Abstract

An interposer mechanism is used with a row of print hammers to enable impact printing of characters from a revolving type band at either of two print densities. As seen in Fig. 1, the interposer mechanism comprises interposer elements 10 and 11 positioned between hammer elements (not shown) and a rotating type band 12 separated by continuous paper forms 13 and ink ribbon 14. Interposer element 10 is a comblike structure comprising uniformly spaced flexure elements 15 extending from rigid mounting bar 16 which is stationary. Flexure elements 15 terminate in an impact head 15a having an impact face width spanning a single print position.
