PURPOSE:To obtain a stable and reliable state of a device by a method wherein the travel of a movable member in the inserting direction is regulated by a regulating means. CONSTITUTION:When an ink cartridge 4 is inserted into an ink cartridge guide, a tapered surface 4A of the ink cartridge 4 abuts against a projected part 34C of a lock lever 34, presses up the projected part 34C to rotate the lock lever 34 clockwise about a fulcrum 34A, and releases a movable member 31 from an engaging claw 34B. In this manner, the movable member 31 is allowed to be traveled leftward. Then, the ink cartridge 4 is abutted against a movable member shielding part 31A, the ink cartridge 4 is moved against the spring force of a coil spring 32 together with the movable member 31 by conducting an ink cartridge inserting action succeedingly, and a hollow needle 20 is inserted into the ink cardridge 4 through a hollow needle insertion hole 31B. In this manner, the ink cartridge 4 can be positively loaded on a loading part. |
