ABSTRACT:
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.
