Abstract
PURPOSE: To prevent the charge of magnetic tape, by constitution that the static electricity caused on the magnetic tape is grounded on the capstan shaft by coating conductive rubber on the external circumference of the pinch roller.
CONSTITUTION: The pinch roller 16 is formed with non-conductive rubber such as neoprene rubber mounted on the external circumference of the conductive shaft 30 such as arbor bolted on the conductive bearing 28. The conductive rubber 18 is coated on the external circumference of the pinch roller 16. The coating layer consisting of the conductive rubber 18 has sufficiently greater width than the width of the magnetic tape 14 and the upper and lower end not in contact with the magnetic tape is contacted with the capastan shaft 17. Thus, since the conductive rubber 18 is coated on the external circumference of the pinch roller 16, even if static electricity is caused on the magnetic tape 14, it is grounded to the capstan shaft 17 via the conductive rubber 18. Accordingly, the charge of magnetic tape can be prevented.
