摘要： A line-illuminating device comprises a white casing, a bar-shaped light guide housed within the casing, and light-emitting units provided on opposite ends of the bar-shaped light guide. The light-emitting unit has a substrate forming a circuit on which a lead wire for power supply is installed. Formed on a surface of the substrate facing the bar-shaped light guide is a window for coupling in which a green-color light-emitting diode and a blue-color light-emitting diode are installed. Likewise, the light-emitting unit has a substrate on which a lead wire for power supply is installed. Formed on a surface of the substrate facing the bar-shaped light guide is a window for coupling in which two red-color light-emitting diodes are installed.

摘要： 용장구역이 짧은 조명장치와 이것을 삽입한 화상 독취장치를 제공한다.
발광 유닛(10)의 발광소자 중 가장 봉형상 도광체(3)의 바닥면(3b)로부터 먼 위치에 있는 청색 소자(10a)로부터 방사된 빛 중, 종래와 동일하게 직접 도광체(3)의 단면으로부터 도광체 내에 입사된 빛은, 도 4(a)에 나타내는 바와 같이 용장구역이 길어진다. 그러나, 청색 소자(10a)로부터 방사된 빛 중, 상기 간극(13)을 통과한 빛은, 도 4(b)에 나타내는 바와 같이, 차폐부(14)의 이면에서 반사되어 절결(12)의 표면으로부터 도광체(3) 내에 입사된다. 이 차폐부(14)로부터의 반사광은 수직에 가까워지기 때문에 용장구역이 매우 짧아진다.

摘要： [PROBLEMS] A light guide and a line illuminator incorporating it in which the deterioration of a read out image can be suppressed even when the document surface is floating by spreading the intensity distribution of light in the longitudinal direction at a position (document position) of an article being illuminated. [MEANS FOR SOLVING PROBLEMS] In a light guide (10) arranged such that a light entering from the end face exits from an exit face provided along the longitudinal direction while reflecting off the inner surface, a side face shape orthogonal to the longitudinal direction has a curved surface (1) of first elliptic arc, a curved surface (2) of second elliptic arc, a first exit face (3), a second exit face (4), and a light scattering part (5) formed at an elliptic focal position (or in the vicinity thereof) on the major axis plane of each ellipse. Condensing position of a light reflected off the first curved surface is different from the condensing position of a light reflected off the second curved surface.

摘要： [PROBLEMS] A document surface is illuminated efficiently by utilizing the characteristics of a compound paraboloid condenser (CPC) reversely to convert scattering light from some limited area over the entire angle into radiation light limited to a specified exit angle thereby minimizing spread of light. [MEANS FOR SOLVING PROBLEMS] In a light guide (10) arranged such that a light entering from the end face exits from an exit face (4) provided along the longitudinal direction while reflecting off the inner surface, a cross- sectional shape orthogonal to the longitudinal direction has two parabolas (2, 3) facing each other, a segment (bottom face) (1) connecting the focal points (a, b) of two parabolas (2, 3), and a segment corresponding to the exit face (4). A scattering pattern of white ink is formed on the segment (bottom face) (1) connecting the focal points (a, b).
