  In this state, the upper jig body 22 is rotated with respect to the lower jig body 21 in the direction of the arrow in FIG. The truncated cone portion 61 a of the shaft 61 engages with the engagement hole 63 of the lower jig body 21. Thereby, the operation of the safety cover 58 becomes possible, and the safety cover 58 abuts against the upper surface of the lower jig body 21 and is displaced against the urging force of the urging member 62 (see the two-dot chain line in FIG. 7). Therefore, the cutting edge of the cutting cutter 57 protrudes from the slit 58a of the safety cover 58. Then, the first carrier tape T1A is cut at the cutting position P1 by the protruding cutting edge of the cutting cutter 57. The cut surface T1Aa at this time is shown in FIG.

  Next, the upper jig body 22 is rotated with respect to the lower jig body 21 around the hinge shaft 23 in the counter-arrow direction of FIG. As a result, the safety cover 58 is returned to the original position by the urging force of the urging member 62, and the cutting cutter 57 is accommodated in the safety cover 58. At the same time, the diameter of the truncated cone portion 61a of the operating shaft 61 is increased, so that the displacement of the safety cover 58 in the direction against the urging member 62 is restricted.

  Subsequently, the operation member 70 is pressed against the urging force of the urging member 76, and the oscillating member 71 of the first eject mechanism 50 is oscillated. Thereby, the 1st eject pin 45 (46-48) protrudes from the upper surface of the lower jig | tool main body 21, and the lower surface of 1st carrier tape T1A cut | disconnected in the cutting position is pushed up. Accordingly, since the first carrier tape T1A is detached from the left positioning pin 41, the first carrier tape T1A can be easily removed from the left placement surface 31a of the first cutting positioning portion 31.

  Next, the second carrier tape T2A connected to the first carrier tape T1A is cut from the right side of the lower jig body 21 so that the end thereof crosses the central cutting position P1, and the feed hole Hc is first cut. The right positioning pin 42 of the positioning unit 31 is engaged. At this time, the second carrier tape T2A engaged with the right positioning pin 42 is positioned at a position where the center of the feed hole Hc coincides with the cutting position P1.

  In this state, the safety cover 58 is displaced against the urging force of the urging member 62 by folding the upper jig body 22 with respect to the lower jig body 21 in the same manner as described above. 57 cutting edges protrude from the slits 58 a of the safety cover 58. The second carrier tape T2A is cut at the cutting position P1 by the protruding cutting edge of the cutting cutter 57. A cut surface T2Aa at this time is shown in FIG.
