Abstract

A tape is prevented from moving in a width direction and the tape is prevented from being damaged in a state in which the tape is wound around a tape reel. There is provided a tape reel including: a cylindrical portion around which a tape is wound; a first flange annularly projecting toward an outer side in a radial direction of the cylindrical portion from the cylindrical portion; and a second flange separated from the first flange in an axial direction of the cylindrical portion and annularly projecting toward the outer side in the radial direction from the cylindrical portion, in which a distance between the first flange and the second flange becomes narrower while extending toward the outer side in the radial direction, and a bending elastic modulus of the first flange is smaller than a bending elastic modulus of the second flange.

First claim

What is claimed is:

1. A tape reel comprising:
a cylindrical portion around which a tape is wound;
a first flange annularly projecting toward an outer side in a radial direction of the cylindrical portion from the cylindrical portion; and
a second flange separated from the first flange in an axial direction of the cylindrical portion and annularly projecting toward the outer side in the radial direction from the cylindrical portion,
wherein a distance between the first flange and the second flange becomes narrower while extending toward the outer side in the radial direction in a state before the tape is wound around the cylindrical portion, and
a bending elastic modulus of the first flange is smaller than a bending elastic modulus of the second flange.

2. The tape reel according to claim 1 ,
wherein the distance between an edge part at the outer side in the radial direction of the first flange and an edge part at the outer side in the radial direction of the second flange is narrower than a width of the tape.

3. The tape reel according to claim 1 ,
wherein the bending elastic modulus of the first flange is smaller than a bending elastic modulus of the tape.

4. The tape reel according to claim 1 ,
wherein the bending elastic modulus of the second flange is smaller than a bending elastic modulus of the tape.

5. The tape reel according to claim 1 ,
wherein the second flange is formed integrally with the cylindrical portion.

6. The tape reel according to claim 1 ,
wherein the first flange is a separate body from the cylindrical portion.

7. The tape reel according to claim 6 ,
wherein the first flange is inclined with respect to an orthogonal direction to the axial direction when viewed in the radial direction, and
the second flange projects along the orthogonal direction when viewed in the radial direction.

8. A tape cartridge comprising:
the tape reel according to claim 1 ; and
a case that rotatably supports the tape reel and accommodates the tape reel and the tape wound on the tape reel.
