A printing device (18) intended for marking of objects (1) with a so-called bar code (47) comprising combinations of light and dark bars forming together an optically readable symbol. The printing device comprises a package of a plurality of thin lamellae (20) arranged parallelly in close proximity to each other. The lamellae are displaceable in said planes by means of current pulse operated actuating means (26) when being guided, in order to change the reciprocal positions of the lamellae end edges and to set the desired printing pattern at one side of the lamella package. Moreover, the printing device includes operating means (38), which are arranged to fix the lamellae reciprocally in the set position and to impart a reciprocating movement to the lamella package. |
