PROBLEM TO BE SOLVED: To realize a pachinko game machine which enables the winning of the prize at a higher probability with the game balls taken into a center case. SOLUTION: A distribution chamber 2 is formed deep in a ball outlet 8. Two vital nails 7a are driven into the rear wall 6 of the chamber being disposed parallel horizontally. The vital nails 7a stick ahead of the ball entry slot 8 passing through the distribution chamber 2. The game balls flowing between the vital nails 7a in the distribution chamber 2 drop as intact and are detected with a detection switch 40 via a downflow path 11. The game balls left without flowing between the vital nails 7a roll on a non-guide part 3a to be discharged to a playing area 20a from the ball outlet 8. COPYRIGHT: (C)2006,JPO&NCIPI
