発生を防止できる。(Function) Since the tape running guide using semiconductor porcelain of the present invention is made of porcelain, there is little wear caused by tape running. Also, since it is semiconductor porcelain, it is less likely to be magnetized than metal. In addition, semiconductor porcelain has a suitable electrical conductivity and has the property of discharging electric charge without accumulating it, so that it is possible to ground the electric charge caused by running the tape, thereby preventing the generation of noise.
