PROBLEM TO BE SOLVED: To provide a ball discharging device to discharge pachinko balls by rotation of a lead screw in which only one ball sensor is set for two lines of ball moving passages to count pachinko balls passing both ball moving passages to reduce manufacture cost compared to devices with a plurality of ball detectors, and facilitate signal processing. SOLUTION: A lead screw 1 is vertically supported to be rotated by a pulse motor 2, ball moving gutters 5a, 5b in which pachinko balls (p) are dropped in accordance with rotation of the lead screw 1 are respectively vertically formed at symmetric positions on both sides of the lead screw, and a ball detector 12 to detect the pachinko balls (p) released from restraint by the lead screw 1 to be dropped from lower ends of both ball moving gutters 5a, 5b is set to count the pachinko balls (p).
