stop member 14 an ultrasonic vibrator 24 disposed at a predetermined position of the rotation stop member 14 is held by the stopper plate 28 further one end face of the ultrasonic vibrator 24 is bonded to the surface of the guide member 21 for example for thereby preventing the guide member 21 from rotating a terminal plate 25 is secured to the rotation stop member 14 by fitting a screw 26 into a tapped hole 14b of the rotation stop member 14 a rotation stop pin 29 is used in connection with a base 32 see fig5 so as to prevent the tape guide device 17 from rotating in the present invention a material of the guide member 21 is not limited to the above mentioned ceramic material and the guide member 21 might be formed of a conductive ceramic material mainly made of alumina added with titanium oxide thus the occurrence of static electricity can be avoided for thereby allowing the tape to run stably when the guide member 21 is made of a conductive material it is needless to say that a ground material for grounding the guide member 21 must be provided further the supporting protrusion 19b might be made of a soft material such as rubber plastics or the like if the supporting.
