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 used in the restaurant industry such as restaurants.

[0002]

2. Description of the Related Art In a conventional electronic cash register (hereinafter referred to as ECR), a calculation processing method for selling a limited number of products is disclosed in Japanese Patent Laid-Open No. 64-594.
There was one as shown in Japanese Patent Publication No. 95. In the above conventional technique, when registering a product, it is determined whether the product is registered or not. In the case of registration, the sum of the number of products sold so far and the number of products to be registered is summed up to determine whether registration is possible or not depending on whether or not the number is greater than the limited number.

[0003]

However, the above-mentioned conventional calculation processing method has the problems described in the following examples. For example, the number of items sold so far is 97
If you want to register 5 pieces, and the number you want to register is 5 pieces, and the limited number is 100 pieces, it will be impossible to register, so a customer who wants to buy 5 pieces of the product will not be able to purchase it A situation occurs in which a customer purchases three and returns. That is, for example, limit 1
Customers who came up to 00 items can not purchase,
The problem arises that customers who come later can purchase it.

Further, since only the registration mode is selected in the initial selection stage, the processing for correction processing, returned goods processing, etc. is not reflected, and it is impossible to know the exact stock number of the remaining products. Further, if the inventory is simply managed to be added at the time of return and correction, the inventory quantity will be a negative number when the inventory is centrally managed as in JP-A-4-42396.

For example, if there are 5 in stock before the return processing, 20 pieces are returned when 2 pieces are returned in the return processing. Then, at that point, there will be 25 pieces in stock, so the clerk corrects the return entry of 20 pieces, but before making the correction, if you register 10 sales at another ECR based on this 25 pieces of stock However, there was a problem that after the correction, the contradiction that the stock becomes -5 pieces occurs.

The present invention solves such a conventional problem, and when there is a request for inventory calculation processing in excess of the stock quantity, it is changed to the stock quantity at that time and the registration calculation processing (that is, sales / sales It is an object of the present invention to provide an electronic cash register which sells limited products on a first-come-first-served basis by permitting the correction processing), and changes the timing of processing inventory calculation by the sales, correction and returned goods registration processing.

[0007]

In order to achieve the above object, the present invention has means for selecting when to issue an inventory calculation processing request to an inventory calculation processing device by selling, correcting or returning goods registration processing. If there is a registration calculation processing device, and there is a stock, but a stock calculation processing request is received in a quantity exceeding the stock quantity, a means for permitting the registration calculation processing within the limited quantity and the stock quantity is "0". Inventory processing unit having means for transmitting sold-out information to the merchandise registration device and means for inputting and storing the limited number of sales, input of merchandise sale, correction and return registration process or limited number of units sold A keyboard input control device having a means for inputting the stock calculation processing, displaying the message that the stock calculation is out of stock because the requested quantity cannot be processed That means display the display control device having, also it is composed of ECR control unit and a communication cable having a means enabling connecting the respective device control.

[0008]

Operation: The stock calculation unit is set with a limited number of pre-saleable products. And in the ECR,
When executing the process for the product, if the sales registration process is in progress, the inventory calculation unit is requested to perform the inventory calculation process on the spot. After that, only when a message that permits the sale or correction registration calculation process is transmitted from the inventory calculation unit to the registration calculation unit, the registration calculation unit can sell or correct the registration calculation process. If the inventory calculation unit cannot process the requested number of inventory calculation processes and a message is sent to the registration calculation unit to change the number of registered calculation processes, the message for changing the number is displayed on the display and changed. If the registration calculation processing is performed with the specified number and the inventory calculation section is sold out and a message prohibiting the registration calculation processing is sent to the registration calculation section, a message of sold out is displayed on the display and the registration calculation processing is not performed. . If the returned goods registration process is in progress, the inventory calculation unit is requested to perform the inventory calculation process after the series of returned goods registration process is completed. Further, even if the correction registration process is performed during the return product registration process, the inventory calculation process is not requested to the inventory calculation unit on the spot.

In the stock calculation unit, the initial value is set as the sales limit number, and the subtraction process is performed in the case of the sales registration process for each process. If the obtained result is "0" or less, the state before the calculation is performed. Thus, a process of transmitting a message to the registration calculation unit that prohibits the registration calculation process due to being sold out or permits the registration calculation process under the condition that the number of pieces is changed in response to the request is performed. In addition, in the case of correction and returned goods registration processing, addition processing is performed, and then a message of permission of registration calculation processing is transmitted to the registration calculation unit. In each process, after sending the message,
Change the inventory quantity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is an ECR main body,
Slave ECRs of multiple ECRs, 2 master ECRs that perform inventory calculation processing, 3 keyboards for inputting items such as product returns and corrections, 4 display units, 5 ECs for each
It is a communication cable for connecting R.

In FIG. 1, 6 is an ECR control unit for controlling the entire ECR, 7 is a keyboard input control unit for controlling the input from the keyboard 3, and 8 is a display output control for controlling the output on the display 4. The part 9 is a registration calculation part that controls the data of product registration and other processing,
Reference numeral 10 is an inventory calculation unit that performs calculation processing of inventory data.
The registration calculator 9 executes the flow chart shown in FIG. 3, and the inventory calculator 10 executes the flow chart shown in FIG.

First, in step 11 of FIG. 3, EC
From the keyboard 1 of the R1 or ECR2, enter whether the process to be performed is sales or returns registration process
Move to 2. In step 12, product registration processing is input. In step 13, the ECR control processing unit 6 determines whether the current process is the sales registration process. Step 13
If the determination is NO in step S23, that is, if the process is the return product registration process, the process proceeds to step 25. In step 25, it is determined whether it is a return product registration process or another process. In the case of the return product registration process, the process proceeds to step 16 and the registration calculation unit 9 in ECR1 or ECR2 performs the return product calculation process.

Further, in step 13, in the case of sales registration processing, the process proceeds to step 14 to confirm whether correction registration processing or ordinary sales registration processing is included in the sales registration processing.
In the case of correction registration processing, the FLAG is set up. In addition, F
The LAG is a changeover switch provided in the electronic cash register, and the operator switches the FLAG, whereby the electronic cash register is switched to either correction registration or sales processing. Next, in step 15, in the case of ECR1, to the inventory calculation unit 10 through the communication cable 5, and in the case of ECR2, to the inventory calculation unit 10 in the same machine, the number of products to be sold and corrected and registered, A request for inventory calculation processing is made by transmitting the data of the product name and any one of the processing contents of correction processing and sales processing. Then, the processing shown in FIG. 4 is performed in the inventory calculation unit 10. When the inventory calculation unit 10 completes the processing, the data is sent to the registration calculation unit 9,
In step 16, the reply data is received. The content of the data is whether the registration calculation processing is permitted or prohibited, and whether or not there is a change in the number of inventory calculation processing requests. If there is a change, the number is also transmitted as data.

On the basis of the data obtained in step 16, the following processing is further continued in the registration calculation section 9. First, in step 17, it is determined whether or not registration calculation processing such as sales registration calculation processing and correction registration calculation processing is permitted. If the registration calculation process is permitted, the process proceeds to step 18, and it is determined whether or not the number of sales and registration processes is changed. If there is no change in this number, in step 23 the registration calculation processing is performed using the number of the stock calculation processing request as it is, and if there is a change in the quantity requested for the stock calculation processing, it is changed in the stock calculation unit 10. It is processed by the number (step 19), and the display output control unit 7 displays a message indicating that the number is changed.
It is displayed on the display 4 of R1 or ECR2.

If it is determined in step 17 that the registration calculation processing is prohibited, the message of sold-out information is displayed in ECR.
1 or 2 is displayed on the display 4, and the registration calculation unit 9
Registration processing is not executed in step 2 (step 2
4).

Step 19, Step 23, Step 2
After step 4 and step 26, move to step 20,
It waits for input whether there is a request to end the series of sales registration processing and returned goods registration processing or whether there is a request for registration processing of the next product. If there is no end request and a request for registration processing of the next product arrives, the process proceeds to step 12 and the above series of processing is repeated. When the termination request is received, the process proceeds to step 21, and it is determined whether or not the return registration process is being performed. If the return registration process is not in progress, the process ends. In the case of the return product registration process, the process proceeds to step 22 and the data of the number of products, the product name, and the processing content processed in the series of return product registration process is transmitted to the inventory calculation unit 10, and the inventory calculation unit 10 performs the registration calculation process. Receive a permission response. However, since the merchandise return registration calculation process has already been completed in step 26, the process is terminated.

FIG. 4 shows a flow chart of processing in the inventory calculation unit 10. Before the start of this series of processing, the sales limit number has already been input. Step 15 in FIG.
Alternatively, when the inventory calculation process is requested in step 22, the data transmitted in step 26 is received.

Next, in step 27, it is determined whether the processing content of the request is a sales registration processing. Here, in the case of the sales registration processing, the process proceeds to step 28, and the current inventory quantity (N) of the requested products and the requested processing quantity (n) are confirmed. Next, in step 29, the calculation of (N-n) is executed. N
In the case of -n> 0, the process proceeds to step 34, and the data that the sales registration calculation process is permitted and the requested number is not changed is transmitted to the registration calculation unit 9. After that, in step 35, the inventory data (N) is subtracted by the number of processed pieces, "N-n".
Change to When N−n <0, the routine proceeds to step 40, where it is judged whether N is positive, that is, whether there is an inventory before the request. In the case of N <= 0, in step 33, the sales registration calculation processing prohibition data is transmitted to the registration calculation unit 9. Further, in step 30, if N> 0, that is, if there is inventory but the requested quantity to be processed is greater than or equal to the current quantity in stock, the numerical value (N) changed in step 31 to enable sales registration processing is transmitted to the registration arithmetic processing unit 9 as data. .
Then, in step 32, the inventory data (N) is set to "0".
Change to

If it is determined that the process is not the sales registration process in step 27, it is determined in step 36 whether the requested processing is returned goods or correction registration process. In the case of the return or correction registration processing, the requested processing quantity (m) of the processing request product is confirmed in step 37, and a correction or return registration calculation processing possible transmission is transmitted to the registration calculation unit 9 in step 38, and then step 39. In step 1, the current inventory (N) is changed to "N + m", which is the number of processed products (m).

As described above, according to the above-described embodiment, when a sales request for more than the stock quantity is made, the sales quantity is permitted at that time, and a message notifying that the sales quantity has been changed is displayed, so that the first-come-first-served basis is guaranteed. It becomes possible to sell products in order. By changing the timing of the calculation processing request to the stock calculation processing device when the sales, correction and returned goods registration processing is performed, it is possible to calculate without causing the contradiction that the stock number becomes a negative number. Have advantages.

The present invention has the following effects, as is apparent from the above embodiment. (1) If the quantity in stock is insufficient for the quantity to be processed, the quantity to be sold is forcibly changed so that a limited number of limited sales goods can be surely sold on a first-come-first-served basis. it can. (2) By changing the timing of requesting the stock calculation processing for the sales registration processing, the correction registration processing, and the returned goods registration processing, the stock can be calculated without any inconsistency when the stock management is performed centrally.
