<p>PURPOSE:To prevent the occurrence of JAM and overlapping feeding without lowering the paper feeding speed in the continuous high-speed paper feeding of sheets. CONSTITUTION:When a conveyer belt 14 is rotated and driven as well as air is sucked from a sheet sucking parts 4, 8, the uppermost sheet S1 tacked on a sheet stacking tray 1 is sucked by a conveyer belt 14 and then conveyed. On the other hand, a sheet detecting means 46 outputs a signal when the sheet S1 is conveyed to the specific position, and the operation of a solenoid 43 is stopped by the signal. Thereby arms 32... held by a solenoid 43 in their housing position are rotated counterclockwise by a spring, and rollers 36,... attached to the lower end of the arms 32,... are protruded downward from the conveyer belt 14. A second sheet S2 is not sucked to the conveying belt 14 because of interference by the rollers 36,....</p> |
