6c and 37c are located on the cylindrical surface, and the outer ends 36c and 37c of the connecting protrusions 36a, 36b, 37a, and 37b.
The tape member can be tightly wound around and the connecting convex pieces 36a, 36b, 37a, 37b can function as a winding core. In addition, the connecting convex pieces 36a, 36b,
Since the holding convex piece 38 is provided on the same circle as 37a, 37b, these connecting convex pieces 36a, 36b, 3
The core function of 7a and 37b can be made more reliable by the holding projection 38.

When the connecting projections 36a and 36b are erected, they are radially arranged in the radial direction of the flange plates 32 and 33, and the connecting projections 37a and 37bc are erected in the circumferential direction of the flange plates 32 and 33. As a result, a space is formed between the adjacent connecting convex pieces 36a, 36b, 37a, 37b, and when the tape member is wound, the tip of the tape member is inserted into this space. It is possible to engage between the adjacent connecting convex pieces 36a, 36b, 37a, 37b. Further, when the connecting projections 37a, 37b are erected, they are arranged in the circumferential direction of the flange plates 32, 33, so that the tape member can be guided along the connecting projections 37a, 37b, and the tape member can be smoothly moved. And it can be wound neatly.

Since it is adhered to the flange plates 32 and 33, it is not necessary to separately prepare another connecting member to connect the flange plates 32 and 33 to each other, so that the yield and assemblability of the paper of the material are improved, and the cost is reduced. It can be reduced. Further, since the flange plates 32 and 33 are made of paper, the tape member wound around the reel 30 can be used up, and when the reel 30 is discarded, it can be discarded together with other combustible waste. Disposal becomes very easy.

The holding portion 35 includes the flange plates 32 and 33.
The holding convex piece 38 formed by cutting and raising the holding convex piece 38 and the groove portion 39 into which the tip end of the holding convex piece 38 is locked are formed by cutting and raising the holding convex piece 38 integrally with the flange plates 32 and 33.
Flange plates 32, 33 are prepared by separately preparing another holding member.
Since it is not necessary to connect them to each other, the yield and the assemblability of the material paper can be improved, and the cost can be reduced. Furthermore, by a simple operation such as engaging the tip end portion of the holding convex piece 38 with the groove portion 39, the holding convex piece 38 can be erected and the flange plate 32, 33 can be reliably held at a predetermined distance. . Further, since the holding convex piece 38 is cut and raised in the radial direction, the holding convex piece 38 is arranged along the circumferential direction when it is erected, and when the tape member is wound, the tape member is wound. Can be wound along the holding convex piece 38, and the tape member can be smoothly and neatly wound.

In the present embodiment, the connecting convex pieces 36a formed by cutting and raising the flange plate 32 in the circumferential direction are adhered to the opposing flange plate 33, and the flange plate 33 is circumferentially formed (the flange plate 33 from the outer side). Flange plate 32 when seen

Are bonded to the opposing flange plates 32, and the flanges 32 are cut and raised in the radial direction to form connecting projections 3
7a is adhered to the opposing flange plate 33 to form the flange plate 3
Connecting protrusion 37b formed by cutting and raising 3 in the radial direction
Are bonded to the opposing flange plate 32, and the connecting convex piece formed by cutting and raising one of the flange plates and the cut-and-raising direction of the one connecting convex piece when the other flange plate is viewed from the outside. Alternatively, the connecting convex pieces formed by cutting and raising in the same direction may be bonded to each other. In this case, one connecting convex piece and the other connecting convex piece are adhered to increase the paper thickness, and when the tape member is wound around these connecting convex pieces, the connecting convex pieces buckle and bend. This can be avoided, and the tape member can be wound neatly and reliably.

Further, in this embodiment, the connecting portion 35 is constituted by connecting convex pieces 36a, 36b cut and raised in the circumferential direction and connecting convex pieces 37a, 37b cut and raised in the radial direction. It may be configured only by the connecting convex pieces cut in the circumferential direction, or may be configured only by the connecting convex pieces cut in the radial direction.

When the reel 30 is wound around a series of electronic parts, the tape member and the flange plates 32, 3 are formed.
Although there is a risk that paper dust will be generated due to friction with 3 and the like, and the reliability of electronic devices manufactured by this paper dust may be reduced, the flange plate 3 is required to suppress the generation of paper dust.
A resin may be coated on the surfaces of Nos. 2, 33 and the recessed surface of the cut and raised portion. Alternatively, a high-quality paper material that does not easily generate paper dust even if rubbed may be used.

Further, although the reel 30 uses the flat flange plates 32 and 33, there is a possibility that they may warp in the direction in which they approach each other.
By using a corrugated product that extends in the circumferential direction or the radial direction for the second and the third parts, this warp can be significantly suppressed, and the tape member can be reliably wound. Further, instead of the corrugating process, slits extending in the circumferential direction, the radial direction, or spirally extending may be formed in the flange plates 32 and 33.
