发明名称 Magnetic card reader using two multi channel magnetic heads that can read magnetic track data in two separate and distinct directions
摘要 A magnetic card reader includes a first multi-channel magnetic head for reading signals from a magnetic card which inserted in a first direction, a second multi-channel magnetic head for reading signals from a magnetic head which is inserted in a second direction, a plurality of switching circuits for delivering signals supplied from the first multi-channel magnetic head and the second multi-channel magnetic head at respective channels thereof after switching each set of common channels of the first and second multi-channel magnetic heads, a plurality of amplifier circuits for amplifying output signals from the plurality of switching circuits, respectively, and a decision circuit for determining the direction of insertion of the magnetic cards on the basis of the output signals from the switching circuits and for selectively operating the switching circuits so as to deliver output signals associated with the direction of insertion of the magnetic cards.
