Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic card information recording device for recording information on a magnetic card, and in particular, to a magnetic card information recording device that records information on a magnetic card. The present invention relates to a support mechanism in an information recording device for an information card, which enables good contact between a magnetic recording band and a magnetic head by bringing them into contact with a contact pressure of .

(Prior Art) Magnetic cards (thin carriers made of plastic or paper with a magnetic stripe pasted on the surface) have been widely used for a long time. It is often used as a credit card that allows you to purchase products or receive services, and as a cash card that allows you to withdraw cash deposited at a bank. A telephone usage card that allows you to use the telephone within a certain amount of money, a ticket issuing card that allows you to issue a ticket with a fare within the amount you have paid in advance, or a ticket issuing card that allows you to board a train or bus within the amount that you have paid. 2. Description of the Related Art Prepaid cards, such as multi-ticket cards that can be used for travel, have been widely used.

Furthermore, depending on the purpose of use, specific signals or codes may be recorded, and when the recorded content matches the recorded content that has been set in advance, it may be used as an admission permit card that opens a door or gate, or as a product price tag. It has also been widely applied to POS cards that can be installed in advance and record which products were sold and when each time a product was sold. Although the purpose of each of these uses is different, the essential act of pasting or coating a magnetic stripe on a card-shaped carrier and magnetically recording information on the magnetic stripe is the same. .

Figure 1 shows the appearance of a conventional magnetic card l.
It is made of a carrier such as cardboard or plastic, and a magnetic stripe 2 is coated on the surface of the magnetic card 1 in parallel to its length. When recording information using this magnetic card 1, the magnetic card 1 is attached to the first
It is conveyed at a constant speed in the direction of arrow A in the figure. Then, the magnetic head is fixed, the fixed magnetic head is brought into contact with the surface of the magnetic stripe 2, and information is recorded on the magnetic stripe 2 as a magnetic change according to a conventionally known theory. The magnetic stripe 2 shown in FIG. 2 schematically shows the state in which the magnetic recording has been completed, and the magnetic stripe 2 has a parallel recording section 3 as the I! A magnetization pattern is formed in a direction perpendicular to the feeding direction, and information can be read only along the direction of the arrow in which the magnetic card I is fed.

However, when information is recorded on the magnetic card 1 using the conventional recording method, the magnetic head is fixed and the...
Information is magnetically recorded in the direction in which the n-ki card is transferred, and for this reason, in the conventional θl-ki card, for example, when specified by the JTS standard, a maximum of 72
It could only record text, and the amount of information that could be recorded was extremely limited.

Due to these shortcomings, in recent years, there have been new devices that record a large amount of information on thin card-shaped carriers, such as IC cards that have a built-in high-density integrated circuit, and optically record large amounts of information using laser light. A so-called laser card has also been developed. However, Ic
Cards are expensive, and the contacts for inputting and outputting data must be processed with high precision.
It had the disadvantage of being expensive. Additionally, zero-order laser cards, which were extremely susceptible to static electricity, can store an extremely large amount of data, and the laser cards themselves are relatively inexpensive.

However, laser card writing/reading devices for writing information to and reading information from laser cards require extremely high accuracy and have the drawback of being extremely expensive.

New recording methods have been proposed to overcome these conventional drawbacks and record a large amount of information at low cost. In this new proposal, a magnetic stripe is applied to the surface of a carrier to form a magnetic card, and this magnetic card records information sequentially on tracks diagonal to the direction of travel. The amount can be extremely large, and the manufacturing cost of the card itself can be reduced. However, if a rotating magnetic head is brought into contact with the magnetic stripe and the head surface of the magnetic head is operated in an oblique direction with respect to the traveling direction of the magnetic stripe, it is necessary to improve the adhesion between the magnetic head and the magnetic stripe. It is something that must be kept.

However, the carrier of a magnetic card is made of plastic or paper, and even though it is flexible, it must be somewhat strong for convenience in storage and carrying. It is difficult to move the magnetic head while accurately bending it to match the rotating curved surface of the magnetic head. In addition, when a magnetic card is run with a bend, the contact between the magnetic head and magnetic stripe must always be maintained with a predetermined elastic force, and if the contact pressure is high, the rotating head will be subject to severe wear. If the contact pressure is small, the magnetic head will move away from the magnetic stripe, making it impossible to write or read information.

[Means for solving problems]

In view of the above-mentioned drawbacks, the present invention provides an information recording device for a magnetic card in which information can be recorded by a rotating magnetic head, using a magnetic card in which a magnetic recording band is provided on a thin flat carrier. Provided is a support mechanism for a magnetic card information recording device, characterized in that a support is provided to press the magnetic card from the back side, and a space is formed on the surface of the support with which the magnetic card comes into contact to release the contact pressure of the magnetic head. It is something to do.

[Effect]

In the present invention, the magnetic card is bent by the support along the radius of rotation of the rotary head, and the support presses the back surface of the magnetic card so that the magnetic stripe can be brought into close contact with the rotary head. At this time, on the back side of the magnetic stripe, the support body has elongated grooves formed in the running direction of the rotating magnetic head.
No pressing force is directly applied to the back side of the magnetic stripe. Therefore, even if the rotating head is in contact with the magnetic stripe, the pressing force is absorbed by the elasticity of the magnetic card. Therefore, if an unnecessarily large force is applied to the magnetic card by the rotating head, the magnetic card will deflect toward the groove of the support, and the amount of deflection will absorb the pressure from the rotating head. Can be done. Therefore, the rotating head and the magnetic stripe can always be in contact with a constant pressure, and when unnecessary force is applied, the elasticity deforms in the direction of the groove, preventing damage and wear on the rotating head. Can be done.

Next, in the holding mechanism 17, the magnetic card writer/reader 1
It is assembled on an inclined base 40 by bending a thin plate attached to the internal base of 0. This base 40 has almost the same inclination angle as the base 20, and a shaft 41 is fixed to the top of the base 40.

This rotating cylinder 22 is in rolling contact with a bearing 55 and is rotated at high speed by a motor (not shown).

Next, FIG. 8 shows a state in which the guide rail 14, the helical recording mechanism 15, and the guide rail 16 are cut horizontally to show the positional relationship in a plane.

As mentioned above, a semi-circular guide plate 25 is fixed to the outer periphery of the lower fixed cylinder 21, and between this guide plate 25 and the sliding surface 27 there is a circular arc-shaped part that is large enough to allow the magnetic card l to pass through. A guide groove X is formed. The thickness of the end of the first guide rail 14 is the same as that of the lower fixed cylinder 2.
The guide piece 60 is hollowed out with a circumferential curvature of 1, and is bent into a U-shape at the top and bottom, so that the end of the guide piece 60 approaches the end of the guide plate 25. For this reason, guide rail 1

It is close to the end. The guide groove W formed in the idle rail 16 through which the magnetic card l can be inserted is positioned so that its extension direction is continuous with the guide groove X formed by the guide plate 25 and the sliding surface 27. .

FIG. 9 shows the above-mentioned rotary cylinder 22 and holding mechanism 17 viewed from above. The solid line state of the presser body 42 shows the state in which the rod 48 is moved in the D direction by the threaded rod 51 and the presser body 42 is in contact with the outer periphery of the rotating cylinder 22. In addition, in the state of the presser body 42 indicated by the broken line, the presser body 42 is
is far away, indicating the standby state.

FIG. 10 shows the above-mentioned presser body 42 viewed from the opposite side to that shown in FIG. 6, and shows the curved inner circumferential surface of the presser body 42. As shown in FIG. This presser body 42 is formed with a gentle curve in a slightly dogleg shape, and a presser surface 58 having a radius of curvature that is approximately the same as the outer circumferential diameter of the rotary cylinder 22 is formed on its inner circumferential surface. An escape groove 59 in the shape of a groove for the tip of the rotary head 24 is cut in the center. This relief groove 59 is located at a position that coincides with the running direction of the rotating rod 24 when the presser body 42 is positioned close to the rotating cylinder 22 in FIG.

FIG. 11 shows a case in which the presser body 42 approaches the outer periphery of the rotary cylinder 22 and the magnetic card l is held between them in FIG. 9. It shows the relative arrangement of each part. The state shown in FIG. 11 is the state cut in the direction perpendicular to the paper plane in FIG. 9.

As mentioned above, the magnetic card l is bent around the outer periphery of the rotating cylinder 22 along its curved surface.

The presser body 42 approaches from the back side of the magnetic card 1 by a force of 5 degrees of spring, and the magnetic card 1 is bent according to the curved surface of the presser surface 58 so as to be approximately equal to the curvature of the rotation radius of the rotary head 42. In this state, the magnetic stripe 2 attached to the magnetic card 1 is in contact with the rotating head 24, but the relief groove 59 formed on the presser body 42 is at almost the same height as the magnetic stripe 2. The width of the relief groove 59 is slightly larger than the width of the magnetic stripe 2. When the back side of the magnetic card 1 is pressed by the presser body 42, the cavity of the relief i1$59 does not come into contact with the back side of the magnetic card 1, and no pressing pressure is generated on the back side of the magnetic stripe 2. Therefore, the magnetic card 1 can be bent toward the inner surface of the escape groove 59, and the magnetic stripe 2 can be brought into contact with the rotating head 24 with elasticity.

Next, the operation of this embodiment will be explained.

First, the magnetic card 1 on which the magnetic axis is to be recorded is inserted into the insertion slot 11 from the C direction in the state shown in FIG. 4 or FIG. Then, the magnetic card 1 is held between the rollers 12 and 13 as shown in FIG. 12, and is drawn into the magnetic card writer/reader 10. The magnetic card 1 carried in by the rollers 12 and 13 is further transported to the back and inserted into the inside of the first guide rail I4. When the magnetic card 1 is inserted into the guide rail 14, the upper and lower edges of the card 1 are inserted into the guide Rz, which is bent into a U-shape, and the card 1 slides vertically without wobbling. .

At this time, since the magnetic card l passes through the detector 33,
The user will know that the magnetic card l has been inserted. Since the motor 32 is rotating, the feed roller 30 rotates on the surface of the magnetic card 1, and the magnetic card 1 can be slid further inward.

After passing through the guide groove Z, the magnetic card l will be transferred to the helical recording mechanism 15, but the width between the steps of the lower fixed cylinder 21 and the upper fixed cylinder 23 is the same as the width of the magnetic card 1. The upper and lower parts of this stepped part are covered like eaves by temporary guides 25 and 26, so the magnetic card l is placed in the guide groove XSY formed on this sliding surface 27 and 28. The edges will be held and guided by being bent to the radius of curvature of the sliding surfaces 27,28.

Then, when magnetic card 1 moves further, magnetic card 1
The tip of the guide rail 16 reaches the guide rail 1.
6, the guide piece 61 is inserted into the guide groove W formed above and below. When the magnetic card 1 is inserted into the guide rail 16, it comes into contact with the tension roller 35, but since the tension roller 35 is rotated by the motor 37, the magnetic card 1 is inserted into the guide groove X,
It is held in the Y position and bent so that the planes of both ends are at right angles, and can be freely moved by the feed roller 30 and the tension roller 35. At this time, the tip of the magnetic card 1 is detected by the detector 38, and the detector 38 detects the state in which the magnetic card 1 is completely held on the sliding surface 27.28. When the position is detected, the rotating cylinder 22 is rotated, the motor 46 is simultaneously rotated, the threaded rod 51 is rotated, and the slider 47 is moved along the slider guide 45. Therefore, the rod 48 moves in the direction D in FIG. 6 and acts to stretch the spring 50. Therefore, the actuating body 43 is pushed by the spring 50, and the presser body 42 is moved as shown in FIGS. 6 and 9.
It is pushed in the E direction in the figure, and the pressing surface 58 of the pressing body 42 is moved in the direction of the sliding surfaces 27 and 28. Therefore, the pressing surface 58 of the pressing body 42 comes into contact with the back surface of the magnetic card 1, and prevents the magnetic card 1 from being bent with an accurate radius of curvature.
The rotary head 24 is biased from the back side so that it can surely come into contact with the rotary head 24. In Figure 13, the magnetic card 1 is placed on the sliding surface 27.28.
The figure shows a state in which it is in contact with and is pressed by the presser body 42 from its back surface.

In this FIG. 13, when the magnetic card 1 is urged by the pressing surface 58 of the pressing body 42 and is bent with approximately the same radius of curvature as the rotating cylinder 22,
The cross section is as shown in FIG.

Even if the magnetic card l is bent by the curvature of the holding surface 58 in this holding body 42, the holding surface 58
The length direction of the escape groove 59 formed in the center of the rotating head 2
4 in the scanning direction. For this reason, the magnetic card l
Although the back surface of the magnetic strip 2 is pressed by the presser body 42, the cavity of the relief groove 59 is located on the back surface at the position of the magnetic stripe 2, and no bias is applied from the back surface. In this state, the contact surface of the rotary pad 24 comes into contact with the magnetic stripe 2, but since the top and bottom of the magnetic card l are pressed by the pressing surfaces 58, the magnetic card l can escape due to its elasticity. It can be bent into the internal space of a59, and the magnetic stripe 2 will also be bent at the same time. Therefore, by pressing the back side of the magnetic card 1 with the holding surface 58, the magnetic stripe 2 comes into contact with the rotating head 24, but the pressure from the holding surface 58 is not directly transmitted to the rotating head 24, and the magnetic stripe 2 A biasing force softened by elasticity is transmitted. This magnetic card
The biasing force caused by the bending can absorb some distortion of the rotating head 24, and even if the rotating head 24 rotates somewhat eccentrically due to rotational errors or accuracy errors, contact with the magnetic stripe 2 will not occur on the magnetic card. The magnetic stripe 2 is absorbed by the elasticity of the rotary head 24, and can be biased so that the magnetic stripe 2 and the rotating head 24 come into contact with each other reliably. Also spring 5
Since the pressing force of the pressing surface 58 due to the elastic force of 0 is not directly transmitted to the rotating head 24, but is transmitted by the elasticity of the magnetic card l, a large force is suddenly transmitted from the pressing surface 58 to the rotating head 24. However, since the magnetic card 1 is only deformed and pushed into the escape groove 59 without being directly transmitted to the rotating head 24, the rotating head 24, which is a delicate precision component, will not be damaged.

Further, the rotation by the rotary cylinder 22 will not be stopped due to increased friction due to contact.

From the moment the rotary head 24 comes into contact with the magnetic stripe 2, the motors 32 and 37 each rotate at a low speed to move the magnetic card l at a slow speed. Since the rotating cylinder 22 is rotating, the rotating head 2
4 sequentially magnetically records information so as to form a helical recording section 5 while sequentially contacting the surface of the magnetic stripe 2 .

When the movement of the magnetic card 1 by a predetermined amount is completed, the tip of the magnetic card 1 reaches the detector 39, and it is detected that recording of information by the rotary head 24 is completed. This detector 3
When the position of the magnetic card 1 is detected by 9, the rotation of the motors 32, 37 is stopped, the movement of the magnetic card 1 is stopped, and then the rotation of the rotating cylinder 22 is stopped. and,
At the same time, the motor 46 reverses and slides the slider 47 by the screw rod 51, causing the ron 48 to move in the opposite direction to the direction D.
is pressed to swing the presser body 42 in the direction of separating it from the rotary cylinder 22, and reverse it in the direction F in FIG. 14.

As a result, the pressing of the holding body 42 against the magnetic card l is completed, and the motors 32 and 37 are then reversely rotated, thereby pulling the magnetic card l back in the opposite direction to that described above. Then, after passing through the guide groove X%Y and the guide rail 14, the magnetic card l returns in the direction G in FIG. 14, which is the opposite direction to that described above. FIG. 14 shows the state in which the magnetic card l is ejected after information has been written, and is then transferred while being held between two rollers 12 and 13, and is placed in front of the magnetic card writer/reader 10. It will be released from the insertion port 11 to the outside.

Note that FIG. 15 shows another embodiment of the method for recording information on the magnetic stripe 2. In FIG.

That is, in the first embodiment, the rotary cylinder 2
Each rotary head 24 in No. 2 was provided with a magnetic gap perpendicular to the direction of rotation. However, in this embodiment, among the four rotary heads 24 attached to the rotary cylinder 22, the inclination angle of the gap between adjacent rotary heads 24 is changed.
It is possible to perform so-called azimuth recording on adjacent trunks P and Q, which are recorded in sequence, so that the magnetic recording directions do not interfere with each other. By performing this azimuth recording, the proximity of adjacent trunks P and Q can be made extremely high, and the degree of integration of all tracks in the magnetic stripe 2 can be increased. This allows the amount of information to be recorded to be extremely high.

〔Effect of the invention〕

Since the present invention is configured as described above, when the rotary head is brought into contact with the magnetic stripe attached to a thin and flexible magnetic card, in order to bend the stiff magnetic card at a predetermined curvature, the holding body is used to bias the magnetic card. However, the force applied from the back of the magnetic card is not directly transmitted to the rotating head, and the magnetic stripe can be brought into contact with the rotating head by the elastic force generated by the deformation of the magnetic card. Therefore, the magnetic stripe and the rotating head can always come into contact with each other due to the elastic force of the 611 card without any excessive force being applied to the rotating head by the holding body, so that reading and writing of information can be performed reliably. Further, since no excessive force is applied to the rotating head, it is possible to prevent damage or malfunctions.
