PROBLEM TO BE SOLVED: To properly prevent a band-like body from vibrating without partially changing the temperature of the band-like body, when a vibration prevention device prevents the band-like body from vibrating, in the middle of transportation of the band-like body.SOLUTION: A vibration prevention device 10 for preventing vibration of a band-like body 1 includes: a vibration detection device 11 for detecting vibration of the band-like body 1 to be transported; a sonic wave output device 14 for radiating toward the band-like body 1 sonic waves for suppressing vibration of the band-like body 1 detected by the vibration detection device 11; and a control device 12 for controlling the sonic waves radiated from the sonic wave output device 14 toward the band-like body 1, on the basis of vibration information of the band-like body 1 detected by the vibration detection device 11.SELECTED DRAWING: Figure 1 |
