Description

  The present invention relates to an order management system, a control device, and a slip printing control method used in the restaurant industry and the like.

  In the restaurant industry such as family restaurants and taverns, an order management system is introduced. In the order management system, when a clerk in charge of customer service inputs a customer order to the handy terminal, the handy terminal transmits the input order contents to the controller by radio. The controller transmits print data for printing the received order contents slip (cooking slip) to the printer. The printer prints the print data received from the controller, and the kitchen staff confirms the order contents with the printed slip and cooks the ordered food.

  In a printer that prints a slip, it takes time to complete printing after receiving print data. Therefore, even if the transmission of the print data from the controller is completed normally, if the printer power is interrupted for some reason until the printing is completed, the received print data will disappear and the slip cannot be printed. The kitchen staff may not be able to cook the food ordered.

  As a countermeasure, for example, the printer may hold the received print data in a memory with data backup so that the print data does not disappear even when the power is turned off. When the power is turned on again, the printer reads and prints the print data held in the memory. However, if the print data includes image data of handwritten characters or logo marks, the amount of print data increases. Therefore, a large-capacity nonvolatile memory is required for backup, and the cost of the printer is increased.

  Therefore, in Patent Document 1, when the printer of the order management system cannot print the print data due to power interruption or the like, the controller requests the controller to resend the print data when the power is turned on again. The print data resent from the controller is printed.

JP 2007-102331 A

  In Patent Literature 1, the controller adds data specifying information for specifying print data, for example, a slip number to the print data and transmits it to the printer. When the printer receives the print data of the slip, the printer stores the data specifying information added to the print data in the memory with data backup, and deletes it from the memory after the printing is completed. When the printer power is turned off before printing of the print data is completed and the printer is turned on again and can be connected to the controller, the printer issues a recovery print request command that sets the data identification information stored in the memory. Send to. The controller retransmits the print data specified by the data specifying information set in the recovery print request command to the printer. Thus, since it is not necessary to provide the printer with a nonvolatile memory having a large memory capacity, it is possible to reduce the cost of the printer and prevent a slip that is not printed due to a power interruption.

  However, when there are a plurality of print data to be transmitted, the normal controller performs transmission in the order of generation of print data transmission triggers. Therefore, the controller prints the slip print data that could not be transmitted before the print data retransmission request (recovery print request command) was received after the printer power failure occurred before the print data requested to be retransmitted. May be sent to the printer.

  For example, as shown in FIG. 33, when the handy terminal transmits order 1 to the controller, the controller transmits slip 1 print data for printing the slip of order 1 to the printer. The printer returns a receipt response for the slip 1 print data and prints the slip 1. Further, when the handy terminal transmits order 2 and order 3 to the controller, the controller transmits slip 2 print data and slip 3 print data for printing the slips of order 2 and order 3 to the printer. Even if the power is cut off before the printing of slip 2 is completed after the printer returns the reception response to the controller, order 4 and order 5 are further sent from the handy terminal to the controller. 5 generates slip 4 print data and slip 5 print data. However, even if the controller 4 transmits the slip 4 print data to the printer, the reception response is not returned, so the slip 4 print data is retransmitted repeatedly.

  When the power of the printer is turned on again, the printer transmits a connection request to the controller, and transmits a slip 2 print data and a resend request for the slip 3 print data, which have been detected that printing has not been completed, to the controller. However, when the controller returns a response to the connection request, the slip 4 print data and the slip 5 print data are transmitted to the printer, and then the slip 2 print data and the slip 3 print data requested to be retransmitted. May be sent. As a result, the printer prints the slips for the order 4 and the order 5 that are generated later before the slips for the order 2 and the order 3 that are generated earlier. As a result, in the kitchen, cooking is not performed in the order of the order, and the customer who has received the order later may provide the food earlier than the customer who has received the order earlier.

  The present invention has been made in consideration of such circumstances, and it is not necessary to mount a large-capacity nonvolatile memory in the printer, and even when the printer power is cut off, the slips are arranged in the order in which the orders are generated.

FIG. 4 is a sequence diagram of the order management system when the printer 30 prints different objects.
In the figure, the print request receiving unit 220 of the controller 20 is in a print request waiting state (step S102). When the print request receiving unit 220 receives a print request from another device via the first transmission / reception unit 21 (step S104), it determines whether the requested print target is a slip (step S106).
When the print request receiving unit 220 determines that the requested print target is a slip (step S106: YES), the slip processing unit 222 assigns a slip number and an identification code, and prints the slip print data based on the order data. Generate (step S108). Here, the slip processing unit 222 generates slip 1 print data that is slip print data of the slip 1.
The second transmitting / receiving unit 24 transmits the slip 1 print data generated by the slip processing unit 222 and the slip 1 identification code “0123”, which is an identification code assigned to the slip 1 print data, to the printer 30 (step S110).

  When the communication processing unit 321 of the printer 30 receives the slip 1 print data and the slip 1 identification code from the controller 20 via the transmission / reception unit 31 (step S112), the received slip 1 print data, slip 1 identification code, storage request, Is output to the storage processing unit 322 (step S114).

The registration unit 324 of the storage processing unit 322 writes the slip 1 print data and the slip 1 identification code in the volatile memory 33 in association with each other. In addition, the registration unit 324 writes the slip 1 identification code in the nonvolatile memory 34 because the slip 1 identification code does not match the non-target identification code “0000” stored in the nonvolatile memory 34 (step S116). The registration unit 324 notifies the communication processing unit 321 of the end of writing, and the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a response to the controller 20 (step S118).
The transmission / reception unit 31 transmits a receipt response of the slip 1 print data to the controller 20 (step S120).

  When the print request reception unit 220 of the controller 20 receives the receipt response of the slip 1 print data via the second transmission / reception unit 24, the print request reception unit 220 returns to step S102 and again enters the print request reception wait state. On the other hand, the registration unit 324 of the printer 30 outputs a print request in which the slip 1 identification code is set to the print processing unit 323 (step S122). The print processing unit 323 reads the slip 1 print data specified by the slip 1 identification code set in the print request from the volatile memory 33, and causes the print unit 35 to print the slip 1 print data (step S124).

After returning to the print request waiting state, the print request receiving unit 220 of the controller 20 receives the print request again (step S104). When the print request receiving unit 220 determines that the requested print target is a menu sheet and not a slip (step S106: NO), the print data generating unit 224 generates menu sheet print data and slip print data An identification code “0000” indicating that it is not is assigned (step S126).
The second transmission / reception unit 24 transmits the menu sheet print data generated by the print data generation unit 224 and the assigned identification code to the printer 30 (step S128).

  When the communication processing unit 321 of the printer 30 receives the menu sheet print data and the identification code from the controller 20 via the transmission / reception unit 31 (step S130), the received menu sheet, the identification code, and the storage request are stored in the storage processing unit 322. Output (step S132).

The registration unit 324 of the storage processing unit 322 writes the menu sheet print data and the identification code in association with each other and writes them in the volatile memory 33, but the identification code matches the unidentified identification code “0000” stored in the nonvolatile memory 34. Writing to the nonvolatile memory 34 is not performed (step S134). The registration unit 324 notifies the communication processing unit 321 of the end of writing, and the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a response to the controller 20 (step S136).
The transmission / reception unit 31 transmits a reception response of the menu sheet print data to the controller 20 (step S138).

  When the print request reception unit 220 of the controller 20 receives the reception response of the menu sheet print data via the second transmission / reception unit 24, the process returns to step S102 and again enters the print request reception wait state. On the other hand, the registration unit 324 of the printer 30 outputs a print request for menu sheet print data to the print processing unit 323 (step S140). The print processing unit 323 causes the menu unit print data to be printed on the printing unit 35 (step S142).

FIG. 5 is a sequence diagram of the order management system when the printing of the slip is normally completed after the printer 30 is turned on (not shown).
In the figure, when the printer 30 is powered on (step S201), the communication processing unit 321 of the processing unit 32 determines whether an identification code is stored in the nonvolatile memory 34. Since the identification code is not stored in the nonvolatile memory 34, the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a connection request (step S202). The transmission / reception unit 31 transmits a connection request to the controller 20 (step S204).
When the second transmission / reception unit 24 of the controller 20 receives the connection request and recognizes the activation of the printer 30, it returns a connection response to the printer 30 (step S206).

  The controller 20 receives the order data from the handy terminal 10 and transmits the slip 1 print data, which is the slip print data of the slip 1, and the slip 1 identification code “0001” to the printer 30 (step S208).

  The printer 30 executes the processes of steps S112 to S124 shown in FIG. 4 for the received slip 1 print data and slip 1 identification code (steps S210 to S222). That is, the communication processing unit 321 of the printer 30 receives the slip 1 print data and the slip 1 identification code via the transmission / reception unit 31, and outputs them together with the save request to the storage processing unit 322.

  The registration unit 324 of the storage processing unit 322 writes the slip 1 print data and the slip 1 identification code in association with each other in the volatile memory 33 and writes the slip 1 identification code in the nonvolatile memory 34. Is received to the controller 20. The registration unit 324 outputs a print request in which the slip 1 identification code is set to the print processing unit 323, and the print processing unit 323 causes the printing unit 35 to print the slip 1 print data.

  After receiving the receipt response of the slip 1 print data, the controller 20 further receives order data from the handy terminal 10 and receives the slip 2 print data as the slip print data of the slip 2 and the identification code of the slip 2 print data 2 The slip 2 identification code “0002” is transmitted to the printer 30 (step S224).

  The printer 30 executes the processing of steps S112 to S122 shown in FIG. 4 for the received slip 2 print data and slip 2 identification code (steps S226 to S236). In other words, the communication processing unit 321 of the printer 30 receives the slip 2 print data and the slip 2 identification code via the transmission / reception unit 31 and outputs them to the storage processing unit 322 together with the save request.

  The registration unit 324 of the storage processing unit 322 writes the slip 2 print data and the slip 2 identification code in association with each other in the volatile memory 33 and writes the slip 2 identification code in the nonvolatile memory 34. Is received to the controller 20. The registration unit 324 outputs a print request in which the slip 2 identification code is set to the print processing unit 323. The print processing unit 323 stores (buffers) the received print request because the print processing of the slip 1 print data has not been completed.

FIG. 6 is a sequence diagram continued from FIG. The processing in steps S222 and S236 in the figure represents the processing in steps S222 and S236 in FIG.
After receiving the receipt response of the slip 2 print data, the controller 20 further receives order data from the handy terminal 10 and uses the slip 3 print data which is the slip print data of the slip 3 and the identification code of the slip 3 print data. A slip 3 identification code “0003” is transmitted to the printer 30 (step S252).

  The printer 30 executes the processing of steps S112 to S120 shown in FIG. 4 for the received slip 3 print data and slip 3 identification code (steps S254 to S262). That is, the communication processing unit 321 of the printer 30 receives the slip 3 print data and the slip 3 identification code via the transmission / reception unit 31, and outputs them to the storage processing unit 322 together with the save request.

  The registration unit 324 of the storage processing unit 322 writes the slip 3 print data and the slip 3 identification code in association with each other in the volatile memory 33 and writes the slip 3 identification code in the nonvolatile memory 34. Is received to the controller 20.

  When the printing unit 35 of the printer 30 completes printing of the slip 1 print data, the print processing unit 323 of the printer 30 outputs a print completion response of the slip 1 print data to the storage processing unit 322 (step S264). The deletion unit 325 of the storage processing unit 322 deletes the slip 1 print data and the slip 1 identification code from the volatile memory 33 and also deletes the slip 1 identification code from the nonvolatile memory 34 (step S266).

  The print processing unit 323 acquires the slip 2 identification code from the stored print request. The print processing unit 323 reads the slip 2 print data specified by the slip 2 identification code from the volatile memory 33, and causes the print unit 35 to print the slip 2 print data (step S268).

  When the printing unit 35 completes printing of the slip 2 print data, the print processing unit 323 outputs a print completion response of the slip 2 print data to the storage processing unit 322 (step S270). The deletion unit 325 of the storage processing unit 322 deletes the slip 2 print data and the slip 2 identification code from the volatile memory 33 and also deletes the slip 2 identification code from the nonvolatile memory 34 (step S272).

The registration unit 324 of the storage processing unit 322 outputs a print request in which the slip 3 identification code is set to the print processing unit 323 (step S274).
After transmitting the print completion response for the slip 2 print data, the print processing unit 323 causes the print unit 35 to execute the print processing for the slip 3 print data (step S276).
When the printing unit 35 completes printing of the slip 3 print data, the print processing unit 323 outputs a print completion response of the slip 3 print data to the storage processing unit 322 (step S278).
The deletion unit 325 of the storage processing unit 322 deletes the slip 3 print data and the slip 3 identification code from the volatile memory 33 and also deletes the slip 3 identification code from the nonvolatile memory 34 (step S280).

FIG. 7 is a sequence diagram of the order management system when the power of the printer 30 is cut off during slip printing.
In the figure, when the printer 30 is turned on (step S302), the order management system performs the processing of steps S202 to S206 of FIG. 5 (steps S304 to S308). Thereafter, when the controller 20 receives the order data from the handy terminal 10, the order management system performs steps S208 to S222 in FIG. 5 (steps S310 to S324). Further, when the controller 20 receives the order data from the handy terminal 10 after receiving the receipt response for the slip 1 print data, the order management system performs the processing of steps S224 to S236 in FIG. 5 (steps S326 to S338). .

  When the controller 20 receives the order data from the handy terminal 10 after receiving the receipt response for the slip 2 print data, the order management system performs the same processing as steps S252 to S262 in FIG. 6 (steps S340 to S350). 6, when the printing unit 35 of the printer 30 completes the printing of the slip 1 print data, the print processing unit 323 sends a print completion response of the slip 1 print data to the storage processing unit 322, similarly to the processing of steps S264 to S266 in FIG. (Step S352), the deletion unit 325 of the storage processing unit 322 deletes the slip 1 print data and the slip 1 identification code from the volatile memory 33, and deletes the slip 1 identification code from the nonvolatile memory 34 (step S354). . Then, in response to an instruction from the print processing unit 323, when the printing unit 35 starts printing the slip 2 print data (step S356), the printer 30 is turned off (step S358).

  For example, when a problem occurs during printing of the printer 30 and the power cannot be restored unless the power is turned off, the employee turns off the power of the printer 30. Further, for example, the power supply may stop before the printer 30 completes printing due to a power supply trouble or the like. When the power is cut off, the content stored in the volatile memory 33 of the printer 30 disappears, but the content stored in the nonvolatile memory 34 is retained.

  FIG. 8 is a sequence diagram continued from FIG. In the figure, when the printer 30 is turned on again (step S402), the storage processing unit 322 checks whether or not an identification code is stored in the nonvolatile memory 34. A slip resending request is sent to the communication processing unit 321 (step S404).

The communication processing unit 321 receives an unprinted slip retransmission request input from the storage processing unit 322, and determines whether an identification code is stored in the nonvolatile memory 34. When determining that the identification code is stored in the nonvolatile memory 34, the communication processing unit 321 sets the slip 2 identification code “0002” and the slip 3 identification code “0003” stored in the nonvolatile memory 34 together with the connection request. The non-printed slip notification information is output to the transmission / reception unit 31, and the transmission / reception unit 31 is instructed to request retransmission of the non-printed slip (step S406).
The transmission / reception unit 31 transmits the connection request in which unprinted slip notification information is set to the controller 20 (step S408). When receiving the connection request from the printer 30, the second transmission / reception unit 24 of the controller 20 returns a connection response to the printer 30 (step S410).

  The slip reissue processor 223 of the controller 20 reads the slip 2 identification code and the slip 3 identification code from the unprinted slip notification information set in the connection request. The slip reissue processor 223 first reads the order data specified by the slip 2 identification code from the order management data stored in the storage unit 23, and generates slip 2 print data based on the read order data. The slip reissue processing unit 223 instructs the second transmission / reception unit 24 to transmit the generated slip 2 print data and the slip 2 identification code, and the second transmission / reception unit 24 sends the slip 2 print data and the slip 2 identification code to the printer 30. (Step S412).

  When the communication processing unit 321 of the printer 30 receives the slip 2 print data and the slip 2 identification code from the controller 20 via the transmission / reception unit 31 (step S414), the received slip 2 print data, the slip 2 identification code, the storage request, Is output to the storage processing unit 322 (step S416).

  The registration unit 324 of the storage processing unit 322 writes the slip 2 print data and the slip 2 identification code in the volatile memory 33 in association with each other. Since the slip 2 identification code is stored in the nonvolatile memory 34, the registration unit 324 does not write to the nonvolatile memory 34 (step S418). The registration unit 324 notifies the communication processing unit 321 of the end of writing, and the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a response to the controller 20 (step S420). The transmission / reception unit 31 transmits a receipt response of the slip 2 print data to the controller 20 (step S422).

  On the other hand, the registration unit 324 of the printer 30 outputs a print request in which the slip 2 identification code is set to the print processing unit 323 (step S424), and the print processing unit 323 sends the print processing of the slip 2 print data to the print unit 35. This is executed (step S426).

When the second transmission / reception unit 24 of the controller 20 receives the receipt response of the slip 2 print data, the order management system uses the slip 3 identification code instead of the slip 2 identification code, and performs the processing of steps S412 to S424 described above. Execute.
That is, the slip reissuing processing unit 223 of the controller 20 reads the order data specified by the slip 3 identification code from the order management data and generates slip 3 print data, and the second transmitting / receiving unit 24 generates the slip 3 print data and The slip 3 identification code is transmitted to the printer 30. The communication processing unit 321 of the printer 30 receives the slip 3 print data and the identification code from the controller 20 via the transmission / reception unit 31, and outputs them to the storage processing unit 322 together with a save request. The registration unit 324 of the storage processing unit 322 writes the slip 3 print data and the slip 3 identification code in association with each other in the volatile memory 33 and does not write in the nonvolatile memory 34. The transmission / reception unit 31 transmits a receipt response of the slip 3 print data to the controller 20.

FIG. 9 is a diagram illustrating a processing flow of the printer 30 at the time of power activation.
When the power of the printer 30 is turned on (step S502), the communication processing unit 321 determines whether there is unprinted slip print data depending on whether an identification code of unprinted slip print data is stored in the nonvolatile memory 34. Judgment is made (step S504).
If it is determined that the identification code of unprinted slip print data is not stored in the nonvolatile memory 34 (step S504: none), the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a connection request. The transmission / reception unit 31 transmits a connection request to the controller 20 (step S506). The processing in step S506 corresponds to the processing in steps S202 to S204 in FIG. When the transmission / reception unit 31 receives a connection response from the controller 20 (corresponding to step S206 in FIG. 6), it waits for reception of print data (step S508).

  On the other hand, if it is determined in step S504 that an identification code of unprinted slip print data is stored (step S504: present), the communication processing unit 321 receives the identification code read from the nonvolatile memory 34 together with the connection request. The set unprinted slip notification information is output to the transmission / reception unit 31 to instruct to request retransmission of the unprinted slip.

  The transmission / reception unit 31 transmits a connection request in which unprinted slip notification information is set to the controller 20 (step S510). The processing in step S510 corresponds to the processing in steps S404 to S408 in FIG. When the transmission / reception unit 31 receives a connection response from the controller 20 (corresponding to step S410 in FIG. 8), it waits for reception of print data (step S508).

  FIG. 10 is a diagram showing an order processing flow of the controller 20. The order processing is processing for receiving order data from the handy terminal 10 and causing the printer 30 to print slip print data generated based on the received order data.

  The print request receiving unit 220 of the controller 20 determines whether the first transmitting / receiving unit 21 has received the order data from the handy terminal 10 (step S602). When the print request receiving unit 220 determines that the order data has not been received (step S602: NO), the controller 20 performs the process of step S610.

  On the other hand, when the print request receiving unit 220 determines that the order data has been received (step S602: YES), the received order data is output to the order processing unit 221 (step S604). The order processing unit 221 additionally registers the received order data and the order time in association with the order management data stored in the storage unit 23 (step S606). When the slip processing unit 222 assigns a slip number, it generates slip print data from the order data and assigns an identification code. The slip processing unit 222 writes the slip number and the identification code assigned in association with the order data in the order management data stored in the storage unit 23, and stores the generated slip print data and the identification code in association with each other. The data is written in the unit 23 (step S608). After the writing, the controller 20 executes the process of step S610.

When the second transmission / reception unit 24 receives a connection request from the printer 30 (step S610: YES), the second transmission / reception unit 24 establishes a connection with the printer 30 and outputs the received connection request to the print request reception unit 220 (step S612).
When determining that the connection request includes unprinted slip notification information (step S614: YES), the print request receiving unit 220 outputs the unprinted slip notification information to the slip reissue processing unit 223. When the slip reissue processing unit 223 acquires the identification code from the unprinted slip notification information and reads the order data from the order management data stored in the storage unit 23 corresponding to the acquired identification code, the read order data Based on the above, slip print data is generated. Hereinafter, the slip print data generated from the order data corresponding to the identification code set in the unprinted slip notification information is referred to as “unprinted slip data”. The slip reissue processing unit 223 writes the generated unprinted slip data and its identification code in the storage unit 23 (step S616), and the controller 20 performs the processing from step S602.

  If the second transmission / reception unit 24 has not received a connection request for the printer 30 in step S610 (step S610: NO), or in step S614, the print request reception unit 220 includes unprinted slip notification information in the connection request. If it is determined that it is not included (step S614: NO), the slip reissue processor 223 determines whether the unprinted slip data that has not yet been transmitted to the printer 30 is stored in the storage unit 23. It is determined whether there is print slip data (step S618).

If unprinted slip data is stored in the storage unit 23 (step S618: YES), the slip reissue processing unit 223 determines that there is untransmitted unprinted slip data, and determines that there is unprinted slip data from the storage unit 23. And its identification code. The slip reissue processing unit 223 outputs the read unprinted slip data and its identification code to the second transmitting / receiving unit 24 and instructs transmission to the printer 30.
When a plurality of unprinted slip data is stored, the slip reissue processor 223 reads the order time corresponding to the identification code of the unprinted slip data from the order management data, and the identification code with the earliest read order time Then, unprinted slip data corresponding to the identification code is output to the second transmitting / receiving unit 24 to instruct transmission to the printer 30. The second transmission / reception unit 24 transmits the unprinted slip data and the identification code input from the slip reissue processing unit 223 to the printer 30 (step S620).

  When the second transmission / reception unit 24 receives a reception response from the printer 30 within a predetermined time corresponding to the unprinted slip data transmitted in step S620 (step S622: YES), the slip reissue processing unit 223 The unprinted slip data and the identification code transmitted in S620 are deleted from the storage unit 23 (Step S624), and the controller 20 executes the processing from Step S602. On the other hand, when the second transmission / reception unit 24 does not receive the reception response from the printer 30 within the predetermined time (step S622: NO), the controller 20 does not delete the unprinted slip data and performs the processing from step S602. Run.

In step S618, when the slip reissue processing unit 223 determines that the unprinted slip data is not stored in the storage unit 23 and there is no unprinted unprinted slip data (step S618: NO), the slip processing unit 222 determines whether there is slip print data that has not been transmitted, depending on whether slip print data that has not yet been transmitted to the printer 30 is stored in the storage unit 23 (step S626). When the slip print data whose transmission has not been completed is not stored in the storage unit 23 (step S626: NO), the controller 20 executes the processing from step S602. If the slip print data is stored in the storage unit 23 (step S626: YES), the slip processing unit 222 stores the slip print data that has been written in step S608 and has not yet been transmitted, and its identification code. Read from the unit 23. The slip processing unit 222 outputs the read slip print data and its identification code to the second transmitting / receiving unit 24 and instructs transmission to the printer 30.
When a plurality of slip print data is stored, the slip processing unit 222 reads the order time corresponding to the identification code of the slip print data from the order management data stored in the storage unit 23, and the read order time is The earliest identification code and slip print data corresponding to the identification code are output to the second transmission / reception unit 24 to instruct transmission to the printer 30. The second transmitting / receiving unit 24 transmits the slip print data and the identification code input from the slip processing unit 222 to the printer 30 (step S628).

  When the second transmission / reception unit 24 receives a reception response from the printer 30 within a predetermined time corresponding to the slip print data transmitted in step S628 (step S630: YES), the slip processing unit 222 transmits in step S628. The slip print data and its identification code are deleted from the storage unit 23 (step S632), and the controller 20 executes the processing from step S602. On the other hand, when the second transmission / reception unit 24 does not receive the reception response from the printer 30 within the predetermined time (step S630: NO), the controller 20 executes the processing from step S602 without deleting the slip print data. To do.

Through the above processing, the controller 20 receives the order data from the handy terminal 10 and the connection request from the printer 30 as needed.
When the order data is received while the printer 30 is powered off, the controller 20 generates slip print data from the received order data, and transmits the generated slip print data and the identification code to the printer 30.
However, since the reception response is not received from the printer 30 corresponding to the transmitted slip print data and the identification code, the controller 20 retransmits the slip print data. When order data is further received during the resending of the slip print data, the controller 20 generates slip print data from the received order data and stores it. When the printer 30 is turned on again, the controller 20 receives a connection request from the printer 30, and unprinted slip notification information is set in the received connection request, the slip that was resent while the printer 30 was turned off The unprinted slip data requested by the unprinted slip notification information is preferentially transmitted to the printer 30 over the print data and the slip print data stored without transmission.

  Note that the slip print data generated by the slip processing unit 222 in step S608 includes the person-in-charge code, table number, and detail data set in the order data, the slip number that is the identification code of the slip print data, and the identification code. Correspondingly, it is print data for printing information including the order time read from the order management data in the storage unit 23 in a predetermined layout. When other information such as handwritten character information is included in the order data, the order data may be print data for further printing.

  The unprinted slip data generated by the slip reissue processing unit 223 in step S616 may be the same as the slip print data generated by the slip processing unit 222 in step S608. The data may be slip print data for further printing information indicating that the data is a resent slip. The information indicating the resending slip can be, for example, a predetermined character or symbol, a word or document indicating a warning, an elapsed time from the order time of the order data to the current time, or the like. By adding and printing such information, it becomes easier for the person in charge of cooking to notice the existence of an unprinted voucher, and it is possible to easily grasp how quickly work related to the voucher should be handled. it can.

  The slip processing unit 222 of the controller 20 does not delete the slip print data that has been successfully transmitted from the storage unit 23, and the slip reissue processing unit 223 corresponds to the identification code set in the unprinted slip notification information. The slip print data may be read from the storage unit 23 and transmitted to the printer 30.

  In addition, the storage processing unit 322 of the printer 30 adds print data for printing information indicating that printing is performed by the retransmitted slip print data to the slip print data (unprinted slip data) retransmitted from the controller 20. May be.

According to the present embodiment, when receiving the slip print data from the controller 20, the printer 30 stores the identification code added to the received slip print data in the nonvolatile memory 34, and the print unit 35 stores the slip print data. When printing is completed, the identification code of the slip print data is deleted from the nonvolatile memory 34.
Even when a power interruption occurs between the time when the slip print data and the identification code are written to the nonvolatile memory 34 and the time when the print portion 35 prints the slip print data, the stored contents in the nonvolatile memory 34 are preserved. It becomes. When the printer 30 is turned on again, if the identification code remains stored in the nonvolatile memory 34, the printer 30 has finished printing the slip print data specified by the identification code. If not, the identification code read from the nonvolatile memory 34 is added to the connection request and transmitted to the controller 20.
The controller 20 specifies the order data based on the identification code added to the connection request received from the printer 30, and generates slip print data from the specified order data. At this time, the controller 20 determines the order data specified by the identification code notified by the connection request rather than the slip print data generated from the order data received from the handy terminal 10 when the printer 30 is powered off. Priority is given to the slip print data generated from, and the data is transmitted to the printer 30 in order of the order time. Thus, the slip print data generated from the order data can be printed on the printer 30 in the order in which the controller 20 receives the order data.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the first embodiment, the slip that the controller 20 prints on the printer 30 may be a multi-detail slip including a plurality of details included in one slip, or a one-line specification including a strip slip that is partially cut for each specification. It may be a slip. In the present embodiment, the controller causes the printer to print a one-line detailed slip, and the printer manages whether printing is completed in units of strip slips. Hereinafter, the difference from the first embodiment will be mainly described.

  The order management system of this embodiment includes a printer 30a shown in FIG. 11 instead of the printer 30 of the first embodiment. The controller 20 is the same as that of the first embodiment, but the slip processing unit 222 and the slip reissue processing unit 223 generate slip print data of a one-line detailed slip. The slip print data of one line detail slip includes strip print data for printing a strip slip corresponding to each detail data included in the order data, and a cut command set between the strip print data. Each strip print data corresponds to the order item and quantity indicated by the corresponding detail data, the person-in-charge code and table number set in the order data, the slip number which is the identification code of the slip print data, and the identification code. Print data for printing information including the order time read from the order management data in the storage unit 23 in a predetermined layout.

  FIG. 11 is a block diagram showing the internal configuration of the printer 30a of this embodiment. In this figure, the same parts as those of the printer 30 according to the first embodiment shown in FIG. The printer 30a shown in the figure is different from the printer 30 of the first embodiment shown in FIG. 3 in that a processing unit 32a is provided instead of the processing unit 32, and a volatile memory 33a is provided instead of the volatile memory 33. In this case, a nonvolatile memory 34 a is provided instead of the nonvolatile memory 34.

The volatile memory 33a stores the print data received from the controller 20, the identification code of the print data, and the number of strip print data that has been printed out of the strip print data included in the slip print data of the identification code. The non-volatile memory 34a is a RAM with a backup battery, a flash ROM that can be written to and erased, and the identification code of slip print data that has not been printed, and the strip print data included in the slip print data of the identification code. The number of strip print data that has been printed is stored.
The number of printed strip print data is indicated by the number of times the cut command set in the slip print data is executed during the printing of the slip print data (the number of cuts).

The difference between the processing unit 32a and the processing unit 32 of the printer 30a of the first embodiment is that a storage processing unit 322a is provided instead of the storage processing unit 322, and a print processing unit 323a is provided instead of the print processing unit 323. Is a point.
The storage processing unit 322a includes a registration unit 324a, a deletion unit 325a, an update unit 326, and a print information addition unit 327. The registering unit 324a associates the print data received from the controller 20 and its identification code with the initial value of the number of cuts, and writes it in the volatile memory 33a. Also, the registration unit 324a writes the received identification code and the initial value of the number of cuts in the nonvolatile memory 34a. The update unit 326 receives a notification of completion of printing of the strip slip from the print processing unit 323a, and updates the number of cuts. The deletion unit 325a deletes the slip print data that has been printed, its identification code, and the number of cuts from the volatile memory 33a, and also deletes the identification code and the number of cuts of the slip print data that has been printed from the nonvolatile memory 34a. Based on the number of cuts read from the non-volatile memory 34a corresponding to the identification code of the slip print data retransmitted from the controller 2, the print information adding unit 327 determines how far the strip print data in the slip print data has been printed. to decide. The print information adding unit 327 adds print data for printing information indicating whether or not printing has been performed to each strip print data included in the slip print data.
The print processing unit 323a instructs the printing unit 35 to print the print data read from the volatile memory 33a. The print processing unit 323a instructs the cutter unit 36 to cut the roll paper according to the cut command included in the print data, completes printing of the strip print data (execution of the cut command), and prints the slip print data. The storage processing unit 322a is notified of the completion of printing.

FIG. 12 is a sequence diagram of the order management system when the printing of the slip is normally completed after the printer 30a is turned on.
In the figure, when the printer 30a is powered on (step S701), the communication processing unit 321 determines whether an identification code is stored in the nonvolatile memory 34a. Since the identification code is not stored in the nonvolatile memory 34a, the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a connection request (step S702). The transmission / reception unit 31 transmits a connection request to the controller 20 (step S704). When the second transmission / reception unit 24 of the controller 20 receives the connection request and recognizes the activation of the printer 30a, it returns a connection response to the printer 30a (step S706).

  When receiving the order data from the handy terminal 10, the controller 20 generates the slip 3 print data that is the slip print data of the slip 3 as in the first embodiment, and the slip 3 print data and the slip 3 identification code “0003”. Is transmitted to the printer 30a (step S708). The generated slip 3 print data is print data of a one-line detailed slip including three strip print data.

When the communication processing unit 321 of the printer 30a receives the slip 3 print data and the slip 3 identification code from the controller 20 via the transmission / reception unit 31 (step S710), the received slip 3 print data, the slip 3 identification code, the storage request, Is output to the storage processing unit 322a (step S712). The registration unit 324a of the storage processing unit 322a correlates and writes the slip 3 print data, the slip 3 identification code, and the cut count “0” to the volatile memory 33a, and associates the slip 3 identification code with the cut count “0”. In addition, the data is written in the nonvolatile memory 34a (step S714). The registration unit 324a notifies the communication processing unit 321 of the end of writing, and the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a response to the controller 20 (step S716).
The transmission / reception unit 31 transmits a receipt response of the slip 3 print data to the controller 20 (step S718).

  On the other hand, the registration unit 324a of the printer 30a outputs a print request in which the slip 3 identification code is set to the print processing unit 323a (step S720). The print processing unit 323a reads the slip 3 print data specified by the slip 3 identification code set in the print request from the volatile memory 33a, and performs the print processing of the first strip print data included in the slip 3 print data. 35 (step S722).

  When the printing unit 35 completes printing of the first strip print data included in the slip print data, the print processing unit 323a performs a partial cut of the roll paper in accordance with the cut command described in the slip print data after the strip print data. While making it execute by the cutter part 36, a strip completion response is output to the memory | storage process part 322a (step S724).

  The update unit 326 of the storage processing unit 322a sets the number of cuts stored in the volatile memory 33a and the nonvolatile memory 34a corresponding to the slip 3 identification code to a value “1” obtained by adding 1 to the current value “0”. Update (step S726). After the output of the strip completion response, the print processing unit 323a causes the printing unit 35 to execute print processing of the second strip print data included in the slip 3 print data (step S728).

  FIG. 13 is a sequence diagram continued from FIG. When the printing unit 35 of the printer 30 completes the printing of the second strip print data in step S728 of FIG. 12, the print processing unit 323a follows the cut command described in the slip print data after the strip print data. Is executed by the cutter unit 36, and a strip completion response is output to the storage processing unit 322a (step S752).

  The update unit 326 of the storage processing unit 322a sets the number of cuts stored in the volatile memory 33a and the non-volatile memory 34a corresponding to the slip 3 identification code to a value “2” obtained by adding 1 to the current value “1”. Update (step S754). After the output of the strip completion response, the print processing unit 323a causes the printing unit 35 to execute print processing of the third strip print data included in the slip 3 print data (step S756).

  After receiving the receipt response of the slip 3 print data transmitted by the printer 30a in step S718 of FIG. 12, the controller 20 further receives order data from the handy terminal 10 and prints the slip 4 which is the slip print data of the slip 4. The data and the slip 4 identification code “0004” are transmitted to the printer 30a (step S758).

  The printer 30a performs the processing of steps S710 to S720 shown in FIG. 12 for the received slip 4 print data and slip 4 identification code (steps S760 to S770). That is, the transmission / reception unit 31 of the printer 30a outputs the received slip 4 print data and the slip 4 identification code together with the save request to the storage processing unit 322a. The registration unit 324a of the storage processing unit 322a correlates and writes the slip 4 print data, the slip 4 identification code, and the cut count “0” to the volatile memory 33a, and associates the slip 4 identification code with the cut count “0”. In addition, the transmission / reception unit 31 transmits a receipt response of the slip 4 print data to the controller 20. The registration unit 324a outputs a print request in which the slip 4 identification code is set to the print processing unit 323a.

When the printing unit 35 completes the printing of the third strip print data included in the slip 3 print data, the print processing unit 323a determines that the printing of all the strip print data included in the slip 3 print data has been completed. The print completion response of the slip 3 print data is output to the storage processing unit 322a (step S772).
The deletion unit 325a of the storage processing unit 322a deletes the slip 3 print data, its identification code, and the number of cuts from the volatile memory 33a, and deletes the pair of the slip 3 identification code and the number of cuts from the nonvolatile memory 34a (step S774). .
When the print processing unit 323a reads out the slip print data corresponding to the slip 4 identification code set in the stored print request from the volatile memory 33a, the print processing unit 323a prints the first strip print data of the slip 4 print data. 35 (step S776).

  FIG. 14 is a diagram illustrating an output example of a cooking slip that is a one-line detailed slip when the printer 30a has completed printing normally. This figure is a cooking slip printed based on slip print data including three strip print data, and consists of strip slips r1, r2, and r3. The strip slip r1 and the strip slip r2 and the strip slip r2 and the strip slip r3 are partially cut by executing a cut command described between the strip print data. A slip number, a table number, an order time, and a person-in-charge code are printed on each strip slip r1, r2, r3. In addition, each of the strip slips r1, r2, and r3 is printed with the ordered product and the ordered quantity indicated by the corresponding detailed data.

FIG. 15 is a sequence diagram of the order management system when the printer 30a is powered off during slip printing. This figure shows a case where the printer 30a is powered off after step S764 in FIG. 13 and before step S772. That is, while the cutter unit 36 of the printer 30a completes the partial cut of the second strip slip of the slip 3 print data, and the printing unit 35 is printing the third strip print data of the slip 3 print data, the storage processing unit 322a When the update unit 326 writes the slip 4 identification code, the print data, and the initial value of the number of cuts in the volatile memory 33a, and the initial value of the slip 4 identification code and the number of cuts in the nonvolatile memory 34a, the printer 30a is turned off. This is the case.
For example, when the printing of the second strip slip of slip 3 is completed and a paper jam occurs during the printing of the last strip slip, the employee turns off the printer 30a and turns it on again. It is. In this case, the printer 30a transmits a request for reissuance of the slip 3 print data to the controller 20 in response to a connection request after turning on the power, re-acquires the slip 3 print data from the controller 20, and then restarts from the first strip print data. Perform printing.

In the figure, when the power of the printer 30a is turned on again (step S802), the storage processing unit 322a checks whether or not an identification code is stored in the nonvolatile memory 34a. A slip retransmission request is sent to the communication processing unit 321 (step S804).
The communication processing unit 321 receives an input of an unprinted slip resending request from the storage processing unit 322a, and determines whether an identification code is stored in the nonvolatile memory 34a. When the communication processing unit 321 determines that the identification code is stored in the nonvolatile memory 34a, the communication processing unit 321 sends the slip 3 identification code “0003” and the slip 4 identification code “0004” stored in the nonvolatile memory 34a together with the connection request. The set unprinted slip notification information is output to the transmission / reception unit 31, and the transmission / reception unit 31 is instructed to request retransmission of the unprinted slip (step S806).
The transmission / reception unit 31 transmits the connection request in which unprinted slip notification information is set to the controller 20 (step S808). When receiving the connection request from the printer 30a, the second transmission / reception unit 24 of the controller 20 returns a connection response to the printer 30a (step S810).

  The slip reissue processor 223 of the controller 20 reads the slip 3 identification code and the slip 4 identification code from the unprinted slip notification information set in the connection request. The slip reissue processor 223 first reads the order data specified by the slip 3 identification code from the order management data stored in the storage unit 23, and generates slip 3 print data based on the read order data. The generated slip 3 print data is the same as the slip 3 print data transmitted by the controller 20 in step S708 of FIG. The slip reissue processor 223 instructs the second transmitter / receiver 24 to transmit the generated slip 3 print data and slip 3 identification code, and the second transmitter / receiver 24 sends the slip 3 print data and slip 3 identification code to the printer 30a. (Step S812).

When the communication processing unit 321 of the printer 30a receives the slip 3 print data and the slip 3 identification code from the controller 20 via the transmission / reception unit 31 (step S814), the received slip 3 print data, the slip 3 identification code, the storage request, Is output to the storage processing unit 322a (step S816).
The registration unit 324a of the storage processing unit 322a writes the slip 3 print data, the slip 3 identification code, and the number of cuts set with the initial value “0” in the volatile memory 33a in association with each other. The registration unit 324a reads the number of cuts “2” corresponding to the slip 3 identification code from the nonvolatile memory 34a, and outputs it to the print information adding unit 327.
The print information adding unit 327 determines that the printing of the third and subsequent strip print data is not completed because the number of cuts read by the registration unit 324a is “2”. Since the slip 3 print data includes three strip print data, the print information adding unit 327 includes the first and second strip print data in the slip 3 print data stored in the volatile memory 33a. Print data for printing information indicating that printing has been completed is added, and print data for printing information indicating that printing has not been performed is added to the third strip print data (step S818).

  The printer 30a performs a printing process for the slip 3 print data shown in step S716 and subsequent steps in FIG. That is, the registration unit 324a notifies the communication processing unit 321 of the end of writing, and the communication processing unit 321 instructs the transmission / reception unit 31 to transmit a response to the controller 20 (step S822). The transmission / reception unit 31 transmits a receipt response of the slip 3 print data to the controller 20 (step S824). The registration unit 324a outputs a print request in which the slip 3 identification code is set to the print processing unit 323a (step S826), and the print processing unit 323a prints the print processing of the first strip print data included in the slip 3 print data. The process is executed by the unit 35 (step S828).

  Further, when the second transmission / reception unit 24 of the controller 20 receives the reception response of the slip 3 print data transmitted in step S824, the slip reissue processing unit 223 reads the slip based on the order data specified by the slip 4 identification code. 4 print data is generated, and the second transmitter / receiver 24 transmits the slip 4 print data and the slip 4 identification code to the printer 30a.

FIG. 16 is a diagram showing a print example of the cooking slip based on the slip print data retransmitted after the power is turned on again. In the figure, the print direction arrow points from the bottom to the top, which means that the printed strip slip moves in the direction of the arrow as printing proceeds. That is, the strip slip at the top is the first strip slip printed. In the figure, when printing is completed normally, the printer 30a is turned off while the third strip slip r3 is being printed by the slip 3 print data on which the same cooking slip as in FIG. 14 is printed. This is an example of printing when the slip 3 print data is retransmitted from the controller 20 because it has occurred.
Since the print information adding section 327 of the printer 30a adds information indicating whether or not printing has been completed to each strip print data of the resent slip 3 print data, the printed cooking slip is the strip shown in FIG. It consists of slips r1 ′, r2 ′, r3 ′. In the strip slip r1 ′, “completed” is further printed as information indicating that the strip has been printed on the printed content of the strip slip r1. Similarly, the strip slip r2 ′ is further printed with “completed” in addition to the printed content of the strip slip r2. On the other hand, in addition to the print contents of the strip slip r3, “non-printed” is further printed on the strip slip r3 ′ as information indicating that the strip slip r3 ′ has been printed for the first time.

The processing at the time of power activation of the printer 30a of the present embodiment is the same as the processing at the time of power activation of the first embodiment shown in FIG.
Further, the order processing of the controller 20 of the present embodiment is the same as the order processing flow of the first embodiment shown in FIG. However, in step S608, the slip processing unit 222 generates slip print data for one line detail slip, and in step S616, the slip reissue processing unit 223 generates unprinted slip data for one line detail slip.

  According to the present embodiment, when printing a one-line detailed slip based on the resent slip print data, the printer 30a prints information indicating whether or not each strip slip has been printed. By printing the information indicating reprinting on the strip slip, it is possible to effectively prevent the order from being cooked twice, and the information indicating that it is not printed is strip slip. By printing on, it is possible to call attention that time has passed since the order was placed.

[Third Embodiment]
Next, a third embodiment of the present invention will be described. In the order management system of this embodiment, when the power is cut off while the printer is printing a one-line detailed slip, the controller generates slip print data for printing only a strip slip that has not been printed. Hereinafter, the difference from the second embodiment will be mainly described.
The order management system of this embodiment includes a controller 20b shown in FIG. 17 instead of the controller 20 of the second embodiment, and a printer 30b shown in FIG. 18 instead of the printer 30a of the second embodiment. Hereinafter, the difference from the second embodiment will be mainly described.

FIG. 17 is a block diagram showing the internal configuration of the controller 20b of this embodiment. In this figure, the same parts as those of the controller 20 according to the first embodiment shown in FIG.
The controller 20b shown in the figure is different from the controller 20 of the first embodiment shown in FIG. 2 in that a processing unit 22b is provided instead of the processing unit 22. The processing unit 22b is different from the processing unit 22 of the controller 20 of the first embodiment in that a slip reissuing processing unit 223b is provided instead of the slip reissuing processing unit 223. When the identification code and the number of cuts are set in the connection request received by the second transmission / reception unit 24 from the printer 30, the slip reissue processing unit 223b searches the order management data stored in the storage unit 23 and The order data corresponding to the identification code is specified. The slip reissue processing unit 223b generates slip print data of one line detail slip from the specified order data in consideration of the received number of cuts and excluding the printed strip print data.

FIG. 18 is a block diagram showing the internal configuration of the printer 30b of this embodiment. In this figure, the same parts as those of the printer 30a according to the second embodiment shown in FIG.
The printer 30b shown in the figure is different from the printer 30a of the second embodiment shown in FIG. 11 in that a processing unit 32b is provided instead of the processing unit 32a. The processing unit 32b is different from the processing unit 32a of the printer 30a of the second embodiment in that a communication processing unit 321b (unprinted slip notification unit) is provided instead of the communication processing unit 321, and instead of the storage processing unit 322a. The memory processing unit 322b is provided.

When the power is turned on, the communication processing unit 321b reads the set of the identification code and the number of cuts stored in the nonvolatile memory 34a and sets it as a connection request.
The storage processing unit 322b is different from the storage processing unit 322a of the second embodiment in that a registration unit 324b is provided instead of the registration unit 324a, and a print information addition unit 327 is not provided. The registration unit 324b writes the print data received from the controller 20b, its identification code, and the initial value of the number of cuts in association with each other in the volatile memory 33a, and when the received identification code is not stored in the nonvolatile memory 34a, The initial value of the identification code and the number of cuts is written in the nonvolatile memory 34a.

  In the order management system of this embodiment, the operation of the order management system when the slip print data is normally printed after the printer 30b is turned on is the same as that of the second embodiment shown in FIGS. is there.

FIG. 19 is a sequence diagram of the order management system when the printer 30b is turned off during slip printing. This figure shows a case where the printer 30b is powered off after step S764 in FIG. 13 and before step S772.
In the figure, when the printer 30b is turned on again (step S902), the storage processing unit 322b checks whether or not an identification code is stored in the nonvolatile memory 34a. A slip resending request is sent to the communication processing unit 321b (step S904).

The communication processing unit 321b receives an unprinted slip resending request input from the storage processing unit 322b, and determines whether an identification code is stored in the nonvolatile memory 34a. When the communication processing unit 321b determines that the identification code is stored in the nonvolatile memory 34a, the communication processing unit 321b includes a combination of the slip 3 identification code “0003” and the number of cuts “2” stored in the nonvolatile memory 34a together with the connection request. The unprinted slip notification information in which the set of the slip 4 identification code “0004” and the number of cuts “0” is set is output to the transmission / reception unit 31 and the transmission / reception unit 31 is instructed to request retransmission of the unprinted slip (step S906). ).
The transmission / reception unit 31 transmits the connection request in which unprinted slip notification information is set (step S906) and transmits it to the controller 20b (step S908). When receiving the connection request from the printer 30b, the second transmission / reception unit 24 of the controller 20b returns a connection response to the printer 30b (step S910).

The slip reissue processor 223b of the controller 20b reads the slip 3 identification code and the slip 4 identification code from the unprinted slip notification information set in the connection request. The slip reissue processor 223b first reads the order data specified by the slip 3 identification code from the order management data stored in the storage 23, and the printing is completed based on the read order data and the number of cuts. The re-sending slip 3 print data for printing the one-line detail slip including only the short strip slip is generated. That is, since the number of cuts corresponding to the slip 3 identification code is “2”, the slip reissue processing unit 223b generates retransmission slip 3 print data including the third and subsequent strip print data.
The slip reissue processing unit 223b instructs the second transmission / reception unit 24 to transmit the generated retransmission slip 3 print data and the slip 3 identification code, and the second transmission / reception unit 24 sends the retransmission slip 3 print data and the slip 3 identification code. The data is transmitted to the printer 30b (step S912).

When the communication processing unit 321b of the printer 30b receives the retransmission slip 3 print data and the slip 3 identification code from the controller 20b via the transmission / reception unit 31 (step S914), the received retransmission slip 3 print data and the slip 3 identification code are stored. The request is output to the storage processing unit 322b (step S916). The registration unit 324b of the storage processing unit 322b associates the re-sending slip 3 print data and the slip 3 identification code, and writes them in the volatile memory 33a (step S918). The registration unit 324b does not write to the nonvolatile memory 34a because the slip 3 identification code is already stored.
The registration unit 324b notifies the communication processing unit 321b of the end of writing, and the communication processing unit 321b instructs the transmission / reception unit 31 to transmit a response to the controller 20b (step S922). The transmission / reception unit 31 transmits a receipt response of the slip 3 print data to the controller 20b (step S924).

The registration unit 324b of the printer 30b outputs a print request in which the slip 3 identification code is set to the print processing unit 323a (step S926). The print processing unit 323a reads the reprint slip 3 print data specified by the slip 3 identification code set in the print request from the volatile memory 33a, and reads the strip print data (the slip 3 print data of the reprint slip 3 print data). The printing section 35 is caused to execute a printing process (corresponding to the third strip printing data) (step S928).
When the printing unit 35 completes the printing of the strip print data included in the retransmission slip 3 print data, the print processing unit 323a determines that the printing of all the strip print data included in the retransmission slip 3 print data has been completed. Then, the response to the completion of printing of the resending slip 3 print data is output to the storage processing unit 322b (step S930). Thus, the deletion unit 325a of the storage processing unit 322b deletes the set of the reprint slip 3 print data, the slip 3 identification code, and the number of cuts from the volatile memory 33a, and also deletes the set of the slip 3 identification code and the number of cuts in the nonvolatile memory. It deletes from 34a (step S932).

  Further, when the second transmission / reception unit 24 of the controller 20b receives the reception response of the slip 3 print data transmitted in step S924, the slip reissue processing unit 223b resends based on the order data specified by the slip 4 identification code. Form 4 print data is generated. Since the number of cuts corresponding to the slip 4 identification code is “0”, the slip reissue processor 223b includes all the strip print data, that is, the same as the slip 4 print data transmitted in step S758 of FIG. Resend slip 4 print data is generated. The second transmission / reception unit 24 transmits the resending slip 4 print data and the slip 4 identification code to the printer 30b.

  FIG. 20 is a diagram showing a print example of a cooking slip based on the slip print data retransmitted after the power is turned on again. In the figure, when the printing is normally completed, the printer 30b is turned off while the third strip slip r3 is being printed by the slip 3 print data in which the same print cooking slip as that in FIG. 14 is printed. It is an example of printing of the resending slip 3 print data transmitted from the controller 20b because it occurred. As shown in the figure, the printed cooking slip consists only of the strip slip r3 shown in FIG.

  According to the present embodiment, it is possible to print only the strip slip that has not been printed out of the one-line detailed slip, so that it is possible to prevent the order from being cooked twice. Moreover, since unnecessary printing is not performed, printing paper can be saved.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described. In the present embodiment, the controller causes the printer to print a slip that includes information about the time when printing was delayed due to power failure. Hereinafter, the difference from the first embodiment will be mainly described.

The order management system of this embodiment includes a controller 20c shown in FIG. 21 instead of the controller 20 of the first embodiment.
FIG. 21 is a block diagram showing the internal configuration of the controller 20c of this embodiment. In this figure, the same parts as those of the controller 20 according to the first embodiment shown in FIG.
The controller 20c shown in the figure is different from the controller 20 of the first embodiment shown in FIG. 2 in that a processing unit 22c is provided instead of the processing unit 22. The processing unit 22c is different from the processing unit 22 of the controller 20 of the first embodiment in that a slip reissuing processing unit 223c is provided instead of the slip reissuing processing unit 223. The slip reissue processing unit 223c generates slip print data for printing a slip including information on the time when printing is delayed as information indicating retransmission of the slip print data.

  The sequence of the order management system of the present embodiment is the same as that of the first embodiment shown in FIGS.

FIG. 22 is a diagram showing an order processing flow of the controller 20c. The order processing flow shown in the figure executes step S615 and step S617 instead of the processing in step S616 of the order processing flow of the first embodiment shown in FIG.
In step S615, the slip reissue processor 223c of the controller 20c reads the order data and the order time from the order management data stored in the storage 23 corresponding to the identification code set in the unprinted slip notification information. And the elapsed time from the read order time to the current time is calculated. In step S617, the slip reissue processor 223c adds information indicating the elapsed time to the slip print data similar to the slip print data generated by the slip processor 222 based on the read order data. Unprinted slip data is generated (step S617).

  FIG. 23 is a diagram illustrating a print example of a cooking slip based on unprinted slip data. The figure shows an example of printing when the slip reissue processing unit 223c of the controller 20c generates unprinted slip data by adding print data for printing information indicating the elapsed time before the slip print data. Show. Since the elapsed time is printed on the header added in front of the slip, such as “** 12 minutes have elapsed since the order **”, it is possible to call attention to the person in charge of cooking. In addition, by knowing the elapsed time, the person in charge of cooking, etc. can specifically act on how quickly the work relating to the slip should be handled.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described. The order management system according to the present embodiment includes a plurality of printers. When a power failure occurs in a printer, the controller receives a request for reissuing slip print data from another printer. The controller resends the slip print data requested to be reissued to another printer that has transmitted the reissue request, and prints it. When the power of the printer that has been turned off is turned on again, as in the first embodiment, an identification code of unprinted slip print data stored in the nonvolatile memory is transmitted to the controller together with the connection request. Since the controller has already resent the slip print data of the notified identification code to another printer, the controller returns a request to delete the unprinted slip print data. When the printer whose power is turned on again receives a request to delete unprinted slip print data, it deletes the print data identification code stored in the nonvolatile memory. Hereinafter, the difference from the first embodiment will be mainly described.

  FIG. 24 is a diagram showing an overall configuration of the order management system according to the present embodiment. As shown in the figure, the order management system includes a controller 20d instead of the controller 20 of the first embodiment shown in FIG. 1, and includes a printer 30d and a printer 30e instead of the printer 30. In the figure, only one printer 30d and one printer 30e are shown, but a plurality of printers may be provided. The printer 30d prints cooking slip print data which is slip print data of the cooking slip, and the printer 30e prints guest slip print data which is the slip print data of the guest slip. The guest slip is a slip that the customer brings to the cashier at the time of accounting, and the staff in charge of customer service gives the guest slip to the customer after providing all the ordered items. In this way, the type of slip to be printed by each printer 30d, 30e is determined in advance.

  FIG. 25 is a block diagram showing the internal configuration of the controller 20d of this embodiment, and only functional blocks related to this embodiment are extracted and shown. In this figure, the same parts as those of the controller 20 according to the first embodiment shown in FIG. The controller 20d shown in FIG. 2 differs from the controller 20 of the first embodiment shown in FIG. 2 in that a processing unit 22d is provided instead of the processing unit 22, and a storage unit 23d is provided instead of the storage unit 23. It is.

  The storage unit 23d stores order management data, print data that has not been transmitted, and an identification code of the reissued slip print data. The order management data of the present embodiment is data in which order data, order time, slip number, and identification code for identifying each slip print data generated from the order data are associated with each other.

  The processing unit 22d differs from the processing unit 22 of the first embodiment shown in FIG. 2 in that a slip processing unit 222d is provided instead of the slip processing unit 222, and a slip reissue is performed instead of the slip reissue processing unit 223. It is a point provided with the process part 223d.

The slip processing unit 222d assigns a slip number to the received order data. The slip processing unit 222d generates each slip print data such as cooking slip print data and guest slip print data from the order data.

The slip processing unit 222d writes the slip number and identification code assigned in association with the order data in the order management data stored in the storage unit 23d.
Further, the slip processing unit 222d writes the generated cooking slip print data and the identification code of the cooking slip print data in association with each other in the storage unit 23d, and generates the generated guest slip print data and the guest slip print data. The identification code is associated and written in the storage unit 23d (step S1408). After the writing, the controller 20d executes the process of step S1410.

  When the second transmission / reception unit 24 receives a connection request from the printer 30d or the printer 30e (step S1410: YES), the second transmission / reception unit 24 establishes a connection with the printer 30d or the printer 30e that is the transmission source of the connection request, and receives the received connection request. The data is output to the print request receiving unit 220 (step S1412).

  When determining that the connection request includes unprinted slip notification information (step S1414: YES), the print request receiving unit 220 outputs the unprinted slip notification information to the slip reissue processing unit 223d. The slip reissue processor 223d acquires the identification code from the unprinted slip notification information, and reads the transmission destination specifying information included in the acquired identification code. The slip reissue processing unit 223d determines the type of slip corresponding to the transmission destination indicated by the read transmission destination specifying information. When the slip reissue processing unit 223d reads the order data from the order management data stored in the storage unit 23d corresponding to the acquired identification code, the slip reissue processing unit 223d displays the slip print data of the determined type based on the read order data. Generate. Hereinafter, the generated slip print data is referred to as “unprinted slip data”. The slip reissue processor 223d writes the generated unprinted slip data and its identification code in the storage 23d (step S1416), and the controller 20d performs the processing from step S1402.

  When the second transmission / reception unit 24 has not received a connection request in step S1410 (step S1410: NO), or in step S1414, the print request reception unit 220 includes unprinted slip notification information in the connection request. If it is determined that there is not (step S1414: NO), the print request receiving unit 220 determines whether the second transmission / reception unit 24 has received the slip reissue request (step S1418).

  When the print request receiving unit 220 determines that the second transmission / reception unit 24 has received the voucher reissue request (step S1418: YES), the print request receiving unit 220 outputs the received voucher reissue request to the voucher reissue processing unit 223d. The slip reissue processing unit 223d acquires printer identification information and a slip number from the slip reissue request. The slip reissue processing unit 223d searches the order management data stored in the storage unit 23d by the slip number, and specifies the order data. The slip reissue processing unit 223d generates slip print data of all types of slips, that is, cooking slip print data and guest slip print data from the specified order data (step S1420).

  The slip reissue processing unit 223d outputs the generated cooking slip print data and its identification code, the generated guest slip print data and its identification code to the second transmitting / receiving unit 24, and the printer identification information acquired from the slip reissue request The second transmission / reception unit 24 is instructed to transmit to the transmission destination specified by. The second transmitting / receiving unit 24 transmits the cooking slip print data and its identification code, and the guest slip print data and its identification code to the printer 30e designated by the transmission destination (step S1422).

  The slip reissue processing unit 223d associates the identification code of the cooking slip print data transmitted in step S1422 and the identification code of the guest slip print data with the reissued flag set to on and writes it in the storage unit 23d ( Step S1424). After the process of step S1424, the controller 20d performs the process from step S1402.

  In step S1418, when the second transmission / reception unit 24 has not received the voucher reissue request (step S1418: NO), the voucher reissue processor 223d stores unprinted voucher data not yet transmitted in the storage unit 23d. It is determined whether it has been performed (step S1426).

When unprinted slip data is stored in the storage unit 23d (step S1426: YES), the slip reissue processing unit 223d determines that there is unprinted unprinted slip data, and sets an identification code of the unprinted slip data. read out.
When a plurality of unprinted slip data is stored, the slip reissue processing unit 223d reads the order time corresponding to the identification code of the unprinted slip data from the order management data, and the identification code with the earliest read order time Is read.
The slip reissue processing unit 223d determines whether or not the reissued flag set to ON is stored in the storage unit 23d corresponding to the read identification code (step S1428).

  When the slip reissue processing unit 223d determines that the reissued flag set to ON is not stored in the storage unit 23d (step S1428: NO), the unprinted slip data corresponding to the read identification code is stored. Read from the unit 23d. The slip reissue processing unit 223d outputs the read unprinted slip data and its identification code to the second transmission / reception unit 24, and instructs transmission to the transmission destination specified by the transmission destination specification information in the identification code. The second transmission / reception unit 24 transmits the unprinted slip data and the identification code input from the slip reissue processing unit 223d to the printer 30d or the printer 30e designated as the transmission destination (step S1430).

  When the second transmitting / receiving unit 24 receives a reception response from the destination printer 30d or the printer 30e within a predetermined time corresponding to the unprinted slip data transmitted in step S1430 (step S1432: YES), the slip is reissued The processing unit 223d deletes the unprinted slip data and the identification code transmitted in step S1430 from the storage unit 23d (step S1432), and the controller 20d executes the processing from step S1402. On the other hand, when the second transmission / reception unit 24 does not receive a reception response from the destination printer 30d or the printer 30e within a predetermined time (step S1432: NO), the controller 20d does not delete the unprinted slip data. The processing from step S1402 is executed.

  On the other hand, when it is determined in step S1428 that the reissued flag set to ON is stored in the storage unit 23d (step S1428: YES), the slip reissue processing unit 223d sets the read identification code. A slip deletion request is output to the second transmission / reception unit 24, and an instruction for transmission to the transmission destination specified by the transmission destination specification information in the identification code is given. The second transmission / reception unit 24 transmits a slip deletion request to the printer 30d or the printer 30e instructed to send the slip reissue request as a transmission destination (step S1436). The slip reissue processing unit 223d deletes the identification code and the unprinted slip data associated with the identification code from the storage unit 23d, and the controller 20d executes the processing from step S1402.

  In step S1426, when the slip reissue processing unit 223d determines that the unprinted slip data is not stored in the storage unit 23d and there is no unprinted unprinted slip data (step S1426: NO), the slip processing unit 222d determines whether there is slip print data for which transmission has not been completed, depending on whether slip print data for which transmission has not been completed is stored in the storage unit 23d (step S1438). When the slip print data whose transmission has not been completed is not stored in the storage unit 23d (step 1438: NO), the controller 20d executes the processing from step S1402.

When the slip print data is stored in the storage unit 23d (step S1438: YES), the slip processing unit 222d stores the slip print data that has been written in step S1408 and has not yet been transmitted and its identification code. Read from the unit 23d. The slip processing unit 222d outputs the read slip print data and its identification code to the second transmitting / receiving unit 24, and instructs transmission to the transmission destination specified by the transmission destination specifying information in the identification code.
When a plurality of slip print data is stored, the slip processing unit 222d reads the order time corresponding to the identification code of the slip print data from the order management data stored in the storage unit 23d, and the read order time is The earliest identification code and slip print data corresponding to the identification code are output to the second transmitting / receiving unit 24 to instruct transmission. The second transmission / reception unit 24 transmits the slip print data and the identification code input from the slip processing unit 222d to the printer 30d or the printer 30e designated as the transmission destination (step S1440).

  When the second transmission / reception unit 24 receives a reception response from the destination printer 30d or printer 30e within a predetermined time corresponding to the slip print data transmitted in step S1440 (step S1432: YES), the slip processing unit 222d. Deletes the slip print data and its identification code transmitted in step S1440 from the storage unit 23d (step S1444), and the controller 20d executes the processing from step S1402. On the other hand, if the second transmitter / receiver 24 does not receive a reception response from the destination printer 30d or the printer 30e within a predetermined time (step S1432: NO), the controller 20d does not delete the slip print data. The processing from S1402 is executed.

According to the present embodiment, when the power of the printer 30d is cut off and the power of the printer 30d is turned on again before the controller 20d receives a slip reissue request from another printer, A similar process is performed, and the slip print data requested to be retransmitted by the connection request is preferentially printed on the printer 30d. On the other hand, when the controller 20d receives a slip reissue request from another printer, for example, the printer 30e, before the printer 30d is turned on again, all types of slip print data having the same slip number are sent to the printer 30e. Resend and have the cooking slip and guest slip printed. As a result, when the power of the printer 30d is immediately turned on again, the cooking slip can be printed on the printer 30d without requiring the operation of the restaurant staff. On the other hand, when it takes time until the power of the printer 30d is turned on again, the cooking slip can be printed on the printer 30e by the operation of the restaurant staff, so that the cooked food can be cooked without delay.
In addition, slips that have already been printed by the printer 30e are not printed by the printer 30d after the printer 30d is turned on again. Therefore, the slip cannot be issued twice, and the person in charge of cooking is confused by the work. Never do.

  The printer 30d may include the communication processing unit 321e and the instruction input unit 37 of the printer 30e, and the printer 30e may include the deletion unit 325d of the printer 30d. Further, the printer 30d and the printer 30e may have the same configuration, and both printers may include the communication processing unit 321e and the instruction input unit 37 of the printer 30e and the deletion unit 325d of the printer 30d. Thus, when the printer 30e is powered off, the printer 30d performs the same processing as the printer 30e described above, sends a slip reissue request to the controller 20d, and returns the returned guest slip print data and cooking slip print. Print the data.

Generally, a slip number is printed on a slip, but an identification code is not printed. Therefore, the restaurant staff can know the slip number from the printed slip, but cannot know the identification code. Therefore, as described above, when the controller 20d receives a slip reissue request with a slip number set from the printer, the slip print specified by the identification code for all the identification codes associated with the slip number. Data is generated and sent to the sender of the slip reissue request. As a result, all types of slips with the slip number requested to be reissued are printed from the printer that has transmitted the slip reissue request.
Therefore, the restaurant staff may be allowed to specify which type of slip is to be printed. Specifically, as a result of the printer sending a slip reissue request, when the slip print data of all types of slips is received from the controller 20d, the printer does not show that a plurality of types of slips can be reprinted. Display on the display. When a restaurant staff inputs a type of slip to be printed, such as a cooking slip or a guest slip, into the printer, the printer prints slip print data of the input slip.

  Alternatively, if the restaurant staff knows from the beginning what type of slip is to be printed, the printer should be provided with a means for inputting information indicating the type of slip to be printed. Also good. Accordingly, the printer transmits a slip reissue request further set with information indicating the type of the input slip to the controller 20d. The controller 20d generates voucher print data only for the voucher of the type indicated by the information set in the voucher reissue request from the order data specified by the voucher number set in the voucher reissue request. Send to issuer requester. This makes it possible to print only the slip that the restaurant staff wants to print.

Alternatively, every time printing of the slip print data is completed, the printer may store the identification code of the slip print data that has been printed in the nonvolatile memory as a printed identification code. As a result, of the reissue slip print data received from the controller 20d in response to the slip reissue request transmitted by the printer, the slip print data corresponding to the printed identification code stored in the non-volatile memory of the printer itself. Only slip print data excluding is printed. For example, when the printer 20d that stores the printed identification code “0002G” in the non-volatile memory transmits a slip reissue request and acquires a lot of slip print data from the controller 20d, the identification code “0002G” is added. Print only the slip print data that is not.
This makes it possible to print only unprinted slips with the printer without forcing the restaurant staff to perform special operations.

  Alternatively, when the type of slip printed by each printer is determined, the printer that has received the slip print data of all types of slips from the controller 20d as a result of sending the slip reissue request is the type that the printer will print. Print slip print data for different types of slips. For example, when the printer 30e that prints the guest slip receives the cooking slip print data and the guest slip print data from the controller 20d in response to the slip reissue request, only the cooking slip print data is printed.

Alternatively, the controller 20d knows the type of slip printed by each printer, and when a slip reissue request is received, slip printing of a slip of a type different from the type normally printed by the printer that sent the request. Create data and send it to the printer. The printer prints the slip print data received from the controller 20d.
As a result, there is no need to provide an area for storing the printed identification code in the non-volatile memory, or to perform a writing process to the non-volatile memory during the printing process, and without forcing the restaurant staff to perform a special operation. Only the unprinted slip can be printed by the printer.

According to the above-described embodiment, it is not necessary to provide the printer with a large-capacity nonvolatile memory, and the printing process of the slip print data that has not been printed because the printer is turned off is performed with the highest priority. Therefore, slips are printed in the order of order, and it is possible to prevent a cooking instruction for a menu ordered later from being given first.
In addition, slip print data that has not been printed for some reason is preferentially printed after the printer power is turned on again, and information indicating that it was not printed last time, Printing that includes elapsed time information is possible. Therefore, it is possible to make the cook or the floor staff recognize that cooking has been delayed due to the influence of the printer, and to take appropriate measures such as urgent cooking for the slip.

  Further, when an identification code indicating that it is not slip print data is added to the print data transmitted from the controller, the printer does not record the identification code in the nonvolatile memory. Accordingly, only the identification code of the slip print data that is to be printed reliably even when the power is cut off needs to be recorded in the non-volatile memory, so that the memory capacity of the non-volatile memory can be reduced.

  The processing unit 22 of the controller 20, the processing unit 22b of the controller 20b, the processing unit 22c of the controller 20c, the processing unit 22d of the controller 20d, the processing unit 32 of the printer 30, the processing unit 32a of the printer 30a, and the processing unit 32b of the printer 30b. The processing unit 32d of the printer 30d and the processing unit 32e of the printer 30e are configured by a memory, a CPU (central processing unit), and the like. The processing unit 22 of the controller 20, the processing unit 22b of the controller 20b, and the controller 20c described above.
