BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding tape of an embossed carrier tape, and in particular, a recessed portion on the lower surface of an embossed carrier tape (which may or may not contain electronic parts in each pocket) on the winding surface of a reel hub. The present invention relates to a take-up reel provided with a locking piece that engages with.

2. Description of the Related Art As a take-up reel of this kind, Japanese Patent Laid-Open No.
─16468. According to this publication, the take-up reel is provided with a locking piece on the take-up surface of the reel hub, which engages with a recess on the lower surface of an embossed carrier tape (a tape containing electronic components in a pocket). Then, when winding, the lower surface concave portion of the winding start end is hooked on the locking piece and wound up, and when rewinding, the final end of the embossed carrier tape is naturally separated from the locking piece. Compared with the case where the winding start end of the conventional embossed carrier tape is fixed to the hub with a drafting tape or inserted into a groove provided in the hub, it is disclosed in Japanese Patent Laid-Open No. 4-1646.
The take-up reel of No. 8 is characterized in that the final end of the embossed carrier tape comes off from the reel hub without resistance when rewinding.

[0003]

However, in the above-mentioned take-up reel, when the recessed portion on the lower surface of the embossed carrier tape is hooked on the locking piece, the winding start end of the tape does not come off the reel hub. Therefore, it is necessary to wrap the embossed carrier tape for at least one turn. This preparation for winding is considerably easier than the case of simply winding without providing a locking piece, but still there is a problem that it is very troublesome because it is necessary to wind one round using the window of the flange. Therefore, an object of the present invention is to wind the embossed carrier tape so that the winding start end of the embossed carrier tape can be stopped on the reel hub with one touch, and the end portion of the tape can be removed from the reel hub without any resistance when rewound. To provide a take-up reel.

[0004]

SUMMARY OF THE INVENTION In the take-up reel for an embossed carrier tape, the reel hub has a take-up surface provided with a locking piece for engaging with a recess on the lower surface of the embossed carrier tape. The problem can be solved by providing a step higher than the height of the embossed carrier tape at a position in front of the locking piece and providing a pressing portion for pressing the winding start end of the embossed carrier tape at the step. The take-up reel according to the present invention can be used as either an embossed carrier tape having electronic parts or the like stored in a pocket or an unembossed carrier tape. The pressing portion may be provided separately from the eaves at the upper part of the step, or the wall of the step may be removed and the back side of the winding surface of the reel hub may be utilized. If the step with the pressing part is too close to the locking piece, when the bottom surface recess of the embossed carrier tape comes off from the locking piece during the final rewinding, it interferes with the pressing part and moves back, and the bottom surface recessed part of the last part engages. Since it may be difficult to come out of the stopper, it is desirable that the step having the pressing portion be provided so as not to interfere with the engaging piece.

[0005]

According to the present invention, when the embossed carrier tape is wound, the winding start end of the tape is inserted into the pressing portion and then slightly pulled so that the lower surface recess of the embossed carrier tape is aligned with the locking piece position of the reel hub. Winding preparation can be done with one touch. Also, at the time of rewinding, the bottom surface recess of the embossed carrier tape is disengaged from the locking piece when the locking piece passes through the downward step in the final winding, and the reaction force in the circumferential direction supporting the locking piece disappears. The end naturally comes out of the pressing part and comes off the reel hub without any resistance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed description will be given below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which the outer peripheral portion of a winding reel 10 for winding the embossed carrier tape 1 is omitted,
It is the figure which expanded and showed the reel hub 11 which is a principal part. On the winding surface 12 of the reel hub 11, a locking piece 13 that engages with the lower surface recess 2 of the embossed carrier tape 1 is provided. In the figure, pockets 3 and 3 for storing electronic parts
Although the groove between the two is used as the lower surface recessed portion 2 of the embossed carrier tape 1, a dedicated recessed portion may be provided at a certain distance from the winding start end of the embossed carrier tape separately. The locking piece 13 that engages with the concave portion 2 has a height lower than the pocket depth and a width between the pockets 3 and 3 in order to prevent the pocket 3 from being deformed and to be easily detached at the time of rewinding. It is desirable to make it narrower than the groove. The length of the locking piece 13 may be the same as or shorter than the length of the reel hub 11.

A step 14 is provided on the winding surface 12 of the reel hub 11 at a position before the locking piece 13. The step 14 of the winding surface 12 is higher than the height of the embossed carrier tape 1, and the winding start end 4 of the embossed carrier tape 1 is used to make the winding surface 12 of the reel hub 11 use the height.
A pressing portion 15 is provided so as not to be lifted from above. The pressing portion 15 of this embodiment is provided by extending the winding surface 12 of the reel hub 11 above the step 14 or by retreating the wall forming the step 14 on the contrary, and winding up the embossed carrier tape 1. At this time, the winding start end 4 of the embossed carrier tape 1 has the step 14 at the winding surface 1
It is inserted in the gap 16 between the two 2 and 12. Therefore, if the height of the step 14 is too low, the height of the gap 16 into which the winding start end 4 is inserted may not be sufficient, and there is a risk of hindrance during winding or rewinding. It is necessary to make the height of the step 14 sufficiently high so that a margin that does not feel resistance can be secured. In addition, the height of the gap 16 is increased as it goes deeper so that the winding start end 4 can be moved to some extent in the radial direction of the reel hub 11, that is, the lower winding surface 12 is moved closer to the center of the reel hub. It is even better to make the shape so as to reduce the resistance at the time of returning. If the step 14 having the pressing portion 15 is too close to the locking piece 13, it may interfere with the locking piece 13 at the time of rewinding and the embossed carrier tape 1 may become difficult to come off. It is better to install it. In the figure, 17 is a flange of the take-up reel 10,
Reference numeral 18 is a window provided on the flange 17.

Now that the structure has been described, a method of preparing for winding will be described. First, the length from the lower surface concave portion 2 of the embossed carrier tape 1 to the winding start end 4 is slightly shorter than the arc length of the pressing piece 15 position provided on the step 14 of the reel hub 11 and then the winding. In the illustrated case, the reel 10 is rotated counterclockwise to bring the winding start end 4 of the embossed carrier tape 1 between the winding surfaces 12, 12 at the step 14 position when the step 14 and the locking piece 13 come to the upper side. The lower surface recessed portion 2 of the embossed carrier tape 1 is hooked on the locking piece 13 while being inserted into the gap 16 and slightly pulling out the embossed carrier tape 1. In the case of the present invention, the outward movement of the winding start end 4 of the embossed carrier tape 1 in the radial direction of the hub is limited by the pressing portion 15, and the movement in the circumferential direction is limited by the locking piece 13. Even embossed carrier tape 1
Is naturally wound on the take-up reel 10. Next, it will be explained how the final winding portion is removed without resistance when rewinding. From FIG. 1, when the take-up reel 10 further rotates clockwise and the embossed carrier tape 1 rotates further below the position where the embossed carrier tape 1 separates from the winding surface 12,
The lower surface recess 2 of the embossed carrier tape 1 is disengaged from the locking piece 13. In this state, since the embossed carrier tape 1 is free to move in the circumferential direction, it is removed from the gap 16 provided in the step 14 by the weight of the embossed carrier tape itself. In this embodiment, since the gap 16 of the step 14 is closed by the wall, dust cannot enter the inside of the hub.

FIG. 2 is an enlarged view of only the reel hub 11 which is the main part of another embodiment. In the drawings, the same reference numerals indicate the same names, so the description thereof will be omitted and only different parts will be described. In this embodiment, unlike the previous embodiment, there is no wall of the step 14 and the back side of the upper winding surface 12 is used as the pressing portion 15. Further, the lower winding surface 12 that overlaps the upper side has a gap 1 between the upper and lower winding surfaces 12, 12.
The height of 6 is inclined toward the center of the hub. Other configurations and the method for preparing the winding of the embossed carrier tape 1 are the same as those in the above-mentioned embodiment,
The difference from the above embodiment is that the length from the winding start end 4 of the embossed carrier tape 1 to the lower surface concave portion 2 is larger than the length of the arc between the step 14 and the locking piece 13, which is a limitation compared to the above embodiment. Is that there are few.

[0010]

As described above, according to the present invention, the winding start end of the embossed carrier tape can be stopped on the reel hub with one touch, and at the time of rewinding, the last portion of the tape is removed from the reel hub without any resistance. be able to.
