Description

  The present invention relates to a magnetic stripe data processing apparatus for editing a signal read from a magnetic stripe such as a bankbook.

  Today, deposits and withdrawals of deposits, account transfers, and the like are widely performed using automatic machines (for example, ATM (Automated Teller Machine)) installed in banks and convenience stores. In addition, when using ATM, a medium such as a cash card or a bankbook (hereinafter simply referred to as a bankbook) is used to deposit and withdraw cash.

  For example, when using a bankbook, information (magnetic data) such as a customer name, a bank name, and an account number stored in the magnetic stripe of the bankbook is read by the magnetic head, and the above-described various processes are performed.

  And, it is necessary to ensure compatibility between the read / write devices of the magnetic stripe mounted on the ATM so that the transaction of the bankbook can be performed at any ATM. In order to ensure compatibility, for example, a passbook handling apparatus has been proposed that can confirm the positional deviation of the reading head with respect to the recording head (Patent Document 1).

In the NRZI system, a signal is written on the track 0 side corresponding to data “0” of a data string (for example, 0, 1, 0, 0, 1, 0), and the track 1 side corresponding to data “1”. A signal is written to each track, and a magnetization transition line (long vertical line) is recorded on each track.

  Returning to FIG. The bankbook 100 is inserted from the bankbook insertion part 5a described above, drawn into the machine, and conveyed into the MS unit 20 by the conveyance roller pairs 18a to 18c. 7 is a view seen from the opposite direction to FIG. 4. In FIG. 7, the passbook insertion part 5a is located on the right side, and the passbook 100 is conveyed in the left direction (p direction). The bankbook 100 is stopped by the printer control unit 10 at a position where the front end of the bankbook 100 contacts the stopper 110 in the MS unit 20.

  The magnetic head 32 is attached to a travel guide (not shown), and travels in both forward (right → left) and return (left → right) directions with respect to the magnetic stripe 102 by the motor 33. When traveling on the forward path, the magnetic head 32 moves in the order of h1 → h2 → h3 → h4. The magnetic head 32 is retracted to a position lowered by one step so as not to contact the magnetic stripe 102 at h1 and h4 by the traveling guide.

  The contact start point h <b> 2 and the contact end point h <b> 3 are set at positions outside the both ends of the magnetic stripe 102, and the magnetic head 32 can perform reading over the entire length of the magnetic stripe 102. Note that writing is performed only in the forward path, and reading is performed in both the forward path and the backward path.

  The MS control unit 31 controls the reading start position of the magnetic head 32 by an SPS signal, and controls the reading end position of the magnetic head 32 by an EPS signal (the reverse is true in the case of a return path).

  In the magnetic stripe 102, six blocks of a front dummy D1, a start code D2, transaction data D3, an end code D4, a check code D5, and a rear dummy D6 are written in order from the right. In transaction data D3, data indicating an account number, a passbook type, a branch number, and the like related to the pasted passbook 100 is described. The start code D2 and the end code D4 are codes indicating the start and end of transaction data. The check code D5 is data for confirming whether the reading is normally performed in comparison with the read data.

  The position of the track written in the magnetic stripe 102 in the front-rear direction (the left-right direction in the figure) is determined by specifications in order to ensure compatibility between ATMs. Further, the distance S1 from the position of the SPS to the start code D2 is also a constant value depending on the specification.

  FIG. 9 is a diagram showing the data written in the magnetic stripe 102 by the FM method and the running mode of the magnetic head 32. The FM method is an abbreviation of Frequency Modulation, which is 1 when there is a bit at the center of the bit between appropriate periods in one track, and 0 when there is not.

  FIG. 10 is a diagram illustrating an example of the magnetization transition line by the FM method. In the FM method, a magnetization transition line (vertical thick line) as shown in the figure is recorded on a track corresponding to a data string (for example, 0, 1, 0).

  Returning to FIG. As in the case of FIG. 7, the bankbook 100 is positioned against the stopper 110. 9 is also a view seen from the opposite direction to FIG. 4, as in FIG. 7, and the bankbook 100 is conveyed in the left direction (p direction).

  The magnetic head 32 is attached to a travel guide (not shown), and travels in both the forward path (left → right) and the return path (right → left) with respect to the magnetic stripe 102 by the motor 33. When traveling on the forward path, the magnetic head 32 moves in the order of h11 → h12 → h13 → h14. The magnetic head 32 is retracted to a position lowered by one step so as not to contact the magnetic stripe 102 at h11 and h14 by the traveling guide.

  The contact start point h12 and the contact end point h13 are set at positions outside the both ends of the magnetic stripe 102, and the magnetic head 32 can execute reading over the entire length of the magnetic stripe 102. Note that writing is performed only in the forward path, and reading is performed in both the forward path and the backward path.

  The MS control unit 31 controls the reading start position of the magnetic head 32 by an SPS signal, and controls the reading end position of the magnetic head 32 by an EPS signal (the reverse is true in the case of a return path).

  In the magnetic stripe 102, eight blocks of a dummy D11, a front dummy D12, a start code D13, transaction data D14, an end code D15, a check code D16, a back dummy D17, and a dummy D18 are written in order from the left. The distance S2 from the SPS position to the start code D13 is also a constant value depending on the specification.

  FIG. 11 is a diagram showing a comparison between the case where the track writing position is normal (according to the specification) and the case where it deviates from the specification in the NRZI system of FIG. FIG. 11A shows a case where two tracks 104 a and 104 b are written at the specified position on the magnetic stripe 102.

  FIG. 11B shows a case where the write start position is shifted to the left side, and the end positions (left end) of the two tracks 104 a and 104 b are just below the left end of the magnetic stripe 102. For example, this is the case when the bankbook 100 is written in a state where it stops at a position before the stopper 110 shown in FIG. Alternatively, such a state can also occur when writing is performed at ATM 1 in which the adjustment of the write start position of the magnetic head 32 with respect to the magnetic stripe 102 is shifted.

  FIG. 11C shows a case where the write start position is shifted to the right side, and the start positions (right ends) of the two tracks 104 a and 104 b are just below the right end of the magnetic stripe 102. For example, when the leading end of the bankbook 100 is turned over by the stopper 110 shown in FIG. 7 and is written while being conveyed at a deeper position, this is the case. Alternatively, such a state can also occur when writing is performed at ATM 1 in which the adjustment of the write start position of the magnetic head 32 with respect to the magnetic stripe 102 is shifted.

  FIG. 12 is a diagram showing a comparison between the case where the track writing position is normal (according to the specification) and the case where it deviates from the specification in the FM method of FIG. FIG. 12A is a diagram in which a track 104 is written at a specified position with respect to the magnetic stripe 102.

  FIG. 12B shows a case where the write start position is shifted to the left side, and the start position (left end) of the track 104 is just below the left end of the magnetic stripe 102. FIG. 12C shows a case where the write start position is shifted to the right and the end position (right end) of the track 104 is just below the right end of the magnetic stripe 102. The cause of the deviation is the same as in the NRZI system.

  As described with reference to FIGS. 7 and 9, the magnetic head 32 reads the magnetic signal by running the entire length of the magnetic stripe 102, so even if the track 104 is not at the normal position of the magnetic stripe 102, any position can be obtained. If it is written in, it is acquired as a magnetic signal, binarized, and stored as MS data.

On the other hand, the MS data editing unit 35 performs data editing work based on the MS data when it can detect predetermined data (hereinafter referred to as a start code D2) in the MS data within a certain time range after the start of traveling of the magnetic head 32. Start. This is because if the process of searching for the start code D2 from the entire MS data is performed, the search process takes too much time, and the passbook reading process is delayed.
The fixed time for detecting the start code D2 is determined based on the (normal) written position (FIG. 11A or FIG. 12A) according to the specification.

  Therefore, when the write start position is greatly shifted as shown in FIGS. 11B, 11C, 12B, and 12C, the MS data within a certain time range after the start of traveling of the magnetic head 32 is The start code D2 cannot be detected, and the passbook 100 is processed as a read error even if predetermined data is recorded.

  Therefore, in the present embodiment, the MS data editing unit 35 additionally changes the specified time range and performs editing so that data editing can be performed even on the magnetic stripe 102 whose write start position is greatly shifted. Execute the editing process.

  13A and 13B are flowcharts 1 and 2 for explaining the procedure of the editing process by the MS data editing unit 35. In the following flowchart, in addition to the above-described additional editing process, in the case where the read jitter is large, the NRZI method is taken as an example in order to explain the permutation editing process in which the magnetization transition lines of tracks 0 and 1 are sequentially read. However, the additional editing process is also applied to FM systems other than the NRZI system or other systems.

  The MS control unit 31 performs forward path side reading (step S10). The magnetic head 32 is run from h1 to h4 with respect to the passbook 100 conveyed to a predetermined position in the MS unit 20 (FIG. 7), and the magnetic signal written in the magnetic stripe 102 is read by the magnetic head 32. The read magnetic signal is binarized and stored in the memory 37 as MS data. The magnetization transition line corresponds to the H data of the binarized data (H, L). Further, the MS data is managed by the time based on the passage of the magnetic head 32 through the SPS.

  The MS data editing unit 35 detects the previous dummy D1, which is a predetermined data string, at the head of the MS data from the MS data stored in the memory 37, and determines whether the previous dummy D1 has been detected (step S12). .

  When the MS control unit 31 determines that the previous dummy D1 cannot be detected by the MS data editing unit 35 (No in step S12), the forward reading side reading execution in step S10 is determined to be an error, and reading from the reverse direction (return reading) is performed. To do so, go to step S50 in FIG. 13B.

  When the MS data editing unit 35 determines that the previous dummy D1 has been detected (Yes in step S12), the MS data editing unit 35 determines whether the start code D2 has been detected within the specified time range (step S14). The specified time is the time from when the magnetic head 32 passes through the SPS until the start code D2 recorded at the position determined by the specification is read.

  As shown in FIG. 7, when the distance from the SPS to the start code D2 is S1 (mm) and the speed of the magnetic head 32 by the motor 33 is V (mm / sec), the time until reading is t0 = S1 / V. . In consideration of the variation, the specified time range is set to t0 ± 10%. The specified time range (t0 ± 10%) is set by the specified time setting unit 36.

  When the MS data editing unit 35 determines that the start code D2 is detected within the specified time range (t0 ± 10%) (Yes in step S14), the MS data editing unit 35 determines whether the jitter of the MS data is normal ( Step S16).

  The read magnetic transition line should ideally be at a constant time interval as shown in FIG. 8, but the speed of the magnetic head 32 at the time of writing and reading fluctuates. Unevenness occurs.

  The jitter on the standard is set to ± 20%, for example, and if it is within ± 50% when the margin is viewed, it is determined that editing is possible, that is, normal.

  When the MS data editing unit 35 determines that the jitter of the MS data is normal (step S16 Yes), the MS data editing unit 35 performs a normal editing process (also referred to as normal editing) (step S18). The MS data editing unit 35 determines whether all the edited bits are normal (step S20). If all the bits are normal (step S20 Yes), the MS data editing unit 35 ends the reading and sends the edited transaction data to the printer control unit 10. Output.

  If the MS data editing unit 35 determines that all bits are not normal (No in step S20), the process proceeds to step S50.

  Returning to Step S16, when the MS data editing unit 35 determines that the jitter is not normal (No in Step S16), it determines whether the jitter is 200% or more (Step S22). When the MS data editing unit 35 determines that the jitter is not 200% or more (No in step S22), the MS data editing unit 35 performs a permutation editing process (step S24).

  The permutation editing process is an editing method in which the magnetization transition lines read from the track (track 0) 104a and the track (track 1) 104b are assigned to 0 or 1 bits in the read order. As described above, the process is limited to the NRZI system.

  FIG. 15 is a diagram for specifically explaining the permutation editing process. FIGS. 15A to 15C are diagrams showing magnetization transition lines read in the track (track 0) 104a and the track (track 1) 104b written in correspondence with data bits in units of 4 bits. is there. The direction of time is the right direction. As described above, 0 bits are written to track 0 and 1 bit is written to track 1. Each number of the magnetization transition line is a number corresponding to a data bit.

  FIG. 15A is a diagram showing magnetization transition lines read from the track 104a and the track 104b when there is no occurrence of jitter. All the magnetization transition lines are read at equal intervals, and the interval between the magnetization transition lines is indicated here as 100%.

  FIG. 15B shows a case where the 6-bit magnetization transition line is read at a timing when it approaches the 5-bit magnetization transition line by −75% from the original position. For example, when the magnetic head 32 travels extremely slowly when writing between the 5th and 6th bits, or conversely, when the reading between the 5th and 6th bits is performed, the magnetic head 32 travels. This is the case when it becomes extremely fast. Moreover, these may be combined.

  FIG. 15C shows a case where the 6-bit magnetization transition line is read at a timing separated from the 5-bit magnetization transition line by + 75% (175%) from the original position. For example, this is a case where the magnetic head 32 travels extremely fast during reading between the 5th and 6th bits or extremely slow during reading.

  In the case of normal editing processing, data editing is not performed if the jitter of the MS data is ± 50% (50% to 150%) or more. Therefore, the 6th bit data as shown in FIGS. Is overlooked and results in an error. In the permutation editing process, data is edited in accordance with the order of the magnetization transition lines, regardless of the interval between the magnetization transition lines. Therefore, the sixth bit in which large jitter as shown in FIGS. 15B and 15C has occurred. Even so, it can be read without being overlooked.

  After the permutation editing process, the MS data editing unit 35 determines whether all the read bits are normal (step S20). Step S20 has already been described and will be omitted.

  Returning to step S22, if the MS data editing unit 35 determines that the jitter is 200% or more (Yes in step S22), the permutation editing process is performed because the jitter is too large and erroneous data editing may be performed. Without proceeding to step S50.

  Returning to step S14, when the MS data editing unit 35 determines that the start code D2 cannot be detected within the specified time range (No in step S14), the MS data editing unit 35 changes the specified time range (step S30).

  FIG. 14 is a diagram showing the positions on the specifications of the track 104a and the track 104b with respect to the magnetic stripe 102. FIG. The change of the specified time range will be described with reference to FIG.

  In the specification (standard), the track 104a and the track 104b with the full length L1 are written at the position L2 from the right end of the magnetic stripe 102 and the write start end position is at the magnetic stripe 102 with respect to the magnetic stripe 102 with the full length L. It is assumed that the position is L3 from the left end. The length from the SPS to the start code D2 is S1 as described above.

  As shown in FIG. 11B, when the end position of the track 104a and the track 104b is at the left end of the magnetic stripe 102, the detection time of the start code D2 is the latest. The time is (S1 + L3) / V.

  Conversely, as shown in FIG. 11C, when the start position of the track 104a and the track 104b is at the right end of the magnetic stripe 102, the detection time of the start code D2 is the earliest. The time is (S1-L2) / V.

  Therefore, the specified time setting unit 36 writes (writes) one of the magnetic stripes 102 by changing (expanding) the specified time range from (S1-L2) / V to (S1 + L3) / V. The start code D2 can be detected from the track 104a and the track 104b.

  In other words, the MS data editing unit 35 detects the start code D2 for the track 104a and the track 104b when the leading ends of the track 104a and the track 104b are located at one end of the magnetic stripe 102. Time ((S1-L2) / V), the start code D2 is detected for the track 104a and the track 104b when the rear ends of the track 104a and the track 104b are located at the other end of the magnetic stripe 102. In the range up to the second time ((S1 + L3) / V), the start code D2 is detected from the MS data.

  After changing the specified time range (step S30), the MS data editing unit 35 determines whether the jitter of the MS data is normal (within ± 50%) (step S32), and determines that the jitter is normal (step S32 Yes). The process proceeds to step S34.

  The MS data editing unit 35 detects the start code D2 within the changed specified time range, and determines whether the start code D2 has been detected (step S34). When the MS data editing unit 35 determines that the start code D2 has been detected (Yes in step S34), the MS data editing unit 35 performs additional data editing processing based on the bit position of the start code D2 (step S36). Then, the MS data editing unit 35 determines whether all the read bits are normal (step S20). Step S20 has already been described and will be omitted.

  If the MS data editing unit 35 determines that the start code D2 cannot be detected (No in step S34), the process proceeds to step S50.

  The process returns to step S32. When the MS data editing unit 35 determines that the jitter is not normal (No in step S32), the MS data editing unit 35 determines whether the jitter is 200% or more (step S40).

  If the MS data editing unit 35 determines that the jitter is 200% or more (step S40 Yes), the process proceeds to step S50.

  If the MS data editing unit 35 determines that the jitter is not 200% or more (No in step S40), the MS data editing unit 35 detects the start code D2 within the changed specified time range, and determines whether the start code D2 is detected (step S40). S42). If the MS data editing unit 35 determines that the start code D2 cannot be detected (No in step S42), the process proceeds to step S50.

  When the MS data editing unit 35 determines that the start code D2 has been detected (Yes in step S42), the permutation for editing the data according to the additional editing process using the start code D2 detected by changing the specified time range and the order of the magnetization transition lines Editing processing is performed (step S44).

  After the additional editing process / permutation editing process, it is determined whether all the read bits are normal (step S20). Step S20 has already been described and will be omitted.

  Proceed to FIG. 13B. When the reading on the outward path side has failed, the MS control unit 31 performs the reading of the return path side retry (step S50). Contrary to the forward side, the magnetic head 32 is moved from h4 to h1, the magnetic signal written in the magnetic stripe 102 is read by the magnetic head 32, and the read magnetic signal is binarized as MS data. It is stored in the memory 37.

  The MS data editing unit 35 detects the previous dummy D1 from the MS data, determines whether the previous dummy D1 has been detected (step S52), and determines that the previous dummy D1 has been detected (step S52 Yes), the process proceeds to step S14. The process described above is performed.

  When the MS control unit 31 determines that the previous dummy D1 cannot be detected by the MS data editing unit 35 (No in step S52), the MS control unit 31 performs a process of resetting the bankbook 100 in the MS unit 20 (step S54), and reads on the forward path side. Execute (step S56). If the bankbook 100 is set at a shifted position and cannot be read, it is solved by resetting.

  The MS data editing unit 35 detects the previous dummy D1 from the MS data, determines whether the previous dummy D1 has been detected (step S58), and determines that the previous dummy D1 has been detected (step S58 Yes), the process proceeds to step S14. The process described above is performed.

  When the MS control unit 31 determines that the front dummy D1 cannot be detected by the MS data editing unit 35 (No in step S58), the MS control unit 31 performs a return-side retry reading (step S60). The MS data editing unit 35 detects the previous dummy D1 from the MS data, and determines whether the previous dummy D1 has been detected (step S62). If it is determined that the previous dummy D1 has been detected (Yes in step S62), the process proceeds to step S14 and the above-described processing is performed.

  If the MS control unit 31 determines that the previous dummy D1 cannot be detected by the MS data editing unit 35 (No in step S62), the MS control unit 31 performs a process of resetting the passbook 100 (step S64), and executes reading on the forward path side (step S66). ).

  The MS data editing unit 35 detects the previous dummy D1 from the MS data, determines whether the previous dummy D1 has been detected (step S68), and determines that the previous dummy D1 has been detected (step S68 Yes), the process proceeds to step S14. The process described above is performed.

  If the MS control unit 31 determines that the front dummy D1 cannot be detected by the MS data editing unit 35 (No in step S68), the MS control unit 31 performs reading on the return path side (step S70).

  The MS data editing unit 35 detects the previous dummy D1 from the MS data, determines whether the previous dummy D1 has been detected (step S72), and determines that the previous dummy D1 has been detected (step S72 Yes), the process proceeds to step S14. The process described above is performed.

  When the MS control unit 31 determines that the previous dummy D1 cannot be detected by the MS data editing unit 35 (No in step S72), the MS control unit 31 notifies the ATM control unit 8 as a reading error (step S74) and ends the process.

  As described above, the start code is initially detected within the specified time range, and if it cannot be detected within the specified time range, additional editing processing is performed to change and extend the specified time range. In addition, it is possible to read a passbook recorded at a location outside the specification without delaying the data editing processing time for most passbooks. Thereby, the range of compatibility between apparatuses and between manufacturers can be further expanded.

  In addition, since the change range of the specified time is set with the track having the entire length written in the magnetic stripe range as the limit, the range of the specified time is unnecessarily widened and processing time is not delayed.

  In addition, when the jitter is large with respect to the data recorded by the NRZI method, data with a large jitter can be read by performing the permutation editing process. The permutation editing process can be applied alone without being combined with the additional editing process.
