Abstract
A rotary type sheet counter disc gradually counts corner portions of stacked-up sheets from the top sheet to the bottom sheet. The sheet counter disc includes an upper disc and a lower disc on which the upper disc is placed, the lower disc having a plurality of sheet suction fins equally spacedly arranged on a peripheral edge portion thereof. The sheet suction fins each have a sheet suction port which is open at a lower surface thereof, and the lower disc has a plurality of sheet loosening claws projecting in a rotating direction of the sheet counter disc from leading ends of the sheet suction fins. A plurality of sheet introduction slits are formed between upper surfaces of the sheet loosening claws and a lower surface of a portion of the upper disc which covers the sheet loosening claws. The sheet introduction slits each have a sheet introduction port opening at a distal end portion of each sheet loosening claw, and the upper disc has a plurality of sheet outlet slits equally spacedly arranged on a peripheral edge portion thereof. The sheet outlet slits each have a sheet outlet port communicating with each sheet introduction slit and opening at an upper surface of the upper disc,…
