PROBLEM TO BE SOLVED: To prevent the outer peripheral surface of a surplus ball guide passage for guiding game balls flowing over from the upper tank of a bank of game machines from being pressurized by bank members such as the rear surface side member of a game machine and a paper money conveyor. SOLUTION: The bank of game machines is constituted as follows. The upper tank 27 for storing the game balls is arranged in the upper parts of a plurality of game machines 2 which are aligned with the rear surfaces facing. The game balls of the upper tank 27 are supplied to the game machines 2 via a ball replenishing passage 28. The game balls discharged from the game machines 2 are collected via a ball collecting passage 29 and also lifted-up to the upper tank 27 by a lift 30, thereby to guide the game balls flowing over from the upper tank 27 to the ball collecting passage 29 via the surplus ball guide passage 31. The surplus ball guide passage 31 includes surplus ball pipes 42 vertically arranged from the upper position to lower position of the game machines 2 between the rear surface side members 20 of the game machines 2 and the bank members 22. The surplus ball pipes 42 include thin diameter parts 43 each having an outer diameter not to interfere the rear surface side member 20 and the bank member 22. COPYRIGHT: (C)2010,JPO&INPIT
