Abstract (en)
[origin: US4278357A] A daisy wheel spring disc utilized in conjunction with a daisy wheel print element to control impression. Both the spring disc and the print element have radially extending petals. The print element petals carry a character adjacent their outer extremity. A spring disc petal is associated with each print element petal for which impression is to be controlled. The spring disc petals vary in length relative to the print element petals. The lengths of the spring disc petals depend upon whether the character on the associated print wheel petal has a large or small print surface area. During printing, the spring disc is positioned on the printing side of the print element. When a print element petal is driven out of the plane of the remaining print element petals during printing of a character, the associated spring disc petal will be contacted and will absorb a portion of the energy imparted to the print element petal.

Typenscheibendrucker, bei dem der Typenscheibe (1) eine Federscheibe (5) gleicher Teilung zugeordnet ist. Beim Anschlag einer auf dem Finger (2-1, 2-2, 2-3) der Typenscheibe (1) befindlichen Type (3-1,3-2,3-3) wird dieser Finger gegen die Federkraft des ihm zugeordneten Fingern (5-1, 5-2 5-3) der Federscheibe (5) bewegt. Die Finger (5-1,5-2,5-3) der Federscheibe (5) haben eine unterschiedliche Länge, so daß für die verschiedenen Zeichen gleiche Abdruckstärken erzielt werden.
