Abstract:
1. A racing game machine, comprising: a lower traveling field; a plurality of guide lines provided on the lower traveling field; a plurality of self-propelled members, each including: an upper traveling field, extending above the lower traveling field; a plurality of miniature members, each associated with one self-propelled member, the miniature members placed on the upper traveling field so as to travel thereon in accordance with the traveling of the self-propelled members through magnetic force; a central controller, which collectively monitors the displacement signal of each self-propelled member to recognize relative position relationship among the self-propelled members, and which issues at least a speed changing instruction and a path-switching instruction for each self-propelled member, based on the relative position relationship, wherein the travel controller of each self-propelled member changes a traveling speed thereof when the speed changing instruction is received from the central controller; and wherein the travel controller of each self-propelled member switches a traveling path thereof from the traced guide line to another guide line, when the path-switching instruction is received from the central controller.
