Claims
- 1. A tape reel comprising:
- an upper flange;
- a hub between said flanges;
- a lower flange;
- thin flange portions which result from uniformly reducing relative to an outer peripheral edge portion a thickness in front and rear flange surfaces of said upper and lower flanges, respectively, in a molding process; and
- a plurality of tape position restricting ribs formed on said upper and lower flanges only at tape contact flange surfaces of said thin flange portions such that said plurality of tape position restricting ribs are radially extended from a central portion of said tape reel to said outer peripheral edge portions.
- 2. The tape reel according to claim 1, wherein each said outer peripheral edge portion has a predetermined width.
- 3. The tape reel according to claim 2, wherein outermost surfaces of said plurality of tape position restricting ribs are on the same plane with the corresponding surfaces of said outer peripheral edge portions.
- 4. The tape reel according to claim 2, further comprising:
- thick portions which are thicker than said thin flange portions being formed at a plurality of places in the vicinity of said outer peripheral edge portions.
- 5. The tape reel according to claim 4, wherein said thick portions are formed on flange surfaces opposite said tape contact flange surfaces.
- 6. The tape reel according to claim 4, wherein three tape position restricting ribs are formed equally spaced along each outer peripheral edge portion.
- 7. The tape reel according to claim 6, wherein said tape position restricting ribs divide the corresponding flange surfaces into three equal portions and said thick portions are located at midpoints along the outer peripheral edge portion of each of said three equal portions.
