  • Patent number: 4819109
    Abstract: A transducer carriage 1 is slidably mounted on and between parallel guide rails 2a, 2b by two spaced pairs of inclined bearing rollers 3a, 4a, 3b, 4b, on one side and a single intermediate pair of such rollers 3c, 4c on the other side. The lower intermediate roller 4c is elastically mounted to the carriage by a rubber shaft ring 9 and exerts a biasing force on its guide rail, to thereby maintain the remaining fixedly mounted rollers in stable contact with their associated rails.

  • Patent number: 4740946
    Abstract: An improved carriage assembly for linearly reciprocating a data converter pickup or the like. Magnetic circuits are provided on each side of a carriage, and a driving coil wound on a transversely solid type coil bobbin which surrounds the carriage, is magnetically linked with the two magnetic circuits. Guide rails are provided between the carriage and the two magnetic circuits. The moving elements including the carriage, the driving coil, and the bobbin are supported on the guide rails for linear movement therealong by rollers.
