欠点があった。However, when the remaining amount of the striated body becomes small, light may pass through the gap between the striated bodies and cause a malfunction. This malfunction is even more frequent in the case of a striated body whose outer coating is transparent, for example, an optical fiber core or a taped core obtained by tape-forming the same, so that a considerable amount of wire is used. A bobbin replacement process was performed with the strip remaining on the bobbin, resulting in a disadvantage that the strip was extremely wasteful.

In the case of the present invention, a special guide device is used when the striated body 3 is first extended from the bobbin 1. That is, the bobbin 1 is fed through a contact point P of a pair of guide rollers 4 which passes through a center point M between both flanges of the rotation axis of the bobbin 1 and is in contact with a plane perpendicular to this axis and in contact with each other.
【0006】もう一つの繰り出しの条件としてはボビン

ものとする。[0006] Another condition of the feeding is that the traverse width is wound smaller on the body of the bobbin 1 such that the striated body 3 goes up to the upper winding layer so as to form a trapezoid ABCD. .

Note that this is the feeding path that the striated body 3 takes when the striated body 3 of the bobbin 1 is empty. In the present invention, a light projecting element and a light receiving element (not shown in FIG. 1) are provided to arrange the light projecting / receiving straight line 5 so as to intersect these straight lines AP and BP.

ついてでもよいのであるが、確実性を増すために両方に
設置する。It is desirable that the intersection of the light projecting / receiving straight line 5 and the straight lines AP and BP be orthogonal. Therefore, the light emitting and receiving elements which do not appear in FIG. 1 take positions on a straight line perpendicular to the plane of FIG. The installation may be performed on either one of the straight line of the AP and the BP. However, the installation is performed on both of them to increase reliability.

ーが急激に減少するなどの変化が見られることになる。The actual state of feeding when the apparatus of the present invention is used is as follows. That is, immediately after the start of use of the bobbin 1, the feeding start point Q gradually moves to the winding layer closer to the trunk portion while traversing along the upper side CD of the trapezoid as exemplified by QP. And bobbin 1
Is empty, the payout line QP coincides with the AP, so that it intersects with the light projecting / receiving straight line 5, and changes such as a sudden decrease in received light energy are observed.

はないからこの心配も皆無となる。[0010] In addition, there is a concern that when the wire 3 is unreeled from the bobbin 1, wire run-out may occur, which may cause malfunction. However, in the case of a trapezoidal winding, the wire run-out does not go outward. No worries.

できる利点がある。According to the present invention, the bobbin empty signal is emitted after the striatum wound on the bobbin completely disappears or the error becomes very small even if there is an error. The amount of the remaining striatum is extremely small, and there is an advantage that the waste dose to be rejected can be reduced and waste can be omitted.
