Description

  The present invention relates to a cash register system for storing transaction performance data indicating the contents of a sales transaction, which is used for a sales transaction.

  In sales transactions of retail stores such as supermarkets and convenience stores, a cash register system called a POS system is used. In the cash register system, for each sales transaction, settlement processing such as calculation of a transaction price of a product to be purchased by a customer and settlement of a sales transaction based on the transaction price is performed.

  Further, in the cash register system, data indicating the contents (product name, price, etc.) of each sales transaction obtained in such a settlement process is recorded as transaction result data. With this transaction record data, it is possible to grasp what kind of transaction transaction has been made after the fact.

  As prior art documents disclosing techniques related to the present invention, there are the following documents.

Japanese Examined Patent Publication No. 7-43791

  By the way, in the cash register system, there is known an operation mode provided with a practice mode for practice in addition to a registration mode for performing a normal operation. The practice mode is an operation mode for practice of operating the cash register system, and the same operation as the registration mode is possible, such as reading the product code of the product. However, in the practice mode, even if the same operation as the checkout process is performed, it is not based on an actual sales transaction, and therefore the contents of the transaction result data are not updated with the data obtained by the operation.

  By misusing the feature of practice mode such that the contents of transaction result data are not updated, the fraud of stealing sales that are not recorded in the transaction result data by setting the operation mode to practice mode during business hours of the store, Sometimes done by store sales staff. However, since the same operation as that in the registration mode can be performed in the practice mode, it is difficult to immediately determine whether or not such fraud has been made from the operation of the sales staff.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a cash register system that can easily determine the operation mode at that time from the vicinity.

  In order to solve the above-mentioned problems, the invention of claim 1 is a cash register system used for sales transactions, the storage means storing transaction result data indicating the contents of the sales transactions, and the transaction results based on user operations. Switching means for switching between an operation mode including a registration mode for updating data contents and a non-registration mode for not updating the transaction record data contents regardless of a user operation, and an operation sound in response to the user operation And an output unit, and a control unit that varies the output mode of the operation sound by the output unit between the registration mode and the non-registration mode.

  The invention of claim 2 further comprises reading means for reading product information associated with a product in the cash register system according to claim 1, wherein the operation sound causes the reading means to read the product information. The reading sound in response to this is included.

  According to a third aspect of the present invention, in the cash register system according to the first or second aspect, in the non-registration mode, the control unit varies the output mode between consecutive operation sounds.

  According to a fourth aspect of the present invention, in the cash register system according to the first or second aspect, in the non-registration mode, the control means forms a predetermined melody with a plurality of continuous operation sounds.

  The invention according to claim 5 is the cash register system according to any one of claims 1 to 4, wherein the operation sound is a beep sound, and the output mode is a volume, a pitch, and a sound length. Including at least one of length and number of sounds.

  The invention according to claim 6 is the cash register system according to claim 1 or 2, wherein the control means outputs a beep sound as the operation sound in the registration mode and as the operation sound in the non-registration mode. The language sound is output.

  According to the first to fifth aspects of the present invention, since the output mode of the operation sound is different between the registration mode and the non-registration mode, a nearby listener can easily determine which operation mode at that time is based on the operation sound. I can judge.

  In particular, according to the invention of claim 2, since an operation sound is generated every time the product information is read, the operation sound is generated relatively frequently, so that it is easy to determine which operation mode the listener is in. it can.

  In particular, according to the invention of claim 3, since the output mode of the operation sound is changed for each user operation in the non-registration mode, the listener is strongly given an impression different from that in the registration mode. Thereby, the listener can easily determine that the mode is the non-registration mode.

  In particular, according to the fourth aspect of the present invention, since the predetermined melody is formed by a plurality of continuous operation sounds in the non-registration mode, a strong impression different from that in the registration mode is given to the listener. Thereby, the listener can easily determine that the mode is the non-registration mode.

  In particular, according to the invention of claim 5, it is easy to change the output mode of the operation sound.

  In particular, according to the invention of claim 6, since the language sound is output as the operation sound in the non-registration mode, the listener is strongly given an impression different from the registration mode. Thereby, the listener can easily determine that the mode is the non-registration mode.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1. First Embodiment>
<1-1. Configuration>
FIG. 1 is a diagram showing a configuration of a POS system 100 that is a cash register system according to the first embodiment. The POS system 100 is employed in a store such as a supermarket or a convenience store, and includes a POS server 1 and a plurality of POS terminals 2. The POS server 1 and the POS terminal 2 are each connected to the LAN 3 and can communicate with each other.

  The POS server 1 controls the entire POS system 100 in an integrated manner, and is usually arranged in a management office or the like different from the store sales area. On the other hand, the POS terminal 2 is arranged in the sales area of the store, and is actually operated by the sales staff of the store in the case of merchandise sales transactions. Specifically, the POS terminal 2 is used for settlement processing for deriving a transaction price used for settlement of a sales transaction, settlement of the sales transaction, and the like.

  FIG. 2 is a functional block diagram showing the configuration of the POS server 1. The POS server 1 has the same hardware configuration as a general computer. That is, the POS server 1 has a configuration in which a CPU 11 that performs arithmetic processing, a ROM 12 that stores basic programs, a RAM 13 that is a work area for arithmetic processing, and a hard disk 14 that stores various data are connected to the bus line 10. ing. The POS server 1 further includes a display 15 that displays various information, an input unit 16 such as a keyboard and a mouse, and a communication unit 17 that communicates via the LAN 3, which are connected to the bus line 10. The

  A processing program is stored in the hard disk 14, and various functions as the POS server 1 are realized by the CPU 11 performing arithmetic processing according to the processing program. The hard disk 14 further stores a product master 41 indicating information on each product, transaction result data 42 indicating the contents of each sales transaction, and the like.

  The product master 41 is data in a table format indicating various information about each product handled at the store. The merchandise master 41 is used by the POS terminal 2 to acquire “product name” and “price” of the merchandise in the checkout process. The product master 41 includes a plurality of records. In each record, information such as “product name” and “price” is associated with “product code” which is an identification code for identifying a product. .

  The transaction record data 42 is data indicating specific contents of past sales transactions. In the transaction record data 42, data such as “transaction time” regarding each sales transaction and “product name” and “price” of the product targeted for the transaction are registered. The data of each sales transaction is acquired by the POS terminal 2 during the settlement process, transmitted to the POS server 1 and registered in the transaction result data 42.

  FIG. 3 is a diagram showing the configuration of the POS terminal 2 in functional blocks. The POS terminal 2 reads a bar code, a control unit 21 for controlling the entire apparatus, two displays 22 and 23 for displaying various information, an input unit 24 having various buttons for receiving user operations and inputs, and the like. A bar code reader 25, a print issuing unit 26 that prints and issues a receipt, a communication unit 27 that communicates via the LAN 3, and a speaker 29 that outputs an operation sound in response to a user operation. These are respectively connected to the bus line 20.

  The control unit 21 includes a CPU 201 that performs various arithmetic processes, a ROM 202 that stores a control program, a RAM 203 that is a work area for arithmetic processes, a battery-backed SRAM 204 that is a nonvolatile memory that stores various data, And a timer 205 for measuring time such as transaction time. The control function of each part of the apparatus and the data processing function for the settlement process are realized by the CPU 201 performing arithmetic processing according to the control program in the ROM 202.

  Of the two displays 22 and 23, one display 22 is a sales-side display 22 that displays information to be displayed on the side of a sales staff member who performs an operation, and the other display 23 should be displayed on the customer side. It is the customer side display 23 which displays information. The screen of the sales-side display 22 is composed of a dot matrix type liquid crystal having a touch panel function, and various types of information such as characters, figures and images can be displayed in color, and user operations can be accepted. Yes. On the other hand, the screen of the customer-side display 23 is composed of a relatively simple VFD (fluorescent display tube), and can only display a single line of character strings in two lines. The orientation of the screen of the customer-side display 23 is adjusted so that the customer can easily see in the checkout process.

  Further, the input unit 24 includes a mode changeover switch for switching the operation mode of the POS terminal 2 together with various buttons such as a subtotal key and a numeric keypad for instructing subtotal processing in the settlement processing. The POS terminal 2 includes a “registration mode” for performing a normal operation such as a checkout process, and a “practice mode” for practice of operation as its operation mode. Such an operation mode can be switched by operating the mode switch.

  In the “registration mode”, data obtained in the settlement process is transmitted to the POS server 1 and reflected in the contents of the transaction result data 42. On the other hand, in the “practice mode”, it is possible to perform the same operation as in the registration mode, but even if the same operation as the checkout process is performed, the data obtained thereby is not transmitted to the POS server 1. It is not reflected in the contents of the transaction result data 42. That is, it can be said that the “registration mode” is an operation mode in which the contents of the transaction record data 42 are updated based on the user operation, and the “practice mode” is an operation mode in which the contents of the transaction record data 42 are not updated regardless of the user operation ( It can be said that this is a non-registration mode.

  For example, the barcode reader 25 is a portable reader that can be held by hand. The barcode reader 25 reads a barcode indicating a product code attached to the product by printing or a label, and acquires the product code of the product. When the barcode reader 25 normally reads the barcode of the product, in response to this, a scanning sound (reading sound) is output from the speaker 29 under the control of the control unit 21. For example, the scan sound is a beep sound. With this scan sound, the sales staff who has made the barcode reader 25 read the product barcode can recognize that the product barcode has been read normally.

<1-2. Scan sound settings>
The POS terminal 2 outputs different scan sounds depending on the operation mode. For this reason, the sound setting processing for setting the scan sound to be output is performed by the control unit 21 at the time of start-up and when the operation mode is changed by operating the mode switch.

  FIG. 4 is a diagram showing the flow of the sound setting process. First, the operation mode at that time is confirmed (step S11). If the operation mode is “registration mode”, a normal scan sound (hereinafter referred to as “normal scan sound”) is set as a scan sound to be output in the subsequent processing (step S12). On the other hand, if the operation mode is “practice mode”, a scan sound for practice (hereinafter referred to as “practice scan sound”) different from the normal scan sound is set as a scan sound to be output in the subsequent processing. (Step S13).

  Thereafter, the POS terminal 2 outputs a normal scan sound in the “registration mode” and a practice scan sound in the “practice mode”. The normal scan sound and the practice scan sound differ in at least one of “volume”, “pitch”, “sound length”, and “number of sounds”. For this reason, the output mode of the scan sound is changed between the “registration mode” and the “practice mode”. In order to make it easy to distinguish between normal scan sound and practice scan sound, preferably, normal scan sound and practice scan sound are “volume”, “pitch”, “sound length” and “sound It is desirable that two or more of the numbers are different.

  As a specific example of changing the “volume”, for example, the volume of the practice scan sound is made larger than the volume of the normal scan sound. Further, as a specific example of making the “pitch” different, for example, the normal scan sound is a sound of 880 Hz (“La” sound) and the practice scan sound is a sound of 523 Hz lower than that (“Do”), for example. Sound). It can be expressed that “sound pitch” is different from “sound frequency”.

  Further, as a specific example in which the “sound length” is made different, for example, the normal scan sound has a length of 0.1 seconds called “beep” and the practice scan sound has a length of 0.5 seconds called “beep”. And so on. Further, as a specific example in which the “number of sounds” is made different, for example, the normal scan sound is one sound “beep” and the practice scan sound is two sounds “beep”.

<1-3. Operation in registration mode>
Next, the flow of the settlement process in the “registration mode” of the POS terminal 2 will be specifically described. FIG. 5 is a diagram showing the flow of the settlement process. The series of processing shown in FIG. 5 is processing performed for each sales transaction (for each product group that one customer desires to purchase).

  First, the POS terminal 2 is in a state of waiting for reading of the barcode of the product by the barcode reader 25. In this state, the sales staff performs an operation of causing the barcode reader 25 to read the barcode attached to one product in the product group that the customer desires to purchase (step S21).

  When the barcode is normally read by this operation, the product code of the product indicated by the barcode is acquired by the POS terminal 2. In response to this, a scanning sound is output from the speaker 29 under the control of the control unit 21. Since this is the “registration mode” in this case, this scan sound is a normal scan sound (step S22).

  Next, the acquired product code is transmitted from the POS terminal 2 to the POS server 1. In response to this, the POS server 1 searches the merchandise master 41 for a record including the merchandise code, and returns the contents of the corresponding record to the POS terminal 2. Thereby, product data such as “product name” and “price” of the product is acquired in the POS terminal 2 (step S23).

  Subsequently, when the barcode related to the next product is read (Yes in step S24), the normal scan sound is output in the same manner as described above (step S22), and the product data of the product is acquired. (Step S23). Such a process is similarly repeated for all products that the customer desires to purchase. Therefore, every time the barcode of the product is read, the normal scan sound is output and the product data of the product is acquired. When the barcodes of all the products are read, the product data of all the products is acquired by the POS terminal 2.

  When reading of the barcodes of all the products is completed, the sales staff presses the subtotal key included in the input unit 24. When the subtotal key is pressed (Yes in step S25), the CPU 201 derives the total product price obtained by adding up the “price” for all the acquired products. The derived total product price is displayed on the sales-side display 22 and the customer-side display 23 as a transaction price that is an amount to be paid by the customer (step S26).

  Next, settlement processing is performed based on the transaction price. That is, an amount of cash for settlement delivered from the customer is input as a deposit amount via the input unit 24, and a result obtained by subtracting the transaction price from the deposit amount is derived as a change amount, and the change amount is displayed. 22 and 23. Thereby, the settlement processing of this sales transaction is completed (step S27).

  Next, a receipt indicating the contents of this sales transaction is issued by the print issuing unit 26 (step S28). Further, the data indicating the contents of the sales transaction (transaction time, product name, price, transaction price, change amount, etc.) obtained by the above processing is transmitted to the POS server 1. In response to the reception of this data, the POS server 1 records the received data as part of the contents of the transaction record data 42, and updates the contents of the transaction record data 42 (step S29). As a result, a series of payment processing ends.

<1-4. Operation in practice mode>
Next, the operation of the POS terminal 2 in the “practice mode” will be described. Also in the “practice mode”, it is possible to cause the POS terminal 2 to perform substantially the same processing as the settlement processing by performing a similar operation as in the “registration mode” assuming a trading transaction. The pseudo process similar to the settlement process in the “practice mode” is hereinafter referred to as “pseudo settlement process”. FIG. 6 is a diagram showing the flow of the pseudo settlement process.

  First, the POS terminal 2 is in a state of waiting for reading a barcode of a product (step S31). In this state, when the sales staff performs an operation of causing the barcode reader 25 to read the barcode attached to one product, the product code of the product is acquired by the POS terminal 2.

  In response to this reading, a scanning sound is output from the speaker 29 under the control of the control unit 21. In this case, since it is the “practice mode”, this scan sound becomes a practice scan sound (step S32). Next, product data is acquired from the POS server 1 based on the acquired product code (step S33).

  Subsequently, when the barcode related to the next product is read (Yes in step S34), the practice scan sound is output in the same manner as described above (step S32), and the product data of the product is acquired. (Step S33). Thereafter, every time the barcode of the product is read, a practice scan sound is output and product data of the product is acquired.

  As described above, since the practice scan sound different from the normal scan sound is output every time the barcode of the product is read, the practice scan sound is frequently output. Therefore, a nearby listener can easily determine that the operation mode of the POS terminal 2 at that time is an operation mode different from the normal “registration mode” (ie, “practice mode”) based on the scan sound. It is possible to recognize.

  When the subtotal key is pressed after reading the barcode of the product (Yes in step S35), the total product price is derived by the CPU 201, and the total product price is displayed on the sales side display 22 and the customer side display 23. (Step S36). Next, a pseudo settlement process is performed based on the total product price. That is, a provisional deposit amount is input via the input unit 24, a result of subtracting the total product price from the provisional deposit amount is derived as a change amount, and the change amount is displayed on the displays 22 and 23 ( Step S37).

  Next, a receipt indicating the contents of the pseudo sales transaction is issued by the print issuing unit 26 (step S38). As a result, a series of pseudo settlement processing is completed. Since such a “practice mode” pseudo-settlement process is assumed to be a pseudo trading transaction, data obtained by the process is not transmitted to the POS server 1. Therefore, the contents of the transaction record data 42 are not updated.

  As described above, the POS terminal 2 has, as operation modes, “registration mode” for updating the contents of transaction record data based on a user operation, and “practice mode” for not updating the contents of transaction record data regardless of the user operation. ". The “registration mode” and the “practice mode” differ in the output form of the scan sound that is output in response to reading the barcode of the product. Therefore, a nearby listener can easily determine whether the operation mode of the POS terminal 2 at that time is “registration mode” or “practice mode” based on the scan sound. For this reason, when a certain store staff sets the operation mode to “practice mode” during the business hours of the store, other store staff in the vicinity can immediately recognize that fact. As a result, it is possible to effectively prevent fraud that exploits the feature of the “practice mode” that the contents of the transaction record data 42 are not updated.

<2. Second Embodiment>
Next, a second embodiment will be described. The configuration of the POS system 100 according to the second embodiment and the flow of the adjustment process in the “registration mode” are the same as those in the first embodiment. A scan sound is output. However, the flow of the pseudo adjustment process in the “practice mode” of the POS system 100 of the second embodiment is different from that of the first embodiment. In the “practice mode” pseudo checkout process, a predetermined practice scan sound is output in the first embodiment, but in the second embodiment, the “pitch” is changed every time the scan sound is output. As a result, a predetermined melody is formed by a plurality of consecutive scan sounds.

  Therefore, the melody data indicating the melody information is stored in the SRAM 204 of the POS terminal 2. The melody data indicates the order of a plurality of sounds that form a melody (that is, a series of consecutive sounds whose pitches change) and the pitch of the sounds. For example, if the melody to be formed is an Italian note name "De les mi fa fa mi les de", "de" "les" "mi" "fa" "mi" "les" Seven pitches corresponding to “do” are described in the melody data in this order.

  FIG. 7 is a diagram illustrating a flow of the pseudo adjustment process in the “practice mode” according to the second embodiment. First, the melody data is read from the SRAM 204, and the order of a plurality of sounds constituting the melody and the respective pitches are recognized by the control unit 21 (step S41).

  Next, the POS terminal 2 enters a state where it waits for reading of the barcode of the product (step S42). In this state, when the sales staff performs an operation of causing the barcode reader 25 to read the barcode attached to one product, the product code of the product is acquired by the POS terminal 2.

  In response to this reading, a scanning sound is output from the speaker 29 under the control of the control unit 21. At this time, the first one of the plurality of sounds indicated by the melody data is output as a scan sound (step S43). For example, as in the above example, if the melody to be formed is “DO LE MI FA FA MI LE DO”, the first “DO” is output as the scan sound. Next, product data is acquired from the POS server 1 based on the acquired product code (step S44).

  Subsequently, when the barcode related to the next product is read (Yes in step S45), the control unit 21 controls the next sound following the previously output sound among the plurality of sounds indicated by the melody data. One sound is output as the scan sound. For example, if the melody to be formed as in the above example is “do les mi fa mi les de”, the “s” next to the first “do” is output as the scan sound (step S46). Subsequently, product data of the product is acquired (step S44).

  Thereafter, every time the barcode of the product is read, the next sound following the sound output most recently among the plurality of sounds indicated by the melody data is output as a scan sound (step S46). Therefore, if the barcodes of a plurality of products are read, a plurality of sounds indicated by the melody data are sequentially output, and a plurality of continuous scan sounds form a predetermined melody. When the most recently output scan sound is the last sound indicated by the melody data, the first sound indicated by the melody data may be output as the next scan sound. Thereby, a predetermined melody is repeated.

  When the subtotal key is pressed after reading the barcode of the product (Yes in step S47), the same processing as in the first embodiment (the processing after step S36 in FIG. 5) is performed thereafter.

  As described above, in the POS terminal 2 according to the second embodiment, in the “practice mode” pseudo checkout process, the pitches of the continuous scan sounds are different from each other, and a predetermined melody is generated by a plurality of continuous operation sounds. Is supposed to form. Since such a melody remains in the ear, the impression that the scan sound in the “practice mode” is different from the normal scan sound in the “registration mode” is strongly given to the listener. As a result, the listener can more easily determine whether the operation mode of the POS terminal 2 at that time is “registration mode” or “practice mode” based on the scan sound.

  Even if some of the sounds that make up the melody are the same as the normal scan sound in “Registration Mode”, the other sounds that make up the melody are different from the normal scan sound, and the melody impression is strong. Therefore, the effect is not reduced.

  In the second embodiment, the melody is formed by the scan sound. However, even when the “pitch” is simply made different between the continuous scan sounds without forming the melody. , Give listeners a great sense of incongruity. For this reason, even in this case, the listener can be given a strong impression that it is different from the normal scan sound, and the listener can easily determine the operation mode. In addition, other output modes such as “volume”, “sound length”, and “number of sounds” may be different between consecutive scan sounds.

<3. Other embodiments>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible. Hereinafter, such other embodiments will be described. Of course, you may combine the form demonstrated below suitably.

  In the above embodiment, the scan sound is described as a beep sound whose output mode can be easily changed. However, in the “registration mode”, the scan sound of the beep sound is output, whereas in the “practice mode”, the beep sound is not. You may make it output the linguistic sound comprised in the language which a human can recognize as a scanning sound. For example, in the “practice mode”, a speech sound “renshuchu (under practice)” can be output as a scan sound. Even in such a case, it can be said that the scan sound output mode is different between the “practice mode” and the “registration mode”.

  In the above embodiment, the description has been made assuming that the output mode of the scan sound is different between the “registration mode” and the “practice mode”, but the output mode of the operation sound other than the scan sound may be different. . For example, a button sound in response to pressing a button included in the input unit 24, a click sound in response to touching the screen of the sales-side display 22 as a touch panel, and the like in “registration mode” and “practice mode” It may be changed.

  In addition, although only the “practice mode” has been described as the non-registration mode in which the contents of the transaction record data 42 are not updated regardless of the user operation, of course, other operation modes may exist as such a non-registration mode. As the non-registration mode, for example, a “price reference mode” that is an operation mode in which product data such as “price” is simply displayed in response to reading of a barcode of the product can be considered.

  In the above embodiment, the POS terminal 2 has been described as including the portable barcode reader 25. However, as shown in FIG. 8, a scanner that reads a barcode as a device separate from the POS terminal 2. A device 5 may be provided. The scanner device 5 includes an operation panel 51, a barcode reader 52, and a speaker 53, and outputs a scanning sound from the speaker 53 in response to reading of the barcode by the barcode reader 52. The scanner device 5 is electrically connected to the POS terminal 2, and the product code obtained by reading the bar code is transmitted to the POS terminal 2, and its operation is controlled by the control unit 21 of the POS terminal 2. The In this case, when the operation mode of the POS terminal 2 is switched, the output mode of the scan sound output from the scanner device 5 is changed under the control of the control unit 21 of the POS terminal 2.

  In the above embodiment, the cash register system has been described as the POS system 100 including the POS server 1 and the plurality of POS terminals 2. However, even if the cash register system is configured as a single device, The technique described above can be suitably applied.

  Further, in the above embodiment, the description has been made on the assumption that the scanning sound is output when the barcode of the product is read. However, the two-dimensional barcode such as a QR code attached to the product, the RFID attached to the product, etc. The information recorded on the recording medium may be read, and a reading sound may be output when product information such as a product code is normally acquired.

  In the second embodiment, the predetermined melody is formed by a plurality of continuous scan sounds in the “practice mode”. However, the scan sound output at a time may be a melody. . Even in such a case, it can be said that the scan sound output mode is different between the “practice mode” and the “registration mode”.

  In the above embodiment, the operation mode switching is not limited. However, the operation mode switching itself may be limited by the control of the control unit 21 or the like. For example, the operation mode cannot be changed to the “practice mode” during the predetermined business hours based on the time obtained from the timer 205, or the input of a predetermined password is required to set the operation mode to the “practice mode”. You may make it. According to this, since it becomes difficult to set the operation mode to “practice mode (non-registration mode)”, fraud can be effectively prevented.

  Alternatively, all user operations at the POS terminal 2 may be monitored by the control unit 21, and an operation log indicating the contents of all user operations may be recorded in the SRAM 204, the hard disk 14 of the POS server 1, or the like. According to this, since it is possible to grasp afterwards that the operation mode has been changed to the “practice mode” during business hours, it is possible to specify that there has been fraud in the past.
