Abstract
1,175,174. Keyboards. KIENZLE APPARATE G.m.b.H. 15 March, 1968 [18 March, 1967], No. 12689/68. Heading G4H. Operation of a key 53, Fig. 3, causes temporary raising of magnetic pins 93-96 through holes in plates 101-103 carrying a primary printed circuit conductor P 1 -P 4 and secondary printed circuit conductors S 1 -S 8 , a flag 122 passing between light source 124 and photo-cell 125 providing an energizing pulse for primary P 1 -P 4 . The arrangement of conductors S 1 – S 8 is such as to give a combination of outputs unique to the associated key 53. A latch 86
