Description

[Detailed description of the invention] [Industrial application field] This invention relates to a sales data processing device such as an ECR (electronic cash register).

[Prior Art] Conventionally, in ECR, registration is performed based on the unit price inputted together with the designation of PLU (Brice Luk Up), department, etc. Furthermore, in order to prevent the input of a unit price that does not exist during registration, the lower limit value is stored in memory and the input unit price is checked. For example, the one shown in Japanese Unexamined Patent Publication No. 57-132266 is known.

[Problem that the invention aims to solve] By the way, even when setting unit prices other than when registering, it is desirable to prevent the input of impossible unit prices, but the conventional lower limit value does not cover all of the determined unit prices. Since the operator sees and inputs the unit price, it is not possible to check the set unit price using the conventional lower limit value, and there is a risk of inputting the set unit price incorrectly.

By the way, in ECR, in addition to storing the unit price, etc., it also stores the cost price, and the unit price is set by subtracting the cost price only in special cases (such as a bargain sale).

Therefore, if the unit price to be set is checked using the cost price, erroneous unit price settings can be prevented without requiring a special memory for checking.

However, in cases such as low-price sales, the unit price may be set by subtracting the cost price, so if a unit price that is subtracting the cost price is checked during the check, it may be locked (setting prohibited). It is necessary to remove the setting prohibition for those that have been set to . In other words, if the device is locked, normally the process is terminated once, and in order to continue the process, the process must be restarted from the beginning.In order to eliminate this troublesome restart specification, the setting is disabled. It is desirable to release only that.

The problem of this invention is to make it possible to check whether an incorrect unit price has been input when setting the unit price, and to make it possible to cancel the prohibited state as necessary if the setting is prohibited due to this check.

[Means to solve the problem] The means of this invention are as follows.

Unit price storage means (memory _M2, etc.) that stores the unit price of the product set by the unit price setting means; Cost storage means (memory _M4, etc.) that stores the cost of the product set by the cost setting means. In a sales data processing device equipped with calculation means (CPU 3 and steps Q ₇ , Q ₈ etc. processed by CPU 3) that calculate profit amount using the cost price in the cost storage means, a new unit price is set in the unit price storage means. setting control means (CPU 3 and steps P ₄ and P ₅ processed by CPU 3, etc.) that prohibits unit price setting when it is determined that the new unit price is less than the cost in the cost storage means; The apparatus includes a release means (CPU 3, key 2B, etc.) for releasing the prohibition state of unit price setting by the setting control means.

Note that the words in brackets are added for reference in order to clarify how the above-mentioned means are embodied in the embodiments.

[Effect] The function of this device is as follows.

The unit price of the product set by the unit price setting means is stored in the unit price storage means, the cost of the product set by the cost setting means is stored in the cost storage means, and the profit amount is calculated using the cost price. In the sales data processing device that calculates by the calculation means, when setting a new unit price in the unit price storage means, the setting control means stores the new unit price and
The cost price in the cost storage means is compared, and if the new unit price is less than the cost price, unit price setting is prohibited, but if the unit price is set below the cost price due to bargain sales, etc., the release control means is used. The prohibited state is released.

Therefore, when setting a unit price, it is possible to check whether an incorrect unit price has been input, and if the setting is prohibited as a result of the check, the prohibited state can be canceled as necessary.

[Example] An example will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a system diagram of a sales data processing device. Through the bus line 1, there is an input section 2, a CPU (central processing unit) 3 that performs various processing according to various microprograms stored in advance, a memory 4, a display section 5, a printing section 6, and a drawer 7. is connected.

2A of the input section 2 is a numerical input key, 2B is a key for inputting a bargain unit price in the unit price setting mode,
2C is a key that prohibits the unit price setting mode, 2D is a lamp that indicates a unit price setting error when the unit price is input lower than the cost price in the unit price setting mode, 2E is the cash/deposit key, 2F is the clear key, 2G is the PLU key, 2H is a mode switch.

In addition to the control section 3A and the calculation section 3B, the CPU 3 includes:
It consists of registers A to F and f. The A register is set to PLU No., the B register is set to the unit price, the C register is set to the cost or profit amount, the D register is set to the quantity, and the E register is set to the cumulative profit amount. is,
The F register is used as an address counter,
A unit price setting flag is set in the f register.

The memory 4 consists of a memory M ₁ that stores PLU No. 1 to n, and memories M ₂ , M ₃ , and M ₄ that store the corresponding unit price, number, and cost.

Next, the operation of setting the cost price will be explained.

First, the mode switch 2H is set to cost setting mode. Then, input the PLU No. of the product from the key 2A of the input section 2, then operate the PLU key 2G,
Next, input the cost price using key 2A, and then operate the cash/deposit key. Then each of these key outputs are
The data is input to the CPU 3, and the flowchart shown in FIG. 2 is executed.

That is, the F register is incremented by 1 and the address counter is incremented by 1 (step S ₁ ), and then that count value is set in the A register.
It is determined whether or not it matches PLUNo. (step _S2 ). And if they don't match, step until they match.
S ₁ and S ₂ are repeated; on the other hand, if they match, step S ₃
Then, the set cost set in the C register is transferred to the PLU No. area of the memory _M4 in the memory 4. The A, C, and F registers are then cleared (step _S4 ), and the process ends.

When inputting a new unit price for a pair, set mode switch 2H to unit price setting mode, and press key 2 of input section 2.
Enter PLU No. from A, then operate PLU key 2G, then enter the unit price from key 2A, and then press the current/
Operate deposit key 2E. Then, the flow in the center of FIG. 3 is executed by the CPU 3.

That is, first, PLU No. is determined by steps P ₁ and P ₂ .
is searched and once searched its memory M ₄
The cost price of PLU No. is transferred to the C register (step _P3 ). Next, it is determined whether B≦C between the set unit price set in the B register and the above cost price, that is, whether there is a setting error or not (step
_P4 ). If B≦C, that is, the set unit price≦cost, it is an error, so the lamp 2D is lit for a certain period of time (step _P7 ), and the unit price setting flag "1" is set in the f register.

On the other hand, if the set unit price is larger than the cost price, it is a normal input, so that unit price is transferred to the PLU No. area of memory _M2 (step _P5 ), and A, B, C,
The F and f registers are cleared and the process ends (step _P6 ).

On the other hand, in the case of a bargain sale, the key 2B is operated, and in this case, the left branch of the flow in FIG. 3 starts and it is determined whether the f register is "1" (step _P9 ). If it is "1", it is in the unit price setting mode, so the low price unit price set in the B register is stored in memory _M2 .
Transfer to the area of PLU No. (step _P5 ), then perform step _P6 and end.

On the other hand, if the flag is not "1", the current unit price setting mode is not in effect, so this flow ends and the current key operation becomes invalid.

Further, when unit price setting is prohibited, if the key 2C is operated, the process advances to step _P10 of the right branch, and it is determined whether the flag in the f register is "1". If it is "1", proceed to step _P6 and invalidate the current unit price setting; on the other hand, if it is not "1", it is irrelevant and the process ends.

Next, when the cash/deposit key 2E is operated in the payment mode, the flowchart shown in FIG. 4 is started, and first, in step _Q1 , normal payment is performed using products for each PLU No.

Next, in step _Q2, the F register is incremented, and the unit price of the memory _M2 of that PLU No. is read out to the B register (step _Q3 ). memory in pairs
The cost price of that PLU No. of _M4 is read into the C register (step Q ₄ ), and then in step Q ₅ the cost price is subtracted from the unit price and the profit margin is set in the C register.

Next, the number of PLU No. in memory M ₃ is read to the D register (step Q ₆ ), and then the profit margin is multiplied by the above number to calculate the profit amount, which is set in the C register (step Q ₇ ). ). Next, this profit amount and the cumulative profit amount in the E register are added to calculate a new cumulative profit amount and set in the E register (step Q ₈ ).

Next, it is determined whether PLUNo. of the F register is the final n (step _Q9 ), and if NO, the step
Returning to Q ₂ , on the other hand, if YES, proceed to step Q ₁₀ , where the gross profit amount of the E register is displayed and printed in the display section 5 and printing section 6 (step Q ₁₀ ),
Next, in step _Q11 , the B, C, D, E, and F registers are cleared, and the process ends.

Note that although the above embodiment uses PLU, the cost price set for each department may be used. Further, the lamp 2D may be replaced with a sounding body such as a buzzer.

[Effects of the invention] According to this invention, it is possible to check whether an incorrect unit price has been input when setting a unit price, and if the setting is prohibited by checking, the prohibited state can be canceled as necessary. Therefore, the setting process can be easily continued without rebooting as usual, and erroneous input can be eliminated. In addition, since it is a sales data processing device that checks the set unit price by using the cost price set in the department or PLU as the minimum amount in order to calculate the amount of profit, it is compared to a device that stores check data separately. This eliminates the need for extra memory capacity, operations, processing, etc., making the configuration simple and cost-effective.
