    摘要： A shuttle mechanism of a printer apparatus wherein a balance shuttle unit is arranged on the opposite side of the print head in a print shuttle unit, for instance, on the under side of said print shuttle unit, so that the center of the gravity of the print shuttle unit is made to become close to that of the balance shuttle unit. Common components such as the magnet, yoke, guide member may be employed in both the shuttle units.

    摘要： A base for operative association with an operating mechanism sensitive to horizontal vibration, such as an ink jet printer, supports a horizontal document feeder plate and associated drive operative to advance documents in sequential fashion from a stack toward the operating mechanism. A drive linkage interconnects a rotatable drive shaft to the feeder plate to effect horizontal reciprocating movement thereof. A counterweight is associated with the drive so as to substantially offset or nullify horizontal inertia forces imparted to the base by the feeder plate whereby to minimize horizontal vibration of the base. In an embodiment utilized for intermittent feeding of documents to the operating mechanism, a balance arm and associated counterweight cooperate with the feeder plate to offset horizontal inertia forces imparted to the base, and also minimize start-up torque required to initiate reciprocating movement of the feeder plate after stoppage.

    摘要： An arrangement for bidirectionally driving a hammer bank shuttle assembly along a linear path in a line printer includes an opposite pair of circular, rotatable elements having an elongated shuttle assembly mounting element and an elongated counterbalancing element extending between the pair of rotatable elements on the opposite sides thereof. Pole pieces and a magnet disposed between and adjacent the shuttle assembly mounting element and the counterbalancing element provide magnetic flux which flows through portions of the opposite elements to attract and maintain the elements in contact with the opposite rotatable elements. A pair of serially coupled coils mounted on the counterbalancing element and disposed within the air gaps formed by the pole pieces and the magnet are energized by a cyclically varying signal to bidirectionally drive the shuttle assembly mounting element and its included hammer bank shuttle assembly along the linear path as the counterbalancing element is caused to reciprocate between opposite limits of movement defined by an opposite pair of resilient elements in the path of movement of the counterbalancing element. In an alternative embodiment the coils are disposed between the counterbalancing element and the shuttle assembly mounting element so as to form air gaps with and magnetically interact with a first pair of magnets mounted in spaced-apart relation along the length of the counterbalancing element and a second pair of magnets mounted in spaced-apart relation along the length of the shuttle assembly mounting element.

    摘要： A carrier is suspended and moves on two shafts. The carrier includes a plurality of sealed roller bearings which form openings approximately equal to the dimensions of the shaft. One or more of the bearings is mounted on a leaf spring to provide a predetermined contact pressure between the bearings and the shaft. In addition, damping elements may be substituted for one or more of the sealed roller bearings to minimize interference from vibrations.
