The identification unit 60 includes an identification storage unit 65 and an identification control unit 66 in addition to the sensors described above.

The identification storage unit 65 stores templates such as image information, magnetic information, thickness information of bills, and the like, which serve as references for identifying the denomination, authenticity, fitness and the like of bills. Further, the identification storage unit 65 temporarily stores the banknote image information acquired by the optical line sensor 62, the banknote thickness information acquired by the thickness detection sensor 63, and the banknote magnetic information acquired by the magnetic line sensor 64. Remember.

The identification control unit 66 compares the information acquired by the optical line sensor 62, the thickness detection sensor 63, and the magnetic line sensor 64 with each of the identification reference templates stored in the identification storage unit 65, thereby identifying bills. I do.

The identification control section 66 has a first core 651 , a second core 652 and a third core 653 . That is, the identification control unit 66 is configured including a multi-core CPU. Here, a multi-core CPU is a processing device in which a plurality of processor cores are mounted in one CPU package. The identification control unit 66 can execute identification processing in parallel in each core.

The identification control unit 66 includes a first cache 651 a connected to the first core 651 , a second cache 652 a connected to the second core 652 , and a third cache 652 a connected to the third core 653 . A cache 653a is provided.

The first cache 651a, the second cache 652a, and the third cache 653a are storage devices that temporarily store information read from the identification storage unit 65, respectively.

The first core 651 uses the information temporarily stored in the first cache 651a to identify bills. The second core 652 also uses the information temporarily stored in the second cache 652a to identify bills. Also, the third core 653 uses the information temporarily stored in the third cache 653a to identify bills.

Also, the first core 651, the second core 652 and the third core 653 are connected to each other via a bus (not shown), and the first core 651, the second core 652 and the third core 653 communicate with each other via the bus.

Further, the third core 653 identifies the further banknote based on the information of the further banknote acquired by each sensor. That is, in the identification control unit 66, each core that executes bill identification processing is assigned to each bill. Note that the first core 651 , the second core 652 and the third core 653 are repeatedly used to identify banknotes being transported by the transport unit 50 . Also, another banknote identified by the second core 652 is a banknote that is conveyed after the one banknote identified by the first core 651, and yet another banknote identified by the third core 653. is a note that is conveyed after another note identified by the second core 652 .

Here, a description will be given of how bill identification processing is performed in the identification control unit 66 when the identification control unit 66 is configured by a single-core CPU having one core.

FIG. 4 is a timing chart of identification processing executed when the identification control unit 66 is configured with a single-core CPU. In FIG. 4 , (1), (2), (3), (4), (5), and (6) show the transport state of banknotes on the transport unit 50 in chronological order. In addition, in FIG. 4, illustration of the thickness detection sensor 63 and the magnetic line sensor 64 of the identification unit 60 is omitted for simplification of explanation. The transport unit 50 transports each bill at a constant speed. Therefore, the movement distance of the banknote is proportional to the time required for movement. Therefore, in FIG. 4, the horizontal length represents the length of time. That is, in FIG. 4, the horizontal axis is the axis indicating the position in the bill conveying direction and the time axis.

Further, t1 indicates the timing at which the recognition control unit 66 receives a recognition result request signal from the control unit 80 requesting the banknote recognition result. Upon receiving the identification result request signal, the identification control unit 66 transmits the bill identification result to the control unit 80 . Further, t1 indicates the timing at which the identification control unit 66 should complete the bill identification processing. Timing t<b>1 at which bill identification processing should be completed is determined based on the timing at which bills reach the bifurcation claw 51 . That is, in order for the control unit 80 to sort the banknotes into the reject unit 20 or the storage unit 70, before the banknotes reach the bifurcation claw 51 provided on the transport unit 50, the recognition control unit 66 outputs the recognition results of the banknotes. need to receive. Therefore, the timing t<b>1 at which bill identification processing should be completed is set before the timing at which the bill reaches the bifurcation claw 51 .

The arrow A1 indicates that the identification control unit 66 is performing identification processing for the first banknote S1 that first passed through the optical line sensor 62, and the arrow A2 indicates that the identification control unit 66 It shows that the identification processing of the second banknote S2 that passed 62 second is being performed.

(1) shows the transport state of the banknotes on the transport unit 50 at the timing when the first banknote S1 reaches the optical line sensor 62 after passing the photosensor 61 .

(2) shows the transport state of the banknotes on the transport unit 50 at the timing when the first banknote S1 passes the optical line sensor 62 and the recognition control unit 66 starts the recognition processing of the first banknote S1. . Here, T1 is the time used by the identification control unit 66 to perform the identification processing of the first bill S1. It should be noted that S2 is the second banknote identified next to the first banknote S1.

(3) shows the transport state of the banknotes on the transport unit 50 at the timing when the second banknote S2 reaches the optical line sensor 62 .

(4) shows the transport state of the banknotes on the transport unit 50 at the timing when the second banknote S2 passes the optical line sensor 62 . At this time, the time T1 has not passed since the identification processing of the first banknote S1 was started, and the identification processing of the first banknote S1 has not yet been completed in the identification control unit 66 . Therefore, the identification control section 66 cannot start the identification processing of the second bill S2. It should be noted that S3 is the third banknote identified next to the second banknote S2.

(5) shows the transport state of the banknotes on the transport unit 50 when the time T1 has passed since the first banknote S1 passed the optical line sensor 62 . At this timing, the identification processing of the first banknote S1 is completed, and the identification processing of the second banknote S2 is started.

After time T2 has passed from the state shown in (5), the second banknote S2 reaches timing t1 at which the banknote recognition processing should be completed. However, time T2 is shorter than time T1. That is, the identification control unit 66 cannot complete the identification processing of the second banknote S2 before the timing t1 at which the identification processing of the second banknote S2 should be completed.

(6) shows the transport state of the banknotes on the transport unit 50 when the second banknote S2 reaches the timing t1 at which the banknote identification process should be completed. Time T3 is the difference between time T1 and time T2. After the time T3 has elapsed from the state shown in (6), the identification processing of the second bill S2 is completed. In this case, there is a possibility that the second banknotes S2 cannot be properly sorted by the bifurcation claw 51 . Note that S4 is the fourth banknote S4 identified next to the third banknote S3.

As indicated by arrows A1 and A2 in FIG. 4, when the identification control unit 66 is a single-core CPU, the identification control unit 66 performs the second The identification process for banknote S2 cannot be started. That is, while the identification processing of the first banknote S1 is being performed, although the information of the second banknote S2 is acquired by each sensor of the identification unit 60, the identification control unit 66 performs the second The identification process for banknote S2 cannot be started.

Therefore, as shown in FIG. 4, the start timing of the identification processing of the second banknote S2 is delayed, and the identification processing of the second banknote S2 may not be completed by the timing t1 when the identification processing should be completed. .

The third core 653 reads the image information, the magnetic information and the thickness information of the third banknote S3 from the identification storage unit 65 when the information of the third banknote S3 is acquired by each sensor of the recognition unit 60 . Accordingly, the image information, magnetic information and thickness information of the third bill S3 are also stored in the third cache 653a.

Further, the third core 653 reads out the denomination of the third banknote S3, an image serving as a reference for discriminating authenticity and fitness, a magnetic template, and a banknote thickness template. As a result, the denomination of the third banknote S3, the image serving as the reference for identifying authenticity and fitness, and the magnetic and banknote thickness templates are also stored in the third cache 653a. The third core 653 identifies the denomination, authenticity, and fitness of the third bill S3 based on the information stored in the third cache 653a and the information read from the identification storage unit 65 as necessary. I do.

The third core 653 performs these processes regardless of whether the first core 651 or the second core 652 has performed the identification process for the first banknote S1 or the second banknote S2. .

The third core 653 stores the identification result of the third banknote S3 in the identification storage unit 65 when the identification of the denomination, authenticity and fitness of the third banknote S3 is completed.

Upon receiving the identification result request signal for the third banknote S3 from the control unit 80 , the identification unit 60 transmits the identification result of the third banknote S3 stored in the identification storage unit 65 to the control unit 80 .

As described above, in the money handling apparatus 100 according to the present embodiment, each core of the identification storage unit 65 configured by a multi-core CPU identifies all of the denomination, authenticity, and fitness of one banknote. do. Therefore, the identification control unit 66 does not need to transmit and receive bill identification results between the cores. Therefore, the processing load and processing time for communication processing in the first core 651, the second core 652 and the third core 653 can be suppressed. As a result, it is possible to shorten the processing time for bill identification processing in the identification control unit 66 .

Information stored in the cache connected to each core is rewritten each time the denomination, authenticity, and fitness are identified in the first core 651, the second core 652, and the third core 653. does not need to be Therefore, the first core 651 , the second core 652 and the third core 653 can reduce the number of times the process of reading information from the identification storage unit 65 is executed. As a result, the processing load on the first core 651, the second core 652, and the third core 653 can be reduced, and the processing time for bill identification processing can be shortened.

Further, when an error occurs in any one of the core group including the first core 651, the second core 652 and the third core 653, the identification control unit 66 causes the other cores included in the core group to can be used to continue the identification process. Therefore, even if an error occurs in any of the cores of the identification control unit 66, it is possible to avoid stopping the bill identification processing. In other words, the core in which the error occurred cannot complete the identification processing of the banknote, so the banknote identified by the core in which the error occurred is conveyed to the reject section 20 . However, since the remaining cores other than the core in which the error occurred complete the identification processing of the banknotes and can continue to perform the identification processing of subsequent banknotes being transported by the transport unit 50, the recognition control unit 66 Even if an error occurs in any of the cores, the number of banknotes transported to the reject section 20 can be reduced to one. At this time, among the remaining cores included in the core group, one core identifies one bill, another core identifies another bill conveyed after the one bill, and one core identifies , identifies further banknotes that are transported after another banknote.

Next, the flow of identification processing executed by the money handling apparatus 100 according to the present embodiment will be described with reference to FIG. FIG. 6 is a timing chart showing identification processing executed by the money handling apparatus 100. As shown in FIG. Note that the horizontal axis in FIG. 6 is the axis indicating the position in the bill conveying direction and the time axis, as in FIG. 4 .

(1) shows the transport state of the banknotes on the transport unit 50 at the timing when the first banknote S1 reaches the optical line sensor 62 after passing the photosensor 61 .

(2) shows the transport state of the banknotes on the transport unit 50 at the timing when the first banknote S1 passes the optical line sensor 62 and the first core 651 starts identification processing of the first banknote S1. there is Here, T1 is the time used by the first core 651 to perform the identification process of the first bill S1.

(3) shows the transport state of the banknotes on the transport unit 50 at the timing when the second banknote S2 reaches the optical line sensor 62 .

(4) shows the transport state of the banknote on the transport unit 50 at the timing when the second banknote S2 passes the optical line sensor 62 and the second core 652 starts identification processing of the second banknote S2. there is Here, T1 is the time used by the second core 652 to perform the identification process for the second bill S2. At this time, the identification processing of the first bill S1 in the first core 651 has not yet been completed. However, the second core 652 initiates the identification process for the second note S2.

(5) shows the transport state of the banknotes on the transport unit 50 when the time T1 has passed since the first banknote S1 passed the optical line sensor 62 . At this timing, the identification processing of the first bill S1 in the first core 651 is completed.

(6) shows the transport state of the banknotes on the transport unit 50 when the time T1 has passed since the second banknote S2 passed the optical line sensor 62 . At this timing, the identification processing of the second bill S2 in the second core 652 is completed.

That is, in the money handling apparatus 100 according to the present embodiment, as indicated by arrows A1 and A2 in FIG. , the second core 652 starts the identification process of the second bill S2. As a result, T1 time elapses from when the second core 652 starts identification processing of the second banknote S2 to timing t1 at which the identification processing of the banknote should be completed. That is, the second core 652 can complete the identification processing of the second banknote S2 before the timing t1 at which the identification processing of the banknote should be completed. As a result, the second banknotes S2 are properly sorted by the bifurcation claw 51 without fail.

In the above-described embodiment, the identification control unit 66 has three cores, and uses these cores to execute bill identification processing. However, the number of cores that the identification control unit 66 has is not limited to three, and may be two or four or more.

Further, in the embodiment described above, the identification control section 66 is configured by a multi-core CPU. However, the configuration of the identification control unit 66 is not limited to this, and may include a plurality of single-core CPUs. In this case as well, each CPU executes identification processing for all of the denomination, authenticity, and fitness of one banknote, as in the above-described embodiment. This makes it possible to obtain the same effect as the embodiment described above.
