PROBLEM TO BE SOLVED: To obtain a pachinko game machine wherein when game balls are automatically supplied according to the residues of balls, balls are not unnecessarily supplied due to blocking of balls near a ball flow part. SOLUTION: In an upper receiving dish set 28 of the pachinko game machine, a hole part 134 is formed in the bottom surface 132 of a dish part 130 for storing a large number of game balls to dispose a game ball quantity detecting part 140. The part 140 includes a detecting plate 146 fixed to a metal support 144, and the top side of the plate 146 is aligned with the bottom surface 132 so as to close the hot part 134. A strain gauge 148 connected to a bridge circuit is bonded to the circumferential wall of the support 144 to activate automatic feed functions for game balls based on the voltage outputted from the bridge circuit. Thus, even if game balls are blocked near the ball flow part, the balls can be prevented from being unnecessarily and automatically supplied since the residues of balls at the part 140 are kept unchanged.
