Abstract
1345210 Keyboards for printers SINGER CO 21 Sept 1971 [4 Nov 1970] 5337/73 Divided out of 1345209 Heading B6F [Also in Division H1] The disclosure is the same as the main Specification but the invention relates to a keyboard having a push-button key 12 reciprocably mounted in a plate 23 provided with a foam cushioning layer 24 on its upper surface which co-operates with the lower surface of the pushbutton key to cushion its downward movement, the push-button key 12 being provided with means, e.g. a pair of projections 19, which prevent the formation of a vacuum between the bottom surface of the key and the cushioning layer 24. In Figs. 4 and 5 (not shown), the formation of a vacuum is prevented by providing longitudinal grooves in the key stem 16 which extend below the plate 23 when the key is depressed.
