PROBLEM TO BE SOLVED: To insert a work clamped by a work clamp unit, lower it into a carrier tape smoothly and stop operation of a work clamp unit required. SOLUTION: A cam 48 consisting of a semicircular part 48a and a circumference 48b is touched by an arm 46 swinging on a fulcrum 46a through a cam follower 49. When the semicircular part 48a touches the cam follower 48, the arm 46 swings counterclockwise around the fulcrum 46a by the force of a spring 47 and a roller 57 of the arm 46 lowers a work clamp body 52 and inserts a work 10 into a carrier tape 40. When the circumference part 48b touches the cam follower 49, the arm 46 swing clockwise around the fulcrum 46a lifts up the work clamping body 52. When a electromagnet 56 pulls the arm 46, the arm 46 stops action against a work clamp body 52. |
