Zusammenfassung:	PURPOSE: To stably and with a high speed feed electronic components by providing an adjustable shutter for enclosing the components before taking out the electronic component from a pocket of a tape. CONSTITUTION: A shutter mechanism 26 includes spring blades 28 formed of a stainless steel and a component feeding tape 14 is index-acted and each pocket 16 is continuously positioned at a pick-up station to open successively each pocket. When a cover is removed, the shutter mechanism 26 is positioned on the top side of the opened pocket and a vacuum spindle 22 is lowered and the suction apex part 24 pushes to open a pair of blades 28 to make them open. Then, while the blades keep a component at its proper posture, vacuum is switched on and the blades are moved in the axial direction to take out the component from the pocket of the tape. In addition, the crosssectional area or the suction apex part is made larger than the surface area of the top face of the component.
