2. Description of the Related Art In recent years, technological innovations in video equipment, digital cameras, thermal imaging cameras, and other photographing instruments have been remarkable, and small cameras have been mass-produced and can be obtained at low cost.
Also, a large-capacity storage medium for storing images is available at low cost.
For this reason, in the field of environmental test equipment, there is a demand that the state of the test room be photographed by a camera and monitored externally, or the state of the test room be continuously photographed and recorded.

However, the test room of the environmental test apparatus may be in a high-temperature, high-humidity environment or a low-temperature environment, and these can be said to be extremely severe environments for the camera.
Therefore, if the camera is installed in the test room for the purpose of photographing the state of the DUT, the camera may break down in a short period of time.

Therefore, it is conceivable to install a camera outside the environmental test apparatus and take a picture of the test room from the window of the environmental test apparatus.
As one of the measures, it is conceivable to install a commercially available camera tripod outside the environmental test apparatus, fix the camera at a hollow height with the camera tripod, and photograph the test room from the window. In addition, a method of fixing the camera to the window glass of the test room with a suction cup or the like can be considered.

The former method using a tripod requires a large space for installing a tripod in front of the environmental test apparatus. Therefore, if a place for installing a tripod cannot be secured in front of the environmental test apparatus, this measure cannot be adopted.
Many of the windows are provided on the door of the environmental test equipment. Therefore, if a tripod is installed near the window, the tripod may hinder the opening and closing of the door in some cases.
When a tripod is used, the tripod itself occupies a large space. For this reason, it may be difficult to secure a place for installing lighting for illuminating the test room.

Further, since the camera tripod is a device for temporarily placing the camera and is not fixed to the floor, the camera tripod may be moved by hitting an object. On the other hand, since environmental tests may be performed over a long period of time, it may be necessary to keep the camera in the same position and in the same posture, and a camera tripod is not suitable as a camera fixing means to meet this requirement It is.
In addition, when photographing the test room using a camera tripod, it is difficult to focus the camera on the photographing target.

  As a measure for fixing the camera with a suction cup or the like, there is a risk that the suction cup will come off and the camera will fall. Further, the window glass of the environmental test apparatus may be heated or cooled at a high or low temperature, and the suction cup may be softened or hardened, and the suction force may not be maintained.

  Some apparatuses having a chamber, such as a heat treatment apparatus, also have a window, and there is a demand to take a picture of the inside of the chamber with a camera through the window. The same problem as in the case of the environmental test device occurs when photographing the inside of the chamber.
