Tape reel

Abstract

A tape reel is disclosed, which includes a first reel disk and a second reel disk. The first reel disk includes plural first coupling structures. The second reel disk has plural third coupling structures. The third coupling structures would couple to the first coupling structures for positioning by rotating the first reel disk and the second reel disk. The first reel disk may include plural second coupling structures staggered to the first coupling structures. There is a height difference between the first and second coupling structure. The third coupling structures would selectively couple to the first coupling structures or the second coupling structures. A first gap is formed between the first and second reel disk when the third coupling structures couple to the first coupling structures. A second gap is formed between the first and second reel disk when the third coupling structures couple to the second coupling structures.
