  • Patent number: 6042285
    Abstract: An airline ticket printer includes a magnetic reading and writing station that has a read/write head for recording information on, or reproducing information from, a magnetic stripe carried on the ticket. The ticket is driven past the read/write head by a drive mechanism that contacts the ticket at a substantial distance from the read/write head so that the magnetic stripe is free to flex independently of the portion of the ticket that is in contact with the drive mechanism. More satisfactory contact between the read/write head and the magnetic stripe is thereby achieved.The ticket printer also has a second reading/writing station in series with the first station along a ticket feed path, so that errors in reading or writing by the first station may be detected and/or corrected at the second station.A ticket feed path is constructed using feed modules that are mounted on pins extending from a vertical mounting plate.

  • Patent number: 6029971
    Abstract: A belt displacement operation is periodically carried by the pick mechanism 11 of a sheet feeding apparatus, when the number of sheets fed has reaches a predetermined value. The motor 34 is driven in reverse for a predetermined time, so as to cause rotation of the belt 28 in the opposite direction to that during feeding. Since the pick pulley 26 is supported on the shaft 38 by means of a one-way clutch 40 so that it does not rotate during the reverse rotation of the belt 28, displacement of the belt 28 occurs relative to the pick pulley 26, so that in subsequent pick operations, a different portion of the belt 28 engages the stack 18 so as to pick a sheet, than had displacement of the belt 28 not occurred. This reduces the risk of localized portions of the belt 28 becoming more worn than others, due to more frequent engagement with the stack 18.
