不具合があった。Prior Art The line light device of conventional color copying machines uses a white light tungsten lamp or fluorescent lamp as a light source, and the white light from this light source is separated into blue, green, and red by three color separation filters. Then, the image 1afr light is carried out. However, in this method, all light other than the necessary light is absorbed or reflected by the color separation filter and becomes a loss, so there is a problem that the power consumption of the light beam is large.

1tにくいなどの不具合があった。In order to improve this problem, two fluorescent lamps were used: a 1" light lamp that mixed W phosphor and green phosphor, and a fluorescent lamp that mixed 1T phosphor and red phosphor. Exposure equipment L is also advocated, which uses a light source and separates the light from these light sources with a color separation filter to perform image exposure, but since a single fluorescent lamp is used during exposure, the amount of light is insufficient. There were problems such as difficulty in obtaining the desired exposure.

In the figure, 1 is the main body of the close-up copying machine, and the document A to be copied is shown at the top.
A platen 2 is provided on which the document is placed, and two light sources 3.4 are installed below the platen 2 to illuminate the copy surface of the document. Part 3 of each of the light sources 3.4 above is a fluorescent lamp that is a mixture of blue and green fluorescent materials, and has the characteristics shown in curve A in Fig. 2 (a). By passing the blue light shown in the curve C in FIG. 2 (Vj) through the filter 5 installed in FIG. 2 and having the characteristics shown in the curve α in FIG. Also, the other light source 4
is a fluorescent lamp that is a mixture of blue and red fluorescent materials, and has the characteristics shown in Figure 2 (river curve). It is possible to emit light of color 1'f' as shown in FIG.
これによって両光源3.4を同時に点灯することによシ
十分な光量の−y色光が取出せる。As a result, a sufficient amount of -y color light can be extracted by turning on both light sources 3.4 at the same time.

light up at the same time. As a result, the exposure position of the original iA and the light #3.4 are directly illuminated, so a sufficient amount of blue light can be extracted, and when red light is extracted, the light source 4 is placed at the position where the original A is directly irradiated. , and the reflector 1 of the light source 3
The light sources 3 and 4 are fully rotated to the position where the light source 4 reflects the light from the light source 4 toward the document A side. As a result, the exposure position of the document person is illuminated by the direct light from the light source 4 and the reflected light from the first reflecting plate 10, so that sufficient light (red light) can be obtained.
これによって青色、緑色及び赤色の3JM色が同一の光
量で色分解可能になる。This makes it possible to separate the 3JM colors of blue, green, and red with the same amount of light.

費電力も少なくできる。Effects of the Invention As described in detail above, this invention uses two fluorescent lamps with different fluorescent materials as light sources, and illuminates a document by lighting these light sources singly or simultaneously, and does not light when they are turned on alone. A reflection means installed in the light source reflects a portion of the light toward the document side, increasing the amount of light emitted.This eliminates the lack of light intensity during illumination, and only requires two light sources. Power consumption can also be reduced.
