PROBLEM TO BE SOLVED: To obtain the residual quantity of a solder stored in a solder container, while restricting increase in cost.SOLUTION: When making the solder container rotate from a vertical attitude to a horizontal attitude, the vane part 70 of a vane member 62 is made to rotate in a rotary cylinder 50 from the position abutting to a protrusion part 71 of a cylinder body 60 to the position abutting to a protrusion part 74. The time is measured from the time point the vane part 70 is detected to separate from the protrusion part 71 by a vertical switch 72 to the time point the same is detected to abut with the protrusion part 74 by a horizontal switch 76, and in a case the time is longer, the mass of the solder container is larger than in a case the time is shorter, acquiring that a solder residual quantity is large. Thus, without using a solder height sensor, a level sensor and the like, the solder residual quantity is acquired, and increase in cost is restricted. |
