Claim of US Patent No. 9,883,597

1. A solder supply device comprising:
a solder container housing liquid solder that is tubular, is open at an opening provided at a first end of the solder container,
and includes a bottom at a second end of the solder container;

an outer tube inside which the solder container is stored;
a nozzle, for ejecting solder from the solder container, that is inserted into the solder container;
a piston that is provided on an outer circumferential section of the nozzle and that is engaged inside of the solder container
from the opening of the solder container; and

a demarcating member that demarcates an air chamber with at least one of the following: a surface of the second end of the
solder container, an adapter attached to the surface of the second end of the solder container, or a surface of the piston
facing the opening of the solder container,

wherein the solder supply device supplies solder from a tip of the nozzle by relatively moving the solder container and the
piston by supplying air to the air chamber such that the piston advances inside the solder container between a first position
and a second position, the piston being closer to the opening of the solder container in the first position than in the second
position, and

wherein, in the second position of the piston, the solder container and the piston are removable from the outer tube as a
single assembly from the outer tube.
