<P>PROBLEM TO BE SOLVED: To provide an electrostatic attraction system paper carrying device preventing ozone generation problems and assuring attraction effect. <P>SOLUTION: An electrostatic attraction belt 5 is applied around a conductive roll 2 of a grounded paper feeding side and a conductive roll 3 of a paper delivery side. An electrifying roll 10 connected to a direct current high voltage power supply 15 is brought into pressure connect with the conductive roll 2 of the paper feeding side through the electrostatic attraction belt 5. An antistatic brush 16 is deployed before an electrifying brush with respect to the rotational direction of the electrostatic attraction belt and near the electrostatic attraction belt abutting the conductive roll 2 of the paper feeding side. A paper sheet 7 after passing over the electrifying roll is carried with being electrostatically attracted by the belt. This eliminates the use of a corona static eliminator, suppressing ozone generation problems, and reducing manufacturing costs. Irregular electrification generated on the belt after the paper sheet is stripped can be surely eliminated, allowing assured attraction effect to improve carrying reliability. Changing the voltage applied to the electrifying roll according to the paper type and environmental conditions can adjust the attraction force to an optimum level. <P>COPYRIGHT: (C)2004,JPO |
