To place. In this state, a vacuum pump (not shown) is driven to depressurize the decompression chamber 301 of the decompression chamber 300 through the decompression port 301a to make a vacuum atmosphere. At this time, the pressure in the sealing chamber 101 of the cell member 100 is also reduced through the injection port 102, so that a vacuum atmosphere is obtained.

[0004] Thereafter, as shown in FIG. 12, the elevation drive means 400 is driven to raise the drive shaft 307 in the vertical direction, and the container 302 for storing the liquid material L is raised in the direction of arrow Y1. Thereby, the entire lower side of the cell member 100 is brought into contact with the liquid material L of the container 302 and is immersed. Thereby, the inlet 102 of the cell member 100 is sealed with the liquid material L in the container 302.

In order to maintain a high degree of decompression, the decompression chamber 300
Sealing means is indispensable for the through hole 305 of the wall body.

In addition, every time the container 302 is moved up and down, the outer peripheral portion of the drive shaft 307 comes into sliding contact with the sealing means of the through hole 305, so that the sliding frequency is high. Therefore, in the prior art shown in FIGS. 11 and 12, the through-hole 305 requires the sliding contact sealing means 500 which has a high sealing ability and induces a special cost that is durable against sliding contact. Disadvantage in terms of

Although the sliding contact sealing means 500 has durability against sliding contact, if the use period is prolonged, there is a possibility that the sliding contact may be damaged due to the sliding contact caused by the elevation of the drive shaft 307. If it is damaged, it is disadvantageous for maintaining a high degree of vacuum and a high degree of vacuum in the vacuum chamber 301. Further, in the prior art shown in FIGS. 11 and 12, the drive shaft 307 moves up and down in the decompression chamber 301 of the decompression chamber 300, so that the elevating space in which the drive shaft 307 moves up and down together with the container 302 storing the liquid material L is reduced. And the size of the decompression chamber 301 and, consequently, the size of the injection device are easily increased.
