ABSTRACT:
A sheet paper feed apparatus has a hollow center shaft, a roller which has peripheral holes and rotates around the center shaft, and a negative pressure source communicating with the center shaft. Rotation of the roller causes the peripheral holes to successively create a suction action to adhere and feed the sheet paper. The center shaft has an opening at a position shifted by a predetermined angle in the direction of sheet feed with respect to a surface that is vertical with respect to the sheet paper feed surface and passes through a center of the center shaft.
