[0006]

[Action]

 FIG. 1 shows a state in which the amount of the measured liquid is minimized. When the push-down plates 30 and 30 are pushed down from the state shown in the figure until they come into contact with the uppermost upward step 12a, the piston-equipped member 32 becomes an outer peripheral portion of the top plate 36. Since the lower surface is engaged with the upper end of the outer cylinder portion 6, its position is held and does not descend, but the cylinder 26 and the liquid flow pipe 14 descend against the bias of the coil spring 24, and therefore the cylinder 26 The inside becomes negative pressure, the discharge valve 20 opens, and a predetermined amount of the liquid in the container is sucked into the cylinder 26 through the suction pipe 23 and the liquid flow pipe 14, and then from this state, the pressing plates 30, 30 are When the push-down is released, the elastic restoring force of the coil spring 24 causes the cylinder-mounted member 26, the liquid flow pipe 14 and the piston-equipped member 32 to rise with respect to the tubular member 5, and the weighing is completed. The liquid in the cylinder thus sucked is removed from the liquid measuring device 25 from the tubular member 5, and the piston 33 is pushed into the cylinder 26 to be discharged from the discharge pipe portion 29, and after use, the upper portion of the outer cylinder portion 6 is removed. Insert the liquid measuring instrument 25 into the inside.

Further, by appropriately rotating the liquid measuring device 25 with respect to the tubular member 5, the amount of the measuring liquid can be changed. For example, from the state shown in FIG. 1, by appropriately rotating the liquid measuring device 25, the positions of the push-down plates 30, 30 are changed from the uppermost upward step 12a to the lower upward step 12b, and then the pressing plate 30 is moved. When is pushed down, the pushing amount of the cylinder 26 against the member 32 with the piston becomes large, so that the liquid sucked into the cylinder 26 increases and the amount of the measured liquid becomes large, and as shown in FIG. When the push-down plates 30 and 30 are located above the bottom surface of the vertical dividing groove 11, the amount of measured liquid becomes maximum.
