Magnetic head of magnetic reader

#This invention relates to a magnetic head used in a magnetic reader.

#A magnetic head of a magnetic reader adapted to read out data stored on a magnetic storage medium is well known. An example of a conventional magnetic head as is used for a magnetic card reader 70 will be described hereunder in reference to FIG. 7. The magnetic card reader 70 reads data from a magnetic stripe of the magnetic card 71 through a magnetic head 72 coming in contact with a surface of the magnetic card 71 passing through a guide groove (not shown) of the magnetic card reader 70. The magnetic card reader 70 comprises the magnetic head 72, an A/D converter 74 connected to the magnetic head 72 via an interface cable 73 and a control unit 76 connected to the A/D converter 74 via an interface cable 75.

#The magnetic head 72 has a core and a coil wound around the core. The control unit 76 is a computer having a CPU, a memory, a hard disc, a CD-ROM drive and a floppy disc drive. Though not shown, a display (display device), a keyboard (input device) and a printer (output device) are connected to the control unit 76 via interface cables.

#FIG. 1 is a block diagram schematically illustrating a magnetic card reader;

#FIG. 2 is a diagram schematically illustrating an internal construction of a card reading station;

#FIG. 3 is a partially cutaway perspective view showing a magnetic head incorporated in the card reading station;

#Details of a magnetic head used in a magnetic reader according to this invention will be more fully understood from the description of a magnetic head used in a magnetic card reader given hereunder in reference to the accompanying drawings.

#FIG. 1 is a block diagram schematically illustrating a magnetic card reader 1, FIG. 2 is a diagram schematically illustrating an internal structure of a card reading station 2 and FIG. 3 is a partially cutaway perspective view showing a magnetic head 17 incorporated in the card reading station 2. In FIG. 3, a core 19 of the magnetic head 17 has its distal end 19a in contact with an upper surface of a magnetic card 23. FIG. 3 shows the interior of a housing 18 by partially cutting a synthetic resin 22 filled in the housing 18.

#As will be apparent from FIG. 1, the magnetic card reader 1 comprises the card reading station 2 adapted to sense data stored on a magnetized layer 26 of the magnetic card 23 in the form of electric signals and a data control station 4 (terminal node) connected to the card reading station 2 via an interface cable 3. The data control station 4 is a computer comprising a CPU (central processing unit), a memory (auxiliary memory), a hard disc, a CD-ROM drive and a floppy disc drive. A display 5 (display device) adapted to output data in the form of character information, a keyboard 6 (input device) adapted to add and/or change data and a printer 6 (output device) adapted to output the data in the form of printed information are connected to the data control station 4 via interface cables 7, 8.
