Abstract
In a tape driving system having both a tape reel holder which puts thereon a tape reel and a tape drawing arm which leads a part of the tape from the tape reel to a given portion, there is installed a reel holder brake device. The device has a brake band having a major portion operatively put around the reel holder. A tension regulator arm is pivotal about a pivoted portion thereof between the loading and unloading positions. The tension regulator arm has the given portion. A spring biases the tension regulator arm to pivot toward the unloading position. A drive gear drives the tape drawing arm when rotated. The drive gear has in one surface thereof a cam groove. A first pivotal arm has one end pivotally connected to one end of the brake band and the other end equipped with a follower pin slidably engaged with the cam groove. A second pivotal arm has one end pivotally connected to the tension regulator arm and the other end pivotally connected to the other end of the brake band. With this arrangement, the reel holder brake device can apply the reel holder with two types (viz., smaller and larger) of brake torque.
