The RAM 10 is provided with an area f, which stores whether or not a "%" key is pressed at the beginning of a customer's registration operation until the customer's registration operation is completed.

FIG. 2 shows the configuration on the operation panel of the embodiment of the present invention.

Numerical keys 1, a group of function keys 3, a mode switch 5, and a paper feed instruction key 15 for the printing means 12 are provided.

Hereinafter, the operation of the embodiment of the present invention will be explained according to a flowchart.

(1) Setting of various data A flowchart is shown in Fig. 3. The operator first selects the mode switch 5 to the setting mode position to enter the setting mode, and temporarily stores the setting mode information in the buffer means 6 (s-31). Next, when the operator operates either the numeric key 1 or the function key group 3, the key force detection means 7 operates, and the setting mode information temporarily stored in the buffer means 6 is transferred to the area a of the CPU 9.
(S-32). When the setting mode information is stored in area a, the CPU 9 determines that the stored information is setting mode information, and selects and specifies the setting operation processing program previously stored in the ROM 8 (S-3
3).

(1a) Setting the discount rate Once the setting operation processing program has been selected in this way, the operator can then enter the predetermined code using numeric key 1 and then press the "#" key to start the discount rate setting processing program. Give a selection instruction to the CPU. Upon receiving this instruction, the CPU specifies the discount rate setting processing program from among the setting operation processing programs selected earlier (S3
4).

When this program is specified, the operator inputs the discount rate into the CPU 9 using the numerical keys 1 and the "%" key 17. Upon receiving this discount rate, the CP U9 designates Elina g in the RAM 10 to set and store the discount rate (S-35).

Further, the set discount rate is displayed on the display means 11 and simultaneously printed on the receipt or journal by the printing means 12. In this way, when the setting of the discount rate is completed, the operator presses the rTLJ key 18 and the CPU 9
The device is notified that the discount rate setting has been completed, and the device is put into a key standby state (s-36).

(Ib) Setting of PLU information First, the operator selects and instructs the PLU information setting processing program using numeric key 1 and "#" key 16 (S
-37). Upon receiving this instruction, the CPU 9 designates the PLO information setting processing program from among the previously selected setting operation processing programs.

Once this program is set, the operator inputs the PLU code into the CPU 9 using the numerical keys 1 and the PLU key 14. CPU9 that received this PLU code is RA
The area corresponding to the PLU code input to M10 is selected and designated (S-38).

Next, when the operator inputs the unit price information of the product corresponding to that PLU code using numerical keys 1 and ST primary key 5, that unit price information is set and stored in area d corresponding to the previously specified PLU code. At the same time, the printing means 1
2 and the display means 11 displays the printout 1 (S-39
).

The operator performs the above operations on all PLUs and sets the unit price information for each product. When all settings are completed, the operator operates the "TL" key and displays the PLU.
Complete your information setup tasks.

(2) Registration Process FIG. 4 shows a flowchart of a program related to registration processing.

Now, when a certain transaction registration process occurs, the operator sets the mode switch 5 to the registration mode, temporarily stores the registration mode information in the buffer means 6, and selects and specifies the registration process program stored in advance in the ROM 8. , the data that will be input thereafter will be processed according to this program.

Specifically, when discounting all or most of the registered products, the operator first presses the "%" key 17 (S-40) and sets a flag in area f of the RAM 10. (S-41).

This "%" key 17 is a key operated at the beginning of the registration process for one customer, and the flag in area f is the second storage means for storing this operation.

Next, the operator determines whether the registered product is a product that can be registered as a PLU (S-42), and if PLU registration is possible, enter the corresponding PLU code using the numeric key 1 and the PLU key 14. Input to CPU9. This PLU
When the code is input to the CPU, the CPU specifies the corresponding PLU code area in area d of RAMl0, and
The unit price information stored in is read out (S-43), and print 1 is displayed by the printing means 12 and display means 11.

Next, the CPU 9 determines whether or not a discount instruction flag is set in area f, and if the flag is set, the CPU reads out the discount rate previously set in area g.S-44 ), performs a discount calculation with the previously input product unit price information (S-45), displays the result in print 2 on the printing means 12 and the display means 11, and
This is stored in a predetermined storage area of the RAM 10 (S-
46).

Furthermore, if the registered product is a product that cannot be registered in PLU, the operator inputs the unit price of the product using numeric key 1, uses the predetermined department key, and calculates the discount for the registered product in the same way as described above. (S-47).

On the other hand, if the flag is not set in area f, when discounting a registered product registered in PLU or department, use the 1% key to calculate the discount using the discount rate stored in area g. Alternatively, the discount calculation is performed using the discount rate input using the numeric key 1. If discount processing is not to be performed, product registration is completed as is.

When the registration of all trading products is completed as described above, the operator presses the registration completion instruction key "TL" and presses the C
The PU 9 is instructed to end the registration processing operation (S-48).

Upon receiving this instruction, the CPU 9 calculates the total transaction amount of the registered data, adds the total amount to the area t of the RAM 10, prints it on the receipt journal using the printing means 12, and simultaneously displays it on the display means 11.
49). The operator sees this display, receives payment for the transaction from the customer, inputs the deposit, calculates change, issues a receipt to the customer, and completes the transaction registration process. At this time, the CPU 9 cancels the flag of area f in the RAM 10 (S-50).

It goes without saying that if the flag in area f can be cleared by operating the ST key (subtotal), the functions of the present invention can be effectively utilized during -transactions.
