Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a product sales data processing device capable of managing an operator.

[Prior Art] In a store where a large number of store staff (cashers or customer service representatives) are engaged as operators who operate electronic cash registers for registering product sales data, the operator's sales are based on individual sales records. There are many places where management is performed. Therefore, in such stores, an operator uses an electronic cash register that can store sales data for each operator in a built-in memory such as RAM by inputting operator-specific information such as ID No. with a key or ID card. There is a place. In this case, it is possible to obtain a sales record for each operator by printing out a report of sales data by operator for inspection or settlement work.

[Problems to be Solved by the Invention] However, in the conventional electronic cash register of this type, since the storage capacity of the internal storage unit that holds sales data is limited, the number of operators who can manage sales results is limited. was there. For this reason, in stores where many operators are engaged, measures such as collecting sales data for each person and reducing the number of data required for management are taken, and the sales results for each operator must be managed accurately. Was difficult.

Therefore, the present invention is intended to provide a product sales data processing device capable of accurately managing the individual sales results of many operators without being restricted by the storage capacity of the internal storage unit.

[Means for Solving the Problem] According to the present invention, as shown in FIG. 1, the sales data of each product registered by the product registration unit 1 is registered in the sales registration file 2a provided in the internal storage unit 2. In the product sales data processing device in which the card reader / writer 4 is connected to the device main body 3 which collects data, the device main body 3 provides the card number area 2b and the card registration data area 2c in the internal storage unit 2 and Card presence / absence determination for determining whether or not an operator's card 5 storing a unique card number 5a for identifying the operator of the operator and a registration file 5b for accumulating sales data registered by the operator is attached When the commodity registration is performed by the commodity registration means 1 while the means 6 and the judgment means 6 judge that the operator's card 5 is mounted, the commodity is registered. The first card registration processing means 7 for registering the sales data in the registration file 5b of the operator card 5 mounted in the card reader / writer 4 and the judging means 6 judge whether or not the operator card 5 is mounted. At this time, when product registration is performed by the product registration means 1, a temporary storage means 8 for storing the sales data of the product in the card registration data area 2c and a data presence / absence checking means for checking whether the data is stored in the card registration data area 2c 9 and a card number collating means 10 for collating whether the card number 5a in the card data read when the operator card 5 is attached to the card reader / writer 4 matches the card number stored in the card number area 2b. Then, the matching means 10 is used to confirm that the two card numbers match, and the data presence / absence checking means 9 is used to check the card registration data. When it is confirmed that there is data in 2c, after all the sales data stored in this card registration data area 2c are registered in the registration file 5b of the operator card 5 mounted in the card reader / writer 4, the card registration data When the second card registration processing means 11 for clearing the area 2c and the matching means 10 confirm the disagreement of both card numbers and the data presence / absence checking means 9 confirms the existence of the data, the commodity registration by the commodity registration means 1 is prohibited. For the operator who is equipped with the contents of the card number area 2b on the card reader / writer 4 when the product registration prohibition means 12 and the matching means 10 confirm the mismatch of both card numbers and the data presence / absence checking means 9 confirms that there is no data. The card number updating means 13 for rewriting the card number 5a read from the card 5 is provided.

[Operation] With the product sales data processing apparatus of the present invention configured as described above, each operator uses an operator's card in which a unique card number for identifying the operator is stored when starting the product registration business. Attach to the curdley drier. However, at this time, if there is data in the card registration data area of the internal storage unit, product registration is prohibited. If there is no data in the card registration data area, product registration is permitted, and the card number of the operator card attached to the card reader / writer is stored in the card number area of the internal storage unit. That is, the card number area stores a card number that specifies an operator who operates the product sales data processing device of the present invention to start a product registration operation.

Therefore, the operator registers the customer-purchased product by the product registration means. Then, the sales data of the registered merchandise is registered in the sales registration file in the internal storage unit, and is also registered in the registration file of the operator card attached to the card reader / writer. When the operator removes the operator card from the card reader / writer during registration, the sales data for merchandise registration is registered in the sales registration file and stored in the card registration data area. Then, when this operator again mounts his or her own operator card in the card reader / writer, the card number of this operator card and the card number mounted in the card number area match, so the card registration data area All the sales data stored in is registered in the registration file of the operator's card installed in the card reader / writer.

Therefore, the sales data for each operator is aggregated by the operator cards for the number of operators, which stores the unique card number for identifying one operator and the registration file, thereby limiting the storage capacity of the internal storage unit. I do not receive it.

Further, the display controller 46 for driving and controlling the display units of the operator display 24 and the customer display 27 to display characters and the like corresponding to the display data, the key signal from the keyboard 22 is input and processed by the CPU 41. A keyboard controller 47 that converts possible signals, a printer / drawer controller 49 that controls the opening of the drawer 26 while driving and controlling a printer 48 for printing on receipts and recording paper, a clock circuit 50 that measures the current time, and a mode switch An input / output port 51 for inputting signals from the 35 and the first and second selection switches 36, 37, an operator card 52 carried by an operator such as a cashier or a customer service person, or a card for a customer card 53 such as a credit card. An input / output port 54 for inputting / outputting data and the like are connected to the CPU 41 via the bus line 42.

In the RAM 44, as shown in FIG. 5, a return flag F1 indicating that the product is registered for return, a registration flag F2 indicating that registration is in progress, and a card attached to the card reader / writer 25. Card flag that indicates that it is being processed by "1"
A flag memory 61 for storing F3 etc., a number register 62 for temporarily storing number data, an amount totalizer 63 for calculating the total amount of products sold to one customer, and each product registered in the electronic cash register. A sales registration file that aggregates product sales data (sales amount, return amount, discount amount, etc.) by department and transaction (cash payment sales registration, card payment sales registration, return registration, discount registration, etc.) 64, and card N that is the read information from the operator card 52
o., operator name, operation limitation flag, areas C1 to C4 for storing limit amount data, and operator card 52
There is formed a card data buffer 65 and the like including a card registration data area C5 for temporarily storing the sales data obtained by the registration operation when the card is not attached to the card reader / writer 25.

As shown in FIG. 6, the operator card 52 has a card N set as unique information of the operator card.
o.Memory 71, memory 72 for storing the operator name, transaction-specific registration files 73,74 for storing daily and cumulative sales data by transaction, return key 32, discount key 33, cancel key 34 and other predetermined keys A memory 75 that stores operation restriction flags indicating permission / prohibition of registration operations and operations in each business mode respectively, return amount for one return or one customer in return registration, value for one or one customer in discount registration A memory 76 for storing the limit amount data by the registering operation of the withdrawal amount and the like, and a memory 77 for storing the time zone in which the operation of the electronic cash register is permitted are incorporated.

Then, after the predetermined initial process is completed by turning on the power, the CPU 41 executes the main routine according to the flowcharts shown in FIGS. 7 and 8. That is, as a step (hereinafter abbreviated as ST) 1, a card (operator card 52 or customer card 53) is placed in the card reader / writer 25.
Is inserted, and if not inserted, it is determined whether the card flag F3 is set to "1". If not, the process proceeds to ST2. On the other hand, when the card flag F3 is "1", it means immediately after the card is removed, so the registration flag F2 is determined next. If the registration flag F2 is "1", it means that the card has been removed during the product registration. Therefore, the card flag F3 is reset to "0" and the process proceeds to ST2. On the other hand, if the registration flag is not "1", it means that the card is removed after the registration is completed. Therefore, the signal from the second selection switch 37 is read, and if it is an ON signal, the card data buffer 65
After clearing the areas C3 and C4 in which the operation limitation flag and the limit amount data are stored as the predetermined data, the card flag F3 is reset to "0", and the process proceeds to ST2. The second
If the predetermined areas C3 and C4 are cleared when the card is removed after the registration is completed by the ON operation of the selection switch 37, the operation is prohibited until the next card is inserted.

On the other hand, if the card is inserted in ST1, it is determined whether the card flag F3 is set to "1",
If it is "1", the process proceeds to ST2. If it is not "1", it means that the card has just been loaded. Therefore, the data is read from the card to determine whether it is the operator card 52 or the customer card 53. If it is the customer card 53, the card flag F3 is set to "1" and the process proceeds to ST2. On the other hand, in the case of the operator card 52, the card number read from the card.
And whether or not the card number stored in the area C1 in the card data buffer 65 matches (card number collating means). If the card numbers match, it means that the card that was once removed was reattached.
The data in area C5 in the card data buffer 65 (sales data obtained by the registration performed while the card is removed) is stored in the operator's card 52 for the daily total and the cumulative transaction-specific registration files 73, 74, respectively. Add and clear area C5 (second card registration processing means). At this time, if SW2 is ON, the cleared operation limitation flag and the limit amount data are read from the card 52 and re-input. Then, the card flag F3 is set to "1" and the process proceeds to ST2. On the other hand, the card No.
If there is no match, the area of the card data buffer 65
Check if it is stored in C5 (data presence / absence check method). When it is confirmed that there is data, sales data of another operator different from the owner of the operator card 52 inserted in the card reader / writer 25 remains in the area C5, so an error will be described later. Prohibit product registration operation after ST3 (product registration prohibition means). On the other hand, when it is confirmed that there is no data, the storage contents of the corresponding areas C1 to C4 in the card data buffer 65 are read from the card 52 inserted in the card reader / writer 25, the card number, the operator name, If the operation limit flag and the limit amount data are rewritten (card number updating means), set the card flag F3 to "1" and ST2
Go to.

In ST2, the signal from the first selection switch 36 is read to determine whether it is ON or not. If it is OFF, the process proceeds to ST3. If it is ON, if no card is inserted, the process returns to ST1, and if a card is inserted, if the card is an operator card 52, the permitted time zone data is read from the card 52 and the current time is displayed. If the current time is within the permitted time period, the process proceeds to ST3, and if it is outside the permitted time period, the process returns to ST1. In addition,
When the insertion card is the customer card 53, the permission time zone data cannot be read, so the process proceeds to ST3 without checking the time. In ST3, it is determined whether or not there is a key input from the keyboard 22, and if there is no key input, the process returns to ST1, and if there is a key input, the process proceeds to ST4.

In ST4, the business mode selected by the mode switch 35 is determined. Then, in the registration mode, the type of key is determined, and the processing corresponding to the input key as shown in FIGS. 9 to 12 is executed. If it is the inspection mode, the inspection work operation flag of the operation limited flag on the card is recognized, and if the flag is set to "1", the process proceeds to the inspection process, and if it is other than "1", the inspection process is prohibited. . In the register minus mode, the register operation flag of the card operation limited flag is recognized. If the flag is set to "1", the register minus process is performed. If the flag is not "1", the register minus operation is performed. Prohibit processing. It should be noted that each flag is recognized by reading the corresponding flag from the card when the card is inserted, and the card data buffer 65 when the card is not inserted.
Take out the relevant flag from the above and perform.

FIG. 9 is a flowchart showing department key processing in the registration mode. When the department key processing starts, the number register 62
After confirming that the numerical data is stored in, it is determined in ST5 whether the return flag F1 is set to "1". Here, if the return flag F1 is "1", the return item registration process is performed, and if it is other than "1", the sale registration process is performed. In the case of the sales registration processing, the registration flag F2 is set to "1", the number data in the number register 62 is added to the amount totalizer 63 as the sales amount of the sold product, and the sales registration file 64 for each department is added. The sales amount, the sales amount, etc. are cumulatively registered in the relevant department in (1), the department code, the sales amount, etc. are displayed on the displays 24, 27, and the printer 48 prints them on a receipt to finish.

In the case of the return registration process, the return limit amount as the limit amount data on the card is recognized, and it is determined whether or not the number data is less than or equal to this limit amount. Then, if the number data is larger than the limit amount, it is judged as an error and the returned goods registration process is prohibited. If the number data is less than or equal to the return limit, the registration flag is set to "1" because the return registration processing is permitted, and the return amount is subtracted from the total amount in the amount totalizer 63 using the number data as the return amount. In addition, the return amount is subtracted from the sales amount of the corresponding department of the department file in the sales registration file 64, and the return amount is added to the return transaction memory of the transaction file. Next, it is determined whether or not the operator card 52 is inserted in the card reader / writer 25 (card presence / absence determining means), and if inserted, the daily total of the card and the accumulated transaction-specific registration files 73, 74 The return amount is added to the return transaction memory (first card registration processing means), and when the card is not inserted, the return amount is added to the return transaction memory in the card registration data area C5 in the card data buffer 65 (temporary storage). means). Then, the relevant department code,
The return amount (negative display) is displayed on the indicators 24 and 27, the department code, the return amount and the symbol "return" are printed on the receipt, and the return flag F1 is reset to "0" to finish.

FIG. 10 is a flowchart showing the return key process in the registration mode. When the return key 32 is input in the registration mode, the return key operation limitation flag of the operation limitation flag on the card is recognized. If the flag is not "1", it is an error because the input of the return key 32 is prohibited, and if it is "1", the input of the return key 32 is permitted, and therefore the return flag F1
Set to "1" to finish.

FIG. 11 is a flow chart showing discount key processing in the registration mode. When the discount key 33 is entered in the registration mode, the register data is stored in the register register 62, the registration flag F2 is set to "1", and the register data is the sum total value 63. After confirming that the amount is less than or equal to the amount, the discount key operation limitation flag of the operation limitation flag on the card is recognized. If the flag is not "1", it is an error because the input of the discount key 32 is prohibited. If the flag is "1", the input of the discount key 32 is permitted. Move to. Then, the discount limit amount as the limit amount data in the card is recognized, and it is determined whether or not the number data is less than or equal to this limit amount. And
If the number data is larger than the limit amount, it is an error and the discount registration processing is prohibited. If the number data is less than or equal to the discount limit, it is determined that the discount registration processing is permitted, the number data is used as the discount amount, the discount amount is subtracted from the total amount in the amount totaling unit 63, and the sales registration file The discount amount is added to the discount transaction memory of the transaction-specific file in 64. Next, it is determined whether or not the operator card 52 is inserted in the card reader / writer 25 (card presence / absence determining means), and if inserted, the daily total of the card and the accumulated transaction-specific registration files 73, 74 Add the discount amount to the discount transaction memory (first
Card registration processing means), the card registration data area C5 in the card data buffer 65 when the card is not inserted
The discount amount is added to the discount transaction memory in (temporary storage means). After that, the discount amount (negative display) is displayed on the display 24,2
Display it on 7, and print the discount amount and the symbol "Discount" on the receipt to finish.

FIG. 12 is a flowchart showing deposit / cash total key processing in the registration mode. When the deposit / cash total key 30 is input in the registration mode, after confirming that the registration flag F2 is set to "1", it is determined whether or not the register data is stored in the register register 62. . Then, if the number data is present, it is confirmed that the number data is the deposit amount and is equal to or more than the total amount in the amount totalizer 63, and the amount totalizer 63 is stored in the cash settlement transaction memory of the sales registration file 64 for each transaction. Add up the total amount in. Next, it is determined whether or not the operator card 52 is inserted in the card reader / writer 25 (card presence / absence determining means), and if inserted, the daily total of the card and the accumulated transaction-specific registration files 73, 74 The total amount is added to the cash settlement transaction memory (first card registration processing means), and the card data buffer 65 when the card is not inserted.
The total amount is added to the cash settlement transaction memory in the card registration data area C5 in (temporary storage means). After that, the total amount is displayed on the display devices 24 and 27, and the drawer 26 is opened. In addition, the total amount, deposit amount, and change amount are printed on the receipt as necessary, and the operator name on the card is recognized and the operator name, the receipt number, and the current time are printed on the receipt. Issue the receipt. Then, the registration flag F2 is reset to "0", the amount totalizer 63 is cleared, and the process ends.

In the electronic cash register of the present embodiment configured as described above, each operator has an operator card 52, and when operating the electronic cash register, his or her own card 52 is inserted into the card reader / writer 25. Then start the operation. Here, when the operation of registering the sale item for one customer is performed, the total amount of the sale item becomes the sales data and the registration file 73,74 for each transaction of the card 52.
Is accumulated by transaction.

Further, when the return key 32 is operated to perform the return registration, if the return key operation limitation flag of the card 52 is “1” and the return amount is equal to or less than the return limit amount of the card 52, the return registration process is performed. Allowed And the returned amount at this time is the card
It is accumulated in the return transaction memory in the transaction-specific registration files 73, 74 of 52. Similarly, in the case of discount registration by operating the discount key 33, if the discount key operation limitation flag of the card 52 is “1” and the discount amount is less than or equal to the discount limit amount of the card 52. The discount registration process is permitted, and the discount amount at this time is accumulated in the discount transaction memory in the transaction-specific registration files 73 and 74 of the card 52.

If the customer wishes to make a payment using a credit card, he / she removes his / her operator card 52 and inserts the customer card 53 in place of the operator card 52 for registration operation. Then, the total amount of the sold products is held as sales data in the card registration data area C5 in the card data buffer 65, and then the customer card 53 is removed and the own card 52 is reinserted to make a transaction of the card 52. Accumulated for each transaction in the separate registration file 73,74.

As described above, various sales data when each user performs registration operation is accumulated in the operator card 52 owned by each operator, so detailed sales performance management of all operators is possible without being limited by the memory capacity. Can be done. In addition, even in a store where one operator performs registration operations from multiple electronic cash registers, the sales data of the operator is accumulated in his / her own card, so it is only necessary to output the data in the card for each operator. Sales data can be aggregated and the efficiency of inspection and settlement operations can be improved.

Further, in the present embodiment, it is possible to set an operation restriction flag for individually permitting or prohibiting the operation of each key and the execution of each business mode on each operator card 52.
Further, it is possible to set a limit amount for the amount of returned goods at the time of registration of returned goods and the amount of discount at the time of registration for discount. Therefore, the administrator can set the operation restriction flag and the limit amount data arbitrarily according to the years of experience of the operator, etc., so that the operation range can be restricted according to each operator, and the occurrence of an operation error or fraud can be prevented. For example, in the case of prohibiting the return registration or the discount registration for an operator with little experience, the operation restriction flags of the return key 32 and the discount key 33 may be set to "0". Further, even for those operators who are allowed to register, detailed management can be easily performed by changing the limit amount according to the number of years of experience. Moreover, since the operation range can be limited by the card, it is possible to reduce the key position of the mode switch 35.

Furthermore, in the present embodiment, by setting the operable time zone on the operator card 52, it is possible to prohibit the operation of the electronic cash register outside of this time zone, so that it is possible to prevent fraud and enhance safety. obtain.

The present invention is not limited to the above embodiment.
For example, although the DIP switches are used as the first and second switches 36 and 37 in the above embodiment, they may be soft setting switches such as status. Further, in the above-mentioned embodiment, the case where all the operators such as the cashier and the person in charge of hospitality are in possession of the card has been shown. The customer service representative may carry the card. In this case, a person responsible key for identifying the cashier is required. On the contrary, the cashier owns the card and the customer service person is RAM4.
It may be managed by the registration file for each customer service representative of 4. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, product sales data processing capable of accurately managing individual sales results of many operators without being restricted by the storage capacity of the internal storage unit. A device can be provided.
