PURPOSE:To prevent a paper from being superposed and fed(double feeding), the paper from being unsupplied and the paper from being jammed even in the case that the paper where static electricity is easily generated such as a 2nd original drawing paper is fed by a both-side device provided with a paper tray which is used for both sides as well as one side. CONSTITUTION:An air blower 5 which sends air to the paper P placed on a paper tray 30 to make it float is provided in the paper supply part of the both- side device 10. By making the air get between the papers placed on the tray 30 at the time of feeding the paper, rubbing of the papers against each other is eliminated and the static electricity being the cause of jamming is prevented from being generated. Furthermore, it is more effective to add ion having property for removing the static electricity to the air. |
