Abstract: A typewriter or similar machine with a print wheel disposed on a shaft drivable by a motor, the characters of which are printed by means of a hammer. In accordance with the invention, use of a separate print magnet is to be omitted. This is made possible by the use of a lift-rotation motor. Its rotational movement is used for the rotational positioning of the print wheel, while the axial movement of the motor shaft is transferred to a print hammer pivotably disposed on the carriage. Determination of the engagement point of the motor shaft with the print hammer makes possible the optimum determination of the movement cycle of the print hammer as well as its print force. Thus the space above the motor for the print wheel, otherwise required for a print magnet, can be used for other purposes. Additionally there is a reduction of the masses which are required to be moved along the platen.
