A control unit indicates a cursor on a screen of an indication unit according to operation data sent from an operation unit based on user's operation of an operation knob. The control unit implements enlarging indication of a screen region corresponding to a selection item image indicated on the screen of the indication unit. When the control unit implements contracting indication to return an enlarged screen region subsequent to the enlarging indication, the control unit indicates contraction of the screen region in a visually recognizable form and indicates the cursor to follow the screen region. The operation unit further causes a driving force generation unit to generate a driving force to move the operation knob correspondingly to the position of the cursor, according to information on the position of the cursor sent from the control unit.
