Claims (7)

[Claims] 1. An inspected component sent out from an inspection process is intermittently rotated while intermittently rotating a disk-shaped rotating body in which a large number of accommodation holes for accommodating an inspected component are circularly arranged. Then, the inspected parts that have been stored are selectively sucked and discharged from the non-defective product outlet and the defective product outlet provided at the moving path of the accommodation hole after the inspection processing determination time. Inspection part distribution method characterized by performing. 2. A disk-shaped rotator having a large number of accommodation holes for accommodating inspected components arranged in a circle, a suction passage for sucking the inspected components sent out from the inspection process into the accommodation holes, and A motor for intermittently rotating the disk-shaped rotator, a non-defective product outlet and a non-defective product outlet provided in correspondence with the storage hole, and a non-defective product outlet for inspecting a component in the storage hole according to a test result. Or a discharge control unit for selectively sucking and discharging the defective product from the defective product discharge port, and the inspected component stored in the accommodation hole is supplied from the non-defective product discharge port or the defective product discharge port after the inspection processing determination time. The inspection component distribution device, wherein each of the discharge ports is provided at a position separated by a predetermined angle from the suction passage so as to be discharged. 3. The inspection component sorting apparatus according to claim 2, further comprising means for suction-holding the inspected component at a predetermined position in the accommodation hole. 4. An inspection error discharge port for sucking and discharging an inspected part determined as an inspection error, wherein the discharge control unit performs inspection from the non-defective product discharge port, the defective product discharge port, or the inspection error discharge port. The inspection component sorting apparatus according to claim 2, wherein the used component is selectively sucked and discharged. 5. A forced discharge port for forcibly sucking and discharging the inspected parts that cannot be discharged, wherein the discharge control unit is configured to output the non-defective product, the defective product, the inspection error, or the compulsory discharge. The inspection component sorting apparatus according to any one of claims 2 to 4, wherein the inspected component is selectively sucked and discharged from the outlet. 6. A memory in which a number is assigned to each of the storage holes and the inspection result is stored in correspondence with the number, and the discharge control unit controls the storage hole to stop at each of the discharge holes. 6. The component inspection distribution device according to claim 2, wherein the memory is referenced to determine whether or not to discharge the inspected component from each of the outlets. 7. A component for causing an inspection component to fly by sucking, performing image processing on image data of the inspection component captured during flight, and performing an appearance inspection, and selecting the inspected component based on the inspection result. In the inspection device, a disk-shaped rotating body in which a large number of receiving holes for housing inspected components are arranged in a circle, a housing for rotatably housing the disk-shaped rotating body, and a housing provided in the housing and transmitted from an inspection process. A suction passage for sucking the inspected component to be sucked into the accommodation hole, a motor for rotating the disk-shaped rotating body by one accommodation hole each time the inspected component is sucked into the accommodation hole, and A non-defective outlet and a non-defective outlet provided corresponding to the hole, and selectively inspecting and discharging the inspected parts in the receiving hole from the non-defective outlet or the defective outlet according to the inspection result. And a discharge control unit that,
Each of the outlets is provided at a position separated by a predetermined angle from the suction passage so that the inspected component taken into the housing hole is discharged from the non-defective product outlet or the defective product outlet after the inspection processing determination time. A parts inspection apparatus characterized by comprising:
