Abstract
A printing head of the type in which the tips of the needles are guided in two parallel rows by a pair of matrices disposed side by side comprises a support which carries a first matrix. The support is fixed to a printing body. The second matrix is carried by a support movable on the printing body so as to move the second matrix in parallel to the first from a position in which the tips of the needles in the two rows are at the same heights, for high-speed printing to the position in which the tips of the needles in one row are located at the heights of the spaces between the tips of the needles in the other row, for high definition printing. The movable support is connected to the printing body by a parallelogram structure in which two parallel sides are constituted by the support and the printing body while two other sides are formed by resiliently-deformable members. A pre-loaded, resilient biasing member maintains the movable support against a first abutment. An electromagnetic actuator is provided, which, when operated, moves the movable support into contact with a second abutment.
