PROBLEM TO BE SOLVED: To improve precision in soldered length to the tip part of wire. SOLUTION: A reciprocal unit 1 has wire holding parts 3a to 3e, engaging means 5a to 5e, wire guiding means 7a to 7e, a reciprocally guiding part 4 and a reciprocally driving means 6. Respective wire holding parts 3a to 3e holding the wire W are freely movable back and forth so guide to working units A to E by the reciprocally guiding part 4. The engaging means 5a to 5e are selectively engageable with the wire holding parts 3a to 3e corresponding to them. The engaging means 5a to 5e are driven in the backward and forward direction of the wire holding parts by the reciprocally driving means 6. The tip parts of the wires W corresponding to the wire guiding means 7a to 7e, are respectively guided by the wire guiding means 7a to 7e, and the guiding directions of the wires W are variably composed between a direction tilted in the front downward direction and a horizontal direction to a soldering unit E. By advancing with high precision the wire holding parts 3a to 3e by driving ball screws by the driving means 6, the wires W is fed to the soldering unit E in high precision as well.
