摘要： An apparatus for use in reading magnetic waveforms, like E13B, which are printed on a carrier like financial documents or checks. The waveforms include positive and negative peak values and substantially zero values occurring at predetermined times for a predetermined character. A shaft encoder is used to develop a nominal count which is correlated to the velocity of the carrier. Teh nominal count is used to generate a timing clock which is used to clock the positive and negative peak values and substantially zero values into registers for subsequent character recognition. The occurrence of the timing clock is adjusted by utilizing the occurrence of a positive or negative peak itself.

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 plurality of vertically aligned sensing members scan a matrix type bar code on a document. During the scanning of the bar code, the time period between the detection of succeeding bars is determined. An average time period which occurs during the detection of a number of bars is then generated. Each succeeding time period generated as a result of detecting the next bar is divided by the average time period to determine the presence or absence of the bar in addition to the number of spaces preceding the detected bar. This information is used in decoding the bar code label.

摘要： An impact hammer assembly for a high speed printer includes first and second permanent magnets having opposite poles disposed adjacent to each other and having a gap therebetween. The magnets create flux lines extending across the gap. A print hammer includes a hammer beam and a hammer head. The print hammer is movable between a rest position and a print position. The hammer beam is disposed in the gap between the first and second magnets. A coil is disposed on the hammer beam and perpendicular to the magnetic flux lines. Circuitry generates a current in the coil and controls the direction of current flow in the coil, such that when current flows in the coil in a first direction, the print hammer moves towards the print position and when current flows in the coil in a second direction, opposite to the first direction, the print hammer moves towards the rest position.

摘要： A method and apparatus for recognizing MICR characters having positive peak values, negative peak values, and substantially zero values occurring at predetermined clock positions along the associated waveform. A first count derived from the speed of the MICR characters moving past the associated reader is used for deriving nominal clock pulses for clocking the peak and zero values into storage registers associated with the apparatus. The occurrences of positive and negative peak values are used to adjust the first count depending upon whether the MICR characters are moving faster or slower than a nominal rate, with the adjustment being used to provide an adjusted count which is used for determining subsequent clock pulses.
