To provide a Pachinko ball counter which improves speed and reliability of ball counting by installing a system to disperse Pachinko balls almost uniformly, balls which are flown into each ball counting lane from a ball- receiver.

A system is installed in a tray part 12 placed under a hopper part 11 of the ball receiver 8 to disperse Pachinko balls thrown into the ball receiver 8 almost uniformly to flow into each ball counting lane 13a of a counting part 13. This dispersing system is a dispersing part component 15 forming a guiding flat of a guiding space 14, which guides thrown in Pachinko balls to a back and forth direction of a ball counting device with a prescribed angle set to the horizontal face to flow into each ball counting lane 13a of the counting part 13. This guiding flat is composed of the dispersing part component 15 which is forming left and right gradients slanted having the same inclination angle and being directed to left and right tips of the guiding space 14 from the center axis of the same, and a guiding groove 16 made by an under tip of the dispersing part component 15 in the guiding space 14.
