Japanese Patent Laid-Open No. 10-21472

  However, the above-described operation for making it possible to identify the store clerk to be operated may place a burden on the store clerk, so that the POS register can be operated without such operation. Is also possible. Usually, during the day of business, several clerks may change and operate the POS register. However, any clerk performs this operation because correction, return, etc. may be illegal. I want to know correctly as a history. However, in the operation as described above, the store clerk is not burdened, but there is a problem that the operation of each store clerk cannot be accurately grasped.

The present invention has been made in view of the above points , and provides a sales data processing device and a program capable of appropriately notifying the attention to the operation according to the operation content of each store clerk .

The present invention has been made to solve the above-described problem, and in a sales data processing apparatus for registering product information of a product to be purchased, reading means for reading identification information for identifying a store clerk stored in a non-contact IC And control means for storing information relating to the operation of the clerk in the storage means in association with the identification information, and information relating to the operation of the clerk whose return, correction, or cancellation operation is a preset number of times or more. Extraction means for extracting the identification information associated with the display information, and display means for displaying on the display section a notice that the operation should be noted when the reading means reads the extracted identification information. It is characterized by that.

According to this configuration, if the store clerk is located within a certain range with respect to the device, the store clerk's ID information (identification information) stored in the non-contact IC is read. There is no need for special operations or troublesome operations such as manually inputting ID information or reading a barcode encoded ID information. Further, according to this configuration, since the ID information for each clerk and the information related to the operation of the clerk are stored in association with each other, it is possible to correctly grasp the operation of the clerk without imposing a burden on the clerk. Further, according to this configuration, it is possible to extract a store clerk who has performed an irregular operation such as a return, correction, or cancel operation (an operation that leads to fraud) more than a preset number of times. Moreover, according to this structure, the attention to operation can be notified appropriately according to the operation content of each store clerk. Therefore, according to this configuration, it is possible to reduce irregular operations due to carelessness of the store clerk and to prevent the store clerk from performing unauthorized operations.

  Further, according to the present invention, the control unit is configured such that, after the reading unit reads the first identification information as the identification information, the first identification information is again in an open state in which the apparatus can be operated with the identification information. When reading is performed, the open state with the first identification information read again is continued.

  According to this configuration, when the ID information (identification information) once read is read again during the opening with the identification information, the open state by the ID information is continued, and the sales data processing device once reads While the ID information is being continuously read, it is possible to continue the processing being performed assuming that the same store clerk is operating.

  Further, the present invention is characterized in that, in the control means, when the reading means reads a plurality of the identification information, any one of the plurality of the read identification information can be selected.

  According to this configuration, when a plurality of ID information (identification information) is read, that is, when a plurality of salesclerks are at the cash register, it is possible to select a salesclerk to operate among the plurality of salesclerks. It becomes possible to select.

According to the present invention, a display indicating that the operation should be taken care of is given to the store clerk who has performed the return, correction, or cancellation operation more than a preset number of times. It is possible to appropriately notify the attention to.

It is a schematic diagram which shows the aspect of the POS register different from the POS register shown in FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an outline of a POS register 20 (sales data processing device) in an embodiment of the present invention.
The POS register 20 shown in FIG. 1A acquires identification information that can identify a store clerk using RFID (Radio Frequency IDentification). For example, an RFID tag 11 having identification information (ID information) associated with each store clerk is attached to the name tag 10 possessed by the store clerk (see FIG. 1B). Here, the identification information (ID information) associated with each clerk is identification information (for example, an identification number) that can identify one clerk assigned to one clerk. The POS register 20 includes a reading unit 208 that reads the ID information of the RFID tag 11 through wireless communication. The POS register 20 can be read by a store clerk (depending on the tag frequency band used, for example, 13.65 MHz). If used, the maximum communicable distance is about 1 m at maximum, and normally, the store clerk operating the POS register 20 operates close to the device, so that the corresponding frequency band can be used). Is read from the RFID tag 11. Thereby, the POS register 20 can identify the store clerk to operate using the read ID information.

  Thereafter, the POS register 20 scans the barcode attached to the product to be purchased by the customer by the operation of the store clerk, and registers the product information indicated by the barcode. In addition, when registration of the product information is completed for the barcodes of all the products that the customer intends to purchase, the POS register 20 displays the settlement information including the total purchase amount at a position facing the store clerk. And it displays on the 2nd display part 206 provided in the position which faces a customer.

  Subsequently, the POS register 20 executes a settlement process based on the total purchase amount by the customer through the operation of the store clerk, and prints and issues the settlement information on a receipt as a print medium. The settlement information printed on the receipt includes, for example, purchase information of all products that the customer intends to purchase in a certain transaction, that is, identification information (product code) of the product, quantity information to be purchased, and purchase price information. , Etc. The POS register 20 may print ID information for identifying the store clerk who operated the POS register 20 on a receipt that is a print medium.

  The POS register 20 also reads the read ID information (identification information for identifying the store clerk) and information about the operation after reading the ID information (for example, operation information indicating which operation has been performed, or history of operation information). ) Are stored in association with each other. Here, the information related to the operation of the store clerk is, for example, information related to the operation for registering the product information as described above or the operation for executing the settlement process, or information related to the operation for returning, correcting, or canceling the registered product. Is included.

  As a result, the POS register 20 wirelessly reads the identifiable identification information possessed by the store clerk as the store clerk approaches the cash register, so that it correctly understands which store clerk has performed which operation. be able to. Therefore, the POS register 20 can also grasp operations that lead to fraudulent clerk.

(POS register configuration)
Next, the configuration of the POS register 20 will be described. FIG. 2 is a schematic block diagram showing an example of the configuration of the POS register 20 according to the present embodiment. The POS register 20 includes a CPU (Central Processing Unit) 201 (control means), a ROM 202, a RAM (Random Access Memory) 203, a scanner unit 204, a first display unit 205, a second display unit 206, an operation unit 207, and a reading unit 208. (Reading unit), a printing unit 209, a sound source unit 210, a timer unit 211, a settlement unit 212, and a hard disk 213 (storage unit). These can communicate with each other via a bus 221.

The ROM 202 is a read-only memory and stores a program for operating the POS register 20 in advance.
The CPU 201 is a central processing unit, and controls the operation of the POS register 20 by reading and executing a program stored in the ROM 202.

The scanner unit 204 optically reads a barcode (product code) attached to a product.
The RAM 203 is a memory that can be read and written as needed, and stores various information. For example, the RAM 203 stores purchase information including product information such as a product code read by the scanner unit 204, ID information that can identify a store clerk read by the reading unit 208, operation information related to the operation of the store clerk, and the like. . Note that the RAM 203 stores the ID information read by the reading unit 208 and operation information (information related to the operation) in association with each other under the control of the CPU 201.

The 1st display part 205 is provided in the position which faces a salesclerk, and displays the information with respect to the seller who is a salesclerk, for example, merchandise information extracted from the merchandise master (product name, price information, etc.). The first display unit 205 is a display having a touch panel that accepts operation inputs. For example, when an operation key (preset button) displayed on a screen configuring the first display unit 205 is pressed, an operation input is received for product information (product code or the like) set and registered in advance.
The 2nd display part 206 is provided in the position which faces the customer waiting for goods registration, and displays the information with respect to a customer. For example, the second display unit 206 displays the product information (product name or price information) of each registered product according to the store clerk registering the product that the customer intends to purchase, and all registration is completed. Then, the total purchase price is displayed.

  The operation unit 207 includes operation means for operating the POS register 20 (for example, a completion key declaring completion of product registration, a correction key, a preset key, a numeric key, a gift certificate key, and the like). For example, when the seller presses an operation key (preset key), the operation unit 207 receives an operation input for product information (product code or the like) preset and registered corresponding to the key. Note that the operation means of the operation unit 207 may be arranged as a mechanical button, or may be arranged on a touch panel provided on the display surface of the first display unit 205.

  The reading unit 208 reads ID information (identification information) from the RFID tag 11 possessed by the store clerk by wireless communication using RFID. For example, when a store clerk is in a range where ID information can be read from the RFID tag 11, the reading unit 208 reads the ID information from the RFID tag 11 attached (attached) to the name tag 10 possessed by the store clerk. That is, the reading unit 208 reads the ID information of the store clerk who performs an operation on the POS register 20 by wireless communication using RFID.

  Here, the range in which the reading unit 208 can read the ID information from the RFID tag 11 is a distance in which the reading unit 208 can wirelessly communicate with the RFID tag 11, for example, a distance of about several tens cm to 1 m as described above. It is. The reading unit 208 can wirelessly communicate with the RFID tag 11 in a predetermined range on the facing side, and is most easily read when the RFID tag 11 is in the front, and becomes difficult to read as the distance from the front is increased. Therefore, in the example illustrated in FIG. 1, the reading unit 208 is provided so as to face the store clerk who operates the POS register 20. Thus, when the store clerk is positioned in front of the POS register 20 for operation, the RFID tag 11 is necessarily read by the reading unit 208.

As described above, the position of the reading unit 208 is preferably arranged at a position more suitable for the relative position with the RFID tag 11 possessed by the store clerk. However, as described above, the store clerk usually has the front of the POS register 20. The reading unit 208 is preferably located on the front surface of the apparatus.
Therefore, the reading unit 208 may be arranged at a position other than the position shown in FIG. 1 according to the position where the RFID tag 11 is held. The reading unit 208 may be integrated with the POS register 20, or may be configured separately from the POS register 20 and connected by wire or wirelessly.

  The sound source unit 210 generates sound by an operation input. The sound source unit 210 outputs a signal sound when, for example, reading by the scanner unit 204 is normally performed or when a completion key is pressed.

  The printing unit 209 prints settlement information and the like on the receipt 41 that is a printing medium. The receipt is printed with, for example, printing date and time, product name or product type, product purchase quantity, purchase price information (price information), and ID information for identifying the clerk who operated the POS register 20. Yes.

  The timer unit 211 sequentially generates time information. The time information may include date information in addition to the hour and minute. The timer unit 211 outputs the measured time information to, for example, the CPU 201, the first display unit 205, the printing unit 209, and the hard disk 213.

  The settlement unit 212 includes a change bill machine, a credit card reader, an electronic money reader, and the like, and a control unit thereof. The POS register 20 uses the settlement unit 212 to execute a settlement process using cash, a credit card, or electronic money. For example, the settlement unit 212 performs a settlement with cash using a change bill machine, and outputs a result of the settlement (for example, information indicating whether or not a settlement has been established) to the CPU 201 via the bus 221. The change bill machine includes a bill insertion slot for inserting and discharging bills, a coin insertion slot for inserting coins, and a change discharge outlet for discharging change.

  Further, the settlement unit 212 performs settlement by credit card with a credit card reader, and outputs a result of the settlement to the CPU 201 via the bus 221. Further, the settlement unit 212 performs settlement with electronic money by the electronic money reader, and outputs the result of the settlement to the CPU 201 via the bus 221.

The hard disk 213 reads the information temporarily stored in the RAM 203 from the RAM 203 and stores it. For example, the hard disk 213 reads purchase information, ID information, operation information, and the like temporarily stored in the RAM 203 from the RAM 203 and stores them at a predetermined timing under the control of the CPU 201. Here, the hard disk 213 reads the ID information and the operation information associated with each other temporarily stored in the RAM 203 from the RAM 203 and stores them.
Also, the hard disk 213 stores the time information input from the timer unit 211 and the ID information read by the reading unit 208 in association with each other. Also, the hard disk 213 stores time information input from the timer unit 211 and operation information in association with each other.

(Process to identify clerk)
Next, with reference to FIG. 3, the operation of the process in which the POS register 20 identifies the operation for each clerk will be described. FIG. 3 is a flowchart showing an example of processing operation in the POS register 20 according to the present embodiment. In this figure, after the power is turned on, the POS register 20 reads the ID information of the RFID tag 11 (non-contact IC) possessed by the store clerk, and shifts to an operable state based on the read ID information. (Transition to the logged-in state by the read ID information).

  Note that the process in which the POS register 20 shifts to an operable state based on the ID information is referred to as “open process” in the following description. On the other hand, the process in which the POS register 20 shifts from a state where the POS register 20 is logged in based on the read ID information (open state) to a state where the POS register 20 is logged off (a state where operation cannot be performed until the user logs in again) is a closing process. Called. That is, when each store clerk operates the POS register 20, by performing “open processing” and “close processing”, it is determined that the operation during that time is performed by the store clerk of the identified ID information. be able to.

First, the reading unit 208 of the POS register 20 executes processing for reading ID information from the RFID tag 11 (step S101).
Then, the POS register 20 determines whether or not ID information has been acquired (step S102). If YES in step S102, that is, if there is a store clerk possessing the RFID tag 11 within the readable range of the reading unit 208, the POS register 20 acquires the ID information by the reading unit 208, and proceeds to step S103. . If NO in step S102, that is, if there is no store clerk possessing the RFID tag 11 within the readable range of the reading unit 208, the POS register 20 repeats the ID information reading process because the reading unit 208 cannot acquire the ID information. Run.

  In step S103, the POS register 20 executes an open process based on the read ID information. For example, the POS register 20 executes a login process with the read ID information, updates the data as the ID information of the store clerk who operates the ID information, and permits the operation to the POS register 20. Then, for example, information (not shown) indicating that the open process has been executed with the read ID information and the time at that time are stored in the ID information and operation information file in FIG. 7 described later.

  Subsequently, the POS register 20 executes a transaction start process in accordance with a store clerk's operation on the product that the customer intends to purchase (step S104). This transaction is a process corresponding to each operation by accepting operations related to the registration of the product information (product code) of the product that the customer intends to purchase or the return, correction, cancellation, or settlement of the registered product. Is to execute.

  The store clerk performs operations related to registration of product information of a product to be purchased by the customer or returned, corrected, canceled, or settlement of the registered product, and the touch panel or operation of the scanner unit 204 and the first display unit 205. This is performed using the unit 207. In response to these operations, the POS register 20 acquires operation information indicating the content of the operation under the control of the CPU 201 (step S105), and stores the acquired operation information in the RAM 203 in association with the ID information (step S106). ).

  Subsequently, the reading unit 208 executes a process of reading ID information from the RFID tag 11 (step S107). Note that the process of reading the ID information by the reading unit 208 is a process for identifying the store clerk to operate in real time, and may be repeatedly executed at predetermined intervals under the control of the CPU 201.

The POS register 20 determines whether or not the same ID information as the currently logged-in ID information can be read in the ID information reading process in step S107 (step S108). If YES in step S108, that is, if it is determined that the same ID information can be read, the process proceeds to S109. If NO, the process proceeds to S110.
In step S109, since it is determined in step S108 that the store clerk at the time of login continues to operate, the operation for the POS register 20 is continuously permitted (step S109). That is, when the reading unit 208 reads the ID information of the RFID tag 11 as the identification information for identifying the store clerk and performs the opening process and then reads the same ID information again, the POS register 20 ignores the ID information read again. Continue the currently executed process.

  Subsequently, the POS register 20 determines whether or not one transaction has been terminated by the operation of the store clerk (step S130). Whether or not this transaction has ended is determined by registering the product information of the product purchased by the customer, and the settlement process based on the registered product information (displaying the total purchase price of the product to the customer, This means whether or not the payment processing is completed. In addition, when the transaction is terminated, the transaction may be interrupted for the convenience of the customer or the store clerk in addition to the case where the settlement process is completed.

  If NO in step S130, that is, if it is determined that the transaction has not ended, the POS register 20 returns to the process of step S105, and sequentially acquires the operation information operated by the store clerk, and the acquired operation information Is stored in the RAM 203 in association with the ID information.

  On the other hand, if YES in step S130, that is, if it is determined that the transaction has ended, the POS register 20 reads the ID information and the operation information associated with the ID information from the RAM 203, and the read ID information and Operation information is stored in the hard disk 213 so that the correspondence can be understood. In other words, the POS register 20 stores a history of operation information in which the ID information and the operation information are associated with each other in the hard disk 213 so that the details of the operation performed by each store clerk can be understood later (step S131).

  Thereby, the POS register 20 can confirm the operation content performed by each store clerk later. The POS register 20 associates, for example, operation information indicating an operation related to return, correction, or cancellation of a registered product with the ID information of the store clerk who performed the operation. And stored in the hard disk 213. As a result, the POS register 20 causes any store clerk to perform an operation (irregular operation) that corrects the processing once performed among the operations performed by the store clerk, that is, an operation that may lead to fraud. It is possible to correctly grasp whether it has been done.

Next, in step S132, it is determined whether or not the barcode of the product purchased by the next customer has been read. If YES in step S132, the process returns to step S105. If NO in step S132, the process proceeds to step S133.
That is, in S132, when the previous customer's transaction ends in S131, and the bar code of the product purchased by the next customer is scanned in S132, a new transaction code incremented by “1” is generated. The new transaction code corresponds to the ID information, and the product code registered in the transaction is sequentially stored.

  Next, the POS register 20 executes a close process and ends the process (step S133). Note that the POS register 20 is executed by, for example, touch-selecting a mode for performing the closing process displayed on the first display unit 205, and information indicating that the closing process has been performed with the ID information of the store clerk and its information The time is stored in a file (not shown) of ID information and operation information in FIG. That is, both the open process and the close process are stored together with the ID information for executing them, and the store clerk who performed the operation during that time can be specified. In the closing process, the transaction data registered by the store clerk from the opening process in step S103 to the closing process in step S132 is, for example, the ID information and operation information in FIG. The file is referenced and output to the receipt.

  By the way, a store clerk may leave the POS register 20 for the purpose of exchanging or confirming a product while operating the POS register 20. In such a case, if another store clerk or a person other than the store clerk operates the POS register 20 while the store clerk is away from the cash register, it is impossible to correctly know who the operation was. Therefore, the POS register 20 prohibits the operation so that the POS register 20 cannot be operated when the store clerk is absent.

  Specifically, the POS register 20 determines that the same ID information as the currently logged-in ID information cannot be read, for example, in the case of NO in step S108 when the clerk who is operating is away and is absent. In this case, the POS register 20 sets the operation for the POS register 20 to be disapproved (step S110), and detects that the store clerk is absent (step S116). For example, the POS register 20 is set so that an operation using the scanner unit 204 or an operation on the touch panel of the first display unit 205 or the operation unit 207 is invalidated. As described above, when the reading unit 208 cannot read the ID information (ID information currently logged in) once read by the reading unit 208, the POS register 20 does not permit the operation on the POS register 20. Thereby, the POS register 20 can prohibit operations other than the clerk when the logged-in clerk is absent.

  Next, the POS register 20 detects the clerk's absent time based on the time information measured by the timer unit 211, and determines whether or not the clerk's absent time has exceeded a predetermined time (step S117). The predetermined time is a time set in advance as the maximum absence time for determining that the process is to be interrupted when the salesclerk does not return after the salesclerk is absent.

  If NO in step S117, that is, if it is determined that the absence time of the store clerk has not exceeded a predetermined time, the POS register 20 returns the process to step S107, and is the same as the ID information currently logged in in S108. It is determined whether or not the reading unit 208 has read the ID information. Here, when the store clerk returns, the POS register 20 determines that the reading unit 208 has read the same ID information as the currently logged-in ID information, and permits the operation to the POS register 20. Continue transaction processing. That is, the POS register 20 permits an operation to the POS register 20 when the ID information (ID information that is currently logged in) once read by the reading unit 208 cannot be read and is read again. As a result, the returned clerk can resume (continue) the operation on the POS register 20 again without performing a special operation for resuming the operation.

  On the other hand, if YES in step S117, that is, if the clerk does not return, and if the clerk's absence time has exceeded a predetermined time in step S117, the POS register 20 proceeds to step S131 as a timeout. (Step S118). Then, the POS register 20 reads the ID information and the operation information so far from the RAM 203 and stores them in the hard disk 213 (step S131).

  As described above, the POS register 20 reads ID information for identifying a store clerk from the RFID tag 11 by wireless communication, and stores operation information related to the operation of the store clerk in the hard disk 213 in association with the read ID information. Thereby, the POS register 20 can store the operation contents for each store clerk. The POS register 20 prohibits the operation of the POS register 20 when the reading unit 208 cannot read the logged-in ID information, that is, when the operating clerk is absent. As a result, the POS register 20 can prohibit the operation of a person other than the store clerk when the store clerk who is operating is absent. Therefore, the POS register 20 can be used by any store clerk without any special operation or troublesome operation such as inputting a number that can identify the store clerk or scanning a barcode before starting the operation at the cash register. It is possible to correctly grasp whether the operation has been performed. Further, when the ID information of the store clerk cannot be read by the reading unit 208 for a certain time or longer, the operation of the store clerk is automatically closed, so that the next person who operates newly can quickly operate. . When the close process is performed, information indicating that the close process is performed with the ID information of the store clerk and the time are stored in, for example, an ID information and operation information file (not shown) in FIG. 7 described later. Is done.

  In addition, the information related to the store clerk's operation includes information related to a return, correction, or cancellation operation. As a result, the POS register 20 can correctly grasp the store clerk who has performed an irregular operation such as a return, correction, or cancellation operation (an operation that leads to an unauthorized operation).

  In the process shown in FIG. 3, after the POS register 20 is activated, a screen for registering ID information is displayed first, and a touch operation for an operation key for starting registration is detected, and then the RFID tag 11 in step S101 receives an ID. You may make it start the process which reads information.

(Processing when other clerk is detected when the clerk is absent)
Next, with reference to FIG. 4, processing when the POS register 20 acquires ID information of another clerk while the clerk who was operating is absent will be described. The process shown in FIG. 4 differs from the process shown in FIG. 3 in that the processes of steps S115, S120, S121, S122, and S123 are added. In FIG. 4, parts corresponding to the respective processes in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted.

  As described with reference to FIG. 3, the POS register 20 acquires the ID information in step S102, determines in step S108 whether the acquired ID information is continuously acquired, and determines the ID information currently logged in. When it is determined that the same ID information cannot be read (in the case of NO in step S108), that is, when the clerk who is operating is away and is absent, the operation for the POS register 20 is set to be disapproved (step S110). ). Next, the POS register 20 determines whether or not ID information (other ID information) other than the currently logged-in ID information can be read in the ID information reading process in step S107 (step S115).

  If it is determined in step S115 that no ID information other than the currently logged-in ID information has been read (in the case of NO), it is determined that neither the store clerk who is operating nor any other store clerk is present, The POS register 20 proceeds to the processing of steps S116, S117, and S118 described with reference to FIG.

  On the other hand, if it is determined in step S115 that ID information other than the currently logged-in ID information (other ID information) has been read (in the case of YES), the POS register 20 displays the clerk who was operating (currently logged in). It is detected that there is another store clerk different from the store clerk) (step S120). In this case, the POS register 20 determines whether or not to change the operation to the POS register 20 to another detected store clerk (store clerk with detected ID information) instead of the currently logged-in store clerk (desired to change the operation). A selection screen for selecting whether or not to perform is displayed on the first display unit 205 (step S121).

  For example, in step S121, when the POS register 20 cannot read the ID information once read by the reading unit 208 and then reads ID information (ID information of another clerk) different from the ID information, the POS register 20 It is possible to select whether or not to change the operation for (whether or not to change the clerk to operate). That is, the POS register 20 enables the store clerk to select whether or not to change the operation. For example, this allows another detected store clerk different from the currently logged-in store clerk to change whether or not to change the operation on the POS register 20 (whether or not to change the operation) from the above selection screen. It can be selected by inputting an operation.

  Subsequently, after the ID information once read by the reading unit 208 cannot be read, the POS register 20 performs an operation on the POS register 20 when reading ID information (ID information of other clerk) different from the ID information. It is determined whether or not to permit (determination means). For example, when the POS register 20 is selected in step S121 to change the operation on the POS register 20 (selection to change the operating clerk, selection to change the operation), the clerk can be replaced in advance. Whether or not the ID information read in step S115 is the ID information of a store clerk that can be replaced in the middle of the stored information (whether or not the operation is permitted). (Step S122). This makes it possible to suddenly set the POS register by setting in advance ID information of an authorized store clerk such as a skilled store clerk or store manager without setting ID information of a store clerk who is unfamiliar with operation even for the same store clerk. Since the clerk entering the operation 20 becomes a clerk accustomed to the operation, the customer can quickly register the purchased product.

  As described above, in the case where a selection for changing the operation is made without limiting the number of salesclerks who can be changed on the way, the POS register 20 is operated by the salesclerk of the other clerk's ID information. May be permitted. In addition, when the POS register 20 cannot acquire the same ID information in step S108 and the ID information of another store clerk is read in step S115 after a predetermined time has elapsed, the operation is changed in step S121. May be always permitted without making a determination in step S122. For example, when the same store clerk cannot return after a certain period of time, the other store clerk may try to operate instead because the store clerk does not return. In such a case, even if an clerk who is not set in advance even though the POS register 20 can be handled originally tries to operate instead, it is determined in step S122 that the clerk ID information is not set. Thus, it is possible to prevent the POS register 20 from being operated.

  If it is determined in step S122 that the operation on the POS register 20 is permitted (in the case of YES), the POS register 20 updates the currently logged-in ID information to newly acquired ID information different from the ID information. (Step S123). That is, the POS register 20 once closes the process by the store clerk's operation of the ID information that is currently logged in, determines that the store clerk operating to another store clerk who newly acquired the ID information has changed, Open processing is performed according to the store clerk's ID information. The POS register 20 changes the processing so as to store operation information indicating the contents of subsequent operations on the POS register 20 in association with the newly acquired ID information. Then, the POS register 20 advances the processing to step S109 and permits the operation on the POS register 20.

On the other hand, if it is determined in step S122 that the operation to the POS register 20 is not permitted (in the case of NO), the POS register 20 advances the process to step S116, and similarly to the process described with reference to FIG. Execute the process when is absent. (For example, the display of the first display unit 205 provided at the position facing the store clerk may be controlled so as not to be displayed so that key operations or the like cannot be performed.)
That is, the POS register 20 continues to control the operation to the POS register 20 to be disapproved, and repeatedly executes the process of reading the ID information of the RFID tag 11 until the clerk absence state has elapsed for a predetermined time or more. Further, the POS register 20 executes a closing process when the clerk is absent for a predetermined time or longer.

  Thus, when the POS register 20 cannot read the ID information once read by the reading unit 208 and then reads ID information different from the ID information (ID information of another store clerk), the POS register 20 operates on the POS register 20. Can be selected (whether or not to change the clerk to operate). Thus, another store clerk can perform an operation on the POS register 20 in which the store clerk is absent by selecting to permit the operation on the POS register 20. Further, the POS register 20 updates the ID information of the operating clerk even when the operating clerk is changed to another clerk different from the currently logged in clerk. Information can be stored in association with the updated ID information.

  Further, the POS register 20 executes a closing process when a predetermined time (preset time) has elapsed since the ID information once read by the reading unit 208 cannot be read. Thereby, the POS register 20 can execute an open process in response to reading the ID information of the other store clerk described above and permit an operation on the POS register 20. Therefore, the POS register 20 can once terminate the process when the clerk who has been operating is absent for a long time, and even other clerks do not perform any special or troublesome operations. Allow operations to be performed.

  When the clerk who first logs in again operates the POS register 20 after another clerk starts operating, the clerk who logs in first becomes the handling of the other clerk, and the operation is performed on the selection screen described above. By selecting to allow, the POS register 20 can change the clerk back to the clerk who logged in first (changing and updating the ID information).

  Note that when the reading unit 208 reads a plurality of pieces of ID information, the POS register 20 may select any one of the read pieces of ID information. For example, there are cases where two salesclerks, a clerk who operates a cash register and a clerk who packs a purchased product in a bag, are within a readable range of the reading unit 208 of the POS register 20. In such a case, the reading unit 208 may read the ID information from the RFID tag 11 possessed by each of the two store clerks. Therefore, for example, the POS register 20 displays on the first display unit 205 a selection screen on which one of the read ID information of the two salesclerks can be selected. As a result, even when two clerks, a clerk who operates the POS register 20 and a clerk who packs a purchased product in a bag, are at the cash register, an operation for selecting the ID information of the clerk who operates the POS register 20 is performed. By the clerk, the POS register 20 can correctly acquire the ID information of the clerk who operates the cash register.

(Display example when ID information is read)
Next, a display example of the first display unit 205 when the ID information is read in step S101 of FIG. 3 will be described with reference to FIG.

  In the example illustrated in FIG. 5, the product is displayed on the first display unit 205 configuring the touch panel, and the store clerk can register the desired product by touching a corresponding portion of the touch panel. Further, the POS register 20 displays a message 1101 related to processing at the upper left of the screen of the first display unit 205. For example, the POS register 20 displays “ID information has been acquired” in the message 1101 as information for notifying that the ID information has been read from the RFID tag 11. Further, the POS register 20 displays the read ID information (such as the store clerk ID number “0001”) on the employee number 1102 at the lower left of the screen of the first display unit 205. The POS register 20 executes an open process in response to reading the ID information.

(Operation example of POS register)
Next, with reference to FIG. 6, an example of the operation of the clerk on the POS register 20 will be described. This figure shows the first display section when the product registered immediately before is incorrect registration or when the customer cancels the purchase and corrects the registration of the product (cancels the previous registration) A display example 205 is shown.

  In FIG. 6A, the POS register 20 stores the product name “lettuce”, the lettuce purchase unit price “¥ 150”, and the purchase based on the product code read by the scanner unit 204 (“lettuce” in this figure). The number (the number of points purchased) “1” is displayed on the first display unit 205.

  FIG. 6B shows a display example when the correction process is executed by the store clerk touching the “correction” key. In response to detecting a touch operation on the “correction” key, the POS register 20 executes a correction process for correcting (cancelling) the purchase unit price and the number of purchases of the product “lettuce” registered immediately before. . In the example shown in this figure, the POS register 20 uses the product price to be corrected (product name “lettuce”) and the purchase unit price “− ¥ 150” as information indicating that the registered purchase unit price is canceled in accordance with the correction process described above. ”And the purchase quantity (purchase score)“ 0 ”are displayed on the first display unit 205 as information indicating that the purchase quantity (purchase score) is cancelled. As described above, the POS register 20 stores the operation information (in this case, information indicating “correction operation”) indicating the contents of the operation of the store clerk in association with the ID information.

(Example of stored ID information and operation information file)
Next, an example of ID information and operation information files stored in the hard disk 213 will be described with reference to FIG. In this figure, for each transaction, the clerk's ID information (clerk identification information), the product code of the purchased product in the transaction, the purchase quantity, the clerk's operation information in that transaction, and the date and time (time) at which that transaction was completed Information) is stored. In this figure, as operation information, operation information related to “return”, “correction”, and “cancellation”, which are irregular operations that are not normal operations, is shown as an example, but other operation information (for example, All the operation information) may be added to the file and stored.

  As described above, the POS register 20 executes the open process by acquiring the clerk's ID information, and stores the acquired ID information as information for identifying the clerk who operates the POS register 20. When the transaction is started, the POS register 20 stores operation information indicating the operation content operated for each transaction in association with the ID information. The POS register 20 stores operation information for each registered operation of each purchased product in the transaction in association with the ID information.

  In the example of this figure, the POS register 20 extracts the operation information related to “cancel”, “correction”, and “return” from the operation information for each registration operation of each purchased product. Operation information regarding “correction” and “cancel” is stored in association with the ID information. In the transaction with the transaction code “0001”, the information “1” indicating that the store clerk with the ID information “0001” has performed an operation of “correcting” the registered product in the operation of registering the product with the product code “100001”. Is stored. In the operation information of “Return”, “Correction”, and “Cancel”, “1” indicates that each operation is performed, and “0” indicates that each operation is not performed.

  Further, in the transaction with the transaction code “0003”, information indicating that the store clerk with the ID information “0001” has performed an operation of “returning” the registered product in the operation of registering the product with the product code “100015”. Is remembered. Further, in the transaction with the transaction code “0003”, information indicating that the store clerk operating the POS register 20 has changed from the store clerk with the ID information “0001” to the store clerk with the ID information “0002” is stored. Yes. The operation up to registering the product with the product code “100015” is the operation of the store clerk with the ID information “0001”, and the operation after registering the product with the product code “100006” is the operation of the store clerk with the ID information “0002”. . In this way, it is possible to correctly understand which store clerk has performed which operation.

  It should be noted that the POS register 20 may extract ID information associated with information related to the operation of the store clerk who performs the “return”, “correction”, or “cancel” operation more than a preset number of times. Then, when the reading unit 208 reads the extracted ID information, the POS register 20 may display on the first display unit 205 a notice that the operation should be noted. Here, the above-mentioned number of times set in advance is the number of times set in advance as the number of times it is determined that it is necessary to pay attention to the fact that there are many irregular operations for the store clerk.

For example, the POS register 20 displays a display indicating that the store clerk should pay attention to the operation when the store clerk who performs irregular operations such as “return”, “correction”, or “cancel” operates. 1 is displayed on the display unit 205.
As a result, the POS register 20 can appropriately notify the attention to the operation according to the operation contents of each store clerk. Therefore, the POS register 20 can reduce irregular operations due to carelessness of the store clerk, and has an effect of preventing the store clerk's unauthorized operation.

(Another aspect of the POS register)
Next, a POS register 20 (sales data processing apparatus) having a mode different from the POS register 20 shown in FIG. 1 will be described with reference to FIG. The POS register 20 shown in this figure includes a checker unit 30a that scans a barcode attached to a product to be purchased by a customer and registers product information indicated in the barcode, and a checkout process for the registered product. The cashier part 30b to be performed is separated. One store clerk may operate both the checker unit 30a and the cashier unit 30b, but two store clerk may share the operations of the checker unit 30a and the cashier unit 30b.

  In the example shown in this figure, the checker unit 30a includes a reading unit 308a, and the cashier unit 30b includes a reading unit 308b. The reading unit 308a reads ID information from the RFID tag 11 possessed by a store clerk who operates the checker unit 30a. The reading unit 308b reads ID information from the RFID tag 11 possessed by a store clerk who operates the cashier unit 30b. Thereby, the checker part 30a can identify the salesclerk who operates the checker part 30a, and the cashier part 30b can identify the salesclerk who operates the cashier part 30b. Therefore, even when two store clerks operate the checker unit 30a and the cashier unit 30b, it is possible to correctly identify which store clerk operated each operation on the checker unit 30a and the cashier unit 30b ( Can grasp). Further, as described above, even in the POS register 20 of the two-person system, the RFID tag 11 possessed by the store clerk who operates the checker unit and the store clerk who operates the cashier unit is read by the reading unit 308b at one location of the cashier unit. Each of the read ID information may be assigned with a checker part and the other as a cashier part.

(Other configuration examples)
The POS register 20 of the present embodiment may be configured as a POS (Point Of Sales) system in which a plurality of POS registers 20 (20a, 20b, 20c, 20d,...) Are connected via a network. .

  The store controller, which is a computer that controls the entire POS system, has various product masters (product files) including product information such as product information (product code), price information (purchase unit price information) and product name information for each product. The information is memorized. The store controller transmits the product master to each POS register 20. The product master is an electronic information file that stores product information including a product code, a product name, and a price of each product. The product code is information for identifying each product, for example, a JAN (Japan Article Number) code.

  The plurality of POS registers 20 (20a, 20b, 20c, 20d,...) Are connected to a store controller via a LAN (Local Area Network). Here, each of the plurality of POS registers 20 includes a communication unit for connecting to a LAN in addition to the configuration shown in FIG. However, the POS register 20 may be not connected to the store controller. For example, a POS register 20 provided with a storage medium in which a product master is stored, for example, a CD-ROM (Read Only Memory) is included, and the POS register 20 may not be connected to the store controller. The plurality of POS registers 20 may be connected to the store controller via either a wireless LAN or a wired LAN, or may be connected by a communication method other than the LAN.

  In the POS system configured as described above, the ID information stored in the RAM 203 or the hard disk 213 of the POS register 20 shown in FIG. 2 and the operation information associated with the ID information are stored in the storage unit in the store controller, or The configuration may be stored in a server (not shown) or the like connected via a LAN.

  As described above, the POS register 20 wirelessly reads the identifiable ID information (identification information) possessed by the store clerk as the store clerk approaches the cash register. It is possible to correctly grasp whether the operation has been performed.

  Note that the POS register 20 associates ID information (identification information) for identifying a clerk from the RFID tag 11 by radio communication with the reading unit 208 (reading means) and information related to the operation of the clerk in association with the read ID information. And a CPU 201 (control means) for controlling to store the data in a hard disk 213 (storage means). As a result, the POS register 20 allows the store clerk to input a number that can identify the store clerk or scan a bar code that can identify the store clerk before starting the operation at the POS register 20. Without any troublesome operation, it is possible to correctly grasp which store clerk has performed which operation.

  In addition, since the information related to the operation of the store clerk includes information related to the return, correction, or cancellation operation, the POS register 20 causes the irregular operation such as the return, correction, or cancellation operation (illegally). It is possible to correctly grasp the store clerk who performed the operation to connect. Therefore, the POS register 20 can reduce irregular operations due to carelessness of the store clerk, and has an effect of preventing the store clerk's unauthorized operation.

  Further, when the reading unit 208 reads the logged-in ID information (first identification information) again, the POS register 20 sets the read ID information (first identification information) as invalid identification information. As a result, the sales data processing device is executing as if the same logged-in store clerk is operating while the ID information (first identification information) once read is continuously read. Processing can continue.

  The POS register 20 operates the POS register 20 when the reading unit 208 cannot read the logged-in ID information (first identification information), that is, when the operating clerk is absent. Disallow. As a result, the POS register 20 can prohibit the operation of a person other than the store clerk when the store clerk who is operating is absent. Therefore, since the POS register 20 is not operated by another person while the operating clerk is not present, the operating clerk can be correctly grasped.

  Further, when the ID information (first identification information) is read again after the reading unit 208 cannot read the logged-in ID information (first identification information), the POS register 20 reads the ID information (first identification information) again. Allow operation. As a result, the store clerk can resume the operation without performing a special operation or a troublesome operation.

  Further, the POS register 20 cannot read the logged-in ID information (first identification information) read by the reading unit 208, and then the other clerk's ID information (first identification information) different from the ID information (first identification information). When the second identification information) is read, it is possible to select whether or not to permit the operation on the POS register 20. For example, the POS register 20 displays a selection screen that allows selection of whether or not to permit the operation. As a result, when another store clerk comes, it is possible to select permission or disapproval of the operation on the sales data processing device depending on whether the store clerk operates on behalf of the store clerk or not. Further, the POS register 20 can update (change) the ID information of the store clerk who operates with the selection that the operation is permitted when another store clerk changes the operation.

  Further, the POS register 20 reads the ID information (second identification) of another store clerk when a preset time has elapsed since the reading unit 208 could not read the logged-in ID information (first identification information). In response to reading (information), an operation on the POS register 20 is permitted. For example, the POS register 20 executes the close process when the clerk who has been operating has been absent for a long time. Thus, the POS register 20 can be operated without any special operation or troublesome operation even by another store clerk when the store clerk who has been operating is absent for a long time.

  Further, the POS register 20 reads a plurality of ID information (identification information) when the reading unit 208 reads a plurality of ID information (identification information), that is, when a plurality of shop assistants are in the vicinity of the POS register 20. Either of these can be selected. Thereby, when the POS register 20 reads a plurality of pieces of ID information (identification information), that is, when a plurality of salesclerks are in the vicinity of the POS register 20, it is possible to select a salesclerk to operate among the plurality of salesclerks. is there.

  Further, the POS register 20 extracts ID information (identification information) associated with information related to a store clerk's operation that is equal to or greater than a preset number of operations for return, correction, or cancellation (extraction means), It is executed under the control of the CPU 201 (control means). As a result, the POS register 20 can extract a store clerk who has performed an irregular operation such as a return, correction, or cancel operation (an operation that leads to unauthorized access) a predetermined number of times or more. Therefore, it is possible to correctly grasp which store clerk has performed an operation that leads to an illegal connection.

  Further, the POS register 20 displays, on the first display unit 205 (display unit), an indication that the operation should be noted when the reading unit 208 reads the ID information (identification information) extracted by the extraction unit. To do. As a result, the POS register 20 reads the ID information of a clerk who has performed an irregular operation such as a return, correction, or cancellation operation (an operation that leads to an unauthorized operation) a predetermined number of times or more. The store clerk can be notified with an indication that the operation should be noted. Therefore, the POS register 20 has an effect of preventing an erroneous operation caused by carelessness of a store clerk or an operation that leads to an unauthorized operation.

  Note that a part of the POS register 20 in the above-described embodiment, for example, the CPU 201 may be realized by a computer. In that case, the program for realizing the control function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read by a computer system and executed. Here, the “computer system” is a computer system built in a part of the POS register 20 and includes an OS and hardware such as peripheral devices.

  The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” is a medium that dynamically holds a program for a short time, such as a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line, In such a case, a volatile memory inside a computer system serving as a server or a client may be included and a program that holds a program for a certain period of time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  Further, a part or all of the POS register 20 in the above-described embodiment may be realized as an integrated circuit such as an LSI (Large Scale Integration). Each functional block of a part of the POS register 20 may be individually made into a processor, or part or all may be integrated into a processor. Further, the method of circuit integration is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor. Further, in the case where an integrated circuit technology that replaces LSI appears due to progress in semiconductor technology, an integrated circuit based on the technology may be used.

  As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to

  In the above embodiment, when the store clerk once leaves the POS register 20 and the other store clerk's ID information (identification information) is read, the operation by the store clerk who has been operating until just before is closed, Although an example in which the opening process is performed based on the read clerk's ID information (identification information) is shown, when the new clerk's ID information (identification information) is read, the POS register 20 displays the first display unit 205, for example. In addition, a message such as “Do you want to open with a new clerk?” May be displayed. In addition, the POS register 20 causes the first display unit 205 to display the keys “Yes” and “No” selected by the store clerk in response to “Do you want to open with a new store clerk?” Only when “Yes” is selected from the “No” key, as described above, the process by the operation by the store clerk who has been operating immediately before is closed, and the newly read store clerk ID information ( The open processing may be performed based on the identification information. As a result, the POS register 20 can prevent an open operation from being accidentally performed by a store clerk located near the POS register 20 due to other tasks.

Further, in normal operation, it is considered that the store clerk moves within a certain range from the device (POS register 20) to work, so that the reading unit 208 and the store clerk possess it even though the store clerk is operating. It is conceivable that the ID information (identification information) to be communicated becomes non-communication. Therefore, since the operation is not permitted due to the non-communication for a short period of time, it is difficult to withstand the operation. Therefore, the time until the communication becomes possible after the non-communication is once set is preset. If the non-communication time is within the set time, the operation of the same clerk may be allowed continuously. If the same ID information (identification information) is not read even after the set time has elapsed, the POS register 20 automatically closes the ID information (identification information). As a result, it becomes possible for the next new store clerk to perform an open process and perform operations such as product registration.
[Appendix]
The present invention can also provide a sales data processing apparatus that can correctly grasp the operation of the store clerk without imposing a burden on the store clerk.
(Additional remark 1) One aspect of the present invention is a sales data processing device for registering product information of a product to be purchased. Reading means for reading identification information for identifying a store clerk stored in a non-contact IC; And a control means for storing information relating to the operation of the store clerk in a storage means in association with each other.
According to this configuration, if the store clerk is located within a certain range with respect to the device, the store clerk's ID information (identification information) stored in the non-contact IC is read. There is no need for special operations or troublesome operations such as manually inputting ID information or reading a barcode encoded ID information. Further, according to this configuration, since the ID information for each clerk and the information related to the operation of the clerk are stored in association with each other, it is possible to correctly grasp the operation of the clerk without imposing a burden on the clerk.
(Additional remark 2) Moreover, the one aspect | mode of this invention is characterized by the information regarding the operation of returned goods, correction | amendment, or cancellation being included in the information regarding the said store clerk's operation.
According to this configuration, the store data processing device stores the ID (identification information) information of the store clerk and the information related to the irregular operation such as the return, correction, or cancel operation of the store clerk. It is possible to correctly grasp a store clerk who has performed an irregular operation such as a return, correction, or cancellation operation (an operation that leads to fraud).
(Supplementary Note 3) Further, according to one aspect of the present invention, the control unit may be configured such that, after the reading unit reads the first identification information as the identification information, the device can be operated with the identification information. When the first identification information is read again, the open state with the first identification information read again is continued.
According to this configuration, when the ID information (identification information) once read is read again during the opening with the identification information, the open state by the ID information is continued, and the sales data processing device once reads While the ID information is being continuously read, it is possible to continue the processing being performed assuming that the same store clerk is operating.
(Additional remark 4) Moreover, 1 aspect of this invention WHEREIN: When the said control means cannot read the said 1st identification information once read by the said reading means, the said operation is disallowed.
According to this configuration, when the ID information (identification information) once read cannot be read, that is, when the clerk who is operating is absent, the operation on the sales data processing device is not permitted. When the store clerk who was operating is absent, the processing device can prohibit the operation of a person other than the store clerk. Therefore, since the sales data processing apparatus is not operated by another person while the salesclerk who was operating is absent, it is possible to correctly grasp the operated salesclerk.
(Supplementary Note 5) Further, according to one aspect of the present invention, in the control unit, when the first identification information once read by the reading unit cannot be read, the first identification information is read again. The operation is permitted.
According to this configuration, when the clerk returns after the clerk who was operating is absent, the clerk is allowed to perform a special operation or troublesome operation because the operation to the sales data processing device is permitted. The operation can be resumed. When the sales data processing device allows the operation to continue when the identification information once read cannot be read and then read again, a predetermined time after the reading cannot be read is set in advance. If it is within, continuous operation may be allowed. Thereby, for example, when a certain time has elapsed, an operation by another store clerk can be permitted.
(Appendix 6) Further, according to one aspect of the present invention, in the control unit, a second identification different from the first identification information after the reading unit cannot read the first identification information once read. When information is read, it has a judging means for judging whether or not to permit the operation.
According to this configuration, when another clerk comes after the clerk who was operating is absent, that is, when the second identification information is read, it is determined whether or not the operation of the clerk is permitted. To do. For example, in the sales data processing device, when the store clerk who was operating before performing the closing process leaves the device and becomes non-communication, the identification information of the store clerk that enables the operation thereafter is set in advance. Only the set clerk may be allowed to continue the operation. For example, if a sales clerk is operating a store clerk who leaves the device while a customer's product is being registered and an alternate store clerk continues to operate it, only a person with certain authority, such as a store manager, You may enable it to operate on behalf of a store clerk. Further, the sales data processing device may update (change) the ID information of the store clerk who operates by using the selection that the operation is permitted as a trigger when another store clerk replaces the operation. Or, if a store clerk changes during one transaction as described above, it is assumed that the transaction that had been changed was processed by the store clerk before the change, and instead a limited store clerk such as the store manager as described above However, the operation from the middle may be allowed as described above.
(Supplementary Note 7) Further, according to one aspect of the present invention, in the case where a predetermined time has elapsed since the control unit cannot read the first identification information once read by the reading unit, the determination unit The operation is permitted in response to reading the second identification information without judging by the above.
According to this configuration, when the ID information once read cannot be read for a preset time or more, that is, when the operated clerk is absent for a preset time or more, the original clerk is replaced. Since there is a high probability of being operated by a new store clerk after that, even if the store clerk who has been operating is absent for a long time, the operation can be quickly performed by another store clerk.
(Appendix 8) Further, according to one aspect of the present invention, in the control unit, when the reading unit reads a plurality of the identification information, any one of the plurality of the identification information read can be selected. And
According to this configuration, when a plurality of ID information (identification information) is read, that is, when a plurality of salesclerks are at the cash register, it is possible to select a salesclerk to operate among the plurality of salesclerks. It becomes possible to select.
