  • Patent number: 5127869
    Abstract: A toy includes a board having a path and a plurality of animal figures drawn on the board along the path, and a toy sightseeing bus moved along the path. Electrically conductive members are formed on the path at positions opposing the animal figures for producing commands which specify the corresponding animals. A group of contacts are arrayed on the bottom of the toy bus in such a manner that the contacts come into sliding contact with the electrically conductive members. When the toy bus arrives at a position opposing an animal figure, a set of the contacts is closed selectively by the electrically conductive member corresponding to this animal figure so that the closed contacts generate a signal designating the animal.
