2. Description of the Related Art Conventional FPU equipment is an FPU equipment consisting of a pan head integrally fixed on a folding tripod and an FPU head held and fixed on the pan head, such as on the roof or roof of a building. Was installed and used. Although it was not a big problem when relaying for a short period under a very normal environment, when relaying for a long time under severe conditions (eg volcanic eruption relay) (current Unzen・ In the case of eruption-related relay of Mt. Fugen), each element of tripod, platform and head that compose the FPU equipment is damaged, and it is unavoidable to replace it, or even if it is not replaced again. It was in an unusable state.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention The conventional drawbacks will be described by taking the FPU equipment currently used at Unzen and Fugendake as an example. The tripod was very rusty, and the moving parts were clogged with volcanic ash.
It is difficult to fold and cannot be reused.
In addition, the legs often pierce the roof during installation.

Like a tripod, the platform has severe rusting and has a complicated structure, so that it cannot be adjusted due to rusting. Further, since the tightening mechanism is complicated and is not installed for a long period of time, the direction is often deviated by a strong wind such as a typhoon.

In order to protect the head from wind and rain, the head was covered with a vinyl sheet and wound and fixed with rope or vinyl tape. However, depending on how the vinyl sheet is covered, waterproofing measures may be insufficient, or conversely I was trying to collect rainwater. Further, in the hot summer in the midsummer, the temperature inside the vinyl sheet becomes high, which leads to a head failure. In addition, it takes a lot of time to install the vinyl sheet, and there are large differences among individuals, which is a serious problem that is greatly related to the reliability of the head and thus the safety of broadcasting.

The present invention solves the above-mentioned drawbacks of the prior art,
F that can be used for long-term relay under adverse conditions
It is an object of the present invention to provide a PU device that can be easily reused even when used in another place after the relay is completed.
