摘要： A hammer bank system for use in a high speed impact printer includes a movable hammer bank in which the hammer spacing is twice the character spacing. A hammer bank controller is used to move the entire hammer bank between two selected hammer bank positions. In one hammer bank position, the hammers are aligned with odd character positions and in the other hammer bank position, the hammers are aligned with the even character positions. The hammer bank controller in response to a move command signal from the printer logic section drives the hammer bank (in a velocity mode) from one of its positions to the other first at an increasing velocity, followed by a constant velocity, until the bank is at a selected distance from the desired position, at which time the hammer bank velocity is decreased to zero and the hammer bank is substantially at the desired position. The controller switches to a position mode in which a position signal is used in a position servo loop to lock the hammer bank at the desired position. In normal operation when the bank is switched to the position mode, a move complete signal is fed back to the printer logic section to terminate the move command signal. Positioning initialization circuitry is also included to automatically drive the hammer bank to one of its desired positions.

摘要： A printer for selecting automatically types of numerals and/or characters in response to input signals and for printing the selected types of numerals and characters on a printing paper, in which a plurality of type wheels are arranged rotatably on a shaft at regular intervals. Each of the type wheels has an even number of permanent magnets radially arranged from the center of the type wheel at regular intervals in the alternating arrangement of magnetic polarities of the permanent magnets. Type characters are fixed along the periphery of each type wheel at respective projections each arranged between adjacent two of the permanent magnets. One of the types is selected by rotating each type wheel in the clockwise or counterclockwise direction by driving alternately a pair of electromagnets arranged oppositely to one of the types and the pole of one of the permanent magnets respectively until the selected type opposes a print hammer.

摘要： In a dot matrix printer, a single main shift register is loaded in the non-printing time during which a transversely shuttling print bar is changing direction with the complete dot row to be printed on the next printing pass of the print bar. A custom VLSI integrated circuit comprising a serial loaded 2772-bit main shift register and a parallel loaded 132-bit bidirectional parallel-to-serial output shift register is provided. The main shift register has one storage cell for each dot that can be printed across the dot row during a single pass of the print bar. Parallel output taps physically placed along the main shift register provide simultaneous serial output of the storage cells between each tap. The number of bits stored between each output tap is the number of dots each individual print hammer can print on a single pass of the print bar. The 132-bit output shift register is utilized to limit the number of package pins and to compensate for the direction of motion of the print bar. The parallel outputs of the main shift register comprise the parallel inputs of the output shift register. Dot Generation Logic is provided to map printable characters and data through dot image character sets and to load the 2772-bit main shift register with the exact dot image of the data to be printed during the next pass of the print bar.

摘要： A variable speed printing (VSP) adaptor for a dot matrix printer which includes a monitoring means having a plurality of devices each capable of assuming one of two states. The monitoring means monitors the state of the pattern data to be printed, and, in the preferred embodiment, the monitoring means comprises a counter which is preset with a number equal to the number of column scans with a dot print line. The pattern data to be printed is scanned in a forward direction, i.e., in the normal printing direction starting at the first print position and the count in the counter is decremented one count for each column data scanned. During the time interval between when this data is latched and the actual hammer actuation, the pattern data is scanned in the backward direction starting at the last print position. Each time the column data for a backward scan is zero, i.e., no dot to be printed, prior to sensing a non-zero column, the count in the counter is decremented one count. The printing operation continues in the interleaved forward/backward scans until the count in the counter reaches a reference level such as zero. Upon sensing this reference level in the counter, a control signal is generated which indicates that the printing of the dot row is complete and initiates movement of the paper to the next dot row position. In an alternate embodiment, the monitoring means comprises a random access storage device.
