とができない問題点を有するものであった。By the way, in order to match the standard color plate to the particles based on the raw material particles to be color sorted, it is necessary to replace the standard color plate coated in dozens of different colors each time, or to use the standard color plate as a transparent body on the back side. A technique is known in which a lamp is provided and the reference color plate is adjusted by increasing or decreasing the photoelectric power of the lamp, but it is troublesome to replace the reference color plate each time the raw material particles differ, and it is difficult to select the reference color plate. It took a lot of time to do this, and it was a hassle to store it. In addition, in devices that adjust the reference color plate by increasing or decreasing the light intensity of the lamp, some raw material particles may not be able to be adjusted to the corresponding reference color, making it impossible to completely satisfy the sorting performance of all granular materials. However, there were some problems.

本発明の構成を第１図に基づき説明する。Operation With the above configuration, the plurality of lamps are colored, for example, red and green, and the amount of light from both lamps is projected onto the dichroic mirror. As shown in Figure 3, a dichroic mirror has a characteristic that, with a wavelength of 590 nm as its boundary line, longer wavelengths are transmitted through the dichroic mirror surface, and shorter wavelengths are reflected. The amount of light emitted from the green lamp passes through the dichroic mirror and hits the transmission plate of the reference color plate, and the amount of light emitted from the green lamp is reflected by the dichroic mirror and sent to the transmission plate, where each color is combined into a single color. The amount of light received by the light-receiving element and the amount of light obtained by irradiating the particles flowing down from the downflow gutter to the flow path are calculated with respect to the reference color plate which is adjusted to a color corresponding to the raw material particles. If there is a difference in color, the output signal from the control circuit that communicates the signal activates the injection nozzle device, and the particles of different colors are blown out of the normal flow trajectory by high-pressure air from the nozzle to be sorted out. By simply increasing or decreasing the light intensity of a plurality of lamps individually, the reference color can be arbitrarily adjusted to an appropriate standard color for the raw material particles. □Example The structure of the present invention will be explained based on FIG.
