ABSTRACT:
A pneumatic sheet feeder includes a movable bottom plate which is disposed to form a constant angle with the uppermost sheet in a stack placed on a sheet receptacle, irrespective of the height of the stack. Sheets on the receptacle are attracted one by one by a negative pressure to be sequentially fed by a feed roller which is driven for rotation in an automatic manner.
