[Abstract] Many roads intelligence competition quiz machine is composed with main electric circuit and expanding electric circuit. The answer circuit, the timing circuit, the warning circuit and the cycle time control forms the main electric circuit. The preference coding circuit, the lock memory and the coding circuit shows the signal on the screen. The control circuit and the compere switch can startup the warning circuit. Those two points are how to the main circuit working. The timing circuit and the coding circuit take the second pulse signal displaying on the screen in order to timing, this is expanding circuit.
