It consists of a department registration flag area 257 indicating the department registration flag area 257. Further, in the department registration flag area 257, when the department is registered, ■ is set, otherwise it is set to O. The registration flag 29 is set when registration is performed, the sequential discount flag 30 is set when the privilege key 19 is input before registration, and the lump sum discount flag 31 is set when the privilege key 19 is input after registration. Set when there is input. Both flags are cleared during the closing process.

FIGS. 5 to 7 are flowcharts showing each process of this embodiment.

FIG. 5 is a flowchart showing the registration process.

The key operations for the registration process are to specify a product code using the numeric keypad 17 and specify a department using the department key 18. This flowchart is executed when an input is received from the keyboard 2.

If there is human power on the keys, it is determined in step 100 whether the input key is the numeric keypad 17, and if the input is on the numeric keypad 17, the input data is stored in a work buffer (not shown) in step 101. If the key is not tinkey 17, it is determined in step 102 whether it is the department key 18, and if the department key is 18, department processing is performed in step 103. This process will be explained as a subroutine with reference to FIG. If it is not a department key, it is determined in step 104 whether it is a preferential key 19, and the preferential key 19 is determined.
If so, the registration flag 29 is checked in step 105 to determine whether registration is in progress. If the registration flag 29 is not set, it means that the product has not been registered yet, so the discount flag 30 is successively set to 1 in step 106. If the registration flag 29 is set, it means that the registration has already been made, so in order to apply the discount all at once, proceed to step 1.
In step 07, the bulk discount flag 31 is set to 1. If it is not the benefit key 19, it is determined in step 108 whether it is the subtotal key 20, and if it is the subtotal key 20, subtotal processing is executed in step 109. This process will be explained as a subroutine with reference to FIG. If the subtotal key is not 20, it is determined in step 110 whether it is the close key 21, and if it is not the close key 21, it is determined in step 116.
to perform other processing. If it is the close key 21, it is determined in step 1ll whether the subtotal flag 32 is set, and if it is not set, it is an operational error on the part of the cashier and the process is skipped. If the subtotal flag 32 is set, change is calculated from the deposit amount and the registered amount per customer in step 111 and displayed on the display 5, and step 1
At step 13, the R/J printer 14 prints out each customer's registration information, deposit amount, and change. In step 114, memory processing such as adding the data in the single customer department sales area 256 to the total sales area 254 of the corresponding department is performed, and in step 1
At step 15, various flags are cleared and the process ends.

FIG. 6 is a flowchart of the department processing at step 103 in FIG.

First, in step 117, the subtotal flag 32 is cleared.

This is to accommodate additional registration after the subtotal. That is, the flag is cleared so that additional registration after the -degree subtotal key 20 is input is normally processed by the next subtotal key 20 input.

It is checked whether the product code entered in step 118 exists in the single item table 24, and if there is no corresponding product or the number has not been entered, step 129 is performed.
Perform error handling. If there is a product, step 119
The quantity is added to the quantity area 244 of the single item table 24. Next, in step 120, it is determined whether the sequential discount flag 30 is set, and if it is set, it means that an instruction for preferential discount registration has been given before registration begins, so in step 122, the registration amount and discount of the corresponding department are determined. The amount after discounting is calculated from the rate, and the process proceeds to step 124.

If the sequential discount flag 30 is not set, the unit table 25 is referred to in step 121, and the department registration flag 257 of the department corresponding to the input department key is set to 1. Subsequently, in step 123, which is a product total storage means, the registered amount is added to the per-customer department sales area 256 of the corresponding department, and in step 124, the registered amount is added to the per-customer registered amount area 26. At step 125, the quantity is added to the quantity area 253 of the department table 25, at step 126 the registered amount is displayed, at step 128 the amount, etc. is printed by the R/J printer, and the process ends.

FIG. 7 is a flowchart of the subtotal processing at step 109 in FIG.

In step 130, it is determined whether the subtotal flag 32 is set. If it is set, the subtotal processing has already been executed, and the process proceeds to step 138. If the subtotal flag 32 is not set, the subtotal flag 3 is set in step 131.
2, and in step 132, set the [batch harm] pull flag 31.
It is determined whether the bulk discount flag 31 is set, and if the bulk discount flag 31 is not set, the process proceeds to step 138. If the bulk discount flag 31 is set, the department registration flag area 257 of the first department is checked in step 133 to execute the bulk discount process. This checks whether registration has been made for that department. If 1 is not set in the department registration flag area 257, there is no need to perform discount processing, and the process proceeds to step 136. If 1 is set in the department registration flag area 257, the post-discount amount a is calculated from the per-customer department sales and the discount rate in step 134, and the per-customer registration amount area 26 is cleared and added in step 135. This clearing is done only once at the beginning, and thereafter the addition process is simply repeated. In step 136, the processed counter 27 is incremented by 1, and in step 137, the number of departments preset in the number of departments area 28 is compared with the processed counter 27 to determine whether the discount processing has been completed for all departments. , if not completed, the address is updated to the next department, and the process returns to step 133 to repeat the discount process.

Steps 132 to 137 are calculation means. If the processed counter 27 and the number of departments match, it is determined that the process is finished, and in step 138 the contents of the per-customer registration amount area 26 are displayed, and the process is finished.

Next, the operation of this embodiment will be explained. Now product code 001
Let us take as an example a case where products 002 and 003 are registered and it becomes necessary to register them for a discount during the process. First, enter 001 and enter the food key, which is one of the department keys 18. As a result, 1 is added to the quantity area 244 corresponding to the code 001 of the single item table 24. Next, add 1 to the quantity area 253 corresponding to the food item in the department table 25, add 100 to the single customer department sales area 256, set 1 to the department registration flag area 257, and register the amount of 10.
Display 0. When the clothing key, which is one of the department keys 18, is input by setting the number 002, 1 is added to the quantity area 244 corresponding to the code 002 of the item table 24. Next, quantity area 2 corresponding to clothing in department table 25
Add 1 to 53 and add 500 to single customer department sales area 256.
is added, 1 is set in the department registration flag area 257, and the registered amount 500 is displayed. If the customer informs him that he is a preferential customer, he manually presses the preferential key 19. When the preferential treatment key 190 is input, the bulk discount flag 31 is set to 1 since registration has already been performed. Next, when the number 003 is entered and the book key, which is one of the department keys 18, is input, 1 is added to the quantity area 244 corresponding to the code 003 of the item table 24. Next, 1 is placed in the quantity area 253 corresponding to the book in the department table 25.
, 1000 is added to the customer department sales area 256, 1 is written to the department registration flag area 257, and the registration fee m1ooo is displayed. When the subtotal key 20 is input here, since the bulk discount flag 31 is set to 1, the amount after discount is calculated for each registered department. In other words, the food sector is l OO-100xO
,05 is 95, and the clothing department is 500-500X0
．． 1 will be 450, and the book category will be 1000-100.
0xO,01 becomes 990. The total of these is 153
5 is set in the per customer registration amount area 26, and this 1535
is displayed on the display 5. At this time, the data in the customer department sales area 256 of the department table 25 does not change in preparation for the additional registration. If there is any additional registration, the registration process will be re-executed after this. Assuming that the customer has deposited 1,535 yen, enter the number 1,535 and press the closing key 21.

As a result, change 0 is displayed and the deposit etc. are printed.

Then, data 100.
500.1000 are added respectively, and the per-customer department sales area 256, the department registration flag area 257, and the per-customer registration amount 2.
6. Clear the processed counter 27, registration flag 29, sequential discount flag 30, bulk discount flag 31, subtotal discount flag 32, etc., and end the registration process for one customer.

Further, if the customer informs the customer in advance that he/she is a preferential customer, the preferential treatment key 19 is inputted before registration. As a result, the discount flag 30 is sequentially set, and for the registration of this customer, the discounted amount with reference to the discount rate in the department table 25 is stored in the per-customer registration amount area 26 when the department key is operated. In this case, since the discounted amount is displayed one by one on the display 5, the customer can recognize that the discount has been registered.

In this way, according to this embodiment, when processing a discount for a preferential customer, etc., it is possible to specify the discount at the beginning or during the process, making the cashier's registration operation extremely easy. .

In the above embodiment, a discount rate is provided for each department, but it may be provided for each product. Furthermore, although a discount rate is provided, it is also possible to provide a discount amount or a unit price after discount. Furthermore, it only prints the amount after the discount, but
The discounted amount may also be printed at the same time. In this case, a storage unit is provided to store the discounted amount, and when calculating the sales for each customer department, the discounted amount is stored in this storage unit in total, and it is printed out together with the registered amount at the time of closing. good. In addition, various modifications can be made without departing from the gist of the present invention.

〔Effect of the invention〕

As explained above, the amount of the registered product is memorized and the discounted amount is calculated in the subtotal according to the bulk discount instruction, so the discount processing instruction for preferential customers etc. can be issued at any time. It can be done with As a result, even if a customer announces that they are a preferential customer during registration, the cashier does not have to perform cumbersome key operations, improving operational efficiency.
