摘要

A second tube (T3) constituting a tube pump is connected to a first tube (T1) connected to a suction hole (10e) in an above capping member (10) via a connecting member (21). The first tube (T1) connected to the suction hole (10e) formed in a capping member (10) is made of material excellent in the gas-barrier characteristic and preferably, butyl rubber is used. The second tube (T3) constituting the tube pump is made of elastic and restorable material to fulfill the function of a tube pump and preferably, silicon rubber is used. ??Hereby, the vaporization of an ink solvent from the tube (T1) which is inferior in the gas-barrier characteristic can be effectively inhibited and the moist state of an ink solvent in the capping member can be maintained for a long term.
