    The invention relates to automation and can be used to read reproductions from flat originals.
    The aim of the invention is to improve the accuracy of device operation.
    The drawing shows a diagram of the device.
    The device contains a radiation source 1, a beam 2 of light, a collimator 3, an extended luminous flux 4, a mirror drum 5, an electric drive 6, a scanning lens 7, the original 8, a scanning line 9, a cylindrical lens 10, a diffusing plate 11, a light mixer 12, a fiber-optic converter 13, photodetector 14.
    The device works as follows.
    The original to be read is slowly pulled in the direction of the arrow, and thus the line is read line by line. Owing to the Kaye effect, the highly concentrated incoming light emerges from the original from the lower side with a more or less wide mace. Diffusion occurs on the grains of the layer; - scon and depends on their size and distribution. The cylindrical lintel 10 located below the scanning line 9 focuses the light onto the diffusing plate II. If there is no scattering (the original is not crossed, the density is zero), then a small focal point is formed on the scattering plate. With a stronger darkening, i.e., more dispersion, the focused spot, on the contrary, takes the 4th form of an elongated

    ellipse, the major axis of which is parallel to the line 9 sweep. The diffuser plate 11 forms the front surface of the light mixer 12, which consists of a parallelepiped made of a transparent material, such as glass or plexiglass, and the outer surfaces of which are polished.

    The scattered light emerging from the diffusion plate 11 in this body, due to multiple reflections, leads to its lower surface, which to a greater extent, regardless of the shape of the spot on the scattering film, is illuminated over a large surface. This reduces or eliminates the effect of the Kaye effect, and so much so that, in practice, it does not interfere anymore. On the bottom side of the luminaire 12, the light enters the transducer, which consists of a large number of irregularly arranged optical fibers, Mixer 2 has a beam of light in the shape of the lower part of the light mixer 12, and at the other end is combined into a section that corresponds to the shape of the sensitive layer of the photoreceiver 14. It produces electrical output signals, which are largely free from the Kaye effect. Invention Formula
