2. Description of the Related Art A conventional continuous vacuum vapor deposition apparatus is disclosed, for example, in Japanese Patent Laid-Open No. 62-70576. In such a conventional apparatus, as shown in a side view (A) and a plan view (B) in FIG. 5, an evaporation material 6 is put in a crucible 3 provided in a vacuum chamber 1, and an electron beam 5 is emitted from an electron gun 4 into the evaporation material 6. Is irradiated to melt and evaporate (or sublimate) the evaporation material 6,
The evaporation material6 is vapor-deposited on the vapor deposition substrate 2 such as a steel plate continuously supplied through the guide roll 9.
The inside of the vacuum chamber 1 is maintained at 10-3 to 10-5 torr by a vacuum exhaust device (not shown). As described in the above publication, the width of the crucible 3 is usually made slightly wider than the width of the vapor deposition substrate2 in order to make the film pressure distribution on the vapor deposition substrate2 more uniform. Further, in FIG. 5, the electron beam 5 emitted from the electron gun 4 in a substantially horizontal direction is
A deflection magnetic field (not shown) provided near the upper part of the crucible 3.
Thus, the crucible3 is bent at about 90 ° and is irradiated. In the case of an ion plating device, the structure is the same as the above, but an ionization probe,
Electrons accelerated by a high-frequency antenna or the like (not shown) collide with the evaporation flow 7 to positively ionize the evaporation flow (a part thereof), and form a film on a vapor deposition substrate to which a negative bias voltage is applied. There is. The width of the vapor deposition substrate 2 such as a steel plate needs to be sequentially changed in the production process. For example, it is frequently desired to sequentially change from a wide vapor deposition substrate to a narrow substrate or vice versa. In such a case, in the conventional apparatus and method, in order to efficiently perform vapor deposition, it was necessary to replace the crucible3 with a corresponding predetermined width each time as shown in FIG. 6, for example. In this case, it is necessary to break the vacuum of the vacuum chamber1 and return it to the atmosphere each time, and there is a problem that the vacuuming is required again after the replacement of the crucible3 . As a result, there is a problem that a great amount of time, energy, and labor are wasted in addition to the crucible replacement work, and the operation (vapor deposition) is stopped during this period, resulting in a significant decrease in productivity. Further, as shown in FIG. 5, normally, there is another vacuum chamber 11, 12 of the upstream and respectively in downstream vacuum chamber 1 of the deposition apparatus, these vacuum chambers11 and 12 of the vapordeposition substrate 2 Since it is connected through the passage, the vacuum chamber 1 of the vapor deposition section
When the vacuum of 1 is broken and returned to the atmosphere, the vacuum chambers1 on the upstream side and the downstream side of the vapor deposition section also return to the atmosphere, and there is a problem that the waste of time, energy and labor is further increased. . In order to avoid these problems,
For example, as shown in FIG. 7, it has been proposed and partially used to use a crucible corresponding to the maximum vapor deposition substrate width (hence the crucible having the widest width) as it is even when the vapor deposition substrate has a small width. However, in this case, although the electron beam5 is irradiated only in a range slightly wider than the width of the vapor deposition substrate 2, there is a problem that the heat conduction in the evaporation material6 causes the crucible3 to be heated beyond a necessary range. That is, as shown in FIG., The portion where the electron beam5 is irradiated directly (hatched portion of the right edge), the electron beam5 is not irradiated, heat from the portion where the electron beam5 is irradiated directly Three parts are formed: a part that is melted by heat (diagonally shaded part to the left) and a part that is heated by heat transfer from the part that is being irradiated with the electron beam5 (parts shown by dots). As a result, the heat loss is increased, the efficiency is decreased, and the extra electron beam5 is emitted from the electron gun4 to obtain a sufficient deposition rate.
However, there is a problem that the running cost is significantly increased. Moreover, since the high temperature region of the crucible3 is widened, evaporation occurs from a wide range, and there is a problem that the yield of the evaporation material decreases. In this case marked with a large temperature difference at the central portion of the crucible3 and the both end portions, a large thermal stress on the crucible3 by a difference of thermal expansion amount is generated, it may lead to cracks and breakage, operation on the unstable There was a problem that became a factor. Further, since the central portion of the crucible3 is constantly heated, it is most worn. However, it is necessary to replace the whole crucible at the time of replacement, and the replacement work is difficult and costly. Further, since the crucible body other than the central portion is also heated to an unnecessary range, there is a problem that the rate of wear increases and the life as a whole is shortened. In order to solve the various problems described above, the split crucible13 shown in FIG. 1 has been conventionally used.
