点があった。Most conventional optical fiber polishing equipment employs a mechanism that keeps the optical fiber holder mechanism stationary and slides the polishing surface side, and also uses a mechanism that moves the optical fiber holder mechanism side to perform polishing. Parallel movement, which is essential for polishing, relies on simple linear reciprocating motion in the X-axis direction, linear reciprocating motion in the Y-axis direction, or simple circular motion, which makes it impossible to effectively utilize the polishing surface. There were drawbacks such as extreme wear on the polished surface and lack of good polishing finish.

磨を得るようにしたことを特徴とするものである。As described below, the present invention adopts a polishing surface stationary method in which the flat polishing surface side is kept stationary and one end surface of an optical fiber is slid onto the polishing surface in the stationary state under pressure contact. , the optical fiber is slid over a wide area of the polishing surface by a combined motion of reciprocating motion in the X-axis direction parallel to the static polishing surface and reciprocating motion in the Y-axis direction, and both methods are applied. The purpose of the present invention is to provide an optical fiber polishing device that appropriately polishes the end face of an optical fiber using a combination of the following: A gear is provided, and the motion in the Y-axis direction is alternately transmitted to the one-way gear to cause the one-way rotation to be performed alternately, thereby accurately switching between forward and reverse rotation of the screw shaft, and an optical fiber holder.

ている。As mentioned above, the one-way gears 16 and 17 are key-coupled with the screw shaft 15 only when rotating in one direction, and have the function of rotating it in one direction, either forward or reverse. The optical fiber I including the movable table 6 is inserted through the sliding engagement between the eccentric pin 14 and the guide groove 12.
When the holder mechanism is reciprocating in the Y-axis direction, if the one-way gear 16 and the rack 18 are engaged,
%, the same gear 16 rotates forward and backward in the Y-axis direction on the rack 18 as the movable table 6 reciprocates in the Y-axis direction, and only when the gear 16 rotates in one direction (for example, forward rotation) does the screw shaft rotate. 15 in the same positive direction, thereby gradually moving the moving table 6 in one direction of the X-axis, thereby compressing the one spring 24 and switching the gear (as shown in FIG.
