PROBLEM TO BE SOLVED: To improve a holder mounting device that is provided for detachably mounting an object holder to a holding head.SOLUTION: When a holding head 130 holds a component holder 132, a connecting protrusion 214 of a hook 202 is engaged with an inclination engagement surface 356 of a bar 350 of a holder stocker with the descent. By the action of a slope, the hook 202 turns to the disengaged position, and passes a held part 142 of the component holder 132 (Fig. 25(a) to (c)). In the state where the holding head 130 descends to a descent edge position, there is a gap between the held part 142 and the holding head 130. However, the held part 142 is sucked and held by a negative pressure (Fig. 25(d))), and then rises and takes out the component holder 132 from the holder stocker (Fig. 25(e) to (g)). The hook 202 is turned to an engagement position by the biasing of a spring, and an engaging protrusion 240 is positioned at the lower side of the held part 142 (Fig. 25(h)). Even if an excessive force is applied to the component holder 132, the hook is engaged with an engaged surface 153, thereby preventing the detachment of the component holder 132. |
