2. Description of the Related Art In a weighing device such as an electromagnetic balance-type electronic balance that accurately measures the load of a measurement object, for example, an electronic balance that displays 0.01 g at a maximum weighing of 6 kg, each part of the weighing mechanism operates even with a small load. In such a case, the weighing pan on which the weighing object is placed may be fanned by the flow of air, making accurate measurement impossible. When the measurement target is, for example, a very small amount of powder, a part of the powder may be scattered even with a relatively gentle air flow.

[0003] For this reason, a device having a weighing chamber formed so as to isolate a weighing object placement portion centered on a weighing dish with glass or the like so as to be isolated from the outside has been used. Recently, a draft shield formed separately from the weighing scale has also been devised, and a configuration has been proposed in which even a weighing scale which does not originally have a weighing chamber is installed, the draft shield covers the weighing object arrangement portion. A conventional example of these configurations is disclosed in Japanese Utility Model Publication No. 54-191.
No. 83 and Japanese Utility Model Publication No. 54-37321.
