The supply of electricity feature null upper run aspect to the self-propelled body

摘要

PROBLEM TO BE SOLVED: To design a safety mechanism by which weak electric current leakage caused by short circuit between electrodes can be early and surely discovered in a two-storied racing game apparatus in which a model body running on the upper stage running face is guided through a magnetic force by means of an automatic traveling body running on the lower stage running face. ;SOLUTION: On the assumption of an electricity feeding mechanism based on an electricity feeding board and a number of electricity feeding terminals of the automatic traveling body 10, an automatic traveling body electric current detecting means 30 for detecting electric current consumption of each automatic traveling body 10 is provided on the automatic traveling body, and the detected electric current value is transmitted to a control device of a game machine main body. An electric current adding means for adding the electric current consumption value transmitted from the automatic traveling body electric current detecting means 30 is provided on the game machine main body and a means for detecting electric current of the electricity feeding board fed to the electricity feeding board is provided on the game machine main body and the electric current added value is compared with the electric current of the electricity feeding board and when the electric current of the electricity feeding board exceeds the electric current added value at least by a specified value, electric current exceeding time is measured and when the measured electric current exceeding time surpasses a specified time, feeding electricity to the electricity feeding board is stopped.;COPYRIGHT: (C)2003,JPO
