In a vacuum chamber a consisting of an upper chamber `` and a lower chamber (deposition chamber) g separated by a partition plate, a coiled film b is unwound from an unwinding glc, and is transferred from a crucible j in the lower chamber g. The aluminum vapor generated from the nuclear power plant is deposited on one cooling roll (deposition roll) and wound on a winder e. When the deposition of the first coil is completed, the vacuum chamber d is opened to the atmosphere, and a new FILNO, which has been wound into a coil, is After replacing B, put it on the pump again.
Perform the work of evacuation and vapor deposition using ffi. The aluminum in crucible j consumes about 1 kg at a time, so there is no need to continuously supply it, but when opening it to the atmosphere, to prevent crucible j from breaking, it is discharged each time and the inside of crucible j is After cleaning, load new aluminum. As described above, the vapor deposition work using the vacuum trace deposition device shown in Fig. 3 is a punching work that repeats mounting of the film, cleaning of the crucible, loading of new vapor deposition material, evacuation, heating, running, vapor deposition, and opening to the atmosphere. It was extremely inefficient.

[Effects of the Invention] According to the present invention, it is possible to continuously supply a deposition material to a deposition material container in a deposition chamber for a long time without opening the deposition chamber and therefore without increasing the pressure inside the deposition chamber. can. Moreover, since the high-temperature vapor deposition material can be taken out from the vapor deposition material container in a vacuum at the end of the inspection, it is possible to prevent the vapor deposition material container from burning out.
