[1. Overview]
In fields such as the retail industry and the wholesale industry, a JAN code is assigned to each product in order to identify each product. The JAN code is a code consisting of a country code, a manufacturer code, an item code, and a check digit code in this order. Each product has a 1: 1 relationship with the JAN code. By referring to the JAN code, it is possible to know the country of manufacture, the manufacturer, the type of product, and the like.

  Conventionally, since the numbering of the JAN code has been performed manually, there is a risk that the same code is numbered for different types of products (so-called duplicate numbering), and it takes time and effort. It was.

  Therefore, in the present embodiment, for example, a numbering control device, a numbering control method, and a numbering control program capable of preventing duplicate numbering of JAN codes and making the JAN code and each product have a unique relationship with each other are provided. doing. Further, in the numbering control device, numbering control method, and numbering control program according to the present embodiment, the country code and the manufacturer code part in the JAN code can be set for each company, so that the versatility is high. Furthermore, in the numbering control device, numbering control method, and numbering control program according to the present embodiment, the item code count-up (details will be described later) in the JAN code and the check digit code can be automatically performed. it can. Hereinafter, a specific configuration and operation will be described.

[2. Constitution]
A configuration of the numbering control apparatus 100 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating an example of the configuration of the numbering control device 100.

  The numbering control device 100 is a commercially available desktop personal computer. Note that the numbering control apparatus 100 is not limited to a stationary information processing apparatus such as a desktop personal computer, but is a portable type such as a commercially available notebook personal computer, PDA (Personal Digital Assistant), smartphone, or tablet personal computer. It may be a type information processing apparatus.

  As shown in FIG. 1, the numbering control device 100 includes a control unit 102, a communication interface unit 104, a storage unit 106, and an input / output interface unit 108. Each unit included in the numbering control device 100 is connected to be communicable via an arbitrary communication path.

  The communication interface unit 104 communicatively connects the numbering control device 100 to the network 300 via a communication device such as a router and a wired or wireless communication line such as a dedicated line. The communication interface unit 104 has a function of communicating data with other devices via a communication line. Here, the network 300 has a function of connecting the numbering control device 100 and the server 200 so that they can communicate with each other, and is, for example, the Internet or a LAN (Local Area Network). Note that data stored in the storage unit 106 to be described later may be stored in the server 200.

  An input device 112 and an output device 114 are connected to the input / output interface unit 108. As the output device 114, a speaker (including a home television), a speaker, and a printer can be used. As the input device 112, in addition to a keyboard, a mouse, and a microphone, a monitor that realizes a pointing device function in cooperation with the mouse can be used. In the following description, the output device 114 may be described as the monitor 114, and the input device 112 may be described as the keyboard 112 or the mouse 112.

  The storage unit 106 stores various databases, tables, files, and the like. The storage unit 106 stores a computer program for giving various instructions to a CPU (Central Processing Unit) in cooperation with an OS (Operating System). As the storage unit 106, for example, a memory device such as a RAM (Random Access Memory) and a ROM (Read Only Memory), a fixed disk device such as a hard disk, a flexible disk, and an optical disk can be used.

  The storage unit 106 includes a country code master 106a and a manufacturer code master 106b in which a business number is stored, an item code master 106c as a minimum free number master, and a product master 106d as a product management number master. Yes.

  Hereinafter, after describing the merchandise management number, details of each master included in the storage unit 106 will be described.

  First, the merchandise management number will be described. The product management number is a number assigned to each product so that each product and the product management number have a 1: 1 relationship. In other words, it can be said that each product and the product management number have a unique relationship. The product management number includes a business number for identifying the business and a free number that the business can freely assign to each product. Examples of the merchandise management number include a JAN code, an EAN code, a UPC code, a chassis number, a vehicle identification number, etc., but any number other than these examples as long as the number includes the business operator number and the free number. It may be a number.

  There are two types of JAN codes: a standard type consisting of 13-digit numbers and a short type consisting of 8-digit numbers. A standard type JAN code consisting of 13 digits will be described with reference to FIG. As shown in FIG. 2, the standard type JAN code consisting of 13 digits includes a country code and a manufacturer code corresponding to the company number, an item code corresponding to the free number, and a check digit (C / D ). The country code is the first or second digit number, and for Japanese companies, the number 45 or 49 is assigned. The manufacturer code is a number in the third to seventh digits, and is a number that is assigned by the distribution system development center for each company that has applied, and is used to identify each company. The item code is a number in the 8th to 12th digits, and is a number that each manufacturer (operator) can freely assign to each product, and is used to identify each product. The check digit (C / D) is a thirteenth digit number that is numbered to prevent misreading during bar code scanning. The numbering control apparatus 100 according to the present embodiment can be used in cases other than the case where the product management number is a JAN code, but in the following, for convenience of explanation, the product management number is composed of 13-digit numbers. The case of a standard type JAN code will be described.

  Next, details of each master included in the storage unit 106 will be described with reference to FIG.

  As shown in the country code in the upper part of FIG. 3, the country code master 106a stores the country code. The country code master 106a stores a number of 45 or 49 as the country code when the manufacturer is a Japanese manufacturer. The country code master 106a is an optional component, but is preferably included in the numbering control device 100 because the information is necessary when the generation unit 102a automatically generates a JAN code.

  As shown in the upper maker code in FIG. 3, the maker code master 106b stores the maker code. Normally, only one maker code master is assigned to one maker. Therefore, basically, the maker code master 106b stores only one maker code corresponding to the maker. However, for example, if the item code is used up to 99999, the item code cannot be numbered any more. In this case, the same manufacturer acquires the second manufacturer code, and the item code 00001 again. May be numbered from. In such a case, the manufacturer code master 106b stores two or more manufacturer codes. The maker code master 106b is an optional component, but is preferably included in the numbering control device 100 because the information is necessary when the generation unit 102a automatically generates a JAN code.

  As shown in the item code in the upper part of FIG. 3, the item code master 106c stores the number obtained by adding 1 to the already used free number as the minimum usable free number. For example, when a certain manufacturer has already used a free number from 00001 to 09999, the minimum available free number is 09999 + 1 = 10000. Although the minimum free number master 106c is an optional component, it is necessary information when the generation unit 102a automatically generates a JAN code. In addition, in the case of manual input, the operator can select usable item codes. Since it can grasp | ascertain efficiently and correctly, it is preferable to be included in the numbering control apparatus 100. FIG.

  Although not shown, the product master 106d stores a product management number that has already been used. For example, when the product management numbers from 4912345000018 to 4912345099998 have already been used, 9999 numbers are stored in the product master 106d.

  The control unit 102 is a CPU or the like that comprehensively controls the numbering control device 100. The control unit 102 has an internal memory for storing a control program such as an OS, a program that defines various processing procedures, and necessary data, and performs various information processing based on these stored programs. Run. In terms of functional concept, the control unit 102 includes (1) a generation unit 102a as a generation unit that generates the product management number, and (2) the generated or input product management number in the product management number master. A determination unit 102b as a determination unit that determines whether or not it exists; and (3) a registration unit 102c that registers the generated or input product management number in the product management number master if it does not exist; (4) If the free number in the product management number generated or input is the same or larger than the minimum free number, and is not present, in the generated or input product management number An update unit 102d serving as an update unit for updating the number obtained by adding 1 to the free number as a usable minimum free number in the minimum free number master; It is provided. Among these, the generating unit 102a, the registering unit 102c, and the updating unit 102d are arbitrary constituent elements. It is preferably included in the control unit 102 for the reason described in [Specific Example of Processing]. The details of the processing executed by each unit are described in [3. Specific Example of Processing] will be described in detail.

[3. Specific example of processing]
A specific example of processing according to the present embodiment will be described. In the numbering control device 100 according to the present embodiment, the numbering method for each product may be automatic numbering or numbering manually by an operator. For this reason, the automatic numbering process will be described first, and then the numbering process performed manually by the operator will be described.

  In the present embodiment, in both automatic numbering and manual numbering, as shown in the upper part of FIG. 3, the country code master 106a has the country code 49 and the manufacturer code master 106b has The maker code 12345 will be described on the assumption that 10000 is stored as the smallest free number that can be used in the item code master 106c.

[3-1. automatic numbering]
First, the case of generating the JAN code “4921235100008” by automatic numbering will be described with reference to FIGS. 4 and 5. 4 and 5 are diagrams showing an example of a flowchart in the case of automatic numbering in the numbering control process according to the present embodiment.

(Generation process)
The generation unit 102a generates the JAN code “4912345100008” by performing a generation process that combines the business operator number acquired from the storage unit 106 and the minimum free number acquired from the item code master 106c. The generation unit 102a is an arbitrary component, but is necessary for automatic numbering, and is therefore preferably included in the numbering control device 100.

  Specifically, as illustrated in FIG. 4, the generation unit 102a acquires the country code 49 from the country code master 106a (step S1), and acquires the manufacturer code 12345 from the manufacturer code master 106b (step S2). 4912345, which is a combination of these country codes and manufacturer codes, is the business number.

  Subsequently, the generation unit 102a acquires the minimum free number 10000 acquired from the item code master 106c (step S3).

  Subsequently, since this item is a process by automatic numbering, the process proceeds to NO in step S4. Subsequently, the generation unit 102a combines (integrates) the business operator number 49212345 and the minimum free number 10000 to generate an integrated code 491234510000 (step S5). And it leads to A of FIG.

  As illustrated in FIG. 5, the generation unit 102a generates a JAN code “4912345100008” by adding 8 as a check digit to the integrated code (step S6).

(Determination process)
The determination unit 102b performs a determination process for determining whether the generated JAN code “4911235100008” exists or does not exist in the product master 106d.

  As shown in FIG. 5, the determination unit 102b determines whether or not the generated JAN code exists in the product master 106d (step S7), and if it exists (in the case of YES), an error is given to the operator. (Step S8), the process is terminated.

  On the other hand, when the generated JAN code does not exist in the product master 106d (NO), the determination unit 102b proceeds to the next registration process.

(registration process)
If the registration unit 102c does not exist, the registration unit 102c performs a registration process for registering the generated JAN code in the product master 106d (step S9). Although the registration unit 102c is an arbitrary component, if the JAN code generated this time is registered in the product master 106d, the duplicate numbering is efficiently avoided by referring to the product master 106d at the next numbering. Therefore, it is preferably included in the numbering control device 100.

(Update process)
If the update unit 106d does not exist and the free number 10000 in the generated JAN code is the same as the minimum free number 10000 in the item code master 106c, the update unit 106d Update processing is performed to update 10001 in the item code master 106c, which is a number obtained by adding 1 to the free number 10000 as the smallest free number that can be used (step S10). As a result, when the JAN code is created next time, the generation unit 102a can automatically acquire 10001 that is the smallest free number that can be used from the item code master 106c and generate the JAN code. For this reason, the update unit 102d is an arbitrary component, but is preferably included in the numbering control device 100.

  After the update process is finished, as shown in the item (commodity master registration process end), the numbering control apparatus 100 ends all the automatic numbering processes.

[3-2. Manual numbering]
Next, the case of assigning the JAN code “49212345100108” by manual input will be described mainly with reference to FIGS. 3, 6, and 7. FIG. 3 is a diagram illustrating an example of a master and JAN code input screen stored in the storage unit. 6 and 7 are diagrams illustrating an example of a flowchart in the case of numbering by manual input in the numbering control process according to the present embodiment.

  An example of the JAN code input screen in the case of manual input is shown in the product number master maintenance of FIG. As shown in the product number master maintenance of FIG. 3, the input JAN code (JANCD) is 4912345100108 as described above. Note that the items on the input screen may include items such as a product code, a product name, and a JAN creation category in addition to the JAN code. In the JAN creation category item, either “0. Automatic creation” or “1. Manual input” can be selected as the JAN code creation method. If “0. Automatic creation” is selected, the above [ 3-1. When the JAN code is automatically numbered by the method described in “Automatic numbering” and “1. Manual input” is selected, the operator inputs the JAN code manually as described in this paragraph.

  In the case of numbering by manual input, the process proceeds to YES in step S4 of FIG. 4 and leads to C of FIG.

  First, as shown in FIG. 6, the numbering control apparatus 100 includes a country code 49 and a country code (12345) portion of the manually input JAN code stored in the country code master 106a and the country code 49 and It is determined whether or not the same as the manufacturer code 12345 stored in the manufacturer code master 106b (step S11).

  Unlike this example, if they are not the same (in the case of NO), the error notification in step S13 or the registration process in step S14 is performed on the manually input JAN code after the determination process in step S12 is performed. . The contents of the determination process in step S12, the error notification in step S13, and the registration process in step S14 are the same as the determination process in step S7, the error notification in step S8, and the registration process in step S9, respectively.

  On the other hand, when the numbers are the same as in this example (in the case of YES), the numbering control device 100 determines whether the free number 10010 in the manually input JAN code is the same or larger than the minimum free number 10000. Or it is determined whether it is small (step S15).

  Unlike this example, if it is small (in the case of NO) in step S15, the error notification in step S17 or the registration process in step S18 is performed for the manually input JAN code after the determination process in step S16 is performed. . The contents of the determination process in step S16, the error notification in step S17, and the registration process in step S18 are the same as the determination process in step S7, the error notification in step S8, and the registration process in step S9, respectively.

  On the other hand, as in this example, if it is large (in the case of YES) in step S15, it is connected to D of FIG. 7, and the numbering control device 100 receives the manually entered free number 10010 as shown in FIG. The item code master 106c is overwritten and updated (step S19). However, the free number 10010 is temporarily stored, and is immediately overwritten and updated to 10011 by the update process shown in step S23 described later. In the item code master in the lower right of FIG. 3, the free number is overwritten and updated to 10011 by the update process.

  In step S15, if it is large (in the case of YES), before proceeding to step S19, there is a difference in numerical values such as the manually entered free number (10010) and the minimum free number (10000) in this example, In order to avoid this, the numbering control device 100 may display a warning to the operator as to whether there is an error in the manually entered free number (10010).

  After the completion of step S19, the judgment process in step S20 is performed on the manually input JAN code, and then the error notification in step S21 or the registration process in step S22 is performed. The contents of the determination process in step S20, the error notification in step S21, and the registration process in step S22 are the same as the determination process in step S7, the error notification in step S8, and the registration process in step S9, respectively. In the determination process of step S20, the process proceeds to NO, and after the registration process of step S22 is performed, the update unit 102d adds 10011, which is a number obtained by adding 1 to the free number 10010 in the input JAN code. An update process is performed to update the minimum free number master 106c as a usable minimum free number (step S23). As a result, when inputting the JAN code next time, the operator can efficiently and accurately grasp the minimum free number 10011 that can be used. For this reason, the update unit 102d is an arbitrary component, but is preferably included in the numbering control device 100.

  After the update is completed, as shown in the item (commodity master registration process end), the numbering control apparatus 100 ends all the manual numbering processes.

  In this example, the case where the free number 10010 in the manually input JAN code is larger than the minimum free number 10000 has been described. However, the free number in the manually input JAN code is 10,000. Even in the case where it is the same as the minimum free number 10000, the process proceeds to YES in step S15 in FIG. 6 and the same processing as described above may be performed.

  As described above, in both cases of automatic numbering and numbering by manual input, according to the numbering control apparatus 100 according to the present embodiment, the generated or input JAN code is the already used JAN code. Is stored in the merchandise master 106d storing the error, an error is notified, so that duplicate numbering can be prevented.
