  • Patent number: 7417822
    Abstract: A magnetic information medium recording/reproducing device may include a turnable drum whose outer peripheral face forms a medium feeding path for a magnetic information medium and a feeding mechanism for carrying the medium along the outer peripheral face of the drum while pressing the medium against the outer peripheral face of the drum. The drum may be formed in a hollow cylindrical shape having an inner peripheral wall and a plurality of inner support rollers are disposed for supporting the drum from the inner peripheral wall side of the drum. The drum may be held by the inner support rollers and the feeding mechanism, and one of the inner support rollers may be disposed near a magnetic head and may be urged against the inner peripheral wall of the drum.

  • Publication number: 20070069031
    Abstract: A card carrying device may include a stacker in which a plurality of cards may be stacked, a card pushing-out member for engaging with the rear edge of a card at a lowest position of the cards to push the card at the lowest position outside from the stacker, a carrying-out roller for carrying the card outside from the stacker, and a card pushing-up member for pushing up other cards stacked on the card at the lowest position in an upper direction in a period after the carrying-out roller comes in contact with the card at the lowest position and before the card at the lowest position has been carried outside from the stacker. The card pushing-out member and the card pushing-up member may be formed as one piece of a card pushing out-and-up member. The card pushing out-and-up member, i.e., the card carrying-out member may include an engagement part, a first guide part and a second guide part.
