摘要： A motion mechanism in a type printer, wherein the axial displacement of a type drum relative to a printing hammer for setting the required type in position opposite the hammer, and the axial movement of both hammer and type drum for obtaining a new printing position on the sheet, is effected by means of a cord system which consists of a single cord, a type of endless chain. The cord runs over pulleys arranged at each end of the line to be printed, such that the cord is divided into four cord parts extending substantially parallel to the line on the sheet, one cord part supporting the hammer, and one supporting the type drum. At one side, two pulleys are arranged in spaced relationship on a plate which is mounted pivotally about an axis lying intermediate the rotational axes for the two pulleys. Furthermore the cord co-operates with a driving motor operating on that part of the cord which leads to the hammer. Setting of the hammer to a new printing position on the sheet is then effected by displacing the whole cord in its length direcion by means of the driving motor, whereby the hammer and the type drum will move equal distances. Setting of the type drum to a posion with a new type opposite the hammer is made by pivoting the mounting plate for the pulleys, whereby the type drum only is moved, while the hammer is held fixed.
