Abstract: PURPOSE:To properly adjust the quantity of light by varying the quantity of transmitted light and then moving the transmitted light quantity distribution into a proper range, and to decide that the milling rate sensor is abnormal unless the light quantity adjustment ends with the maximum and minimum values of the light quantity variation. CONSTITUTION:Rubbed rice 3 is passed through irradiation light from a light emitting element 16, grain by grain, and the milling rate sensor 1 detects the quantity of transmitted light that a light receiving element 17 receives and outputs the detected quantity to a milling rate controller 10. The controller 10 calculates a milling rate such as the threshold value of the transmitted light quantity distribution 4. Further, a light quantity controller 18 as part of the controller 10 has an output circuit 19 which inverts the output voltage to adjust and control the quantity of light of the element 16 automatically and adjusts the quantity of light of the element 16 so that the unpolished rice mean block value of the distribution 4 is put in a light quantity adjustment set range (proper range) L by varying the quantity of light; when the mean block value enters the range L, the adjustment control is finished. When the quantity of light does not enter the range L while varying from the minimum value to the maximum value, abnormality is decided and the milling rate control by the sensor 1 is not performed.
