-Prior Art- In order to reduce light leakage loss at the connection portion of an optical fiber as much as possible, a technique is known in which the end portion of the optical fiber is polished into a convex spherical surface and butt-connected. A ferrule is provided at the connecting end of the optical fiber to protect the fiber and serve as a connecting member. Spherical polishing of the connecting end of the optical fiber is achieved by polishing the tip of this ferrule into a spherical shape. . A conventional polishing device for polishing the tip of a ferrule into a spherical surface has a holder that grips the ferrule and a polishing dish facing the holder and having a concave spherical polishing surface. By rotating and relatively swinging around the center point of the concave spherical surface, the tip of the ferrule is polished into a convex spherical shape.

On the other hand, polishing work requires a polishing liquid and abrasive powder, and the polishing surface of the polishing plate is also worn out by performing the polishing work. Since the worn polished surface reduces the processing accuracy and work efficiency of the ferrule tip, it must be shaped by dressing. However, since this dressing operation requires high precision and is complicated, it is difficult to carry out at the site where the fiber is laid, which often causes obstacles to the polishing operation at the site where the fiber is laid. Further, polishing work performed using polishing liquid or abrasive powder is complicated at the installation site, and a polishing device that can perform the work more easily is required.

On the other hand, a disposable polishing sheet is known as a polishing tool that does not require dressing work and does not require polishing liquid or abrasive powder. However, this polishing sheet is flexible but not stretchable, and therefore cannot form a spherical polishing surface. Therefore, with the prior art, it has been impossible to polish the spherical surface of the ferrule tip using a polishing sheet.

Polishing surface plate 30 provided with a cylindrical polishing surface 37 by pasting a polishing sheet 36 on the sheet pasting surface
In FIGS. 1 and 2, which are shown with the rotary table 3 mounted, by rotating the electric motor 5,
rotates within the housing 1, and therefore the X defined in Fig. 1
It also rotates in the axial direction and Y-axis direction. now rotary table 3
Considering a rotating coordinate system fixed at
0 rotates, the planetary gear 11 also rotates. With this rotation, the first drive pin 9 and the second drive pin 13 are connected to the center axis of the rotary table 3 and the planetary gear 1.
The first drive pin 9 reciprocates the polishing surface plate 30a in the X-axis direction on the slide table 15, and the second drive pin 13 rotates the slide table 15 on the rotary table 3 in the Y-axis direction. drive back and forth in the direction.

The slide base 15 is driven in the Y-axis direction by the drive pin 13 to reciprocate linearly in the direction of its cylindrical center axis, and the first drive pin 9 causes it to reciprocate around its cylindrical center axis. Therefore, the ferrule 40 is pressed against the polishing surface 37 in a fixed position.
The tip is rubbed on the polishing surface 37 while drawing a resurge locus determined by the gear ratio of the sun gear 10 and the planetary gear 11, and this gear ratio is slightly shifted from a simple integer ratio. If it is set as , the above-mentioned locus will be drawn on substantially the entire surface of the polishing surface 37, and polishing can be performed using substantially the entire surface of the polishing surface 37. During this polishing, the rotary table 3 is actually rotating (relatively speaking, the ferrule 40 is rotating around its axis).
The tip of the ferrule 40 is polished onto the spherical surface which is the rotation locus surface of the cylindrical polishing surface 30a.

In order to polish the tip of the ferrule 40 into a spherical surface with a different radius, it is sufficient to attach another polishing surface plate 30b with a different curvature of the sheet attachment surface to the slide table 15 and perform polishing. If it is desired to polish the sheet into a flat surface, a polishing surface plate 30c having a flat surface to which the sheet is attached may be used. This polishing surface plate can be easily replaced by removing the tension spring 22, replacing the polishing surface plate, and hooking the tension spring 22 onto the new polishing surface plate.
