Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a sales data processing device such as an electronic register.

[Prior art and its problems]

Conventionally, in electronic registers, the unit price is set in advance in the total memory corresponding to PLU data (data by product classification), and each time sales data is input at the time of PLU registration, that sales data is stored in the total memory. The total sales data by PIU will be accumulated. A PLU like this
For electronic registers that allow registration, if there are many products such as a large store, the P.P.
As a result, there were drawbacks such as the PLU number search process executed at the time of PLtlIi taking a long time.

[Purpose of the invention]

This invention was made against the background of the above-mentioned circumstances, and its purpose is, for example, to avoid the need for a huge amount of memory even when there are many products to be handled when performing FLU registration, and to save memory. It is an object of the present invention to provide a sales data processing device that can effectively utilize PLURfi and the like.

[Key points of the invention]

In order to achieve the above-mentioned object, this invention stores the total sales data for each type together with the role data such as the type and unit price, erases the total sales data for each type at the time of payment, and The gist is that the setting data of the specified type is deleted.

[Configuration of Example]

Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings. FIG. 1 is a system configuration diagram of an electronic register to which the present invention is applied. On the keyboard of the input unit 1, there are number keys IASFLU key IB1 cash/deposit key 10. A clear key 1D1, a preset key IN, a conversion key IF, and a mode switch IG1 lamp IH are provided.

Mode switch IG is "Settings", "Registration", "Electronic 1li"
2OFF", "Inspection", and "Payment-" modes. Thus, key operation signals and mode switches are outputted from the input unit 1 corresponding to the operation keys! The mode designation signal output corresponding to each switching position in () is CjPU
C central processing circuit) 2.

C! PU2 executes various operations, such as manual processing, registration processing, display processing, etc., according to pre-stored microinstructions, and controls various registers, A-F and C.
In addition to the register, there is also a control unit CT.

It has a configuration including an arithmetic unit ALt-. However, 0
The PU2 exchanges data with the RAM (Random Access Memory) 3 and accumulates the total sales data for each PLU in the RAM3.
It reads out program data from the computer and executes operations according to the program, opens the drawer 5, and supplies sales data and the like to the display section 6 and printing section 7.

ILAM3 stores total sales data for each PLU, and memory M1 stores the PLU number, Mt stores the unit price, M,
The number of sold items is stored in , and the setting control flag is stored in M.

Here, the setting control flag stored in the memory M4 determines whether the FLU number and unit price data preset in the corresponding memories M, M, are to be deleted at the time of checkout according to the total number of sales stored in the memory Ms. This is used to store the flag indicating.

[Operation of the embodiment]

First, before executing PLU registration, the memory M of RAM3,
The FLU number and unit price are set in advance for ,M. In this case, the mode switch IG is switched to the "setting" position to enter the setting mode. In this setting mode, the 21st iJ
It is assumed that the PLU number and unit price are input according to the key operation procedure shown in (A). That is, for example, after setting the FLU number "1", the PLU key is operated, then after setting the unit price "30", the preset key is operated. Then, the operation according to the flow shown in FIG. 2(B) starts to be executed. First, in step T+, RAM3
The memory M of is searched and the PLU number placed in the A register is written into the empty area. Next, FLU
Memory M corresponding to the address address of memory M1 where the number is set! The unit price placed in the B register is written into the address of 6. When the FLU number and unit price are input in this way, the FLU numbers from "1" to "n" are sequentially set in area M1 of RAM3, and the FLU numbers from "1" to "n" are sequentially set in area M, corresponding to the PLU number. Unit price is set.

When the setting of the FLU number and unit price is completed in this manner, the setting control flag set in the memo IJM of the RAM 3 is changed while remaining in the setting mode. This changing operation is performed according to the operating procedure shown in FIG. 3(A). That is, for example, after setting the PLU number "1", the FLU
Operate the key, then operate the change key. Then, the third
The operation according to 70- in Figure CB) is started.

First, in step 'I'l+, the input FLU number is retrieved from the memory M. As a result, the setting control flag stored in the memory M corresponding to the retrieved FLU number is read out and transferred to the C register (step T!+t). Then, it is determined whether the setting control flag thus transferred to the C register is "l" (step T15), and as a result, if it is "0", it is "1", and if it is "l", it is "1". The setting control flag is inverted to "0" (step T, step T+s). In this way, each P
The setting control flag corresponding to the LU number can be changed as desired, but in this case, the setting control flag corresponding to the FLU number with high sales according to the past sales situation is "1", and the setting control flag corresponding to the FLU number with low sales is "1". The setting control flag corresponding to the number is set to "0".

Next, when executing FLU registration, first, the mode switch IG is switched to the "registration" position to enter the registration mode. In this registration mode, when registering sales data for each product, as shown in FIG. 4(A), enter the FLU number and then operate the PLU key. As a result, the operation according to 70- in FIG. 4(B) is executed.

First, in step TxI, the input PLU number is searched from the memo IJM, and as a result, the input PLU number
It is determined whether the U number has been stored in the memo IJMI (step T0). If there is a FLU number input into the memory MI, the process jumps to step Tt6 and it is determined whether there is data in the B register.

In this case, as will be described in detail later, in the above case, the mode switch IG is first switched to the "registration" position to enter the registration mode. In this registration mode, the FLU registration operation is as shown in Fig. 4 (A).
After setting the FLU number as shown in
- Operate. As a result, the operation according to 70- in FIG. 4(B) is executed. First, in step Ttl, the input PLU number is stored in the memory M.

The search process is then executed. As a result, the input PLU number is searched from memory M+ and the PLU number is searched from memory M+.
It is determined whether the U number has been set in memory M (step Tron). If it is not present in memory M, an empty area of memory M1 is searched and A is set in that empty area.
The input PLU number stored in the register is newly set (step Ttm). Then, to indicate that a new PLU number has been set, a new setting flag is set in the F register (step T!4), and then the lamp IH on the keyboard is lit to notify the operator of this fact. will be notified. Therefore, in the next step T, it is determined whether there is data in the B register. In this case, create a new FLU as described above.
When a number is set, the operator can confirm this status by lighting the lamp, and from this, the unit price corresponding to that FLU number can be entered manually or the unit price at this time will be entered in the B register. Become. Therefore, in the present case, the unit price has not been input, and as a result, there is no data in the B register, so proceeding to step Tty, it is determined whether the new setting flag is set in the F register. Since it has been set in the present case, the operation associated with the PLU registration process ends at this point.

However, when the lamp lights up, the operator
) Newly set P according to the key operation procedure shown in
After entering the unit price “30” that corresponds to the LU number,
Operate the preset keys.

As a result, execution of the 41st iU(B) flow is started again, but in this case, since the PLU number has been newly set in the memory M1, the process advances to step T16. In this case, since the unit price is set in the B register, the process advances to the next step Tza and the newly set FL
7lag@1” is set in the memo IJM corresponding to the U number.Then, the unit price set in the B register is set in the memo IJM corresponding to the newly set FLU number.
M! (step 'I'ts). However,
Normal PLU registration (steps Ts to Tst) is performed. That is, the number of sold units is read from the memory M corresponding to the newly set FLU number, transferred to the C register, and then an increment process is performed to increase the value of the C register by 1. The contents of the 0 register are loaded into the memory Ms k-1f. As a result, the number of sales of memory M is updated.

When such registration processing is completed, the B and F registers are each cleared (step Tag).

In addition, the above step T! ! If the FLU number input in step Ttl is already set in memory M, the process advances from step Ttl to step T, and then to step T, 7.
Steps T H - T ss are sequentially executed from then on.

In this way, in FLU registration, if the input PLU number is not set in the memo UM, this FLU
The unit price is newly set together with the number, and thereafter, the registration process corresponding to the newly set PLU number is executed.

If you want to perform the next inspection, switch the mode switch IGt to the "inspection" position to set the inspection mode, and then operate the cash/deposit key to execute the operation according to step 5@. Ru. That is, first, in step T41, an inspection mode flag is set in the r register. Then, the initial value "1" is set in the a register, which functions as an address counter (at step T4, successive addresses of memories M, , M, , M, are specified by the contents of the a register, and this causes the reading The issued PLU number, unit price, and number of pieces are transferred to the corresponding A, B, and O registers (step T4J).The unit price set in the B register is then multiplied by the number of pieces in the C register to obtain the sales amount. The sales amount is calculated and transferred to the D register (step T4.).

Subsequently, the memo I addressed by the contents of the a register
After the setting control flag is read from JM and transferred to the E register, it is determined whether the flag is "1" (step T41% T46).

As a result, if the setting control flag is 101, AlB, O
, -D register contents are printed and displayed (step T41), and if it is "1", ASB.

In addition to the contents of the Q and D registers, an identification symbol Δ indicating this
is printed and displayed (step T4.).

However, in the inspection mode, the F register has 1"
is set, this is detected in step T4, and the process jumps to step Tss, where the value of the turtle register is incremented by 1, and as a result, the value of the & register becomes the final address.
If it is not the final address, the process returns to step T41 and the above-described process is repeated, so that the inspection process is executed for each PLU number. When all inspection processing is completed, the contents of the F and & registers are cleared (□ in step).

Next time you want to pay the bill, set the mode switch IG to the "Payment" position and set it to the "Payment" position.
When the deposit key is operated, the flow shown in FIG. 5 starts to be executed. First, as in the case of the above-mentioned inspection, step T4! ~T4. is executed and a settlement report is created, but at the time of settlement, the content of the r register is O'', so
Proceeding to the next step TH, it is determined whether the setting control flag in the E register is 1'', and if it is 1'', the memories M+, Mu, Ms, M specified by the contents of the a register are
4 are cleared respectively, but if ``0'', memory M1
only is cleared (step TII%Tsy). That is, at the time of normal payment, only the number of sold items in the memory Ml is erased, but especially when the setting control flag is set to "1", setting data such as the PLU number and unit price are also erased in addition to the number of sold items. It will be deleted including. When this rear processing is completed, the value of the a register is incremented by 1, and step T4 is performed until the value becomes In''.
, and the above-mentioned payment processing is executed corresponding to each FLU number.

In this way, in this embodiment, in addition to the number of sales, the FLU number and unit price are also deleted when calculating M according to the ° setting control flag set in advance for each FLU number. If you do not need to set the FLU number or unit price for a product that is underperforming, for example, a product that has no sales at all, you can set the corresponding setting control 7 to 11#, and those setting data will be saved at the time of checkout. will be deleted and become an empty area, so RA
You will be able to use M3 effectively.

In addition, in this embodiment, in addition to the sales data at the time of checkout, setting data such as the FLU number and unit price are also deleted according to the setting control flag set in advance for each PLU number. It may be determined whether the sales data is less than a predetermined value, and the setting data may be deleted according to the determination result. Further, the setting data may be deleted only when the setting data is newly set in the registration mode. Also, the RAM memory area is 2
It is also possible to store data on products with high sales in one memory area and data on products with low sales in the other memory area, and erase all of the other memory area at the time of checkout. In addition, various modifications and applications may be made without departing from the scope of the present invention.

〔Effect of the invention〕

As explained in detail above, this invention stores total sales data for each type together with setting data such as the type and unit price, erases the total sales data for each type at the time of payment, and stores the total sales data for each type in advance. Since the setting data of the selected type is also deleted, the memory capacity can be used effectively.
