Description

The present invention relates to a product sales data processing system and a program.

Conventionally, fast food restaurants, family restaurants, and other eateries use a system in which orders are received from customers using a POS (Point Of Sales) terminal device or an order terminal device carried by a staff member, and the received order details are sent to a kitchen printer device. The kitchen printer device is placed in the kitchen and issues an instruction slip showing cooking instructions. For example, the product, quantity, and seat number are printed on the instruction slip. When the instruction slip is issued, the kitchen staff member begins cooking the order details indicated on the instruction slip. Then, when the cooking is completed, the instruction slip is handed over to a hall staff member together with the cooked food. The hall staff member serves the cooked food to the table with the seat number printed on the instruction slip.

During business hours, a kitchen printer may run out of paper and be unable to print order slips. To address this issue, there is a known order entry device that, when a kitchen printer detects that it is out of paper, sends order information to another kitchen printer other than the one that is out of paper and has it print the order (see, for example, Patent Document 1 below).

JP 2001-150762 A

However, in conventional technology, for example, if a kitchen printer device is unable to output cooking instructions due to a malfunction or other reason, outputting cooking instructions on a POS terminal device may hinder the operation of the POS terminal device's operator, or the output cooking instructions may be difficult for store staff to understand, depending on the state of the POS terminal device. For this reason, conventional technology has the problem of being unable to output cooking instructions appropriately.

The present invention was made in consideration of these circumstances, and its purpose is to provide a technology that can output cooking instructions appropriately.

In order to solve the above-mentioned problems, a product sales data processing device, which is one aspect of the present invention, is a product sales data processing system including a cooking instruction output device that outputs cooking instructions for ordered products, and a payment device that settles the payment for the products and outputs a payment slip indicating the payment details, characterized in that the payment device is equipped with a discrimination means that discriminates the state of the payment device when the cooking instruction output device is unable to output the cooking instructions, and an output control means that causes the payment device to output the cooking instructions based on the result of the discrimination of the state by the discrimination means.

(Embodiment)
FIG. 1 is an explanatory diagram showing an example of a network configuration of a POS (Point Of Sales) system according to an embodiment of the present invention. The POS system 1 shown in FIG. 1 includes a management device 10, a POS terminal device 20, an order terminal device 30, a kitchen printer device 40, and a kitchen monitor 50. Each device is connected to be able to communicate with each other via a LAN 60. Although FIG. 1 shows one of each device, there may be multiple devices. In the following description, each device is assumed to be able to communicate with each other directly, but they may also communicate with each other via the management device 10.

The POS system 1 can be introduced in restaurants such as family restaurants. Staff working at the restaurant include wait staff who serve customers and kitchen staff who cook.

The management device 10 manages each device. For example, the management device 10 can display the status of each device (operation mode, processing status, etc.) and control each device. The management device 10 also manages various information. The various information includes, for example, order information sent from the order terminal device 30, settlement information sent from the POS terminal device 20, and instruction slip information sent from the kitchen printer device 40. For example, a desktop computer, a tablet terminal, a laptop computer, etc. can be used as the management device 10.

The POS terminal device 20 is a register that mainly handles the settlement of merchandise. The POS terminal device 20 can also register merchandise. When settlement is carried out, the POS terminal device 20 receives input of the transaction items to be settled by a store clerk, and the payment procedure is carried out by a customer. The POS terminal device 20 also manages the order details (registered merchandise information) accepted by the order terminal device 30, settlement information settled by the POS terminal device 20, and the like.

The order terminal 30 is a portable terminal carried by a waiter. For example, the waiter accepts orders from customers and inputs the accepted details into the order terminal 30. Once the order is confirmed, the order terminal 30 transmits the order details to the kitchen printer 40. The order terminal 30 also transmits the accepted order details to the POS terminal 20. In this way, the POS terminal 20 manages the order details accepted by the order terminal 30.

The kitchen printer device 40 is placed in the kitchen and issues instruction slips showing cooking instructions. For example, the product, quantity, seat number, etc. are printed on the instruction slip. When the instruction slip is issued, the kitchen staff begins cooking the order indicated on the instruction slip. Then, when the cooking is completed, the instruction slip is handed over to the hall staff along with the cooked food. The hall staff serves the cooked food to the table with the seat number printed on the instruction slip.

The kitchen monitor 50 is, for example, a display placed in the kitchen. The kitchen monitor 50 is capable of displaying information corresponding to cooking instructions (hereinafter referred to as "cooking instruction information"). The cooking instruction information includes, for example, the product, the quantity, the seat number, and the like. When the cooking instruction information is displayed, the kitchen staff can check the displayed content and start cooking the order content indicated by the cooking instruction information.

The POS system 1 may also include a store controller and a monitoring terminal. The store controller is a computer device that manages the order details accepted by the order terminal 30 and the settlement information settled by the POS terminal 20, as well as various information such as product inventory status, sales history, deposit and withdrawal records, and member information. The monitoring terminal is a monitoring monitor that is placed to monitor the POS terminal 20 when a customer uses the POS terminal 20 for self-use.

(Example of configuration of POS terminal device 20)
Next, the configuration of the POS terminal 20 will be described with reference to FIGS.
2A and 2B are diagrams showing the external appearance of the POS terminal 20. Fig. 2A is a perspective view of the POS terminal 20 as seen from the store clerk's side, and Fig. 2B is a perspective view of the POS terminal 20 as seen from the customer's side.
Fig. 3 is a diagram showing an example of the hardware configuration of the POS terminal 20. In Fig. 2 and Fig. 3, the same components are denoted by the same reference numerals.

Below, the components of the POS terminal device 20 shown in FIG. 3 will be described with reference to FIG. 2. The POS terminal device 20 comprises a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, a hard disk 204, a customer display unit 205, a customer scanner unit 206, a card payment unit 208, a change dispenser 209, a store clerk display unit 210, a store clerk scanner unit 212, a printing unit 213, an audio output unit 214, a communication unit 215, and a camera 216. These can communicate with each other via a bus.

The CPU 201 is a central processing unit that reads and executes various programs stored in the ROM 202 to control the operation of the POS terminal 20. The various programs include a product sales data processing program according to this embodiment.
The ROM 202 is a read-only memory, and stores various types of information used by the CPU 201, including programs.

RAM 203 is a readable and writable memory that stores various information. For example, RAM 203 stores information acquired from the outside and information generated during processing. This information includes, for example, registration information generated during a registration process that registers ordered products, and settlement information generated during a settlement process that settles for registered products.

The hard disk 204 stores various information. For example, the hard disk 204 stores the image captured by the camera 216 (e.g., video). For example, the hard disk 204 may store various programs, such as a product sales data processing program executed by the CPU 201, instead of the ROM 202. Also, instead of the RAM 203, the hard disk 204 may store information acquired from the outside and information generated during processing.

The customer display unit 205 is a touch display for customers. The customer display unit 205 displays various information to customers and receives various inputs from customers.
The customer-side scanner unit 206 is a scanner unit for customers, and optically reads various information. For example, the customer-side scanner unit 206 optically reads barcodes (product codes, etc.) attached to products and codes (barcodes, two-dimensional codes, etc.) printed on bills (registered trademarks). In addition to the above, the customer-side scanner unit 206 may read codes (barcodes, two-dimensional codes, etc.) printed on gift certificates (gift certificates, coupons, preferential coupons) and various cards (e.g., membership cards, point cards, etc.). Note that product registration is not limited to registration by reading codes by the customer-side scanner unit 206. For example, a preset key (a button for ordering a product) corresponding to a product may be displayed on the customer-side display unit 205, and the product may be registered by operating (pressing) the preset key by the customer.

The card payment unit 208 is a payment mechanism that uses various cards (credit cards, prepaid cards such as transportation cards, point cards, etc.). The card payment unit 208 is equipped with a card recognition unit (reading unit), a display unit, and an operation unit. The card recognition unit magnetically or electrically reads information from various cards. The read information is used to pay for the purchased items. The card recognition unit can also recognize information to be used in the payment for the current purchased items, for example, when using points held on a point card. The card recognition unit can also recognize information that is not used in the payment for the current purchased items, for example, when points are awarded to a point card.

The card payment unit 208 of this embodiment includes a card recognition unit, a display unit, and an operation unit, but is not limited to these and may include at least a card recognition unit. The card recognition unit of this embodiment is capable of recognizing both contact-type cards (IC cards, magnetic cards) and non-contact-type cards (IC cards), but may only need to be capable of recognizing at least one of them.

The change machine 209 (cash settlement unit) is a mechanism for settlement by cash. The change machine 209 faces the customer side and accepts various operations and cash insertion from the customer. Specifically, as shown in FIG. 2, the change machine 209 has a bill insertion port 209a, a coin insertion port 209b, a change return lever 209c, a bill ejection port 209d, and a coin ejection port 209e. The change machine 209 calculates the total amount of the bills inserted into the bill insertion port 209a and the coins inserted into the coin insertion port 209b, calculates the change amount, which is the difference between the total amount inserted and the purchase amount, and, upon receiving the operation of the change return lever 209c, ejects the change from the bill ejection port 209d or the coin ejection port 209e.

The clerk-side display unit 210 is a touch display for the clerk. The clerk-side display unit 210 displays various information to the clerk and accepts various inputs from the clerk. For example, a preset key (a button for ordering a product) corresponding to a product is displayed on the clerk-side display unit 210, and the product is registered by the clerk operating (pressing) the preset key.

The store clerk scanner unit 212 is a scanner unit for store clerks, and optically reads various types of information. For example, the store clerk scanner unit 212 optically reads barcodes attached to products and store clerk codes attached to store clerk nametags. In addition to the above, the store clerk scanner unit 212 may also read codes printed on bills, gift certificates, and various cards.

Note that product registration is not limited to registration by reading a code using the store clerk's scanner unit 212. For example, the POS terminal device 20 may be equipped with a key operation unit, in which a key corresponding to a product is arranged, and the product may be registered by the store clerk operating (pressing) the key.

The printing unit 213 prints and outputs various documents such as payment slips (receipts, invoices, meal tickets) and instruction slips.

The audio output unit 214 outputs audio. For example, the audio output unit 214 outputs audio guidance, notification sounds, etc. The audio guidance and notification sounds include sounds related to product registration and settlement, as well as sounds related to the issuance of an instruction slip.
The communication unit 215 is an interface for transmitting and receiving information to and from other devices (the order terminal 30 and the kitchen printer 40).

Camera 216 is attached to the upper right of customer display unit 205 when viewed from the customer side. Camera 216 is a camera that continuously captures moving or still images. A CCD (charge coupled device) camera or a CMOS (charge coupled device) camera may be used as camera 216. Camera 216 captures images of the customer's operations during the payment process. Specifically, camera 216 captures images of bills and coins held by the customer, change dispenser 209, hand movements, etc.

(Example of Hardware Configuration of Order Terminal Device 30)
Fig. 4 is an explanatory diagram showing an example of a hardware configuration of the order terminal 30. In Fig. 4, the order terminal 30 includes a CPU 301, a memory 302, a display unit 303, an operation unit 304, a communication unit 305, and an audio output unit 306.

The CPU 301 is a central processing unit that controls the operation of the order terminal 30 by reading and executing programs stored in the memory 302 .

The audio output unit 306 outputs sounds. For example, the audio output unit 306 outputs operation sounds when the display unit 303 or the operation unit 304 receives an operation input, and outputs various notification sounds and warning sounds.

(Example of Hardware Configuration of Kitchen Printer Device 40)
5 is an explanatory diagram showing an example of the hardware configuration of kitchen printer 40. In FIG. 5, kitchen printer 40 includes a CPU 401, a memory 402, a display unit 403, an operation unit 404, a communication unit 405, an audio output unit 406, and a printing unit 407.

The CPU 401 is a central processing unit that controls the operation of the kitchen printer device 40 by reading and executing programs stored in the memory 402 .
The memory 302 includes an auxiliary storage device and a main storage device for the CPU 401, and stores various information used by the CPU 401, including the product sales data processing program according to this embodiment.

The display unit 403 is a touch panel display unit that displays images and accepts various operations from a store clerk.
The operation unit 404 is a set of hard keys that accept various operations from a store clerk.
The communication unit 405 communicates with the POS terminal 20 and the order terminal 30 via the in-store network.
The audio output unit 406 outputs sounds. For example, the audio output unit 406 outputs various notification sounds and warning sounds.
The printing unit 407 prints and outputs the instruction slip.

(When the kitchen printer 40 cannot issue an instruction slip)
Here, the kitchen printer 40 may be unable to output cooking instructions due to a malfunction or communication problem, and may be unable to issue an instruction slip, for example. If the kitchen printer 40 is unable to issue an instruction slip, it is possible to have the POS terminal 20 issue the instruction slip instead of the kitchen printer 40. Specifically, if the kitchen printer 40 is unable to issue an instruction slip, the order terminal 30 sends the accepted order details and an instruction to issue an instruction slip to the POS terminal 20. Upon receiving the order details and the instruction from the order terminal 30, the POS terminal 20 prints out the instruction slip.

However, if the POS terminal 20 were always able to issue instruction slips, depending on the state of the POS terminal 20, it could interfere with the operation of the store clerk using the POS terminal 20, or the store clerk might not be able to understand the issued instruction slips. This would prevent the kitchen staff from starting cooking properly, and it would take time to complete the cooking, making customers wait.

The POS terminal device 20 according to this embodiment is therefore designed to determine the state of its own device when it is not possible for the kitchen printer device 40 to issue an instruction slip, and to issue an instruction slip based on the determined state. The functional configuration of the POS terminal device 20 is described below.

(Functional Configuration of POS Terminal Device 20)
In this embodiment, the POS system 1 includes a POS terminal 20, an order terminal 30, and a kitchen printer 40. The POS terminal 20 is an example of a payment terminal. The order terminal 30 is an example of an ordering terminal. The kitchen printer 40 is an example of a cooking instruction output device.

The POS terminal device 20 of this embodiment includes a settlement unit, a discrimination unit, an output control unit, a reception unit, and a notification unit. Each of these units is realized by the CPU 201 of the POS terminal device 20. That is, the CPU 201 of the POS terminal device 20 executes a predetermined program (a product sales data processing program) to realize the functions of each unit.

The settlement unit executes a settlement process to settle the purchased items (accounting items). The settlement process includes multiple processes. Specifically, the settlement process includes an item input process that accepts the input of accounting items from the store clerk, a payment process that accepts the selection of the payment type and the insertion of cash from the customer and gives out change, and a settlement slip issuance process that outputs a settlement slip such as a receipt.

For example, the transaction item input process is a process of inputting information about transaction items used in settlement. Specifically, the transaction item input process may be a process in which a store clerk checks each transaction item listed on the order slip and inputs it manually. In addition, if the POS terminal device 20 is configured to store transaction identification information in association with transaction items, the transaction item input process may be a process in which a store clerk inputs the transaction identification information listed on the order slip to obtain the transaction item associated with the transaction identification information. In addition, if the transaction item is represented by a two-dimensional code or the like, the transaction item may be input by having the store clerk's scanner unit 212 read the two-dimensional code.

The payment process is a process in which the payment procedure is carried out according to the payment type. The payment process may be carried out in parallel with the accounting item input process, or may be carried out after the accounting item input process. The settlement slip issuance process is carried out using the printing unit 213 after the payment process is completed.

The discrimination unit discriminates the state of the POS terminal device 20 when the kitchen printer device 40 is unable to issue an instruction slip. Circumstances when the kitchen printer device 40 is unable to issue an instruction slip include, for example, when the kitchen printer device 40 has broken down or is unable to receive the order contents due to a communication failure, etc.

The state of the POS terminal 20 determined by the determination unit includes, for example, a store clerk-present state in which a store clerk is present near the POS terminal 20, and a store clerk-absent state in which a store clerk is not present near the POS terminal 20. The store clerk-present state is, for example, a state in which a store clerk can operate the POS terminal 20, and more specifically, a state in which a store clerk is logged in to the POS terminal 20. On the other hand, the store clerk-absent state is a state in which a store clerk is not present around the POS terminal 20, and for example, a state in which a store clerk is not logged in to the POS terminal 20.

If the POS terminal device 20 is equipped with a camera that captures images of the surroundings of the device, it is possible to detect store clerks around the POS terminal device 20 using the captured images from the camera. In this case, the discrimination unit may determine a state in which a store clerk is detected as a store clerk present state, and a state in which a store clerk is not detected as a store clerk absent state.

The output control unit outputs cooking instructions based on the determination result of the state of the POS terminal device 20 by the determination unit. The output of the cooking instructions is, for example, the issuance of an instruction slip indicating the cooking instructions. However, the output of the cooking instructions is not limited to this, and may be, for example, a display output from a display unit such as the store clerk display unit 210, or an audio output from the audio output unit 214. Note that, below, the output of the cooking instructions is described as the issuance of a cooking slip.

The output control unit may or may not issue an instruction slip depending on the state of the POS terminal device 20 determined by the determination unit. When issuing an instruction slip, the output control unit may issue the instruction slip automatically or in response to an operation by a store clerk.

The output control unit issues an instruction slip based on the result of the discrimination unit's discrimination of whether a store clerk is present. Specifically, the output control unit enables the issuance of an instruction slip when the discrimination unit discriminates that a store clerk is present. On the other hand, the output control unit restricts the issuance of an instruction slip when the discrimination unit discriminates that a store clerk is absent. Restricting the issuance of an instruction slip means to uniformly prevent the issuance of an instruction slip or to prevent the issuance of an instruction slip depending on certain conditions.

When the discrimination unit determines that the state is a store clerk presence state, it further discriminates whether or not the state is a customer service operation state, which indicates that a store clerk is performing operations to serve the customer. The customer service operation state includes, for example, a state in which a settlement process (including a transaction product input process, a payment process, and a settlement slip issuance process) is being performed.

The output control unit issues an instruction slip based on the determination result of the clerk presence state and the customer service operation state by the determination unit. For example, from the viewpoint of preventing the issuance of an instruction slip from interfering with customer service operations, the output control unit restricts the issuance of an instruction slip when the determination unit determines that a customer service operation state is in place, even when a clerk presence state is determined by the determination unit. In particular, from the viewpoint of preventing the mixing of settlement slips such as receipts and instruction slips, the output control unit does not issue an instruction slip if the settlement slip issuance process is being performed even in the customer service operation state. However, the output control unit does not issue an instruction slip if the timing is before the settlement slip issuance process is performed even in the customer service operation state. The output control unit may automatically issue an instruction slip after issuing a settlement slip.

It may be difficult to determine whether the kitchen printer 40 can print an instruction slip. For example, a malfunction may be temporarily fixed, making it possible to print an instruction slip. In view of this, the POS terminal 20 may be able to switch to a setting that prints a cooking slip. This switching may be automatic or manual.

The order terminal 30 is a terminal that accepts orders. The order terminal 30 is carried by a store clerk and accepts orders in response to the operation of the store clerk. However, the order terminal 30 is not limited to being carried by a store clerk, and may be placed at each table, for example. In this case, the order terminal 30 may accept orders in response to the operation of a customer. The order terminal 30 may be capable of switching between a store clerk specification mode carried by a store clerk (a mode in which orders are accepted in response to the operation of a store clerk) and a customer use mode placed on a table (a mode in which orders are accepted in response to the operation of a customer). Furthermore, the POS terminal 20 may accept orders instead of or in addition to the order terminal 30. The output control unit causes the order terminal 30 to issue an instruction slip for the product accepted.

The notification unit issues notifications regarding the issuance of an instruction slip by the output control unit. Notifications regarding issuance include, for example, an issued notification indicating that an instruction slip has been issued, and an issuance waiting notification indicating that an instruction slip is waiting to be issued. An issuance waiting notification includes, for example, a prompt to encourage the store clerk to issue an instruction slip while waiting. The notification unit issues the notification using the order terminal device 30, the store clerk side display unit 210, or the audio output unit 214. In addition, if the POS terminal device 20 is equipped with a sign pole such as an issuance lamp, the notification unit may light up the sign pole in a lighting mode corresponding to the content of the notification.

The reception unit receives an instruction to start issuing an instruction slip if the output control unit has not issued an instruction slip. The reception unit, for example, displays a button (instruction slip issue button) that accepts the issuance of an instruction slip on the store clerk display unit 210, and accepts pressing of the button from the store clerk. The reception unit displays the instruction slip issue button, for example, when the notification unit issues an issuance standby notification.

The output control unit causes the issuance of the instruction slip to wait until the reception unit receives an instruction to start issuance. When the reception unit receives an instruction to start issuance, the output control unit causes the issuance of the instruction slip.

The reception unit may also be configured to accept login input on the login input screen as an instruction to start issuing an instruction slip. In this case, when the reception unit accepts the login input and the login is successful, the output control unit may be configured to issue an instruction slip. The reception unit may also accept input of a clerk code as an instruction to start issuing an instruction slip. The clerk code may be input by operation, or may be input by reading with the clerk-side scanner unit 212. In this case, when the reception unit accepts input of a registered clerk code, the output control unit may be configured to issue an instruction slip.

(Processing performed by each device)
Next, a description will be given of the processes performed by the POS terminal 20, the order terminal 30, and the kitchen printer 40. First, a description will be given of the processes performed by the kitchen printer 40.

(Processing performed by kitchen printer device 40)
Fig. 6 is an explanatory diagram showing an example of the process performed by kitchen printer 40. As shown in Fig. 6, kitchen printer 40 judges whether or not it has received the order details from order terminal 30 (step S601). Kitchen printer 40 waits until it receives the order details (step S601: NO), and when it receives the order details (step S601: YES), it judges whether or not there is an error related to the production of the instruction slip (step S602).

If there is no abnormality related to the issuance of the instruction slip (step S602: YES), i.e., if everything is normal, the kitchen printer 40 issues an instruction slip (step S603). The kitchen printer 40 then sends an issuance completion notification to the order terminal 30 indicating that the instruction slip has been issued (step S604), and ends the series of processes. On the other hand, if there is an abnormality related to the issuance of the instruction slip (step S602: NO), the kitchen printer 40 sends an issuance failure notification to the order terminal 30 indicating that the instruction slip cannot be issued (step S605), and ends the series of processes.

(Processing performed by the order terminal 30)
Fig. 7 is an explanatory diagram showing an example of the process performed by the order terminal 30. As shown in Fig. 7, the order terminal 30 judges whether or not an order has been received from a waiter or a customer (step S701). The order terminal 30 waits until an order is received (step S701: NO), and when an order is received (step S701: YES), it transmits the received order details to the kitchen printer 40 (step S702).

Then, the order terminal 30 judges whether or not an issuance completion notice indicating that the instruction slip has been issued has been received from the kitchen printer 40 (step S703). If the order terminal 30 receives an issuance completion notice (step S703: YES), it displays an order acceptance completion screen (see FIG. 9B) (step S704) and ends the series of processes.

On the other hand, if the issuance completion notification is not received (step S703: NO), the order terminal 30 judges whether or not an issuance impossible notification indicating that the instruction slip cannot be printed has been received from the kitchen printer 40 (step S705). If an issuance impossible notification has been received (step S705: YES), the order terminal 30 proceeds to step S707. If an issuance impossible notification has not been received (step S705: NO), the order terminal 30 judges whether or not a predetermined response time has elapsed (step S706).

If the predetermined response time has not elapsed (step S706: NO), the order terminal 30 returns to step S703. If the predetermined response time has elapsed (step S706: YES), i.e., if there is no response (notification of issuance completion or notification of issuance not possible) from the kitchen printer 40 despite the order details being sent to the kitchen printer 40 due to radio interference with the kitchen printer 40 or the like, the order terminal 30 sends the order details to the POS terminal 20 together with an issuance instruction to have the POS terminal 20 issue an instruction slip (step S707).

The order terminal 30 then determines whether it has received issuance-related information regarding the issuance of an instruction slip at the POS terminal 20 from the POS terminal 20 (step S708). The issuance-related information is information indicating that an instruction slip has been issued at the POS terminal 20, or information indicating that the POS terminal 20 is waiting to issue an instruction slip. The order terminal 30 waits until it receives the issuance-related information (step S708: NO), and upon receiving the issuance-related information (step S708: YES), it determines whether it is in a clerk-used state (step S709). If the order terminal 30 is not in a clerk-used state, i.e., in a customer-used state (used by a customer), the order terminal 30 ends the series of processes. On the other hand, if the order terminal 30 is in the store clerk use mode, the order terminal 30 displays a notification screen according to the issuance-related information (the issued notification screen in FIG. 9(C) or the issuance waiting notification screen in FIG. 9(D)) (step S710), and ends the series of processes.

(Processing performed by POS terminal device 20)
Fig. 8 is an explanatory diagram showing an example of processing performed by the POS terminal 20. As shown in Fig. 8, the POS terminal 20 judges whether or not it has received an order from the order terminal 30 together with an issuance instruction for the POS terminal 20 to issue an instruction slip due to the inability of the kitchen printer 40 to issue an instruction slip (step S801). The POS terminal 20 waits until it receives the order (step S801: NO). When it receives the order (step S801: YES), the POS terminal 20 judges whether or not a store clerk is present (for example, a store clerk is logged in to the POS terminal 20) (step S802).

If no staff member is present (step S802: NO), i.e., if the staff member is absent, such as in a standby state, the POS terminal device 20 issues a staff member absence issuance standby notification (see FIG. 11(B)) to prompt the staff member to issue an instruction slip (step S803), and proceeds to step S806. In this notification, a notification image is displayed on the staff display unit 210, and a notification sound is output, prompting the hall staff member or kitchen staff member to issue an instruction slip.

On the other hand, if a store clerk is present in step S802 (step S802: YES), the POS terminal 20 judges whether or not the store clerk is in a customer service operation state (payment processing in progress) (step S804). If the store clerk is not in a customer service operation state (step S804: NO), that is, for example, if the store clerk is logged in to the POS terminal 20 but is performing an operation other than a payment processing operation (for example, performing maintenance or tallying), the POS terminal 20 proceeds to step S809.

On the other hand, if the POS terminal 20 is in a customer service operation state (step S804: YES), the POS terminal 20 issues a wait-for-issuance notification (see FIG. 11A) in the customer service operation state to prompt the clerk to issue an instruction slip after the customer service operation (step S805). In this notification, a notification image is displayed on the clerk-side display unit 210 to prompt the clerk who is currently operating the customer service operation to issue an instruction slip.

The POS terminal 20 then displays an instruction slip issue button (see FIG. 11) on the store clerk display unit 210 to accept the issuance of an instruction slip (step S806). Next, the POS terminal 20 transmits issuance-related information indicating that the issuance of an instruction slip is pending to the order terminal 30 (step S807).

The POS terminal 20 then determines whether the instruction slip issue button has been pressed (step S808). The POS terminal 20 waits until the instruction slip issue button is pressed (step S808: NO), and when the instruction slip issue button is pressed (step S808: YES), it issues an instruction slip (step S809). Note that if the POS terminal 20 is not in a customer service operation state (step S804: NO), that is, if a store clerk is logged into the POS terminal 20 but is not processing a payment, the POS terminal 20 issues an instruction slip without the need to press the instruction slip issue button or to be notified that an instruction slip is waiting to be issued (step S809). Note that when issuing the instruction slip in step S809, the POS terminal 20 may issue a notification that an instruction slip will be issued or that an instruction slip has been issued.

Then, the POS terminal 20 transmits issuance-related information indicating that the instruction slip has been issued to the order terminal 30 (step S810). Next, the POS terminal 20 issues an issued notification indicating that the instruction slip has been issued using the store clerk display unit 210 or the like (step S811), and ends the series of processes. The issued notification is issued, for example, by voice or display.

(Example of a screen displayed on the display unit 303 of the order terminal device 30)
Next, an example of a screen displayed on the display unit 303 of the order terminal 30 will be described with reference to Fig. 9. Fig. 9 is an explanatory diagram showing an example of a screen displayed on the display unit 303 of the order terminal 30.

Figure 9 (A) shows a reception screen 900 when receiving an order. The reception screen 900 includes multiple selection buttons 901 corresponding to each menu (dish) and an order confirmation button 902. For example, when "Pasta Lunch" is pressed among the selection buttons 901, a quantity specification display 903 is displayed. When the waiter specifies the quantity on the quantity specification display 903 and presses the order confirmation button 902, the screen transitions to one of the screens shown in Figures 9 (B) to (D).

Figure 9 (B) shows an order acceptance completion screen 910 that is displayed when the kitchen printer device 40 is normal (when there are no abnormalities related to the issuance of the instruction slip). The order acceptance completion screen 910 includes an order acceptance completion notice 911. The order acceptance completion notice 911 indicates that an instruction slip for "pasta lunch" has been issued by the kitchen printer device 40 and that the order has been accepted normally. When the OK button 912 on the order acceptance completion notice 911 is pressed, the screen returns to one that can accept orders again.

Figure 9 (C) shows an issued notification screen 920 that is displayed when there is an abnormality in the kitchen printer device 40 (when there is an abnormality related to the issuance of the instruction slip). The issued notification screen 920 includes an issued notification 921. The issued notification 921 indicates that the kitchen printer device 40 cannot issue an instruction slip and that the instruction slip has been issued by the POS terminal device 20. Note that the instruction slip is issued when a store clerk is present near the POS terminal device 20. When the OK button 922 on the issued notification screen 920 is pressed, the screen returns to one that can accept orders again.

Figure 9 (D) shows a standby notification screen 930 that is displayed when there is an abnormality in the kitchen printer 40 (when there is an abnormality related to issuing an instruction slip). The standby notification screen 930 includes a standby notification 931. The standby notification 931 indicates that the kitchen printer 40 cannot issue a slip, that the POS terminal 20 will issue an instruction slip, and that the screen is waiting for the instruction slip to be issued. When the OK button 932 on the standby notification screen 930 is pressed, the screen returns to the screen where the order can be accepted again. Note that after the OK button 932 is pressed, a mark indicating the standby state may be displayed until the POS terminal 20 issues an instruction slip.

(Example of an instruction slip)
Next, an example of an instruction slip issued by kitchen printer 40 or POS terminal 20 will be described with reference to FIG. 10. FIG. 10 is an explanatory diagram showing an example of an instruction slip. As shown in FIG. 10, an instruction slip 1000 (1000a to 1000e) is issued each time kitchen printer 40 accepts an order. Instruction slip 1000 includes a slip number, date and time, product name, person in charge, and seat number. The slip number is identification information that identifies instruction slip 1000. The date and time indicates the time when the order was accepted. The product name indicates the accepted menu item (order). The person in charge indicates information that identifies the waiter who accepted the order. The seat number indicates the seat number (table number) of the seat where the customer who placed the order is sitting.

The order slips 1000a-1000e have cuts so that they can be separated. The kitchen staff checks the order slips 1000a-1000e and starts cooking. For example, when cooking of the "strawberry roll cake" corresponding to the order slip 1000a is completed, the order slip 1000a is attached to the "strawberry roll cake" and handed over to the hall staff. The hall staff checks the contents of the order slip 1000a and serves the "strawberry roll cake" to the seat indicated by the seat number on the order slip 1000a.

(Example of a screen displayed on the store clerk display unit 210 of the POS terminal device 20)
Next, an example of a screen displayed on the clerk display unit 210 of the POS terminal 20 will be described with reference to Fig. 11. Fig. 11 is an explanatory diagram showing an example of an issuance standby notification screen displayed on the clerk display unit 210 of the POS terminal 20.

Figure 11 (A) shows a waiting notification screen 1100 during customer service operation (payment processing). The waiting notification screen 1100 includes a product registration button 1101, a transaction product display area 1102, a reminder notification 1103, and an instruction ticket issue button 1104.

The product registration button 1101 is a button that accepts the input of the products (items) consumed by the customer. For example, a store clerk checks the order slip and operates the product registration button 1101 to input the items. When the product registration button 1101 is pressed, the items corresponding to the pressed button are displayed in the item display area 1102. The item display area 1102 also includes the items, the price, the subtotal, the deposit, and the change.

The issuance urging notice 1103 indicates that the kitchen printer device 40 cannot issue an instruction slip (for example, that it is broken) and prompts the user to issue an instruction slip after the settlement process is completed. The instruction slip issue button 1104 accepts the issuance of an instruction slip. For example, even if the settlement process is not completed, an instruction slip is issued when the instruction slip issue button 1104 is pressed. In other words, it is possible to issue an instruction slip even when the user is in a customer service operation state.

Figure 11 (B) shows an issuance waiting notification screen 1110 when a store clerk is absent. The issuance waiting notification screen 1110 shows, for example, a waiting screen. The issuance waiting notification screen 1110 includes an issuance urging notification 1111. The issuance urging notification 1111 shows that the kitchen printer device 40 cannot issue an instruction slip (for example, that it is broken) and urges the user to log in and issue an instruction slip. In addition, when the issuance waiting notification screen 1110 is displayed, an alarm sound 1112 is also output. When a store clerk logs in and presses the instruction slip issue button 1104, an instruction slip is issued.

As described above, in the POS system 1 of the first embodiment, when the kitchen printer 40 is unable to issue an instruction slip, the POS terminal 20 issues an instruction slip based on the result of determining the state of the POS terminal 20. This allows the POS terminal 20 to issue an instruction slip at an appropriate time according to the state of the POS terminal 20. For this reason, for example, if the kitchen printer 40 is unable to issue an instruction slip due to a malfunction or the like, even if the POS terminal 20 issues an instruction slip, it is possible to prevent the clerk operating the POS terminal 20 from being hindered, and the clerk from being unable to understand the issued instruction slip. Therefore, the kitchen clerk can start cooking appropriately, which prevents the time required to complete cooking from being taken, and therefore prevents customers from having to wait. As a result, the POS system 1 of the first embodiment allows instruction slips to be issued appropriately.

The POS terminal device 20 also issues an instruction slip based on the result of determining whether or not a store clerk is present. This makes it possible to prevent an instruction slip from being issued when a store clerk is not present, thereby preventing the store clerk from forgetting to pick up the instruction slip. In addition, since an instruction slip can be issued when a store clerk is present, an instruction slip can be issued quickly and the store clerk can properly understand that it has been issued.

In addition, when a store clerk is present, the POS terminal device 20 issues an instruction slip based on the result of determining whether or not the store is in a customer service operation state. This makes it possible to prevent an instruction slip from being issued when a store clerk is present and in a customer service operation state (during settlement processing). This prevents a mix-up of settlement slips such as receipts and instruction slips, and allows for the optimal issuance of instruction slips.

In addition, in the first embodiment, the POS terminal device 20 is configured to cause the order terminal device 30 to issue an instruction slip for the product that has been accepted. This allows the order terminal device 30 to cause the POS terminal device 20 to issue an instruction slip for the product that has been ordered at the appropriate time.

In addition, in the first embodiment, if the POS terminal device 20 does not issue an instruction slip, it displays an instruction slip issue button 1104 that accepts an instruction to start issuing an instruction slip. This allows the instruction slip to be issued at the desired timing.

In addition, in the first embodiment, the POS terminal device 20 uses the order terminal device 30, the store clerk display unit 210, etc. to notify the store clerk when an instruction slip has been issued or is waiting to be issued, so the store clerk can easily know when an instruction slip has been issued or when an instruction slip has not been issued.

Other embodiments and modifications
Other embodiments and modifications will be described below. In addition, in the other embodiments and each modification, the contents described in the above-mentioned embodiment 1 will be omitted as appropriate. In addition, it is also possible to combine the configurations shown in each embodiment and each modification. Specifically, for example, it is possible to have a configuration that includes all of the embodiments and each modification, or a configuration that combines two or more of the embodiments and each modification.

(First Modification of First Embodiment)
First, a first variation of the first embodiment will be described. In the first embodiment described above, the contents notified by the order terminal 30 are an issued notification and an issuance waiting notification. In addition to or instead of this configuration, in the first variation of the first embodiment, the contents notified by the order terminal 30 may also include the status of the POS terminal 20.

In the first variation of the first embodiment, the order terminal 30 notifies the POS terminal 20 that an instruction slip can be issued when it is possible. For example, when the POS terminal 20 issues a standby notification that a store clerk is not present, the POS terminal 20 is not processing the settlement, and therefore is able to issue an instruction slip. For this reason, when the POS terminal 20 issues a standby notification that a store clerk is not present, it may notify the order terminal 30 that an instruction slip can be issued. At this time, the order terminal 30 may display an instruction slip issue button to accept the issuance of an instruction slip. When the hall clerk presses the instruction slip issue button displayed on the order terminal 30, the hall clerk may go to the POS terminal 20, receive the instruction slip, and hand it over to the kitchen clerk.

According to the first variation of the first embodiment, when the POS terminal device 20 is able to issue an instruction slip, it notifies the order terminal device 30 of that fact, so that the store clerk can be prompted to issue the instruction slip, and the instruction slip can be issued quickly.

(Modification 2 of the First Embodiment)
Next, a second modification of the first embodiment will be described. In the first embodiment described above, the direction of the medium issuing port of the printing unit 213 is fixed. In addition to or instead of this configuration, in the second modification of the first embodiment, the direction of the medium issuing port of the printing unit 213 may be changeable.

In the second variation of the first embodiment, the printing unit 213 has, for example, a mechanism that can rotate or pivot freely, and is configured so that the media issuing port faces from the clerk side to the customer side, and vice versa. The orientation of the media issuing port may be manually changeable, or may be automatically changeable depending on the type of document to be printed. For example, when issuing an instruction slip, the media issuing port may be facing the clerk side, and when issuing a payment slip, the media issuing port may be facing the customer side.

According to the second variant of the first embodiment, the orientation of the medium issuing port can be changed depending on the type of document to be printed, which prevents the mixing of settlement slips and instruction slips and allows instruction slips to be issued optimally.

(Variation 3 of the First Embodiment)
Next, a third variation of the first embodiment will be described. In the first embodiment described above, an example of the cooking instruction output device is a kitchen printer device 40. In a third variation of the first embodiment, in addition to or instead of the above configuration, a kitchen monitor 50 is used as an example of the cooking instruction output device.

In variant 3, the kitchen monitor 50 may be unable to display cooking instruction information due to a malfunction, communication failure, or the like. If the kitchen monitor 50 is unable to display cooking instruction information, it is possible to have the POS terminal device 20 display the cooking instruction information instead of the kitchen monitor 50. Specifically, if the kitchen monitor 50 is unable to display cooking instruction information, the order terminal device 30 transmits the received order details and an instruction to display the cooking instruction information to the POS terminal device 20. When the POS terminal device 20 receives the order details and the instruction to display from the order terminal device 30, it displays the cooking instruction information.

The following provides additional information about the functional configuration of the POS terminal device 20 according to the third variation of the first embodiment. The discrimination unit of the POS terminal device 20 discriminates the state of the POS terminal device 20 (e.g., whether a store clerk is present or not) when the kitchen monitor 50 is unable to display cooking instruction information. Examples of cases in which the kitchen monitor 50 is unable to display cooking instruction information include when the kitchen monitor 50 has broken down or is unable to receive the order details due to a communication failure or the like.

The output control unit of the POS terminal device 20 according to the third modification of the first embodiment causes the store clerk display unit 210 to display cooking instruction information based on the determination result of the state of the POS terminal device 20 by the determination unit. The POS terminal device 20 may output the cooking instruction information by voice from the voice output unit 214.

According to the third modification of the first embodiment, when the kitchen monitor 50 cannot display cooking instruction information, the POS terminal 20 displays cooking instruction information based on the result of determining the state of the POS terminal 20. This allows the POS terminal 20 to display cooking instruction information at an appropriate timing according to the state of the POS terminal 20. For this reason, for example, when the kitchen monitor 50 cannot display cooking instruction information due to a malfunction or the like, even if the POS terminal 20 displays cooking instruction information, it is possible to prevent the POS terminal 20 from interfering with the operation of the store clerk, or the store clerk from being unable to understand the displayed cooking instruction information. Therefore, the kitchen staff can start cooking appropriately, so that it is possible to prevent the time required to complete cooking, and therefore to prevent customers from having to wait. As a result, the POS system 1 according to the third modification of the first embodiment can issue instruction slips appropriately.

(Embodiment 2)
Next, a second embodiment will be described. In the first embodiment described above, a configuration in which a store clerk is involved in the settlement is described. In the second embodiment, a configuration in which a store clerk is not involved in the settlement is described. For example, in the second embodiment, the POS terminal 20 is controlled to a self-checkout mode in which the settlement process is performed without the intervention of a store clerk. The POS terminal 20 may be a dedicated device (self-checkout device) for customers to settle the bill. Below, the POS terminal 20 according to the second embodiment may be referred to as a "POS terminal 20 for self-checkout".

(Processing performed by the POS terminal device 20 in the second embodiment)
Fig. 12 is an explanatory diagram showing an example of the process performed by the POS terminal 20 of the second embodiment. As shown in Fig. 12, the POS terminal 20 judges whether or not it has received an issuance instruction for the POS terminal 20 to issue an instruction slip from the order terminal 30 due to the inability of the kitchen printer 40 to issue an instruction slip together with the order details (step S1201). The POS terminal 20 waits until it receives the order details (step S1201: NO). When it receives the order details (step S1201: YES), the POS terminal 20 judges whether or not a store clerk is present (for example, a store clerk is logged in to the POS terminal 20) (step S1202).

If no staff member is present (step S1202: NO), i.e., if no staff member is present, the POS terminal 20 issues a notification of waiting for issuance when staff member is absent (see FIG. 11(B)) to prompt the staff member to issue an instruction slip (step S1203), and proceeds to step S1206. In this notification, a notification image is displayed on the staff display unit 210, and/or a notification sound is output, thereby prompting the hall staff member or kitchen staff member to issue an instruction slip.

On the other hand, if a store clerk is present in step S1202 (step S1202: YES), the POS terminal 20 judges whether or not the customer is currently processing a payment (step S1204). If a payment is not currently being processed (step S1204: NO), that is, for example, if the customer is not present at the POS terminal 20 and a store clerk has logged in to perform maintenance or tallying, the POS terminal 20 proceeds to step S1209.

On the other hand, if the payment is being processed (step S1204: YES), the POS terminal 20, for example, displays on the clerk display unit 210 a screen similar to that displayed on the customer display unit 205, but issues a notification of waiting for issuance during payment (see FIG. 13) on that screen to prompt the clerk to issue an instruction slip after the payment is processed (step S1205). In this notification, a notification image is displayed on the clerk display unit 210 to prompt the logged-in clerk to issue an instruction slip.

The POS terminal 20 then displays an instruction slip issue button (see FIG. 13) on the store clerk display unit 210 to accept the issuance of an instruction slip (step S1206). Next, the POS terminal 20 transmits issuance-related information indicating that the issuance of an instruction slip is pending to the order terminal 30 (step S1207).

The POS terminal 20 then determines whether the instruction slip issue button has been pressed (step S1208). The POS terminal 20 waits until the instruction slip issue button is pressed (step S1208: NO), and when the instruction slip issue button is pressed (step S1208: YES), issues an instruction slip (step S1209). Note that if the payment process is not in progress (step S1204: NO), i.e., if a store clerk is logged into the POS terminal 20 but the customer is not processing the payment, the POS terminal 20 issues an instruction slip without the need to press the instruction slip issue button or receive a notification that the slip is waiting to be issued (step S1209).

Then, the POS terminal 20 transmits issuance-related information indicating that the instruction slip has been issued to the order terminal 30 (step S1210). Next, the POS terminal 20 uses the store clerk display unit 210 or the like to notify the customer that the instruction slip has been issued (step S1211), and ends the series of processes.

(Example of a screen displayed on the store clerk display unit 210 of the POS terminal device 20 according to the second embodiment)
Next, an example of a screen displayed on the store clerk display unit 210 of the POS terminal 20 according to embodiment 2 will be described with reference to Fig. 13. Fig. 13 is an explanatory diagram showing an example of an issuance waiting notification screen 1300 displayed on the store clerk display unit 210 of the POS terminal 20 according to embodiment 2.

The issuance waiting notification screen 1300 shows the screen displayed on the clerk display unit 210 during the settlement process of the self-checkout POS terminal device 20. The issuance waiting notification screen 1300 includes a checkout product display 1301, an issuance reminder notice 1302, and an instruction slip issue button 1303. Note that although the same screen is displayed on the customer display unit 205 and the clerk display unit 210 in the self-checkout POS terminal device 20, in the issuance waiting notification, the issuance reminder notice 1302 and the instruction slip issue button 1303 do not have to be displayed on the customer display unit 205.

The transaction item display 1301 shows a mirrored display that is displayed on the customer display unit 205 during payment in the self-payment mode. The transaction item is displayed on the transaction item display 1301. For example, when a customer has the customer scanner unit 206 read a two-dimensional code indicating the transaction identification information written on a receipt, the transaction item is displayed on the transaction item display 1301. The transaction item display 1301 also includes the transaction item, price, subtotal amount, deposit, and change.

The issuance urging notice 1302 indicates that the kitchen printer device 40 cannot issue an instruction slip (for example, that it is broken) and prompts the user to issue an instruction slip after self-payment. The instruction slip issue button 1303 accepts the issuance of an instruction slip. For example, even if self-payment has not been completed, an instruction slip is issued when the instruction slip issue button 1303 is pressed. In other words, even during payment processing, it is possible to issue an instruction slip in response to an operation by a store clerk. However, if it were possible to issue an instruction slip at the timing when a payment slip (receipt) is issued during payment processing (timing of payment slip issuance processing), there is a risk that payment slips and instruction slips will be mixed up. For this reason, it may be possible to prevent the issuance of an instruction slip during payment slip issuance processing.

Although not shown in the figure, the issuance waiting notification screen when a store clerk is not present on the self-payment POS terminal device 20 can be a screen similar to the issuance waiting notification screen 1110 shown in FIG. 11 (B).

As described above, in the POS system 1 of the second embodiment, the self-checkout POS terminal 20 issues an instruction slip based on the determination of its own status when the kitchen printer 40 is unable to issue an instruction slip. This allows the self-checkout POS terminal 20 to issue an instruction slip at an appropriate time according to its own status. Therefore, for example, if the kitchen printer 40 is unable to issue an instruction slip due to a malfunction or the like, even if the self-checkout POS terminal 20 is caused to issue an instruction slip, it is possible to prevent interference with the operation of the customer using the POS terminal 20 and the store clerk being unable to understand the issued instruction slip.

(Embodiment 3)
A third embodiment will be described below. In the first embodiment described above, the POS system 1 equipped with the order terminal 30 is described. In the third embodiment, a POS system 1400 not equipped with the order terminal 30 is described. Specifically, in the third embodiment, a case where the POS terminal 20 accepts an order is described.

Figure 14 is an explanatory diagram showing an example of the network configuration of a POS system 1400 according to embodiment 3. As shown in Figure 14, the POS system 1400 according to embodiment 3 includes a management device 10, a POS terminal device 20, a kitchen printer device 40, and a kitchen monitor 50. In the figure, two POS terminal devices 20 are shown, but there may be one, or three or more.

(Functional configuration of the POS terminal device 20 according to the third embodiment)
The following describes the functional configuration of the POS terminal 20 used in the POS system 1 according to the third embodiment. The POS terminal 20 according to the third embodiment includes a mode control unit. The mode control unit is realized by the CPU 201 of the POS terminal 20. That is, the CPU 201 of the POS terminal 20 executes a predetermined program (a product sales data processing program) to realize the functions of the mode control unit.

The mode control unit controls one of a plurality of operation modes. The plurality of operation modes include a clerk-assisted mode and a self-operation mode. The clerk-assisted mode is an operation mode in which a clerk is involved in the product purchase procedure. In the third embodiment, the clerk-assisted mode is an operation mode in which a clerk performs product registration operations in response to a customer's request, and the customer meets the clerk to pay for the registered product (hereinafter referred to as the "clerk registration mode").

Self-service mode is a mode in which the customer registers the products and completes the purchase procedure themselves, without the intervention of a store clerk. In the third embodiment, the self-service mode is described as an operation mode in which the customer selects (registers) the products to be purchased, settles the bill, and issues a meal ticket (hereinafter referred to as "ticket vending machine mode"). The POS system 1400 is installed in a store that operates in different operation modes depending on the time of day. For example, the POS system 1400 is installed in a store that operates in clerk-assisted mode during times when there are many customers (e.g., daytime) and in ticket vending machine mode during times when there are few customers (e.g., at night).

The discrimination unit discriminates whether the state of the POS terminal device 20 is in one of a number of operating modes, including a store clerk intervention mode and a ticket vending machine mode. The output control unit issues an instruction slip based on the result of the discrimination unit's discrimination of the operating mode. Specifically, when the discrimination unit determines that the store clerk intervention mode is in effect, the output control unit enables the issuance of an instruction slip. On the other hand, when the discrimination unit determines that the ticket vending machine mode is in effect, the output control unit restricts the issuance of an instruction slip.

When the discrimination unit determines that the mode is the ticket vending machine mode, it further discriminates whether or not a store clerk is present near the POS terminal device 20. The output control unit issues an instruction slip based on the discrimination result of the operation mode and the discrimination result of the store clerk presence state by the discrimination unit. Specifically, the output control unit enables the issuance of an instruction slip if it is determined that a store clerk is present even when the discrimination unit determines that the mode is the ticket vending machine mode.

Furthermore, when the discrimination unit determines that a store clerk is present in the ticket vending machine mode, it further discriminates whether or not a settlement process is in progress. The settlement process is, for example, a meal ticket purchasing process. The meal ticket purchasing process includes a process for accepting a meal ticket selection, a payment process, and a settlement slip issuing process for issuing a meal ticket and a receipt. The output control unit issues an instruction slip based on the discrimination unit's determination of whether a store clerk is present and the determination that a settlement process is in progress (meal ticket purchasing process in progress). Specifically, the output control unit restricts the issuance of an instruction slip if it determines that a store clerk is present by the discrimination means but that a settlement process is in progress.

The output control unit may not restrict the issuance of an instruction slip when the discrimination unit determines that the mode is the ticket vending machine mode. For example, in the ticket vending machine mode, the output control unit may issue an instruction slip at the same time as the meal ticket is issued. The POS terminal device 20 may also notify the customer to hand the issued instruction slip to a store clerk. The notification may be given by writing it on the meal ticket, or by displaying it on the customer side display unit 205.

(Processing performed by the POS terminal device 20 according to the third embodiment)
Fig. 15 is an explanatory diagram showing an example of processing performed by the POS terminal 20 according to the third embodiment. As shown in Fig. 15, the POS terminal 20 judges whether an order has been received from a store clerk or a customer (step S1501). The POS terminal 20 receives orders from store clerks when controlled in the store clerk registration mode, and receives orders from customers when controlled in the ticket vending machine mode. The POS terminal 20 waits until it receives an order (step S1501: NO), and when it receives an order (step S1501: YES), it transmits the received order details to the kitchen printer 40 (step S1502).

The POS terminal 20 then determines whether or not an issuance completion notification has been received from the kitchen printer 40, indicating that the instruction slip has been issued (step S1503). If an issuance completion notification has been received (step S1503: YES), the POS terminal 20 ends the series of processes. Note that if an issuance completion notification has been received, the POS terminal 20 may display a screen indicating that the order has been accepted.

On the other hand, if the issuance completion notification is not received (step S1503: NO), the POS terminal 20 determines whether an issuance impossible notification has been received from the kitchen printer 40 indicating that the instruction slip cannot be printed (step S1504). If an issuance impossible notification has been received (step S1504: YES), the POS terminal 20 proceeds to step S1506. If an issuance impossible notification has not been received (step S1504: NO), the POS terminal 20 determines whether a predetermined response time has elapsed (step S1505).

If the predetermined response time has not elapsed (step S1505: NO), the POS terminal 20 returns to step S1503. If the predetermined response time has elapsed (step S1505: YES), that is, if there is no response (notification of issuance completion or issuance failure) from the kitchen printer 40 despite the order details being sent to the kitchen printer 40 due to radio interference with the kitchen printer 40, the POS terminal 20 determines whether the current operating mode is the ticket vending machine mode (step S1506).

If the current operating mode is not the ticket machine mode (step S1506: NO), i.e., if the current operating mode is the store clerk registration mode, the POS terminal 20 proceeds to step S1513. If the current operating mode is the ticket machine mode (step S1506: YES), the POS terminal 20 determines whether a store clerk is present (e.g., a store clerk is logged in to the POS terminal 20) (step S1507).

If no staff member is present (step S1507: NO), i.e., if no staff member is present, the POS terminal 20 issues a notification of waiting for issuance when staff member is absent (see FIG. 11(B)) to prompt the staff member to issue an instruction slip (step S1508), and proceeds to step S1511. This notification can prompt the hall staff member or kitchen staff member to issue an instruction slip by displaying a notification image on the staff display unit 210 or outputting a notification sound.

On the other hand, if a store clerk is present in step S1507 (step S1507: YES), the POS terminal 20 determines whether a meal ticket purchase is in progress (step S1509). If a meal ticket purchase is not in progress (step S1509: NO), that is, for example, if a store clerk is logged in to perform maintenance or tallying in a situation where a customer is not present at the POS terminal 20, the POS terminal 20 proceeds to step S1513.

On the other hand, if the meal ticket purchase process is in progress (step S1509: YES), the POS terminal device 20 issues a notification of waiting for issuance during the meal ticket purchase procedure (see FIG. 17) to prompt the store clerk to issue an instruction slip after purchasing the meal ticket (step S1510). In this notification, a notification image is displayed on the store clerk display unit 210 to prompt the logged-in store clerk to issue an instruction slip.

The POS terminal 20 then displays an instruction slip issue button (see FIG. 17) on the store clerk display unit 210 to accept the issuance of an instruction slip (step S1511). The POS terminal 20 then determines whether the instruction slip issue button has been pressed (step S1512). The POS terminal 20 waits until the instruction slip issue button has been pressed (step S1512: NO), and when the instruction slip issue button has been pressed (step S1512: YES), the POS terminal 20 issues an instruction slip (step S1513).

If the current operating mode is the clerk registration mode (step S1506: YES), the POS terminal 20 issues an instruction slip (step S1513) without the need to press the instruction slip issue button or receive a notification that the instruction slip is waiting to be issued. The POS terminal 20 then issues an issued notification, using the clerk display unit 210 or the like, indicating that the instruction slip has been issued (step S1514), and ends the series of processes.

(Example of a screen displayed on the customer side display unit 205 of the POS terminal device 20 in the ticket vending machine mode)
Next, an example of a screen displayed on the customer display unit 205 of the POS terminal 20 in the ticket vending machine mode will be described with reference to Fig. 16. Fig. 16 is an explanatory diagram showing an example of a screen displayed on the customer display unit 205 of the POS terminal 20 in the ticket vending machine mode.

In FIG. 16, the ticket sales screen 1600 includes a product registration button 1601, a purchased product display area 1602, a price display area 1603, a receipt issue button 1604, a cancel button 1605, and a ticket issue button 1606.

The product registration button 1601 is a button that accepts the selection of a product that the customer wishes to purchase. For example, the customer presses the product registration button 1601 that corresponds to the product they wish to purchase. When the product registration button 1601 is pressed, the product is displayed in the purchased product display area 1602. The amount display area 1603 displays information about money, including the amount inserted, which indicates the amount inserted by the customer, the total amount of the products they wish to purchase, and the amount of change.

The receipt issue button 1604 is a button that accepts the issuance of a receipt. When the receipt issue button 1604 is pressed, a receipt is issued along with the meal ticket. The cancel button 1605 is a button that accepts the cancellation of the product selected by pressing the product registration button 1601. The ticket issue button 1606 is a button that confirms the purchase of the product selected by pressing the product registration button 1601 and accepts the issuance of a meal ticket.

(Example of a screen displayed on the store clerk display unit 210 of the POS terminal device 20 in the ticket vending machine mode)
Next, an example of an issuance waiting notification screen displayed on the store clerk display unit 210 of the POS terminal 20 according to embodiment 3 will be described with reference to Fig. 17. Fig. 17 is an explanatory diagram showing an example of an issuance waiting notification screen 1700 displayed on the store clerk display unit 210 of the POS terminal 20 in ticket vending machine mode.

The issuance waiting notification screen 1700 shows the screen displayed on the store clerk display unit 210 while purchasing a meal ticket in the ticket vending machine mode. The issuance waiting notification screen 1700 includes the ticket sales screen 1600, an issuance reminder notification 1701, and an instruction ticket issue button 1702.

The ticket sales screen 1600 is the same as the screen displayed on the customer display unit 205 in ticket vending machine mode shown in FIG. 16, i.e., it shows a mirrored screen. The issuance prompt notice 1702 indicates that the kitchen printer device 40 cannot issue an instruction ticket (e.g., that it is broken) and prompts the user to issue an instruction ticket after the meal ticket purchase process.

The instruction slip issue button 1702 accepts the issuance of an instruction slip. For example, even if the meal ticket purchase process in the ticket vending machine mode has not been completed, an instruction slip is issued when the instruction slip issue button 1702 is pressed. In other words, even during the meal ticket purchase process in the ticket vending machine mode, it is possible to issue an instruction slip in response to a store clerk's operation. However, if instruction slips were made available for issuance at the timing when meal tickets, receipts, and invoices are issued during the meal ticket purchase process (the timing of the settlement slip issuance process), there is a risk that these documents and instruction slips will be mixed up. For this reason, it may be possible to prevent instruction slips from being issued at the timing when these documents are issued.

Although not shown in the figure, the issuance waiting notification screen in the ticket vending machine mode when no store clerk is present can be a screen similar to the issuance waiting notification screen 1110 shown in FIG. 11 (B).

As described above, in the POS system 1400 of embodiment 3, the POS terminal device 20 distinguishes between operating modes including clerk registration mode and ticket machine mode, and issues an instruction slip based on the result of the distinction. This makes it possible to prevent an instruction slip from being issued in ticket machine mode, thereby preventing the clerk from forgetting to pick up the instruction slip. In addition, since an instruction slip can be issued in clerk registration mode, an instruction slip can be issued quickly and the clerk can properly understand the issuance.

In addition, in the ticket vending machine mode, the POS terminal device 20 of the third embodiment is further configured to issue an instruction slip based on the result of determining whether or not a store clerk is present. This allows an instruction slip to be issued even in the ticket vending machine mode if a store clerk is present. Therefore, in the ticket vending machine mode, an instruction slip can be issued quickly, and the store clerk can properly understand the issuance of the instruction slip.

In addition, the POS terminal device 20 of the third embodiment is further configured to issue an instruction slip when a store clerk is present, based on the result of determining whether or not the settlement process is in progress (meal ticket purchase process in progress). This makes it possible to prevent an instruction slip from being issued while the settlement process is in progress, even when a store clerk is present. This prevents the instruction slip from being mixed with other documents such as meal tickets, and makes it possible to issue the instruction slip appropriately.

(Modification of the third embodiment)
In the above-mentioned third embodiment, as shown in Fig. 15, if the current operating mode is the clerk registration mode (step S1506: YES), an instruction slip is issued without the need to press the instruction slip issue button or to be notified that an issuance is waiting (step S1513).In place of or in addition to this configuration, a modified example of the third embodiment will be described in which, even if the current operating mode is the clerk registration mode, the instruction slip issue button must be pressed or an issuance waiting notification must be sent if a settlement process is in progress.

In this modified example, if the current operating mode is the store clerk registration mode (step S1506: YES), the POS terminal device 20 determines whether or not the settlement process is in progress, and if the settlement process is in progress, issues a notification that the issuance is pending and proceeds to step S1511 (display of the instruction ticket issuance button).

According to this modified example, even in clerk registration mode, it is possible to prevent instruction slips from being issued during the settlement process. This prevents the mixing of settlement slips such as receipts with instruction slips, and allows instruction slips to be issued appropriately. Note that it is also possible to prevent instruction slips from being issued only when the settlement slip issuance process is being performed during the settlement process.

The embodiments will be summarized below.
TECHNICAL FIELD The present invention relates to a product sales data processing device and a program.
[Background technology]
Conventionally, eating and drinking establishments such as fast food restaurants and family restaurants use a system in which orders for products are received from customers using a point of sales (POS) terminal device or an order terminal device carried by a staff member, and the received order details are transmitted to a kitchen printer device. The kitchen printer device is placed in the kitchen and issues an instruction slip indicating cooking instructions. For example, the product, quantity, seat number, etc. are printed on the instruction slip. When the instruction slip is issued, the kitchen staff member starts cooking the order details indicated on the instruction slip. Then, when the cooking is completed, the instruction slip is handed over to a hall staff member together with the cooked food. The hall staff member serves the cooked food to the table with the seat number printed on the instruction slip.
However, sometimes a kitchen printer runs out of paper during business hours and is unable to print order slips. To address this issue, there is known an order entry device that, when a kitchen printer detects that it is out of paper, sends order information to another kitchen printer to print the order slips (see, for example, Japanese Patent Application Laid-Open No. 2003-233664).
[Prior art documents]
[Patent Documents]
[Patent Document 1] JP 2001-150762 A [Summary of the Invention]
[Problem to be solved by the invention]
However, in the conventional technology, if the kitchen printer is unable to output cooking instructions due to a malfunction or the like, outputting the cooking instructions on a POS terminal may hinder the operation of the POS terminal operator or the output cooking instructions may be difficult for the store clerk to understand, depending on the state of the POS terminal. For this reason, the conventional technology has the problem of being unable to output cooking instructions appropriately.
The present invention has been made in view of the above circumstances, and has an object to provide a technique that can suitably output cooking instructions.
[Means for solving the problems]

(1) In order to solve the above-mentioned problems, one aspect of the present invention is a product sales data processing device that is a product sales data processing system (POS system 1) that includes a cooking instruction output device (kitchen printer device 40) that outputs cooking instructions for ordered products, and a payment device (POS terminal device 20) that settles the payment for the products and outputs a payment slip indicating the settlement details, wherein the payment device is equipped with a discrimination means for discriminating the state of the payment device when it is impossible for the cooking instructions to be output by the cooking instruction output device, and an output control means for causing the payment device to output the cooking instructions based on the result of the state discrimination by the discrimination means.
According to the above configuration, the POS terminal 20 can issue an instruction slip at an appropriate timing according to the status of the device itself. Therefore, for example, if the kitchen printer 40 is unable to issue an instruction slip due to a malfunction or the like, even if the POS terminal 20 is caused to issue an instruction slip, it is possible to prevent the operation of the POS terminal 20 by the store clerk and the store clerk from being unable to understand the issued instruction slip. Therefore, the kitchen staff can start cooking appropriately, which prevents the time required to complete cooking from being taken up and therefore prevents customers from having to wait. As a result, the POS system 1 of the first embodiment can issue instruction slips appropriately.

(2) In the configuration of (1) above, the discrimination means may determine whether the state is a state in which a store clerk is present near the payment device, and the output control means may output the cooking instructions based on the result of the discrimination means' determination of the store clerk presence state.
According to the above configuration, since it is possible to prevent the issuance of an instruction slip when a store clerk is absent, it is possible to prevent the store clerk from forgetting to pick up the instruction slip. Also, since it is possible to issue an instruction slip when a store clerk is present, it is possible to issue an instruction slip quickly and to allow the store clerk to properly understand the issuance of the instruction slip.

(3) In the configuration of (2) above, when the discrimination means determines that the store clerk is present, it may further discriminate whether the store clerk is in a customer service operation state (payment processing in progress), which indicates that a store clerk is performing a customer service operation, and the output control means may output the cooking instructions based on the discrimination result of the discrimination means as to whether the store clerk is present and the discrimination result of the customer service operation state.
According to the above configuration, even if a store clerk is present, it is possible to prevent the issuance of an instruction slip during a customer service operation (payment processing). This prevents the mixing of payment slips such as receipts and instruction slips, and allows for the optimal issuance of instruction slips.

(4) In any of the configurations (1) to (3) above, an order terminal device (order terminal device 30) may be provided that accepts the ordered product, and the output control means may cause the order terminal device to output the cooking instructions for the product accepted.
According to the above configuration, the order terminal 30 can cause the POS terminal 20 to issue an instruction slip for a product for which an order has been accepted at an appropriate time.

(5) In the configuration of (1) above, the discrimination means may discriminate which of a plurality of operating modes the state is in, including a store clerk-assisted mode in which the purchasing procedure for the product is carried out with the intervention of a store clerk, and a self-operation mode in which the purchasing procedure for the product is carried out without the intervention of a store clerk, and the output control means may output the cooking instructions based on the result of the discrimination means' discrimination of the operating mode.
According to the above configuration, since the instruction slip is not issued in the ticket vending machine mode, it is possible to prevent the clerk from forgetting to pick up the instruction slip. Also, since the instruction slip can be issued in the clerk registration mode, the instruction slip can be issued quickly and the clerk can properly understand the issuance.

(6) In the configuration of (5) above, when the discrimination means determines that the mode is the self-service mode, it may further discriminate whether or not a store clerk is present near the payment device, and the output control means may output the cooking instructions based on the result of the discrimination means' discrimination of the operating mode and the result of the discrimination of the store clerk presence status.
According to the above configuration, even in the ticket vending machine mode, an instruction slip can be issued if a store clerk is present. Therefore, in the ticket vending machine mode, an instruction slip can be issued quickly, and the store clerk can properly understand the issuance of the instruction slip.

(7) In the configuration of (6) above, when the discrimination means determines that a waiter is present, it may further discriminate whether or not payment is being processed, and the output control means may output the cooking instructions based on the result of the discrimination means' determination of the waiter's presence status and the result of the discrimination means' determination that payment is being processed.
According to the above configuration, even if a store clerk is present, it is possible to prevent the issuance of an instruction slip during the settlement process. This prevents the instruction slip from being mixed with other documents such as meal tickets, and allows the instruction slip to be issued appropriately.

(8) In any of the configurations (1) to (7) above, the cooking device may further include a receiving unit that receives an instruction to start outputting the cooking instructions when the output control unit does not output the cooking instructions.
According to the above configuration, an instruction slip can be issued at a desired timing.

(9) In any of the configurations (1) to (8) above, a notification unit may be provided that notifies the user about the output of the cooking instruction by the output control unit.
According to the above configuration, it is possible to notify store clerks that an instruction slip has been issued or that it is waiting to be issued, so that the store clerks can easily know when an instruction slip has been issued or when an instruction slip has not yet been issued.

(10) In order to solve the above-mentioned problems, another aspect of the present invention is a program that causes a computer used in a settlement device of a product sales data processing system, which includes a cooking instruction output device that outputs cooking instructions for an ordered product, and a settlement device that settles the payment for the product and outputs a settlement slip indicating the settlement details, to function as a discrimination means that discriminates the status of the settlement device when it is impossible for the cooking instruction output device to output the cooking instructions, and an output control means that causes the settlement device to output the cooking instructions based on the result of the status discrimination by the discrimination means.
According to the above configuration, the POS terminal 20 can issue an instruction slip at an appropriate timing according to the status of the device itself. Therefore, for example, if the kitchen printer 40 is unable to issue an instruction slip due to a malfunction or the like, even if the POS terminal 20 is caused to issue an instruction slip, it is possible to prevent the operation of the POS terminal 20 by the store clerk and the store clerk from being unable to understand the issued instruction slip. Therefore, the kitchen staff can start cooking appropriately, which prevents the time required to complete cooking from being taken up and therefore prevents customers from having to wait. As a result, the POS system 1 of the first embodiment can issue instruction slips appropriately.

In the above explanation, the POS terminal device 20 is described as having a configuration including a settlement unit, a discrimination unit, an output control unit, a reception unit, and a notification unit, but all or some of these functional units may be provided in other computer devices. For example, all or some of these functional units may be provided in the order terminal device 30, the kitchen printer device 40, or other computer devices. Furthermore, the number of computer devices that are provided with these functional units is not limited to multiple, and may be one. For example, one computer device may have all of these functional units.
