PROBLEM TO BE SOLVED: To ensure stable base value.SOLUTION: A game ball which has not entered a second start ball charging hole 15a may be induced to a normal ball charging hole 16a by an induction path YT to enter the normal ball charging hole 16a. In addition, induction members 17a, 17b as components of the induction path YT are a resin member comprising an induction surface (fourth side surface S4) so that the induction members 17a, 17b are hardly deformed. Together with this, ratio of entering of a game ball into the normal ball charging hole 16a positioned below the induction members 17a, 17b decreases, thus the ratio of entering of a game ball into the normal ball charging hole 16a is stabilized. Thereby, upon calculating a base value, even n a case where a game ball has not entered the second start ball charging hole 15a, a stabilized base value is ensured due to entering of a game ball into the normal ball charging part 16.SELECTED DRAWING: Figure 7 |
