<p>PURPOSE:To remarkably suppress the generation of abnormal sound generated at the time of generating a standing wave to a guiding member without improving the dimension precision of the parts of a supporting shaft, etc., and simultaneously to make the cost of a tape guiding device low by supporting the guiding member with a soft supporting ring whose tip has a curved surface shape inserted to a recessed part formed on the supporting shaft. CONSTITUTION:This device is provided with the pipe-like guiding member 2 to guide a tape, an ultrasonic exciter 3 whose one end is a free end and the other end is fixed to the guiding member 2 and to vibrate the guiding member 2 with a standing wave and a supporting shaft 7 to support the guiding member 2. The supporting ring 8 is provided on the circumference surface of the supporting shaft 7 and the guiding member 2 is supported with this supporting ring 8 and simultaneously at least the supporting ring 8 is constituted of soft material.</p> |
