In addition, since the end of the carrier tape is held in the locking hole near the center of the reel, it is possible to hold the end regardless of whether the surface is uneven such as an embossed carrier tape. it can. Moreover, since the locking hole penetrates the reel hub and the side plate, it is possible to easily visually check the mounting state of the carrier tape from the outside.

  Moreover, it is preferable that the reel for carrier tapes concerning this invention equips the arbitrary positions of the said slit with the holding member which has an elastic member urged | biased in the direction holding the inserted carrier tape.

  In the above configuration, since the holding member having the elastic member that urges the inserted carrier tape in the holding direction is provided at any position of the slit, the end of the held carrier tape does not easily fall off. In addition, by adjusting the biasing force of the elastic member, when the carrier tape is pulled with a certain tension or more, the wound carrier tape can be easily pulled out.

  In the carrier tape reel according to the present invention, a ball plunger is preferably used as the holding member.

  In the above configuration, since the ball plunger is used as the holding member, the end of the held carrier tape does not easily fall off, and the carrier tape can be pulled with a certain tension or more by adjusting the biasing force of the elastic member. When pulled, the wound carrier tape can be easily pulled out.

  According to the above configuration, since the slit capable of inserting the carrier tape is formed in the reel hub and the side plate, the carrier tape can be easily inserted by inserting the carrier tape between the two side plates and inserting the slit into the slit. It becomes possible to hold | maintain the edge part. Further, since the end portion of the carrier tape is held in the locking hole near the center of the reel, the end portion can be held regardless of whether the surface is an uneven surface such as an embossed carrier tape. . Moreover, since the locking hole penetrates the reel hub and the side plate, it is possible to easily visually check the mounting state of the carrier tape from the outside.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing the configuration of a carrier tape reel according to an embodiment of the present invention. The object to be wound up by the carrier tape reel according to the embodiment of the present invention is a paper tape used for transporting or storing microchips such as semiconductors and electronic parts, as well as a resin-made surface having irregularities. Including embossed carrier tape.

  As shown in FIG. 1, the reel (carrier tape reel) 1 for winding the carrier tape 20 winds the carrier tape 20 around the outer peripheral surface of a reel hub 11 having a cylindrical shape at the center. In order to constrain the position of the wound carrier tape 20 in the rotation axis direction of the reel 1 so that the wound carrier tape 20 does not protrude from the reel 1, both side surfaces of the reel hub 11 facing each other in the rotation axis direction A side plate 12 is provided.

  The reel hub 11 is provided with a locking hole 15 for locking the carrier tape 20. The locking hole 15 penetrates the side plate 12 in the rotation axis direction of the reel hub 11. In addition, the reel hub 11 and the side plate 12 are formed with slits 13 through which the carrier tape 20 can be inserted so as to communicate the locking holes 15 with the outer peripheral surface of the reel hub 11.

  The slit 13 is preferably formed from the outer peripheral surface of the reel hub 11 toward the locking hole 15 in the direction in which the carrier tape 20 is inserted. This is because the inserted carrier tape 20 can be easily inserted into the slit 13. The carrier tape 20 inserted through the slit 13 is guided to the locking hole 15, and when the end reaches the locking hole 15, the reel 1 is rotated so that the end of the carrier tape 20 is moved to the locking hole 15. The carrier tape 20 can be wound up.

  Since the locking hole 15 penetrates the reel hub 11 and the side plate 12, the mounting state of the carrier tape 20 can be visually confirmed from the outside. That is, it can be seen at a glance whether or not the end of the carrier tape 20 has reached the locking hole 15, and it can be easily confirmed whether or not the carrier tape 20 has come off.

  FIG. 2 is a front view showing a state when the carrier tape 20 of the carrier tape reel 1 according to the embodiment of the present invention is attached. As shown in FIG. 2, the carrier tape 20 is inserted between the two side plates 12 from the outer peripheral side of the reel 1 in a direction in contact with the outer peripheral surface of the reel hub 11.

  Next, the carrier tape 20 is inserted into the slit 13 formed in the reel hub 11 and is inserted until the end of the carrier tape 20 reaches the locking hole 15. In the present embodiment, a guide hole 21 is provided in the side plate 12, and the inserted carrier tape 20 is taken out from the guide hole 21 to the outer peripheral side of the side plate 12 and is inserted through the slit 13. Thereby, the inserted carrier tape 20 can be easily inserted into the slit 13.

  As described above, since the slit 13 through which the carrier tape 20 can be inserted is formed in the reel hub 11 and the side plate 12, the carrier tape 20 inserted between the two side plates 12 is inserted into the slit 13. As a result, the end of the carrier tape 20 can be easily held. Further, since the end portion of the carrier tape 20 is held by the locking hole 15 near the center portion of the reel 1, the end portion can be used regardless of whether the surface is uneven or not like an embossed carrier tape. Can be held. Further, since the locking hole 15 penetrates the reel hub 11 and the one side plate 12, the mounting state of the carrier tape 20 can be easily visually confirmed from the outside.

  In addition, the elasticity which biases the carrier tape 20 to the direction which presses the wall surface of the slit 13, ie, the direction which hold | maintains the carrier tape 20, so that the carrier tape 20 inserted in the slit 13 may be hold | maintained in the arbitrary positions of the slit 13. It is preferable to provide the holding member 14 which has a member. Since the carrier tape 20 inserted into the slit 13 can be held by the holding member 14, the end portion of the held carrier tape 20 does not easily fall off. Further, by adjusting the elastic force of the elastic member, when the carrier tape 20 is pulled with a certain tension or more, the wound carrier tape 20 can be easily pulled out.

  In the present embodiment, a ball plunger is used as the holding member 14. FIG. 3 is a schematic diagram showing the configuration of the ball plunger (holding member) 14 of the carrier tape reel 1 according to the embodiment of the present invention.

(Elastic member) 142, and a frame portion 143 that holds a ball portion 141 and a spring (elastic member) 142. More preferably, the ball portion 141 of the ball plunger 14 is held by the frame portion 143 so as to be rotatable. In addition, by setting the radius of the ball portion 141 to be equal to or larger than the width of the slit 13, the carrier tape 20 is not erroneously guided to the lower portion of the ball portion 141 and can be smoothly inserted. In addition, since the ball portion 141 is spherical, when the carrier tape 20 is pulled with a certain tension or more, the wound carrier tape 20 can be easily pulled out. Further, the frame portion 143 may be configured as a part of the reel 1. Further, the member biased toward the slit 13 does not necessarily have a spherical shape, and may be an elliptical cylindrical shape, a cylindrical shape, or the like.

  The holding member 14 is not limited to a ball plunger. For example, the holding member 14 may be configured to include an annular ring at the tip of a spring, and the carrier tape 20 can be easily inserted, and the carrier tape 20 is pulled with a certain tension or more. In such a case, any configuration can be used as long as it can be easily extracted.

  As described above, in the carrier tape reel 1 according to the embodiment of the present invention, the slit 13 through which the carrier tape 20 can be inserted is formed in the reel hub 11 and the side plate 12, so that two side plates are formed. By inserting the carrier tape 20 between 12 and inserting the carrier tape 20 through the slit 13, the end of the carrier tape 20 can be easily held. Further, since the end portion of the carrier tape 20 is held in the locking hole 15 in the vicinity of the center portion of the carrier tape reel 1, the end portion is formed regardless of whether the surface is uneven or not like an embossed carrier tape. Can be held. Further, since the locking hole 15 penetrates the reel hub 11 and the one side plate 12, the mounting state of the carrier tape 20 can be easily visually confirmed from the outside.

  In addition, it goes without saying that the embodiment described above can be changed without departing from the spirit of the present invention.
