As shown in FIG. 8, the drive pin 261 is engaged with the slider 4 of the case 1 held by the holding portion 250 . The shutter member 3 of the case 1 shown in FIG. 8 slides forward (upward in FIG. 8) so that the protrusion 4b of the slider 4 is fitted into the front recess 26a, and the opening 6 is closed by the shutter member 3. ing. On the other hand, the drive pin 261 has moved upward. When the case 1 whose opening 6 is closed by the shutter member 3 is held by the holding portion 250 when the drive pin 261 is positioned upward, the drive pin 261 moves toward the lower opening of the slider 4 shown in FIG. It is inserted into the portion 4c and positioned between the front end plate portion 4d and the rear end plate portion 4e.

When the drive pin 261 moves downward in FIG. 8 from this state, the drive pin 261 contacts the rear end plate portion 4e of the slider 4 and pushes the slider 4 downward to slide it. As the slider 4 slides downward, the shutter member 3 slides rearward in the case 1 . Then, as shown in FIG. 9, the convex portion 4b of the slider 4 is fitted into the recess 26b on the rear side, and the opening 3a of the shutter member 3 is aligned with the opening 6 of the case 1 so that the opening 6 is opened. When the drive pin 261 returns upward from this state, the drive pin 261 contacts the front end plate portion 4d of the slider 4 and pushes the slider 4 upward to slide it. As the slider 4 slides upward, the shutter member 3 slides forward in the case 1, and as shown in FIG. .

As shown in FIG. 10 , the second conveying section 310 is arranged from below the first discharge section 230 to above the case 1 installed in the installation section 240 .

Passing hole 218 has a size through which electronic component 50 passes. Directly below the passage hole 218, the introduction port 311 of the second conveying section 310 is arranged. When the turntable 212 rotates and the notch 215 aligns with the passage hole 218, the electronic component 50 is released from the notch 215 by the suction release mechanism, and has been moving on the upper surface 216 of the base 214 until then. The electronic component 50 falls from the notch 215 into the passage hole 218 . Then, the electronic component 50 passes through the passage hole 218 and falls into the second conveying section 310 from the introduction port 311 .

The push pin 236 has a function of forcibly dropping the electronic component 50 from the notch 215 . A hold down pin 236 is positioned above the notch 215 in line with the through hole 218 . The push pin 236 is a rod-shaped member that extends vertically, and is driven vertically by an actuator (not shown) or the like. When the push pin 236 is driven downward, the electronic component 50 in the notch 215 is pushed downward and dropped through the passage hole 218 onto the second transport section 310 . By being pushed by the push-down pin 236 , the electronic component 50 reliably falls out of the notch 215 without being caught in the notch 215 .

Instead of or in addition to the push pin 236, the first discharge section 230 may be provided with an air flow generating section 237 that causes the electronic component 50 to drop from the notch 215 by air flow.

The plurality of nozzles 343 are connected to a compressed air supply source (not shown) and joined to the cover 342 so as to supply compressed air into the cover 342 . Compressed air is supplied from the compressed air supply source into the cover through a nozzle. Compressed air supplied from the nozzle 343 into the cover 342 passes through the pores of the second porous portion 341 and is blown into the tubular member 313 . The cover 342 functions to prevent air from escaping from the second porous portion 341 to the outside of the tubular member 313 .

The tips of the plurality of nozzles 343 are joined to the cover 342 in an inclined state so as to face downward, which is the conveying direction of the electronic component 50, and face upward in the opposite direction. As a result, the electronic component 50 conveyed inside the end portion 312 is floated by the compressed air blown from the plurality of nozzles 343 . For this reason, a situation in which a plurality of electronic components 50 are clogged and stagnate in the end portion 312 is less likely to occur, and as a result, the electronic components 50 eventually drop smoothly. That is, the compressed air assists the transportation of the electronic component 50 .
