发明名称 PACHINKO MACHINE
摘要 PROBLEM TO BE SOLVED: To provide a pachinko machine in which a game condition of a big prize can be sufficiently enjoyed at the time of a big prize mode. SOLUTION: As a winning ball gets into a continuous winning hole 29, an opened condition for the next time is secured, and a restricting means is actuated to restrict a winning ratio of a hit ball into fluctuation members 27a, 27b by contracting opening sizes of the fluctuation members 27a, 27b, so time is required till a specified number of hit balls get into the fluctuation members 27a, 27b after they are restricted, thereby the opened condition for one time can be completed in a closer time to a specified time to enable a big prize mode to be sufficiently enjoyed in total.
