ABSTRACT:
An operating device of an electronic apparatus contains a rotatable operating knob protruding from a panel and stopper means for preventing the rotation of the operating knob. When the power of the electronic apparatus is turned off, the rotation of the operating knob is prevented by a stopper part of the stopper means. When the power of the electronic apparatus is turned on, the rotational operation of the operating knob is can be performed by releasing the stopper part of the stopper means. Therefore, when the power of the electronic apparatus is turned off, that is, when the adjustment of the electronic apparatus is not needed, even when a user inadvertently touches the operating knob, the operating knob does not rotate. Thus, a previously set value is prevented from being inadvertently changed.
