5 is attached. Each of these heads has suction nozzles 22 and 24 and a dispenser 26 for applying a bond. Here, the suction nozzle 22 is a commonly used flat nozzle, and is of a type in which the posture of the sucked optical fiber element 8 is not accurately held, whereas the suction nozzle 24 conforms to the shape of the optical fiber element 8. The optical fiber element 8 having the suction surface
Is transported while maintaining its posture accurately. of course,
Instead of the flat nozzle, the suction nozzle 22 may be of the same type as the suction nozzle 24. The slide table 20 reciprocates in the Y direction by a driving unit (not shown), and the first transfer head 21, the second transfer head 23, and the bond applying head 25 move integrally and synchronously with the slide table 20. .

A supply section 30 for the optical fiber element 8 is provided on the side of the transport path 11. A plurality of trays 33 supported on a plate 32 are mounted on a turntable 31 of the supply unit 30. In the tray 33, a plurality of optical fiber elements 8 are arranged and stored. Tray 33

The control unit 55 monitors the detection timing of the mark detection signal while gradually rotating the motor 43, and stops the motor 43 according to the detection timing, thereby aligning the fiber 8b in the θ direction in the same manner as in FIG. It can be carried out. Therefore, FIG.
The rotation unit for rotating the optical fiber element 8 and the positioning unit shown in FIG. 3B constitute a positioning unit.

The optical fiber device mounting apparatus is configured as described above, and the operation will be described below. FIG.
In, the carrier 1 supplied from the stocker 10 moves on the transport path 11 and reaches the movable table 12, where it is positioned. In parallel with this operation, the supply unit 30
The optical fiber element 8 is picked up from the tray 33 by the first transfer head 21 and placed on the temporary placement stage 40. Then, the positioning of the fiber 8b in the θ direction is performed by the positioning means.

The aligned optical fiber element 8 is picked up by the second transfer head 23. Since the suction nozzle 24 mounted on the second transfer head 23 is in accordance with the shape of the optical fiber element 8, the state where the optical fiber element 8 is aligned without causing displacement during movement is determined. It is mounted on the package 3 of the carrier 1 while holding it. At this time, since the optical fiber element 8 has been aligned in the θ direction by the temporary placement stage 40, the tip end surface of the fiber 8b can be mounted in the correct direction when mounted on the package 3.
