摘要： An impact printing device for printing bar code patterns on an information carrier, the patterns including a combination of parallel thin and wide bars separated by spaces wherein the wide bars can have an imprint width which is a multiple of the thin bars, comprising a movable type carrier, a plurality of bar code type elements on said type carrier, the bar code type elements including first type elements having a pair of imprint forming parallel thin bars and second type elements having a single imprint forming thick bar, and a plurality of print hammers each defining a print position of a print line and each operable selectively to successively impact combinations of the first and second type elements at the same print position to form completed bar code imprints at the print position having a wide bar imprint with a width greater than the single thick bars of the second type elements.

摘要： The disclosure describes in detail one of the most serious problems in connection with maintaining the operating life of print hammers at the high speeds of todays printers. Also described in detail is a structural arrangement to solve this problem without involving a major redesign of a print hammer module. A significant aspect of this solution is that a high speed print hammer is kept out of contact with structure that serves as a reservoir for the pivot pin lubricant.
