PURPOSE:To prevent a conveyor chain from falling as well as a member from being raptured by making larger a width of the lower end of a notched portion of a projection piece provided on the conveyor chain for supporting electronic parts as well as an interval between the lower end of the notched portion and the drum peripheral surface than a diameter of a large diameter part of each of the electronic parts. CONSTITUTION:In conveying electronic parts 5 while supporting a lead wire 8 of the electronic parts with right and left projection pieces 12, 12 of a conveyor chain body 9, even if a body part 6 having a large diameter of the electronic parts is positioned at a notched portion 13 in the projection piece 12, the electronic parts 5 are prevented from floating beyond the chain body 9 since width S1 of the lower end part of the notched part 13 is larger than diameter R of the large diameter part 6 of the electronic parts 5. In addition, even if the projection piece 12 is in such a state inserted into a guide groove 16 of a drum 7 serving to change the conveyance direction, the chain is prevented from being pushed out by the parts 5 since an interval S2 between the peripheral surface 15 of the drum 7 and the electronic parts supporting surface 14 located in the lower end of the notched portion 13 of the projection piece 12 is larger than the diameter R of the parts large diameter part 6. Thus, the chain can be prevented from falling off as well as electronic parts prevented from being raptured. |
