Claims (1)

[Scope of utility model registration request] The components are moved along a component transfer path by vibration, and a portion of the component transfer path is formed with a higher or lower light reflectivity than others, and an air jet hole is provided in the vicinity of this portion. A component front and back detection sensor equipped with a light emitter that projects a light beam to the part and a light receiver that receives the reflected light from the part, and whichever has a greater or lesser degree of light reflection, is provided. The part being transferred over the part with the side facing upward is allowed to pass through the part without blowing out air from the air ejection hole, since the light reception level of the part front/back detection sensor does not change beyond a predetermined value;
When the part is transferred over the part with the side with the smaller or larger light reflectance facing up, air is discharged from the air outlet when the light reception level of the part front/back detection sensor changes to a predetermined value or more. In the device for displacing parts from the parts transfer path by ejecting them, the part has a small hole formed in the transfer surface of the parts transfer path, and a colored material having a high or low reflectance of light is formed in the part. Or, a component front-back sorting device in a vibrating component feeder, characterized in that it is formed by filling a colorless solid substance.
