To ensure waterproofing property and sinklessness of an electronic device even if dropped accidentally in water. There is provided the electronic device equipped with a device main body 1 with a waterproofing structure in which a downside 6 of a main body case 2 is formed in a ship bottom-shape, an upper side 7 of the main body case 2 is tarbularly formed so as to protrude toward more outer peripheral side than the downside 6 and further an open space 8 limited for allowing the device main body 1 to float is formed inside the main body case 2. Accordingly, even if the device main body 1 is dropped accidentally in water such as in that of a bathtub, the device main body 1 can float on a surface of the water by means of the space 8 inside the main body case 2. In this case, it occurs easily that the downside 6 of the main body case 2 is positioned underneath the water and the upper side 7 thereof above the water, so that the device main body 1 can float on the water surface stably in that state. Consequently, water pressure applied to the device main body 1 can be reduced considerably and so the waterproofing property can be ensured by a simple waterproofing structure without adopting a high pressure waterproofing structure having high water-tightness.

The invention provides an armor type shield and a machine tool. Waterproof fabric is connected between all internal supports of the armor type shield, so that the waterproof fabric covers the inner side of the armor type shield, and elastic connecting devices and limiting strips between the internal supports of the armor type shield are sealed between the waterproof fabric and scale. By means of the elastic connecting devices and the limiting strips, while all levels of structures in the armor type shield are linked, the intervals between the scale of the armor type shield are automatically compressed, and first-level waterproofing is achieved. The waterproof fabric in the armor type shield provides additional waterproofing, thus, the waterproof effect is better, and the situation that theshield fails overall as any level of waterproofing fails can be avoided. When the armor type shield stretches and is compressed, acting force borne by a flexible material originally is transferred tothe elastic connecting devices and the limiting strips, traction abrasion of the waterproof fabric can be effectively avoided, and the service life of the armor type shield is prolonged.
