  • Patent number: 6244765
    Abstract: An inkjet printing mechanism includes a vibration isolating attachment system for securing a drive belt to an inkjet printhead carriage for increasing print quality by isolating the carriage from multi-directional vibrations generated by a carriage drive motor while propelling the carriage during printing. The vibration isolating member is of a resilient material having a first end coupled to a drive mechanism interface member which is joined to the belt, a second end coupled to a carriage interface member supported by the carriage, and a body section between the first end and the second end. Two or more vibration isolating members may be used, with a preferred shape being an I-shaped cross section. An inkjet printing mechanism having such a vibration isolating attachment system, and a method of method of isolating an inkjet printhead carriage from vibrations generated by a carriage drive motor, are also provided.

  • Patent number: 6171002
    Abstract: A magnetic character reader capable of reading information recorded on a record sheet with an optional printer, the size of the magnetic character reader being reduced by use of a shortened record sheet transport passage. The magnetic character reader 50 includes: a reading unit 35 having a magnetic head 33 and a head presser 34; and a transport mechanism section 30 having a paper feed roller 21 and a paper pressing roller 22. The transport mechanism section 30 is arranged at a position adjacent to a reading unit 35 on reference line L which extends in a direction substantially perpendicular to a transport direction of a check P from a reading section of the reading unit 35. A paper feed roller 21 includes three transport sections 21a1 to 21a3. Three paper pressing rollers 22a1 to 22a3 which correspond to the three transport sections 21a1 to 21a3 also are provided.
