Abstract

광주사모듈은 메탈베이스,메탈베이스의 한끝을 가로질러 장착된 제1회로보드 및 제1회로보드에 수직으로 장착된 제2회로보드를 가진다. 메탈베이스는 주사빔을 형성하기 위한 광방출기를 지지하고 방출기에 대하여 탈열제의 역할을한다. 메탈베이스에 부착된 유연성 지지부는 진동운동을 하는 거울을 지지한다. 모듈은 거울의 상반된 운동을 일으키기 위하여 전형적으로 영구자석 및 전자석의 형태로 작동메카니즘을 포함한다. 모듈에 포함된 검출기는 빔에 의하여 주사되는 표시로부터 반사되는 광을 감지한다. 유연성 전자케이블은 제 1회로보드 및 제2회로보드의 회로를 연결함으로써 회로가 함께 작동하여 주사기모듈의 작동에 필요한 모든 신호를 형성하고 검출기로부터의 전자신호를 처리하도록 한다. 바람직한 실시예는 거울 및 자석중 하나 사이에 위치한 평면스프링으로 구성되는 유연성 지지부를 포함한다.모듈의 구성요소는 자석무게와거울무게가 균형을 이루도록 디멘젼된다. 본 발명은 또한 두가지 다른 진동수에서 두개의 직교하는 방향으로 동시에 빔을 주사하는 시스템도 포함한다. 이러한 양방향 주사는 2차원의 바코드를 판독하기 위한 라스터주사패턴을 형성할수 있고, 또는 이러한 주사는 절단된 바코드를 판독하기 위한 운동하는 지그재그 패턴을 형성할 수 있다.
