<P>PROBLEM TO BE SOLVED: To lessen load of a communication function of a control computer without fault in a high-frequency shielded room. Ž<P>SOLUTION: This electric apparatus such as a diagnostic magnetic resonance apparatus includes: a first component arranged inside the high-frequency shielded room; a second component arranged outside the high-frequency shielded room; and the control computer connected to the components through control lines. The control lines are constructed as a serial sensor/actuator bus. The sensor/actuator bus has a first bus portion having electrical bus lines, and a second bus portion has optical bus lines. The optical bus lines are put in the connecting state in the high-frequency shielded room and are connected therein to the first component. The first bus portion is connected to the second bus portion through an electro-optical interface. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
