ABSTRACT:
The typewriter comprises a character carrying daisywheel having flexible petals which is carried by a carriage that is movable transversely with respect to the platen roller. Mounted on the carriage are a motor for moving the carriage, a motor for character selection, a print hammer, a cartridge for the typing ribbon, a correction ribbon and a drive unit for advancing the typing ribbon and raising and advancing the correction ribbon. The structure of the hammer and the arrangement of the typing ribbon and the character carrying daisywheel are such that typing and reading of the line of print are possible without it being necessary for the typing ribbon to be raised. The carriage is displaced in the two directions from the current position to an intermediate position to the left of the desired position. The carriage is then positioned precisely by a tooth-type setting means after a undirectional displacement of the displacement motor.
