Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic register having a time period aggregation function for managing sales data by time period by accumulating sales data by time period.

[Summary of the invention]

The present invention uses an electronic register that has a time-based aggregation function to store sales data of various product categories input during one transaction and total sales data input at the end of one transaction as if they were all input at the same time. By performing aggregation processing by time period, we ensured that the cumulative total of sales data in various categories for each time period always matches the cumulative total of sales data for each transaction unit for each time period. It is something.

[Conventional technology]

Conventionally, electronic registers have a time-zone aggregation function that allows management to be performed by time zone by summing up sales data sold during one transaction and aggregating the sales data by time zone as total sales data. (Japanese Unexamined Patent Publication No. 55-3017).

If you want to perform this management by time period more strictly, you will not only need to accumulate the total sales data for one transaction by time period, but also collect the sales data for each product category during one transaction by the time period. It is conceivable to classify and accumulate the data and perform more detailed management by time period.

[Problem that the invention seeks to solve]

However, as in the past, when the corresponding key (trading key in the past) was operated, the current time was read out and sales data (or total sales data) was accumulated in the storage area for the time period corresponding to that time. However, there are inconveniences in the following cases. In other words, the time for one transaction for one customer (i.e., the time from the time when the first classification key is operated after the transaction key is operated until the next transaction key is operated) spans two time periods. In this case, the time period in which the total is accumulated for each category by operating the first classification key is different from the time period in which the total sales data for one transaction is accumulated by operating the last transaction key. Therefore, the total sales data when the sales data corresponding to a certain time period are summed over all categories in a category totalizer that accumulates individual sales data by category and also by time period is There is a possibility that the total data does not match the sales total data for the specific time period of the transaction totalizer that accumulates the total data.

In this way, if the data obtained by summing all the sales data of each category totalizer in a certain time period does not match the sales total data of the transaction totalizer, when checking the time period aggregation status at the time of inspection or settlement, There is a risk of confusion, and accurate time management is not possible.

This invention was made based on the above-mentioned circumstances, and it is possible to perform accurate time-slot management not only when the transaction totalizer is used to aggregate by time period, but also when the totalizer for each category is aggregated by time period. The purpose of the present invention is to provide an electronic register with a time-slot aggregation function.

[Means for solving problems]

In order to achieve the above-mentioned object, the electronic cash register of the present invention includes: a classification designation means (department key) for designating the product classification of a product; a transaction designation means (cash key) for designating the end of one transaction; a first time period storage means (department memory) provided corresponding to each classification and having a plurality of time period storage areas for each classification; A second time zone storage means (cash transaction memory) having a time zone storage area divided into the same time zones as the time zone storage means in the first time zone storage means; Time zone data storage means (n register) for storing data indicating a time zone including the designated time when the first classification designation is made; and classification designation by the classification designation means when inputting sales data. is performed, the sales data is accumulated in the storage area of the time period determined by the data stored in the time period data storage means in the first time period storage means corresponding to the specified classification. When the termination of a transaction is specified by the cumulative totaling means (CPU...step _S11 ) of 1 and the transaction specifying means, the total sales data obtained by summing the sales data input during one transaction is calculated in the second time period. A second accumulating means (CPU...
Step _S15 ).

[Effect]

To explain the operation of the present invention, in one transaction for selling multiple products, first,
When the first classification designation is made by the classification designation means when inputting the sales data of the first product, data indicating the time zone including the designated time is stored in the time zone data storage means, and the data indicating the time zone including the designated time is stored in the time zone data storage means. The first accumulating means starts operating, and the sales data is accumulated in the storage area of the time period determined by the data stored in the time period data storage means in the first storage means corresponding to the specified classification. Subsequently, each time a classification is specified after inputting sales data for the second and subsequent products, the operation of the first accumulating means is started, and as a result, each sales data input from the second onwards is It is assumed that the sales data of the first product is input within the same time period, and is accumulated in the first storage means corresponding to each designated category. When the input of product sales data for one transaction is completed in this manner, the transaction designation means specifies the end of the transaction. Then, the second accumulation means starts operating, and the total sales data, which is the sum of the sales data input during one transaction, is calculated based on the data stored in the time period data storage means in the second time period storage means. The total is accumulated in the storage means for the determined time period. In this way, all the various sales data and sales total data input during one transaction are considered to have been input within the same time period, and are accumulated in the first and second time period storage means. .

(2) Operation Next, the operation of this embodiment will be explained. First, after turning on the power switch of the electronic register, set the mode switch to "setting" mode, and operate the numeric keys and time keys in sequence to set the time of 9 o'clock to start counting by time zone. input. Then, the time is stored in the S register of the RAM 11. Next, when the mode switch is set to the "registration" mode, the operation according to the flow shown in FIG. 4 is constantly executed.

In other words, in the execution of step _S1 , the RAM
``60'' is added to the start time of the time period aggregation stored in the S register of RAM 11, and the end time of the first time period is calculated and written to the A register of RAM 11. Next, in execution of step _S2 , n register "0" of RAM 11 is written. Next, the process moves to step _S3 and waits until a key operation on the input section 1 is performed, and when it is determined that a key operation has been performed, the process moves to step _S4 . In step _S4 , a judgment is made as to whether or not the operated key is a departmental key, and if the answer is YES, the process moves to step _S5 . In step _S5 , a determination is made as to whether or not a flag "1" indicating a cash key operation is stored in the F register of the RAM 11. If YES is determined, the process moves to step _S6 . In executing step _S6 , "0" is written to the F register. Next, the process moves to step _S7 , where the current time data stored in the TM register of the clock circuit 7 is transferred to the RAM 11.
is transferred to the B register of Then step S ₈
Then, a judgment is made as to whether the current time data in the B register is greater than or equal to the end time data of one time period in the A register, and if it is judged as YES, the time period is considered to have already passed. Then move to step _S9 . In the execution of step _S9 , "60" is added to the time slot end time data in the A register, and the result of this addition is written into the A register as the end time data for the next time slot. Next, proceed to step S ₁₀ to update the RAM.
"1" is added to the contents of the n register of 11,
After this, return to step _S8 . If it is determined in step _S8 that the current time data in the B register is smaller than the time zone end time data in the A register, the process moves to step _S11 . Also, if it is determined in step _S5 that F≠1, the process moves to step _S11 . The sales data stored in the X register of the RAM 11 is stored in the storage area M(n) specified by the contents of the n register among the storage areas of the departmental memory corresponding to the departmental key operated in step _S11. is added. Next, the process moves to step _S12 , where the sales data of the register together with the department number of the operated department key are printed on the recording paper in the printing section 4, after which the process returns to step _S3 .

If it is determined in the step _S4 that the operation key of the input section 1 is not a departmental key, the step
Move on to _S13 . In step _S13 , it is determined whether the operation key is a cash key or not, and YES is determined.
If it is determined that this is the case, the process moves to step _S14 . step
At _S14 , "1" indicating a cash key operation is written in the F register of the RAM 11. Next, the process moves to step _S15 , in which storage means G of the memory for each cash transaction specified by the contents of the n register is stored.
Total sales data for one customer is added to (n). Next, the process moves to step _S16 , where the sales total data is added to the storage area of the total memory 6 for storing the total sales total. Then step
The process moves to step _S17 , and the printing unit 4 prints various information such as the sales total data, deposit amount, and change on the recording paper, and then returns to step _S8 . If it is determined in step _S13 that the operation key is not a cash key, the process moves to step _S18 . In step _S18 , other key processing is executed depending on the operated key, and then the process returns to step _S3 .

When the registration process for one customer is started and the department key is operated for the first time, "1" is written in the F register by the transaction key operation described above, so in the flow of FIG. S ₄ ~ _{S 8} , S ₁₁ , S ₁₂ , or step S ₄ ~
S ₁₀ , S ₈ , . . . are sequentially executed, and the sales data is added to the storage area M(n) of the departmental memory for the time period at which the departmental key is operated. When the department key is operated after this, steps S ₄ , S ₅ , S ₁₁ , and S ₁₂ are executed in sequence, and the sales data for each department is specified by the contents of the n register and stored in the storage area for the time period. Sales data is accumulated in M(n). Then, when the cash key is operated at the end of departmental registration of sales data, the total sales data is added to the storage area G(n) of the time period specified by the contents of the n register similar to the above. . Therefore, even if the start of registration for one customer by operating the departmental key and the end of registration by operating the cash key span two time periods, sales by department The data and total sales data for each transaction are accumulated in each storage area in the same time period, that is, at the time of the first operation of the department key.

In the above embodiment, a departmental memory is provided as the first time zone storage means, but the present invention is not limited to this.
It is also possible to provide PLU memories and perform time period aggregation in these PLU memories.

〔Effect of the invention〕

As explained above, according to the present invention, data indicating the time period when the classification designation by the classification designation means is determined to be the first designation in one transaction is stored, and the data designated by this data is stored. The sales data input by the classification designation means or the sales total data input by the transaction designation means are stored in the first or second time zone storage means respectively. Since the total sales data is accumulated, it is possible to manage not only the total sales data by time period, but also the sales data by various categories by time period. It is possible to always match the contents of the separately totaled time with the contents of the accumulated sales total data for each time period, and accurate management by time period can be performed.
