In addition, an unillustrated suction release mechanism for releasing the suction and holding of the electronic component 50 into the notch 215 by air suction is provided in the discharge portion 230 . As the suction release mechanism, for example, it may be a mechanism that ejects air and stops or weakens the flow of the sucked air. When the turntable 212 rotates and the notch 215 coincides with the passage hole 218, the holding of the electronic component 50 in the notch 215 is released by the above-mentioned attraction release mechanism, and the electrons that have moved on the upper surface 216 of the base 214 so far The component 50 falls from the notch 215 to the passing hole 218 , and then falls through the passing hole 218 to the inside of the cylindrical member 231 . Furthermore, it is preferable that the inner diameter of the upper cylindrical portion 233 is larger than the lengthwise dimension of the electronic component 50, and the inner diameter of the lower cylindrical portion 234 is larger than the longitudinal dimension of the electronic component 50 and smaller than the diameter of the upper cylindrical portion 233. the inside diameter of.

Furthermore, it is preferable that the inner surface 232 of the cylindrical member 231 is a smooth low-friction surface so that the electronic component 50 can slide down smoothly. For example, it is preferable to process the surface on resin such as fluororesin.

A pressing pin 236 for forcing the electronic component 50 to drop from the notch 215 is provided on the discharge portion 230 . The pressing pin 236 is disposed above the notch 215 matched with the passing hole 218 . The pressing pin 236 is a rod-shaped member extending in the vertical direction, and is driven in the vertical direction by an actuator (not shown) or the like. When the pressing pin 236 is driven downward, the electronic component 50 in the notch 215 is pressed downward, passes through the hole 218 and falls into the cylindrical member 231 . By being pressed by the pressing pin 236 , the electronic component 50 falls out of the notch 215 without being caught in the notch 215 .
