Description

  The present invention relates to a magnetic information reading apparatus, a magnetic information reading method, and an automatic transaction apparatus.

  Conventionally, as an inexpensive and convenient information recording medium, magnetic stripes are used in various fields of use. For example, in addition to cash cards, credit cards, bankbooks and the like handled by financial institutions, various point cards and ID cards for identifying members and employees are well known.

  Magnetic information readers that read magnetic information written in such magnetic stripes are also widely used. As an example, the operation will be described with reference to an example of a cash card transaction by a magnetic information reader mounted in an automatic transaction apparatus (hereinafter referred to as ATM (Automated Teller Machine)) installed in a financial institution. In ATM, a magnetic head of a magnetic information reading device and a magnetic stripe of a cash card taken into the ATM are brought into close contact with each other, and magnetic information is read by sliding the cash card or the magnetic head in the longitudinal direction of the magnetic stripe.

  However, due to the structure in which the magnetic head and the magnetic stripe are in close contact to read magnetic information, there are many cases in which the magnetic information cannot be read due to factors such as magnetic attenuation, scratches, and dirt on the magnetic stripe portion of the cash card. It has been reported. For this reason, the improvement of the reading rate of the magnetic information written in the magnetic stripe has been a problem.

  Therefore, there is a magnetic card reader / writer in which another data storage track is provided in addition to a predetermined data track of a magnetic card having such a magnetic stripe, and the previous data is always stored in the data storage track ( For example, see Patent Document 1).

  In addition, there is a bankbook handling apparatus that reads a magnetic stripe again after the bankbook is slightly conveyed in the vertical direction when the magnetic stripe of the bankbook cannot be read (see, for example, Patent Document 2).

  On the other hand, in recent years, a multi-track magnetic stripe provided with a plurality of tracks has become widespread. For the purpose of accurately reading the magnetic data of any track of such a multitrack, a magnetic head longer than the length of the magnetic stripe is provided, and the magnetic head is moved in a direction perpendicular to the length of the magnetic stripe. There is also a magnetic information reading device that reads track information at an arbitrary position in the width direction (see, for example, Patent Document 3).

Japanese Patent Laid-Open No. 5-274804 JP 2002-312903 A JP-A-9-282623

  However, in order to provide another data storage track in addition to the predetermined data track of the magnetic card, in addition to the change of the magnetic information reader, the specification of the magnetic stripe must be changed. Therefore, there is a problem that it cannot be applied to the magnetic stripe of the conventional specification that is widely spread. Further, when the position of the magnetic head is fixed and the bankbook is transported in the vertical direction, a space for holding the bankbook in a state shifted in the vertical direction must be secured in addition to the mechanism for transporting the bankbook. Therefore, there is a problem that the enlargement of the apparatus is inevitable.

  In addition, when applying a configuration in which a magnetic head that is long in the longitudinal direction of the magnetic stripe is applied in order to improve the reading rate of magnetic information, there is a problem that the size of the apparatus increases and the cost of the magnetic head increases.

  In one aspect, the present invention can be applied to a conventional magnetic stripe and can improve the reading rate of magnetic information recorded on the magnetic stripe without increasing the size of the apparatus. An object is to provide an information reading apparatus, a magnetic information reading method, and an automatic transaction apparatus.

In order to achieve the above object, a magnetic information reader as shown below is provided. The magnetic information reading apparatus includes a first magnetic head and a second magnetic head, a magnetic head shift unit, and a read control unit. The first magnetic head and the second magnetic head, a track formed in a band shape in the longitudinal direction possess respectively, on the back surface of the first magnetic stripe and card which is formed on the front surface to be read of the card For the second magnetic stripe to be formed, the first magnetic information written in the first magnetic stripe is read, and the second magnetic information written in the second magnetic stripe is read . The magnetic head shift unit is provided for the first magnetic head corresponding to the first magnetic stripe having a lower coercive force than the second magnetic stripe, and the first is in the width direction orthogonal to the longitudinal direction of the track . Shift the reading position of the magnetic head. When reading the first magnetic information of the target track by the first magnetic head arranged at a predetermined position in the reading control unit, if the first magnetic information cannot be read normally, the magnetic head shift unit performs the target track. shifting the reading within the width in the width direction position, carried out in the shifted reading position to read a first magnetic information by the first magnetic head again, and a predetermined number of retries, by shifting the reading position for the object track The number of readings of the first magnetic information performed is compared. If the number of readings does not reach the predetermined number of retries, the reading position is shifted and the first magnetic information is read again. If the number of retries has been reached, the reading of the first magnetic information is terminated and a reading error of the first magnetic information is set. Further, in the first reading, the reading control unit arranges the first magnetic head at the first position in the center in the width direction to read the first magnetic information, and the first magnetic head reads the first magnetic information at the first position . when the magnetic information is not successfully read, in a second position obtained by shifting the first magnetic head at one end in the width direction to read the first magnetic information, the first magnetic in the second position when information is not read correctly, the first magnetic head to read the first magnetic information at a third position shifted to the other end in the width direction, or the first magnetic data can be read correctly, Alternatively, the shift in the width direction is repeated for the read position until the read count of the first magnetic information performed by shifting the read position for the target track reaches a predetermined number of retries.

According to one aspect, when the first magnetic information written in the first magnetic stripe cannot be read, the reading position of the first magnetic head is shifted in the width direction and rereading is performed. Thereby, the reading rate of the 1st magnetic information recorded on the 1st magnetic stripe can be improved. Further, it can be applied to a conventional magnetic stripe and does not increase the size of the apparatus.

Hereinafter, the present embodiment will be described with reference to the drawings.
[First Embodiment]
First, a magnetic information reading apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of the configuration of the magnetic information reading apparatus according to the first embodiment.

  The magnetic information reader 1 shown in FIG. 1 has a card transport unit 11, a magnetic head 12, a magnetic head shift unit 13, and a read control unit 14, and the magnetic information recorded on the magnetic stripe 3 of the card 2. Read information. In FIG. 1, the card 2a is shown as a plan view of the card 2, and the card 2b is shown as a cross-section taken along the line A-A '.

  Here, as shown in the card (plane) 2a, the card 2 has a magnetic stripe 3 to be read formed on the surface along the longitudinal direction. The magnetic stripe 3 is formed with at least one track having a strip shape in the longitudinal direction of the magnetic stripe 3. In this track, magnetic information is recorded in series along the longitudinal direction of the magnetic stripe 3. Therefore, if the position in the longitudinal direction of the track is the same, the same value can be read at any position in the width direction of the track. The width direction of the magnetic stripe 3 and its track is a direction orthogonal to the longitudinal direction of the magnetic stripe 3.

Next, each part of the magnetic information reading apparatus 1 will be described.
The card transport unit 11 transports the card 2 taken into the magnetic information reader 1 in the longitudinal direction of the magnetic stripe 3. The card (cross section) 2b shown in FIG. 1 is an AA ′ cross section of the card (plane) 2a, and the longitudinal direction of the magnetic stripe 3 is the depth direction of FIG. Therefore, the card transport unit 11 transports the card 2 from the front of FIG. 1 in the depth direction or from the back to the front.

  The magnetic head 12 uses the magnetic stripe 3 as a reading target according to the reading control unit 14, closely contacts the reading target track of the magnetic stripe 3, and reads the magnetic information written in this track.

The magnetic head shift unit 13 shifts the position of the magnetic head 12 in the width direction of the magnetic stripe 3 in accordance with the read control unit 14.
The read control unit 14 controls the card transport unit 11, the magnetic head 12, and the magnetic head shift unit 13, reads the magnetic information of the track to be read from the magnetic stripe 3, and outputs it as read data. When the magnetic information cannot be read normally, the magnetic head shift unit 13 is operated to shift the magnetic head 12 in the width direction within the width of the track to be read. As described above, if the position in the longitudinal direction of the track is the same, the same value can be read at any position within the width of the track, so the reading process is performed again at the shifted position. The reading process is performed until reading ends normally or the number of reading retries reaches a predetermined maximum number of retries. If the magnetic information cannot be read normally even when the number of read retries reaches the maximum number of retries, the card 2 is read as an error and the reading process is terminated.

  A reading process of the magnetic information reading apparatus 1 having such a configuration will be described. The magnetic information reader 1 detects that the target card 2 has been inserted into the magnetic information reader 1, and starts the reading process.

  In the reading process by the reading control unit 14, first, the magnetic head shift unit 13 is operated, and the magnetic head 12 is arranged at a predetermined position in the width direction of the reading target track. For example, the position of the central portion in the width direction of the track to be read of the magnetic stripe 3 is used. After positioning the magnetic head 12, the card transport unit 11 is operated to transport the card 2 in the longitudinal direction of the magnetic stripe 3, and the magnetic head 12 is brought into close contact with the magnetic stripe 3 to read the magnetic information of the track to be read. Make it. When the magnetic information of the target track cannot be read normally, the magnetic head shift unit 13 is operated to shift the magnetic head 12 in the width direction within the width of the target track. Then, the card 2 is conveyed again in the longitudinal direction of the magnetic stripe 3 and the magnetic information is read at the position where the magnetic head 12 is shifted. When the magnetic information cannot be read normally again, the magnetic head shift unit 13 is operated to shift the magnetic head 12 in the width direction within the width of the target track. At this time, the magnetic head 12 is shifted to a position different from the previous reading position. Then, reading is performed again at the shifted position. The retry process for reading magnetic information ends when the magnetic information can be read normally or when a predetermined number of retries is reached.

  As described above, in the magnetic information reading apparatus 1 of the first embodiment, when the magnetic information cannot be read from the read target track of the magnetic stripe 3, the magnetic head 12 is shifted within the width of the track and read again. I do. As described above, magnetic information is recorded in series in the track of the magnetic stripe 3 along the longitudinal direction of the track, and the same value is obtained at any position in the width direction as long as the position in the longitudinal direction is the same. Can be read. Therefore, if the magnetic stripe 3 has a part where magnetic attenuation, scratches, dirt, etc. are generated, there are many areas where magnetic information can be read correctly in the width direction of the same track. Thus, by reading the magnetic information by shifting the position of the magnetic head 12 in the width direction, the probability of successful reading of the magnetic information can be increased. Further, it is possible to improve the reading rate without changing specifications such as newly forming a track. Furthermore, since the magnetic head 12 is shifted, it is possible to suppress an increase in the size of the apparatus as compared with the case where the position of the card 2 is shifted.

  In the first embodiment, the magnetic stripe 3 is formed on the card, but the present invention is not limited to this. Any object that can provide the magnetic stripe 3 on the surface may be used. For example, a bankbook may be used. In the first embodiment, the depth direction of the magnetic head 12 is fixed, and the card 2 is conveyed in the depth direction by the card conveying unit 11 to read the information on the magnetic stripe 3, but the position of the card 2 is fixed. However, the magnetic head 12 may be moved in the depth direction.

[Second Embodiment]
Next, as a second embodiment, a case where the magnetic information reader is applied to ATM will be described. FIG. 2 is a schematic diagram showing an ATM according to the second embodiment.

  The ATM 10 includes a touch panel (user operation unit) 20 that constitutes an operation screen operated by a user, a card reading unit 30 that receives an identification card such as a cash card, and a passbook that receives a passbook (general account passbook, time deposit passbook). It has the reading part 40, the banknote depositing / withdrawing part 50 which deposits / withdraws a banknote, and the coin depositing / withdrawing part 60 which deposits / withdraws a coin.

  In the ATM 10, after the user inserts the passbook into the passbook reading unit 40 and inserts the identification card into the card reading unit 30, the user operates the touch panel 20 to perform transaction processing such as cash deposit, cash withdrawal, and transfer. At the same time, it has the function of printing the transaction history on the passbook. It should be noted that a transaction other than the entry of a passbook does not require insertion of a passbook. In the second embodiment, the magnetic information reading device of the present invention is applied to reading the magnetic stripe of the identification card of the card reading unit 30.

FIG. 3 is a block diagram showing the internal structure of the ATM.

Take control.

  The CRW control unit 31 controls the card reading unit 30 and reads information recorded on the magnetic stripe of the identification card according to the control unit 91 and performs writing as necessary. Further, at the end of the transaction, the transaction statement slip may be discharged together with the identification card. The CRW control unit 31 includes a CRW transport control unit 31a, a CRW magnetic R / W (Read / Write) control unit 31b, a CRW image control unit 31c, a CRW ICR / W control unit 31d, and a CRW sensor monitoring. Part 31e. The CRW transport control unit 31a takes in the identification card inserted from the card insertion slot of the card reading unit 30 into the apparatus, and discharges the identification card outside the apparatus at the end of the transaction. Also, when reading the magnetic stripe, control is performed to convey the identification card in the longitudinal direction of the identification card. The CRW magnetic R / W control unit 31b controls reading of magnetic information written on the magnetic stripe of the identification card and writing of magnetic information on the magnetic stripe. The CRW image control unit 31c controls image reading of the identification card. The CRW ICR / W control unit 31d controls reading of information stored in the IC of the identification card and writing of information to the IC. The CRW sensor monitoring unit 31e detects the position of the identification card by the sensor and monitors the position information.

  The passbook control unit 41 controls the passbook reading unit 40 and, according to the control unit 91, transports the inserted passbook into the apparatus and reads information recorded in the magnetic stripe of the passbook. Further, the transaction record is printed on the passbook according to the instruction of the control unit 91.

  The banknote deposit / withdrawal control unit 51 controls the banknote deposit / withdrawal unit 50 and deposits / withdraws banknotes according to the control unit 91. In the withdrawal instruction, a banknote is set in the banknote depositing / withdrawing unit 50, and in the depositing instruction, the banknote inserted by the user into the banknote depositing / withdrawing unit 50 is taken into the apparatus.

  The coin deposit / withdrawal control unit 61 controls the coin deposit / withdrawal unit 60 and deposits / withdraws coins according to the control unit 91. In the withdrawal instruction, coins are set in the coin deposit / withdrawal unit 60, and in the deposit instruction, the coins inserted by the user into the coin deposit / withdrawal unit 60 are taken into the apparatus.

The voice guidance guidance unit 71 provides transaction guidance by voice to the user in accordance with instructions from the control unit 91.
The line connection control unit 81 is connected to a host computer (not shown) via a communication path. Then, transaction information is exchanged with the host computer in accordance with an instruction from the control unit 91.

The transaction process in ATM10 is performed by such control of each part.
Next, the identification card used for ATM10 is demonstrated. The identification card used in the ATM 10 has a magnetic stripe attachment surface, size, attachment position, and the like specified in detail by JIS (Japanese Industrial Standard). In addition, such an identification card is defined as a type 1 conforming to the ISO (International Organization for Standardization) specification and a type 2 conventionally used as a unified specification among banks. Hereinafter, a magnetic stripe conforming to the ISO specification of type 1 is referred to as a magnetic stripe (ISO), and a magnetic stripe of type 2 is referred to as a magnetic stripe (JIS 2). The JIS standard stipulates that a magnetic stripe (JIS 2) is provided on the front surface of the identification card and a magnetic stripe (ISO) is provided on the back surface. Further, an embossed character and an IC chip can be provided on the front surface of the identification card. The embossed characters are read by the CRW image control unit 31c. The IC chip is read and written by the CRW ICR / W control unit 31d.

  Here, two different types of magnetic stripes will be described. A type 1 magnetic stripe (ISO) is a high coercivity magnetic stripe having a plurality of tracks, and has high erasure resistance. For this reason, problems such as magnetic attenuation of the magnetic stripe are unlikely to occur. On the other hand, the type 2 magnetic stripe (JIS 2) is composed of one track, and has a low coercive force and low erasure resistance compared to the magnetic stripe (ISO). For this reason, problems such as magnetic attenuation of the magnetic stripe are likely to occur. However, many type 2 magnetic stripes (JIS2) have already been issued by domestic financial institutions and the like, and in view of such circumstances, it is strongly desired to improve the reading rate of magnetic stripes (JIS2).

  Note that the identification card inserted into the ATM 10 has only a type 2 magnetic stripe (JIS2), only has a type 1 magnetic stripe (ISO), has both magnetic stripes, etc. There is. For this reason, ATM10 is comprised so that it may respond to all types of identification cards.

  Next, a card mechanism unit provided in the card reading unit 30 corresponding to an identification card having two types of magnetic stripes will be described with reference to FIG. FIG. 4 is a schematic diagram illustrating an example of the configuration of the card mechanism unit.

  The card mechanism unit 300 shown in FIG. 4 includes a card transport path 310 through which the identification card 200 is transported, card transport rollers 321 and 322 that transport the identification card 200, and a magnetic stripe ( JIS 2) A first magnetic head section (for JIS 2) 330 that reads 201 and a second magnetic head (for ISO) 340 that reads a magnetic stripe (for ISO) on the back surface. Realizes read and write functions of recorded magnetic information. The surface of the identification card 200 shown in FIG. 4 is the front surface, and a type 2 magnetic stripe (JIS 2) 201 is formed. It is assumed that a type 1 magnetic stripe (ISO) is formed on the back surface (not shown).

  In order to cope with such an identification card 200, the card mechanism unit 300 includes a first magnetic head unit (for JIS 2) 330 corresponding to a type 2 magnetic stripe (JIS 2) 201 and a type 1 magnetic stripe (ISO). And a corresponding second magnetic head (for ISO) 340. In FIG. 4, the first magnetic head unit (for JIS 2) 330 is shown in a state separated from the card transport path 310 for easy understanding, but the first magnetic head unit (for JIS 2) 330 when mounted is a magnetic stripe. (JIS2) It is arranged at a position facing 201. That is, the magnetic head of the first magnetic head unit (for JIS 2) 330 and the second magnetic head (for ISO) 340 face each other with the identification card 200 interposed therebetween.

Each unit of the card mechanism unit 300 will be described.
The card transport path 310 is a transport path for transporting the identification card 200 inserted by the user from the insertion slot of the card reading unit 30. The identification card 200 is conveyed in the card mechanism 300 along the card conveyance path 310 with the longitudinal direction of the identification card 200 as the traveling direction. In the example of FIG. 4, when the identification card 200 is conveyed along the card conveyance path 310, the front surface faces upward, and the magnetic stripe (JIS2) 201 is the first magnetic head unit (for JIS2) 330. Opposite to. At the same time, the magnetic stripe (ISO) on the back surface faces the second magnetic head (for ISO) 340.

  The card transport rollers 321 and 322 transport the card transport path 310 while holding the identification card 200 in accordance with the CRW transport control unit 31a. When the magnetic data of the magnetic stripe is read by the first magnetic head unit (for JIS 2) 330 and the second magnetic head (for ISO) 340, the CRW transport control unit 31a controls the card transport rollers 321 and 322, and The identification card 200 is conveyed at a constant speed in accordance with an instruction from the magnetic R / W control unit 31b. Thereby, the magnetic stripe (JIS 2) 201 and the magnetic stripe (ISO) (not shown) are arranged with the first magnetic head unit (for JIS 2) 330 and the second magnetic head (for ISO) 340 at a constant speed. Pass through the position.

  The first magnetic head unit (for JIS2) 330 is a magnetic field in which the magnetic head of the first magnetic head unit (for JIS2) 330 is written in the magnetic stripe (JIS2) 201 in accordance with the CRW magnetic R / W control unit 31b. Read data. The magnetic stripe (JIS 2) 201 passes through the position where the first magnetic head unit (for JIS 2) 330 is disposed at a constant speed by the card transport rollers 321 and 322 controlled by the CRW transport control unit 31a. The first magnetic head unit (for JIS 2) 330 sequentially reads the magnetic data recorded on the passing magnetic stripe (JIS 2) 201. If the magnetic data cannot be read normally, a retry process is performed in which the position of the magnetic head of the first magnetic head unit (for JIS2) 330 is shifted in the width direction of the magnetic stripe (for JIS2) 201 and read again. . The retry process is performed until the magnetic data can be read normally or the number of retries reaches a predetermined maximum number of retries. Since the magnetic stripe (for JIS2) 201 can read the same value in the width direction, the reading rate can be improved by shifting the magnetic head in the width direction for reading.

The second magnetic head (for ISO) 340 reads the magnetic data written in the magnetic stripe (ISO) by the second magnetic head (for ISO) 340 in accordance with the CRW magnetic R / W control unit 31b. The reading may be performed simultaneously with the reading of the magnetic stripe (JIS 2) 201 by the first magnetic head unit (for JIS 2) 330. The magnetic stripe (ISO) passes through the position where the second magnetic head (for ISO) 340 is disposed at a constant speed by the card transport rollers 321 and 322 controlled by the CRW transport control unit 31a. The second magnetic head (for ISO) 340 sequentially reads the magnetic data recorded in the passing magnetic stripe (ISO). The position of the second magnetic head (for ISO) 340 is fixed, and when reading is not performed normally, the second magnetic head (for ISO) 340 retries reading at the same position. As described above, the magnetic stripe (ISO) is a magnetic stripe having a high coercive force, has high erasure resistance, and hardly attenuates magnetism. In ISO , it is defined to have a plurality of tracks obtained by dividing a magnetic stripe in the width direction, and the width of one track is narrower than that of the magnetic stripe (JIS 2) 201. Therefore, even if the second magnetic head (for ISO) 340 is shifted in the width direction and re-reading is performed, compared with the first magnetic head unit (for JIS 2) 330, the contribution to the improvement of the reading rate is not achieved. Low.

Next, the first magnetic head unit (for JIS 2) 330 will be described with reference to FIG. FIG. 5 is a schematic view showing an example of the configuration of the first magnetic head unit.
The first magnetic head unit (for JIS 2) 330 shown in FIG. 5 includes a first magnetic head (for JIS 2) 331, and a magnetic head shift unit including a screw shaft 332 and a drive pulley 333.

  The first magnetic head (for JIS 2) 331 is held by a carriage that moves in the width direction of the magnetic stripe (JIS 2) 201. Then, the magnetic head shift unit shifts in the width direction of the magnetic stripe (JIS 2) 201, and reads the magnetic data of the magnetic stripe (JIS 2) 201. The shift range is between a position facing the upper end 201a in the width direction of the magnetic stripe (JIS 2) 201 and a position facing the lower end 201b.

  The magnetic head shift unit includes a screw shaft 332 that meshes with the carriage, and a drive pulley 333 that rotationally drives the screw shaft 332. The screw shaft 332 extends in the width direction of the identification card 200 conveyed on the card conveyance path 310, and has a helical groove (screw) that meshes with a carriage that holds the first magnetic head (for JIS2) 331. Have. The drive pulley 333 is provided at one end of the screw shaft 332, rotates in response to a drive signal from a drive circuit (not shown), and rotates the screw shaft 332.

  In the first magnetic head unit (for JIS2) 330 having such a configuration, the drive pulley 333 is driven according to the CRW magnetic R / W control unit 31b, and the screw shaft 332 rotates. As a result, the carriage meshing with the screw shaft 332 moves on the screw shaft 332. In response to this, the first magnetic head (for JIS2) 331 held by the carriage moves on the screw shaft 332 in the same manner as the carriage. As shown in FIG. 5, the head moving direction is the width direction of the magnetic stripe (JIS 2) 201 and is orthogonal to the card conveying direction.

  The CRW magnetic R / W control unit 31b arranges the first magnetic head (for JIS2) 331 at a normal reading position, for example, the central portion in the width direction of the magnetic stripe (JIS2) 201, and the identification card 200 is the identification card 200. The magnetic data is read by conveying in the longitudinal direction. When it is read normally, the read magnetic data is output. If the magnetic head cannot be read normally, the magnetic head shift unit is driven, and the position of the first magnetic head (for JIS2) 331 is shifted, for example, from the central portion in the width direction to one end in the width direction. Read.

  The shift position of the first magnetic head (for JIS2) 331 when the magnetic data cannot be read normally is a position in the width direction where the reading process of the magnetic stripe (JIS2) 201 has not been performed yet. That's fine. However, partial attenuation of magnetism, dust adhesion, and scratches often occur within a certain range. If the distance between the position before the shift and the position after the shift is narrow, the position after the shift is also magnetic. There may be a range such as partial attenuation of. In this case, even if it reads again, it cannot read normally. Therefore, it is desirable to perform re-reading by shifting the position to a certain distance.

  For example, the first magnetic head (for JIS 2) 331 may be alternately shifted from one end side to the other end side around the central portion in the width direction of the magnetic stripe (JIS 2) 201 to retry reading. It is done. As an example, first magnetic head (JIS2) 201 shown in FIG. 5 has one end as upper end 201a and the other end as lower end 201b, and first magnetic head at the center in the width direction of magnetic stripe (JIS2) 201 first. Assume that (for JIS2) 331 is arranged and reading is performed. If reading is not possible at the center, the position of the first magnetic head (for JIS2) 331 is shifted from the center toward the upper end 201a, and reading is performed at the shifted position. If the magnetic data cannot be read normally on the upper end 201a side, the position of the first magnetic head (for JIS2) 331 is shifted from the center to the lower end 201b side, and the magnetic data is read again. The position of the first magnetic head (for JIS2) 331 is shifted until the predetermined maximum number of retries is reached, and magnetic data is read.

Thus, the reading rate can be further improved by shifting the position of the first magnetic head (for JIS2) 331 in the width direction.
A card reading process performed by the CRW control unit 31 by controlling the card mechanism unit 300 having such a configuration will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of a card reading position. In the example of FIG. 6, two retries are performed.

  The CRW control unit 31 sandwiches the identification card 200 taken into the card mechanism unit 300 by the card conveyance rollers 321 and 322 and conveys the identification card 200 along the card conveyance path 310 in the longitudinal direction. At this time, the identification card 200 is conveyed at a constant speed. The magnetic data recorded on the magnetic stripe (JIS 2) 201 on the front surface of the identification card 200 passes through the first magnetic head (for JIS 2) 331 of the first magnetic head unit (for JIS 2) 330 by the identification card 200. When read. At the same time, the magnetic data recorded on the magnetic stripe (ISO) on the back surface of the identification card 200 is read when the identification card 200 passes through the second magnetic head (for ISO) 340.

  At this time, the first magnetic head (for JIS2) 331 is arranged at a position opposite to the first reading position 211 shown in FIG. 6 to read the magnetic data of the magnetic stripe (JIS2) 201. As a result, magnetic data is read in the hatched area corresponding to the first reading position 211. When the reading cannot be performed normally at the first reading position 211, the CRW control unit 31 drives the driving pulley 333 of the magnetic head shift unit, and the position of the first magnetic head (for JIS2) 331 is changed to the magnetic stripe (JIS2). Shift in the width direction of 201. At the second reading position 212 shown in FIG. 6, the first magnetic head (for JIS2) 331 is shifted to the upper end side from the first reading position 211 to perform reading. As a result, magnetic data is read in the hatched area corresponding to the second reading position 212. When the reading cannot be normally performed at the second reading position 212, the CRW control unit 31 drives the drive pulley 333 of the magnetic head shift unit, and the position of the first magnetic head (for JIS2) 331 is changed to the magnetic stripe (JIS2). Shift in the width direction of 201. At the third reading position 213 shown in FIG. 6, the first magnetic head (for JIS 2) 331 is shifted to the lower end side from the first reading position 211 to perform reading.

  In the example shown in FIG. 6, when the magnetic data of the magnetic stripe (JIS2) 201 cannot be normally read in the central portion (first reading position 211) in the width direction, the upper side (second reading position 212) of the central portion. ) Retry is performed by changing the position in the width direction from the lower side of the central portion (third reading position 213). In the example shown in FIG. 6, when the reading cannot be normally performed at the third reading position 213 and the number of retries has not reached the maximum number of retries, the first magnetic head (JIS2) is again placed above the center portion. For) 331 is shifted.

  As described above, even if a part of the magnetic stripe (JIS2) 201 is attenuated by shifting the position of the first magnetic head (for JIS2) 331 and retrying reading, the magnetic stripe (JIS2) ) 201 magnetic data can be read.

  The reading operation will be described with an example. FIG. 7 is a diagram showing a normal identification card and an identification card in which some magnetism is attenuated. In FIG. 7, it is assumed that a region surrounded by a line perpendicular to the longitudinal direction in the magnetic stripes (JIS 2) 221 and 231 represents one magnetic data region. It is assumed that the portion where the line between the adjacent magnetic data areas disappears is the magnetic attenuation unit 232, and the magnetic data cannot be read correctly.

  In the identification card (normal) 220 with no magnetic attenuation shown in (1) of FIG. 7, the magnetic data of the magnetic stripe (JIS2) 221 is normal, and any location in the width direction of the magnetic stripe (JIS2) 221 The magnetic data can be read even if is set as the reading position. Therefore, when reading is performed with the first magnetic head (for JIS2) 331 placed at the first reading position 211, which is the central portion in the width direction, the reading can be completed normally.

  On the other hand, in the identification card (magnetic attenuation) 230 in which a part of the magnetism is attenuated as shown in (2) of FIG. 7, there is a magnetic attenuation part 232 in which a part of the magnetism is attenuated from the central part to the upper part. Therefore, magnetic data cannot be read correctly by reading at the first reading position 211 and reading at the second reading position 212. However, magnetic data can be read correctly in the reading at the third reading position 213.

  As described above, the reading rate can be improved by retrying the reading of the magnetic data by shifting the reading position of the magnetic stripe. In addition, since the magnetic head is shifted, even when magnetic stripes are formed on the front and back surfaces, only the magnetic head that performs retry reading with the reading position shifted is magnetic. What is necessary is just to set it as the structure provided with a head shift part. For this reason, since it is only necessary to provide the magnetic head shift part on one side without increasing the width of the card transport path, it is possible to suppress an increase in size and cost of the apparatus.

  In the above description, the reading position is shifted to the center, up, and down, but the position to shift and the shift order can be arbitrarily set. Also, the number of retries can be set arbitrarily.

  Next, card reading processing by the CRW control unit 31 will be described with reference to FIG. FIG. 8 is a flowchart showing the procedure of the card reading process. Note that the card reading process shown in FIG. 8 shows the reading process of the magnetic stripe (JIS 2) 201. It is assumed that the magnetic stripe (ISO) is read by the second magnetic head (for ISO) 340 whose position is fixed as in the conventional case.

  Upon detecting that the identification card 200 has been inserted into the ATM 10, the CRW control unit 31 starts a card reading process. The following reading process is performed by the CRW transport control unit 31a and the CRW magnetic R / W control unit 31b in accordance with the CRW control unit 31.

  [Step S01] The first magnetic data reading is performed. The first magnetic data reading is performed in a state where the first magnetic head (for JIS2) 331 is disposed at the normal position. Here, the normal position is the center in the width direction of the region where the magnetic stripe (JIS 2) 201 is formed. With the first magnetic head (for JIS2) 331 positioned at the center of the magnetic stripe (JIS2) 201 in the width direction, the identification card 200 is conveyed in the longitudinal direction of the magnetic stripe (JIS2) 201 by the card conveying rollers 321 and 322. The The first magnetic head (for JIS 2) 331 is in close contact with the magnetic stripe (JIS 2) 201 and sequentially reads the magnetic data recorded on the passing magnetic stripe (JIS 2) 201.

  [Step S02] It is determined whether or not reading of magnetic data by the first magnetic head (for JIS2) 331 is normal. When the reading of magnetic data is normally completed, the process proceeds to step S03. When the reading of magnetic data is not normally completed, the process proceeds to step S04.

[Step S03] When the reading of the magnetic data is normally completed, the card reading is regarded as normal and the process is terminated.
[Step S04] When the reading of the magnetic data is not normally completed, the reading position by the first magnetic head (for JIS2) 331 is changed. The magnetic head shift unit is operated to move the first magnetic head (for JIS 2) 331 to a position where reading has not been performed in the reading process so far.

  [Step S05] With the first magnetic head (for JIS2) 331 disposed at the position determined in step S04, the identification card 200 is conveyed in the longitudinal direction of the magnetic stripe (JIS2) 201 by the card conveying rollers 321 and 322. The The first magnetic head (for JIS 2) 331 is in close contact with the magnetic stripe (JIS 2) 201 and sequentially reads the magnetic data recorded on the passing magnetic stripe (JIS 2) 201.

  [Step S06] The first magnetic head (for JIS 2) 331 determines whether or not the reading of magnetic data is normal. If the magnetic data can be read normally, the process proceeds to step S03. If the magnetic data cannot be read normally, the process proceeds to step S07.

  [Step S07] The number of NGs in which the magnetic data could not be read normally is increased by 1, and compared with a predetermined upper limit n of the number of retries, it is determined whether the number of NGs is less than n. If it is less than n times, the process proceeds to step S04, and if it has reached n times, the process proceeds to step S08.

[Step S08] Since the number of failed magnetic data readings has reached a specified value (n times), the process ends as a card reading error.
By executing such a procedure, when the magnetic data of the magnetic stripe cannot be read normally at a predetermined normal position, the magnetic head is shifted in the width direction of the magnetic stripe and a retry is performed. As a result, even when magnetic attenuation, scratches, dirt, etc. occur in a part of the magnetic stripe, the probability of successful reading of magnetic data can be increased. As a result, it is possible to increase the reading rate of the magnetic data recorded on the magnetic stripe and improve the convenience for the user.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the printing apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic storage device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic storage device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Examples of the optical disc include a DVD (Digital Versatile Disc), a DVD-RAM (Random Access Memory), a CD-ROM (Compact Disc Read Only Memory), and a CD-R (Recordable) / RW (ReWritable). Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, portable recording media such as a DVD and a CD-ROM in which the program is recorded are sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. In addition, each time a program is transferred from a server computer connected via a network, the computer can sequentially execute processing according to the received program.

  In addition, at least a part of the above processing functions can be realized by an electronic circuit such as a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or a PLD (Programmable Logic Device).
