Abstract
A tape guide device has a guide member, a support shaft, flanges, a main shaft, a coil spring, a height adjustment nut, and a vibrating device, wherein the support shaft is disposed inside the guide member, the support shaft has teeth facing to a position of a node when the guide member is vibrated by the vibrating device, the teeth and the guide member are fixedly bonded to each other by an adhesive that presents a feature of a resilient member after the adhesive was cured, the main shaft is engaged with the support shaft so as to become freely slidable, the flange is attached to the support shaft with a clearance kept between it and an end face of the guide member and the guide member and the flanges can be adjusted in height under or against the bias of the coil spring by turning the height adjustment nut. The support shaft and the guide member are fixedly bonded to each other by the adhesive that becomes a resilient member after having been cured. Therefore, the ultrasonic vibration tape guide device that can prevent the vibration of the guide member from being attenuated due to the contact with the flanges and that can make the guide member inexpensive has a function to adjust the guide member and the flanges in height with high accuracy.
