The above-mentioned mirror body 24 is formed to have a length and a width that reflect the side peripheral surface of the fruit and vegetable A obliquely upward, and as shown in FIG. 4, for example, a metal plate (stainless steel), a resin film, or the like. For example, a metal (silver) is applied or vapor-deposited on the entire surface of the belt-like base 24a formed of a flexible thickness or material such as synthetic rubber, so that a reflective surface is formed on the entire surface of the belt-like base 24a. 24b are continuously formed, and the reflectance of the reflection surface 24b is set to be substantially equal to the image of the fruit vegetable A directly taken by the imaging camera 45.

The mirror body 24 is supported by a support frame 25 on the side of the inspection section B.
A motor 28 with a speed reducer (e.g., a motor having a rotation amount detecting function such as a pulse motor) which is stretched between rolls 26 and 27 which are supported by The surface 25b rotates intermittently by the amount of rotation facing the side peripheral surface of the fruit or vegetable A. Further, for example, by operating a switch, rotating based on detection by a sensor, rotating at predetermined time intervals, or the like,
4 may be rotated by an arbitrary amount.

The motors 28 on both sides may be synchronously rotated in the same direction or different directions, or may be rotated at different speeds. The rotation of the motors 28 may be controlled, or gears, belts, chains, etc. may be used. The mirrors 24 may be rotated in conjunction with each other.

On the other hand, the reflection surface 24 on the return side of the mirror body 24
The wiping brush 29 in contact with b rotates in a direction in which the motor 28 (or another motor, manual operation) removes foreign matters such as dirt and dust adhering to the reflection surface 24b.

The wiping member 30 (for example, synthetic rubber, non-woven fabric, sponge, water-absorbing body, etc.) in contact with the rear-side reflecting surface 24b
Is to remove dirt, water droplets, and chemicals remaining on the reflecting surface 24b of the mirror body 24 by wiping or adsorbing them using the rotational force of the mirror body 24. The reflecting surface 24b of the mirror body 24
Is wiped by the wiping brush 29 and the wiping member 30, or by one of the means, to restore the reflection surface 24b to the original reflectance.

The wiping brush 29 and the wiping member 30 are reciprocated up and down or left and right to move the reflecting surface 24 of the mirror body 24.
b may be wiped, and at the time of wiping, a cleaning liquid (for example, water, a cleaning agent, a chemical, or the like) may be sprayed on the reflection surface 24b.

The illustrated embodiment is configured as described above, and the operation of inspecting and sorting the fruits and vegetables A by the image processing device 5 will be described below. First, as shown in FIG. 1, when a large number of fruits and vegetables A are transferred from the sorting conveyor 3 to the sorting conveyor 4, a pressing belt 9 laid between the conveyors 3 and 4 is pressed to a predetermined position and at a predetermined interval. , And sequentially transfer.

Next, the supporting members 19 project from the conveying surface, and the fruit vegetables A placed on the supporting rollers 16 of the sorting conveyor 4 are conveyed while being supported by the supporting members 19 in a substantially horizontal posture. 2 and 3, in the first imaging region of the inspection unit B, the front side peripheral surface of the fruit and vegetable A placed on the support members 19, and the mirror body constituting the reflector 7 as shown in FIG. 24,
The left and right peripheral surfaces of the fruit and vegetable A reflected by 24 are imaged by an imaging camera 45 constituting the image processing device 5, and the image data is stored in the device main body 51.

At the time of imaging, the reflection surface 24 of the mirror 24
If the reflectance decreases due to dirt or dust or dirt adhering thereto, the mirror 24 is rotated during the work or after the work is completed, and the reflecting surface 24b having the predetermined reflectance is changed to a fruit vegetable. A side peripheral surface.

Thereafter, the support member 19 is immersed, and the fruit and vegetable A is placed on the support roller 16 and is moved from the first image pickup area to the second image pickup area.
While being transported to the imaging area, the fruit and vegetable A is turned upside down (for example, approximately 180 degrees) by the rotating machine 6. In addition, the front and back may be reversed in the first imaging region.

Again, the fruit and vegetable A is supported in a substantially horizontal posture by the support member 19, and the support member 19 is supported in the second imaging area.
Are imaged by the imaging camera 46 on the back side peripheral surface of the fruit and vegetable A placed in... And the image data is stored in the apparatus main body 51. Thereafter, the support member 19 is immersed, and the fruit and vegetable A is placed on the support rollers 16 and transported.

On the other hand, the image data picked up by the imaging cameras 45 and 46 is compared with the class data stored in the apparatus main body 51, and the class is comprehensively determined. When the fruit product A is conveyed, the unlocking device 53 is operated, the support roller 16 is swung to the release position, and the fruit product A is released to the predetermined sorting unit for each class. The non-standardized fruit and vegetable A is released to another sorting unit and collected. In the same manner, fruits and vegetables A... Conveyed by the sorting conveyor 4 are sorted for each grade.

As described above, when the reflectance of the belt-shaped mirror 24 is reduced, the mirror 24 is rotated by an arbitrary amount so that the reflecting surface 24b having a predetermined reflectance is placed on the side peripheral surface of the fruit and vegetable A. Since they are opposed and reflected, the mirrors 61, 6
The labor and work of wiping or replacing the light receiving member 6 or the light receiving member 62 can be omitted, and the reflectance suitable for imaging can always be stably obtained. Based on the captured image data, the grade of the fruit and vegetable A can be determined fairly, and the work of sorting by grade can be performed accurately.

Further, since the mirror body 24 is wiped by the wiping brush 29 and the wiping member 30 to recover the state before the reflectance is lowered, the predetermined reflectance can be maintained, and the imaging condition is always constant. Therefore, the class of the fruit and vegetable product A can be determined fairly and accurately, and the determination accuracy and reliability are improved.

Further, the fruit and vegetable A reflected by the mirror body 24
The left and right peripheral surfaces are imaged by the single imaging camera 45, so that a camera for imaging the left and right peripheral surfaces of the fruit and vegetable A is not required.
In the imaging region, when the fruit and vegetable A is turned upside down by the rotating machine 6, the imaging camera 46 for imaging the back side of the fruit and vegetable A becomes unnecessary, so that the number of cameras to be installed can be reduced, and the entire apparatus can be reduced. Can be simplified and the production cost can be reduced.

FIG. 5 shows another embodiment in which the substantially disc-shaped mirror 31 is rotated to reflect the image of the vegetable A.
The mirror 32 is rotated at an arbitrary angle (for example, 1/4) by driving the motor 32 directly connected to the center portion on the back side of the camera, and the reflecting surface 31b (approximately 1/4) having a predetermined reflectance is converted to fruit vegetable A.
