Problems solved by technology

[0009] When using a fluorescent tube light source, there is a problem that it takes a long time from lighting up to stabilizing to a readable amount of light
In addition, when a light source using a fluorescent tube is used to ensure a wide irradiation area capable of irradiating the entire document, there is a problem that the size of the light source is increased, and the size of the image reading device accompanying the increase in the size of the light source is increased.
[0010] In addition, when using an LED light source, the original image can be read immediately after lighting, and compared with the case where a fluorescent tube is used, the image data can be reduced. However, since the irradiation area of ​​each LED is limited, it is necessary to install multiple LEDs to ensure a wide irradiation area that can illuminate the entire document, so there is an increase in the size of the light source and an increase in the size of the image reading device accompanying the increase in the size of the light source. The problem
[0011] In addition, when a plurality of LEDs are used in a single light source, there is a reduction in the quality of image data due to dispersion of the light amount of each LED, and the image reading device The problem of high manufacturing cost
