Description

  The present invention relates to a card issuing process for writing and issuing information on a magnetic card and a card receiving process for receiving and reading information from a magnetic card possessed by a user.

  As a device for processing a magnetic card, there is a magnetic card issuing device for writing predetermined information on a magnetic card and issuing the card. When the magnetic card issuing device receives, for example, character data (character information) indicating the card user's identification information from the host device, the control data of the current passed through the magnetic write head to magnetically record the character data on the magnetic card Convert to Information is written (magnetically recorded) to the magnetic stripe of the magnetic card by passing a current through the magnetic write head based on the converted current control data. After writing, information is read from the magnetic stripe of the magnetic card with a magnetic reading head, and the read information is converted into character data. Then, it is determined whether or not the information written on the magnetic card is normal based on the result of collating the converted character data with the character data to be written, that is, the character data received from the host device. If it is determined that the information written on the magnetic card is normal, the magnetic card is issued. On the other hand, when it is determined that the written information is not normal, the magnetic card is discarded, and writing of information to the new magnetic card and normal determination of the written information are performed as described above.

  Further, as a device for processing a magnetic card, there is a magnetic card receiving device that receives a magnetic card possessed by a user and reads and writes information. When the magnetic card is inserted into the magnetic card by the user, the magnetic card receiving device reads information from the magnetic stripe of the magnetic card with a magnetic reading head and converts the read information into character data. At this time, if the conversion to the character data can be performed normally, the information recorded on the magnetic card is normal, and the converted character data is transmitted to the host device. On the other hand, if the conversion to character data cannot be performed normally, the information recorded on the magnetic card is not normal, and the magnetic card is collected or returned. In addition, the reading condition by the magnetic reading head may be changed and information may be read from the magnetic card again.

  When it is determined that the recording information of the magnetic card is normal and the converted character data is transmitted to the host device, the magnetic card accepting device receives the balance information from the host device if the host device is an automatic cash transaction device, for example. Character data indicating such as is received. Then, after the received character data is converted into control data of current to be passed through the magnetic write head, information is written to the magnetic stripe of the magnetic card by passing current through the magnetic write head based on the converted current control data. After writing, information is read from the magnetic stripe of the magnetic card with a magnetic reading head, and the read information is converted into character data. Then, it is determined whether or not the information written on the magnetic card is normal based on the result of comparing the converted character data with the character data to be written. If it is determined that the information written on the magnetic card is normal, the magnetic card is returned. On the other hand, when it is determined that the written information is not normal, the magnetic card is collected or returned.

  In addition, after writing information on the magnetic card as described above, the technology for checking whether the information written on the magnetic card is normal by comparing the information read from the magnetic card with the information to be written on the magnetic card Is described, for example, in Patent Document 1 below. In addition, when the information recorded on the magnetic card cannot be read normally, a technique for changing the reading conditions by the magnetic reading head and reading the information from the magnetic card again is described in, for example, Patent Document 2 below. Yes.

  There is a demand from a provider who provides various services using a magnetic card as a medium so that the card issuing process and the card receiving process described above can be performed by a single device. In addition to this demand, when issuing a magnetic card, given that the magnetic card is used for a long time after issuance, predetermined information is reliably recorded on the magnetic stripe with a predetermined magnetic force, There is a desire to issue only a magnetic card with high magnetic recording performance in which the stripes are not scratched or soiled. Furthermore, when accepting a magnetic card, even if it is a magnetic card whose magnetic recording performance has deteriorated due to scratches etc. on the magnetic stripe or deterioration of the magnetic stripe due to long-term use, it should be accepted as much as possible There is a desire to perform predetermined information processing. However, in order to meet the above-mentioned demand, when the card issuing process and the card receiving process are performed by one apparatus, it is also strictly determined whether the information on the magnetic card is normal in both processes. Only a magnetic card with high magnetic recording performance can be issued when the card is issued, but there is a possibility that predetermined information processing cannot be normally performed on a magnetic card with a reduced magnetic recording performance when the card is received. In addition, if the determination of whether or not the information on the magnetic card is normal is performed in the same manner in both processes, predetermined information processing can be normally performed even on a magnetic card whose magnetic recording performance has deteriorated when the card is received. When a card is issued, there is a possibility that a magnetic card having a low magnetic recording performance may be issued.

  The present invention solves the above problems at the same time, and the problem is that only a magnetic card with high magnetic recording performance can be issued, and even a magnetic card with reduced magnetic recording performance is accepted. An object of the present invention is to provide a magnetic card issuance / acceptance device that can process normally.

  The present invention relates to a card issuing process for writing information to a magnetic card for issue by a writing means and issuing the magnetic card, and reading information to the received magnetic card by a reading means or writing information by a writing means. A magnetic card issuance accepting device that performs a card accepting process for returning the magnetic card and before writing information to the magnetic card by the writing means, based on the information read from the magnetic card by the reading means. After determining whether the information recorded in advance on the card is normal and writing the information on the magnetic card, the information is written on the magnetic card based on the written information and the information read from the magnetic card by the reading means after writing. A discriminating means for discriminating whether or not the information is normal, and the discriminating means It is determined whether or not the information on the magnetic card is normal using the first standard, and whether or not the information on the magnetic card is normal is determined using a second standard lower than the first standard during the card acceptance process. To do.

  As described above, in the card issuing process, after writing information on the magnetic card, it is strictly determined whether the information written on the magnetic card using the first reference higher than the second reference is normal. It is possible to issue only a magnetic card with high magnetic recording performance. Also, during the card acceptance process, before writing information to the magnetic card, the card issuance is performed to determine whether or not the information recorded in advance on the magnetic card is normal using the second reference lower than the first reference. It can be performed more relaxed than at the time of processing, and after writing information, the determination whether the information written on the magnetic card using the second reference is normal is more relaxed than at the time of card issuing processing. Even a magnetic card with reduced magnetic recording performance can be received and processed normally.

  In the embodiment of the present invention, the writing means includes a writing information converting means for converting the character data into data that can be magnetically recorded on the magnetic card, and magnetically stores information on the magnetic card based on the data converted by the writing information converting means. The magnetic reading head comprises a magnetic writing head for recording and writing, and the reading means includes a magnetic reading head for reading data magnetically recorded on the magnetic card, and a reading information converting means for converting the data read by the magnetic reading head into character data. It is configured. Further, the reference used by the discriminating means is generated in the process of converting the information read by the read information converting means to the character data and the reference regarding the level of the voltage output when the magnetic read head reads the information from the magnetic card. Each is set by tightening or loosening a reference for the jitter level of the pulse waveform data. Then, the discriminating means reads the information read from the magnetic card by the magnetic read head after the magnetic write head writes information to the magnetic card, and the read information converting means converts the data to character data. Whether or not the information on the magnetic card is normal based on the result of whether or not the conversion was successful and the character data after conversion is the same as the character data before writing to the magnetic card Is determined.

  As described above, after the information is written to the magnetic card during the card issuing process, the information read from the magnetic card can be normally converted into character data satisfying the strictly set first standard, and the conversion When the later character data matches the character data before writing to the magnetic card, it is determined that the information written on the magnetic card is normal, so that the magnetic recording performance is high and the magnetic Only cards can be issued. In addition, after the information is written to the magnetic card during the card acceptance process, the information read from the magnetic card can be normally converted into character data satisfying the second standard set loosely, and the converted character data If the data matches the character data before being written to the magnetic card, the information written on the magnetic card is determined to be normal, so even if the magnetic card has a reduced magnetic recording performance, the information can be accurately received. It becomes possible to return it after writing it.

  Furthermore, in the embodiment of the present invention, after the information is written to the magnetic card by the writing means during the card reception process, the determining means determines whether the information on the magnetic card is normal using the second reference, Before writing information to the magnetic card, it is determined whether or not the information on the magnetic card is normal by using a third reference lower than the second reference.

  As described above, at the time of card acceptance processing, before writing information to the magnetic card, whether or not the information recorded on the magnetic card is normal using the third reference lower than the second reference. The discrimination can be performed more relaxed than after the information is written, and it is possible to accept more magnetic cards having a deteriorated magnetic recording performance and write the information. After the information is written on the magnetic card, it is determined more strictly whether the information written on the magnetic card is normal using the second reference higher than the third reference than before the information is written. It is possible to determine and collect or return the received magnetic card whose information cannot be written correctly.

  According to the present invention, at the time of card issuance processing, by using the first reference higher than the second reference, it is strictly determined whether or not the information on the magnetic card is normal, and the magnetic recording performance is high. It is possible to issue only cards, and at the time of card acceptance processing, the use of a second standard lower than the first standard makes it easier to determine whether the information on the magnetic card is normal or not than during card issuance processing. Thus, even a magnetic card with reduced magnetic recording performance can be received and processed normally.

  FIG. 3 is a diagram for explaining a process of conversion of read information by the read information conversion unit 13. In FIG. 3, when information is read from the magnetic card 2 by the magnetic read head 5 described above, a signal output from the magnetic read head 5 to the read information conversion unit 13 is as shown in FIG. It is an analog signal representing a change in voltage according to a change in magnetic force of the magnetic card 2. In FIG. 3A, the output voltage waveform of the magnetic read head 5 is shown with the time t on the horizontal axis and the voltage value V on the vertical axis. The read information converter 13 samples the output voltage signal at a predetermined interval and converts it into digital voltage waveform data shown in FIG. Next, peak values (+ V side and −V side) of the voltage waveform data are detected, and converted into pulse waveform data including a pulse train as shown in FIG. 3C according to the interval between the detected peak values. . Then, the rise and fall of each pulse of the pulse waveform data is detected, and when there is a rise or fall at the beginning, end, and middle of the interval W substantially equal to the specified interval Wa, “1”, the beginning of the interval W When there is a rise or fall only at the end, it is judged as “0” and converted into bit data that is logical data of “0” and “1” as shown in FIG. Finally, the bit data is read according to a predetermined format and converted into character data as character information as shown in FIG.

  FIG. 4 is a diagram showing a reading information inspection standard. The read information inspection reference table T shown in FIG. 4A is stored in the storage unit 12 described above, and shows three references, reference A, reference B, and reference C, respectively. Each reference A to C is generated in the process in which the read information conversion unit 13 converts the read information into character data, and the reference related to the level of the output voltage output when the magnetic read head 5 reads information from the magnetic card 2. Each of the pulse waveform data is set by stricter or less strict reference with respect to the jitter level of the pulse waveform data. As shown in FIG. 4 (b), the reference A is the highest (most severe), the reference B is the next highest, and the reference C is the lowest (most loose) as shown in FIG. It has become. The control unit 11 described above is output from the read head 5 using any of the criteria A to C when the read information conversion unit 13 converts the information read from the magnetic card 2 by the magnetic read head 5 into character data. The level of the incoming output voltage and the jitter level of the pulse waveform data generated by converting the output voltage are inspected. Specifically, in the case of the card issuance process, the reference voltage A is used and the output voltage level (the amplitude of the output voltage) of the magnetic read head 5 is set to the upper and lower specified values Va and Vb shown in FIG. Jitter at each interval W of pulse waveform data representing 1-bit data of “0” or “1” shown in FIG. It is checked whether data whose level (an error with respect to the specified interval Wa) is 10% or more is less than 1 bit. After the information is written at the time of the card reception process, the reference B is used to check whether the output voltage level of the magnetic read head 5 is 70% or more, and the jitter level at each interval W of the pulse waveform data. It is checked whether or not the data having 20% or more is less than 10 bits. Before writing information at the time of card acceptance processing, it is checked whether the output voltage level of the magnetic read head 5 is 10% or more using the reference C, and the jitter level at each interval W of the pulse waveform data. It is checked whether or not data having a value of 30% or more is less than 10 bits.

  FIG. 5 is a diagram for explaining the character data. In FIGS. 5A and 5B, SS (Start Sentinel) is the head control code, ES (End Sentinel) is the tail control code, and these are all composed of 5-bit bit data of “1”. . CD1 to CD # are character data one by one, and each character data CD1 to CD # includes 5-bit bit data representing characters such as alphanumeric characters and parity (Parity) for each character data CD1 to CD #. And 1-bit bit data representing VRC (Vertical Redundancy Check). Note that VRC is defined as “1” if the number of “1” of 5-bit bit data representing a character is an even number, and “0” if it is an odd number. LRC (Longitudinal Redundancy Check) is the parity of the entire data, and is defined as “1” if the number of “1” of all bit data is an even number, and “0” if it is an odd number.

  When the information read from the magnetic card 2 by the magnetic read head 5 is read and converted by the information conversion unit 13 into character data, the control unit 11 inspects the magnetic format of the converted character data. Specifically, the control code SS exists at the beginning of the data, the control code ES exists immediately before the LRC, the VRC that is the parity for each of the character data CD1 to CD # is correct, and the parity of the entire data Check whether the LRC is correct. The control unit 11 converts the character data by the write information conversion unit 14 and writes it on the magnetic card 2 by the magnetic write head 6, and then reads the information read from the magnetic card 2 by the magnetic read head 5. In addition to the above-described inspection of the character data after conversion, whether the character data after conversion and the character data (write information) to be written on the magnetic card 2 coincide with each other. inspect. Specifically, it is inspected whether the total capacity of the two character data matches and whether each of the CD1 to CD # of the two character data matches.

  6 to 10 are flowcharts showing an operation procedure of the magnetic card issue / acceptance device 10. Each process is executed by the control unit 11 (specifically, a CPU provided in the control unit 11). 6 shows the main process, FIGS. 7A and 7B show the details of the card reception process, FIGS. 8A and 8B show the details of the card issue process, and FIG. 9 shows the details of the read information inspection process. FIG. 10 shows details of the card collection processing.

  In FIG. 6, when the magnetic card 2 is inserted from the insertion / ejection port 1b (FIG. 1) of the magnetic card issuance / acceptance device 10, the first sensor 3a (FIG. 1) detects the magnetic card 2 from the OFF state. Since it is switched to the ON state (step S1: YES), upon receiving this switching signal, the control unit 11 executes card acceptance processing according to the flowcharts of FIGS. 7A and 7B (step S2). 7A, first, the control unit 11 starts normal rotation driving of the card transport motor 15 (FIG. 2) (step S11), and rotates the roller 4 (FIG. 1) in the normal direction, thereby causing the magnetic card 2 to rotate. Is conveyed in the F direction inside the main body 1a. After a while, when the first sensor 3a stops detecting the magnetic card 2 and switches from the ON state to the OFF state (step S12: YES), the control unit 11 determines that the magnetic card 2 is the magnetic read head 5 (FIG. 1). ), And reading of information from the magnetic card 2 by the magnetic reading head 5 is started (step S13). When the second sensor 3b (FIG. 1) described above detects the magnetic card 2 and switches from the OFF state to the ON state (step S14: YES), the control unit 11 causes the magnetic card 2 to contact the magnetic read head 5. It is determined that the sheet has been transported to a position where it no longer exists, and reading of information from the magnetic card 2 by the magnetic reading head 5 is stopped (step S15). Immediately after this, the controller 11 stops the forward rotation drive of the motor 15 (step S16), stops the forward rotation of the roller 4, and stops the conveyance of the magnetic card 2.

  When the forward rotation driving of the motor 15 is stopped, the control unit 11 converts the information read from the magnetic card 2 by the magnetic reading head 5 into character data by the read information conversion unit 13 (FIG. 2) (step). S17). After the conversion, the control unit 11 executes the read information inspection process according to the flowchart of FIG. 9 using the lowest reference C (FIG. 4) described above (step S18). In FIG. 9, the control unit 11 first checks the magnetic format of the converted character data (step S81). Here, as described above, it is checked whether the character data includes the control code SS or ES and whether the parity VRC or LRC is correct. Next, the control unit 11 inspects the jitter level of the pulse waveform data generated in the conversion process up to the character data (step S82). Here, as described above, the reference C is used to check whether or not the data of which the jitter level of the pulse waveform data is 30% or more is less than 10 bits. Then, the control unit 11 inspects the output voltage level of the magnetic read head 5 when information is read from the magnetic card 2 (step S83). Here, the reference C is used as described above to determine the output voltage level of the magnetic read head 5. Inspect whether the output voltage level is 10% or more. When the output voltage level is inspected, the control unit 11 has not yet written information to the magnetic card 2 (step S84: NO), and thus ends the read information inspection process and proceeds to step S19 in FIG. 7A.

  When the process proceeds to step S19 in FIG. 7A, the control unit 11 determines whether or not the conversion of the read information into the character data has been normally performed. In the immediately preceding read information inspection process (step S18), the magnetic format of the character data is normal (both SS and ES are present, both VRC and LRC are correct), and the jitter level of the character data satisfies the reference C (jitter level). If the output voltage level of the magnetic read head 5 also satisfies the standard C (the output voltage level is 10% or more), the controller 11 reads the read information. It is determined that the conversion into character data has been performed normally (step S19: YES). If it discriminate | determines in this way, the control part 11 will discriminate | determine that the information previously recorded on the magnetic card 2 is normal (step S20), and will convert the character data after conversion by the above-mentioned communication part 17 (FIG. 2). It transmits to the apparatus 30 (step S21), and moves to step S26 of FIG. 7B.

  In contrast to the above, for example, the magnetic stripe of the inserted magnetic card 2 has very large scratches or dirt, or the magnetic force of the magnetic stripe is very small, so that the magnetic recording performance of the magnetic card 2 is remarkably deteriorated. In the immediately preceding read information inspection process (step S18), the magnetic format of the character data is not normal (SS or ES is absent or one or both VRC and LRC are both) Is not correct), the jitter level of the character data does not satisfy the standard C (data with a jitter level of 30% or more is 10 bits or more), or the output voltage level of the magnetic read head 5 satisfies the standard C If not (the output voltage level is less than 10%), the control unit 11 reads in step S19. Take conversion to character data information is determined to not be normally performed (step S19: NO). If it discriminate | determines in this way, the control part 11 will discriminate | determine that the information previously recorded on the magnetic card 2 is abnormal (step S22), and the communication part 17 will indicate that the recording information on the magnetic card 2 is abnormal. The host device 30 is notified (step S23). After the notification, if the command to collect the magnetic card 2 is not received from the host device 30 by the communication unit 17 (step S24: NO), the control unit 11 proceeds to step S26 in FIG. 7B. On the other hand, when a command for collecting the magnetic card 2 is received from the host device 30 (step S24: YES), the control unit 11 executes a card collection process according to the flowchart of FIG. 10 (step S25). Note that the collection command for the magnetic card 2 may be received in advance from the host device 30 before notifying the host device 30 of an abnormality in the recording information of the magnetic card 2 but before notifying the host device 30. In FIG. 10, the control unit 11 first drives the motor 15 to rotate forward (step S91), rotates the roller 4 forward, and transports the magnetic card 2 in the F direction. Then, after the above-described third sensor 3c (FIG. 1) once detects the magnetic card 2 and switches from the OFF state to the ON state, the magnetic card 2 is not detected and switches to the OFF state (step S92: YES). The control unit 11 determines that the magnetic card 2 has been collected by the card collection unit 9 (the two-dot chain line state in FIG. 1), stops the forward rotation of the motor 15 (step S93), and the roller 4 Is stopped, and the card collecting process and the card receiving process for the magnetic card 2 are terminated.

  7B, when the character data to be written on the magnetic card 2 is received from the host device 30 by the communication unit 17 (step S26: YES), the control unit 11 converts the received character data into the above-described write information. The conversion unit 14 (FIG. 2) converts the control data into the current control data flowing in the magnetic write head 6 (FIG. 1) (step S27). Thereafter, the control unit 11 starts reverse rotation driving of the motor 15 (step S28), reversely rotates the roller 4, and conveys the magnetic card 2 in the B direction. Further, immediately after the start of the reverse drive of the motor 15, the control unit 11 starts writing information to the magnetic card 2 by the magnetic write head 6 based on the current control data converted by the write information conversion unit 14 in step S27. (Step S29). When the first sensor 3a detects the magnetic card 2 and switches from the OFF state to the ON state (step S30: YES), the control unit 11 is transported to a position where the magnetic card 2 does not come into contact with the magnetic write head 6. The writing of information to the magnetic card 2 by the magnetic writing head 6 is stopped (step S31). Immediately after this, the controller 11 stops the reverse drive of the motor 15 (step S32), stops the reverse rotation of the roller 4, and stops the conveyance of the magnetic card 2.

  When the reverse drive of the motor 15 is stopped, the controller 11 starts the forward drive of the motor 15 (step S33), rotates the roller 4 forward, transports the magnetic card 2 in the F direction, and then continues. Immediately, reading of information from the magnetic card 2 by the magnetic reading head 5 is started (step S34). When the second sensor 3b detects the magnetic card 2 and switches from the OFF state to the ON state (step S35: YES), the control unit 11 is transported to a position where the magnetic card 2 does not come into contact with the magnetic reading head 5. The reading of information from the magnetic card 2 by the magnetic reading head 5 is stopped (step S36). Immediately after this, the controller 11 stops the forward drive of the motor 15 (step S37), stops the forward rotation of the roller 4, and stops the conveyance of the magnetic card 2.

  When the forward rotation driving of the motor 15 is stopped, the control unit 11 converts the information read from the magnetic card 2 by the magnetic reading head 5 into character data by the read information conversion unit 13 (step S38). After the conversion, the control unit 11 executes the read information inspection process according to the flowchart of FIG. 9 using the reference B (FIG. 4) described above (step S39). In FIG. 9, the control unit 11 first checks the magnetic format of the character data converted as described above (step S81). Next, the control unit 11 inspects the jitter level of the pulse waveform data generated in the conversion process up to the character data (step S82). Here, as described above, the reference B is used to check whether or not the data whose pulse waveform data jitter level is 20% or more is less than 10 bits. Then, the control unit 11 checks the output voltage level of the magnetic read head 5 (step S83). Here, as described above, using the reference B, is the output voltage level of the magnetic read head 5 70% or higher? Inspect. When the output voltage level is inspected, the control unit 11 has written information to the magnetic card 2 (step S84: YES), so that the entire capacity of the converted character data and the character data to be written to the magnetic card 2 are obtained. It is inspected whether the total capacity of the (character data received from the host device 30) matches (step S85). Further, the control unit 11 has one data CD1 to CD # (FIG. 5) of the converted character data and one data CD1 to CD # (FIG. 5) of the character data to be written to the magnetic card 2. It is inspected whether it has done (step S86). After the inspection, the control unit 11 ends the read information inspection process and proceeds to step S40 in FIG. 7B.

  When the process proceeds to step S40 in FIG. 7B, the control unit 11 determines whether or not the conversion of the read information into the character data has been normally performed. In the immediately preceding read information inspection process (step S39), the magnetic format of the character data is normal and the jitter level of the character data satisfies the standard B (data with a jitter level of 20% or more is less than 10 bits), When the output voltage level of the magnetic read head 5 also satisfies the reference B (the output voltage level is 70% or more), the control unit 11 determines that the conversion of the read information into character data has been successfully performed ( Step S40: YES). Subsequently, the control unit 11 determines whether or not the character data read from the magnetic card 2 matches the character data to be written to the magnetic card 2 (step S41). In the immediately preceding read information inspection process (step S39), the converted character data and the character data to be written have the same capacity, and the converted character data and the character data to be written CD1 to CD # Are matched with each other, the control unit 11 determines that the read character data matches the character data to be written (step S41: YES). If it judges in this way, the control part 11 will discriminate | determine that the information written in the magnetic card 2 is normal (step S42), and will start reverse rotation drive of the motor 15 in order to return the magnetic card 2 (step S42). In step S43, the roller 4 is rotated in the reverse direction, and the magnetic card 2 is conveyed in the B direction toward the insertion / discharge port 1b. Then, once the first sensor 3a detects the magnetic card 2 and switches from the OFF state to the ON state, when the magnetic card 2 is not detected and switches to the OFF state (step S44: YES), the control unit 11 It is determined that the magnetic card 2 has been ejected to the insertion / ejection slot 1b and returned, and the reverse drive of the motor 15 is stopped (step S45), the reverse rotation of the roller 4 is stopped, and the card acceptance process is terminated.

  In contrast to the above, due to the fact that the magnetic recording performance of the inserted magnetic card 2 is remarkably deteriorated, in the read information inspection process in step S39, the character data magnetic format is not normal or the character data jitter The level does not satisfy the standard B (data with a jitter level of 20% or more is 10 bits or more), the output voltage level of the magnetic read head 5 does not satisfy the standard B (the output voltage level is 70%) If it is less, the control unit 11 determines in step S40 that conversion of the read information into character data has not been performed normally (step S40: NO), and the information written in the magnetic card 2 is abnormal. It discriminate | determines (step S46). Even if it is determined in step S40 that the conversion of the read information into the character data has been successfully performed (step S40: YES), the character data to be written and the converted character data are read in the read information inspection process in step S39. If the total capacity does not match or there is data that does not match between the converted character data and the data CD1 to CD # of the character data to be written, the control unit 11 reads the read character data. Is not consistent with the character data to be written (step S41: NO), it is determined that the information written on the magnetic card 2 is abnormal (step S46). If it discriminate | determines in this way, the control part 11 will notify the high-order apparatus 30 by the communication part 17 that the information written in the magnetic card 2 is abnormal (step S47). After the notification, if the command to collect the magnetic card 2 is not received from the host device 30 by the communication unit 17 (step S48: NO), the control unit 11 performs steps S43 to S45 in the same procedure as described above. Execute, return the magnetic card 2, and end the card acceptance process. Further, when a command for collecting the magnetic card 2 is received from the host device 30 in step S48 (step S48: YES), the control unit 11 executes the card collection process according to the flowchart of FIG. 10 in the same procedure as described above. (Step S49), the magnetic card 2 is collected, and the card receiving process is terminated.

  On the other hand, in FIG. 6, the magnetic card 2 issuance command from the host device 30 to the magnetic card issuance acceptance device 10 and the card user writing to the magnetic card 2 in a state where the magnetic card 2 is not inserted from the insertion / ejection port 1 b. When the character data indicating the identification information or the like is transmitted, the control unit 11 remains in the OFF state without the first sensor 3a detecting the magnetic card 2 (step S1: NO), and issues the magnetic card 2 issue command and the magnetic card. 2 is received from the higher-level device 30 by the communication unit 17 (step S3: YES), card issuing processing is executed according to the flowcharts of FIGS. 8A and 8B (step S4). In FIG. 8A, the control unit 11 first converts the character data received from the higher-level device 30 into control data of current to be passed through the magnetic write head 6 by the write information conversion unit 14 (step S51). Next, the control unit 11 starts normal rotation driving of the card supply table moving motor 16 (FIG. 2) (step S52), and rotates the roller 8 (FIG. 1) in the normal direction to thereby rotate the card card. The supply stand 7 (FIG. 1) is raised in the U direction. When the above-described fourth sensor 3d (FIG. 1) detects the magnetic card 2 for issuance on the card supply base 7 and switches from the OFF state to the ON state (step S53: YES), the control unit 11 issues the issuance. It is determined that the magnetic card 2 for use has been supplied to a position that can be transported by the roller 4, the forward drive of the motor 16 is stopped (step S 54), the forward rotation of the roller 8 is stopped, and the card supply table 7 is raised. Stop.

  When the forward drive of the motor 16 is stopped, the control unit 11 starts the reverse drive of the motor 15 (step S55), rotates the roller 4 in the reverse direction, and conveys the magnetic card 2 in the B direction. After a while, the second sensor 3b once detects the magnetic card 2 and switches from the OFF state to the ON state, and then stops detecting the magnetic card 2 and switches to the OFF state (step S56: YES). Determines that the magnetic card 2 has been transported to a position where it comes into contact with the magnetic write head 6, and based on the current control data converted by the write information conversion unit 14 in step S51, the information on the magnetic card 2 by the magnetic write head 6 is transferred. Writing is started (step S57). When the first sensor 3a detects the magnetic card 2 and switches from the OFF state to the ON state (step S58: YES), the controller 11 is transported to a position where the magnetic card 2 does not come into contact with the magnetic write head 6. The writing of information to the magnetic card 2 by the magnetic writing head 6 is stopped (step S59). Immediately after this, the controller 11 stops the reverse drive of the motor 15 (step S60), stops the reverse rotation of the roller 4, and stops the conveyance of the magnetic card 2.

  When the reverse drive of the motor 15 is stopped, the control unit 11 starts the forward drive of the motor 15 (step S61), rotates the roller 4 forward, transports the magnetic card 2 in the F direction, and then continues. Immediately, reading of information from the magnetic card 2 by the magnetic reading head 5 is started (step S62). When the second sensor 3b detects the magnetic card 2 and switches from the OFF state to the ON state (step S63: YES), the control unit 11 is transported to a position where the magnetic card 2 does not come into contact with the magnetic reading head 5. The reading of information from the magnetic card 2 by the magnetic reading head 5 is stopped (step S64). Immediately after this, the controller 11 stops the forward drive of the motor 15 (step S65), stops the forward rotation of the roller 4, and stops the conveyance of the magnetic card 2.

  When the forward rotation driving of the motor 15 is stopped, the control unit 11 converts the information read from the magnetic card 2 by the magnetic reading head 5 into character data by the reading information conversion unit 13 (step S66 in FIG. 8B). After the conversion, the control unit 11 executes the read information inspection process according to the flowchart of FIG. 9 using the highest reference A (FIG. 4) described above (step S67). In FIG. 9, the control unit 11 first checks the magnetic format of the character data converted as described above (step S81). Next, the control unit 11 inspects the jitter level of the pulse waveform data generated in the conversion process up to the character data (step S82). Here, as described above, the reference A is used to check whether or not the data whose pulse waveform data has a jitter level of 10% or more is less than 1 bit. Then, the control unit 11 inspects the output voltage level of the magnetic read head 5 (step S83). Here, as described above, using the reference A, is the output voltage level of the magnetic read head 5 90% or more? Inspect. When the output voltage level is inspected, the control unit 11 has written information to the magnetic card 2 (step S84: YES), so that the entire capacity of the converted character data and the character data to be written to the magnetic card 2 are obtained. It is inspected whether or not the total capacity is equal (step S85). Further, the control unit 11 inspects whether the data CD1 to CD # of the character data after conversion and the data CD1 to CD # of the character data to be written on the magnetic card 2 match each other (step) S86). After the inspection, the control unit 11 ends the read information inspection process and proceeds to step S68 in FIG. 8B.

  When the process proceeds to step S68 in FIG. 8B, the control unit 11 determines whether or not the conversion of the read information into the character data has been normally performed. In the immediately preceding read information inspection process (step S67), the magnetic format of the character data is normal, and the jitter level of the character data satisfies the standard A (data with a jitter level of 10% or more is less than 1 bit), When the output voltage level of the magnetic read head 5 also satisfies the reference A (the output voltage level is 90% or more), the control unit 11 determines that the conversion of the read information into character data has been successfully performed ( Step S68: YES). Subsequently, the control unit 11 determines whether or not the character data read from the magnetic card 2 matches the character data to be written to the magnetic card 2 (step S69). In the immediately preceding reading information inspection process (step S67), the converted character data and the character data to be written have the same capacity, and the converted character data and the character data to be written CD1 to CD # Are matched, the control unit 11 determines that the read character data matches the character data to be written (step S69: YES). If it judges in this way, the control part 11 will discriminate | determine that the information written in the magnetic card 2 is normal (step S70), and will start reverse rotation drive of the motor 15 in order to issue the magnetic card 2 (step S70). S71), the roller 4 is rotated in the reverse direction, and the magnetic card 2 is conveyed in the B direction toward the insertion / discharge port 1b. Then, once the first sensor 3a detects the magnetic card 2 and switches from the OFF state to the ON state, when the magnetic card 2 is not detected and switches to the OFF state (step S72: YES), the control unit 11 It is determined that the magnetic card 2 has been ejected to the insertion / ejection slot 1b, and the reverse drive of the motor 15 is stopped (step S73), the reverse rotation of the roller 4 is stopped, and the card issuance process is terminated.

  In contrast to the above, for example, because the magnetic stripe of the magnetic card 2 for issue is scratched or dirty, or the magnetic force of the magnetic stripe is reduced, the magnetic recording performance of the magnetic card 2 is not high. In the reading information inspection process in step S67, the magnetic format of the character data is not normal, or the jitter level of the character data does not satisfy the standard A (data having a jitter level of 10% or more is 1 bit or more). If the output voltage level of the magnetic read head 5 does not satisfy the reference A (the output voltage level is less than 90%), the control unit 11 normally converts the read information into character data in step S68. It is judged that it was not possible (step S68: NO), and the information written in the magnetic card 2 is abnormal. Determine (step S74). Even if it is determined in step S68 that the conversion of the read information into the character data has been successfully performed (step S68: YES), the character data to be written and the converted character data are read in the read information inspection process in step S67. If the total capacity does not match or there is data that does not match between the converted character data and the data CD1 to CD # of the character data to be written, the control unit 11 reads the read character data. Is not coincident with the character data to be written (step S69: NO), it is determined that the information written to the magnetic card 2 is abnormal (step S74). If it discriminate | determines in this way, the control part 11 will perform a card | curd collection | recovery process according to the flowchart of FIG. 10 in the same procedure as mentioned above (step S75), and will collect | recover the magnetic cards 2. FIG. Thereafter, if the number of magnetic cards 2 for issuance collected continuously is less than the predetermined number (step S76: NO), the control unit 11 performs step of FIG. 8A to issue a new magnetic card 2. The process proceeds to S52, and each step is executed again from step S52 in the same procedure as described above. 8B, if the number of magnetic cards 2 for issuance collected continuously exceeds the predetermined number (step S76: YES), the control unit 11 indicates that an issue abnormality of the magnetic card 2 has occurred. Is notified to the host device 30 by the communication unit 17 (step S77), and the card issuing process is terminated without issuing the magnetic card 2.

  As in the procedure described above, after the information is written to the magnetic card 2 during the card issuing process, it is determined whether or not the information written to the magnetic card 2 is normal using the strictest reference A. Thus, the determination can be performed strictly. Therefore, when the information read from the magnetic card 2 satisfies the standard A and can be normally converted to character data, and the converted character data matches the character data before writing to the magnetic card 2, the magnetic card By determining that the information written in 2 is normal, it is possible to issue only the magnetic card 2 having high magnetic recording performance and accurately writing information. Further, at the time of card acceptance processing, before writing information to the magnetic card 2, it is determined whether or not the information recorded on the magnetic card 2 is normal using the reference C set lower than the reference A. The determination can be made more relaxed than the determination of information during the card issuance process. Therefore, when the information read from the magnetic card 2 satisfies the standard C and can be converted into character data normally, it is determined that the information recorded on the magnetic card 2 is normal, thereby reducing the magnetic recording performance. Even the magnetic card 2 that has been received can be received and information can be written. Further, after the information is written to the magnetic card 2 during the card acceptance process, it is determined whether the information written to the magnetic card 2 is normal using the reference B set lower than the reference A. The determination can also be made more relaxed than the determination of information during the card issuing process. Therefore, when the information read from the magnetic card 2 satisfies the standard B and can be normally converted to character data, and the converted character data matches the character data before writing to the magnetic card 2, the magnetic card By determining that the information written in 2 is normal, even the magnetic card 2 with reduced magnetic recording performance can be received and returned after the information is correctly written.

  Further, at the time of card reception processing, before writing information to the magnetic card 2, it is determined whether or not the information recorded in advance on the magnetic card 2 is normal using the reference C set lower than the reference B. Thus, the determination can be performed more relaxed than the determination after information is written to the magnetic card 2, and more magnetic cards 2 with reduced magnetic recording performance can be received and information can be written. . Then, after writing information to the magnetic card 2, it is determined whether or not the information written to the magnetic card 2 is normal using the reference B, so that the determination is made before writing the information to the magnetic card 2. It is possible to perform the process more strictly, and it is possible to determine and collect or return the received magnetic card 2 in which information cannot be written correctly.

  In the embodiment described above, the read information inspection process of FIG. 9 is exemplified after the conversion process for converting the information read from the magnetic card 2 to the character data, but the present invention is only this. For example, the read information inspection process may be started simultaneously with the conversion process of the read information, or may be started during the conversion process.

  Moreover, in the said embodiment, when returning the magnetic card 2 which was not able to process normally in a card reception process, the example which returned the magnetic card 2 to the insertion discharge port 1b as it is is given, but this invention does this. For example, the magnetic card record information that could not be processed normally is deleted, or information indicating that the record information is abnormal is written to the magnetic card and returned. You may make it do.

  Furthermore, in the said embodiment, the example which applied this invention to the magnetic card issue reception apparatus 10 to which the magnetic card 2 for issuing is automatically supplied by the card supply stand 7 provided in the main body inside 1a is given. However, the present invention is not limited to this, and a magnetic card issuance accepting device in which the magnetic card 2 for issuance is automatically supplied from a card supply unit provided in the host device 30, and the magnetic card 2 for issuance is inserted and discharged. It can be applied to a magnetic card issuance accepting device that is manually supplied from 1b, taken into the main body 1a, and released from the insertion / ejection port 1b after information recording.
