Abstract

슬래트 모터의 회전속도를 감지하는 홀센서를 채용하여 이 슬래드 모터에 의하여 회동되는 광픽업의 위치를 검출하는 씨디-롬 드라이브의 광픽업 위치 검출 장치에 관하여 개시한다. 이 광픽업 검출 장치는 소정의 기어열을 통하여 광픽업을 구동시키는 슬래드 모터와, 슬래드 모터의 회전에 따라 회동하는 회전부재와, 회전부재의 소정부위에 부착된 마그네트와, 마그네트와 상호 작용하여 회전부재의 회전속도를 감지하도록 마그네트와 대응하여 메인회로기판의 소정부위에 설치된 홀센서와, 홀센서로부터 받은 신호를 처리하는 마이크로 프로세서를 구비한다, 이와 같은 씨디-롬 드라이브의 광픽업 위치 검출 장치는 기능 수행에 필요한 부품 수가 절약되어 작업공수가 감소하고 제품단가를 낮추어 경쟁력 있는 제품을 생산할 수 있다는 이점이 있다.ROM drive for detecting the position of an optical pickup rotated by the sled motor by employing a Hall sensor for detecting the rotational speed of the slat motor. The optical pick-up detecting apparatus includes a sled motor for driving the optical pickup through a predetermined gear train, a rotating member rotating in accordance with rotation of the sled motor, a magnet attached to a predetermined portion of the rotating member, And a microprocessor for processing a signal received from the Hall sensor. The optical pickup position detection of the CD-ROM drive is performed by a Hall sensor mounted on a predetermined portion of the main circuit board in correspondence with the magnet, The device has the advantage of reducing the number of parts required to perform the function, reducing the work flow and lowering the product cost to produce a competitive product.
