ABSTRACT:
A selector system for a typewriter of the single type carrier kind, in which a series of stop members are selectively positionable in order to cooperate with two selector levers in such a manner as to effect the variable displacement of the type carrier for the selection of the character which is to be printed. A control member releases the selector levers for their operation by driving forces and comprises a cyclic resetting member which returns the selector levers to their position of rest against the action of the driving forces on completion of the typing of the character selected. A shift device for the type carrier comprises a cyclically operating drive mechanism adapted to operate a member kinematically connected to the type carrier for the selection of one of the two zones in which the characters are distributed.
