The rice grain S for measurement is put in from the supply port 3a provided in the case body 3. As shown in FIG. 7, the introduced rice grains S abut against the conical diffusion part 4b, and the disc 4 around the diffusion part 4b.
It is dispersed on a and falls. For example, the rice grain S dropped on the disk 4a toward the disk center side (position A) of the width-approaching means 10 is transferred by the rotation of the disk 4 in the arrow Y direction while being almost stationary on the disk due to the inertial force (Fig. 8). The transferred rice grains S contact the guide plate 11b and are transferred to the rotation direction side of the disk along the guide plate 11b.

The rice grains S thus fed from the supply port 3a are put in the respective grain holding holes 4a. Even if rice grains come into contact with the guide plate 10a and are not transferred into the granular material holding hole 4a and are transferred, the guide plate 1
It comes into contact with 0b, 10c and surely enters any of the granular material holding holes 4a.

When a plurality of rice grains are overlapped in the granular material holding hole 4a, the rice grains on the upper side are
Excluded inward on the disk. Further, the rice grains located between the adjacent granular material holding holes 4 are also removed inwardly on the disc by the brush 15. The removed rice grains S are regulated by a plurality of guide plates 11a, 11b, 11c, 11
It comes into contact with d, is transferred along the guide plate to the rotational direction side of the disk, and is then transferred along the guide plate 12a and is returned to the accumulating portion 16. In addition, since the retention section 16 is provided with the delivery port 13 as described above, a large amount of rice grains can be retained and can be delivered in appropriate amounts. Therefore, in the widthwise portion 52 on the disk formed by the guide plates 10a, 10b, 10c, the rice grains do not become clogged with the weir portion 14.

The rice grains which have entered the respective grain holding holes 4a under the action of the guide plates 10a, 10b, 10c and the guide plates 11a, 11b, 11c, 11d are detected by the optical detecting section 23.

The transferred rice grains S receive the irradiation light from the light sources 22a, 22b, 22c and the light sources 26, 27 in the first optical detection unit 23a, and emit the light emitted from the rice grains S to the RGB line sensor 24 and the RGB line. It is detected by the sensor 29. The RGB line sensor 24
And the detection data detected by the RGB line sensor 29 are sent to the first image processing unit 38 and the second image processing unit 39, respectively, and the surface of the rice grain is processed by the first image processing unit 38 and the second image processing unit 39. And the side surface are respectively pixel-imaged and the data are sent to the discrimination unit 41.

The rice grains S that have passed through the first optical detecting section 23a are transferred to the second optical detecting section 23b, and the transferred rice particles S are transferred to the light sources 32, 33 and the light source in the second optical detecting section 23b. The rice grain S
The light emitted from the RGB line sensor 35 is detected. The detection data detected by the RGB line sensor 35 is sent to the third image processing section 40, and the pixel image data of the back surface of the rice grain is sent to the discrimination section 41.

The CPU 46 of the discriminating section 41 controls the rice grain S
Each pixel image of the front surface, the side surface, and the back surface of the device is fetched through the input / output circuit 45, the area and the volume are calculated and compared with the comparison data stored in advance in the ROM 47, and the color and the light amount are also compared. Compare with the data. Then, the quality of the rice grain is determined by comprehensively judging the results of these comparisons. In this way, the quality of the rice grain is determined, and the number is stored in the RAM 48 while counting the number of each quality. When the measurement is completed, the RAM4
The ratio of each grade is calculated based on the count number of 8, and the calculation result is transmitted to the printing unit 50 and the display unit 51.

According to the present invention, the disks are arranged in a horizontal state, not in an inclined state, and the bottom 4c of the granular material holding hole 4a is provided.
Since the rice grains are flat, the rice grains are horizontally transferred to the optical detecting section in each of the granular material holding holes 4a. Therefore, the light from the front surface, the side surface, and the back surface of the rice grain can be accurately incident on the light receiving sensor, and an accurate pixel image can be obtained.

In the above embodiment, the grains to be measured are rice grains, but the present invention is not limited to rice grains, and it is necessary to determine the shape and color of each grain of a granular material such as resin pellets and chip capacitors. Any granular part can be applied. In that case, the design of the optical detection unit and the like is changed as appropriate.

In the above embodiment, the shape of the granular material holding hole 4a is open on the peripheral side of the disk 4, but it may be closed. As shown in FIG. 9, the dam portion 14 may be provided so as to stand upright on the disk peripheral edge side of the opening in the granular material holding hole 4a. When the granular material holding hole 4a is closed as described above, the discharging unit for discharging the rice grains from the granular material holding hole 4a may be a suction method of sucking from the opening side of the granular material holding hole 4a.

In the above embodiment, each guide plate is formed integrally with the case body 3, but it is not formed integrally with the case body 3 and the upper parts of the guide plates are connected to each other to form the base. It may be fixed on the table 5.
