Abstract (en)
A matrix printer which has a printing head including a line of printing needles. A plate (22) is disposed over the end of the printing head (4) and is formed to constitute a plurality of leaf springs (8) each of which carries at one side an anvil (9) aligned with a respective printing needle and at its other side a stud (10) which has an impact area smaller than or different to the impact area of the respective printing needle. Striking movement of the printing needle deflects the spring to cause the respective stud to mark the printing sheet. The arrangement facilitates the production of different styles of characters, the production of finer detail in characters and provides printing members which are more easily replaceable than printing needles.
