Claim Text:
1. A feeding device movably disposed through a cover device so as to face a work region shielded by the cover device, for holding an object and controlling an attitude of the object, comprising: a first rotary saddle that is rotatable about a first axis; a second rotary saddle that is disposed on the first rotary saddle and rotatable about a second axis in a direction different from the first axis; a holding device that is disposed on the second rotary saddle to hold the object; a first driving device that is disposed outward of the cover device with respect to the work region to rotate the first rotary saddle; a second driving device that is disposed outward of the cover device with respect to the work region to rotate the second rotary saddle, a feed base that supports the first and second driving devices, the feed base having a hollow portion; a first transmission shaft that is disposed inside the hollow portion and coupled to the first driving device; a first reduction gear mechanism that decelerates rotation of the first transmission shaft and outputs the decelerated rotation, the first reduction gear mechanism having a first output shaft formed of a hollow shaft; a second transmission shaft that is disposed through the first output shaft, the second transmission shaft being disposed parallel to the first axis inside the hollow portion and coupled to the second driving device; and a second reduction gear mechanism that decelerates rotation of the second transmission shaft and outputs the decelerated rotation, the second reduction gear mechanism having a second output shaft coaxial with the second axis, wherein the first rotary saddle is fixed to the first output shaft and rotatably journaled to the second transmission shaft, and the second rotary saddle is fixed to the second output shaft.
