Description

Description: FIELD OF THE INVENTION The present invention relates to an electronic cash register capable of processing discounts on merchandise for sale.

[Prior Art] Conventionally, in the case of discounting sales products, in an electronic cash register having a sales memory for accumulating sales of registered products by division, individual product, etc.
Immediately after registering the sale of the product, specify the discount amount and operate the discount key. By doing so, the specified discount amount is subtracted from the sales memory to which the sales data is added by the sales registration, and the actual sales can be obtained in the sales memory.

By the way, conventionally, as means for registering n (n ≧ 2) pieces of the same product for sale, so-called repeat registration in which the code of the product is continuously input n times, and one piece after n is designated as the multiplication number There is so-called multiplication registration for performing sales registration. A normal electronic cash register has at least one registration function.

[Problems to be Solved by the Invention] However, when a plurality of identical products to be registered for sale are discounted, the code of the product is entered once in the electronic cash register having the repeat registration function. Specify the discount amount for each one and operate the discount key or calculate the total discount amount by multiplying the discount amount per unit by the sales quantity and specify the total discount amount immediately after repeat registration By operating the discount key, discounts for multiple products were processed.

Further, also in the electronic cash register having the multiplication registration function, the total discount amount is calculated by multiplying the discount amount per piece by the sales quantity, and immediately after the multiplication registration, the total discount amount is designated and the discount key is operated. By doing so, discounts for multiple products were processed.

As described above, in the past, when a plurality of the same products to be registered for sale were discounted, the same key operation was repeated, which was troublesome, and the total discount amount had to be calculated by arithmetic calculation. Not only was it large, but there was a problem that registration work could not be carried out smoothly.

Therefore, according to the present invention, even if a plurality of the same products to be registered for sale are discounted, the discount process for each product can be performed with a simple key operation, the burden on the cashier can be reduced, and the registration work can be performed smoothly. It is intended to provide an electronic cash register which can be optimized.

[Means for Solving the Problem] The present invention relates to an electronic cash register having a repeat registration function, a registration counter for counting the number of repeat registrations, and a discount key for designating discount data.
A discount processing control means for repeating the discount processing by the discount data designated by the discount key operation after the repeat registration by the count number of the registration counter is provided.

Further, according to the present invention, in an electronic cash register having a multiplication registration function, a registration counter for storing a multiplication number, a discount key for designating discount data, and a discount key operation after registration for multiplication are designated. A discount processing control means for repeating the discount processing based on the discount data by the number of counts of the registration counter is provided.

[Operation] In the case of the electronic cash register taking the former measure, if a plurality of the same products are targeted for discount, by specifying the discount data for one product after repeat registration and operating the discount key. The discount processing based on the discount data designated by the number of repeat registrations counted by the registration counter is repeated.

Further, in the case of the electronic cash register taking the latter means, when a plurality of the same products are targeted for discount, by designating the discount data for one product after registering multiplication and operating the discount key, The discount processing is repeated by the discount data designated by the multiplication number stored in the registration counter.

In addition, the keyboard 15 is a control key 31 operated by a key for controlling power on / off and selecting various business modes such as “registration”, “payment”, and “setting”.
Is provided.

As shown in FIG. 3, the RAM 14 stores a department memory 32 for accumulating the sales points and sales amounts of the products belonging to each department for each department code for classifying each product, and the total amount of the products purchased by one customer. A customer totalizer 33 for calculating is formed.

Further, as shown in the figure, a register register for temporarily storing the register data, a sales number area for storing the sales number of the sales registration product, a registration code area for storing the department code of the sales registration product, and a discount for the sales registration product. Memory 34 that includes a discount amount area that stores the sales amount, a sales amount area that stores the sales amount of a registered product for sale, and a registration counter that stores the number of times of registration of the same product, and a customer value that accumulates the number of times of discounts for one discount operation. The discount number area, the customer discount amount area for accumulating the discount amount for one discount operation, the total discount frequency area for accumulating the discount number for all products registered for sale in this electronic cash register, and the same for all A memory 35 consisting of a total discount area for accumulating product discounts, a registration flag set to “1” during sales registration, and a multiplication flag set to “1” during multiplication registration. An arithmetic flag memory 36 and the like are formed.

Then, the CPU 11 allows the input of key data from the keyboard 15 after executing a predetermined initial process by turning on the power. If the key data input from the keyboard 15 is the numerical key 23 while the "registration" mode is selected by the control key 31, it corresponds to the key data as shown in FIG. The numeric data is stored in the numeric register and the contents of the numeric register are displayed on the display unit 17.

On the other hand, if the key data input from the keyboard 15 is due to the multiplication key 30, after confirming that the number data is stored in the number register as shown in FIG. 5,
This numerical data is transferred to the sales point area and the multiplication flag is set to "1".

When the "registration" mode is selected by the control key 31 and the key data input from the keyboard 15 is data by the department key 24, the CPU 11 executes the department key processing shown in FIG. That is, the state of the multiplication flag is checked as P1. Then, if the multiplication flag is set to "1", it is recognized as multiplication registration, and it is confirmed that the number data is stored in the number register as P2. Then, as P3, store the department code corresponding to the input key data in the registration code area, and as P4, calculate the sales amount by multiplying the point data in the sales point area and the number data in the number register. Store the amount data in the sales amount area. Then, as P5, the department code in the registration code area and the sales amount in the sales amount area are displayed on the display unit 17. Also, as P6, the score data in the sales score area is set in the registration counter.

Next, as P7, the department memory 32 is searched to find the sales points and sales amount that match the department code in the registration code area, and the sales points in the store number area are added to the above sales points. The sales amount in the area is added to the above sales amount. Further, as P8, the sales amount in the sales amount area is added to the customer totalizer 33. In addition, P9
As a result, the printer 19 is driven to print out the department code in the registration code area, the number of sales points in the sales number area, and the sales amount in the sales amount area on a receipt. After a while
As P10, the multiplication flag is cleared to "0" and the registration flag is set to "1".

On the other hand, when the multiplication flag is cleared to "0" at P1, it is checked as P11 whether or not the numerical register data is stored in the numerical register 34. Then, if it is stored, it is recognized that it is a sales registration of one product, and [score data = 1] is stored in the sales score area as P12. Then, as P13, the department code corresponding to the input key data is stored in the registration code area, and as P14, the number data in the number register is transferred to the sales amount area. And
As P15, the department code in the registration code area and the sales amount in the sales amount area are displayed on the display unit 17. Also,
As P16, set [Point data = 1] in the sales point area to the registration counter. Then, the processes of P7 to P10 are executed.

If no data is stored in the number register in P11, it is determined in P17 whether the department code corresponding to the input key data matches the department code in the registration code. If they do not match, an error occurs.
On the other hand, if they match, it is recognized as repeat registration and the count value of the registration counter is set to "+" as P18.
Update only 1 ”. Then, the processes of P7 to P10 are executed.

When the "registration" mode is selected by the control key 31 and the key data inputted from the keyboard 15 is the discount key 27, the CPU 11 executes the discount key processing shown in FIG. That is, the state of the registration flag is checked as P21. Then, when the registration flag is set to "1", it is checked as P22 whether or not the number data is stored in the number register. And
When it is stored, the number data in this number register is transferred to the discount area as P23. In contrast,
If the registration flag is cleared to "0" at P21, or if the number data is not stored in the number register at P22, an error occurs.

After transferring the data to the discount area in P23, search the department memory 32 in P24 to find the sales point and sales amount that match the section code in the registration code area, and subtract "-1" from the sales point. At the same time, the discount amount in the discount amount area is subtracted from the sales amount. Further, as P25, the discount amount in the discount amount area is subtracted from the customer totalizer 33. Furthermore, as P26, "+1" is added to the data in the customer discount frequency area.
And the data in the discount area is added to the data in the customer discount frequency area. Then, as P27, the count value in the registration counter is decremented by "-1". Then, as P28, the count value of the registration counter is "0".
Repeat the process from P24 to P27 until it becomes.

Then, as P29, the contents of the customer discount number area are added to the total discount number area, and the contents of the customer discount amount area are added to the total discount amount area. Also, the printer 19 is driven as P30, and the contents of the customer discount amount area are printed out as a discount amount on a receipt. Then, as P31, the discount area,
Clear the customer discount count area and customer discount area.

Further, when the "registration" mode is selected by the control key 31 and the key data input from the keyboard 15 is the deposit / cash total key 26, the registration flag is set to "1". After confirming that, customer totalizer
The total amount of money in 33 is displayed on the display unit 17 and is printed out on the receipt. Then issue a receipt and draw
Release 21. Then, the registration flag is cleared to "0".

In the present embodiment having such a configuration, when registering a plurality of sales of the same merchandise to be discounted, the cashier selects whether to perform repeat registration or multiplication registration. Then, in the case of repeat registration, after registering the normal sales amount for each product, the department key to which the product belongs is entered. Then, the same department key is continuously input for the number of registered items. Then, the sales by the normal sales amount are cumulatively processed in the department memory 32 and the customer totalizer 33 corresponding to the input department key, and the number of repeat registrations is counted in the registration counter.

Then, the cashier enters the discount key 27 after entering the discount amount per item of the product. Then, the discount processing by the discount amount is repeated for the department memory 32 and the customer totalizer 33 by the number of times of the registration counter, and the cumulative discount amount by this repetition is a numerical value for a plurality of the discount target products. It is printed out on the receipt as a discount.

Therefore, it is possible to collectively process the discounts for the plurality of repeat-registered same products by a key operation equivalent to the normal discounting operation for one product.

On the other hand, if you want to carry out sales registration for multiple identical products that are the target of discount by multiplication registration, enter the multiplication key 30 after entering the number of the products, and then enter the normal sales amount for each product. After entering the number, enter the department key to which the product belongs. Then, the number of products is multiplied by the normal sales amount to calculate a plurality of sales amounts, and the sales amount corresponds to the input department key. The department memory 32 and the customer totalizer 33
Is treated as a total. At this time, the number of keys input is set in the registration counter.

Then, the cashier enters the discount key 27 after entering the discount amount per item of the product. Then, the discount process by the discount amount is repeated for the department memory 32 and the customer totalizer 33 by the number of times of the registration counter, and the cumulative discount amount by this repetition is the total amount for a plurality of the discount target products. It is printed out on the receipt as the discount amount.

Therefore, it is possible to collectively process the discounts for a plurality of the same products for which multiplication registration has been performed, by a key operation equivalent to the normal discounting operation for one product.

As described above, according to the present embodiment, a discount operation can be processed for a plurality of identical products that have undergone repeat registration or multiplication registration by a simple key operation equivalent to a normal discount operation for one product. The operation of can be simplified. Moreover, there is no need to calculate the total discount by mental calculation. Therefore, the burden on the cashier can be reduced, and the registration work can be facilitated.

In the above-mentioned embodiment, the case where the invention is applied to the electronic cash register which manages the sales data of the sold products by the department registration is shown. However, even if the sales are managed by the single item registration, the class registration, etc. Needless to say. Further, in the above-described embodiment, the case where the discount amount is directly inputted by the key is shown, but the same is true when the discount rate is inputted by the key and the discount amount for the sales amount is automatically calculated and discounted. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, even when a plurality of identical products to be registered for sale are registered by repeat registration, the discount for each product can be obtained by a simple key operation. It is possible to provide an electronic cash register capable of performing processing, reducing the burden on the cashier, and facilitating registration work.

Further, according to the present invention, the same effect can be obtained even when a plurality of identical products to be registered for sale are registered as products for discounting by multiplication registration.
