There is a method and an apparatus for inspecting the internal quality of cored fruits and vegetables disclosed in Patent Document 1 to be discriminated by the discriminating unit. However, there is no disclosure of the configuration and idea of displacing the light irradiation position in the axial direction, and only the same peripheral surface of the cored fruits and vegetables is irradiated with light, so only the quality of the portion through which the light is transmitted can be determined. . Moreover, if the core of the part irradiated with light is large, the internal quality of the cored fruits and vegetables cannot be accurately determined.

  Further, the same fruits and vegetables that are rotated by the rotational force of each fruit and vegetable placing portion while measuring the light projected from the irradiation means while moving the fruits and vegetables placed between adjacent fruit and vegetable placing portions in the transport direction. Patent Document 2 that irradiates the peripheral surface, receives measurement light transmitted through the fruits and vegetables from the gaps between the fruit and vegetable placement parts, and receives the measurement light, and analyzes the spectrum of the received measurement light by the quality determination means to determine the quality There is a fruit and vegetable quality measuring device. However, only the measurement light transmitted toward the gaps between the fruit and vegetable placement parts can be received, and only the quality of the central part of the fruit and vegetables through which the measurement light passes can be determined.

In addition, the cylindrical cell is rotated around the center of the circle, and the near infrared irradiation device is moved in the length and height directions of the cell to irradiate the whole raw tea leaf in a dispersed state in a spiral. Thus, there is a tea leaf component analysis method and apparatus of Patent Document 3 to be measured. However, it is impossible to specify which part of the raw tea leaves was irradiated with near infrared rays, and it is impossible to determine a measurement standard, so an accurate measurement result cannot be obtained.

  Next, as shown in FIGS. 2 and 5, the root Aa of the green onion A held by the holding frame 11 is inserted into the center of the rotating frame 23 waiting at the measurement start position, and on the stem Ab of the green onion A. Is inserted between the detection light irradiation device 3 and the transmitted light detection device 4, and the root Aa of the green onion A that is in contact with the restricting portion 11a is used as the inspection reference position. The detection light irradiation device 3 and the transmitted light detection device 4 are sequentially moved to positions facing the inspection portions a to f set on the stem Ab.

  When the detection light irradiation device 3 and the transmitted light detection device 4 are moved or stopped to a position facing the first inspection portion a set on the stem Ab, the rotation device 6 is driven to rotate, and the detection light irradiation device 3 and the transmitted light detection device 4 are rotated to respective inspection angles set at a predetermined equal angle with respect to the circumferential direction around the axis of the green onion A.

  The detection light B projected from the detection light irradiation device 3 is irradiated from a plurality of inspection angles to the inspection portion a set on the stem Ab and transmitted to the outside of the inspection portion a. Each transmitted light C... Is continuously detected by the transmitted light detection device 4 for each inspection angle, and based on the detection information output from the transmitted light detection device 4, the circle of the inspection part a is detected for each inspection angle. The content of the component contained in the circumferential direction is calculated by the distribution calculation device 7.

  Similarly to the above, when the detection light irradiation device 3 and the transmitted light detection device 4 are moved or stopped to positions facing the second to sixth inspection portions b to f set on the stem Ab of the green onion A The detection light B projected from the detection light irradiation device 3 is rotated at a predetermined equal angle with respect to the circumferential direction around the axis of the green onion A, and a plurality of each of the inspection portions b to f is detected. A plurality of transmitted lights C irradiating from the inspection angles and transmitted toward the outside of the inspection portions b to f are continuously detected for each inspection angle by the transmitted light detection device 4 and transmitted light detection is performed. Based on the detection information output from the device 4, the distribution calculation device 7 calculates the content of the contained component included in the circumferential direction of each of the inspection portions b to f for each inspection angle.

  In addition, the average value of the content component in the circumferential direction is calculated for each inspection portion a to f, and the average value is stored as the measurement value of the content component in the length direction.

The transmitted light detection device 4 is rotated clockwise, and the detection light B projected from the detection light irradiation device 3 is irradiated to the inspection portion b from a plurality of inspection angles. Hereinafter, similarly to the above, the onion A and the transmitted light detection device 4 are rotated counterclockwise in synchronism with a predetermined inspection angle at positions facing the inspection portions cf, so that the onion A or the transmitted light detection device 4 Since the amount of rotation is smaller than the rotation of either one and the operation time required for forward / reverse rotation is shortened, the measurement capability can be improved. Further, the transmitted light C transmitted toward the outside of the inspection portions a to f is detected at each angle by the transmitted light detection device 4 that moves and rotates integrally with the detection light irradiation device 3.

  FIG. 8 shows a third embodiment in which the detection light irradiation device 3 and the transmitted light detection device 4 are paired, and a plurality of them are arranged in the circumferential direction at an angle corresponding to each inspection angle around the axis of the leek A. The position which shows the measuring method, and each detection light irradiation apparatus 3 ... and each transmitted-light detection apparatus 4 ... which were arranged in multiple numbers on the same periphery oppose each test | inspection part af set on the stem Ab of the leek A Irradiating each detection light B ... projected from each detection light irradiating device 3 ... from each of a plurality of irradiation directions to each inspection portion af set on the stem Ab, Since each transmitted light C... That is transmitted toward the outside of the inspection portions a to f is detected by each transmitted light detection device 4..., Substantially the same operations and effects as the above embodiment can be achieved. Further, the detection light irradiation device 3 and the transmitted light detection device 4 can be rotated around the axis of the leek A, or the operation of rotating the leek A itself can be omitted. Improvements can be made. A plurality of transmitted light detection devices 4 may be provided at an angle corresponding to each inspection angle.
