<p>A navigation device has a joystick (2) capable of three movements, inclination (arrows 22a to 22h) in predetermined directions, rotation (arrows 21a, 21b) around an axis (20), and depression (arrow 23) along the axis (20). Therefore multiple navigation functions can be assigned to the operations of the joystick (2), and the number of switches of the remote controller and operation panel unit can be small compared with the prior art.</p> |
