  2. Description of the Related Art Conventionally, a paper sheet counting apparatus for calculating the number of passbooks stored in a storage unit in a stacked state is known (see, for example, Patent Document 1). The paper sheet counting apparatus described in Patent Document 1 includes a reflective optical sensor having a light emitting element and a light receiving element. This optical sensor is movable in the thickness direction of the passbook accommodated in the accommodating portion. Further, the paper sheet counting apparatus described in Patent Document 1 is calculated by a sensor unit that receives a signal from an optical sensor, a control unit that processes the signal received by the sensor unit to calculate the number of passbooks, and a control unit. A notification unit that transmits the number of passbooks completed and an end status such as normal end or abnormal end to a higher-level device or the like.

JP 2011-65378 A

  When a bankbook set abnormality is notified to the control unit of the host device on which the paper sheet counting device described in Patent Document 1 is mounted, the subsequent processing is performed unless the bankbook stored in the storage unit is reset. There may be a set abnormality that cannot be performed, or there may be a minor set abnormality that can be performed properly without resetting the bankbook stored in the storage unit. There may be.

  However, the control unit of the host device on which the paper sheet counting device described in Patent Document 1 is mounted is notified of the set abnormality even when a slight set abnormality has occurred. Therefore, even if a minor set abnormality has occurred and it is not necessary to reset the passbook in the storage unit, the user of the host device is notified of the set abnormality in the storage unit. It is necessary to confirm the stored passbook. Even if it is not necessary to reset the bankbook in the storage unit, if the set abnormality is notified, the counting result of the bankbook is not notified to the host device. Processing for obtaining the counting result must be executed. Thus, it cannot be said that the convenience of the host device on which the paper sheet counting device described in Patent Document 1 is mounted is good.

The number information of the calculated card-like medium and the rank information that is the ranked rank information are sent to the control unit of the host device on which the card-like medium counting device is mounted. Characterized by trust.

  Further, in order to solve the above-described problem, the control method of the card-like medium counting device according to the present invention includes a medium accommodating unit that accommodates the card-like medium so as to overlap in the thickness direction of the card-like medium, and A sensor for calculating the number of card-like media accommodated and a movement for moving the sensor in the thickness direction of the card-like media when counting the card-like media along the end surface of the card-like media accommodated in the medium accommodating portion And a card-like medium counting device comprising a mechanism for calculating the number of card-like media accommodated in the medium accommodating portion based on the sensor signal and calculating the card-like shape based on the sensor signal. A first likelihood that is the certainty of the number of media, a second certainty that is the certainty that the type and shape of the card-like medium accommodated in the medium accommodating portion are correct, and the medium accommodating portion The first rank, which has a relatively high third likelihood, which is the certainty that the received card-like medium is stored in the correct state, and the second likelihood, the first likelihood is comparable to the first rank. And / or the third likelihood, the second rank is lower than the first rank, the first likelihood is lower than the first rank, and at least one of the second likelihood and the third likelihood Is ranked in at least three ranks with a third rank lower than the first rank, and the card-like medium count is calculated by calculating the number information of the card-like medium and the rank information that is the ranked rank information. It transmits to the control part of the high-order apparatus in which an apparatus is mounted, It is characterized by the above-mentioned.

  In the present invention, the number of card-like media stored in the medium storage unit is calculated based on the sensor signal, and the three probabilities of the first probability, the second probability, and the third probability are ranked. The rank is classified into at least three ranks of the first rank, the second rank, and the third rank, and the number information of the card-like medium and the rank information calculated are used. Certain rank information is transmitted to the control unit of the host device. Therefore, in the present invention, based on the rank information transmitted to the host device, it is possible to determine whether the host device really needs to check the card-like medium stored in the medium storage unit. become. For example, when rank information of the third rank is transmitted, the card-like medium accommodated in the medium accommodating portion is confirmed. When rank information of the second rank is transmitted, the medium accommodating portion is confirmed. It is possible to make a determination that the received card-like medium is not confirmed on the host device side. Also, in the present invention, the calculated card number information of the card-like medium is transmitted to the control unit of the host device together with the rank information regardless of the rank, so that it is accommodated in the medium accommodating unit. If the higher-level device determines that the card-like medium is not confirmed, it is possible to execute the processing of the higher-level device as it is. Therefore, in the present invention, it is possible to improve the usability of the host device on which the card-like medium counting device is mounted.

  In the present invention, for example, when the plurality of peaks of the signal level of the sensor signal exceed a predetermined first threshold, the control unit is arranged at a time interval between adjacent peaks exceeding the first threshold of the signal level of the sensor signal. A certain peak interval is calculated, and the number of card-like media accommodated in the media accommodating portion is calculated based on a comparison result between a reference value preset based on the thickness of the card-like medium to be counted and the peak interval. Calculate and rank at least three ranks.

In the present invention, for example, the control unit is a case where a plurality of peaks of the signal level of the sensor signal exceed a predetermined first threshold value, and a plurality of bottoms of the signal level of the sensor signal is a predetermined second. When the signal level of the sensor signal is equal to or less than the threshold value, the bottom interval, which is the time interval between adjacent bottoms that is equal to or less than the second threshold value, is calculated and preset based on the thickness of the card-like medium to be counted. Based on the comparison result between the reference value and the bottom interval , the number of card-like media stored in the medium storage unit is calculated, and at least three ranks are ranked.

  In the present invention, the control unit, when a plurality of peaks of the signal level of the sensor signal exceeds a predetermined first threshold, a peak that is a time interval between adjacent peaks of the signal level of the sensor signal exceeding the first threshold. When the intervals are calculated and the plurality of peaks of the signal level of the sensor signal exceed the first threshold value, and the plurality of bottoms of the signal level of the sensor signal is equal to or lower than the predetermined second threshold value, The bottom interval, which is the time interval between adjacent bottoms below the second threshold value of the signal level of the sensor signal, is calculated, and the signal level of the sensor signal is smaller than the first threshold value and the second threshold value when the card-like medium is detected by the sensor. Assuming that the average interval is the number obtained by dividing the total time interval, which is the time interval from the time when the predetermined third threshold value is exceeded to the time when the value falls below the third threshold value, by the number of peaks exceeding the first threshold value of the sensor signal When all of the intervals are within a predetermined first reference range, all of the bottom intervals are within a predetermined second reference range, and the average interval is within a predetermined third reference range, It is preferable that the number of peaks exceeding one threshold is calculated as the number of card-like media stored in the medium storage unit and ranked as the first rank.

  With this configuration, when the rank information of the first rank is transmitted to the host device, the first probability that is the probability of the number of card-like media, the type of the card-like media accommodated in the medium accommodating portion The second likelihood, which is the certainty that the shape is correct, and the third probability, which is the certainty that the card-like medium accommodated in the medium accommodating portion is accommodated in the correct state, are further increased. Therefore, when the rank information of the first rank is transmitted to the host device, the subsequent processing of the host device can be executed with peace of mind without checking the card-like medium stored in the medium storage unit. Become.

  In the present invention, for example, when at least one of the peak intervals is out of the first reference range and the peak interval out of the first reference range is equal to or less than a predetermined first reference value, at least one of the bottom intervals is In the case where at least one of the case where the bottom interval deviating from the second reference range and deviating from the second reference range is equal to or less than the predetermined second reference value and the average interval deviating from within the third reference range, The number of peaks exceeding the first threshold value of the sensor signal is calculated as the number of card-like media and ranked as the second rank. In this case, when ranked as the second rank, even if the peak interval is out of the first reference range, it is equal to or less than the first reference value, and the bottom interval is out of the second reference range. Since it is below the reference value, it is possible to make the first likelihood of the first rank and the first likelihood of the second rank more similar.

  In the present invention, the control unit, for example, when at least one of the peak intervals is out of the first reference range and the peak interval out of the first reference range exceeds the first reference value, and at least one of the bottom intervals is the second. The third rank is ranked in at least one of cases where the bottom interval that is out of the reference range and out of the second reference range exceeds the second reference value.

  In the present invention, the control unit sets a predetermined fourth threshold value when the peak interval exceeds the first reference value and the bottom of the signal level of the sensor signal at the peak interval is smaller than the first threshold value and the second threshold value. If it exceeds, a correction value calculated based on the peak interval exceeding the first reference value is added to the number of peaks exceeding the first threshold value of the sensor signal to calculate the number of card-like media. If the bottom interval exceeds the second reference value when it is less than or equal to one reference value, a correction value calculated based on the bottom interval exceeding the second reference value is added to the number of peaks exceeding the first threshold of the sensor signal When the peak interval exceeds the first reference value and the bottom of the signal level of the sensor signal at the peak interval is equal to or less than the fourth threshold value. It is preferable to calculate the number of peaks exceeding a first threshold value of the sensor signal as a number of card media. If comprised in this way, it will become possible to raise the 1st certainty (the certainty of the number of card-like media) at the time of ranking to the 3rd rank.

  In the present invention, the control unit is accommodated in the medium accommodating unit when, for example, the number of peaks exceeding the first threshold of the sensor signal is one and the total time interval is equal to or less than a predetermined third reference value. The number of card-like media is calculated as one and ranked first. In the present invention, for example, when the card-like medium is detected by the sensor and the signal level of the sensor signal does not exceed the third threshold value, the control unit sets the number of card-like media to be accommodated in the medium accommodating unit to zero. And rank with the first rank. In this case, even if the number of card-like media accommodated in the medium accommodating portion is one or zero, it is possible to appropriately calculate the number of card-like media accommodated in the medium accommodating portion. At the same time, it is possible to perform an appropriate ranking.

  In the present invention, the control unit is a case where the signal level of the sensor signal exceeds a predetermined third threshold value smaller than the first threshold value, and the peak of the signal level of the sensor signal when the sensor detects the card-like medium. Or the number of times that the signal level of the sensor signal exceeds the first threshold is one, and the signal level of the sensor signal is the third threshold when the sensor detects the card-like medium. When the total time interval, which is the time interval from exceeding the third threshold value to exceeding the third threshold, exceeds a predetermined third reference value, the first probability, the second probability, and the third probability are the third rank. As the number of card-like media, the total time interval is divided by a preset reference value based on the thickness of the card-like media to be counted. It is preferable to leave. If comprised in this way, the number information of a card-like medium will be transmitted to a high-order apparatus with the rank information of 4th rank in which 1st probability, 2nd probability, and 3rd probability are lower than 3rd rank. Is possible.

  In the present invention, the sensor is, for example, an optical sensor including a light emitting unit and a light receiving unit that receives light from the light emitting unit.

(Card number calculation method and ranking method)
FIG. 4 is a flowchart showing an example of a control flow of the card counting device 1 when calculating and ranking the number of cards 2 in the card counting device 1 shown in FIG. FIG. 5 is a flowchart showing an example of a processing flow in the number calculating / ranking step S5 of FIG. FIG. 6 is a diagram illustrating an example of the sensor signal SG when the control unit 25 illustrated in FIG. FIG. 7 is a diagram illustrating an example of the sensor signal SG when the control unit 25 illustrated in FIG. FIG. 8 is a diagram illustrating an example of the sensor signal SG when the control unit 25 illustrated in FIG. FIG. 9 is a diagram illustrating an example of the sensor signal SG when the control unit 25 illustrated in FIG.

  When calculating and ranking the number of cards 2 in the card counting device 1, first, the control unit 25 activates the motor of the moving mechanism 13 (step S1) and arranges it below the lowest card 2. The sensor 12 being moved is raised to obtain a sensor signal SG (step S2). The rise of the sensor 12 and the acquisition of the sensor signal SG are performed until the sensor 12 reaches a predetermined upper limit position (that is, performed until “Yes” in step S3), and when the sensor 12 reaches the upper limit position, The control unit 25 stops the motor of the moving mechanism 13 (step S4). Thereafter, the control unit 25 calculates and ranks the number of cards 2 based on the sensor signal SG acquired in step S2 (step S5), and calculates the calculated number information of the cards 2 and ranked rank information. Is transmitted to the host control unit 30 (step S6). Hereinafter, the calculation direction and ranking method of the number of cards 2 in step S5 will be specifically described.

  In step S5, the control unit 25 first determines whether or not the signal level of the sensor signal SG exceeds a predetermined threshold th0 (step S11). The threshold value th0 is set to a value about 0.3 to 0.6 times the peak value of the signal level of the sensor signal SG. In step S11, whether or not the signal level of the sensor signal SG exceeds the threshold value th0. It is determined whether or not the card 2 is accommodated in the card cassette 9. In step S11, when the signal level of the sensor signal SG exceeds the threshold th0, the control unit 25 specifies the peak and bottom of the signal level of the sensor signal SG (step S12).

  Thereafter, the control unit 25 determines whether or not the peak of the signal level of the sensor signal SG exceeds a predetermined threshold th1 that is larger than the threshold th0 (step S13). If the signal level peak exceeds the threshold th1 in step S13, the control unit 25 determines whether the number of peaks exceeding the threshold th1 is one (step S14). When the number of peaks exceeding the threshold th1 is two or more (plural) in step S14, the control unit 25 is the time interval between adjacent peaks exceeding the threshold th1 in the signal level of the sensor signal SG. The peak interval ti is calculated (step S15). For example, as illustrated in FIG. 6A, the control unit 25 calculates nine peak intervals t1 to t9.

  Further, in step S14, the number of peaks exceeding the threshold th1 is two or more, and two or more (plural) bottoms of the signal level of the sensor signal SG are equal to or less than the predetermined threshold th2. In addition, in step S15, the control unit 25 calculates a bottom interval Ti that is a time interval between adjacent bottoms of the signal level of the sensor signal SG that is equal to or less than the threshold th2. For example, as illustrated in FIG. 6A, the control unit 25 calculates eight bottom intervals T1 to T8. In the present embodiment, the threshold th2 is smaller than the threshold th1. The threshold th2 is larger than the threshold th0.

  Thereafter, the control unit 25 determines whether or not the peak interval ti and the bottom interval Ti calculated in step S15 are normal (step S16). Specifically, in step 16, the control unit 25 determines whether or not all of the peak intervals ti are within a predetermined first reference range, and all of the bottom intervals Ti are within a predetermined second reference range. It is determined whether or not there is. In this embodiment, a reference to be compared with the peak interval ti and the bottom interval Ti based on the thickness of the card 2 to be counted by the card counting device 1 (specifically, the normal thickness of the normal card 2). A value RV is preset. Specifically, a value obtained by dividing the thickness of the card 2 to be counted by the moving speed of the sensor 12 moved by the moving mechanism 13 is the reference value RV. The first reference range is a range from (a1 × RV) to (a2 × RV). For example, a1 is about 0.8 and a2 is about 1.2. Similarly, the second reference range is a range from (b1 × RV) to (b2 × RV), for example, b1 is about 0.8 and b2 is about 1.2.

  In step S16, when all of the peak intervals ti are within the first reference range and all of the bottom intervals Ti are within the second reference range, the control unit 25 determines that the signal level of the sensor signal SG is a threshold value. The total time interval W, which is the time interval from exceeding th0 to the threshold th0 or less, is calculated, and the average interval Wa, which is the number obtained by dividing the total time interval W by the number of peaks exceeding the threshold th1, is calculated ( Step S17). Thereafter, the control unit 25 determines whether or not the average interval Wa is normal (step S18). Specifically, in step 18, the control unit 25 determines whether or not the average interval Wa is within a predetermined third reference range. The third reference range is a range from (c1 × RV) to (c2 × RV). For example, c1 is about 0.8 and c2 is about 1.2.

  In step S18, when the average interval Wa is within the third reference range, the control unit 25 calculates the number of peaks exceeding the threshold value th1 of the sensor signal SG as the number of cards 2 accommodated in the card cassette 9. At the same time, it is determined as A rank and ranked as A rank (step S19). As described above, the control unit 25 determines that all of the peak intervals ti are in the first reference range, all of the bottom intervals Ti are in the second reference range, and the average interval Wa is in the third reference range. In this case, the number of peaks exceeding the threshold value th1 of the sensor signal SG is calculated as the number of cards 2 accommodated in the card cassette 9, and is ranked as A rank. For example, when the signal level of the sensor signal SG varies as shown in FIG. 6A, the control unit 25 determines the number of peaks exceeding the threshold th1 of the sensor signal SG in the card 2 accommodated in the card cassette 9. And the A rank.

  In step S16, when at least one of the peak intervals ti is out of the first reference range and / or when at least one of the bottom intervals Ti is out of the second reference range, the control unit 25 Whether the peak interval ti deviating from the first reference range is equal to or smaller than the predetermined first reference value RV1, and the bottom interval Ti deviating from the second reference range is equal to or smaller than the predetermined second reference value RV2. Is determined (step S21). The first reference value RV1 and the second reference value RV2 are values set based on the reference value RV. The first reference value RV1 is (d1 × RV), and for example, d1 is 1.6 to 1.7. Moreover, 2nd reference value RV2 is (d2 * RV), for example, d2 is 1.6-1.7.

  For example, as shown in FIG. 7, when the peak interval t7 is out of the first reference range and the bottom interval T7 is out of the second reference range, the control unit 25 determines that the peak interval t7 is the first in step S21. It is determined whether the reference value RV1 or less and the bottom interval T7 is less than or equal to the second reference value RV2. Further, for example, as shown in FIG. 8A, when the peak interval t6 is out of the first reference range and the bottom interval T6 is out of the second reference range, the control unit 25 determines that the peak in step S21 It is determined whether or not the interval t6 is less than or equal to the first reference value RV1 and the bottom interval T6 is less than or equal to the second reference value RV2. Also, as shown in FIG. 8B, when the peak interval t7 is out of the first reference range, the control unit 25 determines whether or not the peak interval t7 is equal to or less than the first reference value RV1 in step S21. Determine whether.

  In step S21, when the peak interval ti deviating from the first reference range is equal to or less than the first reference value RV1, and the bottom interval Ti deviating from the second reference range is equal to or less than the second reference value RV2. The control unit 25 calculates the number of peaks exceeding the threshold th1 of the sensor signal SG as the number of cards 2 accommodated in the card cassette 9, and determines the rank B to rank the rank B (step S22). ). That is, in this case, the control unit 25 has the first likelihood (the probability of the calculated number of cards 2) that is about the same as the A rank, but for example, the card 2 stored in the card cassette 9 Cards 2 of different types and shapes are mixed together, and the second probability (the certainty that the type and shape of the card 2 stored in the card cassette 9 is correct) is determined to be lower than the A rank. Rank B. Alternatively, in this case, the control unit 25 has a first likelihood that is about the same as the A rank. For example, the card 2 accommodated in the card cassette 9 is accommodated in a slanted state, It is determined that the third probability (the probability that the card 2 accommodated in the card cassette 9 is accommodated in the correct state) is lower than the A rank because dust or the like is sandwiched between the two. And rank B.

  In step S18, also when the average interval Wa is out of the third reference range, the process proceeds to step S22, and the control unit 25 sets the number of peaks exceeding the threshold value th1 of the sensor signal SG to the card cassette 9. It is calculated as the number of stored cards 2 and ranked as B rank. In other words, in this case, the control unit 25 has a first likelihood that is about the same as the A rank. For example, the card 2 accommodated in the card cassette 9 includes many cards 2 of different types and shapes. It is determined that the second probability is lower than the A rank, and is ranked as the B rank.

  As described above, when at least one of the peak intervals ti is out of the first reference range and the peak interval ti out of the first reference range is equal to or less than the first reference value RV1, at least one of the bottom intervals Ti is When the bottom interval Ti deviating from the second reference range and deviating from the second reference range is equal to or less than the second reference value RV2, and at least one of the cases where the average interval Wa is deviating from the third reference range The number of peaks exceeding the threshold value th1 of the sensor signal SG is calculated as the number of cards 2 accommodated in the card cassette 9, and ranked as B rank. For example, when the signal level of the sensor signal SG varies as shown in FIG. 7, the control unit 25 determines the number of peaks exceeding the threshold th1 of the sensor signal SG as the number of cards 2 accommodated in the card cassette 9. Calculate and rank with B rank.

  In step S21, when the peak interval ti outside the first reference range exceeds the first reference value RV1, and the bottom interval Ti outside the second reference range exceeds the second reference value RV2. In at least any one of the cases, the control unit 25 determines whether or not the peak interval ti exceeds the first reference value RV1 (step S23).

  In step S23, when the peak interval ti is equal to or less than the first reference value RV1 and the bottom interval Ti that is out of the second reference range exceeds the second reference value RV2, the control unit 25 sets the second reference value RV1. A correction value calculated based on the bottom interval Ti exceeding the value RV2 is calculated (step S24). Specifically, an integer closest to a value obtained by subtracting 1 from a value obtained by dividing the bottom interval Ti exceeding the second reference value RV2 by the reference value RV is calculated as a correction value. For example, in the example shown in FIG. 8A, the bottom interval T6 exceeds the second reference value RV2, and the integer closest to the value obtained by subtracting 1 from the value obtained by dividing the bottom interval T6 by the reference value RV is 1. Therefore, the correction value is 1.

  Further, the control unit 25 calculates the number obtained by adding the correction value to the number of peaks exceeding the threshold th1 of the sensor signal SG as the number of cards 2 accommodated in the card cassette 9, and ranks it as the C rank ( Step S25). That is, in this case, the control unit 25 determines that the first probability is lower than the A rank because the calculated number of cards 2 includes a correction value, and for example, stores the card cassette 9 in the card cassette 9. It is determined that the cards 2 of different types and shapes are mixed in the stored cards 2 and the second probability is lower than the A rank, or, for example, the cards 2 stored in the card cassette 9 are It is accommodated in a slanted state, and it is determined that the third likelihood is lower than the A rank, and is ranked as the C rank.

  On the other hand, when the peak interval ti exceeds the first reference value RV1 in step S23, the control unit 25 determines that the bottom of the signal level of the sensor signal SG at the peak interval ti exceeding the first reference value RV1. It is determined whether or not the threshold value is th0 or less (step S26). For example, as shown in FIG. 8A, when the bottom of the signal level of the sensor signal SG at the peak interval t6 exceeding the first reference value RV1 exceeds the threshold th0, the process proceeds to step S24 and the control is performed. The unit 25 calculates a correction value calculated based on the peak interval ti exceeding the first reference value RV1. Specifically, an integer closest to a value obtained by subtracting 1 from a value obtained by dividing the peak interval ti exceeding the first reference value RV1 by the reference value RV is calculated as a correction value. For example, in the example shown in FIG. 8A, since the integer closest to the value obtained by subtracting 1 from the value obtained by dividing the peak interval t6 by the reference value RV is 1, the correction value is 1. When the correction value is calculated in step S24, the process proceeds to step S25.

  Further, for example, as shown in FIG. 8B, when the bottom of the signal level of the sensor signal SG at the peak interval t7 exceeding the first reference value RV1 is equal to or less than the threshold th0, the control unit 25 For example, it is determined that a gap is formed between the cards 2 accommodated in the card cassette 9, and the number of peaks exceeding the threshold th1 of the sensor signal SG is determined as the number of peaks of the cards 2 accommodated in the card cassette 9. It is calculated as the number of sheets and ranked C rank (step S27). That is, in this case, the control unit 25 determines that the first likelihood is lower than the A rank, and determines that the second likelihood and / or the third likelihood is lower than the A rank, and C Rank with rank.

  As described above, the control unit 25 determines that the peak interval ti is out of the first reference range and the peak interval ti out of the first reference range exceeds the first reference value RV1, and the bottom interval Ti is the second reference range. The C rank is ranked in at least any one of cases where the bottom interval Ti deviating from the range and deviating from the second reference range exceeds the second reference value RV2.

  Further, as described above, the control unit 25 is calculated based on the comparison result between the first reference range and the first reference value RV1 calculated based on the reference value RV and the peak interval ti and the reference value RV. Based on the comparison result between the second reference range and the second reference value RV2 and the bottom interval Ti (that is, the comparison result between the reference value RV and the peak interval ti, or the comparison result between the reference value RV and the bottom interval Ti). Based on the above, the number of cards 2 stored in the card cassette 9 is calculated, and the ranks A, B, and C are ranked.

  In step S14, when the number of peaks exceeding the threshold value th1 is one, the control unit 25 performs a time interval from when the signal level of the sensor signal SG exceeds the threshold value th0 until the threshold value th0 is reached. It is determined whether or not a certain total time interval W is equal to or smaller than a predetermined third reference value RV3 (step S29). In step S29, when the total time interval W is equal to or smaller than the third reference value RV3, the control unit 25 calculates the number of cards 2 stored in the card cassette 9 as one and determines the rank A. And rank A (step S30). For example, when the signal level of the sensor signal SG fluctuates as shown in FIG. 6B, the control unit 25 calculates the number of cards 2 accommodated in the card cassette 9 as one and ranks A. Rank.

  On the other hand, when the total time interval W exceeds the third reference value RV3 in step S29, the control unit 25 calculates a value obtained by dividing the total time interval W by the reference value RV (step S31). The value is calculated as the number of cards 2 accommodated in the card cassette 9 and ranked as D rank (step S32). That is, in this case, since the calculated number of cards 2 is a completely estimated value based on the total time interval W and the reference value RV, the controller 25 determines that the first probability is lower than the C rank. At the same time, it is determined that the second likelihood and / or the third likelihood is also lower than the C rank, and is ranked as the D rank.

  For example, as shown in FIG. 9B, the light reflectance of the card 2 is low, the peak and bottom of the signal level of the sensor signal SG are not clear, and the signal level of the sensor signal SG exceeds the threshold th1. In step S14, it is determined that the number of peaks exceeding the threshold th1 is one, and in step S29, the total time interval W is determined to exceed the third reference value RV3. The Therefore, when the signal level of the sensor signal SG fluctuates as shown in FIG. 9B, the control unit 25 divides the value obtained by dividing the total time interval W by the reference value RV into the card accommodated in the card cassette 9. It is calculated as a number of 2 and ranked as D rank.

  If all the signal level peaks of the sensor signal SG are equal to or less than the threshold th1 in step S13, the control unit 25 calculates a value obtained by dividing the total time interval W by the reference value RV (step S33). This value is calculated as the number of cards 2 accommodated in the card cassette 9 and ranked as D rank (step S34). That is, in this case, since the calculated number of cards 2 is a completely estimated value based on the total time interval W and the reference value RV, the controller 25 determines that the first probability is lower than the C rank. At the same time, it is determined that the second likelihood and / or the third likelihood is also lower than the C rank, and is ranked as the D rank. For example, when the signal level of the sensor signal SG fluctuates as shown in FIG. 9A, the control unit 25 obtains the card accommodated in the card cassette 9 by dividing the total time interval W by the reference value RV. It is calculated as a number of 2 and ranked as D rank.

  In step S11, if the signal level of the sensor signal SG does not exceed the threshold th0, the control unit 25 calculates the number of cards 2 stored in the card cassette 9 as 0 and determines that the rank is A. And rank A (step S36). For example, as shown in FIG. 6C, when the signal level of the sensor signal SG does not fluctuate, the control unit 25 calculates the number of cards 2 accommodated in the card cassette 9 as 0 and rank A Rank.

  In this embodiment, the threshold th1 is a first threshold, and the threshold th2 is a second threshold. In addition, the threshold th0 in this embodiment is a third threshold and a fourth threshold. In this embodiment, the threshold value th1 that is the first threshold value and the threshold value th2 that is the second threshold value are different from each other. However, the first threshold value and the second threshold value may be the same value. In the present embodiment, the third threshold value and the fourth threshold value are the same value, but the third threshold value and the fourth threshold value may be different values.

(Main effects of this form)
As described above, in the present embodiment, the control unit 25 calculates the number of cards 2 accommodated in the card cassette 9 based on the sensor signal SG, and the first probability, the second probability, and the third. Ranking is performed by classifying into four ranks of A rank, B rank, C rank, and D rank, which use the three probabilities of probability and the criterion of rank determination. In addition, the control unit 25 transmits the calculated number information of the cards 2 and rank information that is rank information of the ranks to the upper control unit 30.

  Therefore, in this embodiment, based on the rank information transmitted to the card issuing device 3, it is determined on the card issuing device 3 side whether or not the card 2 accommodated in the card cassette 9 really needs to be confirmed. It becomes possible. For example, when rank information of C rank and D rank is transmitted, the card 2 accommodated in the card cassette 9 is confirmed, but when rank information of B rank is transmitted, it is stored in the card cassette 9. The card issuing device 3 can make a determination not to check the stored card 2. Further, in this embodiment, the calculated card number information of the card 2 is transmitted to the upper control unit 30 together with the rank information regardless of the rank of rank A to rank D. When the card issuing device 3 determines that the stored card 2 is not confirmed, the processing of the card issuing device 3 can be executed as it is. Therefore, in this embodiment, it becomes possible to improve the usability of the card issuing device 3 on which the card counting device 1 is mounted.

  In the present embodiment, the control unit 25 has all the peak intervals ti within the first reference range, all the bottom intervals Ti within the second reference range, and the average interval Wa within the third reference range. In this case, it is ranked as A rank. That is, in this embodiment, the control unit 25 ranks the A rank when all of the peak intervals ti, all of the bottom intervals Ti, and the average interval Wa are normal. Therefore, in this embodiment, the first likelihood, the second likelihood, and the third likelihood when the rank A rank information is transmitted to the card issuing device 3 are further increased. Therefore, when rank information of rank A is transmitted, the subsequent processing of the card issuing device 3 can be executed with confidence without checking the card 2 accommodated in the card cassette 9.

  In this embodiment, the control unit 25 determines that the peak interval ti that is out of the first reference range is equal to or less than the first reference value RV1, and the bottom interval Ti that is out of the second reference range is equal to or less than the second reference value RV2. In this case, the number of peaks exceeding the threshold th1 of the sensor signal SG is calculated as the number of cards 2 accommodated in the card cassette 9, and is ranked as B rank. That is, in this embodiment, when ranked as B rank, even if the peak interval ti is out of the first reference range, it is not more than the first reference value RV1, and the bottom interval Ti is not more than the second reference range. Even if it is off, it is equal to or less than the second reference value RV2, so that the first likelihood of the A rank and the first likelihood of the B rank can be set to the same degree of certainty.

  In the present embodiment, the control unit 25 determines the second reference value when the peak interval ti is equal to or less than the first reference value RV1 and the bottom interval Ti that is out of the second reference range exceeds the second reference value RV2. A correction value calculated based on the bottom interval Ti exceeding RV2 is calculated, and the number obtained by adding the correction value to the number of peaks exceeding the threshold value th1 of the sensor signal SG is used as the number of cards 2 accommodated in the card cassette 9. While calculating, it ranks as C rank. Further, the controller 25 is a case where the peak interval ti exceeds the first reference value RV1, and the bottom of the signal level of the sensor signal SG at the peak interval ti exceeding the first reference value RV1 sets the threshold th0. If it exceeds, the correction value calculated based on the peak interval ti exceeding the first reference value RV1 is calculated, and the number obtained by adding the correction value to the number of peaks exceeding the threshold th1 of the sensor signal SG is obtained as a card cassette. 9 is calculated as the number of cards 2 accommodated in 9 and ranked as C rank. Further, the control unit 25 counts the number of peaks exceeding the threshold value th1 of the sensor signal SG when the bottom of the signal level of the sensor signal SG at the peak interval ti exceeding the first reference value RV1 is equal to or less than the threshold value th0. Is calculated as the number of cards 2 accommodated in the card cassette 9 and is ranked as C rank. Therefore, in this embodiment, it is possible to increase the first likelihood (the likelihood of the number of cards 2) when ranked in the C rank.

  In the present embodiment, the control unit 25 uses the card cassette when the signal level of the sensor signal SG has one peak that exceeds the threshold th1 and the total time interval W is equal to or less than the third reference value RV3. 9 calculates the number of cards 2 accommodated as one and determines it as A rank and ranks it as A rank. In the present embodiment, the control unit 25 calculates the number of cards 2 stored in the card cassette 9 as 0 and determines the rank A when the signal level of the sensor signal SG does not exceed the threshold th0. And rank A. Therefore, in this embodiment, even when the number of cards 2 accommodated in the card cassette 9 is 1 or 0, the number of cards 2 accommodated in the card cassette 9 can be appropriately calculated. It becomes possible to perform an appropriate ranking.
