The component holder is rotatably supported on this second rotating shaft 30 with a member 9 engaged with the key 31 in the rotational direction. and.

Rotation is transmitted by a first rotating shaft 25, a second rotating shaft 30, and a gear 33 such as a bevel gear.

Next, the operation of the present invention with the above configuration will be explained. First, the plane rotation A of the component 9 of the component holder is as shown in FIG.
The first electromagnetic clutch 20 is connected, and the first! Release magnetic brake U. Further, the second ILC magnetic clutch 26 is disengaged, and the 2111th magnetic brake 29 is operated for braking, so that the rotation path is from the motor rotation shaft 16 to the first electromagnetic clutch 20, the hollow rotation shaft 17, and the second nozzle 14. is transmitted to the second housing 14 and the second 'rlL magnetic brake 2.
The first rotating shaft 5, which is integrally locked by the second housing 14, rotates integrally with the second housing 14, and the component receiver connects the member 9 to the second housing 14 via a gear 33 whose rotation is fixed. rotated as one. That is, the component holder member 9 is rotated in a plane A around the axis of the motor rotation shaft 16 to an arbitrary angular position of 3600 degrees.

Next, the side rotation B of the component receiver 9 releases the first electromagnetic clutch 20 and puts the first electromagnetic brake 24 into braking operation, as shown in FIG. Also, the second electromagnetic clutch 26 is connected and the second electromagnetic brake 29 is released. As a result, the rotation of the hollow rotating shaft 17 and the second housing 14 integrated therewith is stopped by the first electromagnetic brake 24.
Since the motor rotation shaft 16 and the first rotation shaft 25 are directly connected by the second electromagnetic clutch 26, the rotation of the motor rotation shaft 16 rotates the first rotation shaft 5, and the rotation of the first rotation shaft 25 is transferred to the gear 33. is transmitted to the second rotating shaft 30 via. Due to this rotation of the second rotating shaft 30, the component receiver member 9 is rotated integrally with the second rotating shaft 30. That is, the component holder member 9 is laterally rotated B to an arbitrary angular position 18d around the axis of the second rotating shaft 30 that is orthogonal to the axis of the motor rotating shaft 16.
