摘要： A line printer having a hammerbank with hammers that are held by a permanent magnet and released by electrically driven coils. The temperature of the coils is determined by the relative resistance of the coils to provide an output equivalent to the temperature of said coils. The resistance is determined as a function of the current through the coils or voltage of the coils which is converted from an analog to a digital value. The attendant method of determining temperature of the coils in the hammerbank is by comparing a pre-established current or voltage value based upon a pre-established temperature of the coil with the current passing through the coil during operation of the hammerbank. The comparison of the current passing through the coil during operation with the pre-established current is provided to a controller for controlling the printer in response to the current differential between the currents which is in turn a function of the operating temperature.

摘要： An RFID label with embedded tag is passed through an RFID antenna in a printer system, where the RFID antenna allows a roll of such labels to pass in close proximity to the antenna and still allow each individual RFID tag to be read and/or programmed. The RFID antenna module is formed with a transmission line coupled to an RF phase splitter, where in one embodiment, the transmission line is formed from two parallel conductive strips.

摘要： Each of a pair of spaced apart paper feed mechanisms within the paper feed system of a dot matrix line printer has opposite upper and lower portions thereof slightly angled relative to each other and disposed on opposite sides of and close to an elongated print station having a platen at one side thereof on which the paper feed mechanisms are mounted. Guides within the print station direct a length of paper introduced onto one portion of the paper feed mechanism through the print station and onto the other portion. Each paper feed mechanism is locked in a desired position on the platen using a manually operated lever arm arrangement having a mechanical advantage. Phasing or pitch adjustment between the opposite portions of each paper feed mechanism is accomplished by either of two arrangements which vary the position of a pulley engaging an endless belt between the opposite portions in combination with an opposite spring mounted pulley which bears against the inside of and tensions the endless belt. The opposite portions of each paper feed mechanism terminate in ramps which are angled to facilitate withdrawal of pins on the belt from apertures at the edges of the print paper. A lug arrangement at the end of the ramp prevents the toothed underside of the belt from slipping off of the meshing teeth of a pulley about which the belt extends. Slide members resiliently bear against and maintain the edges of the paper in contact with the belts.

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 paper stacker for use with a printer which prints connected sheets that are to be stacked in a folded relationship having a surface for receiving the paper with a frame surrounding the paper that is raised in relationship to the paper in order to maintain paper within the confines of the frame as the frame moves upwardly. The frame is balanced by a constant force spring, and is indexed by optical sensors. The frame includes two adjustable fences for variously sized paper which adjustably moves with paddles to press the paper edges downwardly in the stack. Pinch rollers for driving the paper include low inertia drive rollers formed of a relatively low density plastic material with a pair of idler rollers. To improve stacking, ironing tractor idler rollers iron the tractor perforations, and chains orient the catenary stacking movement.

摘要： In a dot matrix line printer in which an elongated hammerbank and an opposite conunterbalancing assembly are driven in opposing reciprocating fashion by a motor driven cam, the size of the cam drive motor and the current requirements thereof during startup of the printer are greatly reduced by applying current pulses to the motor in a pattern synchronous with the resonant frequency of the reciprocating cam driven system. The current pulses which are considerably smaller in amplitude than the continuous current conventionally used to produce startup are generated during alternate half cycles of the resonant frequency, causing the cam to rock back and forth until eventually the peak resistance presented by opposite lobes on the cam and the consequent maximum compression of springs within the cam followers coupling the cam to the hammerbank and the counterbalancing assembly is overcome. Thereafter, a continuous current of appropriate value is applied to the cam drive motor to produce reciprocation of the hammerbank at a desired steady state speed.

摘要： In a printer in which a shuttle and a counterbalancing mass are driven in opposing reciprocating fashion by a rotating, generally oval-shaped cam, the cam followers which couple the shuttle and the counterbalancing mass to the cam are castered to prevent skewing of the cam followers relative to the cam. Each of the cam followers is disposed between and rotatably mounted on a pair of opposite arms extending outwardly from a generally planar base of a castered yoke assembly, the planar base being pivotally coupled to a supporting member therefor which is either coupled to the shuttle or forms a part of the counterbalancing mass. In a first embodiment the pair of opposite arms extend from the planar base toward the cam so as to dispose the cam follower between the pivotal mount of the yoke assembly and the cam. In a second embodiment the pair of opposite arms extend from the planar base in a direction away from the cam so as to dispose the pivot point of the yoke assembly between the axis of rotation of the cam follower and the cam.

摘要： In a printer in which a shuttle is driven in reciprocating fashion by a rotating cam, a counterbalance assembly disposed on the opposite side of the cam from the shuttle and having a cam follower disposed along a common axis extending through the cam and a cam follower of the shuttle includes a mass in the form of a generally rectangular block mounting the cam follower at one of a pair of opposite ends thereof. Reciprocating movement of the block in response to rotation of the cam is provided by a pair of tapered flex pivots coupled to opposite ends of a base and extending upwardly and coupled to the opposite ends of the block. The end of the block opposite the cam follower receives a spring disposed against a reference surface to bias the cam follower against the cam.
