PURPOSE:To enable an automatic direction selection as well as to easily make a supply to a package material and a picking out from the package material by a method wherein a projection length of a lead in mutually opposite directions is set to be different in cutting off of the lead of a transistor. CONSTITUTION:A transistor wherein two of three leads are arranged in parallel and protrude from one plane of a sealing outer shell 1 and one lead protrudes from a plane opposed to this plane is cut off from a frame 5 at the point indicated by a dotted line. And then, the cut-off of the lead is performed so that a protruding length L1' of the 1st lead 2 may be larger than a protruding length L2' of the 2nd and 3rd leads 3, 4. And thereafter, this transistor is placed on a parts feeder and based on the difference of the L1' and the L2', a direction selection is automatically performed, and as a result, a containing to a magazine is easily performed. Namely, through this, an automation of a supply to the package material and picking-out from the package material can be easily performed. |
