and, therefore the lever does not turn in a direction where the tape 101 loosens and consequently, only the back tension is released without changing the pressurized contact pressure of the tape 101 with a rotary cylinder head 8.</p> |
