PROBLEM TO BE SOLVED: To prevent an unidentified electronic part from being erroneously recovered by identifying an acceptable or a rejectable electronic part transported from a transport part by a part for identifying and recovering a reject and previously recovering a required number of following electronic parts on the transport part and returning these parts to an electronic part feed part prior to the recovery of a faulty electronic part. SOLUTION: An electronic part P transported from a manufacturing step is aligned one by one in an electronic part feed part A and is sent into the transport groove 11 of a transport part B. The electronic part P is identified for its compliance with standards at the terminal of the transport part B by a detecting pin and a sensor beam. Further, if a rejectable part is identified, a second electronic part P2 is firmly held by a reject holding means together with a faulty electronic part at the head. In addition, a terminal guide wall is allowed to slide sideways to open a suction/ discharge port 20 and a negative pressure is generated in the suction/discharge port 20 by a vacuum generator 29 for the part of good quality to suck 20-30 pieces of following electronic part P3 present within the coverage area of negative pressure suction function. Finally, the sucked electronic part P3 is forcibly transported to a recovery box 31 from a suction hose 28. |
