Therefore, the setting data in the received state can be confirmed with the setting data stored in the setting data storage area 54 and the excessive data stored in the digit- number exceeding data storage buffer 59 and on the basis of the received setting data, the setting data stored in the setting data storage area 54 can be corrected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register that performs a sales registration process when registering a product in a store or the like, and more particularly to an electronic cash register that performs data communication with another electronic cash register. Regarding

[0002]

2. Description of the Related Art Electronic cash register (hereinafter referred to simply as "register")
(Referred to as “)”, it is necessary to store product information including a product name, a unit price, and tax conditions, which is data set in advance by the operator in the registration machine. To count the registered products,
The product information must be stored for all products to be registered. If the operator tries to input the product information, it takes a long time to input the product information, and if there is a lot of product information, an input error may occur. It is necessary to correctly input each setting data included in the product information, because the registration work cannot be performed accurately unless it is correctly input.

In the case where two registration machines store the product information having the same contents as the product information stored in one of the registration machines in the other registration machine, the two registration machines are connected to each other, for example, RS-. By connecting with a cable conforming to the 232C interface standard and transmitting the product information from one registration machine to the other registration machine, it is possible to save the trouble of inputting the product information.

A technique capable of saving the trouble of data input by receiving data from another device is disclosed in Japanese Patent Laid-Open No. 5-298171. In the above-mentioned prior art, there is shown a data processing device which is used in combination with a desktop type data management device and a portable electronic notebook. When the data management device receives data from the portable electronic notebook, 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, new registration processing is performed.If the data is of the same type, a comparison is made to determine whether the update dates and times match, and if they do not match, the registered data content is received. The data has been updated. Therefore, it is not necessary to individually register / update data having the same content at a plurality of locations, and it is possible to easily and accurately register / update data in a plurality of registration areas.

[0005]

[Problems to be Solved by the Invention] When changing a registered machine at a store or when adding another registered machine in addition to the currently used registered machine, purchase a model change of the registered machine or purchase a registered machine. The registered machine in use and the newly purchased registration machine may be different models depending on budgetary requirements. Product information must be stored in advance in order to perform registration work using a registration machine, but the above-mentioned problems exist when inputting product information.

[0006] For example, by using a cable or the like conforming to the RS-232C interface standard, it is unified so that data can be exchanged between different models. However, when the number of digits of data for one set data differs between one registration machine and the other registration machine due to different models, as a first example, the registration machine that receives the data is determined in advance. When data with more digits is input, error processing such as stopping data transmission is performed. In the case of such a registration machine, since the setting data is transmitted only halfway, there is a problem that the operator has to input the setting data after the interruption, which is troublesome.

As a second example for solving the above-mentioned problems, in a registration machine in which data is stored in the 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 set to 7, if the 7th character is the same, it cannot be distinguished, and work such as confirmation of data is required, which is troublesome.

Even in an inline system in which data such as setting data is distributed from a control device that transmits one piece of data to a plurality of registered machines, the models of registered machines that make up the system are different. If the memory structure is different depending on, the accurate data transfer cannot be performed.

It is an object of the present invention to receive setting data that exceeds a predetermined number of storable digits,
An object is to provide an electronic cash register capable of storing the setting data.

When the number of digits is within a predetermined number in the product information storage means, the setting data is stored in the product information storage means. If the number of digits exceeds a predetermined number, the product information storage means is stored up to the number of digits, and the setting data portion exceeding the predetermined number of digits is stored in the excess data storage means. Therefore, even when the setting data including the number of digits exceeding the above-mentioned number of digits is received, the excess data which is stored up to the number of digits in the product information storage means and cannot be stored in the product information storage means Since the excess data is stored in the excess data storage means, it is possible to easily confirm the setting data having the number of digits exceeding the number of digits even after receiving the setting data.

Further, according to the present invention, there is provided printing means for printing the product information, wherein when the setting data in the product information is printed, the product information is printed together with the product identification information and the excess data is stored in the excess data storage means. It is characterized in that the stored setting data is provided with a printing means for printing by adding a predetermined identification code. According to the present invention, when the printing means prints the setting data stored in the product information storage means, the setting data in which the excess data is stored in the excess data storage means is added with a predetermined identification code and printed. To do. Therefore, in the setting data received by the reception processing means, it is possible to easily understand the setting data having more than the predetermined number of digits.

The present invention is also characterized in that the printing means prints setting data of a selected type among a plurality of types of setting data stored in the product information storage means. According to the present invention, the setting data of the selected type among the plural types of setting data stored in the product information storage means is printed. Therefore, it is possible to easily understand which setting data among the selected setting data exceeds the predetermined number of digits by printing only the setting data whose condition is to be stored in the product information storage means. be able to.

Further, the present invention is a printing means for printing the product information, wherein when printing the setting data in which the excess data is stored in the excess data storage means, the setting data and the product identification information are printed. It is characterized by further comprising a printing means for reading out from the product information storage means, performing printing, adding the excess data to the setting data, and printing in association with the setting data to be printed. According to the present invention, when the printing means prints the setting data in which the excess data is stored in the excess data storage means, first, the setting data and the product identification information in which the excess data are stored in the excess data storage means are stored. Is read from the product information storage means and printed. Further, excess data associated with the setting data is added to the setting data read from the product information storage unit, and the setting data is printed in association with the printed setting data. Therefore, since the setting data stored in the product information storage means and the data to which the excess data associated with the setting data is added are printed in association with each other, all the setting data are written in the product information storage means. It is possible to easily check for misleading setting data such as duplication of product names and misunderstanding due to being unable to put in.

FIGS. 9 and 10 are flowcharts for explaining the process in the reception mode in the registration machine 11 and the process after receiving the setting data. In this flowchart, the over-data buffer ADDR indicates an area for storing the address on the over-digit data buffer 59 for reading the data stored in the over-digit data buffer 59.

The over-serial number is an area for temporarily storing the serial number associated with the setting data in which the number of digits exceeds the preset number, and is used for determining whether the number of digits in the setting data is over. . "1" is set when there is no more data than the number of digits in the number-of-digits data buffer 59. In this specification, the overserial number is read from the overserial number unless otherwise specified. The serial number is an area for temporarily storing the 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 the next address of the address indicated by the reception buffer ADDR1, and item ADDR indicates each of the storage areas 84, 85, 8 indicated by the item data.
6 shows an area for storing the start address of any one of the areas. In this embodiment of the implementation, an overbuffer AD
DR, reception buffer ADDR1, reception buffer ADDR
2 and the item ADDR are, for example, the work buffer 5
8.

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 the received data is communication END data for notifying 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 one block of data is written in the reception buffer 57, and the process returns to step s1 while waiting for reception of the next data.

When it is determined in step s2 that the received data is communication END data, step s
Go to 4. In step s4, the head address of the reception buffer 57 is written in the reception buffer ADDR1. Step s5
Then, in the item data buffer, the item data indicating one of the item code setting data, the item name setting data, and the unit price setting data is written with the data at the address shown in the reception buffer ADDR1, that is, the received first block data.

In step s6, the reception buffer ADDR
1 is incremented by 1 and set to the first address of the first setting data, "001" indicating the first data of the received data is set as the serial number, and the first 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 advance in the registration machine 11, the data can be written from the leading address of the digit number over data buffer 59.

At step s7, the reception buffer ADDR
In order to set 2 to the head address of the next received data after the address indicated by the reception buffer ADDR1, the reception buffer ADDR1
The address obtained by adding 20 to the address stored in is written in the reception buffer ADDR2. As a result, even when the setting data having the maximum number of digits of 20 digits is received, the setting data can be correctly fetched without shifting the start address of each reception setting data.

In step s8, it is determined whether the received data is the product code setting data, based on the top data of the received data, that is, the item data. If the received data is product code setting data, the process proceeds to step s9. In step s9, it is determined whether the serial number is "001". If the serial number is "001", the process proceeds to step s10. At step s10, the start address of the product code setting data is written in the item ADDR so that the first data of the received setting data is written at the start 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 setting data. In step s12, the reception buffer A
The data at the address indicated by DDR1 is read and it is checked whether or not it is a NUL code, that is, "00". 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 processing of step s11 and thereafter is performed.

If the received data is not the product code setting data in step s8, the process proceeds 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 product name setting data. If it is the product name setting data, the process proceeds to step s14. Step s1
At 4, it is determined whether the serial number is "001". If the serial number is "001", the process proceeds to step s15.

At step s15, the head 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 preset product name is written in the digit number buffer. After writing the number of digits of the product name in the digit number buffer, step s12
Perform the following processing. If it is determined in step s14 that the serial number is not "001", the processes in step s16 and subsequent steps are performed.

If it is determined in step s13 that the received data is not the product name setting data, step s
Proceed to 17. This setting data is judged to be unit price setting data. When 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 preset number of digits of the unit price is written in the digit number buffer. After the number of digits of the unit price is written in the digit number buffer, the processing from step s12 is performed. If it is determined in step s17 that the serial number is not "001", the processing from step s19 onward is performed.

In step s12, the reception buffer A
When it is determined that the data of DDR1 is not the NUL 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 in the setting data storage area 54. If the beginning of the data is a NUL code, it is assumed that all the setting data have been written. Is ended, and it is determined that there is setting data that has not been written unless the beginning of the data is a NUL code.

In step s20, the read data is written in the address indicated by the item ADDR and the item ADD
The value of R is incremented by 1 and the address for writing the next setting data is set. In addition, the value of the reception buffer ADDR1 is incremented by 1,
Set the address to read the next setting data. Further, the number of digits set in the digit number buffer is decremented by 1 assuming that one digit of one setting data is transmitted.

In step s21, it is determined whether or not the result of decrementing 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 is completed, and the process proceeds to step s22. Step s22
Then, when the delimiter flag (FLG) is set to "1" and the number of digits of the received setting data exceeds the preset number of digits, "%" indicating the data delimiter in the digit number over data buffer 59. And the 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 machine 11, the data shown in the reception buffer ADDR1 is read in step s23, and the read data is NUL in step s24. Determine if it is a code. The data of the address shown in the reception buffer ADDR1 is NUL.
If it is not a code, 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.

At step s26, the delimiter code "%" and the serial number are written in the address indicated by the overbuffer ADDR in the digit number overdata buffer 59. After writing, overbuffer ADDR
The value indicated by is increased by 4 and the address at which data writing is started is set. By writing the delimiter code “%” and the serial number in the digit number over data buffer 59, the delimiter flag is cleared to “0”.

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

At step s29, the reception buffer ADD
As a result of incrementing the value of R1 by 1, it is determined whether the reception buffer ADDR1 and the reception buffer ADDR2 match. Reception buffer ADDR1 and reception buffer ADDR2
When and match, the process proceeds to step s30. In step s30, the serial number is incremented by 1 to indicate that it is the start address of the next setting data stored in the reception buffer 57, assuming that the writing of one set of the reception setting data has been completed.

As described above, one block of received data is
Since it is configured to include the 1-byte item number and 6 pieces of 20-byte setting data, the item data is inserted in 6 data units of the reception setting data.
Therefore, it is necessary to judge whether the data associated with the serial number increased by 1 is the head data for one block of the reception setting data. for that reason,
In step s31, the serial number is written as serial data in a predetermined area, and the judgment is made by the following processing.

At step s32, the serial data is converted to 6
Reduce. In step s33, it is determined whether 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 received data is the first block of the reception setting data, the reception buffer ADDR1 is incremented by 1, and the item data that is the first 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 1 setting data to set the starting address of 1 setting data ahead. After the process of step s34, the processes of step s8 and subsequent steps are performed.

If it is determined in step s33 that the serial data is not 1, the process proceeds to step s36. In step s36, it is determined whether the serial data exceeds 0. If the serial data exceeds 0, the processing 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 received data is not the start data for one block, and the value of the reception buffer ADDR2 is increased by 20 to set the start address one set data ahead. After the processing of step s37 ends, the processing of step s8 and subsequent steps is performed.

If the result of decrementing the digit number buffer by 1 is not 0 in step s21, it is considered that the writing of the number of digits preset in the registration machine 11 has not been completed, and the processing from step s20 is performed. Also, step s
When it is determined in 24 that the data of the address indicated in the reception buffer ADDR1 is the 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 machine 11,
Reception buffer ADDR which is the first address of the next setting data
The value indicated by 2 is written in the reception buffer ADDR1. After writing to the reception buffer ADDR1 is completed, step s30
Perform the following processing. When it is determined in step s25 that the delimiter flag is not "1", step s27
Perform the following processing. If the reception buffer ADDR1 and the reception buffer ADDR2 do not match in step s29, it is determined that the number is within the maximum number of digits of the reception buffer, that is, 20 digits, and therefore, the processing of step 23 and subsequent steps is performed.

In the registration machine 11, the received setting data can be combined and printed for each product to check how each setting data is stored in the setting data storage area 54.

When printing the setting data, the received product code is larger than the number of digits in the product code storage area 84,
A predetermined identification mark is added to the product code in which a part of the product code is stored in the digit number over data buffer 59 and printed. Similarly, an identification mark is also attached to the product name having a number of digits greater than the number of digits in the item name storage area 85 and the unit price configured with a number of digits greater than the number of digits in the unit price storage area 86 to print.

Therefore, in the setting data received by the registration machine 11, a part of the setting data is printed with the identification mark attached to the setting data stored in the digit number over data buffer 59. The registration machine 11 indicates that it is necessary to change the setting data for which it is difficult to recognize each setting data because it is shown only halfway.
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, the product name is selected and printed.

FIG. 11 is a diagram showing a print example when the product name setting data received by the registration machine 11 is inspected and printed. In FIG. 11A, each setting data received by the registration machine 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 identification code 101 is attached to the item of the product whose product name exceeds 7 digits. . FIG.
In (1), the serial number associated with each setting data is shown.

Since the identification code 101 is added to a product whose product name exceeds 7 digits when printing, the operator of the registration machine 11 can easily determine which product name exceeds 7 digits. be able to. Therefore, it is difficult to recognize the product name because the product name is displayed only halfway, and it is possible to confirm the data that needs to be changed.

In FIG. 11 (2), in the product name stored in the product name storage area 85, only the product name having more than 7 digits is read and printed together with the product code. Further, the data in the digit number over data buffer 59 associated with the same serial number as the serial number associated with the printed product name is read and added to the product name stored in the product name storage area 85. , The line is printed under the line of the printed product name and with the first digit aligned. That is, the first item name up to the 7th digit stored in the item name storage area 85 and the second item name received as the setting data are aligned in the first digit and are printed vertically.

Therefore, it is not only easy to confirm the product name having more than 7 digits when the data is received, but also the product name data after the 8th digit overflowing when the data is stored in the product name storage area 85 can be viewed at the same time. You can 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 flowcharts showing the process of checking and printing the setting data stored in the setting data storage area 54 in the registration machine 11.
In this flowchart, inspection 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 machine 11. The inspection print 2 is
In the setting data received by the registration machine 11, the setting data having a number of digits exceeding a predetermined number of digits is stored in the setting data storage area 54 of the registration machine 11 and the setting data in the received state are described above. This is a mode in which printing is performed in association with each other as shown in FIG.

At step p1, which inspection print is to be performed is selected. When the inspection print 1 is selected, the inspection print mode flag indicating the inspection print mode is set to "1", and when the inspection print 2 is selected, the inspection print mode flag is set to "2". After the inspection print mode is set, the process of step p2 is performed as an initial setting for performing the inspection print of the setting data on the receipt paper, for example.

At step p2, the over END flag indicating that there is no reception setting data exceeding the number of digits preset in the registration machine 11 is cleared, and the over number indicating the serial number of the reception setting data exceeding the number of digits is exceeded. As the serial number, "000" is written in the over-serial number, and "001" indicating the top setting data is set in the serial number indicating the serial number of the setting data currently being printed. This serial number matches the serial number indicating the order of setting data at the time of reception.

Next, in order to print the product code which is one item of the inspection print, 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 for printing the product name. The head address of 85 is written in the item ADDR2. Further, the 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
The top address of 9 is written in the overbuffer ADDR.

In step p3, assuming that the initial setting is completed in step p2, for example, the work buffer 5
The print buffer provided in 8 is cleared. In step p4, a process of updating the overserial number shown in the flowchart of FIG. 13 described later is performed. In step p4, if the inspection print mode flag is "1", the leading address located before the setting data with the number of digits over is set in the overbuffer ADDR, and the inspection print mode flag is "2". In this case, in the overbuffer ADDR, an address in which the setting data with the number of digits exceeded, for example, the eighth digit of the product name setting data in this embodiment is stored is set.

At step p5, it is judged which inspection print mode is selected. Inspection print mode flag is "2"
If not, the process proceeds to step p6. At step p6, the preset number of digits of the product code is written in the digit number buffer. In step p7, the print buffer 2
In order to write the product code from the digit address, the value of the print buffer ADDR that stores the address of the print buffer is incremented by 1 and the address is advanced.

At step p8, the data of the address stored in the item ADDR1 is printed in the print buffer ADD.
Transfer 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 values of the item ADDR1 and the print buffer ADDR are incremented by 1, and the respective addresses are advanced by 1. Also, the digit number buffer is decreased by one. In step p9, it is determined whether the digit number buffer has become 0 as a result of decrementing the digit number buffer by 1. Digit number buffer is 0
If not, the process from step p8 is performed. When the digit number buffer becomes 0, the process proceeds to step p10.

In 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, and the address of the print buffer is advanced by 1 to transfer the next product name. Insert a space for one digit between the code and product name. Since the transfer of the product code is completed, the product name is transferred next, and the preset digit number of the product name is written in the digit number buffer.

At step p11, the data of the start address of the product name setting data shown in the item ADDR2 is set to the address shown in the print buffer ADDR, that is, the address of the print buffer two digits ahead of the product code previously transferred. 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 1, and the address stored in each is advanced by 1. Also, the digit number buffer is decreased by one.

In step p12, it is determined whether the digit number buffer has become 0 as a result of decrementing the digit number buffer by 1. When it is determined that the digit number buffer is not 0, the processing from step p11 is performed. When it is determined that the digit number buffer is 0, the process proceeds to step p13.
In step p13, the inspection 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 the current inspection print mode is.

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

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

In step p17, the setting data written in the print buffer is printed. Step p1
In No. 8, waiting for the printing of the data in the print buffer to be completed, the data at the address indicated in the item ADDR1 is read, and it is determined whether all the setting data have been printed depending on whether the read data is a NUL code. To do. If all the setting data are not printed, the process proceeds to step p19. At step p19, the serial number is incremented by 1. After incrementing the serial number by 1, the processes from step p3 are performed.

In step p5, the inspection print mode 2
If it is determined that the value is, 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 can be printed, and the inspection print mode 2
Is completed.

In step p27, over END
If the flag is not "1", the process proceeds to step p28. In step p28, it is assumed that all the reception setting data exceeding the preset number of digits have not been printed, and in order to print the product code and the product name of the receiving setting data exceeding the next digit, the overserial Write the number to the overserial buffer. Step p29
Then, using the over-serial number written in the over-serial buffer as a counter, the item ADDR1 is set in units of a predetermined number of product codes, and the item ADDR2 is set.
The address is advanced by a predetermined number of digits of the product name, and the product code of the receiving setting data that exceeds 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. In step p30, it is determined whether or not the overserial buffer is 0. If it is determined that the over-serial buffer is 0, the processing from step p6 is performed. If it is determined that the over-serial buffer is not 0, the processing from step p29 is performed.

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

If it is determined in step p13 that the print mode is the inspection print mode 2, the process proceeds to step p20.
In step p20, the setting data written in the print buffer is printed. In step p21, the product code in the print buffer is cleared to print the reception setting data. The product name setting data exceeding the number of digits set in the registration machine 11 is stored separately in the product name storage area 85 and the digit number over data buffer 59.
Therefore, the reception setting data can be reproduced by synthesizing the product name data previously printed and the data of the digit number over data buffer 59 transferred in the following steps. In addition, by printing the received setting data at the same print digit position as the setting data, the data in the print buffer printed immediately before is retained and the number of digits over data buffer is saved at the next address of the print buffer for easy comparison. 59 is used to transfer the data.

In the print buffer ADDR indicating the address of the print buffer to which the data is transferred, 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 set at the beginning address of the print buffer. Set the address that adds the added number of digits. The leading space and the space between the product code and the product name are one digit. At step p22, the data shown in the over-buffer ADDR to be continuously transferred is read. In step p23, it is determined whether the read data is "%" which is a classification code with the data of the next exceeding digit. If the read data is not "%", the process proceeds to step p24.

At step p24, the read data is N
Determine if it is a UL code. When it is determined that the read data is not the NUL code, step p2
Go to 5. At step p25, it is judged that the read data is the data of the excess digit portion, and the read data is transferred to the address of the print buffer indicated by the print buffer ADDR. After transferring the read data, set the print buffer ADDR and the overbuffer ADDR to 1
The address to which the next data is read is increased and the address of the transfer destination is advanced by one address.

After the processing of step p25 ends, the processing of step p22 and thereafter is performed. When it is determined in step p23 that the read data is “%” and when it is determined in step p24 that the read data is the NUL code, the process proceeds to step p26. In step p26, the data written in the print buffer is printed assuming that the transfer of the data of the excess digits to the print buffer is completed. After the printing of the data written in the print buffer is completed, the processes after step p19 are performed.

FIG. 14 is a flowchart showing the update processing of the overserial number. The update of the over-serial number is performed by the inspection print 1 and the inspection print 2 in the information of the data exceeding the preset number of digits (separated data in the unit of setting data, the serial number of the data, the excess digit data). From, extract the serial number of the data that exceeds the preset number of digits,
The address of the delimiter code at the beginning of the data exceeding the number of digits is determined, and the presence or absence of data exceeding the number of digits is detected.

At step u1, the overbuffer AD
Over-digit data buffer 59 stored in DR
Read the data at the upper address. In step u2, it is determined whether the data of the address read in step u1 is a delimiter code "%". The data is "%"
In case of, the process proceeds to step u3.

At step u3, the address of the overbuffer ADDR is incremented by 1 based on the fact that the read data is the data indicating "%", and the address on the digit number overdata buffer 59 is advanced by 1. That is, the address next to the delimiter code “%” is set in the overbuffer ADDR. The data of the address on the digit over data buffer 59 stored in the over buffer ADDR is written into the over serial number by 3 bytes. The 3 bytes indicate the serial number associated with the setting data that exceeds the number of digits. Then overbuffer ADDR
Is incremented by 3, and the address on the digit number over data buffer 59 is advanced by the serial number.

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

At step u7, it is judged that the read data is the head of the setting data in which the next digit number is exceeded, and the address indicated by the overbuffer ADDR at the time of updating the next overserial number in the check print mode 1 is set. , In order to set the address where the delimiter code is stored, the overbuffer ADDR is decremented by 1, and the update of the overserial number in the check print mode 1 is completed.

If it is determined in step u2 that the read data is not data indicating a delimiter code, the process proceeds to step u8. At step u8, it is judged 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 thereafter, and the update of the overserial number is completed.

In step u4, the inspection print mode 2
If it is determined that, the update of the overserial number is ended. When it is determined in step u6 that the data does not indicate the delimiter code, step u9
Proceed to. In step u9, it is determined whether the data read in step u5 is a NUL 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 after step u5 is performed.

As described above, according to this embodiment of the present invention, even when the setting data storage area 54 receives data exceeding the storable digit number defined for each setting data, Since excess data that cannot be stored in the setting data storage area 54 is stored in the digit number excess data buffer 59, the setting data storage area 54
