However, the metal case has a problem of rust, and in particular, the metal case provided with the opening / closing mechanism of the cover opens the lid to open the electronic case inside when the hinge part rusts. Difficult to check and adjust the equipment. Moreover,
Since the metal case is heavy, it is inconvenient to handle, and it may be necessary to reinforce the columns and wall surfaces to be attached. On the other hand, in order to eliminate the disadvantages of these metal cases, it is possible to form the entire case with a synthetic resin material, but in order to shield the circuit board, it is necessary to wrap the circuit board with a metal plate material to form a unit. Therefore, the number of manufacturing processes is increased, and maintenance of the circuit board becomes difficult.
