摘要： An electromagnet and a permanent magnet are arranged in parallel between first and second pole pieces having a metallic spring tine coupled to the first pole piece and disposed to be attracted to the second pole piece by the magnetic field of the permanent magnet. A sensing coil is positioned to sense magnetic flux changes resulting from changes in position of the metallic spring tine. In operation the spring tine is displaced to the second pole piece and captured at a home position by field energy from the permanent magnet. When there is a demand for printing, the electromagnet is energized in a first polarity such that its reluctance to the field of the permanent magnet is minimized and the flux from the permanent magnet is attracted to pass through the core of the electromagnet thereby nullifying the traction between the spring tine and the second pole piece and the spring tine is released. Potential energy stored in the tine by the displacement of the tine is transformed to kinetic energy and the tine moves swiftly to effect a print impact. Following impact, the electromagnet is energized in a second polarity such that its reluctance to the field of the permanent magnet is of the spring tine. Flux movements detected by the sensing coil are utilized in a closed loop system to regulate amplitude and polarity of the field of the electromagnet for home, release and capture cycles of the apparatus.

摘要： An impact hammer assembly, suitable for high speed MICR printing, is disclosed. The impact hammer assembly comprises an impact hammer having first and second flanged portions respectively positioned at first and second ends along a first longitudinal surface of the impact hammer and a hammer face positioned at the second end of the hammer on a second longitudinal surface opposite from the first longitudinal surface. The hammer is pivotally mounted at a pivot between the first and second flanged portions for movement between a rest position and a print position. A first electromagnetic coil positioned adjacent to the first flanged portion is energized by a first pulse from a control circuit to impel the hammer face toward the print position. A second electromagnetic coil positioned adjacent to the second flanged portion is energized by a second pulse from the control circuit to cause a fast return of the hammer to the rest position. A spring is connected to the hammer at a point between the pivot and the second flanged portion to provide damping of oscillations of the hammer upon the return of the hammer to the rest position.

摘要： A magnetic field is applied to a recording element by energization of an electromagnet or by a permanent magnet to a saturation point of the element material to cause the recording element to move in relation to the electromagnet or to the permanent magnet when the magnetic field is reversed. The polarity opposes or reverses the field to enable a controlled repulsion force and causes the recording element to move in an opposite direction. Magnetic hysteresis is thus utilized in the repulsion and attraction of such an element in both directions of movement.

摘要： A print hammer mechanism for use in an impact printer such as a band printer or other printer which has printing elements which are impacted to make impressions on paper or other record medium. The hammer of the mechanism is impacted by dual armatures in forward motion toward the paper and return motion away from the paper so that the hammer is positively driven and does not depend upon the bounce back of the hammer from the paper or need a return spring on the hammer. This reduces the time for each hammer stroke and increases printing speed (characters per second). The armatures are normally decoupled from the hammmer and strike the hammer only after accelerating sufficiently to transfer sufficient speed to the hammer upon impact therewith. Springs are used to bias the hammer to a home position in the return direction and to maintain the armatures against a stop spaced from the hammer so that the armatures are normally decoupled from the hammer. The spring forces are light; forward and return hammer drive being provided by the armatures. A magnetic field structure for independently actuating each armature can be used for actuating the hammer in timed relationship with printing operations.

摘要： The specification describes a low reluctance magnetic circuit for a dot matrix line printer for retaining hammersprings by the magnetic circuit having pairs of pole pieces formed of magnetically conductive sheets having a space for receipt of a permanent magnet. A coil is wrapped around a portion of each of the pole pieces between the magnet and the ends to provide a reverse magnetic field to the magnetic field provided by the permanent magnet. A magnetic shunt is established between the pole pieces to provide a greater magnetic effect. The pole pieces are sized and plated at the ends, with a spaced wear bar between them to provide improved performance and longer wear.
