SOLUTION: A storage recessed part is formed in a position not overlapping longitudinally with a safe ball passage of a back mechanism board 10 of the pachinko machine 1, and a shooting control device 30 serving as a first control device without a built-in ROM disposed in the storage recessed part. A game control device 40 is disposed as a second control device with a built-in ROM in the state of overlapping a first control device on the rear side in the longitudinal direction of the pachinko machine.
