- the present invention is not limited to the above-described embodiments, and various modifications and variations are possible.
- the form provided with the second ejection mechanism 60 that ejects the defective product from the turntable 20 has been exemplified.
- the present invention is not limited to this, and for example, a form without the second ejection mechanism 60 may be employed.
- the parts sorting apparatus 1 may eject the defective products from the turntable 20 immediately after the image pickup by the image pickup device 30 and the appearance inspection. Further, the parts sorting apparatus 1 may discharge the defective products from the linear feeder 10 or the turntable 20 immediately after the measurement by the measuring device 40 and the electrical property inspection.
- the defective product collection function may be arranged over the entire circumference of the turntable 20 and/or the entire lateral side of the linear feeder 10 .
- the inspection and selection controller 80 has a function of performing visual inspection of electronic components based on the imaging result from the imaging device 30, as an example.
- each imaging device 30 may have a visual inspection function.
- each of the imaging devices 30 may have a function of ejecting defective products from the turntable 20 immediately after the appearance inspection, as in the modification described above.
- the inspection and selection controller 80 has a function of inspecting the electrical characteristics of electronic components based on the measurement results from the measuring device 40, as an example.
- each measuring device 40 may have the electrical property inspection function.
- each of the measuring devices 40 may have the function of discharging defective products from the linear feeder 10 or the turntable 20 immediately after the electrical property inspection, as in the above modification.
