Under the action of the follower 42, when the first bracket 31 moves, the second bracket 41 moves along the first bracket 31 in the X-axis direction, and at the same time, the second bracket 41 moves with the driving member 52 and moves the driving member 52 relative to the support 51, and during the movement of the driving member 52 along the chute 511, the driving member 52 moves in the Y-axis direction, and at this time, the driving member 52 moves in the Y-axis direction with the second bracket 41. Since the guide 61 is provided on the first carriage 31, the second carriage 41 moves from the bottom end of the guide 61 to the top end of the guide 61 or from the top end of the guide 61 to the bottom end of the guide 61 when the second carriage 41 moves along the first carriage 31, and at this time, the second carriage 41 reciprocates in the Z-axis direction.
