PROBLEM TO BE SOLVED: To easily exchange a container without incorrect fitting of right and left components or without any degradation of the liquid caused by the adhered residual liquid by storing liquids of different kinds in a plurality of containers, and providing an engagement part capable of being positioned to a positioning part of a body on an inlet side eccentric end part of a cartridge. SOLUTION: A cartridge 4 to store a liquid is fixed to a forward end of a case 1 in an attachable/detachable manner. A piston is slidably provided in storage chambers 5, 6 capable of storing two kinds of liquid, and the liquids are discharged from discharge ports 11, 12. In a method for exchanging the cartridge, the cartridge 4 is turned with respect to the body 1 with the piston left behind in the containers 5, 6, and detached from the body 1. Then, a new cartridge 4 is positioned to a recessed part 30 of an upper frame 2, and turned while a flange part of a storage chamber receiver is pressed against a bulkhead 2b, etc., and the turn is completed when it is abutted on a stopper part, and the cartridge 4 is fixed to the body 1. |
