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 cleaning mechanism in a magnetic card information recording device that can remove dirt, dust, oil, and the like.

[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 deposited at a bank using the card. 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 trains or buses, have been widely used.

Furthermore, depending on the purpose of use, there may be entrance permit cards that record a specific signal or code and open a door or gate when the recorded content matches a preset 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 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 held in place with a belt etc.
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 conveyance direction. The information can be read only along the six directions of arrows 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. In the case of the card 1, for example, according to the current JIS standard, only a maximum of 72 characters can be recorded, and the capacity of information that can be recorded is extremely limited.

Due to these shortcomings, in recent years, there have been systems 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 to and reading information from laser cards require extremely high accuracy and have the drawback of being extremely expensive.

A new recording method has been developed to solve these conventional drawbacks and record a large amount of information at low cost. It's been Xed. 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, in this method of recording high-density information on the magnetic stripe of a magnetic card in multiple trunks, it is necessary to maintain good contact between the magnetic head and the magnetic stripe. Any failure to write or read is an information error. In addition, with magnetic cards carried by people, oil and fat generated from the human body adhere to the magnetic stripe.
When this oil and fat comes into contact with the magnetic head, it causes damage to the magnetic head and information errors, and the oil and fat accumulates on the magnetic head, causing failure.

[Means for solving problems]

In view of the above-mentioned drawbacks, the present invention uses a magnetic card in which a magnetic recording band is provided on a thin, flat carrier, and in an information recording device for a magnetic card that can record information, magnetic recording is performed at a position before the magnetic card comes into contact with the magnetic card. The present invention provides a cleaning mechanism for a magnetic card information recording device, characterized in that it is provided with a cleaning means for removing impurities adhering to the band.

[Operation] In the present invention, a magnetic card inserted into the magnetic card information recording device passes through a contact member fixed at a slightly right angle to the direction of movement of the magnetic card.

This contact member is elongated and elastic, and the surface of the magnetic stripe comes into contact with the tip of the elastic member bent into an arc shape. Then, due to the elasticity of this contact member, the tip of the contact member always comes into contact with the magnetic stripe while moving with some pressure, and impurities such as dirt, dust, oil, etc. that adhere to the surface of the magnetic stripe are removed by the elastic member. It will be scraped off at the tip. Therefore, when the rotating magnetic head comes into contact with the magnetic stripe in the next step, the clean surface of the contact member after impurities has been removed will come into contact with it, ensuring that information is written and read reliably. This prevents dirt, dust, oil, etc. from adhering to the magnetic card, thereby preventing malfunctions.

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, the magnetic card l is held between the rollers 12 as shown in FIG. It will be drawn into the inside of IO. This motor 74 rotates through an output shaft 75 and a pulley 76.
Boo 1J72.73 via belt 77, shaft 70.71
Since the two pulleys 12 and 13 are rotated in the same direction and at the same rotation speed, the magnetic card l is taken in at a predetermined speed. The magnetic card 1 that has passed between the rollers 12 is sent to the cleaning mechanism 18. The magnetic card 1 is inserted between the pressure roller 81 and the contact members 83 and 84, and while rotating the pressure roller 80, the magnetic card 1 is inserted into the cleaning mechanism 18. The magnetic stripe 2 is brought into contact with the tips of the members 83 and 84 while sliding and moving. At this time, the surface of the magnetic stripe 2 comes into contact with the contact members 83 and 84, but the tip of the contact member 84 has a slight curvature of 4
It is bent into an arc shape of 1/2 of a circle, and its tip W is positioned perpendicular to the surface of the magnetic stripe 2, so the edge-shaped tip is in elastic contact with the surface of the magnetic stripe 2, so this contact member Dirt and dust adhering to the surface of the magnetic stripe 2, as well as oil and fat adhering from the surface of the finger, are scraped off to the end cross section W of 84. When the magnetic card 1 is further taken in, it is held between the two rollers 13, transported further back, and then inserted into the inside of the first guide rail 14. When the magnetic card 1 is inserted into the guide rail 14, the upper and lower edges of the magnetic card 1 are inserted into the guide grooves Z 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, making it possible to slide the magnetic card 1 further inward.

After passing through the guide groove 2, the magnetic card 1 is transferred to the helical recording mechanism 15. Moreover, since the top and bottom of this stepped part are covered like eaves by guide plates 25 and 26, the magnetic card l is placed on this sliding surface 27 and 28.
The upper and lower edges are held in the guide grooves X and Y formed in the
It will be inserted while being bent to the radius of curvature of the sliding surfaces 27 and 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 feed roller 35, but since the feed roller 35 is rotated by the motor 37, the magnetic card 1 is held in the guide grooves X and Y. In this state, it is bent slightly at right angles and can be moved freely by the two feed rollers 30 and 35. At this time, the tip of the magnetic card 1 is detected by the detector 38, and the state in which the magnetic card 1 is completely held on the sliding surfaces 27, 28 is detected.

When the position of the magnetic card 1 is detected by the detector 38, 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. It turns out.

Therefore, the iron 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, swinging the presser body 42 in the E direction in FIG. 6, and moving the presser surface 58 of the presser body 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 l, and prevents the magnetic card 1 from being bent with an accurate radius of curvature, and also ensures that the rotating head 24 touches the magnetic stripe 2 of the magnetic card 1. Assisting from the back to make contact. FIG. 12 shows that the magnetic card 1 is in contact with the sliding surfaces 27 and 28, and the presser body 4 is
This shows the state of being pressed by 2.

In this state, the □ motors 32 and 37 each rotate at a low speed, and the amount of movement of the magnetic card I changes to move at a slow speed. Since the rotary cylinder 22 is rotating, the rotary head 24 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 card 1 is completed, the tip of the magnetic card 1 is placed on the detector 3.
9, and it is detected that recording of information by the rotary head 24 has ended. When the position of the magnetic card l is detected by this detector 39, the rotation of the rotary cylinder 22 is stopped, and at the same time, the motor 46 is reversed and slides the slider 47 by the threaded rod 51, opposite to the direction D mentioned above. Push the iron 48 in the direction to swing the holding body 42 away from the rotary cylinder 22, and reverse it in the F direction in FIG. 13. Therefore, the holding body 4 for the magnetic card l
2 is completed, and then the motors 32 and 37 are reversed, thereby pulling the magnetic card 1 back in the opposite direction to that described above. After passing through the guide grooves X and Y and the guide rail 14, the magnetic card l returns in the direction G in FIG. 13, which is the opposite direction to that described above. In FIG. 13, when the magnetic card 1 on which information has been written is reversely fed in the direction of arrow G, the aforementioned motor 74 rotates in the reverse direction, and the magnetic card 1 held between the pair of rollers 13 is pulled out from the guide rail 14. Then, the magnetic card l is inserted between the pressing roller 81 and the contact members 83 and 84. At this time, the pressure roller 81 and the contact members 83 and 84 are in contact with a predetermined pressure from both sides of the magnetic card, and the tip of the contact member 83 is bent into an arc of about a quarter of the circle. , the surface V at its tip
is positioned almost perpendicular to the surface of the magnetic stripe 2, so its tip edge slides while contacting the surface of the magnetic stripe 2, removing dirt, dust, oil, etc. attached to the surface of the magnetic stripe 2. will be stripped off. After the surface of the magnetic stripe 2 has been removed by the contact member 83, it is then held between the rollers 12 and sent out in the direction of arrow G, and is placed on the front surface of the magnetic card reader/writer 10. It is sent out to the outside from a certain discharge port 11.

Note that FIG. 14 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 rotating heads 24 attached to the rotating cylinder 22, the angle of inclination of the gap between the rods 24 is changed between adjacent rotating heads.
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 writing information at high density on the magnetic stripe that is coated on the surface of a magnetic card, or when reading information already written at high density, the writing or Before the reading operation, dirt, dust, or oil transferred from the human body is removed from the surface of the magnetic stripe, ensuring that the magnetic head contacts the surface of the magnetic stripe without coming into contact with these impurities. Therefore, reading and writing errors will not occur. In addition, since impurities are removed before the magnetic head and magnetic stripe come into contact, these impurities do not come into contact with the magnetic head, which rotates at high speed, and the magnetic head is free from dust, oil, etc. even after long-term use. without wearing it,
This can prevent the occurrence of malfunctions, etc.
