PROBLEM TO BE SOLVED: To selectively change at least either a stop position in a stop station on a moving path of an electronic part holding head or a position in a direction orthogonal to the moving path. SOLUTION: Twelve rotating boards 80 are attached to the main shaft 68 while rotation is allowed, and accelerating, decelerating, stopping and constant- speed-rotating are performed by engagement of a roller 130 for a hourglass- shaped cam with hourglass-shaped cams 132a and 132b, and constant-speed- rotating is allowed by engagement with a constant speed rotating board 100 by an engagement device 104. A width of the part orthogonal to an axis of a cam groove of the hourglass-shaped cams 132a and 132b is widened, and a part suction position and a part attaching position are changed to be of two types in a circumferential direction. A rising/lowering board 194 which is provided to the rotating board 80 is, in a roller 196 for fixed cam, engaged with a cam groove 200 of a fixed cam 198 for raising/lowering, and a width of the part corresponding to each position of part suction, imaging and part attaching of the cam groove 200 is widened, and height of an electronic part holding head 190 at each of these positions is changed in two steps. |
