Description

The present invention relates to a settlement device and a program.

Conventionally, there is known a product sales data processing system that includes a registration device where a store clerk registers products and a settlement device where a customer settles the bill. The settlement device is connected to an automatic change dispenser. The automatic change dispenser is used, for example, when the price of products registered in the registration device is settled with cash. The automatic change dispenser may become near-full depending on the customer's usage. The near-full state is a state in which the number of coins that can be stored is close to the allowable limit. When the automatic change dispenser becomes near-full, the settlement device issues a warning to that effect. For example, the settlement device issues a warning by lighting a sign pole provided on the settlement device, displaying a status indicating the state on a screen provided on the settlement device, or displaying a screen indicating the state on a monitor device screen.

Related technology has been disclosed that involves dispensing money of a denomination determined to be overflowing into a storage bag, and displaying information indicating that a storage bag is not installed on an attendant PC (a PC used by store clerks) if the storage bag is not installed (see, for example, Patent Document 1).

JP 2017-162023 A

However, with conventional technology, whenever an automatic change dispenser warning was issued, a store clerk had to go to the settlement device to which the automatic change dispenser was connected and perform the operation to put the settlement device into a paused state, which resulted in a decrease in the work efficiency of the store clerk.

The present invention was made in light of these circumstances, and its purpose is to provide technology that can prevent a decline in the work efficiency of store clerks.

In order to solve the above-mentioned problems, one aspect of the present invention is a settlement device that includes a first storage section for storing coins and a second storage section capable of storing the coins stored in the first storage section , and is capable of changing from a normal state in which settlement processing is possible to a paused state in which settlement processing is impossible when the amount of coins stored in the first storage section becomes equal to or greater than a predetermined amount, and in the paused state , recovers a portion of the coins stored in the first storage section into the second storage section.

In addition, in order to solve the above-mentioned problems, another aspect of the present invention is a program that causes a computer of a settlement device having a first storage section for storing coins and a second storage section capable of storing the coins stored in the first storage section to execute a process that enables the device to change from a normal state in which settlement processing is possible to a suspended state in which settlement processing is impossible when the amount of coins stored in the first storage section becomes equal to or greater than a predetermined amount, and that makes it possible to recover a portion of the coins stored in the first storage section in the suspended state.

(Embodiment 1)
(Network Configuration of POS System 1)
Fig. 1 is an explanatory diagram showing a network configuration of a POS (Point Of Sales) system 1 according to a first embodiment. The POS system 1 is an example of a product sales data processing system. As shown in Fig. 1, the POS system 1 includes a store controller 10, a monitoring device 11, and a plurality of POS registers 20-0 to 20-n. Each device is connected via a LAN (Local Area Network).

The store controller 10 is a computer (e.g., a server) that controls the POS system 1. The store controller 10 stores, for example, a product master. The product master is a file that stores product information such as product identification information (e.g., JAN code), product name, and sales price for each product. The store controller 10 is sometimes referred to as a management device or a higher-level device. The monitoring device 11 is a computer that has a display screen (monitor) and monitors multiple POS registers 20. The monitoring device 11 is sometimes referred to as an assist monitor.

The POS registers 20-0 to 20-n are devices that mainly perform a registration process for registering products to be purchased and a settlement process (also called an accounting process or a settlement process) for settling the price of the registered products. In other words, the POS registers 20-0 to 20-n are devices that mainly combine the functions of a registration device that performs a registration process and a settlement device that performs a settlement process. Details will be described later, but the POS registers 20-0 to 20-n can be set to one of the following modes: a normal mode in which a store clerk and a customer conduct a transaction face-to-face; a settlement-only mode in which the settlement of products registered at other POS registers 20-0 to 20-n is performed; and a full self-service mode in which the customer registers products and makes the settlement themselves.

In this embodiment, the POS register 20-0 functions as a registration device where the store clerk registers products. In other words, the POS register 20-0 is set to normal mode. Below, the POS register 20-0 may be referred to as the "registration device 20R."

The POS registers 20-1 to 20-n also function as settlement devices where customers settle their bills. In other words, the POS registers 20-1 to 20-n are set to a settlement-only mode. Below, the POS registers 20-1 to 20-n may be referred to as "settlement devices 20P1 to 20Pn." When there is no particular distinction between the POS registers 20-1 to 20-n, they may be referred to as "settlement device 20P." When there is no particular distinction between the registration device 20R and the settlement device 20P, the POS registers 20-0 to 20-n may be referred to as "POS register 20."

The POS register 20 is an example of a product sales data processing device. The POS register 20 is a computer device (POS register) that registers products, settles accounts, manages sales data, etc. The store controller 10, the monitoring device 11, and the POS register 20 are connected to each other via a wired or wireless communication, for example, via a LAN (Local Area Network).

(External appearance of POS register 20)
Fig. 2 is an explanatory diagram showing an example of the appearance of the POS register 20. Fig. 2(A) is a perspective view of the POS register 20 as seen from the customer side. Fig. 2(B) is a perspective view of the POS register 20 as seen from the store clerk side. The POS register 20 may be of a type that is placed on a counter or a desk.

2, the POS register 20 includes a customer display unit 201, a customer scanner unit 202, a card payment unit 203, an automatic change dispenser 204, a voice output unit 205, a printing unit 206, a store clerk display unit 207, a key operation unit 208, and a store clerk scanner unit 209. Although not shown, the POS register 20 may also include a sign pole that can be lit in a predetermined manner.

The customer display unit 201 is a display for customers. The customer display unit 201 is, for example, a touch panel. The customer display unit 201 displays various information and accepts various inputs from customers. For example, the customer display unit 201 displays preset keys, which are buttons for selecting products, and accepts operation (pressing) of the preset keys.

The customer-side scanner unit 202 is a scanner unit for customers. The customer-side scanner unit 202 optically reads various information. For example, the customer-side scanner unit 202 optically reads codes (such as barcodes and two-dimensional codes) attached to products. In addition, the customer-side scanner unit 202 can also read codes (such as barcodes and two-dimensional codes) printed on various cards (such as membership cards and point cards).

The card payment unit 203 performs payments using various cards. The various cards referred to here are, for example, credit cards, prepaid cards such as transportation cards, point cards, etc. Furthermore, the various cards may be contact cards (IC cards, magnetic cards) or non-contact cards (IC cards).

The card payment unit 203 includes, for example, a card reading unit, a display unit, and an operation unit. The card reading unit reads information from various cards. If the card is a magnetic card, the card reading unit magnetically reads the information from the card, and if the card is an IC card, the card reading unit electrically reads the information from the card. The display unit of the card payment unit 203 displays various information.

For example, when a credit card is used, the display unit displays the payment amount and a masked PIN number. The operation unit of the card payment unit 203 also accepts various operations from customers or store staff. For example, when a credit card is used, the operation unit accepts a switching operation to use a credit card from a staff member, and also accepts input of a PIN number from the customer.

The automatic change dispenser 204 is a cash settlement unit that performs settlement with cash. The automatic change dispenser 204 has an input port for banknotes and coins, and an output port for banknotes and coins. The input port and output port each have a sensor that detects banknotes and coins, and are positioned facing the customer. The input port accepts cash from customers. The output port outputs change (banknotes and coins). The automatic change dispenser 204 calculates the total amount of cash inserted into the input port, calculates the change amount, which is the difference between the total amount and the purchase amount, and outputs the change and change from the output port.

The audio output unit 205 is a speaker that outputs audio. The audio output unit 205 outputs, for example, audio guidance. The audio guidance is, for example, guidance to assist the customer in registering products or guidance to assist with payment.

The printing unit 206 is a printer device that issues various media such as receipts. The printing unit 206 has an issuing port for issuing receipts. The printing unit 206 is, for example, freely rotatable parallel to the horizontal direction, and the direction of the issuing port can be changed from the store clerk side to the customer side, or from the customer side to the store clerk side. The printing unit 206 may be rotated manually, or may be rotated by the driving force of a motor. Furthermore, if the printing unit 206 is configured to rotate by the driving force of a motor, it may rotate according to the operating mode of the POS register 20, which will be described later.

The clerk display unit 207 is a display for the clerk. The clerk display unit 207 is, for example, a touch panel. The clerk display unit 207 displays various information and accepts various inputs from the clerk. For example, the clerk display unit 207 displays preset keys, which are buttons for selecting products, and accepts the operation (pressing) of the preset keys.

The key operation unit 208 is a hardware key and accepts various inputs from the store clerk. For example, the key operation unit 208 has keys corresponding to products and quantities, and accepts product and quantity selections from the store clerk.

The store clerk scanner unit 209 is a scanner unit for store clerks. The store clerk scanner unit 209 optically reads various types of information. For example, the store clerk scanner unit 209 reads codes. Codes include barcodes and two-dimensional codes. Codes include codes attached to products, codes attached to store clerk nametags, and codes printed on various cards (for example, membership cards, point cards, etc.).

(Hardware configuration of POS register 20)
Next, the hardware configuration of the POS register 20 will be described. Fig. 3 is an explanatory diagram showing an example of the hardware configuration of the POS register 20. In the following, the contents explained in Fig. 2 will be omitted as appropriate. In Fig. 3, the POS register 20 includes a CPU (Central Processing Unit) 301, a ROM (Read Only Memory) 302, a RAM (Random Access Memory) 303, a hard disk 304, a communication unit 305, a customer display unit 201, a customer scanner unit 202, a card settlement unit 203, an automatic change dispenser 204, an audio output unit 205, a printing unit 206, a store clerk display unit 207, a key operation unit 208, and a store clerk scanner unit 209. These can communicate with each other via a bus.

The CPU 301 is a central processing unit that controls the operation of the POS register 20 by reading and executing programs (for example, a product sales data processing program) stored in the ROM 302 .
The ROM 302 is a read-only memory, and stores various types of information used by the CPU 301, including programs.

RAM 303 is a read/write memory that stores various information. For example, RAM 303 stores registration information (registration data) generated in a registration process for registering products, settlement information (settlement data) generated in a settlement process for settling (paying) purchased products, and information obtained from an external device.

The hard disk 304 stores various information. For example, the hard disk 304 may store programs executed by the CPU 301 instead of the ROM 302. The hard disk 304 may also store information generated in various processes and information acquired from the outside instead of the RAM 303.

(Operation mode of POS register 20)
Next, the operation modes of the POS register 20 will be described. The POS register 20 operates in one of a number of operation modes. The operation modes described below are operation modes related to registration and settlement processes during normal business operations, and specifically include a normal mode (face-to-face self-service mode), a checkout-only mode, and a full self-service mode.

The multiple operating modes also include a tallying mode, a maintenance mode, and a training mode. The tallying mode is a mode for tallying and inquiring about sales, inventory, etc. The maintenance mode is a mode in which store clerks and maintenance personnel perform setup and maintenance work. The training mode is a mode in which new store clerks are trained on how to use the POS register 20.

(Regarding normal mode)
The normal mode (face-to-face self-service mode) is an operation mode in which product registration by the clerk is enabled and product registration by the customer is disabled. Specifically, in the normal mode, product registration using the clerk display unit 207, key operation unit 208, and clerk scanner unit 209 is enabled and product registration using the customer display unit 201 and customer scanner unit 202 is disabled. As a result, in the normal mode, it is possible for the clerk to perform the registration process without performing the registration process on the customer side. The POS register 20 set to the normal mode is the registration device 20R.

The normal mode is an operating mode in which the insertion of coins is enabled. Therefore, in the normal mode, it is possible to accept the insertion of coins even while the product registration process is being performed. In the normal mode, the settlement process is performed by inserting coins into the automatic change dispenser 204 and reading a card by the card settlement unit 203. The settlement process is performed after the registration process is performed by the store clerk.

In addition, in normal mode, when the registration process is completed, the POS register 20 (registration device 20R) can also transmit the registration information of the registered product to the POS register 20 (payment settlement device 20P) in the accounting-only mode.

(About accounting-only mode)
The accounting-only mode is an operating mode in which product registration on the clerk side and product registration on the customer side are disabled and settlement is enabled. Specifically, in the accounting-only mode, product registration using the clerk side display unit 207, key operation unit 208, and clerk side scanner unit 209, and product registration using the customer side display unit 201 and customer side scanner unit 202 are disabled. This makes it possible to prevent registration processing from being performed on the clerk side and the customer side in the normal mode. The POS register 20 set in the accounting-only mode is the settlement device 20P.

The accounting-only mode is an operating mode in which the insertion of coins is enabled. In the accounting-only mode, the settlement process is carried out using the registration information transmitted from the registration device 20R. For example, in the accounting-only mode, it is possible to accept the insertion of coins by receiving registration information from the registration device 20R. In the accounting-only mode, the settlement process is carried out by inserting coins into the automatic change dispenser 204 and reading a card by the card settlement unit 203.

(About Full Selfie Mode)
The full self-service mode is an operation mode in which product registration on the customer side is enabled. Specifically, in the full self-service mode, product registration is enabled using the customer side display unit 201 and the customer side scanner unit 202. As a result, in the full self-service mode, the customer side can perform the registration process.

In addition, in the full self-service mode, product registration by the store clerk may also be enabled. Specifically, in the full self-service mode, product registration using the store clerk scanner unit 209, the store clerk display unit 207, and the key operation unit 208 may be enabled. This allows registration processing to be performed on both the store clerk and the customer sides in the full self-service mode. However, in the full self-service mode, product registration by the store clerk may be enabled or disabled by operation of the store clerk.

The full self-service mode is an operating mode in which the insertion of coins is enabled. Therefore, in the full self-service mode, it is possible to accept the insertion of coins even while the product registration process is being carried out. In the full self-service mode, the settlement process is carried out by inserting coins into the automatic change dispenser 204 and reading the card by the card settlement unit 203. The settlement process is carried out after the registration process is carried out by the customer or store clerk.

(Switching between operation modes)
Next, the switching of the operation mode of the POS register 20 will be described. The switching of the operation mode is performed, for example, in response to an explicit mode switching operation by a store clerk to switch the operation mode, or in response to an operation of reading a store clerk code. The switching of the operation mode may also be performed, for example, in response to a time condition. The time condition may be, for example, the passage of a predetermined time since the last operation, or the arrival of a switching time according to a preset schedule. The operation mode may also be switched in response to a mode switching instruction from another device (another POS register 20, a monitoring device, a mobile terminal, etc.). It is assumed that the switching of the operation mode is performed by a store clerk, not by a customer.

(Configuration of the automatic change dispenser)
Fig. 4 is an explanatory diagram showing an example of the configuration of the automatic change dispenser 204. In Fig. 4, the automatic change dispenser 204 includes a first storage unit 401 and a second storage unit 402. The automatic change dispenser 204 also includes an identification unit that identifies denominations, a sorting unit that sorts coins by denomination, and a transport unit that transports coins. The automatic change dispenser 204 also has a function of detecting a near-full state in which the number of coins in the first storage unit 401 is close to the allowable limit that can be stored in the first storage unit 401, and a near-end state in which the number of coins in the first storage unit 401 is low. For example, the automatic change dispenser 204 sets the number of coins that will be in the near-full state and the number of coins that will be in the near-end state for each denomination.

The automatic change dispenser 204 also has a function (mechanism) of moving the coins stored in the first storage section 401 to the second storage section 402. Note that this function is a well-known technology, so a detailed explanation will be omitted.

The automatic change dispenser 204 counts the inserted coins and stores them in the first storage unit 401 under the control of the CPU 301. The automatic change dispenser 204 also counts the coins to be discharged from the first storage unit 401 (for example, coins to be used as change at the time of payment) and discharges them from the discharge outlet. For this reason, the first storage unit 401 stores inserted coins by denomination, such as coins deposited at the time of payment and coins replenished at the time of refilling. The first storage unit 401 is configured so that it cannot be attached or detached from the automatic change dispenser 204. The first storage unit 401 may also be configured so that it can be attached or detached from the automatic change dispenser 204.

The second storage unit 402 is configured to be detachable from the automatic change dispenser 204. When removed from the automatic change dispenser 204, the second storage unit 402 can be carried by a store clerk. The automatic change dispenser 204 is locked in a stored state so that it cannot be carried by anyone without the key. The second storage unit 402 is, for example, box-shaped. The second storage unit 402 may also be bag-shaped.

The second storage unit 402 collects the coins stored in the first storage unit 401. For example, when collecting the coins stored in the first storage unit 401 after the store closes, the automatic change dispenser 204 moves the coins stored in the first storage unit 401 to the second storage unit 402 in response to the operation of a store clerk. The automatic change dispenser 204 can also move the coins in the first storage unit 401 to the second storage unit 402 by denomination.

For example, when a denomination of coins stored in the first storage unit 401 is in a near-full state, the automatic change dispenser 204 can move the coins of that denomination from the first storage unit 401 to the second storage unit 402 in response to an operation by a store clerk. Specifically, the automatic change dispenser 204 counts the coins to be moved from the first storage unit 401 to the second storage unit 402, and moves the coins stored in the first storage unit 401 to the second storage unit 402. The process of moving the coins stored in the first storage unit 401 to the second storage unit 402 is called an "overflow process." Note that the movement of coins from the first storage unit 401 to the second storage unit 402 is not limited to being performed automatically by the automatic change dispenser 204. For example, the coins stored in the first storage unit 401 may be manually moved to the second storage unit 402 by a store clerk.

Next, the management of currency by denomination by the automatic change dispenser 204 will be described. The automatic change dispenser 204 manages the number of remaining coins (number of stored coins) for each denomination according to the control of the CPU 301. Specifically, the automatic change dispenser 204 manages the latest information on the number of remaining coins for each denomination (hereinafter referred to as "remaining change information"). For example, when coins are inserted, the automatic change dispenser 204 updates (adds) the information on the number of remaining coins for each denomination based on the number of coins inserted (number of coins deposited) for each denomination.

In addition, when dispensing currency, the automatic change dispenser 204 updates (subtracts) information regarding the remaining number of coins of each denomination based on the number of coins dispensed (number of coins withdrawn) of each denomination. In addition, when inserting and dispensing currency, the automatic change dispenser 204 stores deposit history information including information such as the number of coins inserted of each denomination, and withdrawal history information including information such as the number of coins dispensed of each denomination.

The number of coins remaining for each denomination, remaining change information, deposit history information, withdrawal history information, etc. may not necessarily be stored in the automatic change dispenser 204, but may be stored in the POS register 20. For example, the POS register 20 may receive the number of coins remaining for each denomination, remaining change information, deposit history information, withdrawal history information, etc. from the automatic change dispenser 204 for each transaction, and store the received information.

The remaining change information, deposit history information, and withdrawal history information may be stored in a memory area provided by the automatic change dispenser 204, or in an external storage device. The external storage device may be, for example, a RAM or hard disk provided in the POS register 20, or may be a storage device provided in a device other than the POS register 20.

(Functions of the POS system 1 according to this embodiment)
Next, functions of the POS system 1 according to this embodiment will be described. The POS system 1 comprises a registration device 20R and a settlement device 20P. The registration device 20R is operated by a store clerk to register products. The settlement device 20P is operated by a customer to settle the products registered by the registration device 20R. The settlement device is connected to an automatic change dispenser 204. The automatic change dispenser 204 comprises a first storage unit 401 and a second storage unit 402.

The settlement device 20P can be in multiple states, including a normal state and a paused state. The normal state is a state in which settlement processing is possible. The normal state includes a waiting state (standby state) in which a customer is not making a settlement, and a state in which a customer is making a settlement.

The pause state is a state in which settlement processing is not possible. The settlement device 20P is in the normal state when the amount of coins stored in the first storage unit 401 is less than a predetermined amount. On the other hand, the settlement device 20P can change from the normal state to the pause state when the amount of coins stored in the first storage unit 401 becomes equal to or greater than the predetermined amount. Specifically, the settlement device 20P can change from the normal state to the pause state when at least one denomination reaches the set number of coins for the near-full state, which is preset for each denomination. When the amount of coins stored in the first storage unit 401 becomes equal to or greater than the predetermined amount, the automatic change dispenser 204 is in the near-full state.

The predetermined amount is not limited to the number set for the near-full state, but may be the number set for the full state. The number set for the full state is the maximum number of coins that can be stored in the first storage unit 401. When the automatic change dispenser 204 is near-full, the settlement device 20P goes into a paused state in response to a store clerk's operation. However, the settlement device 20P may go into a paused state automatically without the need for a store clerk's operation.

When the device is put into a paused state in response to a store clerk's operation, for example, the registration device 20R or the monitoring device 11 displays a confirmation message to the store clerk asking whether or not to put the device into a paused state. To be more specific, when the automatic change dispenser 204 becomes near-full, the settlement device 20P or the monitoring device 11 transmits information to that effect (hereinafter referred to as "near-full information") to the registration device 20R. When the registration device 20R or the monitoring device 11 receives the near-full information, it displays a confirmation button to put the settlement device 20P into a paused state.

When the confirmation button accepts the instruction to put the settlement device 20P into a suspended state, the registration device 20R or the monitoring device 11 sends information indicating that the settlement device 20P is to be put into a suspended state (hereinafter referred to as a "suspended state instruction") to the settlement device 20P. The settlement device 20P goes into a suspended state by receiving the suspended state instruction from the registration device 20R or the monitoring device 11. When the settlement device 20P goes into a suspended state, it sends information indicating that (hereinafter referred to as "suspended state information") to the registration device 20R and the monitoring device 11.

When the settlement device 20P is in a normal state, the registration device 20R can transmit the registration data of the product registered by the registration process to the settlement device 20P. Specifically, the settlement device 20P in the normal state is displayed as a candidate destination on the store clerk side display unit 207 of the registration device 20R. When one of the candidate destinations is selected by the store clerk, the registration device 20R transmits the registration data to the selected settlement device 20P.

On the other hand, when the settlement device 20P is in a suspended state, that is, when the registration device 20R receives suspension information from the settlement device 20P, the registration device 20R prohibits the transmission of registration data to the settlement device 20P. Specifically, the suspended settlement device 20P is not displayed as a candidate destination on the clerk-side display unit 207 of the registration device 20R. For example, a suspended settlement device 20P is displayed as being in a suspended state, and is not selectable as a destination for transmitting registration data. Therefore, if there is a suspended settlement device 20P, the registration device 20R either completes the settlement process on its own device, or transmits the registration data to the settlement device 20P in a normal state.

Even if the POS register 20 is set to full self-service mode, it is still possible to settle the account by receiving registration data from the registration device 20R. Specifically, a POS register 20 set to full self-service mode switches to accounting-only mode by receiving registration data from the registration device 20R. A POS register 20 set to full self-service mode may also go into a suspended state. Even if a POS register 20 set to full self-service mode goes into a suspended state, the registration device 20R prohibits the transmission of registration data to the POS register 20.

Here, it is assumed that the first storage unit 401 will be near full several times during the day. The coins moved to the second storage unit 402 are stored there until closing time. For this reason, the coins stored in the first storage unit 401 may be moved to the second storage unit 402 in small amounts (e.g., 10 to 20 coins) at a time by overflow processing or manually by a store clerk as appropriate. That is, instead of moving all the coins in the first storage unit 401 to the second storage unit 402 at once, a small amount of coins may be moved to the second storage unit 402 so that the time of the pause state is shortened. For example, a small amount of coins may be moved to the second storage unit 402 at the timing when a transaction is completed. This can reduce the time during which the settlement device 20P cannot be used due to the pause state.

For example, the number of coins stored in the first storage section 401 may be a predetermined number expected to be used in one transaction. The predetermined number may be, for example, nine of each of 1 yen, 10 yen, and 100 yen coins, five of each of 5 yen, 50 yen, and 500 yen coins, nine of 1,000 yen bills, and five of 5,000 yen bills, etc. In addition, since the legal upper limit of the number of coins that can be used in one transaction is 20, a number corresponding to this number (for example, 20) may be set as the predetermined number of coins.

(Notification of near-full state)
When the automatic change dispenser 204 becomes near-full, the settlement device 20P or the monitoring device 11 notifies the user that the machine is near-full. The settlement device 20P notifies the user that the machine is near-full by, for example, displaying the display screen of the customer-side display unit 201, by audio from the audio output unit 205, or by lighting up a sign pole (not shown) in a predetermined manner. Note that the notification that the settlement device 20P is near-full is made by the registration device 20R as described below, and does not have to be made by the settlement device 20P.

When the automatic change dispenser 204 becomes near-full, the settlement device 20P or the monitoring device 11 transmits near-full information to the registration device 20R. When the registration device 20R receives the near-full information, it notifies the settlement device 20P that the automatic change dispenser 204 has become near-full. The notification of the near-full state made by the registration device 20R may be, for example, a notification on the display screen of the store clerk display unit 207 or a notification by voice from the voice output unit 205.

(Regarding recovery of currency stored in the first storage unit 401)
When the automatic change dispenser 204 becomes near-full, it performs a recovery process (overflow process) of recovering some of the coins stored in the first storage unit 401 into the second storage unit 402. The automatic change dispenser 204 may perform the overflow process automatically, or in response to an operation by a store clerk.

Here, we will explain the case where overflow processing is performed in response to a store clerk's operation. When the automatic change dispenser 204 becomes near-full, the settlement device 20P displays a selection screen for asking whether or not to perform overflow processing. The selection screen may be displayed on the customer display unit 201, or on the store clerk display unit 207. When the selection screen accepts the start of overflow processing, the settlement device 20P causes the automatic change dispenser 204 to start overflow processing.

Furthermore, if the selection screen does not accept the start of overflow processing, that is, for example, if a selection is received not to start overflow processing, overflow processing will not be started. In this case, the store clerk manually collects the coins stored in the first storage unit 401 into the second storage unit 402 (hereinafter sometimes referred to as "manual collection"). Note that even if the machine becomes near-full, the near-full state may be resolved by paying out more of the denomination that became near-full in the subsequent settlement process.

Here, depending on the structure of the automatic change dispenser 204, overflow processing may take time, and manual collection by a store clerk may be completed more quickly than overflow processing. For this reason, manual collection by a store clerk may take less time to return from a paused state to a normal state. Therefore, depending on the congestion situation (when it is relatively quiet), manual collection by a store clerk may be performed.

This selection screen is not limited to being displayed on the settlement device 20P, but is also displayed on the registration device 20R and the monitoring device 11. Specifically, when the registration device 20R or the monitoring device 11 receives near-full information from the settlement device 20P, it displays a selection screen for asking whether or not to cause the automatic change dispenser 204 of the settlement device 20P to perform overflow processing. In the case of the registration device 20R, the selection screen is displayed on the store clerk display unit 207, and in the case of the monitoring device 11, it is displayed on the monitor.

When the selection screen accepts the start of overflow processing, the registration device 20R or the monitoring device 11 transmits information for starting overflow processing (hereinafter referred to as an "overflow start instruction") to the settlement device 20P. When the settlement device 20P receives the overflow start instruction from the registration device 20R or the monitoring device 11, it causes the automatic change dispenser 204 to start overflow processing.

In addition, if the selection screen displayed on the registration device 20R or the monitoring device 11 does not accept the start of overflow processing, that is, for example, if a selection is accepted not to start overflow processing, an overflow start instruction is not sent. In this case, a store clerk goes to the settlement device 20P and manually collects the bills.

The number of coins to be collected by the second storage unit 402 may be any number that makes the number of coins stored in the first storage unit 401 fall below the set number for the near-full state. Details will be described later using FIG. 11, but a set number for the near-end state, a set number for surplus money, and a set number for the near-end state are set for each denomination. The order of the set numbers, expressed with an inequality sign, is "set number for the near-end state < set number for surplus money < set number for the near-end state." For example, the number of coins to be collected by the second storage unit 402 may be a number that makes the number of coins stored in the first storage unit 401 equal to or greater than the set number for surplus money, but less than the set number for the near-full state.

(About lifting the near-full state)
The settlement device 20P returns from the pause state to the normal state when the near-full state is resolved. The near-full state is resolved when the coins stored in the first storage unit 401 are stored in the second storage unit 402 and the amount of coins stored in the first storage unit 401 falls below a predetermined amount. When the near-full state is resolved, the settlement device 20P may automatically return from the pause state to the normal state, or may display a confirmation button and return from the pause state to the normal state after a store clerk presses the confirmation button. This confirmation button may be displayed on at least one of the settlement device 20P, the registration device 20R, and the monitoring device 11.

When the settlement device 20P returns from the paused state to the normal state, it transmits information indicating that (hereinafter referred to as "return information") to the registration device 20R. When the registration device 20R receives the return information from the settlement device 20P, it lifts the prohibition on sending registration data to the settlement device 20P. In other words, when the settlement device 20P returns to the normal state, the registration device 20R lifts the prohibition on sending registration data.

(Settlement during suspension)
The settlement device 20P is capable of performing a first settlement process including a settlement process using cash, and a second settlement process not including a settlement process using cash. In the first settlement process, a settlement process using cash and a settlement process not including a settlement process using cash can be performed. The second settlement process is a settlement process using a payment method that does not produce change, such as a credit card or electronic money. In the normal state, the settlement device 20P performs the first settlement process. In the paused state, the settlement device 20P disables the first settlement process and enables the second settlement process.

For example, the registration device 20R accepts whether the payment is made using cash or a payment other than cash. If the accepted payment method is a payment method other than cash, the registration data can be transmitted to a settlement device 20P in a dormant state. In other words, the settlement device 20P is displayed as a selectable destination settlement device 20P. Note that the display mode indicating the settlement device 20P may be different from the display modes indicating other settlement devices 20P. For example, the settlement device 20P may be displayed in a conspicuous manner so that it is selected in preference to other settlement devices 20P.

(Example of a screen displayed on the store clerk display unit 207 of the registration device 20R)
Figures 5 and 6 are explanatory diagrams showing examples of screens displayed on the clerk display unit 207 of the registration device 20R. The screens shown in Figures 5 and 6 may be displayed on the monitor of the monitoring device 11, and in this case, may be configured to accept operations by the clerk. In Figures 5 and 6, the clerk display unit 207 displays a payment details area 501, a total points area 502, a payment amount area 503, and a settlement-related information area 504. The customer display unit 201 displays the same contents except for the settlement-related information area 504.

The payment details area 501 displays the product name and price of the purchased item (in the figure, "XX T-shirt" and "XX toothbrush"). The total points area 502 displays the points of the payment, which is shown to be 2 points in the figure. The payment amount area 503 displays the total payment amount. The settlement-related information area 504 displays information related to the settlement device 20P.

In FIG. 5(A), the settlement-related information area 504 displays settlement device information 510 and a confirmation screen 520. The settlement device information 510 includes selection buttons 511 to 513 corresponding to the three settlement devices 20P1, 20P2, and P3.

The selection buttons 511 to 513 include an indication of the status of the corresponding settlement device 20P, and an indication of possible destinations for sending the registration data (the portion displaying "Settlement device P"). For example, the selection button 511 indicates that the first settlement device 20P1 is in a standby state, and is displayed as a possible destination for sending the registration data. The standby state is a normal state in which a customer has not yet made a settlement. When the selection button 511 is pressed, the registration device 20R sends the registration data to the first settlement device 20P1.

The selection button 512 indicates that the second settlement device 20P2 is in a near-full state, and displays candidates for the destination of the registration data. The selection button 512 is enabled for operation. Therefore, when the selection button 512 is pressed, the registration device 20R transmits the registration data to the second settlement device 20P2. Note that the near-full state is a state in which the number of bills is close to the allowable limit that can be stored in the first storage unit 401, but is still usable.

The selection button 513 indicates that the third settlement device 20P3 is offline, and is displayed as unavailable as a candidate destination for sending registration data. The offline state is a state in which the registration device 20R and the third settlement device 20P3 are not connected for communication. The selection button 513 is disabled. Therefore, even if the selection button 513 is pressed, the registration device 20R will not send the registration data to the third settlement device 20P3.

The confirmation screen 520 accepts the selection of whether or not to put the second settlement device 20P2 into a suspended state. Specifically, the confirmation screen 520 displays a button indicating that the second settlement device 20P2 is to be suspended (the "Yes" button) and a button indicating that the second settlement device 20P2 is not to be suspended (the "No" button).

When the "Yes" button is pressed on the confirmation screen 520, the registration device 20R sends an instruction to the second settlement device 20P2 to enter a suspended state, and the second settlement device 20P2 enters a suspended state. When the "No" button is pressed on the confirmation screen 520, the second settlement device 20P2 does not enter a suspended state. When the "Yes" button is pressed on the confirmation screen 520, the screen transitions to the screen shown in FIG. 5 (B).

When the number of bills stored in the first storage unit 401 reaches the allowable limit (when the first storage unit 401 is full), the second settlement device 20P2 goes into a pause state and transmits information (pause information) to that effect. When the registration device 20R receives the pause information, it disables the operation of the selection button 512 corresponding to the second settlement device 20P2.

In FIG. 5(B), the selection button 512 indicates that the second settlement device 20P2 is in an inactive state (in the figure, it displays "Inactive") and is displayed as unavailable for selection as a possible destination for sending registration data. The selection button 512 is invalid. Therefore, even if the selection button 512 is pressed, the registration device 20R will not send the registration data to the second settlement device 20P2.

The selection screen 530 accepts the selection of whether or not to have the automatic change dispenser 204 of the second settlement device 20P2 perform overflow processing. Specifically, the selection screen 530 displays a button indicating that overflow processing should be performed (the "Yes" button) and a button indicating that overflow processing should not be performed (the "No" button). When the "No" button is pressed on the selection screen 530, overflow processing is not performed in the second settlement device 20P2. In this case, manual collection is performed by a store clerk. The selection screen 530 may be displayed when any settlement device 20P is near-full.

In addition, in FIG. 5(B), an estimated time until the overflow process is completed may be displayed. This estimated time may be displayed when a button indicating that the overflow process is to be performed (the "do" button) is pressed, or may be displayed before the "do" button is pressed.

When the "Yes" button is pressed on the selection screen 530, the registration device 20R sends an overflow start instruction to the second settlement device 20P2, and the overflow process is started on the second settlement device 20P2. When the "Yes" button is pressed on the selection screen 530, the screen transitions to the screen shown in FIG. 6 (A).

Figure 6 (A) shows a screen during overflow processing displayed on the store clerk display unit 207 of the registration device 20R. In Figure 6 (A), the selection button 512 indicates that the second settlement device 20P2 is in a suspended state (in the figure, it displays "Overflow processing in progress") and is displayed as unavailable for selection as a possible destination for sending registration data. When the overflow processing is completed and the registration device 20R2 returns from the suspended state to a normal state, the screen transitions to that shown in Figure 6 (B). Note that when "Overflow processing in progress" is displayed in Figure 6 (A), a countdown may be displayed showing the estimated time until the overflow processing is completed.

Figure 6 (B) shows a screen displayed on the store attendant display unit 207 of the registration device 20R when the second settlement device 20P2 returns to a normal state from a suspended state. The registration device 20R displays the screen shown in Figure 6 by receiving recovery information from the second settlement device 20P2. In Figure 6, the selection button 512 indicates that the first settlement device 20P1 is in a standby state, and is displayed as selectable as a candidate destination for sending registration data. Note that the selection button 513 corresponding to the third settlement device 20P3 also indicates that the third settlement device 20P3 is in a standby state, and is displayed as selectable as a candidate destination for sending registration data, when the third settlement device 20P3 goes online.

Note that the selection buttons 511-513 shown in Figures 5 and 6 include, but are not limited to, an indication of candidate destinations for sending registered data (settlement device 20P) and an indication of the status of the settlement device 20P. For example, the selection buttons 511-513 may only include an indication of candidate destinations for sending registered data, and may not include an indication of the status of the settlement device 20P. In this case, the indication of the status of the settlement device 20P may be, for example, a display of the words "Settlement device P1: standby", "Settlement device P2: overflow processing", and "Settlement device P3: offline" in the space in the settlement-related information area 504, i.e., a display in the form of a list.

(Examples of screens displayed on each device)
Fig. 7 is an explanatory diagram showing an example of a screen displayed on each device. Fig. 7(A) is an explanatory diagram showing an example of a screen displayed on settlement device 20P in a paused state. In Fig. 7(A), the customer display unit 201 of settlement device 20P displays that it is in a paused state. Note that the display shown in Fig. 7(A) may be displayed on at least one of customer display unit 201 and clerk display unit 207. In addition, a selection screen 700 is displayed on customer display unit 201 of settlement device 20P.

The selection screen 700 accepts the selection of whether or not to have the automatic change dispenser 204 of the settlement device 20P perform overflow processing. Specifically, the selection screen 700 displays a button indicating that overflow processing should be performed (the "Yes" button) and a button indicating that overflow processing should not be performed (the "No" button). The selection screen 700 is displayed when the settlement device 20P becomes near-full.

When the "Yes" button is pressed on the selection screen 700, the settlement device 20P causes the automatic change dispenser 204 to perform overflow processing. When the "No" button is pressed on the selection screen 700, overflow processing is not performed on the settlement device 20P. In this case, the cashier will manually collect the cash. Note that the selection screen 700 may be displayed when the clerk logs in to prevent customers from operating the selection screen 700.

Figure 7 (B) is an example of a screen displayed on the monitor of the monitoring device 11. The status of each settlement device 20P is displayed on the monitor of the monitoring device 11. Figure 7 (B) shows that the first settlement device 20P1 is in a standby state, the second settlement device 20P2 is in a near-end state, and the third settlement device P3 is in an offline state. When the second settlement device 20P2 is in a near-end state, a warning is displayed to alert the store staff. Note that when the second settlement device 20P2 goes into a paused state or when overflow processing is performed, the monitor of the monitoring device 11 also displays the corresponding information.

(Example of Operation of POS System 1)
Fig. 8 is a sequence diagram showing an example of the operation of the POS system 1. In Fig. 8, when the automatic change dispenser 204 becomes near-full (step S801), the settlement device 20P notifies the fact that it is near-full (step S802). Then, the settlement device 20P transmits near-full information (information indicating that it has become near-full) to the registration device 20R (step S803). The monitoring device 11 manages the remaining change information of each POS register 20. Therefore, the near-full information is not limited to being transmitted from the settlement device 20P to the registration device 20R, but may also be transmitted from the monitoring device 11 to the registration device.

When the registration device 20R receives the near-full information from the settlement device 20P, it notifies the settlement device 20P that it has entered a near-full state (step S804). The registration device 20R then displays a confirmation screen 520 (see FIG. 5(A)) for putting the settlement device 20P into a suspended state (step S805). When the registration device 20R receives a request to put the settlement device 20P into a suspended state on the confirmation screen 520, it transmits a suspension instruction (information indicating that the settlement device 20P is to be put into a suspended state) to the settlement device 20P (step S806).

When the settlement device 20P receives a pause instruction from the registration device 20R, it goes into a pause state (step S807) and transmits pause information (information indicating a pause state) to the registration device 20R (step S808). When the registration device 20R receives pause information from the settlement device 20P, it prohibits transmission of registration data to the settlement device 20P (step S809). Then, the registration device 20R displays a selection screen 530 (see FIG. 5B) for the settlement device 20P to select whether or not to perform overflow processing (step S810). Then, when the registration device 20R accepts the start of overflow processing on the selection screen 530, it transmits an overflow start instruction (information for starting overflow processing) to the settlement device 20P (step S811).

When the settlement device 20P is in the paused state, the settlement device 20P also displays a selection screen 700 (see FIG. 7(A)) for asking whether or not to perform overflow processing (step S812). If the selection screen 700 accepts the start of overflow processing, or if an instruction to start overflow is received from the registration device 20R, the settlement device 20P causes the automatic change dispenser 204 to start overflow processing (step S813). If the selection screen 700 does not accept the start of overflow processing or does not receive an instruction to start overflow, the near-full state is resolved by a store clerk manually collecting the bills (step S813). Note that in the manual collection, the settlement device 20P may be configured to accept the denomination and number of bills specified by the store clerk.

Then, when the near-full state is resolved, the settlement device 20P returns from the paused state to the normal state (step S814). Next, the settlement device 20P transmits recovery information (information indicating that the normal state has been restored from the paused state) to the registration device 20R (step S815), and ends the series of processes. When the registration device 20R receives the recovery information from the settlement device 20P, it lifts the prohibition on transmitting registration data to the settlement device 20P (step S816), and ends the series of processes.

(Example of processing performed by settlement device 20P according to embodiment 1)
Next, an example of a process performed by the settlement device 20P according to the first embodiment will be described with reference to Fig. 9A and Fig. 9B. Fig. 9A and Fig. 9B are flowcharts showing an example of a process performed by the settlement device 20P according to the first embodiment. Note that the process shown in the flowcharts of Fig. 9A and Fig. 9B is constantly (periodically at very short time intervals) started by the settlement device 20P.

In FIG. 9A, the settlement device 20P determines whether the automatic change dispenser 204 is in a near-full state (step S901). If the automatic change dispenser 204 is not in a near-full state or is already in a near-full state (step S901: NO), the settlement device 20P proceeds to step S904.

When the automatic change dispenser 204 is in a near-full state (step S901: YES), the settlement device 20P notifies the automatic change dispenser 204 that it is in a near-full state (step S902). The settlement device 20P then transmits information indicating that the automatic change dispenser 204 is in a near-full state (information indicating that it is in a near-full state) to the registration device 20R (step S903).

The settlement device 20P then determines whether or not a pause instruction has been received from the registration device 20R (step S904). If a pause instruction has not been received (step S904: NO), the settlement device 20P proceeds to step S908. If a pause instruction has been received (step S904: YES), the settlement device 20P enters a paused state (step S905). The settlement device 20P then transmits pause information to the registration device 20R (step S906). Next, the settlement device 20P displays a selection screen for whether or not to perform overflow processing (step S907).

The settlement device 20P then determines whether or not an overflow start instruction has been received from the registration device 20R (step S908). If an overflow start instruction has been received (step S908: YES), the settlement device 20P proceeds to step S910. If an overflow start instruction has not been received (step S908: NO), the settlement device 20P determines whether or not a request to start overflow processing has been accepted on the selection screen for whether or not to perform overflow processing (step S909). If a request to start overflow processing has been accepted (step S909: YES), the settlement device 20P starts overflow processing (step S910).

On the other hand, if the start of overflow processing is not accepted (step S909: NO) and an instruction to start overflow is not received in step S908, the process proceeds to step S911. In this case, depending on the congestion situation, a store clerk will go to a settlement device 20P that is in an inactive state and manually collect the money.

The settlement device 20P then determines whether the near-full state has been resolved (step S911). If the near-full state has not been resolved (step S911: NO), the settlement device 20P ends the series of processes. On the other hand, if the near-full state has been resolved (step S911: YES), the settlement device 20P determines whether the current state is a paused state (step S912). If the current state is not a paused state (step S912: NO), i.e., if the current state is a normal state, the settlement device 20P ends the series of processes.

If the current state of the settlement device 20P is a paused state (step S912: YES), the settlement device 20P returns to a normal state (step S913). Then, the settlement device 20P transmits return information (information indicating that the device has returned to the normal state from the paused state) to the registration device 20R (step S914).

The settlement device 20P then determines whether or not it has received registration data from the registration device 20R (step S915). If the settlement device 20P has not received registration data (step S915: NO), it ends the series of processes. If the settlement device 20P has received registration data (step S915: YES), it determines whether or not it is in a suspended state (step S916). If the settlement device 20P is in a suspended state (step S916: YES), it performs settlement processing (second settlement processing) using a method other than cash (step S917), and ends the series of processes.

If the settlement device 20P is not in a suspended state (step S916: NO), it performs the settlement process (first settlement process) using a method including cash (step S918) and ends the series of processes. Note that a method including cash is a normal payment method including cash, credit card, electronic money, etc. Furthermore, when the settlement device 20P completes the settlement process in step S917 or step S918, it transmits information regarding the settlement process to the registration device 20R, including information indicating that the settlement process has been completed and details of the settlement process (payment method, deposited amount, change, etc.).

(Example of processing performed by the registration device 20R according to the first embodiment)
Next, an example of a process performed by the registration device 20R according to the first embodiment will be described with reference to Fig. 10A and Fig. 10B. Fig. 10A and Fig. 10B are flowcharts showing an example of a process performed by the registration device 20R according to the first embodiment. Note that the process shown in the flowcharts of Fig. 10A and Fig. 10B is constantly (periodically at very short time intervals) started by the registration device 20R.

In FIG. 10, the registration device 20R determines whether or not near-full information has been received from the settlement device 20P (step S1001). If near-full information has not been received from the settlement device 20P (step S1001: NO), the registration device 20R proceeds to step S1004.

When near-full information is received from the settlement device 20P (step S1001: YES), the registration device 20R notifies the settlement device 20P that the automatic change dispenser 204 is in a near-full state (step S1002). The registration device 20R then displays a confirmation screen 520 (see FIG. 5A) for putting the settlement device 20P into a suspended state (step S1003).

Then, the registration device 20R determines whether or not the confirmation button has been used to accept a request to put the registration device 20R into a suspended state (step S1004). If the registration device 20R has not accepted a request to put the registration device 20R into a suspended state (step S1004: NO), the registration device 20R proceeds to step S1006. If the registration device 20R has accepted a request to put the registration device 20R into a suspended state (step S1004: YES), the registration device 20R transmits a suspension instruction (information indicating that the registration device 20R is to be put into a suspended state) to the settlement device 20P (step S1005).

Then, the registration device 20R judges whether or not it has received pause information from the settlement device 20P (step S1006). If the registration device 20R has not received pause information (step S1006: NO), it proceeds to step S1009. If the registration device 20R has received pause information (step S1006: YES), it prohibits the transmission of registration data to the settlement device 20P (step S1007). Then, the registration device 20R displays a selection screen 530 (see FIG. 5(B)) for prompting the settlement device 20P whether or not to perform overflow processing (step S1008). Then, the registration device 20R judges whether or not it has accepted the start of overflow processing on the selection screen (step S1009).

If the registration device 20R does not accept the start of overflow processing (step S1009: NO), the registration device 20R proceeds to step S1011. If the registration device 20R accepts the start of overflow processing (step S1009: YES), the registration device 20R transmits an overflow start instruction (information for starting overflow processing) to the settlement device 20P (step S1010).

Then, the registration device 20R judges whether the registration of the product is completed, for example, by pressing the subtotal key (step S1011). If the registration of the product is not completed (step S1011: NO), the registration device 20R ends the series of processes. If the registration of the product is completed (step S1011: YES), the registration device 20R judges whether there is a settlement device 20P to which the transmission of registration data is prohibited (step S1012). If there is no settlement device 20P to which the transmission of registration data is prohibited (step S1012: NO), the registration device 20R enables the transmission of registration data to the currently connected settlement device 20P, displays candidates for the transmission destination on the store clerk display unit 207 (step S1013), and proceeds to step S1017.

On the other hand, if there is a settlement device 20P for which the transmission of registration data is prohibited (step S1012: YES), the registration device 20R judges whether the customer will pay in cash at the time of settlement (step S1014). When making the judgment in step S1014, the registration device 20R displays a screen that accepts the customer's payment method. This screen is a selection screen that accepts the selection of whether to pay in cash or to pay by credit card or IC card without change. The selection screen is displayed on the customer side display unit 201, and may be a screen that can accept operations from the customer. By accepting operations from the selection screen, the registration device 20R judges whether the customer will pay in cash at the time of settlement.

If the payment is in cash (step S1014: YES), the registration device 20R disables the transmission of registration data to the inactive settlement device 20P, displays candidate destinations (step S1015), and proceeds to step S1017. If the payment is not in cash (step S1014: NO), the registration device 20R enables the transmission of registration data to the inactive settlement device 20P, and displays candidate destinations (step S1016). The registration device 20R then determines whether a destination has been selected from the displayed candidates (step S1017). If a destination has not been selected from the displayed candidates (step S1017: NO), the registration device 20R proceeds to step S1019.

When a destination is selected from the displayed candidates (step S1017: YES), the registration device 20R transmits the registration data to the selected settlement device 20P (step S1018). The registration device 20R then determines whether or not recovery information (information indicating that the normal state has been restored from a suspended state) has been received from the settlement device 20P (step S1019). When recovery information has not been received (step S1019: NO), the registration device 20R ends the series of processes. When recovery information has been received (step S1019: YES), the prohibition on transmission of the registration data to the settlement device 20P is lifted (step S1020), and the series of processes ends.

In the first embodiment described above, when the amount of coins stored in the first storage unit 401 is equal to or greater than a predetermined amount, the settlement device 20P can be put into a suspended state, and when the settlement device 20P is in a suspended state, the registration device 20R is prohibited from sending product registration data. As a result, when the automatic change dispenser 204 of the settlement device 20P is near full, the settlement device 20P can be put into a suspended state, and settlement cannot be performed with the suspended settlement device 20P. Therefore, even if the settlement device 20P is near full, it is possible to intentionally leave the settlement device 20P alone for a while. This allows the store clerk to perform the work to release the suspended state when he or she has free time, and prevents the store clerk from being hindered in registering products. Therefore, it is possible to prevent a decrease in the store clerk's work efficiency.

In addition, in the first embodiment, when the coins stored in the first storage unit 401 are stored in the second storage unit 402 and fall below a predetermined amount, the settlement device 20P returns from the paused state to the normal state, and the registration device 20R cancels the prohibition on sending registration data. Therefore, when the full state is resolved, settlement can be performed at the settlement device 20P.

In addition, in the first embodiment, the automatic change dispenser 204 is configured to perform a recovery process (overflow process) in which a portion of the coins stored in the first storage unit 401 is recovered into the second storage unit 402 when the amount of coins stored in the first storage unit 401 reaches or exceeds a predetermined amount. This makes it possible to resolve the near-full state without the need for a store clerk to manually recover the coins. This therefore reduces the workload of the store clerk when returning the settlement device 20P from a paused state to a normal state.

In addition, in the first embodiment, the settlement device 20P is configured to receive from the store clerk a choice of whether or not to have the automatic change dispenser 204 perform a collection process. As a result, depending on the structure of the automatic change dispenser 204, manual collection by a store clerk may take less time to resolve the near-full state than overflow processing, but in such cases, when the machine is relatively empty, it is more efficient to have the store clerk collect the changes manually. Therefore, the near-full state can be resolved efficiently.

In addition, in the first embodiment, when the registration device 20R receives a selection from a store clerk to perform collection processing, information indicating that is sent to the settlement device 20P. This allows the settlement device 20P to perform collection processing in response to an instruction from the registration device 20R. Therefore, the near-full state can be resolved without the store clerk having to go to the settlement device 20P. This reduces the work load on the store clerk.

In addition, in the first embodiment, the settlement device 20P, in the paused state, disables the first settlement process, which includes the settlement process using cash, and enables the second settlement process, which does not include the settlement process using cash. This allows the settlement device 20P in the paused state to be used as a settlement device 20P dedicated to cashless payments, thereby improving settlement efficiency.

In addition, in the first embodiment, the settlement device 20P is configured to switch from a normal state to a suspended state in response to an operation by a store clerk when the amount of coins stored in the first storage section 401 reaches or exceeds a predetermined amount. As a result, even if the automatic change dispenser 204 of the settlement device 20P becomes near-full, for example, it can be switched to a suspended state at the discretion of the store clerk, since it can still be used in a near-full state. This can therefore improve the convenience of the settlement device 20P.

(Modification of the first embodiment)
A modified example of the first embodiment will be described below. In the first embodiment described above, when the amount of coins stored in the first storage unit 401 becomes equal to or exceeds a predetermined amount, the state is changed from the normal state to the pause state in response to an operation by a store clerk. In a modified example of the first embodiment, in addition to or instead of such a configuration, when the amount of coins stored in the first storage unit 401 becomes equal to or exceeds a predetermined amount, the state may be changed from the normal state to the pause state automatically. Here, the settlement device 20P can change from the normal state to the pause state when the amount of coins stored in the first storage unit 401 becomes equal to or exceeds a predetermined amount. When this predetermined amount is set as the "set number for the full state," the settlement device 20P may automatically go to the pause state when the automatic change dispenser 204 becomes full.

The predetermined amount may include a first predetermined amount (e.g., the set number of coins in a near-full state) and a second predetermined amount (e.g., the set number of coins in a full state). In this case, the settlement device 20P may enter a paused state in response to an operation by a store clerk when the amount of coins stored in the first storage unit 401 becomes equal to or greater than the first predetermined amount. The settlement device 20P may also automatically enter a paused state from the normal state when the amount of coins stored in the first storage unit 401 becomes equal to or greater than the second predetermined amount.

With this configuration, the settlement device 20P can automatically enter a paused state when the amount of coins stored in the first storage section 401 reaches or exceeds a predetermined amount. This reduces the number of times the store clerk must check or operate the device, thereby reducing the workload of the store clerk.

(Embodiment 2)
A second embodiment will be described below. In the second embodiment, the contents described in the first embodiment are given the same reference numerals, and the description will be omitted as appropriate. In the first embodiment described above, when the settlement device 20P is in a suspended state, the registration device 20R is simply prohibited from transmitting registration data. In the second embodiment, in addition to or instead of such a configuration, a configuration will be described in which surplus money from a POS register 20 that is in a near-full state is deposited into another POS register 20 that is in a near-end state.

(Functional Configuration of POS System 1 of Second Embodiment)
First, a functional configuration of the POS system 1 according to the second embodiment will be described. The POS system 1 according to the second embodiment includes one or more registration devices 20R, a plurality of settlement devices 20P, and a plurality of automatic change dispensers 204 connected to the plurality of settlement devices 20P, respectively. The plurality of automatic change dispensers 204 include a first automatic change dispenser 204 and a second automatic change dispenser 204.

The first automatic change dispenser 204 is an automatic change dispenser 204 that can dispense currency, for example, an automatic change dispenser 204 in a near-full state. The second automatic change dispenser 204 is an automatic change dispenser 204 that can deposit currency, for example, an automatic change dispenser 204 in a near-end state. Note that the second automatic change dispenser 204 is not limited to an automatic change dispenser 204 in a near-end state, but may also be an automatic change dispenser 204 in which the denomination of the deposit has not reached the set number of surplus currency coins.

Here, the monitoring device 11 acquires information about the currency of the first automatic change dispenser 204 and the second automatic change dispenser 204. The information about the currency is, specifically, information for depositing currency from the first automatic change dispenser 204 to the second automatic change dispenser 204. For example, the information about the currency includes information about a denomination that has reached a near-end state in the second automatic change dispenser 204, information about the number of coins of that denomination that are in short supply, information identifying the second automatic change dispenser 204, and the like. The information about the currency also includes information about a denomination that has reached a near-full state in the first automatic change dispenser 204, information about the number of coins of that denomination that are in surplus, information identifying the first automatic change dispenser 204, and the like.

The information about currency is generated based on the number of coins remaining for each denomination, the remaining change information, the deposit history information, and the withdrawal history information of the multiple automatic change dispensers 204. The information about currency is generated, for example, by the monitoring device 11. Note that the information about currency may be generated by any one of the multiple POS registers 20.

Based on information about the currency, the POS register 20 performs control (hereinafter referred to as "recovery control") to recover some of the currency in the first storage unit 401 of the first automatic change dispenser 204 to the second storage unit 402 of the first automatic change dispenser 204. The recovery control is a control for making up for the shortage of a denomination in the second automatic change dispenser 204 from the surplus currency in the first automatic change dispenser 204.

Specifically, collection control involves carrying out the following controls. For example, for that denomination, it may perform an overflow process for the number of coins to be replenished in a POS register 20 that is near-full, and it may give various notifications (notifications that prompt the user to select whether or not to perform overflow processing, notifications that overflow processing will be performed automatically, notifications that prompt store staff to perform manual collection, notifications that specify a POS register 20 that is near-end, notifications of the number of coins to be replenished in a POS register 20 that is near-end, etc.).

Overflow processing in collection control may be performed automatically by the POS register 20 that has reached a near-full state. Various notifications in collection control are given by the POS register 20 through display and sound. By giving such notifications, coins collected in the second storage section 402 of the POS register 20 that has reached a near-full state can be moved to the first storage section 401 of the POS register 20 that has reached a near-end state.

(Regarding the number of coins set)
Next, the set number of coins managed by the automatic change dispenser 204 will be described with reference to Fig. 11. Fig. 11 is an explanatory diagram showing an example of the set number for each denomination. A setting table 1100 in Fig. 11 shows the set number for the near-end state, the set number of surplus coins, and the set number for the near-full state for each denomination in the first storage unit 401.

The set number for the near-end state is the number at which the POS register 20 recognizes that the change is in a near-end state. The set number of surplus coins is the number that can be moved to the automatic change dispenser 204 of another POS register 20. The set number for the near-full state is the number at which the POS register 20 recognizes that the change is in a near-full state. The information shown in FIG. 11 is stored in a location that can be referenced by the monitoring device 11. Note that the monitoring device 11 may store the information shown in FIG. 11 within its own device.

(An example of the number of coins currently held by each denomination in each POS register 20)
Fig. 12 is an explanatory diagram showing an example of the currently held number of coins for each denomination for each POS register 20. Fig. 12 (A) shows the currently held number of coins in a first automatic change dispenser 204 connected to a certain POS register 20 (e.g., a first settlement device 20P1). Fig. 12 (B) shows the currently held number of coins in a second automatic change dispenser 204 connected to a certain POS register 20 (e.g., a second settlement device 20P2). Fig. 12 (C) shows the currently held number of coins in an automatic change dispenser 204 connected to a certain POS register 20 (another settlement device 20Pn).

As shown in FIG. 12(A), the automatic change dispenser 204 of the first settlement device 20P1 is in a near-full state for 50 yen. Also, as shown in FIG. 12(B), the automatic change dispenser 204 of the second settlement device 20P2 is in a near-end state for 50 yen. Also, as shown in FIG. 12(C), the automatic change dispenser 204 of the nth settlement device 20P is in a normal state (neither near-full nor near-end state) for all denominations.

In the current number of coins held as shown in FIG. 12, to eliminate the near-full state of the automatic change dispenser 204 of the first settlement device 20P1, the coins stored in the first storage unit 401 can be collected into the second storage unit 402. To eliminate the near-end state of the automatic change dispenser 204 of the second settlement device 20P2, the coin (50 yen) collected in the second storage unit 402 of the first settlement device 20P1 can be moved to the first storage unit 401 of the second settlement device 20P2.

To be more specific, for example, the number of 50 yen bills at the first settlement device 20P1 is 202 bills, which is 62 bills more than the surplus set number (120 bills). The number of 50 yen bills at the second settlement device 20P2 is 48 bills, which is 2 bills less than the near-end set number (50 bills). Therefore, by transferring a predetermined number of bills (for example, 62 bills) from the first settlement device 20P1 to the second settlement device 20P2, it is possible to resolve the near-full state at the first settlement device 20P1 and the near-end state at the second settlement device 20P2.

The information shown in Figures 12 (A) to (C) is stored in a location that can be referenced by the monitoring device 11. For example, the monitoring device 11 may store the information shown in Figures 12 (A) to (C) within its own device. For example, the monitoring device 11 may make a request (request for remaining change information) to each POS register 20 on the LAN, receive information on the number of coins held by denomination (remaining change information) from each POS register 20 on the LAN, and store the information within its own device. Also, each POS register 20 on the LAN may transmit the remaining change information to the monitoring device 11 when the number of coins held by denomination changes.

Each POS register 20 transmits transaction information to the store controller 10. Therefore, the store controller 10 can obtain the remaining change information of each POS register 20 based on the transaction information. Therefore, the monitoring device 11 may receive the remaining change information of each settlement machine from the store controller 10, rather than receiving the remaining change information from each POS register 20 individually.

When a POS register 20 (first settlement device 20P1) is in a near-full state, the monitoring device 11 selects a POS register 20 to be replenished. The POS register 20 to be replenished is, for example, the POS register 20 (second settlement device 20P2) that is in a near-end state.

The POS register 20 to be replenished may be selected by the store clerk. In this case, for example, the POS register 20 (registration device 20R or settlement device 20P) may receive information from the monitoring device 11 indicating the first settlement device 20P1 from which the replenishment amount can be dispensed. The POS register 20 (registration device 20R or settlement device 20P) may then display the first settlement device 20P1 from which the replenishment amount can be dispensed to the store clerk as a candidate from which the replenishment amount can be obtained, and may accept from the store clerk the first settlement device 20P1 from which the replenishment amount can be obtained.

Note that the monitoring device 11 is not limited to managing the number of coins in each POS register 20 (each automatic change dispenser 204). For example, the monitoring device 11 may manage the number of coins in any POS register 20 or in a POS register 20 written by the store controller 10.

(Example of a screen displayed on the store clerk display unit 207 of the registration device 20R)
FIG. 13 is an explanatory diagram showing an example of a screen displayed on the clerk-side display unit 207 of the registration device 20R. The screen shown in FIG. 13 may be displayed on the monitor of the monitoring device 11, and in this case, the monitoring device 11 may receive the operation of the clerk. In FIG. 13, the clerk-side display unit 207 displays the current number of coins held by the first settlement device 20P1 and the current number of coins held by the second settlement device 20P2. Among the current number of coins held by the first settlement device 20P1, the denomination (50 yen) that is in a near-full state is displayed in a display mode different from that of the other denominations. In addition, among the current number of coins held by the second settlement device 20P2, the denomination (50 yen) that is in a near-end state is displayed in a display mode different from that of the other denominations.

The selection screen 1300 includes a number selection button 1301 and a decision button 1302. The number selection button 1301 accepts a change in the number of coins to be moved from the first settlement device 20P1 to the second settlement device 20P2. In the figure, it is shown that 62 coins of 50 yen denomination are to be moved. The number selection button 1301 includes a "+" button that accepts an addition to the number of coins, and a "-" button that accepts a subtraction to the number of coins. Note that in FIG. 13, the set number of coins in the near-end state, the set number of coins in the surplus money state, and the set number of coins in the near-full state may also be displayed.

The decision button 1302 accepts the selection of whether or not to have the automatic change dispenser 204 of the first settlement device 20P1 perform overflow processing. Specifically, the decision button 1302 displays a button indicating that overflow processing is to be performed (the "Yes" button) and a button indicating that overflow processing is not to be performed (the "No" button). When the "No" button of the decision buttons 1302 is pressed, overflow processing is not performed in the first settlement device 20P1. In this case, manual collection is performed by a store clerk. The selection screen 1300 may be displayed when any settlement device 20P becomes near-full.

In addition, in FIG. 13, a register selection button 1310 and a replenishment button 1320 are displayed on the store clerk display unit 207. When the register selection button 1310 is pressed, the number of coins currently held in other POS registers 20, other possible sources for obtaining replenishment money, other possible sources for replenishment money, etc. are displayed in a selectable manner. When the replenishment button 1320 is pressed, it is determined that replenishment will not be performed between POS registers 20, but will be performed separately.

(One example of the operation of the POS system 1 according to the second embodiment)
Fig. 14 is a sequence diagram showing an example of the operation of the POS system 1 according to the second embodiment. Fig. 14 illustrates an example of the operation of the first settlement device 20P1 (near-full state), the registration device 20R, the monitoring device 11, and the second settlement device 20P2 (near-end state).

In FIG. 14, when the automatic change dispenser 204 becomes near-full (step S1401), the first settlement device 20P1 notifies the user that the automatic change dispenser 204 is near-full (step S1402). The first settlement device 20P1 then transmits near-full information (information indicating that the automatic change dispenser 204 is near-full) to the registration device 20R (step S1403).

The monitoring device 11 manages the remaining change information for each POS register 20. Therefore, the near-full information may be sent from the monitoring device 11 to the registration device, not necessarily from the settlement device 20P to the registration device 20R.

When the registration device 20R receives the near-full information from the first settlement device 20P1, it notifies the first settlement device 20P1 that it has entered a near-full state (step S1404). The registration device 20R then displays a confirmation screen 520 (see FIG. 5A) for putting the first settlement device 20P1 into a suspended state (step S1405). When the registration device 20R receives a request to put the first settlement device 20P1 into a suspended state on the confirmation screen 520, it transmits a suspension instruction (information indicating that the first settlement device 20P1 is to be put into a suspended state) to the first settlement device 20P1 (step S1406).

When the first settlement device 20P1 receives the pause instruction from the registration device 20R, it goes into a pause state (step S1407) and transmits pause information (information indicating the pause state) to the registration device 20R (step S1408). When the registration device 20R receives the pause information from the first settlement device 20P1, it prohibits the transmission of registration data to the first settlement device 20P1 (step S1409).

The monitoring device 11 detects a settlement device 20P (first settlement device 20P1) that is in a near-full state (step S1410). The detection of a settlement device 20P that is in a near-full state is performed based on remaining change information, etc. However, this is not limited to this, and a settlement device 20P that is in a near-full state may be detected by receiving near-full information from the first settlement device 20P1.

Then, the monitoring device 11 requests the remaining change information from the multiple settlement devices 20P, including the second settlement device 20P2 (step S1411). Note that since the monitoring device 11 constantly manages the remaining change information of each settlement device 20P, if the monitoring device 11 has obtained the latest remaining change information, it does not need to request the remaining change information from the multiple settlement devices 20P, including P (in the figure, the second settlement device 20P2) at the timing of step S1411.

When the second settlement device 20P2 receives the request for remaining change information, it acquires the remaining change information of the automatic change dispenser 204 (step S1413). The second settlement device 20P2 then transmits the acquired remaining change information to the monitoring device 11 (step S1414). The monitoring device 11 then generates information about the currency of the first settlement device 20P1 (first automatic change dispenser 204) and the second settlement device 20P2 (second automatic change dispenser 204) and transmits it to the registration device 20R (step S1415).

When the registration device 20R receives information about the currency from the monitoring device 11, it performs collection control. For example, the registration device 20R displays the denomination and number of coins that are in short supply at the second settlement device 20P2 on the store clerk display unit 207 (step S1416). This allows the store clerk to understand that the second settlement device 20P2 is in a near-end state. Note that if there is no settlement device 20P that is in a near-end state, the registration device 20R can simply notify that fact.

Then, if the denomination that is in the near-end state at the second settlement device 20P2 is the same as the denomination that is in the near-full state at the first settlement device 20P1, the registration device 20R sends a withdrawal instruction to the first settlement device 20P1 (step S1417).

When the first settlement device 20P1 receives a withdrawal instruction, it displays an overflow processing selection screen and a message encouraging withdrawal (for the second settlement device 20P2 that is near-end and the shortfall in the second settlement device 20P2) (step S1418). The screen and display in step S1418 are, for example, a screen equivalent to the selection screen 1300 shown in FIG. 13.

The screen and display in step S1418 may be displayed by a store clerk logging in. The display in step S1418 allows the store clerk who visits the first settlement device 20P1 to start overflow processing and to understand the second settlement device 20P2 that is near-end and the shortfall in the second settlement device 20P2. If there is no settlement device 20P that is near-end, the first settlement device 20P1 may not display the overflow processing selection screen 700.

The registration device 20R also displays a selection screen 1300 (see FIG. 13) for prompting the first settlement device 20P1 as to whether or not to perform overflow processing (step S1419). When the registration device 20R accepts the start of overflow processing on the selection screen 1300, it transmits an overflow start instruction (information for starting overflow processing) with the contents set on the selection screen 1300 to the first settlement device 20P1 (step S1420).

When the first settlement device 20P1 accepts the start of overflow processing on the selection screen 700 (see FIG. 7(A)) for whether or not to perform overflow processing, or receives an instruction to start overflow from the registration device 20R, it causes the automatic change dispenser 204 to start overflow processing (step S1421). When the first settlement device 20P1 does not accept the start of overflow processing on the selection screen or does not receive an instruction to start overflow, it causes the near-full state to be resolved by manual collection by a store clerk (step S1421). When manually collecting, the first settlement device 20P1 may be configured to accept the denomination and number of coins specified by the store clerk.

Then, when the near-full state is resolved, the first settlement device 20P1 returns from the paused state to the normal state (step S1422). Next, the first settlement device 20P1 transmits recovery information (information indicating that the normal state has been restored from the paused state) to the registration device 20R (step S1423). Upon receiving the recovery information from the first settlement device 20P1, the registration device 20R lifts the prohibition on transmitting registration data to the first settlement device 20P1 (step S1424), and ends the series of processes.

The first settlement device 20P1 also stores withdrawal information indicating the denomination and number of coins collected by the overflow process or manual collection (step S1425). The first settlement device 20P1 then transmits the withdrawal information to the monitoring device 11 (step S1426), and ends the series of processes.

When the monitoring device 11 receives the withdrawal information from the first settlement device 20P1, it transmits a deposit acceptance instruction to the second settlement device 20P2 (step S1427). Then, the monitoring device 11 stores the withdrawal history information of the first settlement device 20P1 (step S1428).

When the second settlement device 20P2 receives a deposit acceptance instruction from the monitoring device 11, it accepts the deposit (step S1429). The second settlement device 20P2 then transmits deposit information indicating the denomination and number of coins deposited to the monitoring device 11 (step S1430), and ends the series of processes. When the monitoring device 11 receives the deposit information from the first settlement device 20P1, it stores the deposit history information of the second settlement device 20P2 (step S1431), and ends the series of processes.

In the second embodiment described above, based on information about the currency in a certain POS register 20 (first automatic change dispenser 204) and another POS register 20 (second automatic change dispenser 204), control is performed to recover some of the currency in the first storage unit 401 of the first automatic change dispenser 204 to the second storage unit 402 of the first automatic change dispenser 204. This makes it possible to efficiently move currency in the first automatic change dispenser 204 that is near full, for example, to the second automatic change dispenser 204 that is near end. This reduces the burden on store clerks involved in depositing and dispensing currency in the POS system 1.
