Abstract

PURPOSE:To prevent the wear of a magnetic head by operating the supporting mechanism bringing a magnetic head and magnetic recording card into contact by pressing the back face of a magnetic card in the case of reading or writing. CONSTITUTION:At the time of reading or writing the screw lever 51 rotated by a motor 46 moves a slider 47 along a slider guide 45 in a direction D. The pressing face 58 of a pressing body 42 is brought into contact with the back face of a magnetic card 1 and helps from the back face so that a rotary head 24 may surely be brought into contact with the magnetic stripe of the card 1. On the other hand, when a reading or writing is completed, the screw lever 51 is rotated in the reverse direction, the slider 47 and a rod 48 are pushed up and the pressing body 42 is rotated in the reverse direction with a shaft 41 as the center against the elastic force of a spring 50. The pressing face 58 of the pressing body 42 is therefore apart from the back face of the card 1 to release the card 1 coming into contact with a rotating cylinder.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic card information recording device that records information on a magnetic card, and in particular, presses the back of the magnetic card in accordance with the moving position of the magnetic card, The present invention relates to a control mechanism in a magnetic recording device that can bring a magnetic head and a magnetic recording band into contact.

[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 in bank cards that allow you to withdraw cash deposited at a bank, as well as cash cards that allow you to withdraw cash from banks. Also, a telephone usage card that allows you to call at a public phone 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 within the amount you have paid. 2. Description of the Related Art Prepaid cards, such as coupon cards that allow you to ride a train or a lotus bus, are being widely used.

Furthermore, depending on the purpose of use, there are entrance permit cards that record a specific signal or code and open a door or gate when the recorded content matches the set recorded content.
It has also been widely applied to POS cards, which can be attached to product price tags in advance to record which products were sold and when each 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. The magnetic stripe 2 shown in FIG. 2 schematically shows the state in which the magnetic recording has been completed, and a magnetization pattern is formed in the magnetic stripe 2 as a parallel recording section 3 in a direction perpendicular to the conveying direction. The information can be read only 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, in the case specified by the JIS standard, the card 1 can only record a maximum of 72 characters, and the capacity 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 had 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 on and reading information from laser cards require extremely high accuracy and have the disadvantage 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 coated on 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, and the amount of information recorded It is possible to greatly increase the number of cards, and the manufacturing cost of the card itself can be reduced. However, when the magnetic card is caused to travel and the rotating magnetic head is brought into contact with the magnetic card in an oblique direction, it is necessary to improve the contact between the magnetic stripe of the magnetic card and the magnetic head. For this reason, a pad must be provided on the back of the magnetic card to hold the magnetic stripe and the magnetic head in constant contact with each other with constant pressure.

However, if the magnetic head and the magnetic stripe were to be in close contact with each other at all times, the magnetic stripe and the magnetic head would come into contact even when the magnetic card was being moved unnecessarily, causing wear on the magnetic head. Therefore, the contact between the magnetic stripe and the magnetic head must be made only when reading or writing is necessary.

[Means for Solving the Problems] In view of the above-mentioned drawbacks, the present invention provides information recording on 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. The apparatus is provided with a duplicate position detecting means in the direction of travel of the magnetic card, and according to the position of the magnetic card detected by this detecting means, the back of the magnetic card is pressed during reading or writing to cause the magnetic head and magnetic recording band to be separated. The present invention provides a control mechanism in a magnetic card information recording method characterized by operating a supporting mechanism that is brought into contact with the magnetic card.

[Effect]

In the present invention, a plurality of position detection means are provided with respect to the running direction of the magnetic card, the position of the magnetic card is determined by the position detection means, and the rotating magnetic head and the magnetic stripe are brought into contact with each other. the support mechanism is operated only when the write or read operation is performed by
Pressure is applied from the back of the magnetic card to bring the magnetic head into contact with the magnetic stripe.

And when simply moving a magnetic card,
The support mechanism is pulled apart to release the contact between the magnetic stripe and the magnetic head, allowing the magnetic card to run freely. Therefore, the magnetic head does not come into contact with the magnetic stripe except when the magnetic head is writing or reading information, thereby preventing wear on the magnetic head.

A count circuit 87 is connected to the switch 53 which is turned on and off by the switch 2, and the output of the count circuit 87 is transmitted to the motor control circuit 86.

Next, the operation of this embodiment will be explained.

First, the magnetic card 1 on which information is to be recorded is inserted into the insertion slot 11 from direction C in the state shown in FIG. 4 or FIG. Then, after the magnetic card 1 is inserted through the insertion slot 11, the light from the lamp 70 is blocked. Then, the light is blocked from the light receiving self 5, and the position detection circuit 80 detects the CP.
It is detected that the magnetic card 1 is inserted into U81. Therefore, the CPU 81 causes the motor 18 to rotate in the forward direction via the motor control circuit 82, thereby rotating the rollers 12 and 13. Therefore, the magnetic card 1 held between the rollers 12 and 13 moves so as to be drawn into the inside of the magnetic card writer/reader 10.

The magnetic card moved by these two rollers 12.13■
is transported further to the back and reaches the guide rail 14. Then, the state shown in FIG. 13 is reached, and the light from the lamp 71 provided at the tip of the guide rail 14 is blocked, and the light is blocked from the light receiving cell 76, so that the tip of the magnetic card 1 is at the position of the opening 33. That is, the light receiving cell 7
6 will be detected. The signal from the light receiving cell 76 is transmitted to the position detection circuit 80, and the motor control circuit 83 causes the motor 32 to rotate in the forward direction at high speed via the CPU 81. Then, the magnetic card 1 transferred by the rollers 12 and 13 is transferred to the helical recording mechanism 15 at high speed by the feed roller 30 driven by the motor 32.
It will be transported in the direction. When transporting the magnetic card 1, the magnetic card 1 is transported while being regulated vertically by the first guide rail 14, and the upper and lower edges of the guide rail 14 are each formed with a guide groove Z bent in a U-shape. Therefore, the magnetic card 1 slides smoothly without shaking vertically.

After passing through the guide groove Z, the magnetic card l will be transferred to the helical recording mechanism 15, but the length between the steps of the lower fixed cylinder 21 and the upper fixed cylinder 23 is the width of the magnetic card l. Moreover, since the top and bottom of this step are covered by guide plates 25 and 26 like eaves, the magnetic car l"
Its upper and lower edges are held in the guide groove X1Y formed at 7.28, and it is inserted while being bent to the radius of curvature of the sliding surface 27.28.

Then, when the magnetic card 1 moves further and the tip of the magnetic card 1 reaches the guide rail 16, the guide rail 16
In this case, the guide piece 61 is inserted between the guide grooves W formed above and below.

When the magnetic card 1 reaches the inside of the guide rail 16, the magnetic card 1 is held by the guide grooves X and Y and is held in a slightly bent state at a right angle.

Then, the magnetic card 1 is transported by the motor 32 and the feed roller 30, passes through the outer periphery of the rotating cylinder 22 of the helical recording section 15, and is transported to the tip of the second guide rail 16. The tip reaches the opening 38 and blocks the light emitted from the lamp 73,
The light receiving self 8 detects that the leading end of the magnetic card 1 has reached the position of the opening 38. The signal of this light receiving self 8 is detected by the position detection circuit 80, and the CPU 81
The motor control circuit 83 temporarily stops the operation of the motor 32 via the motor control circuit 83.

Thereafter, a signal is transmitted to the motor control circuit 86 to cause the motor 46 to rotate in the forward direction.

Therefore, the screw rod 51 rotated by the motor 46 is
Slide the slider 47 along the slider guide 45 into the 10th position.
It will be moved in the direction of the drawing. For this reason, Rondo 48
moves in the direction D in FIGS. 6 and 10, acts to release the elastic force of the spring 50, and the actuating body 43 is pushed by the spring 50. This operating body 43
As a result of the pushing movement, the presser body 42 is swung in the direction E in FIGS. 6 and 10, and the presser surface 58 of the presser body 42 is
is moved in the direction of the sliding surface 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,
The magnetic card l is regulated to be bent with an accurate radius of curvature, and the rotating head 24 is attached to the magnetic stripe 2 of the magnetic card 1.
from the back to ensure proper contact. 14th
The figure shows a state in which the magnetic card 1 is in contact with the sliding surfaces 27 and 28 and is pressed down from the back side by the presser body 42.

Further, when the threaded rod 51 is rotated by the motor 46 as described above, the cam 52 fixed to the threaded rod 51 turns on and off the switch 53 each time the cam 52 rotates, and the disconnection signal is transmitted to the counting circuit 87. This count circuit 8
7, the amount of movement of the slider 47 screwed into the screw rod 51 is set in advance according to the count amount, so
A counting circuit 87 counts the signal from this switch 53, and when it reaches a predetermined number of times, determines that the slider 45 has moved by a set distance, and transmits the signal to a motor control circuit 86. This motor control circuit 8
6, the motor 4 is activated by the signal from this count circuit 81.
Stop the rotation of 6. Then, the presser body 42 has a spring 50
It is in contact with the back surface of the magnetic card 1 only by the elastic force of , and is in contact with a predetermined contact pressure.

When the movement of the pressing body 42 by the motor 46 is completed, the CPU 81 then controls the motor control circuit 85 to rotate the motor 64 and rotate the rotary cylinder 22 at high speed via the output shaft 65. At the same time, motor control circuit 83.
84 to rotate the motors 32 and 37 in the forward direction at low speeds. That is, the magnetic card 1 is moved at a minute speed while being guided by the guide rails 14.16 and the guide plates 25.26, and at the same time, the magnetic head 24 of the rotating cylinder 22 rotated at high speed by the motor 64 sequentially touches the surface of the magnetic card 1. As a result, information is recorded on the magnetic stripe 24 by the magnetic head 24 in diagonal tracks as shown in FIG.

When the magnetic card 1 is conveyed at low speed by the feed roller 30 and the tension roller 35 driven by the motors 32 and 37, information is sequentially written from the head 24 onto the magnetic stripe. and feed roller 30
The magnetic head transported by the tension roller 35 is gradually transported along its entire length toward the guide rail 16. Then, the leading end of the magnetic card 1 finally reaches the opening 39, and the light from the lamp 74 is blocked and the light receiving self 9 detects that the leading end of the magnetic card 1 has reached the opening 39. When the magnetic card 1 reaches this opening 39, the rear end of the magnetic card is located at the final position where the magnetic head 24 of the rotating cylinder 22 can contact the magnetic stripe 2 over its entire length. Then no more magnetic cards 1
Since information cannot be written on the magnetic stripe 2, writing of information ends.

First, the signal detected by the light receiving self 9 is transmitted to the position detection circuit 80.
is detected and transmitted to the CPU 81. and CPU
81 connects the motor 32.81 via motor control circuits 83.84.
37's low speed forward rotation is stopped.

Therefore, the magnetic card 1 stops at the final position of the write operation and is temporarily held at that position. Next, the CPU 81 transmits a signal to the motor control circuit 86 to rotate the motor 46 in the opposite direction. Then, the screw rod 51 is rotated in the opposite direction to that described above, and the slider 47 and the rond 48 are pushed up.
The presser body 42 is rotated in the opposite direction about the shaft 41 against the elasticity of the spring 50. Therefore, the pressing surface 58 of the pressing body 42 is separated from the back surface of the magnetic card 1,
The magnetic card 1 is released from contact with the rotating cylinder 22. At the same time, the CPU 81 also controls the motor control circuit 8.
5 to temporarily stop the rotation of the motor 64.

When the magnetic card 1 is released from contact with the holding body 42 and the magnetic card 1 is no longer held, the next written information is read and the information is checked. The CPU 81 then controls the motor control circuits 83 and 84 to rotate the motors 32 and 37 at high speed in the opposite direction.

Then, the feed roller 30 and the tension roller 35 rotate at high speed in opposite directions, and the magnetic card slides on the guide rails 14, 15 and the guide grooves X, Y, and is pulled back at high speed in the opposite direction to the above.

When the rear end of the magnetic card 1 reaches the opening 34, the magnetic card 1 blocks the light from the lamp 72, and the light receiving cell 7
7, it is detected that the magnetic card has returned to the opening 34. Then, the output of the light receiving cell 77 is sent to the position detection circuit 80.
The information is transmitted to the CPU 81 via.

Then, the CPU 81 causes the motor control circuits 83 and 84 to temporarily stop the high-speed reverse rotation of the motors 32 and 37, and simultaneously operates the motor control circuits 85 and 86 to control the motor 64.
6 and 10E in the same manner as described above.
direction, and the pressing surface 58 of the pressing body 42 is brought into contact with the magnetic card 1 from the back side.

When the pressing operation of the magnetic card 1 from the back side by the pressing body 42 is completed, the motor control circuit 83.
84 is operated to rotate the motors 32 and 37 at low speed in the forward direction, and the magnetic card 1 is transported at low speed by the feed roller 30 and the tension roller 35. For this reason, the rotating magnetic head 24 reads the information previously written on the magnetic stripe 2 and compares it with the original information stored in a computer or the like to check whether the information is accurately stored.

Note that in reading the information at this time, the feed roller 30
and the tension roller 35 move the magnetic card 1 slightly, and the reading operation starts when the magnetic card 1 accurately reaches the opening 38 again.

This allows the reading start point to be set accurately.

When this reading operation is performed, the magnetic card 1 is sequentially conveyed in the direction of the guide rail 16 in the same manner as the writing operation, and the magnetic head 24 contacts all the tracks to check the written information. Then, the tip of magnetic card 1 is in opening 3
By reaching the position 9 and blocking the light from the lamp 74, the light receiving self 9 detects that the magnetic card 1 has reached the end of writing, and the position detection circuit 80 sends a message to the CPU'81. Sends a signal to stop the reading operation.

Then, the CPU 81 sends a signal to the motor control circuits 83 and 84 to temporarily stop the operation of the motors 32 and 37.

Then, in the same manner as described above, the motor control circuits 85 and 86 are operated to stop the rotation of the motor 64, thereby causing the rotary head 2 to
Stop the rotation operation in step 2. Then, the motor 46 is rotated in the opposite direction by the motor control circuit 86, and the presser body 42 is swung about the shaft 41 in the opposite direction to the above-mentioned direction against the spring 50, thereby releasing the contact between the presser body 42 and the magnetic card 1. do. When the contact between the magnetic card 1 and the presser body 42 is released in this way, the magnetic card 1 can be freely transferred.

Next, the CPU 81 controls the motor control circuits 83 and 84,
The motors 32, 37 will be rotated at high speed in the opposite direction. Then, the feed roller 30 and the tension roller 35 rotate at high speed in opposite directions, and the magnetic card 1 slides on the guide rail 14, 16 and the guide grooves X and Y, and is sent out at high speed in the opposite direction to the insertion direction. It turns out. At this time, since the CPU 81 similarly rotates the motor 18 in the opposite direction at high speed via the motor control circuit 82, the rollers 12 and 13 move the magnetic card 1 pushed out from the guide rail 14 into a magnetic card writing position. The material is conveyed so as to be released outside of the reader 10.

FIG. 15 shows a state in which the magnetic card 1 is being held between the rollers 12 and 13 and being transported in the opposite direction G direction.

When the magnetic card 1 is ejected from the insertion slot 11 of the magnetic card writer/reader 10 by the rollers 12 and 13, the magnetic card 1 temporarily blocks the light from the lamp 70, preventing the magnetic card 1 from passing through the light receiving self 5. Let me know what happened. Therefore, the light receiving self 5 is connected to the CPU 8 via the position detection circuit 80.
1 is informed that ejection of the magnetic card 1 has been completed and the operation has ended. For this reason, the CPU 81 controls the motor control circuit 83.
84 is stopped, each operation of motors 18, 32, and 37 is stopped, and the initial state is restored. Then, it waits for the next write operation by inserting the magnetic card 1.

Note that FIG. 17 is a flowchart showing the order of operations in this embodiment.

Further, FIG. 16 shows another embodiment of the method of 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 by recording on adjacent tracks P and Q, which are sequentially recorded, so that the magnetic recording directions do not interfere with each other. 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 2 can be increased, 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, when information is recorded on a magnetic stripe attached to a thin and flexible magnetic card, the mechanism for bringing the magnetic card into contact with the magnetic head can be operated depending on the position of the magnetic stripe. In addition, when there is no need to write information, the contact between the magnetic stripe and the magnetic head is released, and wear of the magnetic head can be prevented.
