The operational winning a prize

摘要

PROBLEM TO BE SOLVED: To provide a pachinko game machine in which blades, arranged in a center role object unit to perform an opening/closing operation, can made appear bigger visually.;SOLUTION: Notched parts 11a and 11b are formed at the left and right sides of a nearly center part of a base board 19. The notches 11a and 11b are formed to eliminate the existence of the base board 19 at least inside an area where guide blades 52a and 52b are changed by an opening/closing operation. Thus, other members are not superimposed in the change area of the guide blades 52a and 52b to be opened/closed. Then the guide blades 52a and 52b seem to be opened/closed independently and separately from a variable prize-winning device 53 and also the blades 52a and 52b look bigger by sensation of sight. Thus, a player is allowed to have expectation for more prize-winning in the variable prize-winning device 53 through the use of game balls flowing- down through a game area.;COPYRIGHT: (C)2003,JPO
