Abstract (en)
[origin: US4771143A] The diaphragm keyboard comprises a baseboard from the bottom of which pins (11) project in vertical direction. These pins (11) pass through apertures (22) in an encoding plate (20) and extend beyond the surface thereof, thus presenting spacers for a diaphragm (30). In addition, they serve for retaining and aligning the encoding plate (20).

Diese Stifte ragen durch Öffnungen (22) einer Codierplatte (20) hindurch und über deren Oberfläche hinaus und bilden damit Abstandhalter für eine Membran (30). Zusätzlich dienen sie zur Halterung und Ausrichtung der Codierplatte (20)
