And, be set in the above-described embodiments second magnet 152 be set.But; As long as it is just passable that tape feeder possesses second magnetic force zone of the following stated; Be not limited to second magnet 152; This second magnetic force zone is: by passed out to element take out the zone element incorporating section 141 the bottom surface below, this second magnetic force zone is set to respect to the first magnetic force zone at the rear of transport direction, and will be passed out to the element that element takes out the element incorporating section 141 in zone and attract the rear to transport direction.For example, be set at the second magnetic force zone in the above-described embodiments and constitute, but also can constitute by a plurality of magnet by one second magnet 152.
And; Also can be in the above-described embodiments, element 140 to be attracted before the end of element incorporating section 141 through magnet 150; Through making tape feeder vibration or tape feeder is tilted, thereby element 140 is moved to the end of element incorporating section 141.
For example, also can be shown in Figure 18 a,, element 140 to be moved to the end of element incorporating section 141 through at the oscillator of the Width of tape feeder vibration and spring etc.And, also can be, shown in Figure 18 B, through transport direction oscillator and the spring etc. of the direction vibration of 45 degree with respect to tape feeder, element 140 is moved to the end of element incorporating section 141.And, also can be, shown in Figure 18 C, through be used in the corrector roll 170 of seeing tape feeder off for example tilt 25 the degree, element 140 is moved to the end of element incorporating section 141 because of the deadweight of element 140.
The formation of Figure 18 A～18C is effective for the element 140 that the LED shown in the sectional view of for example Figure 18 D (Light Emitting Diode) chip is such.Because internal electrode and outer electrode adopt plating Ni (nickel) in resistance and the capacitor, the parts of a part are made up of magnetic material.And with respect to this, in the led chip, for example lead frame is made up of the material that few gold of current loss or silver comprise manyly, electrode 180 also with the flash gold but not nickel plating constitute, its parts are by the influence that is not subject to magnetic force or influence few material and constitute.And because for example constitute with material different such as flash gold and glass epoxy resins with electrode 180 and the element body 181 that one side forms in the bottom surface with LED, so both surperficial slide coefficients are different, in element incorporating section 141, are difficult for sliding.And,, in element incorporating section 141, be difficult for sliding because the contact area of element body 181 and element incorporating section 141 is big.And, because having more, it in element incorporating section 141, is being difficult for such formation of sliding with the surface section of the being formed with difference of electrode 180 that simultaneously forms and element body 181 with the bottom surface.
