  • Patent number: 6814830
    Abstract: A hot-stamping foil tape cassette comprises a hot-stamping foil tape transferred by pressure application together with a value-added medium to the value-added medium and a windup reel for winding up the hot-stamping foil tape. The reel on which the hot-stamping foil tape is wound is stored in a cassette case. A shutter is included which at the time of hot-stamping transfer is in a protective position that protects the hot-stamping foil tape. The shutter at the time of hot-stamping transfer withdraws to a withdrawal position that does not interfere with action of the hot-stamping transfer. After hot-stamping, by the shutter, the hot-stamping foil tape can be peeled from the value-added medium. A foil-peeling mechanism for a hot-stamping device, a peeling method for a hot-stamping foil and a control method for a hot-stamping foil tape cassette are also disclosed.

  • Patent number: 6672357
    Abstract: This invention relates to a hot-stamping device comprising a stamping arm with one end being a free end, a stamping section adapted to apply pressure to a hot-stamping foil positioned at the free end to a value-added medium such as ticket wherein the hot-stamping foil is transferred to the value-added medium. A first cam, in contact with said stamping arm, is used for moving a stamping section to close proximity of the value-added medium. A first drive section driving said first cam and a second cam for bringing pressure-exerting load to bear on the stamping section is used to move to close proximity a value-added medium. A second drive section is used for driving a second cam.

  • Publication number: 20010025885
    Abstract: A magnetic card reader 1 is adapted to make a magnetic card and magnetic heads 4 to relatively move with respect to each other and also adapted to demodulate data, which is recorded on the magnetic card and obtained by the magnetic heads 4. This magnetic card reader 1 comprises two magnetic heads 4a and 4b arranged in a direction, in which each of the magnetic heads 4a and 4b relatively moves with respect to the magnetic card, and adapted to take in the same data from the magnetic card and to obtain two demodulated data, an error detecting portion 5 for detecting an error in at least one of the two demodulated data, and an error correcting portion 6 for correcting the error, which is detected by the error detecting portion 5, by using the other demodulated data. When a read error is detected, the error correcting portion 6 corrects an erroneous part of one of the two demodulated data into normal data by using the other demodulated data.

  • Patent number: 6199760
    Abstract: When, in the case where card take-in means 3 takes in a magnetic card 10, a magnetic head 4 outputs a predetermined reproducing signal, the magnetic card is taken in; and when the predetermined reproducing signal is not outputted by the magnetic head, the magnetic card take-in operation is stopped. The magnetic head 4 is provided near a card inserting inlet 2, so that, when the card take-in operation is stopped, the rear end 10a of the card 10 is protruded from the card inserting inlet 2.
