Description

Die Erfindung betrifft eine Abdeckvorrichtung mit verschiebbaren Maskenbändern für Kopier- und Vergrößerungsgeräte; sie besteht darin, daß die zwei rechtwinklig zueinander stehenden Maskenbänder des einen Paares auf je -einer längs beweglichen Einstellschiene verschiebbar angeordnet sind und daß diese beiden Sühienen durch ein gem@einsames Getriebe gleichsinnig verstellbar und mit den beiden anderen, einen starren Winkel bildenden Maskenbändern derart gekuppelt sind, daß sich dieser Winkel bei Verschiebung der Einstellschienen in diagonaler Richtung und gegenläufig zu den beiden ersterwähnten Maskenbändern bewegt.The invention relates to a covering device with displaceable mask straps for copiers and enlargers; it consists in the two being at right angles mask bands of one pair standing to one another on each -one longitudinally movable Adjusting rails are slidably arranged and that these two rails through a common gear can be adjusted in the same direction and with the other two, one Rigid angle forming mask bands are coupled so that this angle when moving the adjustment rails in a diagonal direction and in the opposite direction moved the first two masking tapes.

Die Figur zeigt schematisch ein Ausführungsbeispiel.The figure shows schematically an embodiment.

Die zwei rechtwinklig zueinander stehenden Maskenbänder b des einen Paares sind auf je einer in dem Trägerrahmen längs beweglichen Einstellschiene c verschiebbar angeordnet. Diese beiden Schienen c sind durch ein gemeinsames Getriebe d gleichsinnig verstellbar und mit den beiden anderen., einen starren Winkel bildenden Maskenhänder na derart gekuppelt, daß sich dieser Winkel bei Verschiebung der Einstellschienen c in diagonaler Richtung und gegenläufig zu den beiden ersten Maskenbändern b bewegt.The two mask bands b of one another at right angles to one another Pairs are each on a longitudinally movable adjustment rail c in the support frame arranged displaceably. These two rails c are through a common gear d adjustable in the same direction and with the other two., forming a rigid angle Mask handers na coupled in such a way that this angle changes when the adjustment rails are moved c moved in a diagonal direction and in the opposite direction to the first two mask bands b.

Durch die Erfindung wird der Vorteil erzielt, daß alle vier Mashenb,änder mit !einem Griff gleichzeitig und gleichmäßig verstellt werden können.The invention has the advantage that all four Mashenb, change can be adjusted simultaneously and evenly with one handle.
