Title: Ink replenishing tool
Inventor: NISHIMURA KAZUAKI
IPC: B41J2/175
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To replenish a supply ink to a device filled with felt, or the like, by providing a ventilation hole communicating the area above the liquid level of the ink in the space inside the cylinder to at least either a cylinder or a piston as well as by providing a switching member for opening or closing the ventilation hole. SOLUTION: When a ventilation hole 11c is opened by pulling out a plug member 13, the air in the area above the liquid level of an ink 1 inside a cylinder 10 is introduced from the outside via the ventilation hole 11c so as to provide an atmospheric pressure in the inside of the area. Owing to the pressure difference with respect to the inside of a cartridge 2 in a reduced pressure state, the ink 1 in the cylinder 10 is pressed downward so as to be supplied into the ink cartridge 2 in the reduced pressure state via an injecting member 12. Since the inside of the ink cartridge 2 is in the reduced pressure state, a sufficient amount of the supplied ink 1 can permeate quickly to every corner of the inside without being disturbed by air even in the case highly compressed felt 3 exists therein so as to replenish the supply ink.
