Abstract
An turning shaft 1 which turns a torch with keeping it on a normal line to the turning shaft is connected with an end of an first rotation shaft 2 which is arranged at a right angle to the turning shaft 1. A second rotation shaft 3 is connected with the first rotation shaft 2. Both the rotation shafts are connected with each other through a first arm 4, and a second arm is connected with with the rotation shaft 3. a first fixed gear 14 is fixed to the first rotation shaft 2, and a second fixed gear 15 is fixed to the second arm 5. a middle gear 16 is arranged between both the fixed gears, and a rotation axis 16c is fixed to the first arm 4. a motor 17 is mounted above the upper bent portion 4a and a gear 17a is engaged with the first fixed gear 14. While rotating the first arm by angle .theta. in the direction of arrow a, the second arm 5 is rotated by angle 2.theta. in the direction of arrow b, wherein the angle made between the extension of line of the turning shaft and the extension of line of the second arm 5 is .theta..
