ABSTRACT:
An operating device for controlling a display screen, which includes a rotatable operating member of cylindrical shape, and a slidable operating member having a cylindrical tip portion located above an upper end of the rotatable operating member. The diameter of an upper surface of the slidable operating member cylindrical tip portion is reduced relative to a diameter of a lower surface of the cylindrical tip portion, and the diameter of the lower surface of the slidable operating member cylindrical tip portion is equal to or less than a diameter of an upper surface of the rotatable operating member. An operating device is provided which prevents a misoperation in slide operation and rotation operation and improves operability.
