Abstract

1326644 Selective printing CIBA-GEIGY AG 30 Dec 1970 [30 Dec 1969] 61886/70 Heading B6F A selective printer comprises type members 27 urged against a platen 20 by sliding hammers ], the hammers being propelled towards the type member 27 by coil springs 7 when latches 14 are released thereform by electromagnets 15, the hammers being collectively returned to cocked position by a common reset device 13, 13a. Hammer rebound is prevented by the latch 14 engaging a shoulder (30, Figs. 5-7) when the hammer bounces off the type member 27 and platen 20 after impression. The type members 27 are mounted on leaf springs 28 on a reciprocating carriage 23.
