SUMMARY OF THE INVENTION In this case, it is necessary to provide a projection device that is used to prevent the fan from being damaged when the antistatic test is performed. φ A projection device includes a wind dragon in an outer private casing. One of the outer conductive members disposed on the outer surface and the at least one fan is disposed. The wind: two years of her life. The conductive sheet covers the surface of the shaft and is electrically connected to the ground. Compared with the prior art, the position of the projection is set to be disposed by the conductive sheet by the conductive sheet when the projection is placed in the antistatic test. To the ground of the projection device, 201007333 Avoid static damage to the fan during antistatic testing.
