Description

  The present invention relates to a self-registering device in which a customer registers a product himself.

  There has already been proposed a self-registering device in which a customer registers a product by operating a cash registering device (money registering machine) himself at a store.

When an error occurs in such a self-registering device, a self-registering device provided with a lamp for notifying the state in which the error has occurred has been proposed as a technique for notifying the store clerk of the error ( Patent Document 1). When such a self-register device detects that a problem has occurred in its own device, it notifies the store clerk of the problem by turning on the lamp. In addition, a technology has been proposed that is configured to be communicable with a self-register device, and separately provides a monitoring terminal for monitoring the operation status of the self-register device through communication and displaying the fact when a problem occurs. (See Patent Document 2). Thereby, the store clerk can confirm the problem which arose in the self-register apparatus by seeing the monitoring terminal in the position away from the self-register apparatus.
JP 2007-072561 A Japanese Patent Laid-Open No. 09-120484

  By using the apparatus described in Patent Document 1, the store clerk can know that a problem has occurred by lighting the lamp. However, in order to determine what kind of problem has occurred, the store clerk moves to the purchaser side and displays the error content displayed on the display unit directed to the purchaser side of the self-register device. I had to see it. For this reason, the store clerk who knows that the problem has occurred cannot move to addressing the problem immediately without knowing the content of the error unless he / she has moved to the place of the purchaser. Therefore, it has been difficult to realize a quick restoration process by the store clerk. In addition, when the device described in Patent Document 2 is used, the contents of the error can be understood, but it is necessary to separately provide a monitoring terminal in addition to the self-register device itself, which requires installation space and a large cost. There was a problem.

  SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a self-register device that enables quick problem processing by a store clerk quickly grasping the contents of a problem that has occurred in the self-register device. .

  A first aspect of the present invention is a self-register device in which a purchaser of a product identifies a product, reads product information such as a product name and price, and registers the product, and reads out to a purchaser who operates the device. First display means for displaying the merchandise information displayed, second display means facing in a direction different from the first display means that the store clerk can visually recognize, and error information indicating the problem for each problem occurring in the device itself And a control unit for reading out error information corresponding to the generated problem from the storage unit and displaying the read error information on the second display unit when a problem occurs in the own device. Means.

  According to the first aspect of the present invention configured as described above, the clerk or the like does not bother to move to the place where the purchaser is and confirm the second display unit without confirming the first display unit. It is possible to grasp the error contents. Therefore, it is possible to save the labor of a store clerk and the like, and it is possible to quickly grasp the contents of a problem that has occurred in the self-register device and perform processing.

  In the first aspect of the present invention, the different direction may be a direction substantially opposite to the direction of the first display means.

  With this configuration, it is possible to notify error information to a salesclerk or the like in a substantially opposite direction. That is, it becomes possible for a store clerk or the like in a substantially opposite direction to check the error information on the spot.

  In the first aspect of the present invention, the control means is configured to cause the second display means to display information relating to the product information read when the product is specified when it is not determined that a problem has occurred. Also good.

  With this configuration, when no problem occurs, information on the registered product is displayed on the second display means, so which product is registered or how many products are Since the store clerk can grasp on the spot whether it is registered or the like, it is easy to monitor unauthorized product registration.

  In the first aspect of the present invention, when a problem occurs in the own device, the control means causes the first display means to display a display prompting an operation that can be performed only by a store clerk for displaying the content of the problem that has occurred. It may be configured to have a receiving unit for the operation and to control the error information to be displayed on the first display unit by receiving the receiving unit.

  With this configuration, when an error occurs, the purchaser knows where the problem is, in particular, until a store clerk who knows the operation for displaying the content of the problem that has occurred performs the operation. Absent. For this reason, it is possible to prevent the purchaser from touching the self-register device without causing any further problems.

  The second aspect of the present invention is a self-register device that is arranged in a face-to-face counter that performs product check-out in a store or the like, and a product purchaser specifies a product, reads product information such as a product name and price, and performs a product registration operation The first display means for displaying the read product information to the purchaser who operates the device, facing the one side across the counter, and the second facing the other side across the counter Display means, storage means for storing a judgment criterion for a problem occurring in the own apparatus and error information indicating the problem in association with each other, and if it is determined that a problem has occurred in the own apparatus, the problem that occurred Control means for reading out the error information to be read from the storage means and controlling the read error information to be displayed on the second display means.

  With such a configuration, it is possible to notify error information to a clerk on the other side across the counter. Therefore, the store clerk can grasp the error that has occurred before moving to the front of the first display unit, so that it is possible to take a quick error measure.

  According to the present invention, it is possible for a store clerk to quickly grasp the contents of a problem that has occurred in the self-register device and process it with a simple configuration.

  FIG. 1 is a diagram showing the appearance of the self-register device 1. FIG. 2 is a block diagram showing a configuration of the self-register device 1. The self-register device 1 includes a CPU (Central Processing Unit) 10 (control means), a hard disk unit 11, a RAM (Random Access Memory) 12, a first display unit 13 (first display unit), and a second display unit 14 (second display). Display means), a speaker unit 15, a receipt printing unit 16, a scanner unit 17, and a reader / writer unit 18. Among these, the 1st display part 13, the 2nd display part 14, the speaker part 15, the receipt printing part 16, and the reader / writer part 18 appear in the external appearance.

  The CPU 10 executes various calculations and controls each part of the self-register device 1 based on the calculation results. Further, when a problem occurs in the self-register device 1, the CPU 10 detects the occurrence of the problem and determines the error content. The problem that may occur in the self-register device 1 is, for example, that the product corresponding to the barcode read by the scanner unit 17 is not in the product table (in other words, there is no PLU (Price Look Up): error code) (Corresponding to “0001”), the printer in the receipt printing unit 16 is not ready (corresponding to the error code “0002”), or the receipt paper set in the receipt printing unit 16 has been broken ( The product corresponding to the error code “0003” or the barcode read by the scanner unit 17 exists in the product table, but the price is set to 0 yen (the error code “0004”) The balance amount in the electronic money recording medium set in the reader / writer 18 Insufficient with respect to the total amount (error code “0005”), etc., which are preset in the error code table.

  When the CPU 10 obtains a product code from the barcode read by the scanner unit 17 and searches the product table using this product code as a key, there is a problem that there is no PLU if there is no corresponding product code. Detect that. Further, when the receipt print unit 16 cannot receive a ready signal from the printer, the CPU 10 detects that a problem that the printer is not ready has occurred. Further, when the CPU 10 receives a signal indicating that the sheet is out of paper from the receipt printing unit 16, the CPU 10 detects that a problem has occurred that the receipt sheet has been broken. Further, when the CPU 10 obtains a product code from the barcode read by the scanner unit 17 and searches the product table using the product code as a key, the value of the price associated with the product code is “0”. If it is, it is detected that the problem that the selling price is 0 has occurred. In the accounting process, the CPU 10 detects that a problem of insufficient balance has occurred when the balance amount in the electronic money recording medium is smaller than the total amount of purchased products. When the CPU 10 detects a problem in this manner, the CPU 10 acquires an error code (error information) corresponding to the problem from the error table and displays it on the second display unit 14.

  The hard disk unit 11 is a readable / writable large-capacity storage device. The hard disk unit 11 stores a program for realizing each function of the self-register device 1. The hard disk unit 11 stores a product table. FIG. 3 is a diagram illustrating the contents of the product table. The product table has data such as a product code, a product name, and a price (unit price) associated with each product handled in the store where the self-register device 1 is installed. The product code corresponds to a value obtained by decoding the barcode data read by the scanner unit 17. The hard disk unit 11 stores an error code table. FIG. 4 shows the contents of the error code table. The error code table has an error code, an error content, a judgment criterion, and a clerk flag in association with each other. The error code is identification information indicating the content of the error, and is represented using, for example, a 4-digit number. The error code may be expressed using other alphabets and symbols, and need not be limited to four digits. The error content indicates the content of the problem that occurred. The determination criterion indicates a determination criterion when the CPU 10 detects the occurrence of a problem. The clerk flag indicates whether or not the clerk flag needs to be called when an error occurs. “1” indicates that it is necessary to call a clerk, and “0” indicates that it is not necessary to call a clerk.

  The RAM 12 is a readable / writable storage device. The RAM 12 stores various data used when the CPU 10 performs processing such as data read by the CPU 10 from the hard disk unit 11. FIG. 5 is a diagram showing an outline of the storage area of the RAM 12. The RAM 12 includes a flag area, a register area, a purchased product code area, a purchased product accumulated amount area, and a purchased product accumulated number area. The flag area is an area for storing a flag for the CPU 10 to operate. The register area is an area that operates as a register. The purchased product code area is an area for storing the product code of each product for which a barcode is input via the scanner unit 17 (hereinafter referred to as “input product”). The purchased product accumulated amount area is an area for accumulating the amount of the input product and storing the accumulated amount. The purchased product accumulated number area is an area for accumulating the number of inputted products and storing the accumulated number.

  The RAM 12 pays when the accounting process is reset (when the “return to first” button is pressed in the first display unit 13) or when the accounting process is completed (the total amount of the input goods is paid by electronic money). In the case where the purchased product code area, the purchased product accumulated price area, and the purchased product accumulated number area are cleared, the stored data is cleared.

  The 1st display part 13 is comprised using image display apparatuses, such as a liquid crystal display and an organic EL (organic ElectroLuminescence) display. The first display unit 13 is configured as a touch panel. FIG. 6 is a diagram illustrating a display example of the first display unit 13. The first display unit 13 displays information necessary for the customer who is the purchaser (operator of the self-register device 1) to perform the accounting process. For example, the first display unit 13 displays product information such as a product name, a price (unit price), and a number for each input product in the order of reading. This display is controlled by the CPU 10 based on data stored in the purchased product code area of the RAM 12. FIG. 6 is a display example when barcodes are read in the order of throat cake, gum, and magazine. The first display unit 13 may display an operation procedure (operation guide) and help for operating the self-register device 1.

  In addition, the first display unit 13 displays the cumulative number of input products as “the number of purchases”. This display is controlled by the CPU 10 based on data stored in the accumulated number of purchased products area of the RAM 12. In addition, the first display unit 13 displays the total value of the input commodity prices as “subtotal” or “total”. This display is controlled by the CPU 10 based on data stored in the purchased product accumulated amount area of the RAM 12. The first display unit 13 displays the balance amount read from the electronic money recording medium by the reader / writer unit 18 as “balance”. This display is controlled by the CPU 10 based on the data of the balance amount read by the reader / writer 18 in the RAM 12.

  In addition, the first display unit 13 displays a “return to start” button and a “checkout” button as buttons on the touch panel. When the “return to start” button is touched by the purchaser, the first display unit 13 transmits to the CPU 10 a signal indicating that the “return to start” button has been pressed. Upon receiving this signal, the CPU 10 changes the display on the first display unit 13 to a display in which no product is input. In response to this signal, the CPU 10 initializes data stored in the purchased product code area, the purchased product accumulated amount area, and the purchased product accumulated number area of the RAM 12. When the “checkout” button is touched by the purchaser, the first display unit 13 transmits a signal indicating that the “checkout” button has been pressed to the CPU 10. In response to this signal, the CPU 10 subtracts the amount stored in the purchased product accumulated amount area from the balance amount read from the electronic money recording medium via the reader / writer 18. Then, the CPU 10 writes the subtraction result as a new balance amount in the electronic money recording medium via the reader / writer 18.

  The first display unit 13 displays an error according to the control of the CPU 10 when a problem occurs in the self-register device 1. FIG. 7 is a diagram illustrating an example of error display on the first display unit 13. When a problem occurs in the self-register device 1, the first display unit 13 displays an error window 131 shown in FIG. 7 in accordance with an instruction from the CPU 10 that has detected the problem. At this time, the error window 131 may be displayed as the previous layer, and the operation screen display shown in FIG. 6 may be displayed as the subsequent layer. The error window 131 includes a display notifying that a problem has occurred and a display prompting the purchaser to call a store clerk. The error window 131 includes a confirmation button 132. When the confirmation button 132 is touched by the purchaser, the first display unit 13 detects this and transmits a signal indicating that the confirmation button 132 has been pressed to the CPU 10. In response to this signal, the CPU 10 displays a corresponding error as shown in FIG. If the problem that has occurred in the self-register device 1 is not solved, the CPU 10 does not accept the operation of the accounting process by the purchaser even if the error window 131 is closed on the first display unit 13.

  The 2nd display part 14 is comprised using the display apparatus of a 7 segment display. As shown in FIG. 1, the second display unit 14 has a display surface in a direction substantially opposite to the display surface of the first display unit 13 (so as to face the back surface of the first display unit 13). FIG. 8 is a diagram illustrating a display example of the second display unit 14. The second display unit 14 displays the number of items and the amount of money that are input via the scanner unit 17 immediately before. In the case of FIG. 8, the second display unit 14 displays that the number of input products is “1” and the amount is “100” yen (information on products). When the barcode of the next product is read by the scanner unit 17, the number and amount of the barcode are added and displayed, and information about the product such as the accumulated number of purchased products and the accumulated amount of purchased products is displayed. The

The second display unit 14 is not limited to a 7-segment display, and may be a display device such as an LED display or a liquid crystal display. Further, the second display unit 14 is not integrated with the main body of the apparatus, and the second display unit 14 is not in the direction substantially opposite to that of the first display unit 13. It may be shifted by about 210. That is, it is only necessary that the salesclerk over the counter can visually recognize the display on the second display unit 14.
In addition, when a problem occurs in the self-register device 1, the second display unit 14 displays an error according to an instruction from the CPU 10 that has detected the problem. FIG. 9 is a diagram illustrating an example of error display on the second display unit 14. When a problem occurs in the self-register device 1, the second display unit 14 displays an error code in accordance with an instruction from the CPU 10 that has detected the problem. When a problem occurs in the self-register device 1, the CPU 10 determines the content of the problem and reads the error code of the corresponding error from the error table. Then, the CPU 10 performs control so that this error code is displayed on the second display unit 14. For example, if the price of the input product is 0 yen in the product table, the CPU 10 detects this and reads the error code “0004” from the error table. Then, as shown in FIG. 9, the second display unit 14 displays the error code “0004” together with the characters “ERROR”. Moreover, when the 2nd display part 14 is comprised as a large sized display part using a liquid crystal display, an LED display, etc., you may display all the goods which the customer registered the goods by transaction in order.

  When the barcode is normally read by the scanner unit 17, the speaker unit 15 emits a sound effect to notify that effect. In addition, when a problem occurs in the self-register device 1, the speaker unit 15 generates an error sound based on the control of the CPU 10 that has detected the problem.

  The receipt printing unit 16 has a printing function. The receipt printing unit 16 prints the details of the purchased product on a predetermined receipt sheet in accordance with an instruction from the CPU 10. The receipt printing unit 16 may perform printing by using ink, or may perform printing by a method that does not use ink, such as thermal paper.

  The scanner unit 17 is configured using a barcode scanner. The scanner unit 17 reads a barcode attached to a product. When the scanner unit 17 reads the barcode, it decodes the read data and transmits it to the CPU 10.

  The reader / writer unit 18 reads the balance amount from the electronic money recording medium located at a short distance (communication possible distance). Further, the reader / writer unit 18 writes the balance amount newly calculated by the CPU 10 to the electronic money recording medium. The electronic money recording medium is an IC card or a mobile phone terminal having an IC chip for storing balance amount data as electronic money.

  FIG. 11 is a diagram illustrating an arrangement example of the self-register device 1. For example, a self-register device 1 and a normal cash register for registering merchandise by a store clerk are arranged side by side in a face-to-face checkout counter of a retail store such as a convenience store. The clerk over the counter is for operating a normal cash register device, but the display surface of the second display unit 14 is arranged toward the side where the clerk is located. Therefore, when a problem occurs in the self-register device 1, the store clerk grasps the error contents by checking the second display unit 14 without moving to check the first display unit 13 beyond the counter or the like. It becomes possible to do. In addition, when no error has occurred, the store clerk can grasp the accumulated number of purchased products, the accumulated amount of purchased products, etc. by looking at the second display unit 14, so that the customer has not performed unauthorized product registration. It is also possible to confirm.

  The purchaser operates while looking at the first display unit 13 when performing the accounting process using the self-register device 1. When a problem occurs in the self-register device 1, an error code is displayed on the second display unit 14 having a display surface in a direction substantially opposite to the first display unit 13. Therefore, the store clerk located in a different place from the purchaser grasps the error contents by moving to the purchaser's original position and looking at the second display unit 14 without looking at the first display unit 13. It becomes possible to do.

  More specifically, the self-register device 1 has the following effects. For example, if the error content is “Receipt paper is out”, the content of the error is that the store clerk has moved to the purchaser's location and viewed the error information displayed on the purchaser's display. After that, it was necessary to go to the place of the self-register device again to take the receipt paper to a predetermined place and to deal with it. However, for example, when the error code displayed on the second display unit 14 is “0003”, the clerk remembers the contents of the error code or confirms the printed error code table, so that the clerk Since it is possible to grasp that the error content is “the receipt paper is broken”, the receipt paper is prepared in advance and then moved to the position of the self-register device 1 so that the receipt paper can be quickly supplied. . In this way, the self-register device is provided with a display unit that can be visually recognized by the store clerk, and error information that can identify each error is displayed on the display unit. It is possible to grasp the content of the error that is present and to deal with the error.

  Note that the subject that looks at the second display unit 14 and deals with the problem is not limited to the store clerk who operates the cash register device located next to the self-register device 1, but may be, for example, a store manager over the counter or other operations. A store clerk such as an assistant may be used. In any case, according to the self-register device 1, it is not necessary for the person dealing with the problem to move to the purchaser's position and look at the first display unit 13, and from the position different from the purchaser, the second display unit 14 The problem can be dealt with quickly.

  Next, an operation example when a problem occurs in the self-register device 1 will be described. FIG. 10 is a flowchart showing an operation example when a problem occurs in the self-register device 1. When detecting that a problem has occurred, the CPU 10 stops the accounting process (S01). The stop of the accounting process is to stop accepting a new barcode input using the scanner unit 17 or to press the “return to start” button or the “account” button on the first display unit 13. For example, stopping the processing accompanying the above, or stopping the reader / writer 18 from reading or writing the balance amount to the electronic money recording medium. Even if the accounting process is stopped, the CPU 10 accepts an operation related to the restoration of the self-register device 1. The operation related to the recovery includes an operation for displaying details of error contents on the first display unit 13 and an operation for restarting the self-register device 1. At this time, the CPU 10 causes the speaker unit 15 to reproduce an error sound (S02).

  The CPU 10 reads out an error code corresponding to the problem that has occurred from the error code table based on the determination criteria (S03). The CPU 10 displays the read error code on the second display unit 14 (S04). That is, the display on the second display unit 14 that displays information related to the products registered before the problem occurs, that is, the accumulated number of purchased products and the accumulated amount of purchased products, is switched to the display of the error code. Further, the CPU 10 displays the error window 131 shown in FIG. 7 on the first display unit 13 (S05).

  The CPU 10 also determines whether or not the confirmation button has been pressed (S06). If no, repeat the determination. When the confirmation button is pressed, that is, in the case of YES, the CPU 10 closes the error window 131 on the first display unit 14 (S07). The CPU 10 determines whether or not the problem that has occurred has been solved (S08). If no, repeat the determination. In the case of YES, that is, when the problem that has occurred is solved, the CPU 10 resumes the accounting process that was stopped in the process of S01 (S09).

[Modification]
FIG. 12 is a diagram illustrating a first modification of the display contents of the error window 131. The CPU 10 may display an error content or an error code as the error window 131 in the first display unit 13. When the confirmation button 132 in FIG. 7 is pressed, the CPU 10 displays an error window 131 as shown in FIG. With such a configuration, the purchaser can also grasp the content of the error and the error code by viewing the first display unit 13.

  FIG. 13 is a diagram illustrating a second modified example of the display contents of the error window 131. The CPU 10 displays the error window 131 shown in FIG. 7 on the first display unit 13, and when the confirmation button 132 of FIG. 7 is pressed, an error is further displayed on the first display unit 13 as shown in FIG. 13. You may make it display the password input box 133 (reception means) for displaying. If the correct password is not entered in the password input box 133, the CPU 10 does not display the error window 131 indicating the error content as shown in FIG.

  By being configured in this manner, it is possible to prevent a purchaser who cannot deal with an error from touching the self-register device 1 without permission. The clerk may also input (accepting means) the barcode (including the clerk identification information) described on the clerk card distributed to each clerk by the scanner unit 17 instead of the password. good.

  As shown in FIG. 4, a clerk flag may be further associated with each error code. The store clerk flag is data indicating whether or not a store clerk needs to respond. In FIG. 14, “1” is associated with an error code that needs to be handled by a store clerk, and “0” is associated with an error code that does not need to be handled by a store clerk.

  When the clerk flag corresponding to the problem that has occurred is “1”, the CPU 10 causes the first display unit 13 to display an error window 131 indicating that the clerk shown in FIG. 7 should be called, and the clerk flag is “0”. In the case of “,” the control may be performed such that the error window 131 directly showing the content of the error shown in FIG. In other words, for example, if the error code is 0005 and the balance is insufficient (the clerk flag is “0”), it is not an error until the clerk is called. A display may be displayed. In this case, by displaying the error code 0005 on the second display unit 14, if the customer takes time to process the error, the store clerk can go to the customer. In addition, the acquisition of the product code does not necessarily have to be realized by reading the barcode by the scanner unit, and the product that cannot be attached with the barcode is set on the touch panel of the first display unit 13 so that the product can be selected. You can keep it.

  The 1st display part 13 does not necessarily need to be comprised as a touchscreen, and an input device may be comprised separately. In this case, the first display unit 13 is configured as an image display device having no input function. The self-register device 1 has an input device corresponding to a “return to the beginning” button or a “checkout” button. Such an input device is configured using, for example, a pointing device such as a mouse, a keyboard, a numeric keypad, a dedicated button, or the like. In addition, such an input device is provided in the location which can be operated while viewing the 1st display part 13. FIG. For example, such an input device may be provided near the top, bottom, left, and right of the first display unit 13. Moreover, such an input device may be provided as an input device that can be freely determined without limiting the place for operation as an input device connected to the self-register device 1 by a cord or a wireless communication device. good.

  The second display unit 14 does not necessarily have to be provided in a direction substantially opposite to the first display unit 13, and the display surface only needs to be provided in a direction in which the store clerk can easily see. For example, in FIG. 11, only the second display unit 14 may be tilted in the direction in which the store clerk is located. That is, the 2nd display part 14 may be comprised so that the direction can be changed freely according to the arrangement | positioning condition of the self-register apparatus 1, and the position of a shop assistant.

  The receipt printing unit 16 may print an error code or error content when a problem has occurred in the self-register device 1. In this case, the receipt printing unit 16 may print the error code and the error content using the confirmation button 132 of the error window 131 as a trigger. With this configuration, the purchaser can convey the contents of the problem to the person who can restore the self-register device 1 by handing the printed receipt.

Further, the self-register device 1 may be configured to be able to perform settlement by other methods such as cash, credit card, debit card, etc., instead of settlement by electronic money.
The scanner unit 17 is not limited to a barcode, and any implementation may be used as long as it includes identification information (product code) of each product.

  In the above-described embodiment, the error code stored in the error code table is displayed on the second display unit 14 as the error content. However, the error code is not limited to the code and is displayed in characters on the 7-segment display. Also good. For example, since the error code 0003 is an error “Receipt paper is out”, for example, “PAPER” may be displayed.

In addition, when the second display unit 14 is configured using a liquid crystal display or the like, the content of the error may be directly displayed using characters or images instead of the error code.
In the above-described embodiment, the payment method is based on the electronic money card. However, the present invention is not limited to this, and an automatic change bill machine may be connected to the self-register device 1 and cash settlement may be employed.

In the above-described embodiment, the customer registers the product, and further, for example, settles with an electronic money card. However, the customer executes the product registration and prints the receipt on which the registered barcode is printed. It may be issued from the self-register device 1, and the customer may bring the receipt and only pay at the POS register where the store clerk is present.
When no problem has occurred, the second display unit 14 displays information related to the registered product. However, the present invention is not limited to this, and no information may be displayed.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.
