ABSTRACT:
In a printing device, printing type rings are mounted on a rotatable, grooved shaft. Each ring has associated therewith a pawl and a selecting mechanism for engaging the pawl with a selected groove on the printing type ring whereby a selected character on the ring may be brought to an inking position and then to a printing position. Retraction of the pawl by said printing mechanism disengages the pawl and allows the ring to reach a rest or stand-by position.
By the use of the retractable pawl a printing device is provided in which only those rings which are about to be used for printing are rotated, and the load on the inking mechanism is greatly decreased. The printing device may therefore be decreased in size and in energy consumption and the wear on the various members of said device is greatly decreased.
