Abstract

PURPOSE: To improve the precision of the device and to simplify the mechanism by installing several fine magnetoelectric transducing elements for read-out at equal intervals in the horizontal surface vertical to the moving direction of the magnetic sensor moving system inside the case of a magnetic sensor. CONSTITUTION: A magnetic sensor 13 is in close contact with a magnetic stripe 14 placed on the surface of a magnetic recording medium 1 and moved in the arrow direction by a driving motor 8. At the time of write-in, a writing magnetoelectric transducing element 16 of the sensor 13 imprints magnetic signals in the width covering the whole of the stripe 14. At the time of read-out, three fine magnetoelectric transducing element 15 for read-out in the sensor 13 transduces the magnetic signals written in the stripe 14 to time sequential electric signals. Through this, the drop of read-out rate due to dirt or flaws of the medium and also the drop of the output due to oblique movement of the magnetic sensor and the magnetic stripe are prevented.

A magnetic sensor moving system including a driven gear 10, a ball screw 11, and a driven nut 12, and one reading magnetoelectric conversion element 15 provided with a winding 17 inside a case of the magnetic sensor 13. And a detecting unit by the write electric transducer 16.

[0003]

In this conventional magnetic stripe recording apparatus, since there is only one detection section by the magnetoelectric conversion element for reading inside the case of the magnetic sensor, the direction of relative movement between the magnetic sensor and the magnetic stripe. When the width in the direction perpendicular to is large, the magnetic output is remarkably reduced due to the skewing during relative movement of the medium and the magnetic sensor, which makes reading difficult. Therefore, since the skew is controlled within a readable range, the device becomes highly accurate and expensive, and the readable state tends to be unreadable.

When the reading width is narrowed,
It was easy for the media to become unreadable due to scratches and dirt.

[0005]

A magnetic stripe recording apparatus according to the present invention comprises a conveying system for conveying a medium, a leading edge detecting section for stopping the medium at a predetermined position, a magnetic stripe section on the medium and a magnetic sensor. A magnetic sensor moving system for always moving relatively at a constant interval and a constant speed, and a detecting section by a fine magnetoelectric conversion element for reading inside the case of the magnetic sensor, a horizontal plane perpendicular to the moving direction of the magnetic sensor moving system. There are several at regular intervals inside.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a side view showing an embodiment of the magnetic stripe recording apparatus of the present invention.

The medium 1 is conveyed in the direction of the arrow by a medium conveying system composed of a conveying motor 2, a conveying belt 3, a conveying pulley 4 and a conveying roller 5. At this time, the tip of the medium 1
After passing through the front end detecting portion constituted by the light emitter 6 and the transmitted light sensor 7, the transport motor 2 is stopped for a certain period of time, and the medium 1 is stopped at a predetermined position.

The information writing operation will be described below with reference to the top view of the magnetic stripe recording apparatus of the present invention shown in FIG. In the above operation, the magnetic sensor 13 is positioned at a position which is always in close contact with the magnetic stripe 14 arranged on the surface of the medium 1 stopped at a predetermined position, and the drive motor 8, the drive gear 9, the driven gear 10, the ball screw 11 and the driven nut are placed. 12
The magnetic sensor moving system, which is composed of, moves in the direction of the arrow while constantly adhering at a constant speed. At this time, the write information moves in the direction of the arrow. At this time, the write information is the presence or absence of a magnetization transition line which is perpendicular to the arrow direction and has a fine constant interval as a minimum unit.
4 is transferred as a magnetic signal. The write magnetoelectric conversion element 16 inside the case of the magnetic sensor 13 transfers the magnetic signal to the entire area as a width covering the entire magnetic stripe 14.

Next, regarding the information reading operation, a top view of the magnetic stripe recording apparatus of the present invention of FIG. 2, a mounting top view of the magnetoelectric conversion element in the magnetic sensor of the magnetic stripe recording apparatus of the present invention of FIG. 3, and a top view of FIG. Description will be given with reference to a mounting side view of a reading magnetoelectric conversion element in a magnetic sensor of the magnetic stripe recording apparatus of the present invention. Similarly to the writing operation, while bringing the magnetic sensor 13 into close contact with the magnetic stripe 14,
It is moved at a constant speed by the magnetic sensor moving system.
At this time, the magnetic sensor 13 is placed inside the case of the magnetic sensor 13.
The three fine reading magnetoelectric conversion elements 15 are arranged in a horizontal plane perpendicular to the moving direction of the magnetic stripe 14
The magnetic signal written therein is converted into an electric signal in time series, and three data groups are temporarily held.

Next, for one of the above-mentioned three data groups, the presence or absence of data abnormality is confirmed. The data is a time series data group of “1” and “0” depending on the presence or absence of the magnetic transition line.

At this time, since the detection section of the reading magnetoelectric conversion element 15 has a smaller detection width than in the prior art as shown in FIGS. 3 and 4, there is a magnetic transition line with respect to the skew of the medium 1. It becomes easy to distinguish between a copy and a blank copy, and the recognition rate is improved.

However, by reducing the detection width, scratches,
Bit loss easily occurs due to dirt and the like. Therefore,
Due to a parity check, etc., the second and the third will be displayed in case of an abnormality.
As the second data group is checked, the processing is stopped and the data is recognized under normal conditions.

[0013]

As described above, in the magnetic stripe recording apparatus of the present invention, since the read magnetoelectric conversion element for converting the magnetic data of the magnetic stripe into an electric signal is minute and plural, the reading rate due to dirt and scratches on the medium is high. In addition to preventing the decrease, the output of the magnetic sensor and the magnetic stripe is prevented from being decreased, so that the accuracy and mechanism of the device can be reduced and simplified, the reliability of the device is improved, and the cost can be reduced.
