A space is formed between the outer circumferential surface and the outer circumferential surface.

It goes without saying that the casing according to the present invention can also be used as a casing for audio equipment such as a stereo or optical equipment such as a television camera.

As explained above, according to this invention, the casing has a double structure consisting of the casing body and a cover that is detachable from the casing body, and when it is installed on the installation panel, it protrudes from the outer periphery of the casing body. It can be installed safely and securely using the step on the back of the flange provided, and when used as a portapull type, the mounting screw holes etc. are covered by the above cover, so installation on the above panel can be used as a type or as a portapull type. This has the effect that it can be used in common with other applications without any problems.

That is, when installing the device on the panel, the flange can reliably support the device, and the flange can cover the gap between the installation opening of the panel and the main body of the casing to prevent dust and other particles from entering the inside of the panel. In addition, when used as a portable type, the mounting screw holes or mounting brackets used when installing the panel are covered with a cover to prevent dust from entering the mounting screw holes and during use. It has the effect of eliminating danger.

Furthermore, according to this invention, as mentioned above, when the panel is installed, the gap between the installation opening of the panel and the casing body is hidden by the front flange, so there is no risk of spoiling the appearance from the front of the panel. Even when the portapull type is used, the outer periphery of the front flange and the outer periphery of the outer casing are continuous with almost no difference in level, and there is no possibility that the exterior appearance will be impaired when the portapull type is used.

Further, according to this invention, the cover has a spacing retaining portion projecting in the shape of a flange on the inner periphery of the front and rear edges of the cover, which is in contact with the outer circumferential surface of the housing body, and the cover is formed between the front and rear spacing retaining portions. Since it is attached to the outer periphery of the casing body with a gap between the inner peripheral surface and the outer periphery of the casing body, mechanical shocks from the outside are not directly transmitted to the casing body. The electronic components inside the housing will not be damaged, and because of the air space created by the above-mentioned spacing, the heat from the external heat source will not directly affect the electronic components inside the housing. It has excellent practical effects.
