Description

  The present invention relates to a payment machine, a sales information management device, a payment system, a payment method, and a program.

  2. Description of the Related Art In recent years, self-oiling machines for refueling gasoline and the like have been installed at refueling handling stations (self-type stands) where users can refuel themselves. There is a limitation in the space for newly installing an external machine on such a self-oiling machine. Therefore, as an external machine mounted on the self-fueling machine, a depositing machine capable of depositing only banknotes at the time of cash settlement is often connected.

  If a change occurs when purchasing goods (for example, gasoline) in cash using a self-service refueling machine equipped with a depositing machine that can only accept banknotes, the user can register at the cash register in the refueling office. The change is received, or the change paid out by a payment machine provided separately from the refueling machine is received. From the viewpoint of reducing capital investment costs, there are many cases in which the number of gasoline-settling machines that function exclusively for changing returns is smaller than the number of self-fueling machines for gasoline.

Also, in a refueling system comprising a plurality of self-fueling machines each having a payment machine for returning change, when the self-fueling machine reports an error of the change return function, it is designated by the POS controller that received the notification There has been considered an oil supply system that returns change using a self-fueling machine equipped with a settlement machine in normal operation (see, for example, Patent Document 1).

  In the following explanation example, the “settlement system” according to the first embodiment records the sales information of the product every time the product (for example, kerosene or gasoline) is sold, and the sales information is totalized to manage the sales. This is an example applied to a POS (Point Of Sales) system for self-stand.

  Further, the “settlement machine” according to the first embodiment is applied to the kerosene sales settlement machine 1 provided in the self-stand POS system.

  First, the configuration of the POS system for self-stand according to the first embodiment will be described.

  As shown in FIG. 1, the POS system for a self-stand according to the first embodiment includes a kerosene sale settlement machine 1, a kerosene self-ordering machine 20, and gasoline self-ordering machines 100-1, 100-2 and 100-3. (“Another device different from the settlement machine” and “sales apparatus”), a gasoline sales settlement machine 200, a sales information management apparatus 300, and a data line 400. The number of the kerosene sale settlement machines 1, the number of kerosene self-order machines 20, the number of gasoline self-order machines 100-1 to 3 and the number of gasoline sale settlement machines 200 may be arbitrary. Hereinafter, the gasoline self-ordering machines 100-1 to 100-3 are collectively referred to as a “gasoline self-ordering machine 100”.

  In the present embodiment, the kerosene sale settlement machine 1 can communicate with the kerosene self-ordering machine 20 and the sales information management device 300. The kerosene sales settlement machine 1, the gasoline self-ordering machines 100-1 to 3 and the gasoline sales settlement machine 200 are configured to be independent of each other and do not communicate directly with each other via the data line 400. To do.

  On the other hand, the gasoline self-ordering machines 100-1 to 100-3 and the gasoline sales settlement machine 200 are configured to be able to communicate with each other via the data line 400, and can be linked to each other and can also communicate with the sales information management device 300. It is.

  Hereinafter, each component 1, 20, 100, 200, 300 and 400 of the POS system for self-stand (settlement system) will be described.

  The kerosene sale settlement machine 1 has a plurality of functions (sales function, settlement function, etc.). The kerosene sales settlement machine 1 fulfills a function designated by the user among a plurality of functions (for example, a sales function and a settlement function).

  Hereinafter, information input from the outside in order to designate the kerosene sale settlement machine 1 to perform the settlement function is referred to as “settlement function designation information”. The form of the payment function designation information is not particularly limited.

  The kerosene sale settlement machine 1 provides the user with a sale service for selling kerosene in cooperation with the kerosene self-ordering machine 20 and returns the “first change” that is change at the time of kerosene sale. It is a “settlement machine” with a “sales function”. The kerosene sales settlement machine 1 operates so as to fulfill the sales function when the “settlement function designation information” described later is not transmitted from the kerosene self-ordering machine 20. Here, the kerosene self-ordering machine 20 has a function of issuing a slip (receipt) relating to a kerosene sales service transaction, and a function of transmitting various information described in the kerosene sales service slip to the sales information management device 300. Have

  On the other hand, when the “settlement function designation information” is input, the kerosene sales settlement machine 1 operates to fulfill the “settlement function”.

  The “settlement function” of the kerosene sales settlement machine 1 is a function for returning “second change” that is a change in the gasoline sales process of the gasoline self-ordering machine 100. The “settlement function” of the kerosene sales settlement machine 1 is the same as the settlement function of the gasoline sales settlement machine 200 described later, and will be described in detail later.

  Next, the kerosene self-ordering machine 20 will be described.

  The kerosene self-ordering machine 20 supplies kerosene through a fueling nozzle when a kerosene sale service is provided by the sale function of the kerosene sale settlement machine 1. The kerosene self-ordering machine 20 counts the amount of kerosene supplied from the start of kerosene sales to the present time (current sales quantity) by executing the “current sales amount counting process”. Further, the kerosene self-ordering machine 20 transmits a sale end signal to the kerosene sale settlement machine 1 when the sale of kerosene is finished.

  Next, the gasoline self-ordering machine 100 will be described.

  Each of the gasoline self-ordering machines 100-1 to 100-3 is a “sales device” that performs a gasoline sales process. In the following explanation example, each of the gasoline self-ordering machines 100-1 to 100-3 has only a deposit function for inserting cash, and has a function of returning change to a user who has purchased gasoline. Shall not.

  The gasoline sales function of the gasoline self-ordering machine 100 includes a function of issuing a slip (receipt) relating to a gasoline sales service transaction provided by the gasoline self-ordering machine 100. Each slip contains various information for uniquely identifying each transaction when selling gasoline.

  Below, each information described in the voucher issued by the gasoline self-ordering machine 100 will be described in detail.

  As shown in FIG. 2, the voucher issued by the gasoline self-ordering machine 100 includes, for example, the date and time of sale, the name of the product purchased by the user (gasoline) and the sales quantity, and the gasoline sales time. “Sales information” indicating an input amount, a gasoline sales amount (a purchase amount for the user), and a “second change amount” is described.

  Further, in this slip, a “slip number” for uniquely identifying the above-described sales information regarding each transaction sorted in slip units issued by the sales service is described. This “slip number” is a number generated by each gasoline self-ordering machine 100-1 to 100-3 and assigned to each transaction (slip issue unit).

  The “slip number” is, for example, a device identification number for identifying each of the gasoline self-fueling machines 100-1 to 100-3 and a transaction identification number assigned by each of the gasoline self-fueling machines 100-1 to 100-3. It is a number expressed in combination.

  For example, the device identification number assigned to the gasoline self-ordering machine 100-1 is “100-1”, and the transaction identification number generated and assigned to the transaction performed on the gasoline self-ordering machine 100-1 is If it is “0001”, the “slip number” corresponding to the transaction is “100-1-0001”.

  In addition, the transaction identification number is a number generated and assigned by a serial number for each transaction (issue of a slip) in each gasoline self-ordering machine 100-1 to 100-3. The transaction identification number is a number that is not duplicated in each of the gasoline self-ordering machines 100-1, 2 and 3. In this illustrative example, it is assumed that the transaction identification number once given by the gasoline self-ordering machine 100-1 is a number that is not given again by the gasoline self-ordering machine 100-1. The transaction identification number may be cleared to a predetermined value (for example, “0001”) every predetermined period (for example, 24 hours).

  Furthermore, a “code label” indicating code data (“first code data”) converted according to a predetermined format for representing a slip number is printed on the slip issued by the gasoline self-ordering machine 100. This “code label” is information generated and assigned by each gasoline self-fueling machine 100-1 to 100-3.

  The first code data described in the code label (data corresponding to the slip number converted into a predetermined format) and the slip number are uniquely associated with the sales information described above in the sales information management device 300 It is.

  Therefore, the sales information management device 300 can separate all transactions in each of the fuel dispensers 20 or 100 in the self-stand POS system based on either the first code data or the slip number.

  The format of the code label is arbitrary such as a barcode format or a QR code format. When the code label format is a bar code format, it may be a “JAN (Japanese Article Number) code” or an “OCR (Optical Character Recognition) code”. In the following explanation example, a case where the conversion format of “code label” is a barcode format and “code label” is barcode information which is barcode converted information will be described as an example.

  Further, the self-ordering machine for gasoline 100 is described in sales information (gasoline sales date and time, sales quantity, amount of money input at the time of sales, gasoline sales amount, second change amount, etc.), slip number, and code label. The generated code data (first code data) is transmitted to the sales information management apparatus 300 via the data line 400.

  Note that the sales information management device 300 is the information for associating the sales information transmitted from the gasoline self-ordering machine 100 with the slip number and the code data (first code data) shown in FIG. Information 305 "is stored.

  Next, a gasoline sales settlement machine 200 having the same “settlement function” as the kerosene sales settlement machine 1 will be described. The gasoline sales settlement machine 200 and the kerosene sales settlement machine 1 are independent from each other and are not linked to each other.

  The gasoline sales settlement machine 200 receives the input of the slip number issued by the gasoline self-ordering machines 100-1 to 100-3 through the gasoline sales service, and returns (settlement) the second change corresponding to the received slip number. It has a checkout function. Further, the gasoline sales settlement machine 200 can accept the input of the slip issued by the kerosene sales service issued by the kerosene self-ordering machine 20, and can return the first change corresponding to the accepted slip number. It is a thing.

  The slip number receiving method here is, for example, a receiving method in which barcode information (code label) described in a slip is read by a barcode reader.

  Further, for example, the gasoline sales settlement machine 200 accepts an input of a slip number corresponding to a touch panel or key operation performed by a user.

  The gasoline sales settlement machine 200 transmits the code data (data corresponding to the slip number) indicated by the read barcode or the input slip number to the sales information management device 300.

  The sales information management apparatus 300 acquires the amount of the second change corresponding to the slip number from the sales aggregation information 305 shown in FIG. 3, and stores “change amount information” indicating the amount of the acquired second change. It is transmitted to the gasoline sales settlement machine 200. The gasoline sales settlement machine 200 returns cash corresponding to the amount of the second change indicated by the change amount information received from the sales information management device 300.

  Here, the adjustment function of the gasoline sales settlement machine 200 has been described as an example, but this “settlement function” refers to the kerosene sales settlement machine 1 that is the “reading device” according to the embodiment of the present invention. The same applies to.

  The code data read by the kerosene sale settlement machine 1 is “second code data”.

  Next, the sales information management device 300 will be described in detail.

  The sales information management device 300 acquires the amount of the second change corresponding to the code data indicated by the code label, and transmits change amount information indicating the amount of the acquired second change.

  The sales information management apparatus 300 executes “sales information management processing” and manages sales information of sales products (kerosene and gasoline). For example, the sales information management device 300 includes the sales information transmitted from the gasoline self-ordering machine 100, the slip number for uniquely identifying the sales information, and the code data described in the barcode information (code label). (First code data) is received via the data line 400.

  Further, the sales information management apparatus 300 stores the sales information received from the gasoline self-ordering machine 100, the slip number, and the code data as sales total information 305 shown in FIG.

  Further, the sales information management device 300 receives the code data (“second code data”) described in the barcode information read by the kerosene sales settlement machine 1.

  The sales information management device 300 identifies the sales information corresponding to the code data (second code data) received from the sales summary information 305 stored therein, and stores the second sales information registered in the identified sales information. Get the amount of change.

  The sales information management device 300 transmits “change amount information” indicating the amount of the second change corresponding to the received slip number to the kerosene sale settlement machine 1 or the gasoline sale settlement machine 200. The kerosene sale settlement machine 1 or the gasoline sale settlement machine 200 returns cash corresponding to the amount of the second change indicated by the change amount information transmitted from the sales information management device 300.

  The data line 400 connects the kerosene sale settlement machine 1, the sales information management device 300, and the kerosene self-order machine 20 to each other.

  The data line 400 connects the gasoline self-ordering machines 100-1 to 100-3, the gasoline sales settlement machine 200, and the sales information management device 300.

  Next, the configuration of the kerosene sale settlement machine 1 will be described.

  As illustrated in FIG. 4, the kerosene sale settlement machine 1 includes a charge insertion port 2, a change return port 3, and a reading unit 12.

  The charge entry port 2 is an opening provided in the case of the kerosene sale settlement machine 1 for inputting a fee when a user of the sales service purchases a product to be sold in cash. In the following, the fee entered at the fee entry port 2 is referred to as the “input fee”.

  The change return port 3 returns change (cash equivalent to the amount obtained by subtracting the sales amount from the input fee inserted at the fee input port 2) to the user who purchased the product in cash by the sales service. 2 is a mouth provided in the case of the settlement machine 1 for kerosene sale.

  The reading unit 12 is configured by, for example, a barcode reader. The reading unit 15 executes the “reading process” when the “settlement function” is executed, and uses the “code label” described in the slip issued by the gasoline self-ordering machines 100-1 to 3 (sales device). “Code data” (slip number converted into a predetermined format) described in certain barcode information is read. The code data read by the reading unit 12 is “second code data”.

  The kerosene self-ordering machine 20 linked to the kerosene sale settlement machine 1 includes a fueling nozzle 21, a display unit 23, an input unit 24, a printing unit 25, and a card reading unit 26.

  The refueling nozzle 21 is a nozzle for a user who has charged a charging fee from the charging port 2 to supply kerosene supplied according to the sales amount. The oil supply nozzle 21 and the casing of the kerosene self-ordering machine 20 are connected by a flexible hose.

  The display unit 23 is composed of, for example, an LCD (liquid crystal) panel, and executes “display processing” to display arbitrary data.

  For example, the current amount of kerosene supplied through the refueling nozzle 21 (current sales quantity) and the like are displayed while the input amount, the kerosene sales amount, and the kerosene sales process are being executed.

  The display unit 23 may have a touch panel function that is an input device that can be directly operated by a user with a finger or the like. In this case, the display unit 23 serves as the input unit 24. Note that the operation method of the touch panel may be a general method (for example, a resistance film method).

  The input unit 24 includes, for example, keys and a touch panel. The input unit 24 executes “input processing”, receives information according to a user operation, and outputs the information to the control unit 22 described later. The input unit 24 may be a voice input device that recognizes a user's voice collected by a microphone and converts the recognized voice into character information.

  The input unit 24 receives, for example, designation of either a sales function or a settlement function that the user desires to use from among a plurality of functions of the kerosene sale settlement machine 1 and controls the designated function to the control unit 22. Output to. Here, when the settlement function is designated, the input unit 24 outputs the above-described settlement function designation information. Furthermore, when the adjustment function is designated by the input unit 24, the control unit 22 transmits the adjustment function designation information indicating that to the kerosene sale settlement machine 1.

  For example, the input unit 24 receives an input of a slip number when the settlement function is selected. In addition, the input unit 24 receives inputs such as the sales amount or sales quantity of kerosene desired by the user in the sales function, and the settlement method.

  The printing unit 25 is configured by a printer or the like. The printing unit 25 executes “print processing” and issues a slip relating to a transaction performed in a kerosene sales service of the sales unit 223 described later. The printing unit 25 prints sales information, a slip number and code data (barcode information) in a transaction at the time of kerosene sales, and issues a printed slip.

  The card reading unit 26 is composed of, for example, a card reader. The card reading unit 26 executes “card reading processing” and reads information recorded on the card held by the user. For example, when the sales function is specified by the input unit 24 and the payment method determining unit 113 determines that the payment method is a prepaid card, the card reading unit 26 records the prepaid card using the card reader. The information indicating the balance that can be used by the user is read.

  The kerosene sale settlement machine 1 and the kerosene self-order machine 20 perform a sales function by cooperating with each other. Therefore, the display unit 23, the input unit 24, the printing unit 25, and the card reading unit 26 included in the kerosene self-ordering machine 20 are not limited to the kerosene self-ordering machine 20, but are provided in the kerosene sales settlement machine 1. It may be.

  Next, the configuration of the kerosene sale settlement machine 1 will be described in detail.

  As shown in FIG. 5, the kerosene sales settlement machine 1 of the present embodiment includes a control unit 11, a deposit / withdrawal unit 13, and a communication unit 14 in addition to the reading unit 12 (barcode reader) illustrated in FIG. 4. And a bus 15.

  The control unit 11 executes “control processing” and controls the kerosene sale settlement machine 1 as a whole. For example, the control unit 11 performs a sales function-related process including the return of the first change when providing the kerosene sales service in cooperation with the kerosene self-ordering machine 20, and a settlement function for returning the second change. Process related to the settlement function.

  As shown in FIG. 6, the control unit 11 includes a designated function determination unit 111, a function switching unit 112, a first change settlement unit 113, and a second change amount request unit 114.

  The designated function discriminating unit 111 executes “designated function discriminating process”, and discriminates the function designated by the user at the input unit 24 of the kerosene self-ordering machine 20.

  More specifically, the designated function determination unit 111 determines whether or not the “settlement function designation information” is output from the kerosene self-ordering machine 20 (that is, “whether or not the settlement function designation information is input to the input unit 24”). ) To determine whether the function designated by the input unit 24 is “sales function” or “settlement function”. The designated function determination unit 111 determines that the payment function is specified when “settlement function specification information” is input, and determines that the sales function is specified when it is not input.

  The “sales function” here is a function of providing a kerosene sales service, a function of issuing a voucher when selling kerosene, and a “first change” for a kerosene purchaser in cooperation with the self-ordering machine 20 for kerosene. A return function is included. In addition, the first change return function is a function that allows a user who has purchased kerosene in cash at the kerosene sales service to receive cash equivalent to the amount of money charged at the charge slot 2 minus the sales amount. This is a function for returning from the change return port 3.

  On the other hand, in the “settlement function”, the code data indicated by the barcode information of the slip issued by the gasoline self-ordering machine 100 that sells gasoline is read, and the second change amount corresponding to the read code data is sold. Received from the information management apparatus 300. Then, the cash corresponding to the amount of the received second change is returned from the change return port 3.

  The function switching unit 112 executes “function switching processing”, and replaces the currently used function with a function (either sales function or settlement function) according to the result determined by the designated function determining unit 111. The control program executed by the control unit 11 is switched so as to be executed.

  Here, the “control program” is, for example, a program for a sales function that causes the kerosene sale settlement machine 1 to function as a “kerosene self-selling machine”, and the kerosene sale settlement machine 1 to be used as a “gasoline for change change”. It is a program for the checkout function that allows it to function as a “sale checkout machine”.

  The first change settlement unit 113 executes the “first change settlement process” when a “sales end signal” to be described later is transmitted from the kerosene self-ordering machine 20, and is provided by the kerosene self-ordering machine 20. The amount to be returned as the first change in the kerosene sales service is directly calculated (settled) without going through the sales information management device 300. For example, the first change settlement unit 113 obtains the amount of the first change by subtracting the sales amount of kerosene from the input amount. In this illustrative example, the kerosene self-ordering machine 20 transmits information indicating the amount of kerosene sales to the kerosene sales settlement machine 1.

  At this time, when a cash settlement signal is transmitted from the kerosene self-ordering machine 20, the deposit / withdrawal unit 13 returns cash corresponding to the amount of the first change determined by the first change settlement unit 113.

  The second change amount request unit 114 executes “second change amount request processing” in the “settlement function”, and the second change amount corresponding to the code data (second code data) read by the reading unit 12. Is notified to the sales information management device 300.

  The communication unit 14 receives “change amount information” indicating the amount of the second change acquired by the sales information management device 300 in response to the request of the second change amount request unit 114 from the sales information management device 300. .

  The deposit / withdrawal unit 13 illustrated in FIG. 5 includes, for example, a cash transport mechanism for transporting cash (banknotes and coins), and executes “payment / withdrawal processing”.

  In this “payment / withdrawal process”, the deposit / withdrawal unit 13 transports and stores the cash inserted at the charge slot 2.

  Further, the deposit / withdrawal unit 13 returns cash corresponding to the amount of the second change indicated by the change amount information transmitted from the sales information management device 300 in the settlement function.

  Further, the deposit / withdrawal unit 13 uses the kerosene sales function to send the first change (banknote or coin) corresponding to the amount of the first change calculated by the first change settlement unit 113 through the change return port 3. return.

  The communication unit 14 includes, for example, a communication module, executes “communication processing”, and communicates with the sales information management device 300 and the kerosene self-ordering machine 20 via the data line 400. In this illustrative example, the communication unit 14 does not communicate with the gasoline self-ordering machines 100-1 to 100-3 and the gasoline sales settlement machine 200.

  The communication unit 14, which is a “transmission unit”, executes “transmission processing”, for example, the barcode information of the gasoline self-ordering machines 100-1 to 100-3 read by the reading unit 12 with respect to the sales information management device 300. A “change change request signal” is transmitted to request notification of the amount of the second change corresponding to the code data indicated by.

  In addition, the communication unit 14 receives change amount information transmitted from the sales information management device 300 in response to the change notification request signal.

Based on the presence or absence, it is determined whether the function designated by the user is the “sales function” or the “settlement function”.

  When the settlement function designation information is transmitted from the communication unit 28 (when the settlement function designation information is designated by the input unit 24), it is determined that the designated function is the “settlement function”. When the settlement function designation information is not transmitted from the communication unit 28, it is determined that the designated function is a “sales function”.

  The function switching unit 112 executes “function switching processing (step S12)”, and performs control to realize a function (either “sales function” or “settlement function”) corresponding to the determination result of the designated function determination unit 111. Switch to the program.

  In this “function switching process”, when the designated function determination unit 111 determines that “sales function” is specified, the control program switches to a control program that realizes “sales function”. When the designated function determining unit 111 determines that the “settlement function” is designated, the control program switches to a control program that realizes the “settlement function”.

  After switching of the control program for realizing each function by the function switching unit 112, each component included in the control unit 11 executes a process according to the switched control program, and executes a process related to the “sales function”. The “related processing (step S13)” or “settlement function related processing (step S14)” which is processing related to the “settlement function” is executed. This completes a series of function switching operations.

  Next, the above-described “sales function related process (step S13)” and “settlement function related process (step S14)” will be described in detail.

  First, the “sales function related process (step S13)” will be described. This “sales function related process” is an operation when the designated function determination unit 111 determines that “sales function” is selected, and the function switching unit 112 switches to a control program that realizes the “sales function”.

  In the “sales function-related processing”, first, various processes for providing a sales service are performed by the kerosene self-ordering machine 20.

  The display unit 23 of the kerosene self-ordering machine 20 executes “display processing” and prompts the user to designate “settlement method” and “sales quantity” (in this example, the amount of oil supply or the sales price). Display a message.

  Subsequently, the input unit 24 executes “input processing”, receives inputs of “settlement method” designated by the user and “sales quantity” designated by the user, and outputs them to the control unit 22.

  The settlement method determination unit 221 of the kerosene self-ordering machine 20 executes “settlement method determination processing”, and the settlement methods input by the input unit 24 are “cash payment”, “prepaid card”, and “credit card”. To determine which payment method is used.

  The sales quantity identification unit 222 executes “sales quantity identification processing”, and in the payment method determined by the payment method determination unit 211, the sales quantity (or sales amount) desired by the user input at the input unit 24 ).

  The series of “display processing”, “settlement method determination processing”, and “sales quantity identification processing” may be performed by the kerosene sales settlement machine 1.

  When the settlement method determination unit 221 determines that the settlement method is “cash”, the communication unit 28 transmits a cash settlement signal to the kerosene sale settlement machine 1.

  As shown in FIG. 12, the communication unit 14 (reception unit) of the kerosene sale settlement machine 1 executes “reception processing (step S21)” and receives the cash settlement signal transmitted from the kerosene self-ordering machine 20. Receive.

  In addition, the display unit 23 of the kerosene self-ordering machine 20 executes a “display process” and displays a message prompting the user to insert a charge into the charge input port 2 of the kerosene sale settlement machine 1. Instead of displaying the message, “voice output processing” by the voice output unit 27 may be executed, and voice guidance prompting the user to insert a fee into the fee input port 2 may be emitted.
