PROBLEM TO BE SOLVED: To provide a needle structure in a loading apparatus which restrains liquid leakage from a needle hole of a needle, due to an impact or the like, and is easily reduced in size, when the loading apparatus is not loaded with a liquid container, and also to provide a loading apparatus and a liquid injection apparatus. SOLUTION: An introduction hole 51 is formed at a front end of a supply needle 23 protruded in a holder 20, and a valve mechanism 53 is housed in a flow path 52 communicating with the introduction hole 51 in the supply needle 23. The valve mechanism 53 has: a valve body 56; and a compression spring 57 which energizes the valve body 56 in the front end side direction of the supply needle 23. At the front end of the valve body 56, provided is a shaft-like protrusion 56b which is protruded from the introduction hole 51 in a state of the valve being closed. In the state shown in the drawing, the introduction hole 51 is closed in such a way that a seal member 58 fixed on the front end surface of shaft 56a of the valve body 56 is abutted on the end surface of the flow path 52. When the protrusion 56b is pressed, the valve body 56 is moved, and then the introduction hole 51 is opened. COPYRIGHT: (C)2008,JPO&INPIT |
