摘要： A reel stand includes (a) a reel base for engaging a reel and driving the reel, (b) a bearing disposed in the reel base and being extended through by a rotary shaft, and (c) a spring being urged to the rotary shaft. This construction allows the reel stand to integrate a brake torque mechanism into its downsized body, and to provide a tape with uniform tape tension when the tape is taken up or supplied. The spring is pressed to the shaft to produce brake torque, which lowers the peripheral velocity of the shaft. As a result, less frictional heat is produced, which reduces changes in friction factors due to the heat.

摘要翻译：卷轴架包括：（a）用于接合卷轴并驱动卷轴的卷轴底座，（b）设置在卷轴基座中并通过旋转轴延伸的轴承，（c）弹簧被推压到旋转轴。这种构造允许卷轴架将制动扭矩机构集成到其小型化体中，并且当带被吸收或供应时，提供具有均匀带张力的带。弹簧被按压到轴上以产生制动力矩，这降低了轴的圆周速度。结果，产生较少的摩擦热，这减少了由于热量引起的摩擦系数的变化。
