A light shielding member is provided to block the direct illumination light flux from the illumination light source to the document surface, and the light flux from the illumination light source is once reflected on the reflection member, and the document surface is illuminated by this reflected light -λ-. This allows the illumination light source to be brought closer to the outside of the imaging optical path than in conventional illumination systems, and therefore it is possible to provide an inter-wall system that is more compact than the illumination systems of conventional recording devices. be.

The illumination is performed using reflected light obtained by reflecting the luminous fluxes of the illumination light sources 3a and 3b by the reflecting plates 5a and 5b, respectively. Illumination light source 3a, 3
b is arranged at a position where the specular reflection of the direct illumination light from the illumination light sources 3a and 3b onto the document surface (not shown) on the document table enters the optical imaging system; Direct illumination light to a document (not shown) on Ω is blocked by light shielding plates +a and lIb. On the other hand, the reflecting plates 5a and 5b are arranged at positions that satisfy the following conditions. That is, among the illumination light beams from the virtual images 3/, 6, and 31b caused by the reflection plates 4a and 5b of the illumination light sources 3a and 3b, specularly reflected light from the document surface (not shown) on the document table Ω is optically reflected.

A document (not shown) on a document table is recorded on a recording medium (not shown) by an optical imaging system (not shown) located at the back side of the paper via a reflective mirror (2) provided at an angle. In this case, the imaging optical path is bent by the reflecting mirror B in order to downsize the recording device. Therefore, in order to further downsize the illumination system, the reflection plates 5a and 5b are arranged as close as possible to the optical axis (center axis) of the optical imaging system. In this case, the reflector, q
The lower ends of a and 5b extend nearly above the document table Ω.

In this case, the positional relationship between the illumination light sources 3a and 3b and the reflection plates 5a and 5b is such that out of the illumination light flux from the respective virtual images 3/a and 31b generated by the reflection plates a and 5b of the illumination light sources 3a and 3b, only a portion of the illumination light beam from the document table is used. The specularly reflected light from the document surface (not shown) on Ω is reflected by the optical imaging system/
