摘要： A printing mechanism for use in an impact printing system primarily intended for the transfer of a dry film impression onto an image carrying tape. The mechanism includes a hammer (130), and an anvil (126). The hammer is actuated by lever arm (164) which is in turn actuated by eccentric cam (194). The degree of impression is controlled by an eccentric bearing (211) and the hammer can be adjusted for exact parallel engagement by moving plate (142) which pivots the hammer. The system is actuated by a geared drive train which rotates the eccentric cam (194) and causes the hammer to reciprocate.

摘要： Magnetische Betätigungsvorrichtung, bei der das Betätigungselement (12; 48, 58) durch einen einseitig gerichteten magnetischen Fluß in gespannter Position gehalten wird, dessen Flußdichte in seiner Amplitude sich zyklisch mit der Zeit ändert und durch selektive Erregung einer Kompensationswicklung (30; 61) ausgelöst wird, wodurch dem die Haltewirkung auslösenden Fluß dann entgegengewirkt wird, wenn die Flußdichte geringer ist als ihr Maximalwert. Der Maximalwert des Halteflusses kann dabei so hoch gewählt werden, daß diese Flußdichte ausreicht, das ausgelöste Betätigungselement (12; 48, 58) in seine gespannte Position zurückzuziehen.

摘要： An impact printer with a hammerbank having print hammers retained by a permanent magnet (82) for impacting a print ribbon, and a mechanical driver for moving the hammerbank across print media. First and second coils (98, 100) for each hammer are wrapped around first and second pole pieces (84, 86), one of which is asymmetrical to the other pole piece. One of the pole pieces (84) can have a generally elongated longitudinal form with the coil (98) wound around the longitudinal form. The other (86) can have a generally arcuate form, with the coil (100) wrapped on a portion between the ends thereof. The coil (100) wrapped around the arcuately formed pole piece (86) is thicker than the coil (98) wrapped along the longitudinal pole piece (84). The result is to provide pole pieces and coils for an impact printer having differing spatial relationships that can be staggered, or formed asymmetrically for more compact coil and pole piece placement to improve printer efficiency.

摘要： The specification describes a low reluctance magnetic circuit for a dot matrix line printer for retaining hammersprings (16) by the magnetic circuit having pairs of pole pieces (44) formed of magnetically conductive sheets having a space for receipt of a permanent magnet (52). A coil (94,96) is wrapped around a portion of each of the pole pieces (44) between the magnet and the ends to provide a reverse magnetic field to the magnetic field provided by the permanent magnet (52). A magnetic shunt (54) is established between the pole pieces (44) to provide a greater magnetic effect. The pole pieces (44) are sized and plated at the ends, with a spaced wear bar (70) between them to provide improved performance and longer wear.
