Abstract

밀착형 이미지 센서는 1개의 광원에 의해 양 측면에서 판독 라인으로 광을 조사하기 위해 판독 라인(9)의 위치에서 원고의 표면의 법선 방향으로 광을 선정된 경사각으로 방출하는 광원(3); 광원(3)에서 판독 라인(9)로 광을 유도하기 위해 원고를 지지하는 원고 지지 부재(6) 및;상기 원고 표면으로부터의 광을 수광하는 광전 변환 장치부(5)를 포함한다. 최소한 판독 라인에 따라 광원(3)의 배열 측면에 대향하는 측면 상에 배치된 상기 원고 지지부재(6)의 부분은 광원(3)으로부터 광의 일부를 반사시켜서 판독 라인(9)로 유도하기 위한 반사 표면을 갖고 있다.
