Abstract: A basic movement may be imparted selectively to each movable component (A, D, RD, RG, V) in either of two opposite directions. For this purpose, an adjustment assembly comprises a control device (20) common to all the components to be adjusted and including component position adjusting means. The adjusting means comprise means (38) for selecting a component to be adjusted and a basic movement thereof, as well as means (40, 42) for executing the selected movement in a selected direction. The adjustment assembly further comprises means (60) for displaying data on the selected component and basic movement, and means (68) for switching the control device (20) to a movable component position adjustment mode or to a control mode for controlling at least one other non-movable means such as a radio-cassette player.
