Abstract
Apparatus for generating and displaying moving pictures in which a combination of a number of locally displaceable picture elements have positions that are variable and/or selectable by a number of adjustable outer or final control elements. At least part of individual final control elements have associated with them an inner control element. The position of the final control elements is variable in response to the action of the control elements, and these inner control elements are arranged on a movable inner control element carrier. The control elements constitute mechanical information storages in which the information has a total of at least two mechanical states and can be transmitted by mechanical contact to the associated final control elements, and hence to the picture elements. The information of the inner control elements is made variable by moving the control element carrier.
