Embodiments of the present invention will be described below with reference to the drawings. The description will be made specifically using an embodiment. First Embodiment FIG. 1 is a front view showing a configuration of a reel for electronic component storage according to a first embodiment of the present invention when folded, FIG. 2 is a left side view showing the reel for electronic component storage, and FIG. FIG. 3 is a sectional view taken along line AA of FIG. 2. 4 is a front view showing a configuration of the electronic component storage reel when it is deployed, FIG. 5 is a left side view showing the electronic component storage reel, and FIG. 6 is a cross-sectional view taken along line BB of FIG. It is. The electronic component storage reel 1 of this example is shown in FIGS.
As shown in FIG. 6, rectangular first flanges 3A, 3B and second flanges 4A, 4B each having an opening 7 at the center thereof are attached to both left and right ends of the cylindrical hub 2 so as to overlap each other. The first flanges 3A, 3B attached to the outside of both ends of the hub 2 are fixed to the side surface of the hub 2 with an adhesive, while the second flanges 3A, 3B attached to the inside of both ends of the hub 2 are attached. The flanges 4A and 4B are rotatably attached to the hub 2. 2nd flange 3A,
The rotation of 3B is configured such that left and right can be independently performed. Hub 2, first flange 3A, 3B
For the material of the second flanges 4A and 4B, a conductive material such as a conductive plastic is used.

The hub 2, the first flanges 3A and 3B and the second
A guide hole 5 is formed to penetrate the flanges 4A and 4B. The guide hole 5 and the opening 7 are provided to facilitate handling by inserting a rotation preventing bar (not shown) when the TCP storage reel 1 is handled. Steps 8A and 8B having a small diameter are formed on the circumferential surfaces at both ends of the hub 2, and second flanges 4A and 4B are rotatably attached to the steps 8A and 8B, respectively. The attachment of the second flanges 4A, 4B to the hub 2 is performed prior to the attachment of the first flanges 3A, 3B. That is, first, the second flanges 4A, 4B are attached to the steps 8A, 8B of the hub 2, respectively, and then the first flanges 3A, 3B are attached to the side surfaces of the hub 2 via an adhesive. When attaching the first flanges 3A, 3B and the second flanges 4A, 4B, it is desirable to attach them so that an appropriate tension acts between the two flanges 3A, 3B and 4A, 4B. This is to prevent the second flanges 4A and 4B, which are rotatably mounted, from easily rotating except when necessary. Then, a TCP tape is wound around the circumferential surface 2A of the cylindrical hub 2 and stored.

Next, a method of using the electronic component storage reel 1 of this embodiment will be described. First, when the TCP tape is not stored, as shown in FIGS. 1 to 3, the second flanges 4 </ b> A and 4 </ b> B are rotated with respect to the hub 2 to rotate the first flange 3.
By overlapping with A and 3B, the empty electronic component storage reel 1 is folded. Thus, when the user returns the electronic component storage reel 1 to the sender, as shown in FIG. 16B, the folded electronic component storage reel 1 is placed in the return container in the X (horizontal) direction and the Y direction. By storing in the (longitudinal) direction and further in the height direction, even in the case of returning a large amount, it is possible to return without occupying an extra volume. Therefore, the volume occupied by the electronic component storage reel 1 can be reduced except when the TCP tape is stored, so that the transport efficiency at the time of return can be improved. On the other hand, in the conventional example, as shown in FIG. 16A, the storage reel 51 cannot be folded, so that the structure shown in FIGS. 17 to 19 is maintained even when the TCP tape is not stored. Therefore, when returning a large amount, the occupied volume becomes considerably large.

Next, when storing the TCP tape,
As shown in FIGS. 4 to 6, the second flanges 4A and 4B are
From the position shown in FIGS. 1 to 3, the hub 2 is manually expanded (rotated) clockwise or counterclockwise with respect to the hub 2 so as to cross the first flanges 3A and 3B. In order to make the explanation easy to understand, as is clear from FIG.
In this example, the flanges 4A and 4B are rotated by the same angle of approximately 90 degrees along the circumferential surfaces of the steps 8A and 8B of the hub 2 with respect to the first flanges 3A and 3B. Thus, the first

Since A, 3B and 4A, 4B function as guides, the storing operation can be smoothly performed as described later.

Next, as shown in FIG. 7, the tape is wound along the circumferential surface 2A of the hub 2 of the electronic component storage reel 1 using a TCP tape 10 holding an electronic component 20 such as an LSI in advance. Turn. Electronic components 2 between each TCP tape 10
A spacer tape 9 is interposed between the spacer tapes 9 to protect them. As is clear from the figure, the first flanges 3A, 3B
In addition, since the second flanges 4A and 4B function as guides at both ends of the hub 2, the operation of winding the TCP tape 10 around the circumferential surface 2A of the hub 2 is performed smoothly. FIG. 8 is a left side view showing another developed example of the electronic component storage reel 1 of this example, and FIG. 9 is a cross-sectional view taken along the line CC of FIG. When actually handling the electronic component storage reel 1,
Operability is improved when the second flanges 4A and 4B are independently rotated than when they are integrally rotated. That is, as shown in FIGS. 8 and 9, even when the left and right second flanges 4A and 4B are independently rotated by an arbitrary angle, the second flanges 4A and 4B are developed in the same manner as in FIGS. Therefore, the work can be smoothly performed when the TCP tape 10 is wound.

As described above, according to the configuration of this embodiment, the first and second rectangular flanges 3A and 3B having the opening 7 at the center are provided at the left and right ends of the hub 2, respectively.
A and 4B are attached so as to overlap with each other, and the first flanges 3A and 3B attached outside the both ends of the hub 2 are fixed to the side surfaces of the hub 2 and attached inside the both ends of the hub 2. Since the second flanges 4A and 4B are rotatably attached to the hub 2, the
Since the flanges 3A, 3B and 4A, 4B can be folded up except when the tape 10 is stored, the volume occupied by the electronic component storage reel 1 can be reduced. Therefore, the transport efficiency at the time of return can be improved without separating the hub and the flange.
