Abstract: In the tape winder for winding a tape on a reel to form a tape roll, a nozzle which blows a gas toward an outer peripheral surface of the tape roll at a winding time of the tape is fixed on a slider, which is slidably supported on a rail. In this way, the nozzle is supported movably forward and backward with respect to the tape roll. Moreover, the nozzle is pressed toward the tape roll by an air cylinder with a constant pressing force. Thus, the nozzle is allowed to accurately follow an outer peripheral surface of the tape roll, and a constant pressure can be applied to the outer peripheral surface of the tape roll. Consequently, the tape can be wound with an adequate winding tightness.

Abstract: The reel spring for use in a magnetic tape cassette comprises a fixing portion which is fixed to a boss of a cassette case by means of a boss hole, an arm portion which forces a reel in an axial direction of rotation and a bending portion provided between the fixing portion and the arm portion in an L-like shape. The ratio of a length of the fixing portion of the reel spring to a height of the boss is 4.0 or more. The length of the fixing portion is longer than that of the arm portion by 1 mm to 5 mm. The magnetic tape cassette employs the reel spring which is capable of enhancing production efficiency in fabricating the magnetic tape cassette while maintaining a specified force of the reel spring.

A gap is left between the end surface of the distalface of the projection and the bottom of the recess defining an internal space. At least one air hole is formed communicating with the internal space, and suction may be applied to the internal space through the air hole. Also, a dust-blocking rib may be provided on at least one of the recess and projection surrounding the abutting welding portions.
