2. Description of the Related Art Conventionally, as shown in FIGS.
The electronic component lead wire 1 is obtained by welding a tab 1b made of aluminum to a lead material 1a, pressing the tab 1b to form a flat plate portion 1c, and then trimming by press working to make the outer shape constant. It is made by molding,
Further, in this case, the electronic component lead wires 1 are individually manufactured one by one, and after the production, each electronic component lead wire 1 is shipped in a separated state.

Further, as shown in FIGS. 10 and 11, a sharp projection 1e is often formed by welding on the welded portion 1d between the lead material 1a and the tab 1b, and the flat plate portion 1c is further formed.
A burr 1f is formed by press working on the outer peripheral portion of, and the projections 1e and the burr 1f are in a very hard state because aluminum is hardened by working.

On the other hand, the supply of the electronic component lead wire 1 is generally performed in the form of a spiral vibrating parts feeder (not shown).
After the lead material 1a is aligned so as to face downward, as shown in FIGS. 12 and 13,
Two guide members 2 arranged at a predetermined interval
The lead material 1a is inserted into the gap 2a between them, and the lead material 1a is conveyed by gravity or by vibrating the two guide members 2 (in the case of a straight vibrator) in the direction of arrow A, and a tab attaching device (not shown) or the like. It was done by the method of supplying to.

However, when the electronic component lead wire 1 is transported by the guide member 2, the electronic component lead wire 1 is transported in the direction of arrow B or C, while rotating slightly, but in the direction of arrow A. Is the edge 2b of the guide member 2
However, the welding portion 1d is conveyed while rubbing the edge 2b, and the very hard protrusion 1e scrapes off the surface of the edge 2b, and the guide member 2 becomes unusable at an early stage. When used with the surface roughness of the edge 2b increased, the electronic component lead wire 1
However, there is a defect that the rough edge 2b is caught and the smooth supply cannot be performed. Therefore, conventionally, there has been a drawback that the guide member 2 must be removed fairly frequently to rework the edge 2b smoothly or the guide member must be replaced.

14 and 15, in the production of the electrolytic capacitor element, the flat plate portion 1c of the electronic component lead wire 1 is brought into close contact with the aluminum foil 3 and the flat plate portion 1c is attached to the aluminum foil 3 by a gusseting process or the like. Although it is fixed (so-called tab attachment), if the surface with the burr 1f is fixed in contact with the aluminum foil 3, the burr 1f damages the aluminum foil 3 or breaks the aluminum foil 3 (direction of arrow D). Then, there is a drawback that the electric performance of the electrolytic capacitor element is significantly deteriorated.

In order to prevent the aluminum foil 3 from being scratched, the surface of the flat plate portion 1c on which the burrs 1f are not present is the aluminum foil 3
Although it can be prevented by contacting with, and carrying out a boring process, as shown in FIG. 13, the flat part 1c of the electronic component lead wire 1 supplied while rotating in the direction of arrow B or C is fixed and supplied. Aluminum foil 3 on the surface without burr 1f
It is extremely difficult to make a tab attachment by closely adhering to, and especially in the production of a small-sized electrolytic capacitor element, the flat plate portion 1c of the electronic component lead wire 1 is further downsized, which is almost impossible.

In the conventional electronic component lead wire 1 which is supplied without determining the direction of the flat plate portion 1c, the probability that the surface of the flat plate portion 1c where the burr 1f is present contacts the aluminum foil 3 and is fixed is 50. %, There is a sufficient possibility that the burr 1f will bite into the aluminum foil 3 to damage it and deteriorate the electrical characteristics in that state. In an extreme case, the aluminum foil 3 is torn as a defective element in the direction of arrow D. There was a possibility that it would end up.
