[0010] (Embodiment) (Network configuration of item recovery system 1) Figure 1 shows an example of the network configuration of the item recovery system 1 according to this embodiment. The item recovery system 1 is introduced to various affiliated stores. Various affiliated stores include, for example, retail stores and restaurants. Retail stores include, for example, supermarkets, convenience stores, drugstores, discount stores, department stores, and general merchandise stores. Restaurants include fast food restaurants, restaurants, bars, cafes, diners, and food courts.

[0011] As shown in Figure 1, the item recovery system 1 comprises a volume reduction recovery device 10, a store terminal 20, a registration and settlement device 30, a recovery management server 100, a homepage server 110, a headquarters terminal 120, and an end-user terminal 130. Each device is connected via a network 180 for communication.

[0012] Each device is a computer device equipped with a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), a communication unit, etc. The network 180 is a LAN (Local Area Network) or a WAN (Wide Area Network), which may be wired or wireless.

[0013] The volume reduction and collection device 10 is installed for each of a plurality of stores St. The volume reduction and collection device 10 is a device for collecting PET bottles as recyclable items. Specifically, the volume reduction and collection device 10 reduces the volume of empty PET bottles put in by customers who come to the store St and stores them. When the volume reduction and collection device 10 collects PET bottles, it transmits collection information including the content of the collected items to the collection management server 100.

[0014] The stores St are all stores of the same series. In this embodiment, the store St is, for example, a convenience store in the same series. The location where the volume reduction and collection device 10 is installed may be inside the building of the store St or outdoors such as under the eaves of the building of the store St. Note that one or more volume reduction and collection devices 10 are arranged inside the store St.

[0015] The store terminal 20 is a computer device such as a personal computer arranged inside the store St. The store terminal 20 can access the collection management server 100 and display a screen based on the collection information. Also, the store terminal 20 can access the homepage server 110 and display various homepages.

[0016] Furthermore, the store terminal 20 stores various information necessary for transactions, such as the product master. This information includes the product master, a file that stores product information such as product identification information (e.g., JAN (Japanese Article Number) code), product name, and sales price for each product. The product master also includes product identification information, product name, and unit price (price per gram) for products that require weighing, not just fixed-price products. In addition to the product master, the store terminal 20 also stores various other information such as inventory status, sales history, and deposit / withdrawal records. The store terminal 20 also stores information related to special sales and member information.

[0017] The registration and settlement device 30 registers and settles payments for goods. Specifically, the registration and settlement device 30 is a POS (Point of Sales) terminal device. The registration and settlement device 30 comprises a registration unit and a settlement unit. The registration unit performs a registration process to register goods. In the registration process, registration information for the goods purchased by the customer is generated by acquiring various information from the store terminal 20. The settlement unit performs a settlement process based on the registration information generated in the registration process. One or more registration and settlement devices 30 are installed in the store St.

[0018] The collection management server 100 is an example of a management device. The collection management server 100 is, for example, a Web (World Wide Web) server operated by a company that provides the volume reduction and collection device 10. The collection management server 100 manages the collection information received from the volume reduction and collection device 10. Specifically, the collection management server 100 has a collection information database and manages (stores) collection information for each store St. The collection information includes, for example, information indicating the amount of PET bottles collected by the volume reduction and collection device 10, and information regarding the operating status of the volume reduction and collection device 10.

[0019] The homepage server 110 is a web server operated by the company that provides the homepage. Homepages are created for each company that operates a chain of stores. Homepages may also be created for each chain of stores or for each store St. The homepage server 110 transmits information for displaying the homepage to other devices (for example, store terminals 20, headquarters terminals 120, end-user terminals 130, etc.) in response to viewing requests from those other devices. The other devices then display the homepage based on the information they receive.

[0020] Furthermore, the homepage server 110 can, for example, obtain collection information managed by the collection management server 100 via a Web (World Wide Web) API (Application Programming Interface) and display a screen based on the collection information on the homepage.

[0021] The headquarters terminal 120 is a computer device operated and viewed by staff at the headquarters (e.g., the head office or a branch office) that manages the stores St. The headquarters is the organization that controls and manages the stores St of each affiliated store. The headquarters terminal 120 can be, for example, a personal computer, a smartphone, or a tablet device. The headquarters terminal 120 can access the collection management server 100 and display a screen based on collection information. The headquarters terminal 120 can also access the homepage server 110 and display various homepages.

[0022] The end-user terminal 130 is a computer device operated and viewed by end-users such as customers. Examples of end-user terminals 130 include personal computers, smartphones, and tablet devices. The end-user terminal 130 can access the homepage server 110 and display the homepage of a company that operates a business related to store St.

[0023] (Configuration of the volume reduction and recovery device 10) Next, the configuration of the volume reduction and recovery device 10 will be described with reference to Figures 2 and 3. Figure 2 shows an example of the external and internal configurations of the volume reduction and recovery device 10.

[0024] Figure 2(A) is a front view of the volume reduction and recovery device 10. Figure 2(B) is a side view of the volume reduction and recovery device 10. As shown in Figure 2, the volume reduction and recovery device 10 includes a human presence sensor HS, a touch panel display unit TP, and a recovery mechanism unit 200.

[0025] The human presence sensor HS detects a person present in front of the volume reduction and recovery device 10. The human presence sensor HS is, for example, an infrared sensor that detects a person by detecting infrared radiation emitted from body heat.

[0026] The touch panel display unit TP displays a screen and accepts operation input. When a person is detected by the human presence sensor HS, the touch panel display unit TP displays a guidance screen regarding the insertion of item A (for example, an empty plastic bottle). The guidance screen is, for example, a screen prompting the user to insert item A into the container insertion unit 210. The touch panel display unit TP also accepts the press of an insertion completion button when the insertion is complete. In addition, along with displaying the guidance screen, the volume reduction and recovery device 10 outputs an announcement from the voice output unit 304 (Figure 3) prompting the user to insert item A.

[0027] The recovery mechanism 200 includes a container input section 210, a volume reduction section 220, and a container storage section 230. The container loading section 210 includes an outer door 211, a mounting section 212, and an inner door 213. The outer door 211 is equipped with a mechanism that allows it to be opened and closed. When a person is detected by the motion sensor HS, the outer door 211 opens from the closed state. When the outer door 211 is open, it becomes possible to insert item A. Once item A is inserted and the touch panel display unit TP receives the insertion completion button from the customer, the outer door 211 closes from the open state.

[0028] The loading section 212 is where item A is placed. Specifically, the loading section 212 is where item A is placed when the outer door 211 is open. The volume reduction and recovery device 10 is equipped with various sensors 303 (Figure 3). The various sensors 303 include, for example, an optical sensor, a metal sensor, a weighing device, and an imaging device. The various sensors 303 are used to determine whether or not the loaded item A (item A placed on the loading section 212) can be recovered.

[0029] The volume reduction and recovery device 10 determines whether the inserted item A can be recovered based on the detection results of various sensors 303. Specifically, this determination includes determining whether the item is an empty container or whether the container is a plastic container such as a PET bottle. If the volume reduction and recovery device 10 determines that item A cannot be recovered, it notifies the customer to that effect and prompts them to remove the item from the container input section 210.

[0030] The inner door 213 is located downstream of the mounting section 212 in the direction of movement of the item A. The inner door 213 is equipped with an opening and closing mechanism. When the inserted item A is recoverable, the inner door 213 opens from a closed state. When the inner door 213 is open, the item A is output to the volume reduction section 220 via the passage 214.

[0031] The volume reduction unit 220 is located below the container input unit 210. The volume reduction unit 220 reduces the volume of item A output from the passage 214 by crushing it. The volume reduction unit 220 outputs the reduced-volume item A (reduced-volume item RA) to the container storage unit 230.

[0032] The container storage section 230 is located below the volume reduction section 220. The container storage section 230 stores the volume-reduced article RA that has been reduced in volume by the volume reduction section 220. A light-transmitting section 100B (light-transmitting window) is provided on the front side of the main body section 100A of the volume-reduced recovery device 10. The light-transmitting section 100B makes the volume-reduced article RA stored in the container storage section 230 visible from the outside.

[0033] Furthermore, the container storage section 230 is provided on a drawer 100C that can be retracted into the main body section 100A of the device. The drawer 100C is equipped with a pull-out handle 100e and a locking section 100r. When the drawer 100C is stored, the locking section 100r is locked, thus maintaining the stored state. On the other hand, when the locking section 100r is unlocked, a worker can grasp the pull-out handle 100e and pull out the drawer 100C.

[0034] Furthermore, the volume-reduced material RA is placed in a bag inside the container storage section 230. This allows the volume-reduced material RA to be collected along with the bag. Once the volume-reduced material RA is collected, a new bag is placed in the container storage section 230 by the work staff.

[0035] A scanner 240 is provided on the side of the touch panel display unit TP. The scanner 240 reads various codes. These codes include, for example, the member code (member information) displayed on the member card. The volume reduction and recovery device 10 associates the recovered item A with the member information and transmits it to the recovery management server 100, which enables the recovery management server 100 to manage the amount of item A recovered for each member.

[0036] Furthermore, the volume reduction and recovery device 10 is equipped with a cap input section 251 to the side of the container input section 210 (outer door 211). The cap input section 251 is an opening into which the caps of item A (PET bottles) are inserted. The caps inserted from the cap input section 251 are guided to the cap storage section 253 via the cap passage 252 and stored in the cap storage section 253.

[0037] Furthermore, a luggage hook 100f is provided on the front side of the main body 100A of the device. The luggage hook 100f is a hook on which customers can hang bags containing item A that they have brought in, or other hand luggage. By hanging their hand luggage on the luggage hook 100f, customers can easily perform the task of putting in item A.

[0038] Furthermore, a handle 100g for transport is provided on the side of the main body 100A of the device. By grasping the transport handle 100g, the work staff can transport the volume reduction and recovery device 10.

[0039] (Hardware configuration of volume reduction and recovery device 10) Next, the hardware configuration of the volume reduction and recovery device 10 will be explained using Figure 3. Figure 3 shows an example of the hardware configuration of the volume reduction and recovery device 10. As shown in Figure 3, the volume reduction and recovery device 10 includes a CPU 301, a memory 302, various sensors 303, an audio output unit 304, a communication unit 305, a power supply unit 310, a touch panel display unit TP, a scanner 240, and a recovery mechanism unit 200. Each unit is connected to the others via a bus so that they can communicate with each other.

[0040] The CPU 301 is a central processing unit that controls the operation of the volume reduction and recovery device 10 by reading and executing various programs stored in the memory 302. These various programs include recovery control processing programs related to the recovery of goods. Memory 302 is a storage unit such as ROM, RAM, hard disk, flash memory, or SSD (Solid State Drive).

[0041] The various sensors 303 include a human presence sensor HS, a light sensor, a metal sensor, a weighing instrument, and an imaging device. The power supply unit 310 supplies power to its own device (volume reduction and recovery device 10). The power supply unit 310 includes a power supply board, a power plug, a switch, etc. The power supply unit 310 supplies power to its own device when the power plug is plugged into a power outlet located outside the store St, etc., and the switch is ON. In other words, except when the volume reduction and recovery device 10 is malfunctioning, power will not be supplied to the volume reduction and recovery device 10 if the power plug is not plugged into the outlet or if the switch is OFF. The main reason for the lack of power supply is human error by store staff.

[0042] The audio output unit 304 outputs sound. For example, the audio output unit 304 outputs sounds related to the insertion of items, warning sounds, and reading sounds (scanning sounds) when various codes are scanned.

[0043] The communication unit 305 is an interface for sending and receiving information with other devices (such as the store terminal 20, the registration and settlement device 30, and the collection management server 100).

[0044] The CPU 301 executes a recovery control processing program and, based on the detection results of various sensors 303, performs control related to the loading of items (such as control of the touch panel display unit TP, control of the audio output unit 304, opening control of the container loading unit 210, and volume reduction control of the volume reduction unit 220), and also transmits the recovery results to the recovery management server 100 after recovery.

[0045] (Hardware configuration of collection management server 100) Next, the hardware configuration of the collection management server 100 will be explained using Figure 4. Figure 4 shows an example of the hardware configuration of the collection management server 100. As shown in Figure 4, the collection management server 100 comprises a CPU 401, memory 402, and a communication unit 403. Each unit is connected to the others via a bus so that they can communicate with each other.

[0046] The CPU 401 is a central processing unit that controls the operation of the collection management server 100 by reading and executing various programs stored in the memory 402. These various programs include collection management processing programs related to the management of collected items for each volume reduction collection device 10. Memory 402 refers to storage units such as ROM, RAM, hard disk, flash memory, and SSD.

[0047] The communication unit 403 is an interface for sending and receiving information with other devices (such as the volume reduction and recovery device 10, the store terminal 20, the registration and settlement device 30, the homepage server 110, and the headquarters terminal 120).

[0048] The CPU 301 executes a collection management processing program to store collection information for each store St based on the collection results received from the volume reduction collection device 10, and also transmits information based on the collection information to other devices in response to transmission requests from other devices.

[0049] (An example of information stored in the retrieval information database) Next, using Figure 5, we will explain an example of the information stored in the collection information DB provided by the collection management server 100 (the storage unit of the collection management server 100). Figure 5 shows an example of the information stored in the recovery information database. As shown in Figure 5, the recovery information database stores recovery information (an example of information related to recovery) received from the volume reduction recovery device 10. The recovery information includes usage history and operational data. When data is entered into each item shown in the recovery information database, the recovery information is stored as a record.

[0050] (Usage history) The usage history contains information regarding the collection of items. The usage history includes the following items: "Date and Time," "Membership Number," "Store Name," "Terminal Number," "Item," and "Collection Quantity." "Date and Time" indicates the year, month, and time when the information was received from the volume reduction and recovery device 10. The "membership number" represents identification information assigned to the store St that uses the volume reduction and recovery device 10. The "membership number" is associated with the store terminal 20 or the registration and settlement device 30. In other words, the recovery management server 100 can identify the store terminal 20 or the registration and settlement device 30 where the volume reduction and recovery device 10 is located based on the "membership number".

[0051] "Store name" refers to the name of the store's street. The "terminal number" indicates the identification information assigned to the volume reduction and recovery device 10. "Item" refers to the name of the collected item (e.g., PET bottle). "Item" may also include the size of the collected item (e.g., 500 ml, 2 liters). "Collection amount" indicates the quantity (number of items) of items collected.

[0052] (Operational data) The operational data is information regarding the operation of the volume reduction and recovery device 10. The operational data includes the following items: "power supply," "human motion sensor," "panel operation," "full-capacity error release operation," "time of occurrence of non-use factor," and "time of release of non-use factor." "Power" indicates whether the power to the volume reduction and recovery device 10 is ON or OFF. The recovery management server 100 checks for communication abnormalities and the power status of the volume reduction and recovery device 10 by communicating with the volume reduction and recovery device 10 periodically. While the volume reduction and recovery device 10 is running (when the power is ON), it periodically (for example, every 5 minutes or at a fixed time) sends a power signal to the recovery management server 100 indicating that it is running.

[0053] Furthermore, if an error occurs, the volume reduction and recovery device 10 sends an error signal to the recovery management server 100 according to the type of error. This allows the recovery management server 100 to determine not only whether the device is powered on, but also whether an error has occurred. In the diagram, "power ON" indicates the reception of a power signal. The power signal is transmitted periodically (for example, every 5 minutes) from the volume reduction and recovery device 10, as well as when an item is recovered or when the touch panel display unit TP is operated without an item being recovered.

[0054] Furthermore, the power-on signal is not limited to being transmitted unidirectionally from the volume-reducing recovery device 10. For example, the recovery management server 100 may send a confirmation signal to the volume-reducing recovery device 10, and the volume-reducing recovery device 10 may send a signal in response to that signal. The response signal may also include information indicating the status of the volume-reducing recovery device 10 (whether it is functioning normally or has an error).

[0055] The "human presence sensor" is an example of an event that occurs in the volume reduction and recovery device 10. It displays either ON, indicating that a person (or animal) has been detected, or OFF, indicating that no person has been detected.

[0056] "Panel operation" is an example of an event that may occur in the volume reduction and recovery device 10. It indicates whether or not a predetermined operation is accepted from the customer when the volume reduction and recovery device 10 experiences an error. Errors include full-fill errors and stagnation errors. A full-fill error occurs when the volume reduction items RA in the container storage section 230 become full. A stagnation error occurs when items become stagnant (clogging) in the volume reduction and recovery device 10. If an error occurs, the volume reduction and recovery device 10 will not accept the input of items (will not open the outer door 211) even if a person is detected by the motion sensor.

[0057] From the customer's perspective, even though they are standing in front of the volume reduction and recovery device 10, the outer door 211 will not open. Therefore, the customer may try to insert items by operating the touch panel display unit TP. Accordingly, the predetermined operation is defined as a predetermined operation (for example, a touch operation on the screen) that the touch panel display unit TP accepts in the event of an error. "Panel operation" is indicated as "yes" when the predetermined operation is accepted in the absence of item recovery.

[0058] "Full Error Clearing Operation" indicates whether or not an operation to clear the full error has been performed. The full error clearing operation involves a store employee collecting the volume-reducing item RA from the container storage section 230, setting a new bag, and pressing the designated error clearing button. If the error clearing button is pressed, "Full Error Clearing Operation" will be "Yes".

[0059] The "Time of Occurrence of Non-Use Factor" indicates the time when the volume recovery device 10 is determined to be in a non-use state (error or power off). For example, the "Time of Occurrence of Non-Use Factor" indicates the time when an error signal is received from the volume recovery device 10. The error signal is a signal corresponding to the type of error that occurred in the volume recovery device 10 (e.g., full error or stagnant error). The error signal is transmitted from the volume recovery device 10 at the time the error occurs. The "Time of Occurrence of Non-Use Factor" also includes the time when it is determined that the power is off because no power-on signal has been received for a predetermined period of time.

[0060] The "Time of Release of Non-Use Factor" indicates the time when the non-use state was released. For example, the "Time of Release of Non-Use Factor" indicates the time when an error release notification was received from the volume reduction and recovery device 10. The error release notification is a notification corresponding to the type of error. The error release notification is sent from the volume reduction and recovery device 10 at the time when the error is released and recovery is completed. In the case of power off, it includes the time when a power-on signal was received after it was determined that the power was off.

[0061] Next, we will explain each of the recovery information items 501 to 505 stored in the recovery information database.

[0062] (Recovery information 501a, 501b: Recovery OK) Collection information 501a and 501b indicate that the PET bottle was successfully collected. For example, collection information 501a indicates that one PET bottle was collected at Tn001 (terminal number) of XX Mart XX store at 8:22 AM on June 30, 2024. Collection information 501a also indicates that the power is "ON" due to the reception of a power signal, and that the motion sensor is also "ON" because the customer performed the insertion operation. Furthermore, collection information 501a indicates that there was no error, so panel operation was "yes," and the operation to clear the full error was "no."

[0063] (Recovery Information 502: Power is on) Retrieval information 502 indicates that a power-on signal was received from the volume reduction and recovery device 10. Specifically, retrieval information 502 indicates that the power is "ON" because a power-on signal was received from Tn001 (terminal number) of XX Mart XX store at 10:10 on June 30, 2024. Retrieval information 502 indicates that no items were inserted and no errors occurred, therefore, the items, recovered amount, motion sensor, panel operation, and full error clearing operation are all "none".

[0064] (Recall Information 503: Power OFF) Retrieval information 503 indicates that the power-on signal for the volume reduction and retrieval device 10 was not received. For example, retrieval information 503 indicates that for Tn001 (terminal number) of XX Mart XX store, the power-on signal was not received at 10:30 on June 30, 2024, which is scheduled to be sent periodically (for example, every 5 minutes), meaning that the power was considered to be "OFF". Retrieval information 502 indicates that no items were inserted and no errors occurred, so the item, retrieved amount, motion sensor, panel operation, and full error clearing operation are all "none".

[0065] (Retrieval information 504: Error) Retrieval information 504 indicates that an error occurred in the volume reduction and retrieval device 10 due to customer operation, such as foreign object insertion. Specifically, retrieval information 504 indicates that a customer operated the panel from Tn035 (terminal number) of XX Store XX Branch at 11:15 on June 30, 2024. The motion sensor shows "ON" because the customer is in front of the volume reduction and retrieval device 10. In addition, retrieval information 502 shows "none" for both item and retrieved quantity because no items were inserted. Furthermore, retrieval information 502 also shows "none" for the operation to clear the full error. The retrieval management server 100 determines that an error has occurred because no items were retrieved, the motion sensor is "ON", and there was a panel operation. The retrieval management server 100 can also determine the type of error from the usage history and operational data. For this reason, the retrieval management server 100 may also store the type of error in the retrieval information DB. For example, the type of error may be included in the "Remarks" column of the retrieval information database.

[0066] (Retrieval information 505: Full capacity error cleared) Retrieval information 505 indicates the release of a full-capacity error. For example, retrieval information 505 indicates that at 11:40 AM on June 30, 2024, a release operation for a full-capacity error was performed from Tn035 (terminal number) of XX Store XX Branch. The motion sensor indicates "ON" because a store staff member retrieved the volume-reduced items RA from the front of the volume-reducing retrieval device 10. In addition, retrieval information 502 indicates "none" for both the item and the amount retrieved because no items were put in. Furthermore, it also indicates "none" for panel operation.

[0067] (An example of the functional configuration of the collection management server 100) Figure 6 is a block diagram showing an example of the functional configuration of the collection management server 100. As shown in Figure 6, the collection management server 100 includes an acquisition unit 601, a discrimination unit 602, an output unit 603, an extraction unit 604, and a calculation unit 605. Each functional unit is implemented by the CPU 401. That is, the CPU 401 implements each functional unit by executing the collection management processing program according to this embodiment.

[0068] (Acquisition part 601) The acquisition unit 601 acquires recovery information (Figure 5) from the volume reduction and recovery device 10. The recovery information includes usage history and operational data. Usage history is acquired when an item (PET bottle) is recovered. Operational data is acquired at periodic times when a power supply signal is transmitted, and when an operation (panel operation, release operation) occurs in the event of an error. The acquisition unit 601 also acquires error signals from the volume reduction and recovery device 10. The error signals are signals corresponding to the type of error that occurred in the volume reduction and recovery device 10 (for example, a full error or a stagnant error). The error signals are transmitted from the volume reduction and recovery device 10 when an error occurs.

[0069] (Discrimination unit 602) The discrimination unit 602 determines the operating status based on the recovery information acquired by the acquisition unit 601. The operating status includes, for example, an in-use status in which items (PET bottles) can be recovered, and an in-use status in which items cannot be recovered. The discrimination unit 602 determines whether the device is in use or in an in-use status based on the usage history and operating data. An in-use status is a period during which the device cannot operate, such as when the power is "OFF", when there is a full-capacity error, or when there is a stagnant error. The discrimination unit 602 can determine the in-use status related to a full-capacity error or a stagnant error based on the error signal.

[0070] (Output section 603) The output unit 603 outputs information indicating the operating status determined by the discrimination unit 602. For example, if the discrimination unit 602 determines that the unit is in unused condition, the output unit 603 outputs information indicating the unused condition (hereinafter referred to as "unused information").

[0071] The destinations for the non-use information are the store terminal 20 and registration / settlement device 30 of the store St where the volume reduction / recovery device 10 is located, and the headquarters terminal 120 of the headquarters that manages the store St. Upon receiving the non-use information, the store terminal 20, registration / settlement device 30, and headquarters terminal 120 notify that the volume reduction / recovery device 10 at their respective stores is not in use. This allows store staff and headquarters staff to be aware that the volume reduction / recovery device 10 is not in use.

[0072] Furthermore, if the discrimination unit 602 determines that the device is in use, the output unit 603 can also output information indicating that it is in use. In this case, when the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 receive the usage information, they can notify the store that its volume reduction and recovery device 10 is in use.

[0073] Furthermore, the output unit 603 not only outputs information indicating the operating status, but can also output usage history and operating data corresponding to the target volume reduction and recovery device 10. The destination for the usage history and operating data is, for example, a store terminal 20 or a headquarters terminal 120. This allows the store terminal 20 and the headquarters terminal 120 to display the usage history and operating data.

[0074] (Outputs non-use information if the non-use status continues for a specified period.) The output unit 603 outputs non-use information when the volume reduction and recovery device 10 remains unused for a predetermined period of time. Specifically, the output unit 603 outputs non-use information if it does not receive a power supply signal from the volume reduction and recovery device 10 for a predetermined period (e.g., 15 minutes). In addition, the output unit 603 outputs non-use information if an error occurs and the error is not resolved within a predetermined period of time. This makes it possible to avoid outputting non-use information in the event of a temporary non-use state. Note that the timing of outputting non-use information is not limited to the timing when the predetermined period of non-use has continued, but may also be the timing when the non-use state occurs. In other words, the output unit 603 may output non-use information without waiting for the predetermined period to elapse.

[0075] (Identifying the factors causing the non-use state) The discrimination unit 602 determines the cause of the non-use state (hereinafter referred to as "non-use cause") based on the recovery information. The non-use cause is one of the following: power OFF, full error, or stagnant error. If the power item in the operation data is "OFF", the discrimination unit 602 determines that power OFF is the non-use cause.

[0076] Furthermore, the discrimination unit 602 determines that the reason for non-use is an error if there is no item retrieval and a panel operation is received. Specifically, the discrimination unit 602 determines that the reason for non-use is an error if the item item in the usage history is "none", the motion sensor item is "ON", and the panel operation item is "present".

[0077] Errors are cleared when a bag is replaced in the case of a full error, or when items are recovered in the case of a stagnant error. When the volume reduction and recovery device 10 is restored after an error is cleared, it sends an error clearing notification to the recovery management server 100 according to the type of error. This allows the recovery management server 100 to manage the status of the volume reduction and recovery device 10 in real time. If the device were to wait for periodic communication, such as a power-on signal, to receive data indicating that an error clearing operation has been performed, there is a risk that the actual status of the volume reduction and recovery device 10 and the status managed by the recovery management server 100 may temporarily differ. Furthermore, this difference may persist for a long period of time in some cases. In this embodiment, since an error clearing notification according to the type of error is sent in real time, such discrepancies are minimized.

[0078] Furthermore, the discrimination unit 602 can also determine whether the reason for non-use is a full-capacity error or a stagnant error based on the usage history and operational data. For example, if operational data indicating an operation to clear a full-capacity error is received, the discrimination unit 602 can determine that the error was a full-capacity error. Also, if usage history is received during an error, the discrimination unit 602 can determine that the error was a stagnant error.

[0079] The output unit 603 outputs non-use information along with the reason for non-use. The store terminal 20, registration and settlement device 30, and headquarters terminal 120 corresponding to the volume reduction and recovery device 10 notify that the volume reduction and recovery device 10 is in a non-use state and the reason for this (power off or error). This allows store staff and headquarters staff to understand that the volume reduction and recovery device 10 is in a non-use state and the reason for non-use.

[0080] Furthermore, if the volume reduction and recovery device 10 has an error that allows for the identification of the reason for non-use (such as a full error or a stagnant error), the store terminal 20 or the registration and payment device 30 may receive an error signal directly from the volume reduction and recovery device 10 without going through the recovery management server 100, and report the error indicated by the error signal. This allows the store terminal 20 or the registration and payment device 30 to report errors that require action by store staff without going through the recovery management server 100, in the event of a full error or a stagnant error.

[0081] (Storage of information regarding unused status) The retrieval management server 100 (storage unit) stores information regarding the unused state when it is determined by the discrimination unit 602 to be in an unused state. The information regarding the unused state includes the cause of the unused state (unusage factor), events that occurred during the unused state, and the duration of the unused state. The unused history information includes, as described above, one of the following as the cause of the unused state: power off, full error, or stagnant error. In addition, events that occurred during the unused state include the detection results of the human presence sensor and the detection results of panel operation. For example, the information regarding the unused state includes retrieval information indicating the unused state (for example, retrieval information 503 (power off) or retrieval information 504 (full error or stagnant error) in Figure 5).

[0082] (Output of non-use history information: Example 1) The output unit 603 outputs non-use history information for a volume reduction and recovery device 10 based on information about the non-use status of the volume reduction and recovery device 10 stored in the memory unit. The non-use history information is history information related to non-use, and includes, for example, the history of the factors causing non-use, the events that occurred during the non-use state, and the period of non-use. The output destination for the non-use history information is, for example, the store terminal 20, the registration and settlement device 30, or the headquarters terminal 120. As a result, for example, the headquarters terminal 120 can display the non-use report screen 1310 (Figure 13A(A)) and the event screen 1320 (Figure 13A(B)), which will be described later.

[0083] (Output of non-use history information: Example 2) The output unit 603 outputs comparable unused history information for the multiple volume reduction and recovery devices 10 based on information about the unused status of the multiple volume reduction and recovery devices 10 stored in the memory unit. This makes it possible, for example, for the headquarters terminal 120 to display the store comparison screen 1330 (Figure 13B), which will be described later.

[0084] (An example of settlement processing performed by the volume reduction and recovery device 10) Next, using Figure 7, we will explain the settlement process performed by the volume reduction and recovery device 10. Figure 7 is a flowchart showing an example of the processing related to the transmission of recovery information performed by the volume reduction and recovery device 10. The processing shown in Figure 7 is performed during the control cycle of the CPU 301 of the volume reduction and recovery device 10.

[0085] In Figure 7, the volume reduction and recovery device 10 determines, for example, whether or not it is a preset energization signal transmission timing (step S701). The energization signal transmission timing is, for example, at 5-minute intervals. If it is not an energization signal transmission timing (step S701: NO), the volume reduction and recovery device 10 proceeds to the process in step S703. On the other hand, if it is an energization signal transmission timing (step S701: Yes), the volume reduction and recovery device 10 transmits an energization signal to the recovery management server 100 (step S702).

[0086] The volume reduction and recovery device 10 then determines whether or not a person has been detected by the human presence sensor HS (step S703). If no person is detected by the human presence sensor HS (step S703: NO), the volume reduction and recovery device 10 terminates the series of processes.

[0087] On the other hand, if a person is detected by the motion sensor HS (step S703: Yes), the volume reduction and recovery device 10 determines whether or not an error is occurring (step S704). If there is no error (step S704: No), the volume reduction and recovery device 10 uses the touch panel display unit TP and the voice output unit 304 to provide guidance regarding the insertion of items (PET bottles) and accepts the operation to start insertion, thereby opening the outer door 211 (step S705).

[0088] Furthermore, the opening of the outer door 211 is conditional on receiving an operation from the operator (customer) to start the loading process. If the outer door 211 were to open without such an operation, it is conceivable that the outer door 211 could open simply by a person passing in front of the volume reduction and recovery device 10. In such a case, there is a risk that foreign objects other than PET bottles may be put into the volume reduction and recovery device 10, such as someone mistaking it for a trash can and putting garbage into it. Also, if foreign objects are put in, the outer door 211 may remain open, in which case the volume reduction and recovery device 10 would be unable to operate.

[0089] Furthermore, by setting the opening of the outer door 211 as a condition for starting the input operation, the volume reduction and recovery device 10 can determine that a foreign object has been input if the input start operation is received but the outer door 211 does not close. In addition, if the volume reduction and recovery device 10 receives the input start operation but no items are input within a predetermined time, it can close the outer door 211. The volume reduction and recovery device 10 can obtain a history of such operations (foreign object input, no items input, etc.).

[0090] The volume reduction and recovery device 10 then reduces the volume of the inserted item and recovers it (step S706). When recovering an item, the volume reduction and recovery device 10 detects the item, closes the outer door 211, and determines whether the inserted item is an empty PET bottle or not. If the volume reduction and recovery device 10 determines that it is not an empty PET bottle, for example, if it determines that it is a foreign object such as an empty can or a PET bottle containing contents, it opens the outer door 211 and prompts the removal of the item (foreign object). In this case, the volume reduction and recovery device 10 also outputs a history indicating that a foreign object was inserted, or an error signal if an error occurs, to the store terminal 20 or the recovery management server 100. Next, the volume reduction and recovery device 10 sends the usage history to the recovery management server 100 (step S707) and ends the series of processes.

[0091] In step S704, if the volume reduction and recovery device 10 is experiencing an error (step S704: Yes), it determines whether or not it has received a full error release operation (step S708). If it has received a full error release operation (step S708: Yes), the volume reduction and recovery device 10 sends operational data indicating "release operation performed" to the recovery management server 100 (step S709), and terminates the series of processes.

[0092] On the other hand, if the full error clearing operation is not accepted (step S708: NO), the volume reduction and recovery device 10 determines whether or not the panel operation has been accepted (step S710). If the panel operation has been accepted (step S710: Yes), the volume reduction and recovery device 10 sends operational data indicating "panel operation" to the recovery management server 100 (step S711), and terminates the series of processes.

[0093] On the other hand, if the panel operation is not accepted (step S710: NO), the volume reduction and recovery device 10 sends operational data indicating "no panel operation" to the recovery management server 100 (step S712), and terminates the series of processes.

[0094] (An example of the process performed by the collection management server 100) Next, we will explain the processes performed by the collection management server 100 using Figures 8 to 11. Figure 8 is a flowchart showing an example of the collection management process performed by the collection management server 100. Note that each process shown in Figures 8 to 11 is performed according to the control cycle of the CPU 401 equipped in the collection management server 100.

[0095] In Figure 8, the collection management server 100 performs collection information reception processing (Figure 9) (step S801). Collection information reception processing is performed by receiving collection information from the volume reduction collection device 10. Next, the collection management server 100 performs unused information transmission processing (Figure 10) (step S802). Then, the collection management server 100 performs error clearing processing (Figure 11) (step S803). Furthermore, the collection management server 100 performs aggregated result transmission processing (Figure 15) (step S804), and the series of processes ends.

[0096] (Receipt processing of retrieval information, etc.) Figure 9 is a flowchart illustrating an example of the collection information reception process performed by the collection management server 100. In Figure 9, the collection management server 100 determines whether or not it has received collection information (either usage history or operational data) (step S901). If collection information is not received (step S901: NO), the collection management server 100 proceeds to step S904. On the other hand, if collection information is received (step S901: Yes), the collection management server 100 stores the received collection information in the collection information DB (Figure 5) (step S902).

[0097] Here, the recovery management server 100 measures a period (power outage determination period) for each volume reduction recovery device 10 to determine whether or not the volume reduction recovery device 10 is powered on. The measured period is used to determine whether or not 15 minutes have passed since the last power-on signal was received. If the recovery management server 100 does not receive a new power-on signal within 15 minutes of the last power-on signal being received, it determines that the volume reduction recovery device 10 is not powered on. On the other hand, if the recovery management server 100 receives a new power-on signal within 15 minutes of the last power-on signal being received, it determines that the volume reduction recovery device 10 is powered on.

[0098] Furthermore, upon receiving recovery information, the recovery management server 100 can determine that the volume reduction recovery device 10 is in a communication-enabled state (powered on), regardless of whether or not there is a power-on signal. For this reason, after processing in step S902, the recovery management server 100 resets (sets to zero) the power-off determination period and starts remeasuring the determination period (step S903).

[0099] Next, the retrieval management server 100 determines whether or not it has received a power-on signal (step S904). If it does not receive a power-on signal (step S904: NO), the retrieval management server 100 proceeds to step S906.

[0100] On the other hand, if a power-on signal is received (step S904: Yes), for example, if there are no abnormalities and the system is in standby mode, the recovery management server 100 resets the power-off determination period and starts remeasuring the determination period, similar to step S903 (step S905).

[0101] The retrieval management server 100 then determines whether or not it has received an error signal (step S906). If it does not receive an error signal (step S906: NO), the retrieval management server 100 terminates the series of processes and proceeds to the unused information transmission process (Figure 10).

[0102] Here, if the volume reduction and recovery device 10 remains inoperable due to an error for an extended period, information is sent to the store terminal 20 or the like to prompt the store clerk St to clear the error. For this reason, the recovery management server 100 measures a period (error determination period) to determine whether the error has persisted for a predetermined period. The error determination period is the period used to determine whether 15 minutes have passed since the receipt of the error signal (the occurrence of the error) without the error being cleared. If the recovery management server 100 does not receive an error clearing notification for the error within 15 minutes of receiving the error signal, it sends information to the store clerk St to prompt the error to clear the error.

[0103] For these reasons, if the collection management server 100 receives an error signal in step S906 (step S906: Yes), it starts measuring the error judgment period (step S907). The error judgment period is measured separately for each type of error. For example, the error judgment period for a full error and the error judgment period for a stagnant error are measured separately.

[0104] After the processing in step S907, the recovery management server 100 completes the series of processes and proceeds to the non-use information transmission process (Figure 10).

[0105] (Processing of sending unused information) Figure 10 is a flowchart showing an example of the non-use information transmission process performed by the collection management server 100. In Figure 10, the collection management server 100 determines whether a predetermined period (e.g., 15 minutes) has elapsed for the power outage determination period (step S1001). The power outage determination period is a period measured to determine if the volume reduction and recovery device 10 is not powered on if no new collection information or power-on signal is received within 15 minutes of receiving the previous collection information or power-on signal. If the predetermined period for the power outage determination period has not elapsed (step S1001: NO), the collection management server 100 proceeds to step S1004.

[0106] On the other hand, if the power outage detection period has elapsed for a predetermined period (step S1001: Yes), the collection management server 100 transmits information indicating that the power is OFF as non-use information to other devices corresponding to the volume reduction collection device 10 (store terminal 20, registration and settlement device 30, and headquarters terminal 120) (step S1002). Specifically, the collection management server 100 determines that the volume reduction collection device 10 is not powered on (unable to transmit information) because it has not received new collection information or a power-on signal within 15 minutes of receiving the previous collection information or power-on signal, and transmits information indicating that the power is OFF to the terminals in the store St and the headquarters terminal 120. This allows store employees to be prompted to check the power status and headquarters staff to be presented with the operational status of the stores.

[0107] Then, the recovery management server 100 resets the measured value of the power outage detection period and starts remeasuring the power outage detection period (step S1003). As a result, if another 15 minutes have passed with the power still OFF, it can transmit information indicating that the power is OFF again.

[0108] Next, the recovery management server 100 determines whether or not the error determination period is being measured (step S1004). The error determination period is a period measured to determine if the volume reduction recovery device 10 is not powered on if no new recovery information or power-on signal is received within 15 minutes of the previous recovery information or power-on signal being received. If the error determination period is not being measured (step S1004: NO), the recovery management server 100 terminates the series of processes and proceeds to the error clearing process (Figure 11).

[0109] On the other hand, if the error judgment period is still being measured (Step S1004: Yes), the retrieval management server 100 determines whether the predetermined period (for example, 15 minutes) has elapsed (Step S1005). If the predetermined period has not elapsed (Step S1005: No), the retrieval management server 100 terminates the series of processes and proceeds to the error clearing process (Figure 11).

[0110] On the other hand, if the error detection period has elapsed for a predetermined period (step S1005: Yes), that is, if no error clearing notification for the error is received within 15 minutes of receiving the error signal, the recovery management server 100 transmits information indicating the error as non-use information to other devices corresponding to the volume reduction recovery device 10 (store terminal 20, registration and settlement device 30, and headquarters terminal 120) (step S1006). The recovery management server 100 then resets the measured value of the error detection period and starts remeasuring the error detection period (step S1007). As a result, if another 15 minutes have passed without the error being resolved, the server can transmit information indicating the error again.

[0111] (Error clearing process) Figure 11 is a flowchart showing an example of the error clearing process performed by the collection management server 100. In Figure 11, the collection management server 100 determines whether or not an error is occurring (step S1101). If there is no error (step S1101: NO), the collection management server 100 terminates the series of processes and proceeds to the aggregation result transmission process (Figure 15).

[0112] On the other hand, if an error occurs (step S1101: Yes), the retrieval management server 100 determines whether or not it has received an error clearing notification (step S1102). If it does not receive operational data (step S1102: No), the retrieval management server 100 terminates the series of processes and proceeds to the aggregation result transmission process (Figure 15).

[0113] On the other hand, if an error clearing notification is received (step S1102: Yes), the measurement of the error determination period is terminated (step S1103), and the series of processes is terminated.

[0114] (Example of a screen displayed on the headquarters terminal 120) Next, using Figures 12, 13A, and 13B, we will explain examples of screens displayed on the headquarters terminal 120's display. Figures 12, 13A, and 13B show examples of screens displayed on the headquarters terminal 120. Note that the screens shown in Figures 12, 13A, and 13B can also be displayed on other terminals (store terminals 20 and registration / settlement devices 30) after logging in.

[0115] (Browse selection screen 1210) Figure 12(A) shows the viewing selection screen 1210. The viewing selection screen 1210 is displayed, for example, after logging in (after entering a predetermined ID and password) and selecting a predetermined selection button. The viewing selection screen 1210 includes a viewing request button 1211. The viewing request button 1211 includes, for example, a usage history selection button 1211a, a cumulative report selection button 1211b, an unused report selection button 1211c, and a contribution value selection button 1211d.

[0116] When the usage history selection button 1211a is selected, a list screen (not shown) of the usage history of the store (Figure 5) is displayed. Furthermore, when the cumulative report selection button 1211b is selected, the system transitions to the cumulative report screen 1220 shown in Figure 12(B). When the "Unused Report" selection button 1211c is selected, the system transitions to the "Unused Report" screen 1310 shown in Figure 13A(A). When the contribution value selection button 1211d is selected, the screen transitions to the recovery amount - CO2 reduction amount screen 1400 shown in Figure 14.

[0117] (Cumulative report screen 1220) Figure 12(B) shows the cumulative report screen 1220. The cumulative report screen 1220 shows the cumulative values ​​for each store St under the jurisdiction of headquarters. Each cumulative value is a daily value and includes, for example, the total amount of items (PET bottles) collected, the total number of weighings, the total weight of PET bottles, the amount of CO2 reduction, and the contribution value. The total amount of recovered items indicates the total number of items (PET bottles) recovered by the volume reduction and recovery device 10. The total number of weighing operations indicates the total number of times the volume reduction and recovery device 10 performed weighing operations. The total PET weight indicates the total weight of the items recovered by the volume reduction and recovery device 10. The CO2 reduction amount represents the total amount of carbon dioxide reduced by reducing the volume of goods. The contribution value represents the amount of CO2 reduction converted into a figure. Details of the contribution value will be described later.

[0118] Furthermore, the cumulative report screen 1220 includes a monthly summary button 1221 and a total store cumulative button 122. The monthly summary button 1221 allows switching to a screen that displays each cumulative value on a monthly basis. The total store cumulative button 122 allows switching to a screen that displays all cumulative values ​​for each store accumulated together. Note that the switchable screens are not limited to these; screens that display data on a yearly basis or screens that display data by store St's location area are also possible.

[0119] The usage history (Figure 5) list screen (not shown) and the cumulative report screen 1220 can also display the available time for each store and the total time the device was not in use. This allows each staff member to understand which stores frequently use the volume reduction and recovery device 10 and which stores do not. Therefore, various considerations can be made regarding the volume reduction and recovery device 10 at each store. For example, measures can be taken to encourage use in stores where the device is not used frequently. Also, in stores where the device is frequently used, for example, if there are many full-tank errors, considerations can be made to move the device from a store where it is not used frequently to create a two-unit system.

[0120] Furthermore, if a store that frequently uses the device experiences many full-tank errors, information recommending a volume reduction recovery device 10 with a larger recovery capacity than the current one may be displayed. This would provide manufacturers of the volume reduction recovery device 10 and service providers related to the device 10 with an opportunity to promote sales. Also, if the volume reduction recovery device 10 is a leased item, the leasing company can expect an increase in lease payments due to the increased recovery capacity.

[0121] (Unused Report Screen 1310) Figure 13A(A) shows the unused report screen 1310. The unused report screen 1310 shows the number of occurrences of each unused factor (power off, full error, stagnant error) for a given store (○○ Mart ○○ Store) on a daily basis. This allows headquarters staff to easily understand the unused factors for a given store on a given day. The unused report screen 1310 also includes an item called "Total Unused Time." "Total Unused Time" is the total amount of time the store was in an unused state. This allows headquarters staff to easily understand how much time the store was unusable.

[0122] Furthermore, the unused report screen 1310 includes a display switching button 1311. The display switching button 1311 includes a period calculation button 1311a, a store switching button 1311b, a monthly summary button 1311c, a store comparison button 1311d, and an event switching button 1311e.

[0123] The period calculation button 1311a accepts a switch to a screen that displays the calculation results of the non-use period (the period during which the volume reduction and recovery device 10 cannot operate). The calculation results are, for example, the calculation results of the non-use period for each non-use factor. For example, it is possible to calculate the total time for each non-use factor that occurred, based on the time from the "time of occurrence of non-use factor" to the "time of resolution of non-use factor" stored in the recovery information DB (Figure 5). Specifically, for example, the calculation results are the date and time of each power off or various error (Month Day Hour and Minute ~ Month Day Hour and Minute) and the duration of each power off or various error (Minutes). This calculation may be performed by the recovery management server 100 or by the headquarters terminal 120. By visualizing the total time etc. calculated for each non-use factor in this way, it is possible to easily check when each non-use factor occurred and for how long it was in a non-use state. In particular, the headquarters terminal 120 makes it possible to grasp the superiority or inferiority of store operations at a glance, making it clear which stores should be prioritized for improvement.

[0124] The store switching button 1311b accepts a switch to the unused report screen 1310 of a different store St (for example, store △△) than the store ○○ shown in the diagram. The monthly summary button 1311c accepts a request to switch to a screen that displays monthly summaries. The store comparison button 1311d accepts a switch to a screen that compares the number of occurrences of non-use factors for two or more stores St belonging to the same chain. When the store comparison button 1311d is pressed, the screen transitions to the store comparison screen 1330 shown in Figure 13B. The event switching button 1311e accepts a transition to the event screen 1320 shown in Figure 13A(B).

[0125] (Screenshot 1320) Figure 13A(B) shows the event screen 1320. The event screen 1320 shows events that occurred in a non-use state at a certain store (○○ Mart ○○ Store). Here, we will provide some supplementary information about the extraction unit 604 (Figure 6). The extraction unit 604 extracts events that occurred in the non-use state based on the recovery information. These events are related to the loss of opportunity (chance loss) that could have been recovered if the store had been in use. Specifically, these events are the detection results of the human presence sensor and the detection results of panel operation.

[0126] The extraction unit 604 extracts operational data (for example, part of the collection information 504 in Figure 5) from the collection information stored in the collection information DB that indicates no items were collected, the human motion sensor is "ON", and the panel was "operated".

[0127] The output unit 603 outputs information indicating the events extracted by the extraction unit 604. This enables the headquarters terminal 120 to display the event screen 1320 shown on the event screen 1320.

[0128] Specifically, the event screen 1320 shows the detection result where operational data was obtained indicating that the human presence sensor was "ON" and the panel was "operated". The event screen 1320 also includes a display switching button 1321. The display switching button 1321 includes a time zone switching button 1321a and a store comparison button 1322b. The time zone switching button 1321a accepts a request to switch to a screen that shows the number of times each event has occurred during a specific time period. The store comparison button 1322b accepts a switch to the event screen 1320 of a different store St (for example, store △△) than the store ○○ shown in the diagram.

[0129] In addition to the display switching button 1321 shown in the diagram, the event screen 1320 may also include buttons that allow switching to a screen showing monthly summaries, and buttons that allow switching to a screen comparing events across multiple stores St.

[0130] By displaying this event screen 1320, headquarters staff can understand the opportunity loss (chance loss) that could have been recovered if the equipment had been in use, even when it was not being used. Furthermore, headquarters staff can estimate time periods when demand is expected to be high.

[0131] Furthermore, each staff member can predict when a full-capacity error will occur. For example, if it is predicted that this event occurs frequently during a specific time period when a full-capacity error occurs, staff can be optimized by considering the congestion situation during that time period (actual data from the registration and payment device 30) and the staff shifts. Also, for example, a customer who brings an empty plastic bottle would normally have the bottle collected first before shopping in the store. However, if the plastic bottle collection process cannot be carried out, the customer would have to shop with an empty plastic bottle, which could lead to them not shopping at all (not entering the store) or reducing the number of items they purchase. Therefore, losing the opportunity to collect plastic bottles (an opportunity to improve the contribution value to environmental protection) could lead not only to a loss of collection opportunity but also to a loss of sales related to store usage (customer visits, sales, etc.). In this embodiment, since the period during which the volume reduction and collection device 10 is not operational can be reduced, not only can the loss of collection opportunities be reduced, but sales losses can also be reduced.

[0132] (Store comparison screen 1330) Figure 13B shows the store comparison screen 1330 displayed on the headquarters terminal 120. The store comparison screen 1330 shows a comparison of the unused status of each store in the chain (○○ Mart). In the illustration, the store comparison screen 1330 shows a screen where stores are sorted in descending order of the number of errors that occurred on a certain day (June 30th). The store comparison screen 1330 also includes a display switching button 1331. The display switching button 1331 includes a time order button 1331a and a month order button 1332b.

[0133] The time-based sort button 1331a accepts a switch to a screen where stores are sorted in descending order of total unused time over a user-defined period. The monthly button 1332b allows the user to switch to a screen where stores are sorted in descending order of the number of errors that occurred in a user-defined month.

[0134] (Recovery amount - CO2 reduction amount screen 1400) Figure 14 shows an example of the CO2 Recovery Amount - CO2 Reduction Amount screen 1400. The CO2 Recovery Amount - CO2 Reduction Amount screen 1400 can be displayed without logging in. For example, the CO2 Recovery Amount - CO2 Reduction Amount screen 1400 can be displayed on a homepage. Therefore, the CO2 Recovery Amount - CO2 Reduction Amount screen 1400 can be displayed on the store terminal 20, the headquarters terminal 120, and the end-user terminal 130, respectively. The CO2 Recovery Amount - CO2 Reduction Amount screen 1400 may also be displayed on digital signage.

[0135] The Recovery Amount - CO2 Reduction Amount screen 1400 shows various cumulative values ​​for the current fiscal year. These cumulative values ​​include the total number of collected items (PET bottles), the total amount of CO2 reduction, the total number of stores where the device is installed, the total weight of collected items (PET bottles), and the contribution value absorbed by cedar trees. The total weight of collected items may be calculated based on the number of collected items, or it may be obtained based on the detection results of various sensors 303 (weighing devices) equipped in the volume reduction and recovery device 10.

[0136] Furthermore, the "cumulative number of stores where the volume reduction and recovery device 10 is installed" may exclude stores where the period of non-use (period of inoperability) of the device exceeds a predetermined time. Specifically, if the period of non-use of the volume reduction and recovery device 10 within a predetermined period (for example, one day or one week) exceeds a predetermined time (for example, one hour or more or ten hours or more), the store where the volume reduction and recovery device 10 is installed may be excluded from the "cumulative number of stores where the device is installed." This makes the "cumulative number of stores where the device is installed" more realistic information. Consequently, each store and headquarters can be made more aware of minimizing the time spent experiencing full-capacity errors or foreign object input errors.

[0137] (Regarding the calculation of contribution values) Here, we will explain how the contribution value is calculated. The calculation unit 605 (Figure 6) calculates the contribution value related to environmental conservation based on the amount of collected items included in the collection information. This contribution value is calculated, for example, based on the amount transported by trucks that transport the collected items (PET bottles). Since the PET bottles are reduced in volume by the volume reduction and collection device 10, the number of bottles that can be transported by one truck increases accordingly. For example, if the volume of a PET bottle is reduced to one-third, it becomes possible to transport three times the amount of PET bottles compared to when they are not reduced in volume. This means that three times the amount can be transported in one trip. In other words, it is not necessary to make two trips. Therefore, assuming that the amount of collected reduced-volume PET bottles is equivalent to one truckload, it becomes possible to reduce the amount of carbon dioxide emissions required for two trips.

[0138] The calculation unit 605 calculates the reduced carbon dioxide emissions (hereinafter referred to as "CO2 emission reduction") based on the following values, for example. The ratio at which the volume of an item is reduced in the volume reduction and recovery device 10. • Truck transport capacity (loading volume). • Carbon dioxide emissions generated by truck transportation. • The total amount of items recovered by the volume reduction and recovery device 10.

[0139] Furthermore, in addition to calculating the amount of CO2 emission reduction, the calculation unit 605 converts the CO2 emission reduction into a contribution value. The contribution value is converted into a conversion target such as the amount absorbed by a cedar tree in one year, or the number of 25-meter swimming pools based on their volume. The conversion target may be selected for each company (headquarters or store). For example, an automobile manufacturer could use the mileage of gasoline-powered vehicles as the conversion target, and a home appliance manufacturer could use the usage time of televisions or personal computers as the conversion target. By making the conversion target selectable according to the type of business, the company's employees, stakeholders, and consumers can easily visualize the amount of reduction.

[0140] Furthermore, the calculation unit 605 calculates the cumulative CO2 emission reduction and contribution value based on the recovered amounts. However, the calculation unit 605 can also calculate the CO2 emission reduction and contribution value for each individual recovery amount.

[0141] The output unit 603 outputs the contribution value calculated by the calculation unit 605. This allows the store terminal 20, etc., to display the converted value as shown on the Recovery Amount - CO2 Reduction Amount screen 1400.

[0142] Furthermore, the Recovery Amount - CO2 Reduction Amount screen 1400 may be adapted for administrators (head office staff). For example, the "Cumulative Number of Stores with Installations" may increase or decrease according to operational performance. Since it is desirable for administrators to be able to grasp the total number of stores where the volume reduction and recovery device 10 is set up at a glance, the number of stores currently in operation (34 stores) and the total number of stores (35 stores) may be displayed simultaneously, for example, as "34 stores / 35 stores".

[0143] (An example of the cumulative value transmission process performed by the collection management server 100) Next, using Figure 15, we will explain the cumulative value transmission process performed by the collection management server 100. Figure 15 is a flowchart illustrating an example of the cumulative value transmission process performed by the collection management server 100. The process shown in Figure 15 is performed during the control cycle of the CPU 401 in the collection management server 100. Figure 15 also describes the scenario where the collection management server 100 transmits information to the headquarters terminal 120 in response to a viewing request from the headquarters terminal 120. The collection management server 100 performs similar processing when transmitting information to other devices in response to viewing requests from those devices.

[0144] In Figure 15, the collection management server 100 determines whether or not it has received a request to view the usage history from the headquarters terminal 120 by selecting the usage history selection button 1211a (Figure 12(A)) on the headquarters terminal 120 (step S1501). If a request to view the usage history is received (step S1501: Yes), the collection management server 100 identifies the target store St based on the viewing request and extracts the usage history of the target store St (store St under the headquarters) from the collection information DB (Figure 5) (step S1502). Then, the collection management server 100 sends the extracted usage history to the headquarters terminal 120 (step S1503) and ends the series of processes.

[0145] In step S1501, if no request to view the usage history is received (step S1501: NO), the collection management server 100 determines whether or not a request to view the cumulative report has been received from the headquarters terminal 120 by the selection of the cumulative report selection button 1211b (Figure 12(A)) on the headquarters terminal 120 (step S1504). If a request to view the cumulative report is received (step S1504: Yes), the collection management server 100 identifies the target store St based on the viewing request and generates a cumulative report for the target store St (the store St under the headquarters) (step S1505). Then, the collection management server 100 sends the generated cumulative report to the headquarters terminal 120 (step S1506) and terminates the series of processes.

[0146] In step S1504, if no request to view the cumulative report is received (step S1504: NO), the collection management server 100 determines whether or not a request to view the unused report has been received from the headquarters terminal 120 by the selection of the unused report selection button 1211c (Figure 12(A)) on the headquarters terminal 120 (step S1507). If a request to view the unused report is received (step S1507: Yes), the collection management server 100 identifies the target store St based on the viewing request and generates an unused report for the target store St (the store St under the headquarters) (step S1508). Then, the collection management server 100 sends the generated unused report to the headquarters terminal 120 (step S1509) and terminates the series of processes.

[0147] In step S1507, if no request to view the non-use report is received (step S1507: NO), the collection management server 100 determines whether or not a request to view the contribution value has been received from the headquarters terminal 120 by checking whether the contribution value selection button 1211d (Figure 12(A)) is selected on the headquarters terminal 120 (step S1510). If no request to view the contribution value is received (step S1510: NO), the collection management server 100 terminates the series of processes.

[0148] On the other hand, if a request to view contribution values ​​is received (step S1510: Yes), the collection management server 100 identifies the target store St based on the viewing request and obtains (or calculates) the cumulative values ​​for each of the target store St (store St under the headquarters) (step S1511). Then, the collection management server 100 calculates the amount of CO2 emission reduction based on the obtained cumulative values ​​and further calculates the contribution value from the amount of CO2 emission reduction (step S1512). Next, the collection management server 100 sends each of the cumulative values, including the calculated contribution value, to the headquarters terminal 120 (step S1513), and the series of processes ends.

[0149] Furthermore, the calculation of each cumulative value, including contribution values, is not limited to being performed at the time a request to view contribution values ​​is received (in real time). Such calculations may be performed at predetermined times. These predetermined times may be, for example, midnight every day, or every hour.

[0150] Furthermore, the various types of information transmitted from the collection management server 100 (usage history, cumulative report, non-use report) may be transmitted as text data such as CSV (Comma Separated Values).

[0151] As described above, the item recovery system 1 (recovery management server 100) according to this embodiment determines the operating status of the volume reduction recovery device 10 based on the recovery information acquired from the volume reduction recovery device 10, and outputs information indicating the determined operating status. As a result, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can display the operating status of the volume reduction and recovery device 10 under management to each staff member. Therefore, each staff member can understand and analyze the usage and non-use status of the volume reduction and recovery device 10. Consequently, it is possible to prevent a decrease in the efficiency of item recovery by the volume reduction and recovery device 10. In addition, since the period during which the volume reduction and recovery device 10 is not operational (non-use period) can be reduced, the loss of recovery opportunities can be reduced. Furthermore, sales losses associated with the loss of recovery opportunities can also be reduced.

[0152] Furthermore, the recovery management server 100 according to this embodiment determines, based on the recovery information, whether the volume reduction recovery device 10 is in a usable state where the items can be recovered, or in an unused state where the items cannot be recovered. As a result, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can display to each staff member the operating status of the volume reduction and recovery device 10 under management, specifically whether it is in use or not. Therefore, each staff member can understand and analyze the operating status of the volume reduction and recovery device 10. In addition, since the operating rate of the volume reduction and recovery device 10 can be improved, the efficiency of item recovery can be improved.

[0153] Furthermore, the recovery management server 100 according to this embodiment outputs information indicating the unused state if the unused state continues for a predetermined period (for example, 15 minutes). This prevents the output of non-use information when a temporary non-use state occurs, while allowing the output of non-use information after a predetermined period of non-use has elapsed. Therefore, it is possible to prevent excessive notification of non-use states to the store terminal 20 and the registration and settlement device 30, while suppressing the state in which the volume reduction and recovery device 10 is not operating.

[0154] Furthermore, the collection management server 100 according to this embodiment identifies the reason for non-use based on the collection information and outputs the identified reason for non-use. As a result, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can be notified that the volume reduction and recovery device 10 is powered off or that an error has occurred in the volume reduction and recovery device 10. Therefore, store staff can be encouraged to restore the device from its unused state as soon as possible, thereby reducing the loss of opportunities related to the recovery of goods and thus preventing a decrease in recovery efficiency.

[0155] Furthermore, the recovery management server 100 according to this embodiment extracts events that occurred in the non-use state (such as detection results from the motion sensor or panel operation) based on the recovery information, and outputs information indicating those events. As a result, the store terminal 20, the registration and payment device 30, and the headquarters terminal 120 can present the event to each staff member. Therefore, each staff member can understand the loss of opportunity related to the retrieval of items when they are not in use. In addition, each staff member can estimate the time periods when demand is expected to be high based on the event. Furthermore, by considering the congestion situation during the time periods when high demand is expected (actual data from the registration and payment device 30) and the staff shifts, it is possible to optimize the allocation of staff.

[0156] Furthermore, the collection management server 100 according to this embodiment calculates a contribution value related to environmental conservation based on the amount of collected information included in the collection information and outputs the contribution value. As a result, the store terminal 20, the headquarters terminal 120, and the end-user terminal 130 can display the contribution value. Therefore, stores St and companies using the volume reduction and recovery device 10 can efficiently promote their environmental conservation activities and initiatives. Furthermore, by allowing the conversion target to be selected according to the company's industry, the company's employees, stakeholders, and consumers can easily visualize the amount of reduction, thereby improving the efficiency of item recovery.

[0157] Furthermore, the collection management server 100 according to this embodiment calculates a contribution value based on the cumulative amount of items collected. Therefore, stores and companies that utilize the volume reduction and recovery device 10 can more efficiently promote their environmental conservation activities and initiatives. This allows them to improve their corporate image.

[0158] (Modified examples of the embodiment) Next, we will describe some modifications of the embodiment. In the following modifications, explanations of the contents described in the above-described embodiment will be omitted as appropriate. It is also possible to combine the configurations of the following modifications and embodiments.

[0159] In the embodiment described above, an example was explained in which the recovery management server 100 determines the occurrence of an error and obtains the determination result. An example will now be described in which the volume reduction recovery device 10 determines the occurrence of an error, and the recovery management server 100 obtains the determination result from the volume reduction recovery device 10.

[0160] In the modified example, when an error occurs, the volume reduction and recovery device 10 sends operational data indicating this to the recovery management server 100. This operational data includes the cause of the error (full capacity error or stagnant error) and the time of occurrence. When the device recovers from the error, the volume reduction and recovery device 10 sends operational data indicating this to the recovery management server 100. The recovery management server 100 aggregates the operational data received from the volume reduction and recovery device 10 and sends the aggregated results to other devices such as the headquarters terminal 120.

[0161] Even in this manner, staff at headquarters and stores can understand and analyze the usage and non-use status of the volume reduction and recovery device 10. Therefore, it is possible to prevent a decrease in the item recovery efficiency of the volume reduction and recovery device 10.

[0162] The following is a summary of the embodiments. [Title of Invention] System, Management Device, and Program [Technical Field] The present invention relates to a system, a management device, and a program. [Background technology]

[0163] Conventional volume reduction and collection devices have been known for reducing the volume of items such as empty cans and plastic bottles before collection. For example, there is a known empty bottle collection device that, upon receiving an empty bottle, issues a receipt corresponding to the payment of a return deposit for the collected empty bottle (see, for example, Patent Document 1). [Prior art document] [Patent] [Patent Document 1] Special Publication No. 2000-515801 [Overview of the prefecture] [Problems the invention aims to solve] However, with conventional technology, it was sometimes impossible to monitor or analyze the operation of volume reduction and recovery devices at stores and other locations where such devices were installed. This had the problem of potentially reducing the efficiency of item recovery. This invention has been made in view of these circumstances, and its purpose is to provide a technology that can suppress the decrease in the efficiency of recovering articles.

[0164] [Means for solving the problem] (1) In order to solve the above-mentioned problems, a system according to one aspect of the present invention comprises: an acquisition unit that acquires information relating to recovery from a volume reduction and recovery device that recovers an article by reducing its volume; a determination unit that determines the operating state of the volume reduction and recovery device based on the information relating to recovery acquired by the acquisition unit; and an output unit that outputs information indicating the operating state determined by the determination unit, wherein the determination unit determines, based on the information relating to recovery, whether the article is in a usable state in which it can be recovered or in a non-used state in which it cannot be recovered, and the output unit outputs information indicating the non-used state when the determination unit determines that the article is in a non-used state. With the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can display the operating status of the volume reduction and recovery device 10 under management to each staff member. Therefore, each staff member can understand and analyze the usage and non-use status of the volume reduction and recovery device 10. Consequently, it is possible to prevent a decrease in the efficiency of item recovery by the volume reduction and recovery device 10. In addition, since the period during which the volume reduction and recovery device 10 is not operational (non-use period) can be reduced, the loss of recovery opportunities can be reduced. Furthermore, sales losses associated with the loss of recovery opportunities can also be reduced. Furthermore, with the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can display to each staff member the operating status of the volume reduction and recovery device 10 under management, specifically whether it is in use or not. This allows each staff member to understand and analyze the operating and non-operating status of the volume reduction and recovery device 10. In addition, since the operating rate of the volume reduction and recovery device 10 can be improved, the efficiency of item recovery can be improved. Furthermore, with the above configuration, if a temporary state of non-use occurs, non-use information will not be output, but if the non-use state has elapsed for a predetermined period of time, non-use information can be output. Therefore, it is possible to prevent excessive notification of non-use to the store terminal 20 and the registration and settlement device 30, while suppressing the state in which the volume reduction and recovery device 10 is not operating.

[0165] (2) In the configuration of (1) above, if the discrimination unit determines that the device is in a non-use state, the device may be provided with a storage unit that stores the cause of the non-use state and the events that occurred in the non-use state as information relating to the non-use state, and the output unit may output non-use history information for the volume reduction and recovery device based on the information relating to the non-use state of the volume reduction and recovery device stored in the storage unit. With the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can be notified that the volume reduction and recovery device 10 is powered off or that an error has occurred in the volume reduction and recovery device 10. Therefore, store staff can be encouraged to restore the device from unused status as soon as possible, thereby reducing the loss of opportunities related to the recovery of goods and thus preventing a decrease in recovery efficiency. Furthermore, with the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can present the relevant event to each staff member. As a result, each staff member can understand the loss of opportunity related to the retrieval of items when they are not in use. In addition, each staff member can estimate the time periods when high demand is expected based on the event. Furthermore, by considering the congestion situation during the time periods when high demand is expected (actual data from the registration and settlement device 30) and the staff shifts, it is possible to optimize the allocation of staff.

[0166] (3) In the configuration of (1) or (2) above, the acquisition unit is capable of acquiring information on the recovery from a plurality of volume reduction and recovery devices, and when the discrimination unit determines that the device is in a non-use state, it includes a storage unit that stores the factors causing the non-use state and the events that occurred in the non-use state as information on the non-use state, and the output unit may output non-use history information for the plurality of volume reduction and recovery devices in a comparable manner based on the information on the non-use state of the plurality of volume reduction and recovery devices stored in the storage unit. With the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can compare each store and notify the store if the power to the volume reduction and recovery device 10 is OFF or if an error has occurred in the volume reduction and recovery device 10. Therefore, store staff can be encouraged to quickly restore the device from a non-use state at each store, thereby reducing the loss of opportunities related to the recovery of items at each store and thus preventing a decrease in the recovery efficiency at each store. Furthermore, with the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can compare each store and present the relevant event to each staff member. As a result, each staff member can understand the loss of opportunity related to the retrieval of items when they are not in use, for each store. In addition, each staff member can estimate the time of day when demand is expected to be high, based on the relevant event, for each store. Furthermore, for each store, it is possible to optimize the staffing of each store by considering the congestion situation during the time of day when demand is expected to be high (actual data from the registration and settlement device 30) and the staff shifts.

[0167] In addition, in any of the above configurations, an extraction unit may be provided that extracts events that occurred in the non-use state based on the information regarding the recovery, and the output unit may output information indicating the events extracted by the extraction unit. With the above configuration, the store terminal 20, the registration and payment device 30, and the headquarters terminal 120 can present the relevant event to each staff member. As a result, each staff member can understand the loss of opportunity related to the retrieval of items when they are not in use. Furthermore, each staff member can estimate the time periods when high demand is expected based on the event. In addition, by considering the congestion situation during the time periods when high demand is expected (actual data from the registration and payment device 30) and the staff shifts, it is possible to optimize the allocation of staff.

[0168] In addition, in any of the above configurations, a calculation unit may be provided that calculates a contribution value related to environmental conservation based on the amount of recovery included in the recovery information, and the output unit may output the contribution value calculated by the calculation unit. With the above configuration, the store terminal 20, the headquarters terminal 120, and the end-user terminal 130 can display their contribution values. Therefore, stores St and companies using the volume reduction and recovery device 10 can efficiently promote their environmental conservation activities and initiatives.

[0169] In addition, in the above configuration, the calculation unit may calculate the contribution value based on the cumulative amount of recovered. According to the above configuration, stores St and companies using the volume reduction and recovery device 10 can more efficiently promote their environmental conservation activities and initiatives. Therefore, they can improve their corporate image. In addition, by allowing the conversion target to be selected according to the company's industry, the company's employees, stakeholders, and consumers can easily visualize the amount of reduction, thereby improving the efficiency of item recovery.

[0170] (4) In order to solve the above-mentioned problems, a management device according to one aspect of the present invention comprises: an acquisition unit that acquires information relating to the recovery from a volume reduction and recovery device that recovers an item by reducing its volume; a determination unit that determines the operating state of the volume reduction and recovery device based on the information relating to the recovery acquired by the acquisition unit; and an output unit that outputs information indicating the operating state determined by the determination unit, wherein the determination unit determines, based on the information relating to the recovery, whether the item is in a usable state in which it can be recovered or in a non-used state in which it cannot be recovered, and the output unit outputs information indicating the non-used state when the determination unit determines that the item is in a non-used state. With the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can display the operating status of the volume reduction and recovery device 10 under management to each staff member. Therefore, each staff member can understand and analyze the usage and non-use status of the volume reduction and recovery device 10. Consequently, it is possible to prevent a decrease in the efficiency of item recovery by the volume reduction and recovery device 10. In addition, since the period during which the volume reduction and recovery device 10 is not operational (non-use period) can be reduced, the loss of recovery opportunities can be reduced. Furthermore, sales losses associated with the loss of recovery opportunities can also be reduced.

[0171] (5) In order to solve the above-mentioned problems, a program in another aspect of the present invention is a program in which the computer of a management device functions as an acquisition unit that acquires information on recovery from a volume reduction and recovery device that recovers an item by reducing its volume, a determination unit that determines the operating state of the volume reduction and recovery device based on the information on recovery acquired by the acquisition unit, and an output unit that outputs information indicating the operating state determined by the determination unit, wherein the determination unit determines, based on the information on recovery, whether the item is in a usable state in which it can be recovered or in an unused state in which it cannot be recovered, and the output unit outputs information indicating the unused state when the determination unit determines that the item is in an unused state. With the above configuration, the store terminal 20, the registration and settlement device 30, and the headquarters terminal 120 can display the operating status of the volume reduction and recovery device 10 under management to each staff member. Therefore, each staff member can understand and analyze the usage and non-use status of the volume reduction and recovery device 10. Consequently, it is possible to prevent a decrease in the efficiency of item recovery by the volume reduction and recovery device 10. In addition, since the period during which the volume reduction and recovery device 10 is not operational (non-use period) can be reduced, the loss of recovery opportunities can be reduced. Furthermore, sales losses associated with the loss of recovery opportunities can also be reduced.

[0172] Furthermore, all or part of the functions (input / output, storage, processing (including decision-making)) of the recovery management server 100 described above may be implemented in a device other than the device described as the entity executing those functions.

[0173] Specifically, the above description described a configuration in which the collection management server 100 comprises the following functional units: an acquisition unit 601, a discrimination unit 602, an output unit 603, an extraction unit 604, and a calculation unit 605. All or part of these functional units may be provided in other computer devices. Specifically, for example, all or part of these functional units may be provided in the headquarters terminal 120, the store terminal 20, or other computer devices. Furthermore, the computer devices equipped with these functional units are not limited to multiple units, but may consist of just one unit.

[0174] Specifically, for example, instead of the collection management server 100, the headquarters terminal 120 may perform a process to determine the operating status of the volume reduction and collection device 10 based on the collection information acquired from the volume reduction and collection device 10, and output information indicating the determined operating status.

[0175] Furthermore, the program for implementing the item recovery system 1 and recovery management server 100 described above may be recorded on a computer-readable recording medium, and the program may be loaded into a computer system and executed. Here, "computer system" includes hardware such as the OS and peripheral devices. "Computer-readable recording medium" refers to portable media such as USB (Universal Serial Bus) flash memory, SSD (Solid State Drive), flexible disk, magneto-optical disk, ROM, CD-ROM, and storage devices such as hard disks built into a computer system. Moreover, "computer-readable recording medium" also includes volatile memory (RAM) inside a computer system that acts as a server or client when the program is transmitted via a network such as the Internet or a communication line such as a telephone line, which retains the program for a certain period of time. Furthermore, the above program may be transmitted from the computer system that stores the program in a storage device, etc., to another computer system via a transmission medium or by transmission waves in the transmission medium. Here, "transmission medium" for transmitting the program refers to a medium that has the function of transmitting information, such as a network such as the Internet or a communication line such as a telephone line. Furthermore, the above program may be intended to implement some of the functions described above. It may also be a so-called differential file (differential program) that can implement the aforementioned functions in combination with programs already recorded in the computer system.
