First, when the fruits and vegetables A placed on the conveyor 2 are carried into the light-shielding chamber 40, FIG.
As shown in FIG. 4, when the fruit and vegetable product A is displaced upward and leftward and rightward by displacing the front-group-side linear light-shielding bodies 41 hanging from the opening 40 a so as to be allowed to pass therethrough. The light-shielding bodies 41 are displaced (or retracted) along the outer peripheral surface of the fruit and vegetable A, thereby reducing the contact resistance applied to the fruit and vegetable A and concealing a gap formed on the outer peripheral surface of the fruit and vegetable A. I do. At this time, the rear group side linear light blocking members 41 are suspended in the closed state, and the light shielding state is maintained.

に検査することができ、精度の高い検査が行える。As described above, when the fruits and vegetables A placed on the conveyor 2 are carried in and out of the light-shielding chamber 40, the linear light-shielding body 4 vertically provided at the openings 40a and 40b of the light-shielding chamber 40 is provided.
Since the remaining space excluding the portion through which the fruit and vegetable A passes can be shielded as much as possible by 1..., External light can be reliably prevented from entering the light shielding chamber 40. In addition, since only the light (for example, reflected light and transmitted light) of the light source 49 irradiated on the fruit and vegetable A can be received by the imaging cameras 45 to 48, the fruit and vegetable A can be accurately detected without being affected by external light. Inspection can be performed with high accuracy.
