SKRIVMASKIN ELLER LIKNANDE MASKIN

摘要

A typewriter or similar machine having a platen turnable by means of a ratchet and a line spacing wheel and a carriage movable along the platen by means of a pulling means, on which a typing element or push button is disposed. In accordance with the invention a so-called lift-rotation motor is used for turning the platen, for line spacing and for moving the carriage. Its turning movement is transferred to the carriage by a pulling means. The axial movement of the motors causes the pivoting of a ratchet support on which the spacing ratchet is disposed which turns the platen by means of a toothed spacing wheel. In this way no additional motor for one of the two functions is required. The lift and rotary movement of the motor can take place temporally superimposed. In this way no time delays occur in the course of operation of the typewriter or of a printer.
