Description

[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) The present invention makes it possible to read, write, and print data on a portable recording medium such as a magnetic card. The present invention relates to a device for reading and writing portable recording media.

(Prior Art) In recent years, flexible thin magnetic cards such as cards for public telephones have become widespread, and applications of this type of magnetic card to a wide range of fields are being considered.

This type of magnetic card will be further explained using a public phone card as an example. Telephone users purchase a card for public telephones in advance, insert the card into a card telephone, and make a call. The card telephone is equipped with a remaining power indicator to inform the telephone user of the remaining power of the card. The remaining power is indicated by a punched hole in the end of the call.

However, while the above-mentioned card phone displays the accurate remaining power on the remaining power display while the phone is in use, the card itself is simply punched with a hole that indicates the approximate remaining power. This was very inconvenient if you wanted to know the exact remaining capacity.

(Problems to be Solved by the Invention) In the conventional portable recording medium reading/N feeding device, punch holes or the like are provided in a magnetic card, which is a portable recording medium, to schematically indicate the magnetically recorded contents. Therefore, it has been desired to display the magnetically recorded contents in more detail to the user. However, when printing is done to display the magnetically recorded contents in more detail, there are cases where the printed contents are rewritten and the magnetically recorded contents are erased, or the magnetically recorded contents are also changed to m8 for unauthorized use.

The present invention has been made based on the above-mentioned problems, and one object is to provide a portable recording medium that can print various data on the surface of the portable recording medium and prevent unauthorized use of the portable recording medium. The object of the present invention is to provide a reading/writing device for reading and writing.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a reading/writing unit that reads and writes data to a portable recording medium; - A printing mechanism unit that prints data to be recorded on the portable recording medium in the writing unit on the portable recording medium using a thermal destruction method.

(Operation) The read/write unit reads recorded data and writes new data to the portable recording medium inserted into the device.

The portable recording medium that has been read and written to is transported to the printing mechanism section, where various data are printed using a heat-sensitive destruction method, and then ejected to the outside of the apparatus.

(Example) Fig. 1 shows the structure of a device/AVA according to the present invention, and Fig. 1 (A) shows the internal structure.
) is a plan view, and li'i1 figure (C) is a left side view. Moreover, FIG. 2 is a J oblique view showing the structure of the magnetic card. .

The device of this embodiment performs magnetic data processing such as reading magnetic data from a magnetic card and picking up data that has been enriched and integrated, and also prints necessary information on the surface of the magnetic card after processing the magnetic data. It is discharged to the outside.

First, the magnetic card of this embodiment will be explained.

As shown in FIG. 2, this magnetic card is a flexible magnetic card, for example -'! 1. The user purchases this card in advance and carries it as a road usage card. Then, each time you use an expressway, it is inserted into the reading/writing device shown in Figure 1 placed at each entrance and exit, and the contents are read. After being checked, the date of use, the exit of the expressway used, the remaining amount, etc. are printed on the front of the card, as shown in Figure 2 (A).

This magnetic card 1 has a magnetic recording area (not shown) in which information is magnetically encoded. This information is then printed on the surface of the magnetic card 1 using a heat-sensitive destruction method.

Furthermore, a magnetic barcode 1B is preprinted on the back side of the magnetic card 1. This magnetic bar food 1
As will be described later, B indicates coded information regarding the rotation of the magnetic head when the data stored in the magnetic recording area of the magnetic/J-do 1 is transferred to and inserted into the magnetic head. It is. Therefore, it goes without saying that the card does not have the magnetic barcode 1B printed on the predetermined force point of the card, but if the magnetic barcode 1B is printed on the predetermined force point, the rotating direction of the magnetic head indicated by this magnetic barcode is If the recording direction of the magnetic data stored in the magnetic recording area does not match, the recorded data cannot be read. Therefore, fraud such as theft or falsification of c1 recorded data can be prevented.

FIG. 3 is a J sectional view showing the internal structure of the magnetic card.

This magnetic IT-board 1 is made by laminating a magnetic layer 83 on one side on a PET resin layer 2 with a thickness of about 200μ, and then a tin layer 4 with a thickness of about 60OA on the magnetic layer 3. , Furthermore, keep it on two tin M4 W! It is constructed by laminating R5.

The magnet 'n3 is composed of gamma iron oxide and barium ferrite, and has a high magnetism of about 2700 (Oe). Further, during printing, the tin layer 4 is melted by heating from a thermal head, and the lower magnetic layer 3 is exposed as shown by the symbol A at the 31st inch, and predetermined printing is performed.

In FIG. 1, the magnetic card 1 inserted through the insertion slot 11 is inserted into the first conveyance row 513 provided in the conveyance path 12. Platen roller 15. Second conveyance roller 17. The third conveyance roller 19 and the fourth conveyance roller 21 convey the sheet to the innermost part of the apparatus.

These rollers 13, 15, 17, 19, and 21 are driven by a belt by a pulse motor (transport motor) 23 via a pulley provided for each roller. Further, each of the conveyance rollers 13, 17, 19 and 21 has a pulse Tanabata 2
The rollers 13, 17, 19, and 21 rotate in the same direction relative to the rollers 13, 17, 19, and 21 due to the reverse rotation of the pulse motor 23.

On the other hand, the platen roller 15 always rotates in the counterclockwise cutting direction in FIG. 1, regardless of whether the pulse motor 23 rotates clockwise or counterclockwise, as will be described later.

Directly above this platen roller 15, a thermal head 25 having a depth 11 approximately equal to the width of the magnetic card 1 is arranged to face the thermal head 25 so as to print on the surface of the transported magnetic card.

Further, a magnetic head 27 is placed directly above the third conveyance roller 19.
is provided to read and write data on the magnetic card.

Further, a magnetic barcode sensor 29 is disposed on the conveyance path 12 at a substantially intermediate position between the 31112nd sending 0-ra 19 and the 4th Wi date sending 0-ra 21, and the magnetic barcode sensor 29 installed on the magnetic card 1 1B can be read.

A first card sensor 35 is disposed on the conveyance path at the end on the insertion slot 1 side, a second card sensor 37 is disposed between the first card sensor 35 and the 11111) feed roller 3, and a second card sensor 37 is disposed between the 21st Jff feed roller 17 and the 21st Jff feed roller 3. There are third and fourth rollers between the third and fourth conveyor rollers 19.
Card hinges 39 and 41 are provided, and a fifth card sensor 43 is provided at the end of the conveyance path 12, respectively.

Each of the card sensors 35, 37, 39, 41 and 43 is composed of a photo sensor consisting of a pair of light emitting/light receiving elements, for example, and when the leading edge of the card or the rear edge of the card is detected, based on the detection signal. Controls such as forward/reverse rotation of the motor and printing timing are executed.

In the conveyance path 12 between the first conveyance roller 13 and the platen roller 15 and between the platen roller 15 and the second conveyance roller 17, a 17th lapper 50 and a 27th lapper 60 for switching the conveyance path of /J-do are provided. has been done.

As shown in FIG. 4, this flapper 50.60 consists of two opposing flapper pieces 51.53 and 6, each having a square cross section.
1.63 are connected with a spacing slightly narrower than the width of the magnetic card.

Each flapper 50 and 60 has stopper pieces 55, 65 on the front panel side. and springs 57, 67.

That is, the first flapper 50 on the insertion port side has its base portion pulled by a spring 57, and is regulated by a stopper piece 55 so that its tip portion is biased upward in the figure. On the other hand, the 27th wrapper 60 on the magnetic head side is
Its base is pulled by a spring 57, and its tip is urged downward in the figure by being restricted by a stopper piece 5). Note that the tension of each spring 57, 67 is preferably large enough to push down or push up the flapper piece by the magnetic card 1 being conveyed.

Therefore, the magnetic card 1 conveyed by the first Wi feed roller 13 faces the gap between the seventeenth flapper 50 and the conveyance path 12, is guided by the flapper 50, and is conveyed to the lower side of the platen roller 15. Then, by counterclockwise rotation of the platen row 515, the second flapper 60 is pushed up and the second
It is guided to the conveyance roller 17.

On the other hand, the magnetic card 1 that has been conveyed to the insertion slot 11 side after the reading and input process of the magnetic card 1 (to be described later) is completed, faces the gap between the second flapper 60 and the conveyance path 12,
0 and is conveyed to the upper side of the platen roller 15. After a predetermined print is made by being held between the platen roller 15 and the thermal head 25, the first flapper 20 is pushed down by the rotation of the platen roller 15, which rotates counterclockwise, and the first WI feed 0-ra 13 is pressed down. It is then discharged from the insertion port 11.

As described above, in this embodiment, when the magnetic card 1 is inserted, the magnetic card 1 is prevented from being conveyed between the linear head 25 and the platen roller 15, and when the card is ejected, the magnetic card 1 is prevented from being conveyed between the linear head 25 and the platen roller 15. It is transported between the thermal head 25 and the platen roller 15. Therefore? JJ It is possible to easily switch the conveyance path without having to set up a complicated mechanism, and the device can be made smaller and simpler.

By the way, as mentioned above, the platen roller 15 is always rotated counterclockwise in FIG. 1.

FIG. 5 is a perspective view of the drive mechanism for the platen roller 15, viewed from the rear side of the apparatus. As shown in the figure, a first pulley 71 for the platen roller and a second pulley 73 for the platen roller disposed outside the 17th pulley 71 are attached to the platen []-ra 15. .

The first pulley 71 for the platen roller is the first pulley 71 for the first conveyance.
Pulley for la 75. It is driven by the pulse motor 23 via the synchro belt 81 passed to the first tension boob 977, motor pulley, . . . , and second conveyance roller pulley 79.

In addition, a second pulley 73 for the platen [coller] is a second tension pulley 83 that is attached to the outside of the first tension pulley 77 and rotates simultaneously with the first tension pulley 977.
It is designed to be driven via a synchro belt 85 that is passed to.

The 11th-li 71 and the 27th-973 of the platen roller 15
Each is equipped with a one-way clutch.

These one-way clutches are provided so that the directions in which they lock the rotating shaft of the platen row 515 are opposite to each other.

Therefore, when driving in the card insertion direction and rotating the synchro belt 81 counterclockwise in the figure,
Second tension pulley 83. The rotational force is transmitted to the second platen roller pulley 73 via the synchronized belt 85, and this No. 27-973 rotates counterclockwise in the figure. The one-way clutch in the second pulley 73 locks the rotation shaft of the platen roller 15. At this time, the first pulley 71 for the platen 1 roller is rotating in the time m direction in the figure via the synchronized belt 81, but the built-in one-way clutch is in a free state, and the rotational force is transmitted to the platen roller 15. Not done. Therefore, the platen roller 15 rotates 1 degree in the counterclockwise direction in the figure, while when the pulse motor 23 reverses and ejects the card, the synchro belt 81 rotates in the clockwise direction in the figure. In driving the second tension 1 pulley 8
3. The second platen roller via the synchro belt 85
Pulley 73 is also rotated clockwise. However, the built-in one-way clutch becomes free, and the rotation shaft of the platen roller 15 is unlocked. At this time, the first pulley 71G for the platen roller rotates in the counterclockwise direction in the figure via the synchro belt 81, and
The internal one-way clutch is in a locked state,
Rotational force is transmitted to the platen roller 15.

Therefore, the platen roller 15 continues to rotate counterclockwise in the figure.

As described above, in this embodiment, the first platen roller pulley 71 and the second pulley 21-973 are equipped with two one-way clutches that lock in different ways (from 1 to 1). Regardless, it will always rotate in the same direction. For this reason, the flapper 50
．． In combination with 60, a card conveyance path switching mechanism can be constructed easily and compactly by using the bridge.

By the way, as mentioned above, the rotation direction of the platen roller 15 is controlled by the pulse motor 13 using the one-way clutch.
If the rotation speed is the same regardless of whether the rotation is forward or backward, so-called "print extension" will occur when the thermal head 25 prints on the magnetic card 1.

That is, when the pulse motor 23 rotates, there is vibration in the rotational direction, and a return occurs in the opposite direction to the rotational direction at each step rotation. For this reason, the rotation in the return direction is superimposed and the rotation of the platen roller 15 is accelerated.If the printing timing of the thermal head 25 is set in synchronization with the rotation of the pulse motor 23, the rotation in the return direction is accelerated. 1.5 times faster than normal fonts.
Printing results in printing that is approximately 2.0 times longer.

In this embodiment, in order to eliminate the problems mentioned above, the first conveyance roller 1 is disposed before and after the platen row 515.
3 and the 211R feed roller 17 when the magnetic card 1 is printed.
The distance is set to be shorter than the length of the magnetic card 1 in the conveying direction so that the magnetic card 1 is held between the magnetic cards 1 and 7.

Therefore, the magnetic card 1 whose writing has been checked by the magnetic head 27 is held between the second conveyance roller 17 and conveyed between the platen roller 15 and the thermal head 25. Then, the image is printed on the magnetic card 1 while being held between the 21st feeding rows 517. When the magnetic card is conveyed and the rear end of the card 1 leaves the clamped state by the second Ij 41 feed roller 17, the leading edge of the card is moved to the first conveyance date -
513. In other words, during printing, the magnetic card 1 is always held between either the second transport row 517 or the first transport row 513, and therefore, due to the rotation return of the pulse motor 23, the platen roller 15 rotates by the amount of the return rotation. Even if the printing is premature, the printing operation can be performed without being affected by this. Stable printing is possible at all times without any binding or spreading of the print.

Next, reading the magnetic card in the device of this embodiment,
Write processing will be explained.

Platen roller 15. The magnetic barcode 1B of the magnetic card 1 conveyed by the second conveyance roller 17 and the third conveyance roller 19 is read by the magnetic barcode sensor 29. As mentioned above, this magnetic barcode 1B is information that determines the rotation direction of the magnetic head 27 when checking the reading, writing, and writing of data stored or recorded in the recording section of this magnetic card 1. is shown configured with a magnetic barcode 1B.

The magnetic head 27 is a head rotation motor (pulse motor)
31, the magnetic card 1 is rotated about an axis perpendicular to the magnetic card 1 via a belt 32. Further, this magnetic head 27 is a combination head for both reading and writing.

Further, in this embodiment, a potentiometer 33, which specifically detects the rotation angle of the magnetic head 27, is attached to the rotation shaft of the magnetic head 27, as shown in FIG.

FIG. 6 is a plan view schematically showing the potentiometer 33.

A slider 33a is attached to the rotating shaft 27a of the magnetic head 27. Furthermore, the inner portion 1i1i33b centered around this rotating shaft 27a is composed of a resistor. Then, the slider 33a rotates in accordance with the rotation of the magnetic head 27,
A voltage proportional to that position is output.

In this embodiment, the potentiometer 33 for detecting the rotational position of the magnetic head 27 is provided in the magnetic head 27, so that it is possible to detect not only the initial position but also the detected angle of the magnetic head 27 and the target angle. By employing feedback control for matching, etc., fine position control of the magnetic head 27 can be performed. In addition, since the potentiometer 33 is provided within the magnetic head 27, corner 1 position detection can be easily and easily performed without securing a large mounting space.

By the way, if the angle control for the magnetic head 27 becomes impossible due to an accident in the software of the control device, which will be described later, the magnetic head 27 will fly around, and if it rotates in the same direction many times, it will break the control cord line of the magnetic head 27. There is a risk that it will happen.

Therefore, in this embodiment, a stopper 33c is provided in the button mechanism 9 to prevent it from rotating more than 45 degrees left and right from the initial position (position where polishing is performed perpendicular to the longitudinal direction of the card). .
