<p><P>PROBLEM TO BE SOLVED: To provide a game ball guider in a game machine that can changeably mount a game device such as a winning opening to be mounted on a game board with accuracy and ease, and unerringly exhibits an expected specified performance and is easy to use. <P>SOLUTION: A game ball released from release openings 53 and 53 of guiding routes 52 and 52, reduces the rolling speed while systematically reciprocating to and fro on a first stage 60 by a guiding member 50. The game ball moving to a third stage 80 from the circular space of a first slope 64 formed of a notch 61 and the guide groove 55 of a back wall 56 falls to a start winning opening 11 through a central concave portion 81. The start winning opening 11 is easily and changeably mounted to the game board 21, precisely with respect to the central concave portion 81, regulated by a fitting protrusion 77 and a fitting recess 36. The game ball falling on the game board 21 from the central concave portion 81 enters the start winning opening 11 with high probability. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
