Abstract
The disclosure concerns a bar code printing device for use with the printing head of a portable label printing and applying machine, or the like. A plurality of juxtaposed index rings are selectively turned by a selecting member and each index ring turns a corresponding meshing bar code type ring into a selected printing position. The type rings are also juxtaposed. A rotary member is also turned by the selecting member for causing straight line reciprocating movement of an actuating member across the axis of the rotary member and this in turn moves a thrust member in the axial direction of the type rings. The thrust member is moved to bias the type rings during the printing operation so that the type rings are forced into close contact. The thrust member is also moved to permit the type rings to be left as they are, during the imprintable type selecting operation, so that the type rings are spaced by gaps which facilitate the selective rotation of the rings by the selecting member.
