Title:
METHOD AND APPARATUS FOR REFILLING LIQUID IN LIQUID STORAGE CONTAINER
Document Type and Number:
Japanese Patent JP3658328
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for refilling a liquid in which the liquid can be accurately refilled in a liquid tank used in a liquid jet apparatus or the like regardless of a remaining amount of the liquid and without requiring complicate control and constitution at the refilling time.
SOLUTION: There are provided a liquid extraction means for extracting the liquid remaining in the liquid tank 1 from a liquid take-out port 4 through which the liquid is supplied to a liquid discharge head, means for reducing a pressure inside the liquid tank 1 after the liquid is extracted through the liquid take-out port 4, and filling means for filling a liquid in a supplementary liquid tank 11 from the liquid take-out port 4 to the liquid tank 1 with the utilization of a pressure difference between the supplementary liquid tank 11 and the liquid tank 1. The liquid remaining in the liquid tank 1 is once extracted through the liquid take-out port 4. The pressure of the liquid tank 1 after the liquid is extracted is reduced through the liquid take-out port 4. The liquid is refilled from the liquid take-out port 4 with the utilization of the pressure difference between the liquid tank 1 and the replenishment liquid tank 11.
