Thereafter, the second carrier tape 900B enters the gap between the tape transport path 38 made by the first carrier tape 900A and the stopper member 31, and is transported toward the second sprocket 62. When the tip of the second carrier tape 900B pushes up the contact portion 31a, the stopper member 31 is rotated again against the urging force of the spring 36 as described above, and a new carrier tape 900 is formed by the stopper member 31. Intrusion is prevented.
- the operator removes the locking member 115 and rotates the cover member 110 together with the urging member 29 around the shaft portion 114, and between the second sprocket 62 and the third sprocket 63.
- the tape conveyance path 38 is opened. Then, the upper surface pressing member 28 is lifted and the carrier tape 900 is pulled out to eliminate the tape clogging.
- the carrier tape 900 having a short length that cannot be transported from the reels 810 and 820 is transported, the following measures are taken.
- the operator performs an operation similar to the above-described operation to open the tape transport path 38 between the second sprocket 62 and the third sprocket 63.
