Abstract

Device for changing the signs on a typewriter with a type element (head) arranged on a carriage and which, for printing, performs at least rotary movements controlled by cams, which, by means of a rack element with two separate teeth, of which, each time, only one meshes with the pinion, are transmitted to the shaft of the type element, characterized by a gear rack switching mechanism with a rocker arm connected to the mentioned gear element and supported by tilting to adopt one of two alternative positions, by at least one actuation of the rack switching mechanism, which acts cyclically and only at the beginning of a cycle, as well as by two transmission elements that are arranged between the mentioned actuator and the rocker arm for commutation or change thereof.
