Abstract

PURPOSE:To detect surely the presence of magnetic flux by magnetizing unidirectionally a prescribed range at the end of magnetic stripes formed on a card so as to form a detecting area and detecting the area with a stationary magnetic sensor. CONSTITUTION:The prescribed range at the right end of a magnetic stripe 2 provided vertically in the inserting direction (arrow) to a magnetic card 1 is magnetized unidirectionally to form a detecting area 3, and a card data area 4 inverses magnetization in response to the card data. In inserting the magnetic card 1 to an inserting inlet 6 corresponding to the position of a magnetic sensor 8 of the card reader 5 for the detecting area 3, the magnetic sensor 8 detects surely the magnetic flux of the detecting area 3. If the sensor 8 does not detect the magnetic flux, even if the card has no magnetic stripe 2, it is discriminated that the card is not applied to the card reader 5, a shutter 7 keeps closing state.

変化が生じないので、検知不可能となる。The magnetic stripe described above is detected by reading the presence of magnetic data on the magnetic stripe, but since magnetic data is recorded by changes in magnetic flux in the length direction of the magnetic stripe, when reading with a magnetic head, the card If the card is not moved in the length direction of the magnetic stripe, changes in magnetic flux cannot be detected and it is not possible to determine whether magnetic data exists.Moving the card in a direction perpendicular to the direction of the magnetic stripe does not cause a change in magnetic flux. becomes undetectable.
