A solder supply system that judges whether solder cup 70 is set on solder supply device 26. In a case in which it is judged that the solder cup is set on the solder supply device, reading a barcode by barcode reader 170 is allowed. In contrast, in a case in which it is judged that the solder cup is not set on the solder supply device, reading a barcode by the barcode reader is restricted. That is, reading a barcode by the barcode reader before the solder cup is set inside outer tube 72 is restricted, while reading a barcode by the barcode reader is allowed when the solder container is set inside outer tube 72. Thus, verification work is only able to be performed for solder cups actually set on solder supply device 26, which prevents operator mistakes and enables verification work of solder containers to be performed appropriately.
