As in the first to fourth embodiments, the bobbin 300c of the automatic winding apparatus according to the fifth embodiment of the present invention includes a cover 310c, a cylindrical portion, a flange portion, and a rotation center shaft. However, the cover 310c of the bobbin 300c of the fourth embodiment has a smooth cylindrical shape in which the outer periphery is not formed with a ratchet or a groove. The cover 310c of the bobbin 300c is formed of a magnetic material and the permanent magnet 440b is attached to the end of the stopper 414b of the stopper device 400b. Therefore, the friction between the permanent magnet 440b and the cover 310c of magnetic material is increased by the attractive force, and rotation of the bobbin 300c is restricted.

14 shows the structure of the stopper device 400b excluding the permanent magnet 440b using the same lever structure as that of the fourth embodiment and includes a lever 412b, a stopper 414b, a push key 416b, 420b, and a push spring 430b. However, as in the first embodiment, it is also possible to adopt a structure in which the push key is inserted in the stopper, and a permanent magnet is attached to the end of the stopper.

FIG. 15 is a view showing a rotation restricting structure of the automatic reel-up apparatus according to the sixth embodiment of the present invention.

In the automatic winding apparatus according to the sixth embodiment of the present invention, the remaining components except for the shape of the permanent magnet are the same as those of the fifth embodiment.

The contact surface of the permanent magnet 440d of the stopper device 400d included in the automatic winding apparatus according to the sixth embodiment of the present invention is in contact with the outer periphery 312c of the bobbin 300c cover 310c, And 312c, respectively.

Also in the sixth embodiment, as in the fifth embodiment, a structure in which a push key is inserted in the stopper in addition to the lever structure can be employed as the stopper device.

16 is a view showing a rotation restricting structure provided in the automatic rewinding apparatus according to the seventh embodiment of the present invention.

In the automatic rewinding apparatus according to the seventh embodiment of the present invention, the remaining components except for the cover shape of the bobbin are the same as those of the sixth embodiment.

The cover 310d of the bobbin 300d is formed of an injection molded body and the magnetic member 314d is coupled to the outer periphery 312d in a strip shape. The magnetic member 314d may be integrally formed with the bobbin 300d by insert injection or the like at the time of forming the bobbin 300d made of an injection material, and may be separately manufactured and then attached. And only a part of the outer circumference 312d which actually makes contact with the permanent magnet 440d is constituted by magnetic sintering, thereby reducing the overall weight and cost.

Like the fifth embodiment, the stopper device may have a structure in which a push key is inserted in the stopper in addition to the lever structure.
