Abstract:
1. A static eliminator for an insulating sheet, in which at least two static eliminating units are provided in the traveling path of an insulating sheet with an interval kept between them in the traveling direction of the sheet; each of the respective static eliminating units has a first electrode unit and a second electrode unit disposed to face each other through the sheet; the first electrode unit has a first ion-generating electrode and a first shield electrode having an opening near the pointed ends of the first ion-generating electrode; and the second electrode unit has a second ion-generating electrode and a second shield electrode having an opening near the pointed ends of the second ion-generating electrode, wherein at each of the respective static eliminating units, (a) the voltage applied to the first ion-generating electrode and the voltage applied to the second ion-generating electrode are substantially opposite to each other in polarity, and (b) at each position in the width direction of the sheet, if the interval between the pointed end of the first ion-generating electrode and the pointed end of the second ion-generating electrode in the traveling direction of the sheet is d is satisfied.
