摘要： In a differential lever actuator comprising transmission members (41, 42) for differentially transmitting oppositely sensed angular displacements from first and second weight points (P1, P3) of first and second lever members (31, 32) to first and second predetermined points (P2, P4) of a differential lever member (41), a distance between midpoints (S, T) between the first weight and predetermined points and between the second weight and predetermined points is kept constant irrespective of the angular displacements. Preferably, at least one transmission member should be perpendicular to a line passing through the related weight point and a fulcrum point (Q or R) of the associated one of the first and second lever members. When carried by the differential lever member for print of a dot, a rod should preferably have an axis passing through a point of intersection of the transmission members. Alternatively, the differential lever member should have a center of a rotational component of the distance (ST) at a point of percussion related to a reaction resulting from print of the dot. As a further alternative, at least one transmission member should be thicker than 0.05 times a length between the related weight and predetermined points.

摘要： In needle printing apparatus with a plurality of parallel working printing needles which are each provided with a selectively controllable blocking device and a yielding stroke equalizing element, in order to arrive at an extraordinarily compact construction each printing needle and its stroke equalizing element is formed in one elongated piece of springy material. Preferably all of the printing needles and their stroke equalizing devices are made from one suitable spring plate, formed by etching, stamping, milling or the like, in the shape of a comb whereof each tooth comprises an actual printing needle, and the stroke equalizing element has a zigzag shape. The printing needle and the yielding equalizing element are thus no thicker than the thickness of the spring plate. Over this thin spring plate one can then arrange corresponding blocking elements, likewise formed in comb shape. Each individual tooth of this blocking element comb is formed as a piezoelectric bending transducer which can freely engage between the printing needles and on which there is an abutment that engages an abutment on the shaft of the respective printing needle to arrest the latter against forward motion.

摘要： A plurality of printing needles forming an array are mounted in a printing head and are periodically driven to impact a printing ribbon onto a recording medium. The printing head contains a brake for each needle so that selected needles can be prevented from striking the printing ribbon allowing the formation of a desired character matrix pattern on the recording medium. Each brake may be driven by a piezoelectric element.
