Abstract

PURPOSE:To record numerous information on a magnetic card by bending the shorter side of the magnetic card into an arc and bringing a rotating magnetic head into contact with its inside and relatively moving the card in the direction of the longer side. CONSTITUTION:When a magnetic card 4 is inserted to a reader/writer, rolls 31-34 of a clipping mechanism 20 are rotated by a motor 39 to carry the card 4 to a prescribed position. Next, a head pad 70 of a pad mechanism 22 is driven by a motor 69 and is moved to bend the shorter side of the card 4 into an arc. A rotating drum 51 is brought into contact with its inside and a head block 47 is linearly moved in the direction of a screw 48 by a motor 49 to record information. As the result, many tracks are successively formed on a stripe 5 of the card 4 in parallel to form an orthogonal scanning recording part 6. Thus, numerous information is recorded on the card 4.

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, and in particular to a magnetic card information recording device that records information on a magnetic card, and particularly to a magnetic card information recording device that records information on a magnetic card. The present invention relates to an information recording device for a magnetic card that can be improved in quality.

[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 offers such as credit cards, and cash cards that allow you to withdraw cash from banks. Also, a telephone usage card that allows you to call at a public telephone within the amount you have paid in advance, 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 issue a ticket with a fare within the amount you have paid in advance, or a ticket issuing card that allows you to issue a ticket with a fare within the amount you have paid in advance. 2. Description of the Related Art Prepaid cards, such as coupon cards that allow you to ride trains or buses, have been 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.

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, and the fixed magnetic head is brought into contact with the surface of the moving magnetic stripe 2, and information is recorded on the magnetic stripe 2 as a magnetic change according to a conventionally well-known theory.

FIG. 2 schematically shows the state in which magnetic recording has been completed on the magnetic stripe 2 by this conventional method. On this magnetic stripe 2, a magnetization pattern is formed in parallel in a direction perpendicular to the direction of conveyance as a parallel recording section 3, and by conveying the magnetic head along the direction of arrow A in which the magnetic card 1 is conveyed, information is stored. It is possible to read it.

However, when information is recorded on the magnetic card 1 using the conventional recording method, the information is magnetically recorded only when the magnetic head is fixed and the magnetic card 1 is moved. For this reason, conventional magnetic cards 1 can only record a maximum of 72 characters under the JIS standard, for example, and the amount of information that can be recorded is extremely limited.

Because of these shortcomings, in recent years there have been new technologies that record a large amount of information on a thin card-shaped carrier called an IC card that has a built-in high-density integrated circuit, or that record a large amount of information optically using laser light. Something called a laser card has also been developed. However, IC cards have the disadvantage that they are expensive, and the contacts for inputting and outputting data must be processed with high precision. 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 precision 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, the long side of the magnetic card is bent and the magnetic stripe is placed inside, and a magnetic head that rotates in a helical manner is attached to the magnetic stripe. It records information.

In this method, a large number of trunks are formed diagonally to the direction in which the magnetic card advances, and information is recorded in each trunk in sequence, making it possible to extremely increase the amount of information recorded. .

However, in this method, the rotating magnetic head must be tilted diagonally to the running direction of the magnetic card to scan, so the rotating head must be set with its axis tilted to the running direction of the magnetic card. It was something that should not have happened. For this reason, extremely high precision is required to set the angle between the axis of the rotating magnetic head and the direction in which the magnetic card runs.

[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. Hold the magnetic card with the short side bent into an arc shape, position the rotating magnetic head inside the bent magnetic card, and place the magnetic card and the rotating magnetic head relative to each other in the direction of the long side of the magnetic card. The present invention provides an information recording device for a magnetic card, which is characterized in that information is recorded on a magnetic recording band by moving the card vertically.

[Effect]

In the present invention, the short side of the magnetic card is curved with the magnetic recording band inside, and the rotating magnetic head comes into contact with the inner peripheral surface of the curved magnetic card. For this reason, the magnetic card is bent along its short side, so if the bending accuracy is good, the contact with the rotating magnetic head will be accurate, and the long side of the bent magnetic card will meet the rotating axis of the magnetic head. It only needs to be parallel to the direction, and the accuracy can be easily increased to an extremely high level.

When the magnetic card 4 is bent and comes into contact with the outer periphery of the rotating drum 51, the magnetic stripe 4 has a width such that when one magnetic head 54 ends contact, the other magnetic head 54 starts contact. This is what is set.

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. Then, the magnetic card 4 is held between the pair of rollers 12 and 12 as shown in FIG. 8, and is drawn into the magnetic card writer/reader 10. Then, it is held between rollers 12.12 and 13.13 rotated by the motor 18, and transported further to the back and conveyed in the direction of the holding mechanism 21. This roller 13.13
The magnetic card 4 transported by has its long side surface contacting the inner surface of the frame plate 30 of the clamping mechanism, and the upper and lower surfaces of one side surface are clamped from above and below by rollers 3132, 33, and 34, respectively, The magnetic card 4 is held at one of its long sides and lifted into the air. These rollers 3132, 33, 34 are each rotated by a motor 39, and the magnetic card 4 is rotated by a motor 39.
．． The magnetic card 4 is conveyed while being clamped by the clamping mechanism 33 and 34, and when the magnetic card 4 is conveyed to a predetermined position, the operation of the motor 39 stops, and in this state, the magnetic card 4 is lifted by the clamping mechanism 20 into the space above the right-angle recording mechanism 21. It will be in a state where it is

Magnetic card 4 holds its long side on roller 3L32.33.34
When the motor 6 is lifted up in a cantilevered state,
9 is activated, and the feed screw 68 is rotated. Therefore, the pad block 67 is connected to the guide rod 6 by the feed screw 68.
5.66, and the pad block 67 is moved toward the guide rod 45.4 so that the entire pad block approaches the right angle recording mechanism 21 direction.
6 at right angles. Then pad block 67
The other long side of the magnetic card 4 comes into contact with the curved inner circumferential surface of the head pad 70 that is placed and fixed thereon, and this long side is gradually pushed downward in accordance with the curvature of the head pad 70 . As the head pad 70 approaches further, the other long side of the magnetic card 4 is gradually directed downward, and the entire magnetic card 4 is bent into a shape that matches the outer periphery of the rotating drum 51. When the head pad 70 is finally moved, the other long side of the magnetic card 4 fits into the holding groove 72, and the side surface of one long side contacts the inner wall of the frame plate 30, and this frame plate 30 and the holding groove are brought into contact with each other. 72, the head pad 70 is bent in a shape matching the curvature of the inner circumference of the head pad 70.

The finally bent state of the magnetic card 4 is the state shown by the broken line in FIG. At this time, the central part of the magnetic card 4 is bent to approximately the same degree as the radius of curvature of the rotating drum 51, and the long sides on both sides of the magnetic card 4 are positioned at right angles, and the head pad 70 is bent in its entirety. Since the magnetic card 4 contacts the outer surface of the magnetic card 4, the magnetic card 4 is pressed by the head pad 70 so as to be in close contact with the outer periphery of the rotating drum 51.

At this time, the rotary drum 51 is rotated at high speed by the motor 52, and at the same time, the motor 49 is also driven to drive the feed screw 48.
When the head block 47 is rotated, the guide rod 4
5.46 in a straight line in the H direction in FIG. 8. Therefore, the contact surface of the magnetic head 54 fixed to the outer circumference of the rotating drum 51 is in contact with the surface of the magnetic stripe 5, and one magnetic head 54 forms one track, and the magnetic heads 54 are sequentially moved at an equal pitch. Information can be recorded on the magnetic stripe 5 as magnetic changes by contacting it.

At this time, after one magnetic head 54 comes into contact with the magnetic stripe 5, the other magnetic head 54 starts contacting the magnetic stripe 5 just before the contact ends, and each magnetic head 54 is always in contact with the magnetic stripe 5. state. Since the head block 47 is quietly moved in the H direction by the feed screw 48, the other magnetic heads 54 do not come into contact with the part that one magnetic head 54 has contacted, and the trajectory of the contact made by the magnetic head 54 is in the middle direction of Figure 4,
The scanning of the magnetic stripe 5 by the magnetic head 54 is in the direction D, which is substantially perpendicular to the longitudinal direction of the magnetic card 4, and a perpendicular scanning recording section 6 is formed here.

When the hend block 47 by the motor 49 has finished contacting the magnetic stripe 5 from one end to the other, it is assumed that the writing of information has been completed and the motor 49 stops its operation. Thereafter, the motor 69 is activated, and the pad block 67 is moved by the feed screw 68 in the direction opposite to the above-mentioned F direction, and the magnetic card 4, which had been curved by the head pad 74, is gradually restored to its horizontal position. .

Once the head pad 70 has finished regulating the bending of the magnetic card 4, the motor 39 is activated to rotate the holding rollers 31, 32, 33, and 34 in the opposite direction to the above-mentioned direction to move the magnetic card 4 in the direction of the rollers 13. Convey while cantilevering.

Next, once the magnetic card 4 is held between the upper and lower sides by the rollers 13.12, the magnetic card 4 is conveyed by the rollers 13.12 rotated by the motor 18 in a direction opposite to the above-mentioned E direction, and is inserted into the insertion slot. 11 and is ejected from the magnetic card writing/reading machine 1o.

By repeating this operation, a large amount of information can be written or read on the magnetic stripe 5 of the magnetic card 4 as a right-angle scanning recording section 6.

Next, FIG. 12 shows another method of recording information in the orthogonal scanning recording section 6 according to the present invention.

That is, in the first embodiment, the magnetic gaps of each magnetic head 54 fixed to the rotating drum 51 were positioned at right angles to the rotation direction. However, in this embodiment, adjacent magnetic heads 5 of four magnetic heads 54 attached to the rotating drum 51 are
The inclination angles of the magnetic gaps in step 4 are changed, and recording is performed on adjacent tracks P and Q so that the directions of the magnetic recording do not interfere with each other, using so-called azimuth recording. It is possible to do so. By performing this azimuth recording, the proximity of adjacent tracks P and Q can be made extremely high, and the degree of integration of all tracks in the magnetic stripe 5 can be increased, so that the information capacity to be recorded can be extremely increased. It is something that can be done.

In this embodiment, the magnetic card 4 is bent and fixed by the head pad 70, and the rotating magnetic head is moved in the length direction of the magnetic card 4. However, the rotating magnetic head is not limited to this embodiment. It goes without saying that the same effect can be obtained by fixing the head at that position and bringing the magnetic card 4 bent by the head pad into contact with it while conveying it in its length direction.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to record an extremely large amount of information on a magnetic card, which conventionally could not record a large amount of information. In addition, in this case, the short side of the magnetic card is bent and the magnetic head is rotated on the bent inner peripheral surface, so the axis of rotation of the magnetic head and the direction of transport of the magnetic stripe are aligned as in a helical recording mechanism. There is no need for tilting, and accuracy can be improved very easily.
