Display unit

Abstract

The invention relates to a display unit in which characters, symbols or pictures are created in matrices composed of lines and columns by the presence or absence of graphic display elements, and the display elements are moved into a visible or invisible position simultaneously in the one direction, such as columns, and subsequently in the other direction, such as lines, by a composing unit activated, for example, electromagnetically, by a data processing unit. The display elements are moved past the composing unit, and when, during this movement, the next axis (column or line) to be set has reached a setting position, an impulse is sent back to the data processing unit releasing the activation of the composing unit. With a transport belt having display elements which are only partially punched out, the display elements can be moved by the composing unit in a way that they will be positioned in front of or behind a separating strip during subsequent rotation of the transport belt. Since the transport belt with its display elements has a contrasting color in relation to the separating strips, the characters created by the arrangement of display elements and separating strips are clearly visible.
