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.

The ejection part 230 is provided with a pressing pin 236 for forcibly dropping the electronic component 50 from the drop hole 215 . The pressing pin 236 is disposed above the drop hole 215 matching 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 drop hole 215 is pressed downward and falls into the inside of the cylindrical member 231 . By pressing with the pressing pin 236 , the electronic component 50 is surely dropped from the drop hole 215 without being caught in the drop hole 215 .

Furthermore, an airflow generating part 237 for dropping the electronic component 50 from the drop hole 215 by the flow of air may be provided in the discharge part 230 instead of the pressing pin 236 or additionally.

The bottom plate portion 2D of the box body 1 is parallel to and opposite to the wall surface 241a with a gap.

In the wall portion 241, a recess 242 extending in the vertical direction and opening toward the wall surface 241a side is formed. Inside the recess 242, an opening and closing mechanism 260 for sliding the door member 3 is arranged. The opening and closing mechanism 260 has a drive pin 261 provided movably in the vertical direction along the bottom surface of the recess 242 . The front end of the drive pin 261 protrudes from the wall surface 241a. The driving pin 261 is vertically movably supported, for example, along a guide groove provided on the bottom surface of the recess 242, and is reciprocally driven vertically by an actuator or the like. In the recess 242 of the wall part 241, the reader-writer 243 which reads and writes information with respect to the RFID tag 5 non-contact is arrange|positioned. The reader/writer 243 is an example of the information read/write unit. Furthermore, the upper hook portion 251 and the lower hook portion 252 may not have the same shape.

During the conveyance of the non-vibration conveyance part 220, the conveyance number of the electronic component 50 is counted by the 1st component detection part 271. In addition, the number of electronic components 50 dropped from the drop hole 215 and finally housed in the case 1 is counted by the fourth component detection unit 274 including the upstream passage detection unit 275 and the downstream passage detection unit 276 . When the number of electronic parts 50 accommodated in each box body 1 reaches a specified number, the conveyance of the electronic parts 50 by the conveying part 210 is interrupted, and after the setting part 240 is replaced with a new empty box body 1, the delivery of the electronic parts 50 to the box body 1 is resumed. Electronic components 50 are accommodated. Furthermore, in the above-mentioned continuous operation of the plurality of conveying lines, that is, the first conveying line 210A, the second conveying line 210B, and the third conveying line 210C, it is desirable to control each line independently, but it is also possible to control the plural conveying lines synchronously. action.

In the parts storage device 200 of the embodiment, when the cassette body 1 is set in the installation part 240, various information can be written on the RFID tag 5 of the cassette body 1 by the reader-writer 243.
