[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to an electronic cash register having a function of automatically registering other registered products (chain registered products) accompanying the registration of one product. Conventional Structure and Problems Generally, in the registration process of an electronic cash register, it may be necessary to register ancillary products in conjunction with the registration of one product. For example, this is the case with a set menu such as cake with coffee at a restaurant. In order to avoid the trouble of registering cake and coffee independently, there is a need for a function that automatically registers coffee when registering cake. In order to realize this function, in conventional electronic cash registers, combination registration (multi-set) information is set in advance in the preset memory as described in Japanese Patent Application Laid-open No. 10263/1983. There is a method of registering this combination by specifying a multi-set key at the time of registration. As another method, a preset memory 1 as shown in FIG. 1 has been used. Inside the preset memory 1, there are product memory files 1-1, 1-2, 1- of equal capacity.
3..., each product memory file 1-1,
1-2, 1-3... are product code areas 1-1a,
1-2a, 1-3a..., product name area 1-1b,
1-2b, 1-3b..., product unit price area 1-1
c, 1-2c, 1-3c..., chain registration product code areas 1-1d, 1-2d, 1-3d..., and each area is divided into It is configured so that each data can be preset. In addition, when registering sales by specifying the electronic cash register in registration mode, specify the product code, read the data of the product memory file from preset memory 1, and register the product. If a product code exists in the chain registration product code area in the memory file, then read the data of the product memory file for that product code from the preset memory 1 and repeat the same registration process. The system is configured to register ancillary products. Problem to be Solved by the Invention However, in the above conventional example, all product memory files in the preset memory are
It is necessary to establish a chain registration product code area.
It had the disadvantage of increasing the memory load. especially,
In recent years, as the number of product items has increased, the number of digits in product codes has also tended to increase, and the burden on the chain registration product code area in the product memory file has also tended to increase. Furthermore, since the chain registration product code area exists in the majority of product memory files that do not require chain registration products, there is a drawback that the memory cannot be used effectively. The present invention is intended to eliminate the drawbacks of the above-mentioned conventional examples, and its purpose is to provide an excellent system that has the functions of a chain registration product, avoids the increase in memory burden caused by this, and allows efficient memory utilization as a whole. To provide an electronic cash register. Means for Solving the Problems The present invention stores, in a setting mode, a product name, a product unit price, information on the presence or absence of a chain registration product in correspondence with a product code to a preset memory, and information on the presence or absence of a chain registration product in a preset memory. , means for respectively setting the chain registration product code in a part of the product name setting memory area, and in the registration mode, a product name corresponding to the registered product code from the preset memory;
A means for reading the product unit price and information on whether or not there is a chain registration product, and a means for separating the chain registration product code and the product name from the product name setting memory area of this lead data if there is a chain registration product. and a means for registering the separated chain registration product code as a new registration product code. Function: In the setting mode, the present invention stores the product name, product unit price, and information on the presence or absence of chain registration products in correspondence with the product code in the preset memory, and if there is a chain registration product, stores the chain registration product. Set each code in a part of the product name setting memory area above,
In the registration mode, information on the product name, product unit price, and presence or absence of chain registration products is read from the preset memory in accordance with the registered product code.
If there is a chain registration product, the chain registration product code and product name are separated from the product name setting memory area, the registration process is performed, and the separated chain registration product code is then added to the new registration product. As the code, information on the product name, product unit price, and presence/absence of chain-registered products corresponding to the corresponding product code is read from the preset memory and processed in the same manner as above. An embodiment of the present invention will be described below. FIG. 2 is a block diagram showing the structure of one embodiment of the electronic cash register of the present invention. In Figure 2, 1 is a replacement key, usually □0, □1,...,
□There are 10 pieces corresponding to each number of 9. 2 is a product code key, which is used to input a product code by operating the key after setting a number. 3 is a total key, which instructs calculation, display, printing, etc. of the total amount. By operating each of the numeric keys 1, the corresponding switches 4-1, 4-2, . There is. Also, keys 2 and 3
By operating each of the switches 5 and 6, the corresponding switches 5 and 6 are closed, and the respective signals are input to the arithmetic control section 7. Reference numeral 12 denotes a mode specification key for specifying the operation mode of the arithmetic control unit 7, and by operating each key 12, each switch 13-1, 13-2, 13-
3 are closed, and each operation mode of registration, inspection, and setting is designated to the arithmetic control section 7. Then, the arithmetic control unit 7 controls each key 1.
It is configured to receive the input signals of 3 to 3 and perform the arithmetic and control functions as an electronic cash register. That is, its functions include storing and reading preset data in preset data storage memory 8, storing registered data in memory 9, transferring registered data to display section 10, and transferring registered data to printing section 11. It is configured to perform the following functions. In the above embodiment, the setting example shown in Table 1 will now be taken up, and the operation of the setting mode will be specifically explained.

[Table] Switch 13-3 by mode setting key 12
When closed, the operation mode of the arithmetic control section 7 becomes the setting mode. Here, when key operation No. 1 in Table 1 is performed, the arithmetic control unit 7 searches for an empty product memory file in the preset data storage memory 8, and inputs "100" to the product code area. Store. Subsequently, when the operation No. 2 is performed, the character code "393037" corresponding to the character of cake is stored in the product main area of the same product memory file in which the product code "100" is stored. And no.
When the operation 3 is performed, the chain registration product code "216" is stored in the product name/chain registration product code combination area of the same file. Further, when the operation No. 4 is performed, 1 is stored in the chain registration product presence/absence determination area of the same file, and when the operation No. 5 is performed, "350" is stored in the product unit price area of the same file. FIG. 4 shows the internal structure of the preset data storage memory 8. In FIG. 4, the preset data storage memory 8 is divided into product memory files 8-1, 8-2, 8-3, etc. each having the same capacity, and each product memory file 8-1, 8-2,
8-3... is the product code area 8-1 respectively.
a, 8-2a, 8-3a..., product name area 8-
1b, 8-2b, 8-3b..., chain registration product presence/absence determination areas 8-1e, 8-2e, 8-3e...
…, Product unit price area 8-1c, 8-2c3, 8-
It is divided into 3c... In product name areas 8-1b, 8-2b, and 8-3b, a composite area 8 stores product names and chain registration product codes, respectively.
-1d, 8-2d, 8-3d... are provided. Figure 4 shows that following the settings for the product with product code ``100'' in Table 1, the product name and unit price have also been set for each of the products with product codes ``125'' and ``216.'' ing. Note that the products with product codes "125" and "216" do not have chain registration products, and the product name/chain registration product code combination areas 8-2d and 8-3d in each file contain only one product name. Each section is stored separately. Next, the operation of the registration mode will be explained using the registration example shown in Table 2. Note that FIG. 2 shows a part of the arithmetic control section 7 in order to explain the registration operation.

[Table] In Figures 1 and 2, mode setting key 12
When the switch 13-1 is closed, the operation of the arithmetic control section 7 becomes the registration mode. Here, as shown in Table 2, when you enter "100" using the number key 1 and operate the product code key, the arithmetic control unit 7 selects the product memory file 8 corresponding to the product code "100".
-1 is read and stored in the preset data read register 21. Since the data “1” in the chain registration product presence/absence determination area 8-1e acts to turn off the AND gate 26 through the inverter 27, only the data “cake” in the product name area b is transferred to the product name register 22. , Contents of product name/chain registered product composite area d "216"
is not transferred to the product name register 22. Next, data “350” in product unit price area c is unit price register 2.
The output of the unit price register 23 is transferred to the total register 24, and the output of the unit price register 23 is transferred to the OR gate 2.
8, 29, 30, printing section 11, display section 1
0 and are output to the registration data storage memory 9, respectively. Further, the output of the product name register 22 is also passed through the OR gates 28 and 29 to the printing section 11 and the display section 10.
Output to. As a result, "cake" shown in Table 2
350" data is displayed and printed. Furthermore, the data "100" in the product code area a is stored in the registered data storage memory 9 through the OR gate 30.
Output to. Here, since the chain registration product presence/absence determination data "1" turns on the AND gate 25, the content "216" of the product name/chain registration product code composite area d is stored in the preset data storage memory 8 through the AND gate 25. Therefore, the product memory file 8 will be output.
-3 data is read and stored in the preset data read register 21. Here, in the data in the product memory file 8-3, since the data for determining the presence or absence of chain registration products is "0", the AND gate 25 is turned off, the AND gate 26 is turned on, and the product name register 22 is filled with the product name.・The data for "Hot Coffee" will be transferred, including the data in the chain registration product code complex area.
Further, by turning off the gate 25, a new chain registration product code is not output to the preset data storage memory 8, and other circuit operations operate in the same way as the product code "100". The data for ``Hot Coffee 300'' is displayed and printed. Further, the product code "216" and the product unit price "300" are output to the registered data storage memory 9 through the OR gate 30. Next, if you enter "125" using the number keys and operate product code key 2, the data for "Orange Youth 280" will be displayed and printed in the same manner as above. At the same time, the data of the product code "125" and the product unit price "280" are output to the registered data storage memory 9. In this embodiment, in setting operation No. 4 in Table 1, the presence or absence of chain registration products is set using total key 3 and product code key 2.
In No. 3, when setting the chain registration product code "216", at the same time, the control unit 7 automatically sets the chain registration product presence determination area 8-1e in the corresponding product memory file of the preset data storage memory 8 as "1" may be stored, and in this case, the operation of No. 4 in the same table can be omitted. Effects of the Invention As explained above, in general usage conditions, the number of chain registration products is small, but in order to provide this function, a storage area for chain registration product codes is provided in the memory file for all products using the conventional method. This is because the number of digits in product codes has increased with the recent increase in the number of product items, requiring a large capacity data memory. In the cash register of the present invention, a data storage area for determining the presence or absence of chain registration products is provided in the product memory file in the preset data storage memory, and when this determination data is "1", a part of the product name area is provided. is processed as a chain registration product code, and if the main determination data is 0, the entire product name area is processed as product name data, thereby making it possible to effectively utilize the preset data memory. Since the data for determining the presence or absence of chain registration products has a capacity of 1 bit, the memory saving effect is very large. In addition, if a part of the product name area is used as a chain registration product code and there is insufficient space for setting the product name for some products, the product name setting area of the chain registration product can be used as the product name area for the product. It is possible and does not pose a problem in practice.
