  Then, the storage tape reel is removed from the unit frame of the component supply unit, and the end of the storage tape 1 that has been wound around the storage tape reel (referred to as “old storage tape 1” for convenience) is almost near the end. The part is cut as shown in the upper left part of FIG. That is, the old storage tape 1 is cut in a direction perpendicular to the feeding direction at an intermediate position between the storage unit 2 and the storage unit 2. That is, the carrier tape 3 and the cover tape 4 are cut at the same position (intermediate position between the storage portion 2 and the storage portion 2) in a direction orthogonal to the feed direction.

  On the other hand, the carrier tape 3 and the cover are provided at the intermediate position between the storage portion 2 at the start end and the storage portion 2 next to the start end portion of the new storage tape 1 that is additionally wound around the storage tape reel. The tape 4 is cut in a direction orthogonal to the feed direction.

  Next, the cover tape 4 covering the starting end storage portion 2 is peeled off, and the cover tape 4 is cut in a direction perpendicular to the feed direction at a position beyond the starting end portion beyond the starting end storage portion 2.

  Further, at the start end of the carrier tape 3 of the new storage tape 1 processed as described above, the length of the cover tape 4 is approximately equal to the length between the start storage 2 and the next storage 2. The both end portions are cut off from the starting end portion of the carrier tape 3 by being longer than the cutting position by the length of about two of the feed holes 5. That is, as will be described later, the electronic component 6 at the end of the storage tape 1 that is added to the storage 2 at the start of the new storage tape 1 that is added so that the storage 2 at the start does not store electronic components is stored. Since the storage portion 2 is fitted so that the both end portions of both storage tapes 1 are not overlapped, the both end portions are held by the length of about two of the feed holes 5 so as not to overlap. Cut off from the beginning of the tape 3. At this time, only the carrier tape 3 of the new storage tape 1 to be added is cut off, and the cover tape 4 is peeled up to an intermediate position between the starting storage portion 2 and the next storage portion 2 and is not cut away.

  Next, with the old storage tape 1 and the new storage tape 1 being processed as described above, the connecting operation of the old storage tape 1 and the new storage tape 1 already loaded in the component supply unit ( (Splicing) will be described.

  First, as shown in FIGS. 2 to 4, the storage portion 2 at the end of the old storage tape 1 is fitted and stored from above in the storage portion 2 at the start of the new storage tape 1 in which the electronic component 6 is not stored. That is, the storage portion in which the electronic component 6 at the end of the storage tape 1 added to the storage portion 2 at the start end of the new storage tape 1 to be added is configured so that the storage portion 2 at the start end does not store electronic components. 2 are fitted so that the both end portions of both storage tapes 1 are not overlapped, so that the electronic components are continuously stored in the storage portion 2 and can be supplied continuously. At this time, as shown in FIG. 3, the rear end surfaces of the ear portions 3 </ b> A at both ends opposed to each other across the side-by-side storage portion 2 in which the feed hole 5 of the old storage tape 1 is formed and the feed hole of the new storage tape 1 The ear portions 3A and 3B at both ends are fitted so that they do not overlap with each other so that the front end surfaces of the ear portions 3B at both ends facing each other with the storage portion 2 arranged side by side are formed, and the old The cover tape 4 of the new storage tape 1 is superposed on the cover tape 4 of the storage tape 1 from above (see FIG. 4).

  Next, the structure of the connecting sheet for connecting and fixing the new storage tape 1 and the old storage tape 1 does not matter, but as shown in FIG. 5, the ear portions 3A at the both ends of the old storage tape 1 and the new storage tape 1 Are connected by the connecting sheet 10. That is, the connection sheet 10 with the adhesive applied on the back surface is folded back, and the new storage tape 1 and the old storage tape 1 are connected and fixed so as to sandwich the ear portions 3A and 3B.
