[Technical Field]

[0001] The present invention relates to a currency handling device and a method for controlling the currency handling device. [Background technology]

[0002] Patent document 1 describes a currency processing device that stores the serial numbers of currency in association with date and time information as transaction log data, and analyzes the cause from the log data when the quantities do not match during the inspection process.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-109839 Summary of the Invention [Problem to be solved by the invention]

[0004] During maintenance of a currency handling device, workers refer to the work log data to understand the state of the currency handling device. For example, in a currency handling device, the occurrence and resolution of events such as currency jams are detected by sensors installed in the currency handling device. However, it is difficult for sensors to detect the details of maintenance work performed by workers to address abnormalities. Therefore, the log data generated based on the sensors alone may not provide sufficient information.

[0005] For example, if a foreign object or a coin jam is detected in a currency processing device, an operator must clean the jammed area and the sensor. At this time, the type of maintenance work performed by the operator, such as information on the areas that have been cleaned, is not stored as log data. Therefore, even if an operator forgets to clean, it may not be possible to check the log data later. Currency processing devices have a complex configuration, with numerous areas requiring cleaning, a wide variety of cleaning conditions, and many small areas being cleaned. Therefore, it can be difficult for operators to manually keep accurate records of their work. An object of the present invention is to provide a currency processing device and a control method for the currency processing device that can easily record logs of work performed by workers. [Means for solving the problem]

[0006] According to one aspect of the present invention, a currency processing device is provided with a voice input unit that accepts voice input, and a memory unit that stores device log information representing the operating status of the currency processing device and voice log information representing the work status of a worker that is voice input by the worker via the voice input unit, in association with time. [Effects of the Invention]

[0007] According to the above aspect, the currency processing device can easily record a log of work performed by workers. [Brief explanation of the drawings]

[0009] First Embodiment <Configuration of currency processing device>

[0010] Fig. 1 is a perspective view of a currency handling apparatus 1 according to the first embodiment. Fig. 2 is a block diagram showing the configuration of the currency handling apparatus 1 according to the first embodiment. The currency handling device 1 has a banknote handling unit 2, a coin handling unit 3, and a terminal 10. The banknote handling unit 2 stores and manages banknotes. The coin handling unit 3 stores and manages coins. The terminal 10 manages the entire currency handling device 1, including the banknote handling unit 2 and the coin handling unit 3. In the example shown in Figure 2, the currency handling device 1 has two terminals 10. Of the two terminals 10, the terminal 10 operated by the user functions as the main device. The terminal of the main device outputs a signal to the other terminal 10, and the terminal 10 that receives the signal functions as the sub-device. Note that in other embodiments, the currency handling device 1 may have only one terminal 10.

[0011] The banknote processing unit 2, in accordance with instructions from the terminal 10, deposits and dispenses banknotes, identifies and counts the deposited and dispensed banknotes, and controls the transport of the banknotes. The coin processing unit 3, in accordance with instructions from the terminal 10, deposits and dispenses coins, identifies and counts the deposited and dispensed coins, and controls the transport of coins. Sensors (not shown) for detecting processing abnormalities are provided in the banknote processing unit 2 and the coin processing unit 3. The sensors are provided in the transport path for transporting banknotes or coins, the cassettes for storing banknotes or coins, etc.

[0012] The coin processing unit 3 includes a transport unit 30 for transporting coins. The transport unit 30 includes a dispensing transport path 31 that transports coins from the cassette to the outside, a return transport path 32 that transports coins from the outside to the cassette, a front door 33 that is flush with the housing when the transport unit 30 is stored in the housing, and a foreign object sensor 34 that detects blockages in the dispensing transport path 31 and the return transport path 32. When cleaning or maintenance is performed inside the transport unit 30, the transport unit 30 can be pulled out from the front of the housing. Figure 1 shows the transport unit 30 stored in the housing, with the interior of the housing partially indicated by dotted lines.

[0013] The terminal 10 includes a display operation unit 11, a voice input unit 12, a communication unit 13, and a computer 14. The display operation unit 11 accepts operations when the worker P touches the screen, and displays the status of the currency handling device 1. The display operation unit 11 is configured, for example, by a touch panel. The display operation unit 11 is an example of a display unit and an input unit. Note that the display operation unit 11 does not necessarily have to have the display unit and input unit integrated together, as in a touch panel, and may be configured with an input unit such as a mouse and keyboard, and a display unit such as a display. The voice input unit 12 receives voice input from the worker P. The voice input unit 12 is configured by, for example, a microphone. The communication unit 13 is connected to other devices via a network so as to be able to communicate with them, and can output information generated by the terminal 10 to the other devices.

[0014] The computer 14 executes processing in accordance with the operation of the display operation unit 11, and displays the results on the display operation unit 11. The computer 14 includes a processor 141, a storage 142, a main memory 143, and an interface 144.

[0015] Examples of storage 142 include a magnetic disk, a magneto-optical disk, an optical disk, and a semiconductor memory. Storage 142 stores a maintenance support program D1, authentication information D2, and guidance information D3. Maintenance support program D1 records log information indicating the operating status of currency handling apparatus 1 and the work status of operator P, and is a program for viewing maintenance work guidance and the recorded log information. Authentication information D2 is information that associates operator P's ID, name, affiliation, and voice features of said operator P. Examples of voice features include Mel frequency cepstrum coefficients. Authentication information D2 is recorded for each operator P. Guidance information D3 is data representing guidance for each step of maintenance work for currency handling apparatus 1, which is performed in multiple steps. Guidance information D3 is recorded for each maintenance work content.

[0016] In addition, in the storage 142, device log information D4 and voice log information D5 are recorded in association with the operation of the currency handling device 1. The device log information D4 is information that chronologically records the history of the state of the currency handling device 1. The device log information D4 is data that records the operating status of the currency handling device 1, generated based on input from the display operation unit 11 of the currency handling device 1 and signals from various sensors (not shown). The voice log information D5 is information that records the history of work content in chronological order, generated from the voice spoken by the worker P while he / she is working. The voice log information D5 is mainly data that records the work status of the worker P that is not stored as the device log information D4. Note that the terminal 10 may also store information that is stored as the device log information D4, such as "The device has started operating normally," as the voice log information D5.

[0017] The processor 141 reads the maintenance support program D1 from the storage 142, loads it into the main memory 143, and executes predetermined processing in accordance with the maintenance support program D1. Examples of the processor 141 include a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and a microprocessor. The processor 141 is connected to the display operation unit 11, the voice input unit 12, the communication unit 13, the banknote processing unit 2, and the coin processing unit 3 via the interface 144.

[0018] The processor 141 executes the maintenance support program D1, thereby providing a log recording unit 401, a voice authentication unit 402, a voice recognition unit 403, a guidance presentation unit 404, and a log presentation unit 405.

[0019] The log recording unit 401 records device log information D4 generated in conjunction with the operation of the currency handling device 1 in association with the time in the storage 142. The log recording unit 401 records voice log information D5 generated from the voice of the worker P input to the voice input unit 12 in association with the time in the storage 142.

[0020] The voice authentication unit 402 performs authentication processing for the worker P based on the voice of the worker P input via the voice input unit 12 and the voice features included in the authentication information D2 recorded in the storage 142. The voice recognition unit 403 performs a voice recognition process to convert the voice of the worker P input via the voice input unit 12 into text data.

[0021] The guidance presenting unit 404 displays the guidance information D3 recorded in the storage 142 on the display operation unit 11. The guidance presenting unit 404 updates the display content of the guidance information D3 based on the voice recognized by the voice recognition unit 403. For example, when the voice recognition unit 403 recognizes a keyword such as "complete" or "next," the guidance presenting unit 404 advances the step of the guidance displayed on the display operation unit 11 by one.

[0022] The log presenting unit 405 outputs the device log information D4 and the voice log information D5 recorded in the storage 142 in accordance with a presentation instruction input from the worker P via the display operation unit 11 or a presentation instruction input from another device via the communication unit 13. When a presentation instruction is input via the display operation unit 11, the log presenting unit 405 outputs the device log information D4 and the voice log information D5 to the display operation unit 11. When a presentation instruction is input via the communication unit 13, the log presenting unit 405 outputs the device log information D4 and the voice log information D5 to the other device via the communication unit 13.

[0023] <<Example of maintenance work>> A series of operations for maintenance work on the currency handling device 1 according to the first embodiment will now be described. Fig. 3 is a flowchart showing an example of maintenance work operations according to the first embodiment. The example shown in Fig. 3 is an operation in which, when an error occurs in which a coin is jammed in the dispensing conveying path 31 of the currency handling device 1, an operator P pulls out the conveying unit 30, removes the jammed coin from the dispensing conveying path 31, and cleans the dispensing conveying path 31 and the foreign object sensor 34.

[0024] When the foreign object sensor 34 detects that a coin has jammed in the dispensing conveyance path 31 or the return conveyance path 32, a warning screen G0 notifying the user of the coin jam is displayed on the display / operation unit 11 of the terminal 10 (step S101). FIG. 4 is a diagram showing an example of the warning screen G0 according to the first embodiment. As shown in FIG. 4, the warning screen G0 includes a message notifying the user of the error, such as "Coins are jammed in the conveyance path," and a guidance message, such as "Please verbally input your affiliation, name, and the details of the process." The display of the guidance shown in FIG. 4 prompts the user P to input the affiliation, name, and details of the process to be performed by voice. When the user P verbally utters his / her affiliation, name, and details of the process, the voiced sound is input to the voice input unit 12 (step S102). For example, the user P may utter, "Taro Tanaka, Maintenance Section 1, will clear the jammed coins in the conveyance path," as shown in FIG. 4.

[0025] The terminal 10 displays a first guidance screen G1 on the display operation unit 11 in response to the voice input from the operator P via the voice input unit 12 (step S103). FIG. 5 is a diagram showing an example of the first guidance screen G1 according to the first embodiment. The first guidance screen G1 shown in FIG. 5 is a guidance screen showing a foreign object removal method. On the first guidance screen G1, drawings or photographs and text showing the operation procedure are displayed side by side. The display of the first guidance screen G1 is stored as device log information D4.

[0026] An example of the sentences indicating the operating procedures included in the first guidance screen G1 is as follows: 1. Pull out the transport path unit. 2. If there are any foreign objects on the dispensing or returning transport paths, remove them. 3. Open the front door of the transport unit. 4. If there is any foreign object in the foreign object sensor, remove it. 5. Once you have removed the foreign object, say "Foreign object removed."

[0027] Following the first guidance screen G1, the worker P pulls out the transport unit 30 (step S104) and removes the jammed coins from the dispensing transport path 31 (step S105). After removing the jammed coins from the dispensing transport path 31 of the transport unit 30, the worker P utters "Foreign object removal completed" (step S106). The terminal 10 converts the input voice into text data, associates it with the time as voice log information D5, and records it in the storage 142. This allows the terminal 10 to store the work status in which the worker P removed the foreign object as voice log information D5 in the storage 142. Note that such work status cannot be detected by sensors such as the foreign object sensor 34, and therefore cannot be recorded as the device log information D4.

[0028] In addition to uttering "Foreign object removal completed" as specified on the first guidance screen G1, the worker P may also vocalize other steps. In this case, the terminal 10 records the voices uttered in each step as voice log information D5 in the storage 142. For example, the worker P may vocalize the work status, such as "The transport unit was pulled out," "No foreign object was found in the dispensing transport path," "A 500 yen coin was jammed in the return transport path, so it was removed," "The front door of the transport path unit was opened," or "No foreign object was found around the foreign object sensor." This allows the terminal 10 to record details of the work status that cannot be detected by various sensors as voice log information D5 in the storage 142.

[0029] In response to the operator P's voice input of "foreign object removal completed," the terminal 10 causes the display operation unit 11 to display a second guidance screen G2 showing guidance related to the next step after the first guidance screen G1. FIG. 6 is a diagram showing an example of the second guidance screen G2 according to the first embodiment. As shown in FIG. 6, the second guidance screen G2 displays a message such as "Please clean the transport path" alongside a diagram or photo and text showing the operation procedure. The display of the second guidance screen G2 is stored as apparatus log information D4.

[0030] An example of the sentences indicating the operating procedures included in the second guidance screen G2 is as follows: 1. Clean the withdrawal and return transport paths. 2. When cleaning is complete, say "Conveyor path cleaning completed."

[0031] The worker P follows the second guidance screen G2 to clean the dispensing conveyance path 31 and the return-in conveyance path 32 (step S108). When the worker P has finished cleaning the dispensing conveyance path 31 and the return-in conveyance path 32, the worker P inputs by voice, "Conveyance path cleaning completed" (S109). This allows the work status after the cleaning of the dispensing conveyance path 31 and the return-in conveyance path 32 has been completed to be recorded in the storage 142 as voice log information D5.

[0032] In addition to uttering "Cleaning of the conveyance path completed" as specified on the second guidance screen G2, the worker P may also vocalize other steps. In this case, the terminal 10 records the voices uttered in each step as voice log information D5 in the storage 142. For example, the worker P may vocalize the work status, such as "Cleaning of the dispensing conveyance path completed," "No particularly noticeable dirt was found," "Cleaning of the return conveyance path completed," "Dirt was found on the belt of the conveyance path, but it was cleaned and is now clean," or "No cracks or the like were found on the belt." This allows the terminal 10 to record details of the work status that cannot be detected by various sensors as voice log information D5 in the storage 142.

[0033] In response to the operator P's voice input of "conveyor path cleaning completed," the terminal 10 causes the display operation unit 11 to display a third guidance screen G3 showing guidance related to the next step after the second guidance screen G2. FIG. 7 is a diagram showing an example of the third guidance screen G3 according to the first embodiment. As shown in FIG. 7, the third guidance screen G3 displays a message such as "Please clean the foreign object sensor" alongside a diagram or photo and text showing the operation procedure. The display of the third guidance screen G3 is stored as apparatus log information D4.

[0034] An example of the sentences indicating the operating procedures included in the third guidance screen G3 is as follows: 1. Clean the foreign object sensor. 2. Once cleaning is complete, say "Foreign object sensor cleaning completed." 3. Push the transport unit in.

[0035] The worker follows the third guidance screen G3 to clean the foreign object sensor 34 (step S111). When cleaning of the foreign object sensor 34 is complete, the worker inputs "Foreign object sensor cleaning completed" by voice (step S112). This enables the terminal 10 to store the work status after cleaning of the foreign object sensor 34 is completed in the storage 142 as voice log information D5.

[0036] In addition to uttering "Foreign object sensor cleaning completed" as specified on the third guidance screen G3, the worker P may also vocalize other steps. In this case, the terminal 10 records the voices uttered in each step as voice log information D5 in the storage 142. For example, the worker P may vocalize the work status and reference information such as "Cleaning of the foreign object sensor is completed. No particularly noticeable dirt was found," "Cleaning of the foreign object sensor is completed," or "The dirt on the surface of the foreign object sensor is not sufficiently cleaned, so you may want to consider replacing it at the next maintenance." This allows the terminal 10 to record details of the work status that cannot be detected by various sensors and reference information for the next maintenance work as voice log information D5 in the storage 142.

[0037] When the operator P has completed the cleaning of the foreign object sensor and has made a voice input, he or she pushes the transport unit 30 into the housing of the currency processing device 1 (step S113). By pushing the transport unit 30 into the currency processing device 1, the terminal 10 can detect whether the foreign object sensor 34 is operating properly. The terminal 10 notifies the operator via the display operation unit 11 whether the foreign object sensor 34 is operating properly, and records this as device log information D4 in the storage 142. The terminal 10 then displays a screen on the display operation unit 11 notifying the operator that the maintenance work to remove the jam has been completed (step S114).

[0038] Terminal 10 Operation 8 is a flowchart showing the processing of the terminal 10 during maintenance work according to the first embodiment. The terminal 10 performs the processing shown in FIG. 8 to realize the maintenance work shown in FIG.

[0039] When the log recording unit 401 of the terminal 10 acquires measurement data indicating an error from a sensor such as the foreign object sensor 34, it generates device log information D4 indicating the occurrence of the error and records it in the storage 142 in association with the time (step S1). Next, the guidance presentation unit 404 causes the display operation unit 11 to display a warning screen G0 shown in FIG. 4 (step S2).

[0040] The voice input unit 12 waits for voice input from the worker P. At this time, the voice input unit 12 may accept voice input from multiple workers P. When the voice input unit 12 receives voice input, the voice recognition unit 403 converts the input voice into text data (step S3). The voice authentication unit 402 extracts features from the input voice data (step S4). The voice authentication unit 402 performs authentication processing for the worker P by comparing the text data of the name and affiliation included in the voice obtained in step S3 with the name and affiliation related to the authentication information D2 recorded in the storage 142, and by comparing the features of the voice obtained in step S4 with the features related to the authentication information D2 recorded in the storage 142 (step S5). If the authentication processing for the worker P fails (step S5: NO), the terminal 10 returns the processing to step S3 and waits for voice input. At this time, the guidance presentation unit 404 may display a message on the display operation unit 11 indicating that the authentication has failed.

[0041] If the authentication process for worker P is successful (step S5: YES), the log recording unit 401 records the combination of the text data obtained in step S3 and the ID of worker P identified as a result of the authentication as voice log information D5, associated with the time, in storage 142 (step S6).

[0042] Based on the content of the error obtained in step S1, the guidance presentation unit 404 reads out the corresponding guidance information D3 from the storage 142 and causes the display operation unit 11 to display a guidance screen showing the first step of the guidance information D3 (step S7).

[0043] The voice input unit 12 waits for voice input from the worker P. When voice is input to the voice input unit 12, the voice recognition unit 403 converts the input voice into text data (step S8). The log recording unit 401 records a combination of the text data obtained in step S8 and the ID of the worker P as voice log information D5 in the storage 142 in association with the time (step S9). The guidance presentation unit 404 compares the specific phrase for transitioning to the next step, which is set in the guidance information D3, with the text data obtained in step S8, and determines whether the specific phrase for transitioning to the next step has been uttered (step S10). Examples of the specific phrase for transitioning to the next step include "Foreign object removal completed" on the first guidance screen G1 shown in FIG. 5, "Conveyor path cleaning completed" on the second guidance screen G2 shown in FIG. 6, and "Foreign object sensor cleaning completed" on the third guidance screen G3 shown in FIG. 7. The specific phrase does not need to be different for each guidance screen and may be, for example, "Complete" or "Next." The guidance presentation unit 404 may determine whether the specific phrase has been uttered by, for example, determining whether the text data obtained in step S8 includes the specific phrase, or by determining whether the distance (e.g., Levenshtein distance) between the text data obtained in step S8 and the specific phrase is equal to or less than a predetermined value.

[0044] If the specific phrase for transitioning to the next step is not uttered (step S10: NO), the terminal 10 returns the process to step S8 and waits for voice input. If a specific phrase for transitioning to the next step is uttered (step S10: YES), the guidance presenter 404 determines whether or not the next step exists in the guidance information D3 (step S11). If the next step exists (step S11: YES), the guidance presenter 404 causes the display operation unit 11 to display a guidance screen indicating the next step (step S12). Then, the terminal 10 returns the process to step S8 and waits for voice input.

[0045] If there is no next step (step S11: NO), the guidance presentation unit 404 waits for the execution of a specific process for ending the maintenance work (step S13). An example of the specific process for ending the maintenance work is pushing the transport unit 30 in the third guidance screen G3 shown in FIG. 7. Alternatively, the specific process for ending the maintenance work may be uttering a specific message. When the specific process is executed, the sensor generates measurement data. The log recording unit 401 generates apparatus log information D4 based on the measurement data and records it in the storage 142 in association with the time (step S14). If the error has been resolved, the guidance presentation unit 404 displays a screen indicating the end of the maintenance work on the display operation unit 11 (step S15), and ends the process.

[0046] If the measurement data obtained in step S14 indicates the presence of an error, the terminal 10 returns the process to step S1 and makes the worker P perform the maintenance work again.

[0047] <<Log information output>> FIG. 9 is a diagram illustrating an example of output of log information according to the first embodiment. Measurement data obtained by various sensors of the currency processing device 1 is recorded as device log information D4. When displaying the device log information D4, the log presentation unit 405 rewrites the device log information D4 into text data and outputs it. Voice input via the voice input unit 12 is recorded as voice log information D5. The voice log information D5 is converted into text data by the voice recognition unit 403.

[0048] The log presenting unit 405 outputs log data in response to a request from another device. At this time, the log presenting unit 405 generates log data in which the device log information D4 and the voice log information D5 are arranged in chronological order according to time. As shown in Fig. 9, the log data includes the time, the content of the log information, the type of the log information, and the voice authentication result.

[0049] Furthermore, after completing the maintenance work, the worker P can input an instruction to create a work record to the display operation unit 11. When the display operation unit 11 accepts the input of the instruction to create a work record, the log presentation unit 405 generates and outputs work record data based on the log information recorded in the storage 142. Fig. 10 is a diagram showing an example of work record data according to the first embodiment. The work record data includes the work date, work time, worker, device number, work content, and response content details, as shown in Fig. 10. The response content details are data in which device log information D4 and voice log information D5 are arranged in chronological order according to time, similar to the log data shown in Fig. 9.

[0050] Actions and Effects As described above, the currency handling device 1 according to the first embodiment includes a voice input unit 12 that accepts voice input, and a terminal 10 that stores, in storage 142, device log information D4 that indicates the operating status of the currency handling device 1 and voice log information D5 that indicates the work status of worker P, which is input by voice via the voice input unit 12 by worker P, in association with time. This allows the currency handling device 1 to record not only device log information D4, but also voice log information D5 entered by worker P that cannot be recorded as device log information D4, and manage this information together with the device log information D4. Therefore, compared to conventional methods, more detailed work information by worker P can be stored as log information, making it possible to check past work content, work time, and the like, which was not possible with conventional methods.

[0051] Furthermore, the currency processing device 1 according to the first embodiment outputs the device log information D4 and the voice log information D5 recorded in the storage 142 in chronological order according to time. This allows the worker P to create a work record after completing a task with great ease. Furthermore, the currency processing device 1 according to the first embodiment can automatically create a work record that includes information about the worker P by inputting the worker P's affiliation and name as voice log information and converting it into text data. Note that, without being limited to this, in other embodiments, the currency processing device 1 may generate a work record that includes information about the worker P by associating information indicating the worker P's authentication with the voice log information D5. Associating the voice log information D5 with the worker P allows the person who performed the task to be identified later. This allows future personnel to check the status of the work with the current personnel if a similar event occurs in the future, thereby improving future work efficiency and work quality.

[0052] Furthermore, the currency handling device 1 according to the first embodiment can prevent impersonation of the worker P by authenticating the worker P based on the voice input of the worker P. Note that the currency handling device 1 according to the first embodiment performs authentication based on the voice features of the worker P and the content of the speech, but this is not limited to this. For example, the currency handling device 1 according to other embodiments may perform authentication based only on the voice features of the worker P, or may perform authentication by matching the spoken affiliation with the name.

[0053] Furthermore, the currency handling device 1 according to the first embodiment can switch the steps of the guidance information D3 displayed on the display operation unit 11, which the worker P checks while working, by voice input. This eliminates the need for the currency handling device 1 to display a large amount of information on a single screen, making it easier to see. Furthermore, because the display content can be changed for each step, the worker P can clearly recognize the task he or she is currently performing, reducing the risk of forgetting to perform a task or performing an incorrect task.

[0054] Other Embodiments Although one embodiment has been described in detail above with reference to the drawings, the specific configuration is not limited to the above, and various design modifications are possible. That is, in other embodiments, the order of the above-described processes may be changed as appropriate. Furthermore, some processes may be executed in parallel. The terminal 10 according to the above-described embodiment may be configured by a single computer, or may be configured by dividing the configuration of the terminal 10 into multiple computers that cooperate with each other to function as the terminal 10.
