A lower side of the holding member 54 has a collar portion 54A, and the collar portion is the housing. Slide on the inner wall. Further, the upper side of the base 52 forms an upper side portion 52A bent inward, and the collar portion 54A abuts against the upper side portion and is caught, so that the upward movement of the pressing member 54 is restricted and it does not fall out. . The pressing member 54 is constantly pushed upward by the spring 56.
The pressing member 54 protruding upward from the base 52 is provided with the window 42.
It has a shape (for example, a square) and a size that allow it to penetrate. An elastic member 58 such as a rubber plate having elasticity with an appropriate thickness is attached to the upper surface of the pressing member 54 with an adhesive or the like. 60 is a magnet. In addition, the magnet catch 43 corresponding to this is provided in the assembly block 30 (FIG. 1). The pressing block 50 is fixedly provided on the base 48 at a position where the pressing member 54 enters the window 42 when the collecting block 30 is tilted, and a part of the elastic member 58 or the elastic member 58 is tilted at the position. All together hold down the sides of the row of single-core optical fibers.

Then, the optical fiber core wire 20 is pushed by the plate 41 (thinner than the width of the slit 40). Then, the pushed optical fiber core wire 20 cannot easily move from the position due to friction with the wall surface of the slit 40. In this state, the optical fiber core wire is not guaranteed to be linear.

Is slightly pushed down while compressing the spring 56. This state is maintained by the action of the magnet 60 and the magnet catch 43. At this time, the plate 41 is also fixed at the same time.
As a result, the slits 40 contact each other in the slit 40
A group of optical fibers that are horizontally aligned in the row and elastically clamped by the holding member 54 is obtained.

易に得られる。(1) Since it is sufficient to insert the optical fiber core wire into the slit, the single-core optical fibers can be easily aligned and assembled. Moreover, since the handling is performed while maintaining the straight state, the possibility of scratching the coating of the optical fiber core wire is reduced. (2) By simply tilting the main body 32 in which the plurality of optical fiber core wires 20 are aligned in the slit 40 in the upright state, the group of the optical fiber core wires 20 is securely held by the pressing member 54 fitted in the window 42. Is clamped. Therefore, it is easy to obtain a group of optical fibers which are aligned in contact with each other in a horizontal state of one row, which is easy to carry out the next process such as tape formation.
