<p>PROBLEM TO BE SOLVED: To surely keep a switch cam projecting in an object detecting mechanism and surely rotate the switch cam even with weak force of a moving object pushing the switch cam. SOLUTION: An object detecting mechanism 17 placed on a containing position of a moving object 1 supported rotatably and detecting whether or not a moving object is contained is provided with a plate shape switch cam 34 of which tip end is attached projecting to the containing position so that one side edge part is capable of touching the moving object when it is contained, an energizing support means 35 supporting the switch cam 34 rotatably around a base end side of one side edge part along the moving direction of the moving object and energizing opposite to the switch cam in the rotation direction and a switch means 36 detecting the existence of the rotation of the switch cam. On one side edge part, a concave 34a is formed at a part where the moving object first touch when it is contained.</p> |
