摘要：
An image sensor unit includes: a light guide reflecting light rays entering through a first light entering surface and a second light entering surface provided at both ends thereof, by a reflection surface to make the light rays exit through a light exiting surface and illuminates an original; a first light source provided near the first light entering surface; a second light source provided near the second light entering surface and different in wavelength from the first light source; and a first reflection part and a second reflection part provided on the reflection surface and composed of dot patterns constituted of two kinds of dots different in spectral reflectance.
