Abstract: 본 발명은 레인 위에서 게임자가 조종장치를 사용하여 실제 자동차 경주와 같은 분위기를 만끽하면서 자동차 경주 게임을 할 수 있도록 한 카레이싱 게임 시스템에 관한 것이다. 
     즉, 본 발명은 전원공급에 의하여 주행가능한 자동차(2)와, 상기 자동차(2)가 주행할 수 있는 소정길이 및 형태를 갖춘 레인(3), 상기 레인(3)상에서 행해지는 경기상황을 디스플레이 및 제어할 수 있는 디스플레이 및 제어수단(4), 상기 자동차(2)를 게임자가 조작할 수 있는 조종장치(5)로 대분하여 구성되는 것으로서, 자동차(2)의 저부에는 레인(3)상의 안내홈(6)에 안내되고 소정 각도 조절가능한 유도수단(8)이 부착하며,    레인(3)의   안내홈(6)에는   DC전원   공급을   위한 도전성테이프(7)가 부착되고, 레인(3)의 중도에는 속도측정을 위한 센서(9), 1등 감지를 위한 센서(10), 게임 종료된 자동차를 스타트라인(S) 상으로 정렬하기 위한 감지용 센서(9a)가 각각 설치되며, 레인(3)으로 공급되는 DC전원을 조정하는 조정장치(5)는 볼륨(11)을 조절하는 방아쇠(5a)와 1등으로 주행시 점등되는 램프(5b)를 가지며, 상기 볼륨(11)은 기판(13)상에 설치된 AD변환기(16)와 버퍼(15)를 통하여 전자변속기(12)에 의해 레인(3)상으로 공급되는 DC전원을 공급제어토록 하며, 디스플레이 및 제어수단(4)은 중앙콘트롤장치(4a)와 전광판(4b)으로 구성된 것으로서, 본 발명에 의하면 자동차(2)의 주행을 실제 운전자가 운전을 행하는 것과 동일한 정도로 미세조절에 의한 조정운전이 가능하여 자동차 경주게임을 사실감 있고 박진감 넘치게 진행할 수 있으며, 게임의 흥을 배가함은 물론 경기진행률을 높이고 시스템을 내구성있고 고장률을 줄여 수명을 일층 배가할 수 있는 등의 효과를 득할 수 있는 것이다.
