         3 . The coating system according to  claim 2 , wherein
 the second arm has an arm length shorter than an arm length of the first arm.   
     
     
         4 . The coating system according to  claim 2 , wherein
 the fixed-type operation robot further includes a third arm, the third arm having a base end side supported to a tip side of the second arm, the third arm rotating around an axis parallel to the vertical axis, the third arm extending downward along the axis.   
     
     
         5 . The coating system according to  claim 4 , wherein
 the fixed-type operation robot further includes:
 a fourth arm having a base end side supported to a tip side of the third arm, the fourth arm turning around an axis perpendicular to the vertical axis; 
 a fifth arm having a base end side supported to a tip side of the fourth arm, the fifth arm turning around an axis parallel to a turning axis of the fourth arm; and 
 a tip jig having a base end side attachably/detachably supported to the fifth arm, the tip jig turning with respect to the fifth arm. 
   
     
     
         6 . The coating system according to  claim 5 , wherein
 the fifth arm maintains a relative posture to the third arm even when the fourth arm turns with respect to the third arm.   
     
     
         7 . The coating system according to  claim 6 , wherein
 the third arm internally includes a power source to turn the fourth arm and the tip jig.   
     
     
         8 . The coating system according to  claim 7 , wherein
 the third arm includes an internal pressure chamber to house the power source.   
     
     
         9 . The coating system according to  claim 5 , wherein
 a direction of a turning axis of the tip jig with respect to the fifth arm is changeable by changing a mounting direction of the tip jig with respect to the fifth arm.   
     
     
         10 . The coating system according to  claim 5 , wherein
 the tip jig includes a locking part that locks the open/close member,   the tip jig has a turning axis with respect to the fifth arm offset from the locking part in a horizontal direction, and   the coating system further includes a determiner configured to determine a lock state of the open/close member by the tip jig based on an output from a power source to turn the tip jig.   
     
     
         11 . The coating system according to  claim 1 , further comprising
 a conveying device that conveys the vehicle in the conveyance direction, wherein   the fixed-type operation robots are installed by one on the upstream side and the downstream side of the plurality of coating robots such that the fixed-type operation robots are disposed across the conveying device.   
     
     
         12 . The coating system according to  claim 1 , wherein
 the plurality of coating robots includes at least a pair of coating robots, the coating robots having a first axis and a first arm that rotates around the first axis, and   the pair of coating robots is installed such that the respective first axes are positioned on an identical straight line parallel to the conveyance direction and the respective first arms extend in a direction away from one another.   
     
     
         13 . The coating system according to  claim 12 , wherein
 the pair of coating robots has an arm configuration symmetrical with respect to a surface perpendicular to the identical straight line at an intermediate position of the pair of coating robots.   
     
     
         14 . The coating system according to  claim 13 , further comprising
 a conveying device configured to convey the vehicle in the conveyance direction, wherein   the pair of coating robots is installed for every one pair at symmetrical positions across the conveying device, and   the coating robots at diagonally opposite positions mutually have the identical arm configurations.   
     
     
         15 . A fixed-type operation robot comprising:
 a base fixed to an inside of a coating booth;   a first arm having a base end side supported to the base, the first arm turning around a first axis in a vertical direction;   a second arm having a base end side supported to a tip side of the first arm, the second arm turning around a second axis parallel to the first axis;   a third arm having a base end side supported to a tip side of the second arm, the third arm rotating around a third axis parallel to the second axis, the third arm extending downward along the third axis;   a fourth arm having a base end side supported to a tip side of the third arm, the fourth arm turning around a fourth axis perpendicular to the third axis;   a fifth arm having a base end side supported to a tip side of the fourth arm, the fifth arm turning around a fifth axis parallel to the fourth axis; and   a tip jig attachably/detachably fixed to the fifth arm, the tip jig operating an open/close member provided at a front or a rear portion in a vehicle conveyed in a predetermined conveyance direction in the coating booth.
