Description

컬러화상독해장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본원 발명의 일실시예를 나타내는 컬러화상독해장치의 요부단면도.
제2도는 각 광원의 구동파형도.
제3도는 신호처리회로의 구성도.

Claims (1)

  1. 원고면의 독해개소를 조사하는 다색광원으로서, 지향성 광원과 무지향성 광원을 혼재하여 배설하고, 이들광원을 전환제어에 의해 차례로 점등시키는 동시에 이들 광원에 의해 조사된 상기 독해개소로 부터의 반사광을 수광소자로 수광해서 컬러화상을 얻도록 한 컬러화상독해장치에 있어서, 상기 무지향성 광원과 상기 원고와의 사이에 상기 무지향성 광원으로부터 방사된 조사광에 지향성을 갖게하는 광학수단을 설치한 것을 특징으로 하는 컬러화상독해장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
