DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register for performing a sales registration process at the time of merchandise registration in a store or the like, and more particularly to an electronic cash register for performing data communication with another electronic cash register. About.

[0002]

2. Description of the Related Art Electronic cash register (hereinafter simply referred to as "register")
), It is necessary to store product information including data such as a product name, a unit price, and tax conditions that are set in advance by the operator in the registration machine. To perform tallying on registered products,
The product information must be stored for all products to be registered. When the operator tries to input the product information himself, there is a problem that it takes a long time to input, and when there is a lot of product information, an input error occurs. If the setting data included in the product information is not entered without error, the registration operation cannot be performed accurately. Therefore, the setting data must be entered correctly.

[0003] In the case where two registration machines store merchandise information having the same content as the merchandise information stored in one of the registration machines, the two registration machines are connected to, for example, an RS-registered machine. By connecting with a cable or the like conforming to the 232C interface standard and transmitting the product information from one registration device to the other registration device, the trouble of inputting the product information can be saved.

Japanese Patent Application Laid-Open No. 5-298171 discloses a technique capable of saving the trouble of data input by receiving data from another device. The above prior art discloses a data processing device used in combination with a desktop data management device and a portable electronic organizer or the like. When receiving data from the portable electronic organizer, the data management device determines whether the received data is a different type of data from the data stored in the management device. If the data is of a different type, a new registration process is performed; if the data is of the same type, the data is compared to determine whether the update date and time match, and if not, the registered data content is received The data has been updated. Therefore, it is not necessary to completely register and update data of the same content at a plurality of locations, and it is possible to easily and accurately register and update data in a plurality of registration areas.

[0005]

In a store or the like, when replacing a registered machine, or when adding a registered machine in addition to the currently used registered machine, a model change of the registered machine or purchase of a registered machine is performed. Depending on the budget to be used and the like, the used registration machine and the newly purchased registration machine may be different models. Product information must be stored in advance in order to perform registration work using a registration machine, but the above-described problems exist when inputting product information.

For example, by using a cable or the like that conforms to the RS-232C interface standard, data is unified so that data can be exchanged between different models. However, in the case where the number of digits of data per set data is different due to the difference in model between the one registration machine and the other registration machine, as a first example, the registration machine on the data receiving side is preset. If data of more than the specified number of digits is input, error processing such as stopping data transmission is performed. In the case of such a registration machine, since the transmission of the setting data is performed only halfway, there is a problem that the operator must input the setting data after the interruption, which is troublesome.

In order to solve the above-mentioned problem, as a second example, for example, in a registration machine in which data is stored in storage means up to a predetermined number of digits, and data exceeding the predetermined number of digits is discarded. For example, when the predetermined number of digits is seven, if the first seven characters are the same, no distinction can be made, and work such as data confirmation is required, which is troublesome.

[0008] Even in an in-line system in which data such as setting data is distributed from a control device that transmits one data to a plurality of registration machines, the type of registration machine constituting the system is different. If the structure of the memory differs, accurate data transfer cannot be performed.

[0009] It is an object of the present invention to provide a method for receiving setting data exceeding a predetermined number of storable digits.
An object of the present invention is to provide an electronic cash register capable of storing the setting data.

[0010]

FIGS. 9 and 10 are flow charts for explaining the processing in the reception mode in registration machine 11 and the processing after receiving the setting data. In this flowchart, the over data buffer ADDR indicates an area for storing an address on the digit number over data buffer 59 in order to read data stored in the digit number over data buffer 59.

The over-serial No. is an area for temporarily storing a serial number associated with the setting data exceeding the preset number of digits, and is used to determine whether the number of digits of the setting data is over. . “1” is set when data exceeding the number of digits is not stored in the number-of-digits excess data buffer 59. In this specification, the overserial number is read from the overserial number unless otherwise indicated. The serial No. is an area for temporarily storing a serial number associated with the setting data for which the printing process is being performed.

The reception buffer ADDR1 indicates an area for storing the start address of the reception buffer 57, and the reception buffer ADDR1
DDR2 indicates an area for storing an address next to the address indicated by the reception buffer ADDR1, and an item ADDR indicates each of the storage areas 84, 85,.
86 indicates an area for storing the start address of any one of the areas 86. In this embodiment, the overbuffer A
DDR, receive buffer ADDR1, receive buffer ADD
R2 and the item ADDR are provided, for example, in the work buffer 58.

In step s1, the reception process is repeated until the reception of one block of data is completed. When the reception of the data for one block is completed, the process proceeds to step s2. In step s2, it is determined whether or not the received data is communication END data indicating the end of communication.
If the received data is not the communication END data, the process proceeds to step s3. In step s3, the received data for one block is written into the reception buffer 57, and the process returns to step s1 to wait for reception of the next data.

If it is determined in step s2 that the received data is communication END data, the process proceeds to step s2.
Proceed to 4. In step s4, the start address of the reception buffer 57 is written to the reception buffer ADDR1. Step s5
Then, the data at the address indicated by the reception buffer ADDR1 is written into the item data buffer, that is, the item data indicating any one of the product code setting data, the product name setting data, and the unit price setting data as the first data of the received one block.

At step s6, the reception buffer ADDR
1 is incremented by 1 and set as the start address of the first set data, and “001” indicating that it is the first data of the received data is set as the serial number, and the start address of the digit number over buffer 59 is exceeded. Buffer ADD
When the number of digits of the received data exceeds the maximum number of digits set in the registration device 11 in advance, the data can be written from the head address of the digit number excess data buffer 59.

At step s7, the reception buffer ADDR
2 is set as the start address of the reception data following the address indicated by the reception buffer ADDR1.
Is written to the reception buffer ADDR2. As a result, even when setting data of 20 digits, which is the maximum number of digits, is received, the setting data can be correctly loaded without shifting the start address of each reception setting data.

In step s8, it is determined whether or not the received data is product code setting data based on the first data of the received data, ie, the item data. If the received data is the product code setting data, the process proceeds to step s9. In step s9, it is determined whether or not the serial number is "001". If the serial number is "001", the process proceeds to step s10. In step s10, the head address of the product code setting data is written in the item ADDR, and the first data of the received setting data is written at the head of the product code.

In step s11, the number of digits of the product code is written in the digit number buffer in order to write the first or next set data. In step s12, the reception buffer A
The data at the address indicated by DDR1 is read, and it is checked whether it is a NUL code, that is, "00". If the data at the address indicated by the reception buffer ADDR1 is NU
If it is L, the process ends. If the serial number is not "001" in step s9, the process from step s11 is performed.

If it is determined in step s8 that the received data is not product code setting data, the flow advances to step s13. In step s13, it is determined whether or not the data stored in the item data buffer indicating the type of the received setting data is the item name setting data. If the data is product name setting data, the process proceeds to step s14. Step s1
In step 4, it is determined whether the serial number is "001". If the serial number is “001”, the process proceeds to step s15.

In step s15, the start address of the product name storage area 85 is written in the item ADDR as the first data of the product name setting data. In step s16, the number of digits of the product name set in advance is written into the number of digits buffer. After writing the number of digits of the product name in the number of digits buffer, step s12
The following processing is performed. If it is determined in step s14 that the serial number is not "001", the processes in and after step s16 are performed.

If it is determined in step s13 that the received data is not the product name setting data, the process proceeds to step s13.
Proceed to 17. This setting data is determined to be unit price setting data. If it is determined in step s17 that the serial number is “001”, the process proceeds to step s18. In step s18, since this setting data is the first data in the unit price setting data, the head address of the unit price storage area 86 is written in the item ADDR. In step s19, the number of digits of the unit price set in advance is written into the number buffer. After writing the number of digits of the unit price in the number of digits buffer, the process from step s12 is performed. If it is determined in step s17 that the serial number is not “001”, the processes in and after step s19 are performed.

At step s12, the receiving buffer A
If it is determined that the data of DDR1 is not a NULL code, the process proceeds to step s20. Step s12 is a process performed to determine whether or not all the received setting data has been written to the setting data storage area 54. If the head of the data is a NULL code, it is determined that all the setting data has been written. Is terminated, and it is determined that there is setting data that has not been written unless the head of the data is a NUL code.

In step s20, the read data is written to the address indicated by the item ADDR, and
The value of R is incremented by 1 to set an address where the next setting data is to be written. Also, the value of the reception buffer ADDR1 is increased by 1,
Set the address to read the next setting data. Further, the number of digits set in the digit number buffer is reduced by one assuming that one digit of one setting data has been transmitted.

In step s21, it is determined whether or not the result of reducing the value of the digit number buffer by 1 is 0. If the result is 0, it is determined that the writing of the set number of digits has been completed, and the process proceeds to step s22. Step s22
Then, the delimiter flag (FLG) is set to "1", and when the number of digits of the received setting data exceeds the preset number of digits, the digit number over data buffer 59 stores "%" indicating the data delimiter. And a serial number associated with the setting data is written prior to the data.

In order to determine whether or not there is data exceeding the preset number of digits in the registration unit 11, the data indicated in the reception buffer ADDR1 is read in step s23, and in step s24, the read data is NULL. Determine if it is a code. The data at the address indicated in the receive buffer ADDR1 is NULL
If not, the process proceeds to step s25. In step s25, it is determined whether the delimiter flag is set to "1". If the delimiter flag is set to "1", the process proceeds to step s26.

In step s 26, the delimiter code “%” and the serial number are written into the address indicated by the over buffer ADDR in the digit number over data buffer 59. After writing is completed, over buffer ADDR
Is increased by 4, and an address at which data writing is started is set. Since the delimiter code “%” and the serial number have been written into the digit number excess data buffer 59, the delimiter flag is cleared to “0”.

At step s27, the reception buffer ADD
The received setting data stored at the address indicated by R1 is written into the digit number over data buffer 59 indicated by the over buffer ADDR. Steps
In step 28, the value of the overbuffer ADDR is incremented by 1, and an address at which data exceeding the next digit number is written is set.
Further, the value of the reception buffer ADDR1 is incremented by 1 and an address for reading the next data is set.

At step s29, the reception buffer ADD
It is determined whether the reception buffer ADDR1 and the reception buffer ADDR2 match as a result of increasing the value of R1 by one. Receive buffer ADDR1 and receive buffer ADDR2
If they match, the process proceeds to step s30. In step s30, assuming that the writing of one piece of the reception setting data has been completed, the serial number is incremented by one to indicate that it is the start address of the next setting data stored in the reception buffer 57.

As described above, one block of received data is
Since it is configured to include a 1-byte item number and six 20-byte setting data, the item data is inserted in six data units of the reception setting data.
Therefore, it is necessary to determine whether the data associated with the serial number incremented by 1 is the first data of one block of the reception setting data. for that reason,
In step s31, the serial number is written to a predetermined area as serial data, and the determination is made by the following processing.

At step s32, the serial data is
Decrease. In step s33, it is determined whether or not the serial data is 1. If the serial data is 1, the process proceeds to step s34. In step s34, it is determined that the data is the head data of one block of the reception setting data, the reception buffer ADDR1 is incremented by 1, and the item data that is the head data of one block of the reception setting data is skipped. Further, the value of the reception buffer ADDR2 is added by 1 byte of the item data and 21 bytes which is 20 bytes of the 1 setting data, and the leading address of the 1 setting data is set. After the processing of step s34, the processing of step s8 and thereafter is performed.

If it is determined in step s33 that the serial data is not 1, the flow advances to step s36. In step s36, it is determined whether or not the serial data exceeds 0. If the serial data exceeds 0, the process from step s32 is performed. If it is determined in step s36 that the serial data is 0 or less, the process proceeds to step s37. In step s37, it is determined that the data is not the head data of one block of the reception setting data, the value of the reception buffer ADDR2 is increased by 20, and the head address of one setting data is set. After the processing in step s37 ends, the processing in step s8 and thereafter is performed.

In step s21, if the result of reducing the digit number buffer by 1 is not 0, it is determined that the writing for the preset number of digits in the registration device 11 has not been completed, and the processing from step s20 is performed. Step s
If it is determined in 24 that the data at the address indicated in the reception buffer ADDR1 is a NUL code, the process proceeds to step s35. In step s35, assuming that there is no data exceeding the number of digits set in the registration device 11,
Receive buffer ADDR, which is the start address of the next setting data
2 is written into the reception buffer ADDR1. Step s30 after writing to the reception buffer ADDR1 is completed.
The following processing is performed. If it is determined in step s25 that the separation flag is not “1”, step s27
The following processing is performed. In step s29, if the reception buffer ADDR1 and the reception buffer ADDR2 do not match, it is determined that the number of digits in the reception buffer is within 20 digits, which is the maximum number of digits in the reception buffer.

The registration device 11 can print the received setting data in combination with each product and check how each setting data is stored in the setting data storage area 54.

When the setting data is printed, if the received product code is larger than the number of digits in the product code storage area 84,
A product code in which a part of the product code is stored in the digit number over data buffer 59 is printed with a predetermined identification code added thereto. Similarly, a product name composed of more digits than the product name storage area 85 and a unit price composed of more digits than the unit price storage area 86 are also printed with identification marks.

Accordingly, in the setting data received by the registration device 11, a part of the setting data is printed with the identification mark attached to the setting data stored in the digit number excess data buffer 59. The registration unit 11 informs the user that the setting data, which is difficult to recognize because the setting data is only displayed halfway, needs to be changed.
Can be recognized by the operator. When printing the setting data, the setting data can be selected from a plurality of setting data and printed. In this embodiment of the present invention, a product name is selected and printed.

FIG. 11 is a diagram showing a printing example when the registration setting device 11 checks and prints the product name setting data received. In FIG. 11A, each setting data received by the registration device 11 and stored in the setting data storage area 54 is printed. The product code and the product name, which are the setting data stored in the product code storage area 84 and the product name storage area 85, are printed, and the item of the product whose product name exceeds seven digits is provided with the identification code 101. . FIG.
In (1), a serial number associated with each setting data is shown.

Since the identification code 101 is added to a product whose product name exceeds seven digits when printing, the operator of the registration machine 11 easily determines which product name has more than seven digits. be able to. Therefore, it is difficult to recognize the product name because the product name is shown only partway, and it is possible to confirm data that needs to be changed.

In FIG. 11 (2), only the product names having more than 7 digits are read out from the product names stored in the product name storage area 85 and printed together with the product code. Further, the data in the number-of-digits excess data buffer 59 associated with the serial number corresponding to the printed product name is read and added to the product name stored in the product name storage area 85. Then, the printed item name is printed one line below and with the first digit aligned. That is, the first item name up to the seventh digit stored in the item name storage area 85 and the second item name when received as setting data are aligned with the first digit, and printed vertically.

Therefore, not only is it easy to confirm the product name exceeding 7 digits when data is received, but also the product name data after the 8th digit that overflows when stored in the product name storage area 85 is simultaneously viewed. Can be. The product name stored in the product name storage area 85 can be changed based on the product name at the data transmission source.

FIGS. 12 and 13 are flow charts showing the processing when the registration machine 11 checks and prints the setting data stored in the setting data storage area 54.
In this flowchart, check print 1 is a mode for printing the result of storing the received setting data in the setting data storage area 54 of the registration device 11. Inspection print 2
In the setting data received by the registration device 11, the result of storing the setting data having a number of digits exceeding a predetermined number of digits in the setting data storage area 54 of the registration device 11 and the setting data in the received state are described above. This is a mode for printing in association with each other as shown in FIG.

In step p1, which check printing is to be performed is selected. When the check print 1 is selected, the check print mode flag indicating the check print mode is set to “1”, and when the check print 2 is selected, the check print mode flag is set to “2”. After the check print mode is set, the process of step p2 is performed as an initial setting for checking and printing setting data on, for example, receipt paper.

At step p2, the over END flag indicating that there is no reception setting data exceeding the preset number of digits in the registration device 11 is cleared, and the over end indicating the serial number of the reception setting data exceeding the number of digits is cleared. “000” is written in the over serial number as a serial number, and “001” indicating the leading setting data is set in the serial number indicating the serial number of the setting data currently being printed. The serial number matches the serial number indicating the order of the setting data at the time of reception.

Next, in order to print the product code, which is one item of inspection printing, the head address of the product code storage area 84 in the setting data storage area 54 is written in the item ADDR1, and the product name storage area is used to print the product name. The first address of the address 85 is written in the item ADDR2. Further, a digit number over data buffer 5 storing the serial number of the reception setting data exceeding the number of digits and the reception setting data exceeding the number of digits.
9 is written to the overbuffer ADDR.

At step p3, assuming that the initialization has been completed at step p2,
8 is cleared. In step p4, a process of updating the over serial number shown in the flowchart of FIG. 13 described below is performed. At step p4, if the check print mode flag is "1", the first address located before the set data whose number of digits is exceeded is set in the overbuffer ADDR, and the check print mode flag is "2". In this case, in the overbuffer ADDR, an address where the number of digits of the setting data which exceeds the number of digits, for example, the address of the eighth digit of the product name setting data in this embodiment is set.

At step p5, it is determined which inspection printing mode is set. Check print mode flag is "2"
If not, proceed to step p6. In step p6, the number of digits of the product code set in advance is written into the number of digits buffer. At step p7, the print buffer 2
In order to write the product code from the address of the digit, the value of the print buffer ADDR for storing the address of the print buffer is increased by 1 and the address is advanced.

At step p8, the data of the address stored in the item ADDR1 is stored in the print buffer ADD.
The data is transferred to the address indicated by R, that is, the address of the second digit of the print buffer. When one digit of the product code is transferred to the print buffer, the value of the item ADDR1 and the value of the print buffer ADDR are increased by one, and each address is advanced by one. In addition, the digit number buffer is reduced by one. In step p9, it is determined whether or not the digit number buffer has become 0 as a result of reducing the digit number buffer by one. Number of digits buffer is 0
If not, the processing after step p8 is performed. When the digit number buffer becomes 0, the process proceeds to step p10.

At step p10, the value of the print buffer ADDR is incremented by 1 assuming that all of the product codes have been transferred to the print buffer, thereby increasing the address of the print buffer by one to transfer the next product name. Insert a space for one digit between the code and the product name. Since the transfer of the product code is completed, the process proceeds to the transfer of the product name, and the preset number of digits of the product name is written in the number buffer.

In step p11, the data of the head address of the product name setting data indicated in the item ADDR2 is stored in the address indicated in the print buffer ADDR, that is, the address of the print buffer two digits ahead of the previously transferred product code. Forward. When one digit of the product name is transferred to the print buffer, the value of the item ADDR2 and the value of the print buffer ADDR are incremented by one, and the address stored in each is advanced by one. In addition, the digit number buffer is reduced by one.

At step p12, it is determined whether or not the number buffer becomes 0 as a result of reducing the number buffer by one. When it is determined that the digit number buffer is not 0, the process from step p11 is performed. When it is determined that the digit number buffer is 0, the process proceeds to step p13.
At step p13, the check print mode is confirmed assuming that all the product names have been transferred to the print buffer. That is, it is determined which inspection print mode is the current inspection print mode.

If the mode is the inspection print mode 1, the process proceeds to step p14. At step p14, it is determined whether or not an over-END flag indicating that there is no reception setting data exceeding the preset number of digits in the registration device 11 is set. If the over END flag has not been set, the process proceeds to step p15. Step p
In step 15, in order to determine whether or not the product code and product name transferred to the print buffer immediately before are reception setting data exceeding the set number of digits, it is determined whether the serial number and the over serial number match. to decide.

If the serial number and the over serial number match, the process proceeds to step p16. If the serial number and the over-serial number match, in step p16, to indicate that the product code and the product name transmitted immediately before are the reception setting data exceeding the preset number of digits, “%” Indicating that the reception setting data exceeds the number of digits is transferred.

At step p17, the setting data written in the print buffer is printed. Step p1
In step 8, the CPU waits for the printing of the data in the print buffer to be completed, reads the data at the address indicated by the item ADDR1, and determines whether all the setting data has been printed based on whether the read data is a NULL code. I do. If all the setting data has not been printed, the process proceeds to step p19. At step p19, the serial number is incremented by one. After the serial number is incremented by one, the processing after step p3 is performed.

In step p5, check print mode 2
If it is determined that the above is true, the process proceeds to step p27. In Step p27, it is determined whether or not the over END flag is “1”. If the over END flag is “1”, it is assumed that all the reception setting data exceeding the preset number of digits has been printed, and the inspection printing mode 2
Is completed.

In step p27, over END
If the flag is not "1", the flow proceeds to step p28. In step p28, assuming that all of the reception setting data exceeding the preset number of digits has not been printed, the product code and product name of the next reception setting data exceeding the number of digits are overprinted. Write the number to the overserial buffer. Step p29
Then, the item ADDR1 is set in units of a predetermined number of digits of the product code using the overserial number written in the overserial buffer as a counter.
The address is advanced by a predetermined number of digits of the product name, and the product code of the reception setting data exceeding the next number of digits, the item ADDR1 and the item A are added to the address of each setting data storing the product name.
Set DDR2. At Step p30, it is determined whether or not the overserial buffer is 0. If it is determined that the value of the overserial buffer is 0, the process from step p6 is performed. If it is determined that the value of the overserial buffer is not 0, the process from step p29 is performed.

When it is determined in step p14 that the over-END flag is 1, and when step p1
If it is determined in step 5 that the serial number is not the same as the over serial number, the process from step p17 is performed.

If it is determined in step p13 that the mode is the inspection print mode 2, the process proceeds to step p20.
At step p20, the setting data written in the print buffer is printed. At step p21, the product code in the print buffer is cleared in order to print the reception setting data. The item name setting data exceeding the number of digits set in the registration device 11 is separately stored in the item name storage area 85 and the digit number over data buffer 59.
Therefore, the reception setting data can be reproduced by synthesizing the previously printed item name data and the data of the digit number over data buffer 59 to be transferred in the following steps. Also, by printing the reception setting data at the same print digit position as the setting data, the data of the print buffer printed immediately before is retained so that comparison can be easily performed. A method of transferring 59 data is used.

In the print buffer ADDR indicating the address of the print buffer for transferring data, the number of digits of the product code, the number of digits of the product name, the leading space, and the space between the product code and the product name are added to the start address of the print buffer. Set the address to which the number of added digits is added. The leading space and the space between the product code and the product name are one digit. At step p22, the data indicated in the overbuffer ADDR to be subsequently transferred is read. At step p23, it is determined whether or not the read data is "%" which is a division code with the data of the next extra digit part. If the read data is not "%", the flow proceeds to step p24.

At step p24, the read data is N
It is determined whether it is a UL code. If it is determined that the read data is not a NULL code, the process proceeds to step p2.
Go to 5. In step p25, it is determined that the read data is the data of the digit portion exceeding the read data, and the read data is transferred to the address of the print buffer indicated by the print buffer ADDR. After transferring the read data, the print buffer ADDR and the over buffer ADDR are set to 1
The address is increased and the next data read address and the transfer destination address are advanced by one address.

After the processing of step p25 is completed, the processing of step p22 and thereafter is performed. If it is determined in step p23 that the read data is "%", and if it is determined in step p24 that the read data is a NULL code, the process proceeds to step p26. At step p26, the data written in the print buffer is printed assuming that the transfer of the data of the excess digit to the print buffer has been completed. After the printing of the data written in the print buffer is completed, the processing after step p19 is performed.

FIG. 14 is a flowchart showing the process of updating the overserial number. The over-serial number is updated by checking information of data exceeding the preset number of digits in the check print 1 and the check print 2 (separation data of set data unit, data serial number, data of the exceeded digit). From, extract the serial number of the data exceeding the preset number of digits,
The address of the delimiter code at the beginning of a plurality of data exceeding the number of digits is determined, and the presence / absence of data exceeding the number of digits is detected.

At step u1, the overbuffer AD
Number of digits over data buffer 59 stored in DR
Read the data at the upper address. In step u2, it is determined whether or not the data at the address read in step u1 is a delimiter code "%". The data is "%"
To go to step u3.

In step u3, the address of the over buffer ADDR is incremented by one based on the fact that the read data is data indicating "%", and the address on the digit number over data buffer 59 is advanced by one. That is, the address next to the delimiter code “%” is set in the overbuffer ADDR. The data at the address on the number-of-digits overdata buffer 59 stored in the overbuffer ADDR is written into the overserial number for three bytes. The three bytes indicate a serial number associated with setting data exceeding the number of digits. Then over buffer ADDR
Is incremented by 3, and the address on the number-of-digits-over data buffer 59 is advanced by the serial number.

At step u4, it is determined whether the check print mode flag is "1" and the current check print mode is confirmed. If the mode is the inspection print mode 1, the process proceeds to step u5. In step u5, the overbuffer AD
The data at the address indicated by DR is read, and the value of the overbuffer ADDR is incremented by one. In step u6, it is determined whether or not the data read in step u5 is data indicating a delimiter code "%". If the data is data indicating a delimiter code, the process proceeds to step u7.

In step u7, it is determined that the read data is the head of the set data whose number of digits exceeds the next digit, and the address indicated by the over buffer ADDR at the time of the next update of the over serial number in the inspection print mode 1 is determined. Then, the overbuffer ADDR is decremented by one in order to set the address where the delimiter code is stored, and the update of the overserial number in the inspection print mode 1 is completed.

If it is determined in step u2 that the read data is not data indicating a delimiter code, the flow advances to step u8. At step u8, it is determined that the read data is a NUL code, and the over END flag is set to "1". That is, it indicates that there is no data exceeding the number of digits, and the update of the overserial number ends.

In step u4, check print mode 2
If it is determined that the serial number is over, the update of the overserial number ends. If it is determined in step u6 that the data is not data indicating a delimiter code, step u9 is performed.
Proceed to. In step u9, it is determined whether or not the data read in step u5 is a NULL code. If it is a NUL code, it is determined that there is no data exceeding the number of digits thereafter, and the processing from step u7 is performed. If it is determined that the code is not the NUL code, the processing from step u5 is performed.

As described above, according to this embodiment of the present invention, even when data exceeding the number of storable digits defined for each set data in the set data storage area 54 is received, Excess data that cannot be stored in the setting data storage area 54 is stored in the number-of-digits excess data buffer 59.
The setting data in the received state can be confirmed by the setting data stored in the setting data storage portion and the excess data stored in the digit number excess data buffer 59, and stored in the setting data storage area 54 based on the reception setting data. The setting data that has been set can be corrected.

When the data stored in the setting data storage area 54 is printed using the printer 17, the identification code 101 is added to the data whose data is stored in the number-of-digits-overdata buffer 59. Is performed, it is possible to easily understand which data has a predetermined number of digits or more.

Further, the excess setting data is stored in the number-of-digits excess data buffer 59, and the setting data of the number of digits that can be stored in the setting data storage area 54 and the setting data of the number of digits that are stored in the setting data storage area 54 And the data obtained by combining the setting data and the excess setting data corresponding to the setting data stored in the number-of-digits-over-data buffer 59 are arranged vertically, and the leading position of the data is aligned. 17, the data stored in the setting data storage area 54 can be compared with the data received by the registration device 11, and the data such as the product name due to the failure to write all the setting data can be compared. It is easy to check for confusing data that may cause duplication or misunderstanding. Further, the stored data can be compared with the received data, so that the stored data can be easily and accurately corrected.

[0106]

As described above, according to the present invention, even when the electronic cash register receives setting data having a number of digits exceeding a predetermined number of digits, it can be stored in the product information storage means. Since the excess setting data that cannot be stored is stored in the excess data storage means,
The setting data portion exceeding the number of digits can be referred to, and the setting data stored in the product information storage unit can be appropriately corrected.

Further, when the setting data in the product information is printed, the setting data in which the excess data is stored in the excess data storage means is printed with a predetermined identification code added thereto. Can be easily understood whether or not is composed of data of a predetermined number of digits or more, and it can be recognized which set data needs to be corrected. The setting data can be appropriately corrected by referring to the print result.

Further, according to the present invention, when printing the setting data in the product information, the setting data of the selected type among the plurality of types of setting data stored in the product information storage means is printed. By printing only the setting data that the operator wants to check, it is possible to check which setting data exceeds the predetermined number of digits, and the setting data can be corrected efficiently.
