Abstract

PURPOSE:To record many information and to improve the precision of recording and reproducing by bending the longer side of a magnetic card and bringing a rotating magnetic head into contact with its inside and moving the head in the direction of the shorter side of the card. CONSTITUTION:When a magnetic card 4 is inserted to a reader/writer so that a magnetic stripe 5 is on the inside, the card 4 is carried to a prescribed position by a guide mechanism 20. Next, a bent retaining body 63 of a pad mechanism 22 is driven in the direction of an arrow G by a motor 52 to bend the longer side of the card 4 into an arc. A rotating drum 46 is brought into contact with its inside and the drum 46 is relatively moved in the direction of the shorter side of the card by a motor 44 to record information. As the result, plural tracks are successively formed on the stripe in parallel to record many information, and the axis of rotation of the head and the direction of the shorter side of the card are allowed to coincide with each other to improve the precision of recording and reproducing very much.

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 for recording information on a magnetic card. An information recording device for a magnetic card that can improve the accuracy of contact between a magnetic recording band and a magnetic head by bringing a rotating magnetic head into contact with the inside of a magnetic card that is bent and curved.

[Conventional technology]

Magnetic cards (thin plastic or paper carriers with magnetic stripes pasted on the surface) have been widely used for some time, and for example, they can be used to purchase goods or provide services within a predetermined credit balance instead of cash. It is often used for credit cards that allow you to receive cash from banks, and cash cards that allow you to withdraw cash deposited at a bank. A telephone usage card that allows you to use the telephone, a ticket issuing card that allows you to issue a ticket with a fare within the amount you have paid in advance, or a number of times you can ride a train or pass within the amount that you have paid. 2. Description of the Related Art Prepaid cards such as ticket cards are being widely used.

Furthermore, depending on the purpose of use, a specific signal or code may be recorded and attached to an entry permit card that opens a door or gate when the recorded content matches a preset recorded content, or to a price tag of a product. It has also been widely applied to POS cards that can record which products were sold and when each time a product was sold. Although their purpose of use is different, the essential act of attaching or coating a magnetic stripe to a card-shaped carrier and magnetically recording information on the magnetic stripe is the same.

FIG. 1 shows the appearance of a conventional magnetic card 1.
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. FIG. 2 schematically shows a state in which the magnetic recording has been completed on the magnetic stripe 2. A magnetization pattern is formed on the magnetic stripe 2 as a parallel recording section 3 in a direction perpendicular to the direction of conveyance. Information can be read by moving the magnetic head along the direction of arrow A in which the magnetic card 1 is conveyed.

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 magnetic card 1 is transported. For example, J
When recording according to the IS standard, only a maximum of 72 characters can be recorded, and the amount of information that can be recorded is 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, I.C.
Cards are expensive, and the contacts for inputting and outputting data must be processed with high precision.
It has the disadvantage of being expensive. It also had a characteristic of being extremely weak against static electricity.

Next, laser cards 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 information 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 information is sequentially recorded on tracks diagonal to the direction in which the magnetic card travels, reducing the amount of information recorded. It is possible to make a large number of cards, and the manufacturing cost of the card itself can be reduced.

However, when recording with this method, the direction of conveyance of the magnetic card and the axis of the rotating magnetic head must be tilted at a certain angle, making it extremely difficult to adjust the conveyance of the card and the axis of the rotating head in a writer/reader. This required high precision.

[Means for solving problems]

In view of the above-mentioned drawbacks, the present invention provides an information recording device for a magnetic card that uses a magnetic card in which a magnetic recording band is provided on a thin flat carrier and that can record information using a rotating magnetic head. A magnetic card characterized in that the long side of the magnetic card is curved, and information is recorded by moving a magnetic head rotating inside the magnetic card relatively along the short side direction of the magnetic card. The present invention provides a card information recording device.

[Effect]

In the present invention, a magnetic card inserted into a magnetic card information recording device is curved along the long side of the magnetic card with the magnetic stripe on the inside, and a rotating magnetic head contacts the inside of the curved magnetic card. The magnetic cart moves relatively along the length of the short side of the magnetic cart. For this reason, information is recorded by the magnetic head on multiple tracks in the magnetic stripe, and if the direction of the short side of the magnetic stripe and the axial direction of the rotating magnetic head are made parallel, the position of the magnetic head in contact with the track is relative to the magnetic stripe. It is possible to improve the accuracy. Furthermore, since the structure is simple, manufacturing is easy.

A large drum hole 45 is formed on the top and side surfaces of the head block, and inside the drum hole 45 is a rotating drum 46 with a magnetic head fixed to its outer periphery, and a rotary drum 46 for rotating the rotating drum 46. A motor 47 is inserted.

Note that the outer periphery of the rotating drum 46 is formed by the pair of sliding grooves 32,
It is positioned so that it forms a curved surface that is almost the same as the curved surface formed by 33.

FIG. 9 shows the configuration of the rotating drum 46 in the head block 42. The rotating drum 46 has a groove formed on its outer periphery, and within this groove, magnetic heads 48 are installed at four locations on the outer periphery. It is installation. The arrangement of this magnetic head 48 is shown in FIG.

The magnetic heads 48 provided on the outer periphery of the rotating drum 46 are positioned 90 degrees apart from each other about the central axis of rotation. Further, the length of the outer circumference of each rotary head 48 is set to be slightly narrower than the width of the magnetic stripe 5. Also, the position of the head block 42 and the guide rail 30 when viewed from the front of the belly button 42.
．． The relative position of 31 is shown in FIG.

Next, the pad mechanism 22 will be explained. The driving portion of the pad mechanism 22 is constituted by a base plate 5o located above the head block 42 and fixed thereto. A slider guide 51 made of a board bent into a U-shape is fixed to the tip of the base 50.
A motor 52 is fixed at the rear. A slider 53 that can slide in the length direction is slidably inserted into the slider guide 51.
A screw rod 54 rotated by a motor 52 is screwed into the screw rod 3 .

A cam 55 is fixed to the outer periphery of this threaded rod 54, and this cam 55 turns on and off a switch 56 fixed on the base plate 50.

Further, a rod 57 is fixed in front of the slider 53 in the sliding direction.

Next, a shaft 58 is provided in front of this base 50, and this shaft 58 is rotatably held by shaft support plates 59.60 at both ends, and each shaft support plate 59.6o is supported by a spring 61, respectively. .62 so as to be biased towards the base 50. A presser body 63 whose entire shape is curved is fixed to the center of the shaft 58. This presser body 63 is formed in a curved shape so that its lower part is semicircular and is formed as a presser surface 64. For example, it is integrally molded from plastic or aluminum, and has a shaft 58 as its center. As the presser body 63 swings, the presser surface 64 is positioned so as to approach and separate from the outer periphery of the rotating drum 46.

Next, the operation of this embodiment will be explained.

First, the magnetic card 4 on which information is to be recorded is inserted into the insertion slot 11 from the E direction in the state shown in FIG. 5 or 6. The magnetic card 4 is then held between the pair of rollers 12 and 13 and drawn into the magnetic card reader/writer 10.

The magnetic card 4 taken in by the rollers 12, 13 is further transferred to the back, and both long sides of the magnetic card 4 are inserted into the sliding grooves 32, 33 of the guide rails 30, 31, respectively. Therefore, the magnetic card 4 has sliding grooves 32 and 33.
The transport direction is gradually changed so that the transport direction is guided by the transporter and the transport direction is concavely bent downward. The direction of the magnetic card 4 is changed to approximately 90 degrees by this guide rail 30.31, and the tip of the magnetic card 4, which is curved into a semicircle near the center, is finally located below the lower end of the guide rail 30.31. and magnetic card 4
Both sides of the leading end of are clamped by tension rollers 34 and 35. This state is the state shown in FIG.

and this roller 12, 13, and the tension roller 34
．． When both ends are held at 35, a sensor (not shown) acts, and the rollers 12 and 13 and the tension roller 3
4. The motor driving 35 stops.

Thereafter, the motor 52 is activated and the screw rod 54 rotates, so that the slider 53 slides in the slider guide 51 according to the pitch of the screw rod 54, and in the F direction in FIGS. 7, 8, and 12. will be moved to. Therefore, the rod 57 similarly moves in the F direction, the large diameter portion 66 pushes the spring 68, and the actuating body 65 is pushed by the pressure of the spring 68. Then, the actuating body 65 and the presser body 63 swing in the direction G in the figure around the shaft 58,
The pressing surface 64 of the pressing body 63 comes into contact with the back surface of the magnetic card 4, and the magnetic cart 4 is not lifted up and the rotation 1・ram 63
regulated to match the rotating outer diameter of. Therefore, the magnetic card 4 whose back side is pressed by the presser body 64 is curved in the shape of a quarter arc at its central portion, that is, the portion where the magnetic stripe 5 is located, and its inner circumferential surface is curved around the outer circumference of the rotating drum 46. It is biased so that it comes into close contact with the

When the aforementioned presser body 63 is operating, the motor 47 is operated at the same time, and the rotating drum 46 is rotated at high speed. Therefore, when the magnetic stripe 5 comes into contact with the rotating drum 46, the magnetic heads 48 fixed on the outer periphery of the rotating drum 46 sequentially move the magnetic stripe 5 into contact with the rotating drum 46.
, and a contact locus is drawn sequentially from one side of the magnetic stripe 5 to the other side. At this time, each time an information signal to be recorded is transmitted to the magnetic head 48, information can be recorded in one trunk by one magnetic head 48 in a direction slightly perpendicular to the length direction of the short side of the magnetic stripe 5. can.

At this time, the motor 44 is activated and the feed screw 43 is rotated, so the head block 42 is slowly transferred in the length direction of the guide rod 40.41, and the rotating drum 46 is moved along one long side of the magnetic stripe 5. It will move more slowly toward the other long side in the direction shown by C in FIG. For this reason, after one magnetic head F-48 makes contact, when the next magnetic head 48 makes contact, the position of the contact is shifted, and information is not recorded overlappingly on the same track. Therefore, on the surface of the magnetic stripe 5, there is a fourth
As shown in the figure, information is recorded in a pattern that is almost perpendicular to direction D, which is slightly perpendicular to direction C, which is the direction in which the rotary drum 46 is transported, and a perpendicular recording section 6 is formed.

When the head block 42 moves from one end of the magnetic card 4 to the other end by the rotation of the feed screw 43 by the motor 44 and the recording of information by the magnetic head 48 is completed, the head block 42 is slowly moved by the motor 44. The transfer is completed, and at the same time, the rotation of the rotary tram 46 by the motor 47 is also stopped.

Next, the motor 52 is reversely rotated, the threaded rod 54 is rotated in the opposite direction to that described above, and the slider 53 is moved along the length direction of the slider guide 52 in the direction F in FIGS. 7 and 8. moves in the opposite direction. Therefore, the large diameter portion 67 is caught on the rear part of the actuating body 65, causing the actuating body 65 to rotate the presser body 63 about the shaft 58 in the direction opposite to the direction G in FIGS. 6 and 8. The contact of the magnetic card 4 by the pressing surface 64 is released. Therefore, the magnetic card 4 is released from its curved and pressed state from the rear.

Then, the rear feed roller 12, 13, the tension roller 3
4. By rotating 35, magnetic card 4 becomes 01
Contrary to the above, it moves upward along the sliding grooves 32 and 33,
The magnetic card 4 is ejected from the insertion slot 11 to the outside of the magnetic card writer/reader.

Through these series of operations, a large amount of information is written on the magnetic stripe 5 of the magnetic card 4 in tracks that are slightly perpendicular to the short side from one long side to the other long side.

Note that FIG. 13 shows another embodiment of the method for recording information on the magnetic stripe 5. In FIG.

That is, in the embodiment shown in FIG. 4, each magnetic head 48 fixed to the rotating drum 46 was provided with a magnetic gap perpendicular to the direction of rotation. However, in this embodiment, among the four magnetic heads 48 attached to the rotary drum 46, the inclination angle of the gap between adjacent magnetic heads 48 is changed, so that adjacent tracks recorded in sequence are It is possible to record in P and Q so that the directions of magnetic recording do not interfere with each other, so-called azimuth recording. By recording information using this azimuth recording, it is possible to extremely increase the proximity of adjacent tracks PXQ, and it is possible to increase the degree of integration of all tracks falling on the magnetic stripe 4, so the information capacity to be recorded can be extremely increased. It is something that can be done.

〔Effect of the invention〕

Since the present invention is configured as described above, the magnetic card can be curved along its long sides, and information can be recorded using a magnetic head that rotates on the curved inner peripheral surface.

Therefore, if the axial direction of the rotating shaft of the rotating magnetic head and the length direction of the short side of the curved magnetic card match, information can be written and read accurately on the track, which is a simple configuration. However, it is easy to improve accuracy.
