<p>PURPOSE:To prevent the generation of a load against the running of a magnetic tape and to attain the stable running of the tape by performing the interruption of rotation of a supply reel base by a brake means in the direction opposite to the supplying direction of the supply reel base. CONSTITUTION:In the forward reproducing state, when the turning force is applied to the winding part 3a at the supply side of the magnetic tape 3 in the direction of the arrow C, i.e., clockwise by the vibration from the outside such as the reciprocated turning operation, etc., the turning force is applied also to the 2nd reel base 21 in the same direction, but a brake rubber 15b of a 2nd break lever 15 is made in press-contact with a pulley part 21b by a 2nd spring 19 and further the biting force is exerted, therefore, the interrupting force is imparted to the turn based on the turning force of the 2nd reel base 21 to reduce the load for the tape running, then the running of the magnetic tape 3 is stabilized.</p> |
