Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is a POS (point-of-sale information management) that is centrally managed by an electronic cash register or a host controller.
The present invention relates to a product sales data processing device such as a terminal, and more particularly, to improvement of a device that can automatically calculate privilege points commensurate with the total price of products purchased by customers.

[Prior Art] Some retail stores, such as supermarkets and specialty stores,
Accumulate bonus points calculated based on the sales price of the product purchased by the customer in the memory card issued to the customer, and provide services such as gift certificates and gifts based on the accumulated point value stored in the memory card. In this way, some stores are operating with the aim of retaining customers.

As a product sales data processing device such as a POS terminal used in such a store, when the closing operation of product registration for one customer is performed, the total amount of the customer is divided by a preset point reference amount. Points are calculated by calculating the bonus points by multiplying the calculated points by a fixed point multiplication factor, and the bonus points are cumulatively recorded in the memory card of the customer installed in the card reader / writer. Things are known.

Here, the point reference amount and the multiplying factor are set in advance in the internal memory, and the setting contents are changed by a complicated key operation of the keyboard in a state where the setting mode is selected. Therefore, if the point magnification is changed during the registration work, the registration work is temporarily interrupted, which may annoy customers when the store is crowded. Therefore, it was extremely difficult to change the point multiplication factor during the registration work.

[Problems to be Solved by the Invention] As described above, in the conventional product sales data processing device capable of automatically calculating the privilege points commensurate with the total amount of customers, it is extremely difficult to change the point multiplication factor during the registration work. Therefore, for example, it was not possible to carry out a store operation in which the point multiplication factor is increased only in an arbitrary time zone of the day to give a greater privilege to a customer who shopped during the time zone.

Therefore, the present invention is capable of automatically calculating privilege points commensurate with the total amount of customers, and it is possible to change the point multiplying factor in a specific time zone without hindering registration work, and store operation using privilege points The present invention aims to provide a product sales data processing device that can be expanded.

[Means for Solving the Problem] A product sales data processing device according to the present invention comprises a time measuring means for measuring a current time, a time zone setting means for setting a time zone,
When the registration operation is performed, the point calculation means for calculating the points for the total amount of the products sold to one customer based on the preset point reference value and the time measurement means when the registration operation is performed Based on the comparison means for comparing the current time with the time zone set by the setting means, and based on the comparison result by this comparison means, for example, when it is determined that the current time is outside the set time zone, the point calculation means is used. It is provided with a point output control means for outputting the calculated points as they are and for multiplying the points calculated by the point calculation means by a predetermined magnification when it is determined that the time is within the set time zone.

[Operation] With the product sales data processing device of the present invention thus configured, when the registration of the product sold to one customer is completed and the registration closing operation is performed, the point reference value set in advance is set. Based on this, points for the total amount of money of the customer are calculated. If the current time measured by the time measuring means is outside the time zone set by the setting means, the calculated points are output as they are. On the other hand, if the current time is within the set time period, the calculated points are multiplied by a predetermined scaling factor and output.

[Embodiment] An embodiment in which the present invention is applied to an electronic cash register will be described below. In this example,
A case will be described in which the privilege points for the total amount of money of the customer are accumulated in the privilege card including the magnetic card issued to the customer. In this case, on the magnetic recording surface of the privilege card, a storage area for privilege points is provided in addition to a customer code and a shop code for identifying the customer.

A selection designation signal from the mode switch 24 for selectively designating various business modes such as “registration”, “payment”, “inspection”, and “setting” is input to the. From the I / O port 20, a printer drive circuit 26 of a printer 25 for printing receipts and journals, and a drawer opening device for opening a drawer 27.
The drive signals from the CPU 11 are output to 28 and 28, respectively.

In addition, as shown in FIG.
Numeric keys 31 for entering numerical data, multiple department keys 3 preset with department codes for classifying each product
2, subtotal key 33, deposit / cash total key 34 for commanding closing of product registration due to cash transactions, multiplication key for entering multiplier
35, various function keys such as special treatment key 36 for entering the special treatment level of special treatment customers are provided.

On the other hand, in the RAM 14, as shown in FIG. 1, the department totalizer 41 for cumulatively registering the sales number and sales amount of each product by department code, the point memory 42 for storing privilege points, and the sale to one customer Total amount memory 4 for cumulatively storing the sales amount of the sold products, reference amount memory 44 for setting and storing a fixed point reference amount used for point calculation,
In addition to the flag memory 45 of the card flag CF that is set (1) when the privilege card is attached to the card reader / writer 24, a department point calculation table 46 including a department area, a multiplying area, and a total amount area, a special treatment A preferential treatment ratio table 47 composed of a level area, a magnification ratio area and a preferential treatment flag area, a time period magnification table 48 composed of a time zone flag area, a start time area, an end time area, a magnification area and a realized amount area are formed.

Here, the departmental totalizer 41 is provided with a specific department flag F1 for distinguishing whether or not the department is a specific department for which a magnification different from the normal point magnification is set. In the department point calculation table 46, the normal point multiplication factor for departments other than the specific department (specific department flag F1 = 0) is set corresponding to the department code “00”, and the specific department (F1 The point multiplication factor for = 1) is set corresponding to each department code. In addition, the point multiplier is set in the preferential treatment ratio table 47 in correspondence with the preset preferential treatment level of the customer, and the point multiplier at the preferential treatment level in which the preferential treatment flag is set to "1" is effective.

Further, in the time period multiplication table 48, the point multiplication factor and the established amount are set corresponding to a preset time period (start time to end time) (time period setting means), and the time period flag is "1". The point multiplication factor and the established amount for the time zone set in are valid. It should be noted that the time zones do not overlap within 24 hours and may be set over one day.

When the power is turned on, the CPU 11 checks the state of the mode switch 24 via the I / O port 19. Then, when it is judged that the "setting" mode is selected and designated by the mode switch 24, the key input from the keyboard 22 is waited for, and the specific department flag F1 of the department totalizer 41 in the RAM 14 in the RAM 14 is set as a reference. Amount memory 44
Point standard amount of money, department code and point multiplier of department-specific point calculation table 46, point multiplier of preferential treatment ratio table 47, time zone of table 48
The setting amount of money and the time zone flag are appropriately set.

On the other hand, when it is determined that the "register" mode is selected and instructed by the mode switch 24, the program is controlled to execute the process shown in the flowchart of FIG. That is, first, the keyboard circuit 17 is designated as ST (step) 1.
It is determined whether or not a key signal from the keyboard 22 is input to. If there is no key signal input, press ST
As 2, it is determined from the state of the card reader / writer control circuit 16 whether or not a privilege card for accumulating privilege points is attached to the card reader / writer 21. Here, when it is detected that the privilege card is attached to the card reader / writer 21, the state of the card flag CF of the flag memory 45 is checked in ST3. Then, the card flag CF is reset (0)
If so, the privilege card is just mounted on the card reader / writer 24. Therefore, after setting (1) the card flag CF, the card reader / writer control circuit 16 is controlled to read by the card reader / writer 21. Then, the card data of the privilege card is fetched, the privilege points in the card data are stored in the point memory 42, and this processing is ended.

On the other hand, the card flag CF is set in ST3 (1)
If so, the privilege card is still attached, and this process ends without doing anything.

On the other hand, when it is detected in ST2 that the magnetic card is not attached to the card reader / writer 21, the state of the card flag CF in the flag memory 45 is checked in ST4. If the card flag CF is set (1), the privilege card attached to the card reader / writer 21 has been removed, so the process is terminated after the card flag CF is reset (0). .

On the other hand, if the card flag CF is reset (0) in ST4, the privilege card has not been installed yet, so this process is terminated without doing anything.

When it is determined in ST1 that a key signal is input from the keyboard 22, the input key signal is fetched from the keyboard circuit 17 and the type of the input key signal is determined. Where ST
If it is assumed that the input key signal is 5 due to the input operation of the special treatment key 36, it is recognized that the special treatment level of the customer is designated, and the special treatment key processing shown in FIG. 5 is executed. That is, immediately after entering the preferential treatment key 36, after confirming that the preferential treatment level has been entered by the numeric input key 31, the corresponding preferential treatment flag of the preferential treatment magnification table 47 is set to "1" and the other preferential treatment flags are set. Is reset to "0", and this key processing ends.

If the input key signal in ST5 is not the input of the special treatment key 36 but the input operation of the department key 32 in ST6, it is recognized that the product purchased by the customer has been registered in the department, and FIG. The department key process shown in is executed. That is, the department code set in the input key is checked, and the sales amount and the number of stores of the department registered merchandise are cumulatively registered in the total score area and the total price area of the department totalizer 41 corresponding to the department code. Also, the sales amount is added to the total amount memory 43. Next, it is determined from the specific department flag F1 of the department totalizer 41 whether or not the corresponding department code is the specific department. If the department specific department flag F1 is set to "1", the department is a specific department, so the department point calculation table
The sales amount is added to the total amount area corresponding to the applicable department code of 46. On the other hand, when the department specific department flag F1 is reset to “0”, it is not a specific department, and therefore the department code “00” in the department point calculation table 46 for each department.
The sales amount is added to the accumulated amount area corresponding to. Thereafter, the relevant department code and sales amount are displayed on the display 23, and the printer 25 prints out the receipt and the journal, and the department key processing is completed.

If the input key signal in ST6 is the input operation of the deposit / cash total key 34 instead of the input of the department key 32 in ST6, it is recognized that the product registration closing operation by cash transaction is performed. Then, the deposit / cash total key processing shown in FIG. 7 is executed. That is, first, the contents of the total amount memory 43 are checked. If the content of the total amount memory 43 is "0", an error occurs because the deposit / cash total key 34 has been operated before the product registration. When it is confirmed that the content of the total amount memory 43 is larger than "0", the total amount in the total amount memory 34 is compared with the point reference amount in the reference amount memory 44. If the total amount of money is greater than or equal to the reference amount of money, privilege points are given, so that the department point calculation process is first executed. That is, the cumulative amount of money corresponding to each department in the department point calculation table 46 is divided by the reference amount, the fractional part is rounded down, and the value of each department is added to calculate the point P1 (point calculation means).

Next, the preferential treatment point calculation process is executed for the point P1. That is, the point multiplication factor corresponding to the preferential treatment flag “1” of the preferential treatment ratio table 47 is set to the point P1.
To calculate the point P2.

Next, the time zone flag of the time zone magnification table 48 is "1".
All the set time zones of (1) and the current time counted by the clock circuit 15 are sequentially compared to determine whether or not there is a set time zone to which the current time belongs (time zone determining means). Then, if the current time is within any of the set time zones, the cumulative amount of [multiplication = 0] in the department point calculation table 46 is subtracted from the total amount of money in the total amount memory 43, and this amount G and the corresponding set time are subtracted. The amount of money corresponding to the obi is compared. Then, if the amount of money G is equal to or more than the established amount of money, the time point-based point calculation processing is executed. That is, the point P3 is calculated by multiplying the point P2 by the point magnification corresponding to the corresponding set time zone. Then, the point P3 is added to the point memory 42 as a privilege point. When the current time is outside the set time zone or when the amount G is less than the applicable amount, the point P2 is added to the point memory 42 as a privilege point. (Point output control means) After that, if the card flag CF is set, since the privilege card is attached to the card reader / writer 21, the privilege points in the point memory 34 are written in the privilege card. In addition, change calculation, receipt issuance, drawer opening, etc. are performed as normal depositing processing, and the deposit / cash total key processing is ended. If the total amount of money in the total amount of money memory 43 is less than the point reference amount of money in the reference amount of money memory 44, the privilege points are not given, so the above-mentioned depositing process is immediately executed.

The point memory 42, the total amount memory 43, and the accumulated amount area of the department point calculation table 46 are cleared after the depositing process is completed.

Also, the CPU 11 is "registered" by the mode switch 24.
The program is controlled to execute the timer interrupt process for the time zone flag, for example, every one minute in a state where the mode is selected and designated. That is, when the interrupt process is started, the current time measured by the clock circuit 15 is compared with all the set time zones in which the time zone flag in the time zone magnification table 48 is "1". Then, the time zone flag corresponding to the time zone when the current time has passed the end time is reset to "0".

In this embodiment having such a configuration, each customer carries out shopping by bringing a privilege card for accumulating privilege points issued by the store. Then, at the time of accounting, give the employee a personal privilege card. The clerk who receives the privilege card from the customer mounts the privilege card on the card reader / writer 21 of the electronic cash register. Then, the accumulated bonus points up to the last time recorded on the bonus card are written in the point memory 42. Further, the clerk checks the special treatment level of the customer, and inputs and operates the numeric key 31 and the special treatment key 36 to specify and input the special treatment level of the customer. Then, the preferential treatment flag corresponding to the designated level in the preferential treatment ratio table 47 becomes "1".
Is set to, and other preferential treatment flags are reset to "0". If the preferential treatment level is the same as the immediately preceding customer, this preferential treatment level designation operation can be omitted.

After that, the store clerk inputs and operates the number key 31 and the department key 32 of the keyboard 22 to perform the department registration operation of the product purchased by the customer. Then, the sales amount of each product purchased by the customer is accumulated in the total amount memory 43. Further, the sales amount of the registered merchandise belonging to the specific department is accumulated in the amount accumulation area corresponding to the department code of the department point calculation table 46. On the other hand, the sales amount of the registered merchandise other than the specific department is accumulated in the amount accumulation area corresponding to the department code “00” of the calculation table 46.

When registration of all the products is completed and the customer pays the amount corresponding to the total amount in cash, the clerk inputs the amount to be paid with the number input key 21, and then operates the deposit / cash total key 34. Then, first, the points with respect to the total amount are calculated from the contents of the department point calculation table 46 based on the point reference amount, and the points are corrected by the multiplication factor corresponding to the preferential treatment level. Further, the current time is compared with the set time zone in which the time zone flag in the time zone magnification table 48 is "1", the current time is within the corresponding set time zone, and [multiplication rate = 0] is specified from the total amount. If the amount G obtained by subtracting the cumulative amount of money from the department is equal to or more than the corresponding established amount, the points corrected according to the preferential treatment level are further corrected by the multiplication factor corresponding to the corresponding time zone to be obtained as special points for this shopping. To be On the other hand, when the current time is outside the set time zone or within the set time zone but the amount G is less than the established amount, the points corrected according to the special treatment level are the special points for this shopping. Becomes And
This privilege point is added to the previous accumulated bonus point value in the point memory 42, and the accumulated bonus point value after the addition is recorded on the privilege card possessed by the customer.
When the cumulative point value recorded on the privilege card becomes equal to or larger than a predetermined value, a privilege is given to the customer by issuing a gift certificate according to the point.

Now, it is assumed that each data shown in FIG. 1 is set in the RAM 14. The point reference amount is "100
Yen ”. In this state, for example, at time 21:00, a customer with a special treatment level “2” receives a sales amount of [150 yen] and a department [1].
Belonging to the department A, the product B belonging to the department [2] of the sales amount [200 yen], the product C belonging to the department [3] of the sales amount [300 yen], and the department [5] of the sales amount [200 yen]. Assuming that each of the products D has been purchased, [150 yen] is shown in the accumulated amount area corresponding to the department [00] of the department point calculation table 46, and [200 yen] is accumulated in the accumulated amount area corresponding to the department [02]. However, [300 yen] is stored in the amount accumulation area corresponding to the department [03], and [200 yen] is stored in the amount accumulation area corresponding to the department [05]. Further, [850 yen] is stored in the total amount memory 43. here,
When the registration operation is performed by the key input of the deposit / cash total key 34, first, the point calculation processing for each department is performed by the following equation to calculate the point P1.

Department [00] (150/100) = 1.5 1 × 3 = 3… Department [02] (200/100) = 2 2 × 2 = 4… Department [03] (300/100) = 3 3 × 1 = 3 … Department [05] (200/100) = 2 2 × 0 = 0… P1 = +++ = 10 Next, according to the preferential treatment level [2] of the customer, special treatment points are calculated according to the following formula, and points are given. P2 is calculated.

P2 = P1 × Multiplier for preferential treatment level [2] = 10 × 3 = 30 Next, the current time [21:00] is the time zone magnification table 48
Within the time zone set for and the total amount [850
Cumulative amount [20] of specific department [05] with multiplying ratio [0]
Since the amount [G = 650 yen] obtained by subtracting 0] is equal to or more than the established amount [500 yen] in the relevant time period, time point-based point calculation processing is performed by the following formula to calculate the point P3.

P3 = P2 × magnification of the corresponding set time period = 30 × 2 = 60 Then, the customer is given the above point P3 = 60 as a privilege point for this shopping.

On the other hand, the time when the customer purchased the product is, for example, 18
If the time is 00 minutes, the privilege point is the point P2 = 30 because this time is not the set time zone. If the time is, for example, 24:00, the privilege point P3 is 90 [= 30 × 3] because this time is within the set time period and the corresponding point multiplication factor is [3].

Therefore, for example, in the case of performing store operation in which the point multiplication factor is increased only in an arbitrary time period of the day and the customer who is shopping during that time period is given a greater privilege, the time period ratio table 48 is set. The start time and end time of the time period, the point multiplication factor, and the established amount are set, respectively. Also, the corresponding time zone flag is set to "1". By doing so, the privilege points larger than the privilege points calculated in the other time zones for the same total amount of money are provided to the customer in the time zone. Therefore, it is possible to easily increase the point multiplication factor only in an arbitrary time zone of the day and give a greater privilege to a customer who has shopped during the time zone, and it is possible to expand the store management. Moreover, since it is possible only by setting the necessary data in the setting work before opening the store, it does not hinder the registration work and is practical.

Although a magnetic card is used as the privilege card in the above embodiment, it goes without saying that an IC card can be used by using an IC card interface instead of the card reader / writer 21. Further, in the above embodiment, the privilege points for each customer are cumulatively recorded on the privilege card, but a file memory for each customer is formed in the RAM 14, for example,
You may make it accumulate | store in this file memory for every customer. Further, the present invention can be applied even to the type in which the privilege points are printed out on the receipt for each transaction and are not cumulatively recorded in the memory medium. Furthermore, it goes without saying that the present invention can be applied not only to a single electronic cash register, but also to a POS system in which this electronic cash register is centrally managed by a host controller.

[Effects of the Invention] As described in detail above, according to the present invention, the points commensurate with the total amount of money can be automatically calculated, and the point multiplication factor can be changed in a specific time zone without hindering the registration work. Thus, it is possible to provide a product sales data processing device that can easily expand store operations using privilege points.
