Model driving machine, drive unit and model

Abstract

A four-legged model racing machine 150 that drives, for example, models 20 of horses for racing can make the legs of the models swing up and kick up. The models 20 each having a body and plural legs supporting the body move on a partition board 5 serving as a racetrack board. Each model 20 is driven for motions by a mobile drive unit 160 disposed under the partition board 5. The plural legs of the model 20 can swing back and forth. Magnets Mfl, Mfr, Mrl and Mrr are embedded in the leg tips of the plural legs, respectively, with one of the magnetic poles of each of the magnets Mfl, Mfr, Mrl and Mrr facing the underside of the leg tip (facing down). The drive unit 160 is provided with adjacently arranged plural magnet pairs mfl, mfr, mrl and mrr respectively corresponding to the leg tips of the legs and capable of reciprocating parallel to a running direction along the lower surface of the partition board 5. The paired magnets are arranged longitudinally with their magnetic poles respectively of different polarities facing upward. A reciprocating mechanism 180 drives the magnet pairs mfl, mfr, mrl and mrr for longitudinal reciprocation to make the plural legs swing by making the magnetic forces of the magnet pairs mfl, mfr, mrl and mrr act on the magnets Mfl, Mfr, Mrl and Mrr attached to the leg tips of the plural legs of the model 20.
