A top cover hinge is combined with a spring clutch-type cover support and a membrane cover interlock switch. The cover support supports the cover in the open up position. The cover hinge is made of spring material so that it can reliably actuate the membrane switch without requiring adjustment. As shown in the figure, a top cover 11 is mounted to the movable part 13 of the hinge. The fixed portion 15 of the hinge is mounted to the body of the machine using screws 17. A membrane switch 19 is fastened to a back portion of the hinge, as shown in the drawing, and electrical contacts 21 are brought out for connection to the electronics.
