Embodiment Construction

[0022] Details of a magnetic head used in a magnetic reader according to the present invention will be more fully understood from the following description of a magnetic head used in a magnetic card reader with reference to the accompanying drawings.

[0023] figure 1 is a block diagram schematically showing a magnetic card reader 1, figure 2 Schematically shows the internal structure of the card reading station 2, and image 3 is a partially cutaway perspective view showing the magnetic head 17 included in the card reading table 2 . exist image 3 In this case, the magnetic core 19 of the magnetic head 17 brings its tip end 19a into contact with the upper surface of the magnetic card 23. image 3 The inside of the case 18 is shown by partially cutting through the synthetic resin 22 filled in the case 18 .

[0024] as from figure 1 Clearly, the magnetic card reader 1 comprises a card reading station 2 suitable for sensing data stored as electrical signals on the magnet...

Abstract

This invention aims to provide a magnetic head for a magnetic reader improved so that the data can be read out from the magnetic storage medium with high security, that is, without an anxiety that the data might be illegally read out and, even if the data is illegally read out, such illegally read out data can not be used by the illegal person. The magnetic head 17 of a magnetic reader for reading data stored in a magnetic card 23 is provided with a core having a coil for converting the data of the card 23 into an analog signal, an A / D conversion chip 20 for converting the analog signal into a digital signal, and a microprocessor 21 for encrypting the digital signal. The A / D conversion chip 20 and the microprocessor 21 (IC) are fixed via a synthetic resin 22 in a housing 18.

Description

technical field [0001] The present invention relates to magnetic heads used in magnetic readers. Background technique [0002] Magnetic heads for magnetic readers suitable for reading data stored on magnetic storage media are well known. Refer below Figure 7 An example of a conventional magnetic head for a magnetic card reader 70 is illustrated. The magnetic card reader 70 reads from the magnetic strip of the magnetic card 71 by means of the magnetic head 72 in contact with the surface of the magnetic card 71 passing through the guide groove (not shown) of the magnetic card reader 70. Read out the data. The magnetic card reader 70 includes a magnetic head 72 , an analog-to-digital converter 74 connected to the magnetic head 72 via an interface cable 73 , and a control unit 76 connected to the analog-to-digital converter 74 via an interface cable 75 . [0003] The magnetic head 72 has a magnetic core and a coil wound on the magnetic core. The control unit 76 is a computer...
