PURPOSE: A shutter improving device for supplying a tantalum element is provided to enhance a supplying efficiency of the tantalum element by automatically opening and closing a shutter so as to allow the tantalum element to be supplied. CONSTITUTION: A driving part(120) includes a rotational plate(123) of which a sensing pin(124) is engaged with one end of the rotational plate(123). The center portion of a shutter opening/closing cam(121) is attached to the other end of the rotational plate(123) by means of a fixing pin(122). The rotational plate(123) rotates around the fixing pin(122). Slide pieces(112) are attached to a lower portion of a shutter(111). An elastic member(112a) is located between the slide pieces(112) of which free ends are located between both sides of the shutter opening/closing cam(121). A guide plate(113) having an insertion hole(113b) formed there through is positioned at the lower surface of the shutter(111). The slide pieces(112) are inserted into the insertion hole(113b). The shutter(111) of a shutter opening/closing part(110) is opened and closed by the shutter opening/closing cam(121). A lower portion of the bracket is attached to the lower portion of the shutter opening/closing part(110) in order to support the shutter opening/closing part(110) as a fixing part. |
