The purpose of the present invention is to provide a magnetic card recording/reproducing device having a conveyance means capable of stable conveyance, and a magnetic card passed through the device. A magnetic card having a concave portion on the side has a conveying means that rotates while pressing the magnetic card to move it inside the recording/reproducing device, and the magnetic card pressing surface of the conveying means has a concave portion or a concave portion on the surface of the magnetic card. This is a configuration in which recording and reproduction is performed by a recording and reproduction device provided with a through hole or a protrusion that engages with the unevenness of the side surface.

[Industrial application field]

The present invention relates to a magnetic card and a magnetic recording/reproducing device thereof.

Magnetic card systems, which record and reproduce digital data by moving a card-shaped magnetic recording medium in a fixed direction relative to the magnetic head of a recording/reproducing device, are used for credit cards, cash cards, prepaid cards, etc., and do not require carrying cash. It is rapidly becoming popular in general society due to its ease of use, such as the ability to pay fees. With the popularization of such magnetic card systems, various problems are occurring, and in particular, increasing the reliability of recording and reproducing when magnetic card recording and reproducing devices are placed in poor environments has become a problem.

(Prior Art) A typical magnetic card recording/reproducing device takes in an inserted magnetic card, moves it relative to a magnetic head at a predetermined transport speed within the device, reads and writes data, and automatically reads and writes data. For this reason, the recording/reproducing device has a built-in card conveyance means for conveying the inserted magnetic card.This usually consists of a conveyance roller and a pressure roller placed opposite each other, While the magnetic card is held between the facing conveyor belt and the pressing roller with a predetermined pressure, the conveyor roller and the conveyor belt are rotated to convey the magnetic card under the recording/reproducing head at a constant speed, or to take it in and eject it. However, with the popularization of magnetic card systems,
Due to carelessness during storage and handling, magnetic cards often become deformed such as warping, folding, or bending, and dirt, oil, and the like adhere to their front and back surfaces.

If such a deformed or contaminated magnetic card is inserted into a recording/reproducing device, the contact condition and friction coefficient with the rubber rollers and rubber belts of the transport mechanism will deteriorate, especially if the recording/reproducing device is installed outdoors or if oil is present. If a magnetic card is used under poor environmental conditions, such as when a magnetic card is handled with bare hands, the carrying force of the magnetic card will be reduced, causing the magnetic card to slip inside the device, and causing problems in recording and reproducing magnetic data. This may cause errors, or the magnetic card may not be able to be transported (it may become impossible to take it into the device or eject it from the device).

To prevent this, measures such as increasing the diameter of the transport roller, increasing the contact area between the transport belt and the magnetic card, and increasing the contact pressure between the transport means and the magnetic card are taken. are giving.

[Problem to be solved by the invention]

However, with the above-mentioned conventional technology, there are problems such as the external size of the recording/reproducing device becomes larger, the load on the drive motor increases when the card is transported, it is necessary to use a large motor, and this places a burden on the power supply system. was there.

The present invention was created in view of the above-mentioned problems, and includes a magnetic card recording and reproducing device having a conveying means that can stably convey the magnetic card without slipping when the magnetic card is conveyed within the recording and reproducing device, and the present invention. The purpose is to provide suitable magnetic cards.

This is a magnetic card that is used to record data, and has a recess or through hole on the surface other than the magnetic recording area, or a recess on the side parallel to the conveyance direction. The recording/reproducing device has a conveying means that rotates while pressing the inserted magnetic card to move it inside the recording/reproducing device, and the pressing surface of the conveying means has a recess or a through hole on the surface of the magnetic card, or This configuration includes a protrusion that engages with a recess on the side surface.

[For production]

The inserted magnetic card is stably transported without slipping in synchronization with the moving speed of the transport means, as its recess or through hole engages with the protrusion of the transport means of the recording/reproducing device.
Confidence in recording and playback improves.

[Means to solve the problem]

In order to solve the above problems, the magnetic card of the present invention records digital data in the magnetic recording area on the surface. FIG. 3 is a perspective view of the main parts of the second embodiment, and FIG. 3 is a perspective view of the main parts of the third embodiment.

The same reference numerals represent the same objects throughout the figures, and the magnetic card may be a JIS standard magnetic card with a thickness of 0.68 to 0.8 mm, or a thin prepaid card.

In FIG. 1, reference numeral 1 denotes a magnetic card, which is inserted into the recording and reproducing device 2 as indicated by arrow A, and data is recorded and reproduced in a recording area 11 by a magnetic head (not shown) while moving inside the device. A plurality of recesses or through holes 12 are formed along the movement direction on the surface of the magnetic card 1 excluding the magnetic recording area 11.
are formed at a constant pitch. The recording/reproducing device 2 is provided with a plurality of conveyance rollers 21 at intervals smaller than the length of the magnetic card, and the rollers 21 are rotationally driven in a predetermined manner by a drive motor (not shown) built in the drive system housing section 22, a drive force transmission means, etc. be done. A pressure roller 23 is provided opposite to the conveyance roller 21, and is configured to clamp the inserted magnetic card 1 between the conveyance roller 21 and the pressure roller 21 with a predetermined pressing force. The circumference of the conveyance roller 21 is made of rubber, and projections 21a that engage with the recesses or through holes 12 of the magnetic card 1 are formed on the outer periphery at a pitch equal to the pitch of the recesses or through holes.
The magnetic cards are sequentially fitted into recesses or through holes inserted between the pressure roller and the magnetic card to be transported inside the device.

The embodiment shown in FIG. 2 is applied to a recording and reproducing apparatus of a belt conveyance type in which a conveyor belt 25 is suspended between drive rollers 24. Arrow B meshes with gears without slipping
The inserted magnetic card 1 is pressed against the outer peripheral surface of the conveyor belt 24 by the pressing roller 23 and conveyed. On the outer circumferential surface of the conveyor belt 24 (the surface that presses the I card), protrusions 25a that engage with the recesses or through holes 12 of the magnetic card I are formed at the same pitch as the recesses. The inserted magnetic cards l are fitted into the recesses or through holes 12 one after another, and are stably transported without slipping between the magnetic cards and the transport belt. In the case of this belt conveyance method, since the magnetic card is always in contact with the conveyance means, the magnetic card only needs to have four parts or only one through hole.

In the third embodiment shown in FIG. 3, the magnetic card l has a rack-like shape in which a plurality of recesses 13 are formed at a constant pitch on the side surface parallel to the transport direction. Then, in the recording/reproducing device 2, a plurality of pairs of conveyance rollers 26 having rotational axes perpendicular to the surface of the magnetic card 1 transport a part of the cylindrical surface of the magnetic card 1 so as to sandwich the inserted magnetic card on both sides. It is provided so as to sandwich the width direction of a magnetic card inserted into the passageway so as to be exposed. A gear-shaped protrusion 26a is formed on the cylindrical surface of the conveyance roller 26 to engage with the groove 13 on the side surface of the magnetic card.The protrusion engages with the side surface of the inserted magnetic card, and the magnetic card is inserted. It is stably transported without slipping on the transport rollers. Note that a groove is formed on only one side of the magnetic card, a gear-shaped conveyance roller is provided only on the passage side corresponding to that side, and a toothless pressure roller is provided on the opposite side to sandwich the magnetic card in the width direction. You can do it like this.

In this way, in the present invention, recesses, through holes, etc. are provided in locations other than the magnetic recording area of the magnetic card, and protrusions and pins are provided on the surface of the conveying means corresponding to these, and the holes, etc. and the through holes are provided on the surface of the conveying means. By driving the conveyance means while engaging the protrusions or the like, the magnetic card is conveyed without being sagged due to the frictional force between the magnetic card and the conveyance means alone.

As a result, if the card is used in poor environmental conditions for a long period of time, the card contact surface of the recording and reproducing device's conveyance means such as drive rollers and conveyor belts and the surface of the magnetic card become contaminated, reducing the frictional force when driving the card. The card can be transported stably without slipping even when the card is moved, and the reliability of recording and playback can be greatly improved.

These recesses and through holes can be easily formed at the same time as processing the external shape of the magnetic card. It is extremely easy to provide convex portions on the card pressing surface of the conveyance roller or conveyance belt at a pitch corresponding to the concave portions.

As described above, according to the present invention, since frictional force is not used to hold the surface of the magnetic card and the conveyance means, there is no need to increase the clamping force, and the load on the drive motor of the conveyance means does not become excessive. It ends up being In addition, good conveyance is possible without oil or the like adhering to the contact surfaces of rollers or belts or on the surface of the magnetic card and causing slippage.

〔Effect of the invention〕

As explained above, according to the present invention, friction during clamping and conveyance due to deformation of the magnetic card, dust, oil, etc. adhering to the magnetic card or the surface of the conveyance means such as the conveyance rollers and conveyance belts of the recording and reproducing device. Even if the coefficient decreases, the protrusion of the conveying means can engage with the recess of the magnetic card and apply a large conveying force to the magnetic card, achieving good conveyance without slipping of the magnetic card in the recording/reproducing device. It becomes possible to do so.

It is.
