Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium processing device such as a card processing device for reading and writing magnetic information on a magnetic prepaid card used as a bus coupon, for example.

[0002]

2. Description of the Related Art Recording systems for recording media include, for example, a magnetic recording system, a print recording system, a punch hole recording system, and the like, and these recording systems have been put to practical use in all information-oriented equipment. The magnetic recording method can easily change the recorded contents and can record a large amount of information. Also,
The print recording method has the convenience that the recorded information can be visually recognized without using the apparatus. Due to these advantages, there is great expectation for construction of a card system having a card as a recording medium and having magnetic information and print information.

The recorded information on the card can read / write magnetic information, print printed information, or, depending on use,
Perform work such as punching holes as appropriate. For the reading / writing of magnetic information, the printing of print information, or the punching of holes, it is required that the processing position of the card, which is a recording medium, be highly accurate.

Furthermore, when performing magnetic processing and printing processing, it is necessary to manage the head gap between the rubber roller as the platen roller and the magnetic head or the printing head. Further, since the magnetic processing reads and writes magnetic information, it is necessary to guarantee the normal operation of the magnetic head before starting the magnetic processing.

[0005]

By the way, in any of the magnetic recording method, the print recording method, and the punch hole recording method, the processing is performed on the initial adjusted setting position. In order to perform such processing at the set position, the card was conveyed from one end by a predetermined distance and processed, but as the number of times of processing increased, or at the time of initial adjustment and the environment (temperature, humidity, etc.) However, there is a problem in that the processing is not performed for a predetermined set position when the values are different.

For example, when the temperature at the time of use is lower than the temperature at the time of initial setting with respect to the temperature, a component used for carrying a card, for example, a carrying roller made of rubber contracts and the diameter of the carrying roller becomes small, The transport distance becomes shorter than that at the time of initial setting, and as a result, the processing is not performed at a predetermined setting position.

Further, when performing the processing of the magnetic recording method or the print recording method, it is necessary to ensure the gap between the magnetic head or the print head and the platen roller at a predetermined set position. However, since the platen roller is made of rubber, its dimensions are affected by the environment (temperature, humidity, etc.). For example, when the temperature during use is lower than the initial setting, the platen roller contracts, Since the diameter of the platen roller becomes smaller, it becomes wider than the gap at the time of initial setting. For this reason, magnetic recording and print recording cannot be performed. Therefore, it is necessary to adjust the gap with extremely high accuracy in order to reduce the influence on the change in the environment.

Further, in the case of performing the magnetic recording method, when the magnetic information is read abnormally or the magnetic information is written abnormally,
It is necessary to check a number of items such as whether the cause is the magnetic head, the card itself, or the transport system. In addition, when the magnetic head is abnormal, there is a problem that the magnetic information normally recorded on the card is destroyed when not processed. Usually, the first cause of magnetic head abnormality is coil breakage, and other failures of the head itself are small.

Therefore, according to the present invention, when the magnetic processing, the printing processing, and the punching processing are performed on the recording medium, the processing position is automatically corrected, and the processing can always be performed at a predetermined position with high accuracy. An object is to provide a recording medium processing device.

Further, according to the present invention, when the magnetic processing and the printing processing are performed on the recording medium, the head gap thereof can be guaranteed regardless of the difference between the environment at the time of initial adjustment setting and the environment at the time of actual operation. An object of the present invention is to provide a recording medium processing device that can be used.

Further, according to the present invention, when magnetic processing is performed on a recording medium, in the case of a readable / writable magnetic head, an abnormality of the magnetic head is detected before the processing,
An object of the present invention is to provide a recording medium processing device capable of preventing abnormal processing.

First, in performing the magnetic processing, the printing processing, and the punching hole processing, the processing position is automatically corrected to perform processing at a predetermined position, which will be described in detail below.

That is, in carrying out the magnetic processing, the punching processing and the printing processing, first, when the magnetic processing is carried out, the magnetic card C is conveyed by the conveying path 22 in the direction of arrow b in the figure. When the conveyed magnetic card C passes through the detector 30, the detector 30 reads the positions of the punch holes already formed in the magnetic card C.

Next, when the detector 29 detects the conveyed magnetic card C, the magnetic information on the conveyed magnetic card C is read by the magnetic head 27. At this time, the CPU 41 determines whether or not the read magnetic information has an abnormality, and the processing in the case of the abnormality is as described above.

When the magnetic information read from the magnetic card C is normal, the magnetic card C is further conveyed in the direction of the arrow b in the figure until it passes the detector 31. afterwards,
When the detector 31 detects the passage of the magnetic card C, the conveyance path 22 is reversed to convey the magnetic card C in the direction of the arrow a, while the magnetic head 27 causes the magnetic card C to have a predetermined start reference. The magnetic information writing process is performed at the position X.

When the writing process is completed, the magnetic card C is further conveyed in the direction of arrow a in the figure to confirm the content of the magnetic information to be written, and is conveyed until it passes the detector 29. After that, when the detector 29 detects the passage of the magnetic card C, the conveyance path 22 is reversed to convey the magnetic card C in the direction of the arrow b in the drawing, while the magnetic head 27 writes the magnetic card C. Magnetic information can be read.

At this time, the CPU 41 detects the writing position of the actual magnetic information based on the read magnetic information in addition to the presence or absence of abnormality in the read magnetic information, and also checks the writing position. That is, the CPU 41 determines whether or not there is an abnormality in the read magnetic information, and if there is an abnormality, the conveyance path 22 is reversed to convey the magnetic card C in the direction of the arrow a in the drawing, and the card insertion slot 11 Discharge from.

When the read magnetic information is normal, the CPU 4
1 compares a predetermined start reference position X with the detected actual writing position, and if there is a difference between the two, stores the difference as ΔX and stores it in the RAM 43.

After that, by reversing the conveying path 22, the magnetic card C is conveyed in the direction of arrow a in the figure, and the detector 3
Transport until 1 is passed. After that, when the detector 31 detects the passage of the magnetic card C, the conveyance path 22 is reversed to convey the magnetic card C in the direction of the arrow b in the drawing.
When the detector 31 detects the magnetic card C, the magnetic card C is further conveyed to a predetermined position Y, and the punch unit 32 punches a punch hole such as a reference hole for the card balance.

Thereafter, the magnetic card C is further attached to the arrow b in the figure.
The CPU 41 checks whether or not the punched hole is opened at a predetermined position Y without any abnormality by reading the punched hole after being punched by the detector 36 while being conveyed in the direction.

If the result of this check is that the punched hole is abnormal, for example, if the punched hole has not been punched, the conveyance path 22 is reversed and the magnetic card C is moved until it passes the detector 31 by the arrow shown in the figure. Transport in the a direction. After that, when the detector 31 detects the passage of the magnetic card C, the conveyance path 22 is reversed to convey the magnetic card C in the direction of the arrow b in the figure. Magnetic card C to position Y
Then, the punch section 32 punches a punch hole such as a reference hole for the card balance in the magnetic card C.

Thereafter, the magnetic card C is further attached to the arrow b in the figure.
The CPU 41 reads again the punched hole after punching by the detector 36 while conveying in the direction, and the CPU 41 checks again whether or not the punched hole that has just been opened is abnormally opened at a predetermined position Y.

Here, if there is an abnormality again, an error code or the like is displayed on the card processing device operation panel 15 used by the clerk to manually operate the card processing to inform the clerk of the abnormality. Since the magnetic processing of the magnetic card C at this point has been completed, there is no problem in the card processing, and therefore the printing processing is continued.

On the other hand, if the read punch hole is normal, C
The PU 41 detects the read punch hole position (actual punch hole forming position), compares the detected actual punch hole forming position with a predetermined start reference position Y, and determines the difference between the two. If there is, the difference is ΔY and R
Store in AM43.

Next, by reversing the conveying path 22, the magnetic card C is conveyed in the direction of arrow a in the figure until it passes the detector 37. After that, the detector 37 turns the magnetic card C
When the passage of the magnetic card C is detected, the conveyance path 22 is reversed to convey the magnetic card C in the direction of the arrow b in the drawing, and the detector 3
When the timing at which the print head 33 passes through 7 and the predetermined position Z for printing based on the magnetic information processed earlier approach the print head 33 and the platen roller 35, the solenoid 3
By driving the print head 33, the print head 33 is pressed against the platen roller 35 with the magnetic card C sandwiched therebetween, and the boarding fee and the card balance are printed on the magnetic card C.

The magnetic card C that has completed the printing process is further conveyed in the direction of the arrow b in the figure, and is read and scanned by the image reading sensor 38, so that the CPU 41 causes the print head 33 to pass through the print position detection circuit 46. Check if the printed information is printed in the specified position. Then, the CPU 41 detects the actual print position by the print head 33 via the print position detection circuit 46, compares the detected actual print position with a predetermined reference position Z determined in advance, and establishes a distance between the two. If there is a difference, the difference is ΔZ
And stored in the RAM 43.

The magnetic card C is further conveyed in the direction of the arrow b in the figure, passes through the detector 39, and is discharged to the card take-out port 14 as the magnetic card C for which payment has been completed. In this way, when processing is performed on one magnetic card C, the difference (deviation amount) ΔX with respect to each of the magnetic processing reference position X, the punch hole processing reference position Y, and the print processing reference position Z. , ΔY, ΔZ are calculated and stored, so that for the magnetic card C to be processed next, the reference position X ′ for magnetic processing, the reference position X ′ for punching processing, the reference position Y ′ for punching processing, and the reference position for printing processing are corrected. Each process is performed by Z ', and the correction is automatically performed.

However, these processing reference positions are actually controlled by the times Tx, Ty, Tz,
It is corrected by taking into consideration the speed difference caused by the difference between the reading direction and the processing direction. Specifically, the reading of the magnetic information is performed in the direction of the arrow b in the figure with the conveying speed Vb.
Since the writing of magnetic information is performed in the direction of arrow a at the conveyance speed Va, a speed difference ΔV (difference between Va and Vb) occurs.

That is, the reference position X at the time of reading is calculated by T
It is represented by the product of x and Vb, and in order to locate the reference position at the time of writing, processing is performed at time Tx ′ calculated from the quotient of X and Vb. Similarly for Ty and Tz, T
It is processed by y ', Tz'.

Next, when performing magnetic processing and printing processing, the head gap is guaranteed regardless of the difference between the environment (temperature and humidity) at the time of initial adjustment setting and the environment (temperature and humidity) at the time of actual operation. Will be described in detail below.

FIG. 4 shows a magnetic processing section provided in the card processing apparatus main body 21. The magnetic processing unit includes a magnetic head 27 fixed to a base (not shown), a platen roller 28 at one end, and an adjusting roller 61 as an adjusting member configured by a rubber roller having the same shape and material as the platen roller 28 at the other end. Respectively rotatably held, and the platen roller 2 is attached to the tip on the platen roller 28 side.
8 is used to adjust the gap between the platen roller 28 and a holder 64 which holds a pressing coil spring 62 as a spring member for applying a pressing force to the 8, and which rotates about a fulcrum 63 at the center. It is composed of a gap adjusting plate (fixing member) 65 that can be moved and adjusted in the directions of arrows c and d (vertical direction) in the drawing.

Further, the platen roller 28 is the magnetic head 2
The required gap position for 7 is provided at a position where an adjustment roller 61 made of a rubber roller having the same shape and material as the platen roller 28 is in contact with the gap adjustment plate 65 on the opposite side with respect to the fulcrum 63. . That is, for example, when the platen roller 28 thermally contracts due to the ambient temperature, the adjusting roller 61 having the same shape and the same material as the platen roller 28 also thermally contracts, so that the position of the platen roller 28 with respect to the magnetic head 27 is It does not change.

When the gap is adjusted and the gap width is desired to be wide, the gap adjusting plate 65 is moved in the direction of arrow d in the drawing by a moving screw or the like not shown. By this adjustment, the adjusting roller 61 having the same shape and the same material as the platen roller 28 is pushed in the direction of the arrow d in the drawing, and the holder 64 rotates about the fulcrum 63. This movement of the holder 64 moves the platen roller 28 held at the other end in the direction of arrow c in the figure.

When it is desired to make the gap width narrow,
The gap adjusting plate 65 is moved in the direction of arrow c in the drawing by a moving screw or the like not shown. By this adjustment, the adjusting roller 6 having the same shape and the same material as the platen roller 28 is formed.
1 is pushed in the direction of the arrow c in the figure, and the holder 64 rotates about the fulcrum 63. The movement of the holder 64 moves the platen roller 28 held at the other end in the direction of the arrow d in the figure.

By carrying out such an adjustment, when the magnetic card C is conveyed through the conveying path 22, the pressing spring 62 can always ensure a constant necessary pressing force. Further, even when a foreign substance other than the magnetic card C for normal processing is inserted, the platen roller 28 can escape in the direction of the arrow c in the figure.

Although not described, the print head 33
The print processing unit can also have the same configuration as the magnetic processing unit. Next, in performing a magnetic process, in the case of a readable / writable magnetic head, an abnormality of the magnetic head is detected before performing the process, and the point of preventing the abnormal process will be described in detail below.

FIG. 5 shows the magnetic head 27 and reading / reading.
The portion of the write circuit 44 is shown. The magnetic head 27
A core 71 having a predetermined gap in order to generate a leakage magnetic flux for performing magnetic processing on the magnetic recording layer of the magnetic card C.
And a write coil 72 wound around the core 71.
And a reading coil 73. A read / write circuit 44 is connected to the write coil 72 and the read coil 73. That is, the write coil 72 is connected to a write circuit 74 that outputs a pulse voltage for writing, and the read coil 73 is connected to a read circuit 75 that reads a pulse voltage according to the read magnetic information. . The writing circuit 74 and the reading circuit 75 are connected to the CPU 41, and the writing timing and the like are controlled by the CPU 41.

In such a configuration, for example, when the power of this apparatus is turned on, the CPU 41 causes the writing circuit 74 to operate.
With respect to the predetermined pulse voltage P1
An instruction is issued to output (see FIG. 6A). Receiving this, the writing circuit 74 outputs a specific pulse voltage P1 as shown in FIG. The output specific pulse voltage P1 is applied to the write coil 72, whereby an induced current I corresponding to the specific pulse voltage P1 is generated in the core 71, and the induced current I causes the read coil 73 to pulse. A pulse voltage P2 having the same shape as the voltage P1 (see FIG. 6B).
Is generated and read by the reading circuit 75.

The CPU 41 compares the pulse voltage P1 output from the writing circuit 74 with the pulse voltage P2 input to the reading circuit 75. As a result of this comparison, as shown in FIG. 6, the pulse interval Δt of the pulse voltage P1 and the pulse voltage P2
If the pulse intervals Δt ′ of 1 are equal, the CPU 41 determines that both the write coil 72 and the read coil 73 are normal, and sets the present apparatus to the operable state.

As a result of the above comparison, when the pulse interval Δt of the pulse voltage P1 and the pulse interval Δt 'of the pulse voltage P2 are not equal, the CPU 41 determines that the write coil 72 or the read coil 73 has an abnormality, and performs the card processing. By displaying an abnormality on the operation panel 15 for the apparatus, the staff is informed of that fact.

As described above, according to the above embodiment,
Each time a magnetic card is processed, the difference between the predetermined position of the magnetic processing, the predetermined position of the printing processing, the predetermined position of the punching hole processing and the position where the actual magnetic processing, printing processing and punching processing is performed is detected, and the difference Based on the above, the magnetic processing and the printing are performed on the magnetic card by performing the processing at the predetermined position of the magnetic processing of the magnetic card to be processed next, the predetermined position of the printing processing, and the position corrected for the predetermined position of the punch hole processing. When performing the processing and punch hole processing, the processing position can be automatically corrected so that the processing can always be performed at a predetermined position with high accuracy. Therefore, it is possible to eliminate the trouble of the position adjustment work of each process at the time of manufacturing this device and the readjustment work at the time of regular inspection during operation, and it is possible to improve the reliability of this device.

Further, according to the above-described embodiment, when the platen roller of the magnetic recording portion changes its outer shape due to thermal contraction or expansion due to changes in environmental temperature and humidity, the platen roller is moved to the opposite side with the predetermined point as the fulcrum. An adjustment roller is provided, whose external shape changes like thermal expansion and contraction due to changes in environmental temperature and humidity, similar to the platen roller, and ensures a constant head gap by utilizing the external shape change of the adjustment roller. Therefore, even if there is a difference between the operating environment temperature and humidity of this device and the environment temperature and humidity when this device is manufactured, the head gap is reduced regardless of the amount of change in the outer shape of the platen roller due to thermal contraction or expansion. Since it is kept constant, a large adjustment margin can be secured at the time of manufacturing, and the reliability of this device can be improved while facilitating the adjustment work.

Further, according to the above embodiment, for example, when the power is turned on, a specific pulse signal input from the write coil of the readable / writable magnetic head and a pulse signal obtained from the read coil by the induced current by the pulse signal. When the two pulse signals do not match with each other and it is determined that the magnetic head is abnormal, it is possible to detect the abnormality of the magnetic head before performing the process and prevent the abnormal process. Therefore, if there is an abnormality in the magnetic head, it is possible to detect the abnormality before processing the magnetic card, determine the cause of the magnetic processing abnormality, and avoid the risk of destroying the normal magnetic information. The reliability of this device can be improved.
