TECHNICAL FIELD The present invention relates to a cafeteria management device in a cafeteria system for providing food by inserting a card for identifying an individual into a card reader.

(B) Conventional technology As a cafeteria system, for example, a system of a company, a school, etc. as disclosed in Japanese Patent Laid-Open No. 63-316261 is known, and a user uses a card reader to identify a card for identifying an individual. You can receive food by throwing it in.

In such a cafeteria system, a ticket vending machine generally issues a meal ticket to a person who does not have a card so that the person can receive the food in exchange for the meal ticket.

(C) Problems to be Solved by the Invention However, a meal voucher for a favorite dish is purchased by a ticket vending machine and the dish is received in exchange for the meal voucher, or a card for identifying an individual is inserted into a card reader to receive the dish. In the cafeteria system, the card reader is located at the food receiving place, so when the card is inserted, the food can be received almost at the same time as the card is inserted, but in the case of a meal ticket, the ticket vending machine and the food receiving place. Since it is generally placed apart from, there is a time delay between the purchase of a meal ticket and the receipt of food.
Then, if there is a time lag in receiving the food by the two purchasing methods, there are the following problems.

That is, when the number of dishes is limited, the person who has the card inserts the card into the card reader and receives the last dish while the customer who bought the meal ticket at the ticket vending machine goes to the place where the dish is received. Then, at this point, the ticket vending machine stops issuing tickets for this dish, but there is a problem that the dish cannot be provided to the customer who purchased the meal ticket immediately before that.

Accordingly, the present invention provides a controller for centrally managing the ticket vending machine and the card reader, manages the inventory of food with this controller, and controls the ticket vending machine and the card reader according to the situation. A device is provided.

(D) Means for Solving the Problems In order to solve the above problems, the cafeteria management device according to the present invention includes a controller connected to a ticket vending machine and a card reader by a bus line method, and the ticket vending machine includes , The sales information about the food that can be exchanged for the ticket by selling the ticket is sent to the controller, and when the controller indicates that the food is sold out, sales control means for stopping the ticket sales is provided. Reading control means for sending sales information about food provided to a person holding the card to the controller by inserting a valid card, and stopping reading the card when the controller indicates that the food is sold out The controller is provided with storage means for storing a preset number of dishes that can be provided, and the sales amount. Indicates that the food is sold out to the calculation means for calculating the number of dishes provided based on the information and the ticket vending machine and the card reader when the number of dishes provided reaches the preset number of dishes And a control means.

(E) Action The controller stores the preset number of dishes that can be provided in the storage means. Then, when the ticket vending machine or the card reader outputs a food provision signal to the controller by issuing a ticket or inserting a card into the card reader, the controller calculates the number of dishes provided by the calculating means.

When the number of dishes provided has reached the preset number of dishes that can be provided, the controller indicates to the ticket vending machine and the card reader that the dishes are sold out. As a result, the sale control means of the ticket vending machine stops the sale of tickets, and the reading control means of the card reader does not read from the card even if the card is inserted.

And a coin dispensing unit 15B for dispensing change coins. The currency payout unit 15B is provided with a sensor for detecting the presence or absence of change currency.

The selection device 16 includes a plurality of selection switches 16 _{1 to} 16n for selecting the type of ticket, and when the selection switch is operated by the customer, the CPU 1 outputs the selection data indicating the selected ticket type.
Output to.

When the ticket issuing device 17 receives a ticket issuing signal from the CPU 10,
A ticket of the type indicated by this signal is issued from the issuing port 21.

The display device 18 includes an amount display device 19, a change-out display device 20, and a plurality of salable indicators L ₁ to ₁ according to the number of meal tickets to be sold.
Includes Ln and sold-out indicators E ₁ -En.

And in RAM 12, at least 4 as shown in FIG.
Street storage areas are formed. The storage area 12a is an area for storing each selling price for the menu of the meal ticket issued by the operation of each selection switch 16 _{1 to} 16n,
It includes n addresses corresponding to the number of selection switches 16 _{1 to} 16 n. The memory area 12b also includes n addresses and stores the menu code for each of the selection switches 16 _{1 to} 16 n. Each bit of the n-bit storage area 12c has a corresponding selection switch 16 _{1 to} 16 16.
It corresponds to n, and this storage area 12c is "sold out" for each menu by 1 bit "1" or "0".
Or the sold-out data indicating "not sold out" is loaded. The storage area 12d stores the terminal code of the vending machine.

FIG. 6 is a flow chart showing the operation of the sale process performed by the CPU 10 of the sale control means 1A in accordance with the program stored in the ROM 11, and in the sale stand-by state before the money is put into the ticket vending machine, Based on the sold-out data stored in the storage area 12c, a control signal is given to the display device 18 to control the drive of the sold-out indicators E _{1 to} En. Further, in the sale standby state, the CPU 10 inputs a detection signal of a sensor for detecting the presence or absence of change currency from the money dispensing unit 15B, and a change-out indicator of the display device 18 according to the presence or absence of change indicated by the signal. Control the drive of 20.

When money is thrown into the ticket vending machine, the CPU 10 determines whether all the ticket types are sold out based on the sold-out data, and in the case of sold-out, the change money signal is sent to the money payout unit 15B of the money processing device 15. Control the return of input money by giving.

However, if there is at least one type of ticket that is not sold out, the CPU 10 reads the input currency signal from the currency detection unit 15A, calculates the input amount based on the signal, and stores it in the input amount buffer. Amount display
Controls 19 to display the input amount. And CPU10 is RAM
Read the selling price for each ticket type stored in the 12 storage areas 12a, compare the input price with the selling price, and sell at this input amount according to the presence or absence of change and the sold-out data. Determine the type of ticket that can be sold, create 1-bit "1" or "0" for each ticket type to indicate that it is "sellable" or "not sellable" and store it in the sellable data buffer. To do. Further, the CPU 10 uses the sellable data to display the sellable indicator of the display device 18.
Controls the drive of L _{1 to} Ln. Next, the CPU 10 determines whether it is a mode in which none of the ticket types can be purchased even though the input amount is equal to or higher than all the selling prices. This is the case where even if the maximum amount of money that is more than all the selling prices is put into the ticket vending machine, none of the products can be purchased due to the sold-out menu or lack of change. Is. When detecting such a mode, the CPU 10 causes the money payout unit 15B of the money handling apparatus 15 to operate.
The change money signal is given to and the return of the input amount is controlled.

When the CPU 10 determines that the mode is not the above mode in which neither food ticket can be purchased, the CPU 10 next determines whether the selection switches 16 _{1 to} 16 n have been operated. When the customer operates the selection switches 16 _{1 to} 16n, and the selection device 16 outputs the selection data by this, the CPU 10 checks whether the selected ticket type is available for sale by collating with the sale possible data. If the selected ticket type is available for sale, CPU10
Gives a ticket issuing signal to the ticket issuing device 17 to control the issuing operation of the selected ticket type. However, the customer selects the switch 16 ₁ to 1
If 6n is not operated, or if the selected ticket type is not available for sale even if it is operated, the process returns to the step of determining whether money has been inserted into the ticket vending machine. In this case, it is determined whether or not additional money has been inserted, and if there is no additional money, the CPU 10 determines whether the amount stored in the input amount buffer is "0" yen. As a result, the CPU10
It is possible to determine whether the current state is the money operation mode and the sales operation mode. Then, in the sales operation mode, the process proceeds to the step of determining whether the selection switches 16 _{1 to} 16 n have been operated. On the other hand, when there is additional input of money, the CPU 10 calculates and displays a new input amount of money and drives the salable indicators L _{1 to} Ln based on this amount of money, and the input amount of money is equal to or more than all the selling prices. Regardless, it is determined whether or not any of the ticket types is in the purchase-disabled mode, and then the process proceeds to the step of determining whether the selection switches 16 _{1 to} 16 n have been operated.

When the ticket issuing operation is performed, the CPU 10 creates a transaction message including a menu code indicating a dish that can be exchanged for the issued ticket, a selling price, and a terminal code, and transmits it as sales information to the controller 4 via the transmission control unit 13. . The controller 4 calculates the stock quantity of the corresponding menu by this transaction message, and then transmits a message indicating the sold-out status for all menus to the CPU 10. For example, if there are 32 kinds of meal tickets corresponding to the selection switches 16 _{1 to} 16n, the controller 4 sets “out of stock” or “not sold out” for each menu in 32 kinds of bits of 4-byte data. It is represented by 1-bit "1" or "0". This makes CPU10
Loads the received data into the storage area 12c as sold-out data. Therefore, the CPU 10 controls the sale of the meal ticket based on this new sold-out data.

FIG. 7 is a block diagram showing the configuration of the card reader 2,
The reading control means 2A includes a CPU 25, a ROM 26 storing a program for operation, a RAM 27, a transmission control unit 28, and an I / O.

A reading unit 30 and an indicator drive circuit 31 are connected to the interface 29, and the CPU 10 controls these devices based on a program stored in the ROM 26. RAM2
Reference numeral 7 stores a menu code of dishes to be sold at the window where the card reader 2 is arranged and a terminal code of the card reader 2.

FIG. 8 is a flowchart showing the operation of the registration processing performed by the CPU 25 of the reading control means 2A according to the program stored in the ROM 26. First, the CPU 25 causes the reading unit 30 to read the information of the card running in the running groove 17. To read.
Then, when the reading unit 30 reads the card information of the input card, a card inquiry message is created based on this card information and transmitted to the controller 4. Then, when the response message is received from the controller 4 and the content of the message at this time indicates that the card is permitted to be used, the CPU 25 controls the indicator drive circuit 31 to drive the OK indicator N1 and also to the RAM 27. A transaction message consisting of the stored menu code and terminal code and the ID code recorded on the insertion card is created and transmitted to the controller 4 as sales information.

The controller 4 is similar to the case of the ticket vending machine described above,
After calculating the stock quantity of the corresponding menu by the transaction message from the card reader 2, a message indicating the sold-out status of all the menus is transmitted to the CPU 25.

When the CPU 25 receives the response message, the CPU 25 determines whether the menu corresponding to the card reader 2 is sold out, and if not, waits for the next card to be inserted. However, when the CPU 25 detects that the corresponding menu is sold out, it goes into the sale stop mode,
In this mode, the card information is not read even if the card is inserted. Further, if the content of the response message from the controller 4 to the inquiry message of the card indicates that the use of the card is invalid, the CPU 25 controls the indicator drive circuit 31 to drive the NG indicator N2, and then the next card. Waits for to be input.

FIG. 9 is a block diagram showing the configuration of the controller 4 CP
U40, ROM41, RAM42, transmission control unit 43, CPU40,
The magnetic disk device 44 and the clock circuit 45 are connected. Then, the CPU 40 performs data transmission processing with the ticket vending machine 1 and the card reader 2 via the transmission control unit 43 based on the program stored in the ROM 41, and controls the magnetic disk device 44 having various files. .

As shown in FIG. 10, the magnetic disk device 50 is provided with a card file 51, a management file 52, and a sales registration file 53. The card file 51 has four storage areas A1 to A4. For each user of this cafeteria, the ID mark, company code, department code, and ID code recorded on the card possessed by each canteen are stored. Is stored. Then, the data of these card files 51 is written to the disk 6 set in the controller 4 by the personal computer 5. In addition, the management file 52 has an area M1 for storing the number of stocks for each menu in this cafeteria and an area M2 for storing the selling price. The corresponding initial stock quantity is written on the disk 6 by the personal computer 5. The sales registration file 53 includes a menu code storage area F1, an ID code storage area F2, a sales price storage area F3, a terminal code storage area F4, and a sales time data storage area F5.

FIG. 11 is a flowchart showing the processing operation performed by the CPU 40 according to the program stored in the ROM 41. Upon receiving the message, the CPU 40 determines whether the message is a card inquiry message. Then, in the case of a card inquiry, the inquired card is retrieved from the card file 51 of the magnetic disk device 50, a message indicating the result is created, and is transmitted to the inquired card reader 2.

When the CPU 40 determines that the received message is a transaction message, the CPU 40 writes various transaction data shown in the message to the sales registration file 53 and sells the time data shown by the clock circuit 45. Write to the registration file 53. At this time, in the message from the ticket vending machine 1, the selling price is shown together with the menu code. In this case, the CPU 40 compares the selling price with the selling price stored in the management file 52 for the corresponding menu, and then determines the selling price. Write in the sales registration file 53. Also, the sales price is not shown in the message from the card reader 2, and the CPU40
Reads the sales price stored in the management file 52 for the corresponding menu and sells the registration file 53.
Write in.

Then, the CPU 40 subtracts the sold quantity from the stock quantity stored in the stock quantity management file 52 of the magnetic disk device 50 with respect to the transmitted menu code, and outputs a transmission status indicating the sold-out status of all menus showing the result. Sentence CP
Transmit to U10 and CPU40.

As a result, since the sold-out status of all menus is transmitted to the ticket vending machine 1 and the card reader 2 in real time, a time difference between the ticket vending machine 1 and the card reader 2 at the time of sale is prevented, and the cooking There is no mistake in sales.

Further, the sales registration file 53 created by the controller 4 is processed into business management information by the personal computer 5. Further, the personal computer 5 extracts only the sales for which the ID code is recorded from the data of the sales registration file 53, and creates a credit file necessary for the subsequent billing process.
