[Prior Art]

 The film carrier can be used for miniaturization and thinning of various electronic devices, and is therefore widely used as a circuit board on which so-called electronic components are mounted. In addition, since this film carrier can be formed by continuous and short-time processing by a so-called reel-to-reel method for a long insulating base material such as an epoxy glass tape, various forms are available. Have been developed and used.

Various processings by the reel-to-reel method such as plating and etching for such a long insulating base material are performed by a processing apparatus as shown in FIG. 7. In this case, The long insulating base material is transported in the processing device by winding it around one reel. For that purpose, the end of the long insulating base material has to be fixed to the reel before processing, but the conventional fixing method is as shown in FIG. For example, the tape is temporarily fixed with an adhesive tape or the like, and a part of the long insulating base material is further wound and fixed on the temporary fixing.

By the way, in such a long insulating base material, as shown in FIG. 6, sprocket holes for stable transportation are formed on both sides of the long insulating base material. It is formed assuming that the insulating base material is loaded in the correct position on the reel, and if the end of the long insulating base material is not loaded in the correct position on the reel, The long insulating base material was wound and transported while meandering, and in some cases, the long insulating base material came off the sprocket. Also, when trying to fix the end of the long insulating base material at the correct position with respect to the inner surface of the reel, it is necessary to put hands between the side plates that make up the reel. The work took a lot of time.

Therefore, the inventors of the present invention have conducted various studies as to how to make the initial winding fixation for a reel of this type of long insulating base material simple and accurate. The present invention has been completed.

[0006]

[Problems to be solved]

 The present invention has been made on the basis of the above circumstances, and a problem to be solved by the invention is to make the fixing of the end portion of the long insulating base material to the reel easy and accurate.

An object of the present invention is to provide a reel that can easily load the end portion of the long insulating base material even at the correct position with a simple structure.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the means adopted by the present invention will be described with reference to the reference numerals used in the examples. "Plating or the like on the long insulating base material 10 conveyed by winding. In the reel 20 used in manufacturing the film carrier for mounting the electronic component by performing various processes described above, the end of the long insulating base material 10 is pressed against the winding inner surface 21 of the reel. And a support pin 23 for positioning and fixing the end portion of the long insulating base material 10 in the sprocket hole 11 formed in the inner surface of the lid body 22 or a part of the winding inner surface 21. The reel 20 for a long insulating base material characterized in that it is provided.

[0009]

[Function of the device]

 The operation of the reel 20 according to the present invention constructed as above will be described below together with the mode of use thereof.

First, the end of the long insulating base material 10 has to be positioned with respect to the reel 20, and this is done integrally with the winding inner surface 21 side of the reel 20 or the back surface side of the lid 22. It is a pair of support pins 23 formed. That is, these support pins 23 are to be inserted into the sprocket holes 11 formed on both sides of the long insulating base material 10, and are paired on both sides of the end portion of the long insulating base material 10. By inserting the support pins 23 into the sprocket holes 11 of the above, the accurate positioning of the long insulating base material 10 with respect to the reel 20 is automatically performed. In this case, since the sprocket holes 11 are formed on both sides of the long insulating base material 10 at regular intervals, the pair of sprocket holes 11 into which the pair of support pins 23 are inserted are formed. If the long insulating base material 10 is not the right and left and is displaced, the long insulating base material 10 will be largely shaken with respect to the reel 20. It is naturally determined by the normal human senses. In other words, if the long insulating base material 10 is extended with respect to the reel 20 in the usual manner, the correct insertion of each support pin 23 into the sprocket hole 11 is automatically performed.

Next, the end of the long insulating base material 10 must be fixed to the reel 20, and the lid 22 is used for this purpose. In the lid body 22 of the first embodiment shown below, it is simply rotated to the winding inner surface 21 side of the reel 20, and in the lid body 22 of the second embodiment, it is inserted into each sprocket hole 11. The fixing of the long insulating base material 10 to the reel 20 is completed only by inserting the supporting pin 23 into the fixing hole 25 on the reel 20 side.

In addition, the reel 20 is provided with a pair of support pins 23 protruding from the winding inner surface 21 of the reel 20 for fitting into the sprocket holes 11 of the long insulating base material 10. In any of the embodiments, the support pin 23 is covered with the lid 22 whose front side is curved to match the curved surface of the winding inner surface 21, so that the wound long insulating base material 10 and the support pin 23 It goes without saying that the long insulating base material 10 is not damaged because it does not come into direct contact with 23.

As described above, in the process of sequentially winding the positioned and fixed long insulating base material 10 on the reel 20, the long insulating base material 10 is accurately positioned with respect to the sprocket hole 11. Since it is loaded, the long insulating base material 10 does not meander or come off from the sprocket (not shown).
