Abstract: A first conveyor belt and second conveyor belt are disposed on guide rail which is disposed so as to extend in a circuit substrate conveyance direction. Then, the circuit substrate supported by both the conveyor belts of the first conveyor belt and the second conveyor belt is held by substrate holding device, and work is performed on the held circuit substrate. In the transfer device having such a structure, for example, when the circuit substrate on which an operation has been completed is conveyed out by the second conveyor belt, a new circuit substrate is conveyed into the transfer device by the first conveyor belt. In this way, it is possible to perform printing work on a new circuit substrate at an early stage and shorten a cycle time.

Abstract: A solder supply device is provided with solder cup housing liquid solder that is tubular and open at one end, a positive/negative pressure supply device capable of controlling the pressure inside the solder cup, a supply nozzle for dispensing solder from the solder cup, and a solder cutting device that cuts solder supplied from the supply nozzle by ejecting compressed air. Solder is supplied from the supply nozzle by increasing the pressure inside the solder cup using the positive/negative pressure supply device. When stopping the supply of solder from the supply nozzle, the pressure inside the solder cup is decreased using the positive/negative pressure supply device, and solder is cut by the solder cutting device to match the timing of pressure inside the solder cup decreasing.
