保持される。 In FIG. 4, when the conveyance chain 7 travels in the direction of arrow E1 , the cap nut 14 of the first holding claw 11
The top of the is a rotary plate 3 rotating in the two directions of arrow E.
It engages with the inclined surface 37 of No. 6. Next, the rotating plate 36
As a result of the rotation, the top of the cap nut 14 is pushed down by the inclined surface 37 and presses the compression spring 15. Therefore, the first holding claw 11 is lowered to the position indicated by the chain double-dashed line in FIG. 1a and the position shown in FIG. 3b.
At this time, when the printed circuit board 1 is inserted in the direction of arrow E3 , the side edge of the printed circuit board 1 will be inserted into the first holding claw 1.
It is placed on the claw part 12 of 1. At this time, the second holding claw 21 does not move in the vertical direction, so it does not engage with the printed circuit board 1. Next, when the conveyance chain 7 further travels and the top of the cap nut 14 separates from the inclined surface 37, the pressure on the cap nut 14 is released and the first holding claw 11 is raised by the restoring force of the compression spring 15. , return to the original position. At the same time, the printed circuit board 1 also rises and engages with the inclined surface 22 of the second holding claw 21. Therefore, the printed circuit board 1 is pressed vertically and laterally by the upward pressing force of the compression spring 15 of the first holding claw 11 and the inclined surface 22 of the second holding claw 21. 1 is securely held by the respective holding claws 11 and 12.

Therefore, the sprocket 3 can be connected via the bolt 33.
2 also moves in the same direction, so the conveyance chain 7 is strongly stretched. Furthermore, when loosening the tension on the conveyor chain 7, it is sufficient to turn the bolt 40 in the opposite direction to that described above, and as a result, the slide plate 38 slides due to the restoring force of the conveyor chain 7 being stretched, and the sprocket 32 moves in the direction of the arrow. It moves in the direction opposite to the direction F, and the tension of the conveying chain 7 is loosened.
