(Detecting means) and a stopper 73, and a cover 74 that covers from above the gap formed by the inner wall of the circular recess 70 and the side wall of the rotary base 71.

  The rotary pedestal 71 is attached to the main body 2 via a swivel mechanism that can rotate around a straight line passing through the center of the circle. Small holes 75 a and 75 b are formed on the upper surface of the rotating pedestal 71 so as to be fitted to the cylindrical protrusions 60 a and 60 b of the connecting member 6 and penetrate the lower part of the rotating pedestal 71. In addition, a protrusion 76 is provided on the side wall of the rotary base 71 in a direction substantially perpendicular to the display surface of the display unit 3 in a state where the connecting member 6 is fitted in the small holes 75a and 75b. Note that the control circuit of the display unit 3 and the control circuit of the main body 2 are connected to each other by a wiring that passes through the connecting member 6, the cylindrical protrusions 60a and 60b, and the small holes 75a and 75b.

  The mode changeover switch 72 has a clerk-side contact and a customer-side contact, and is substantially perpendicular to the left and right side walls of the main body 2 where the customer-side display unit 4 and the electronic settlement unit 5 are not provided. It is provided on a straight line passing through the center.

  The stopper 73 is provided at a position facing the mode changeover switch 72 on the inner wall surface of the circular recess 70, and the protrusion 76 passes even when the rotation base 71 is rotated and the protrusion 76 comes into contact. The shape is not possible.

  The relationship between the rotation of the rotary base 71 and the mode changeover switch 72 will be described with reference to the schematic diagram shown in FIG. When the display surface of the display unit 3 is directed to the clerk side with respect to the straight line connecting the circle center of the rotary base 71 and the mode changeover switch 72, the contact of the mode changeover switch 72 is connected to the clerk side contact. When the torque applied to the customer side by the user is applied to the display unit 3, the torque is transmitted to the rotary base 71 via the connecting member 6, and the rotary base 71 is rotated to the customer side by the swivel mechanism. At this time, when the protrusion 76 passes the installation position of the mode changeover switch 72, the protrusion 76 and the mode changeover switch 72 come into contact with each other, and the contact is switched to the customer side.

  In addition, in the state where the display surface of the display unit 3 is directed to the customer side with respect to the straight line connecting the center axis of the rotary base 71 and the mode changeover switch 72, the torque that the user rotates to the store clerk side is applied to the display unit 3.

Display 3a and touch panel 3b, display 4a and touch panel 4b of customer side display unit 4, electronic settlement unit 5, scanner I / F (Interface) 14 and the like.

  The memory 11 forms various working storage areas according to the processing scene. In particular, when an accounting business application 21 to be described later is being executed, a transaction flag F indicating whether or not a commercial transaction is being executed is formed.

  The mode changeover switch 72 outputs a control signal C1 to the CPU 10 when being switched to the clerk-side contact, and outputs a control signal C2 to the CPU 10 when being switched to the customer-side contact.

  The HDD 13 stores a database such as a PLU (Price Look Up) file 20 and application files such as an accounting business application (AP) 21. The PLU file 20 stores product data including the product name, unit price, etc. in association with the PLU code assigned to each product. The accounting business application 21 is an application that performs a series of accounting processes, and causes the merchandise sales data processing apparatus 1 to implement the accounting process in the clerk mode related to the so-called face-to-face sales method and the self mode related to the so-called self-checkout method.

  The display 3a of the display unit 3 is a display such as an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube), or an OEL (Organic Electro-Luminescence), and is used for various application screens and accounting processes according to instructions from the CPU 10. Information such as the product data of the registered products and the total amount of transactions is selectively displayed. The display 4a of the customer side display unit 4 is a display such as an LCD, CRT, or OEL, similar to the display 3a of the display unit 3, and in accordance with a command from the CPU 10, the total amount of transaction and the product with the PLU code input. Product data, advertising information for stores and products, etc. are selectively displayed.

  The touch panel 3b of the display unit 3 and the touch panel 4b of the customer-side display unit 4 are touch panels that employ, for example, a resistive film method. A voltage drop is generated according to a position touched by a user with a finger or a touch pen, and the amount of voltage drop is determined. It detects and calculates a contact position coordinate. The calculated contact position coordinates are notified to the CPU 10.

  The electronic settlement unit 5 includes an antenna for wireless communication, a transmission unit that transmits radio waves to an electronic money medium such as an IC card or a mobile communication terminal via the antenna, and electronic money for the radio waves transmitted by the transmission unit. A receiving unit that demodulates a response radio wave returned from the medium and obtains electronic money information. The electronic money information acquired by the receiving unit is notified to the CPU 10.

  The scanner I / F 14 is connected to a scanner 30 that is an external device. The scanner 30 optically reads a barcode bar pattern attached to a product or a label and decodes it into a PLU code. The PLU code detected by the scanner 30 is notified to the CPU 10 via the scanner I / F 14.

Next, the operation of the product sales data processing apparatus 1 configured as described above will be described.
[Accounting]
The accounting process is realized by software control by the accounting business application 21 stored in the HDD 13. In this process, the store clerk operates the merchandise sales data processing apparatus 1 to complete the transaction, or the customer operates the merchandise sales data processing apparatus 1 to complete the transaction. . Even when the accounting mode is set to either the clerk mode or the self mode, the transaction flag F stored in the memory 11 at the start of the accounting process is set to “1”, and the accounting process is completed. Transaction flag F is set to “0”.
Hereinafter, the accounting process in each of the clerk mode and the self mode will be described.

(Clerk mode)
The clerk mode is an accounting mode in which the clerk mainly operates by operating the user interface of the merchandise sales data processing apparatus 1. In the accounting process in the clerk mode, the clerk first scans the barcode attached to the purchased product with the scanner 30 and inputs the PLU code of the purchased product. The PLU code of the purchased product can be input by touching the touch panel 3b according to the display on the display unit 3.

  When the PLU code is input, the CPU 10 identifies the product data stored in the PLU file 20 in association with the input PLU code, and registers it in the work storage area for registering the product data formed in the memory 11. Go.

  When the input of the PLU code is completed for all of the purchased products, the store clerk operates the subtotal key displayed on the display unit 3. In response to this, the price of the transaction is calculated from the product data registered in the working storage area and displayed on the display unit 3 and the customer display unit 4. Further, the electronic payment unit 5 shifts to a state of waiting for communication with the electronic money medium.

  When the customer places the electronic money medium on the electronic payment unit 5, electronic money information is read from the electronic money medium. When the electronic payment information read at this time is notified from the electronic payment unit 5, the CPU 10 performs payment by electronic money according to a well-known procedure, and electronically stores a transaction history including detailed information of the transaction instead of issuing a receipt. Reply to money medium. In the electronic money medium, the transaction history returned from the merchandise sales data processing apparatus 1 at this time is stored and managed. Further, the CPU 10 stores the transaction history in a history management database provided in the HDD 13 and shifts to a state of waiting for the start of the next transaction. Thus, a series of accounting processes is completed.

(Self mode)
The self mode is an accounting mode in which the customer mainly operates by operating the user interface of the merchandise sales data processing apparatus 1. That is, in the self-mode accounting process, the customer himself / herself performs the operation described as being performed by the store clerk in the description of the store clerk mode.

  However, since the customer is generally unfamiliar with the operation of the merchandise sales data processing device 1, accounting guidance is displayed on the display unit 3 and the customer display unit 4. For example, in the input scene of the PLU code, a guidance indicating that the PLU code can be input by scanning the barcode attached to the product with the scanner 30 or touching the display unit 3, Touch the displayed subtotal key to display guidance and the like to shift to the payment scene. In addition, at the time of payment, an instruction is given to the electronic settlement unit 5 that the electronic money medium should be stored, and a message that the transaction details are to be transmitted to the electronic money medium is displayed. Thus, when a series of processing is completed, the display unit 3 displays the advertisement information of the store and the merchandise, and shifts to a state of waiting for the next accounting process.

[Mode switching processing]
Next, a mode switching process for switching between the clerk mode and the self mode will be described. FIG. 7 is a flowchart of processing executed by the CPU 10 in mode switching processing. This process is executed in parallel with the accounting process and the like based on an operation program that constitutes the accounting application 21.

  While the accounting business application 21 is being executed, the CPU 10 monitors the output from the mode changeover switch 72 (step S1). When the display unit 3 whose display surface is directed to either the store clerk side or the customer side is rotated so that the display surface faces the other, the projection 76 contacts the mode switch 72 and the contact is switched. At this time, the control signal C1 or the control signal C2 is output from the mode switch 72 to the CPU 10 in accordance with the contact after switching.

  When the CPU 10 detects that the control signal C1 output from the mode changeover switch 72 has changed to the control signal C2 or that the control signal C2 has changed to the control signal C1 (Yes in step S1), the CPU 10 refers to the memory 11. Then, it is determined whether the transaction flag F is set to “0” or “1” (step S2). When the transaction flag F is set to “1” (“F = 1” in step S2), that is, when the accounting process is currently being executed, the display 3a of the display unit 3 and the customer side display unit 4 A warning indicating that the accounting process is being executed is displayed on the display 4a (step S3).

  On the other hand, when the transaction flag F is set to “0” (“F = 0” in step S2), that is, when the current accounting process is not performed, the switching position of the current mode switch 72 is determined. (Step S4). When the control signal C1 is output from the mode changeover switch 72, the mode changeover switch 72 has been switched to the clerk side contact ("clerk side" in step S4), so the CPU 10 sets the accounting mode to the clerk mode. (Step S5). Specifically, an operation program for the clerk mode is read from the accounting business application 21 and executed, and a screen for the clerk mode is displayed on the display unit 3 or the customer side display unit 4.

  When the control signal C2 is output from the mode changeover switch 72, since the mode changeover switch 72 has been switched to the customer side contact (“customer side” in step S4), the CPU 10 sets the accounting mode to the self mode. (Step S6). Specifically, a self-mode operation program is read from the accounting business application 21 and executed, and a self-mode screen is displayed on the display unit 3 or the customer-side display unit 4.

  After switching the accounting mode in step S5 or step S6, the CPU 10 again monitors the control signal output from the mode switch 72 (step S1), and if the mode switch 72 is switched (step S1). (Yes in S1), the processing of Steps S2 to S6 is executed.

  As described above, the merchandise sales data processing apparatus 1 in the present embodiment detects the display direction of the display unit 3 with the mode changeover switch 72, and sets the accounting mode between the clerk mode and the self mode according to the detection result. Switch with. With such a configuration, the accounting mode can be switched quickly and easily without requiring a large-scale operation such as rotating the main body 2 placed on the register counter.

  Specifically, the display direction of the display unit 3 can be changed by attaching the display unit 3 to the main body 2 so as to be rotatable. Since such an attachment method does not require a particularly complicated mechanism, the configuration and appearance of the merchandise sales data processing apparatus 1 can be simplified.

  Further, the accounting mode is switched depending on whether the display direction is directed to the first range set on the store clerk side or the second range set on the customer stand side. Accordingly, the display direction of the display unit 3 can be changed to a desired direction within the first range when the clerk mode is set and within the second range when the self mode is set.

  In addition, an electronic payment unit 5 is provided on the customer 2 side of the main body 2 to enable payment using an electronic money medium. As a result, the customer can make a payment simply by putting the electronic money medium on the electronic payment unit 5, thereby facilitating the accounting process. Furthermore, when a terminal for electronic money payment is externally attached via a general-purpose interface or the like, problems such as giving a complicated impression of wiring or requiring installation space arise. If the unit 5 is integrated with the main body 2 at the standing position of the customer, it looks good and there is no need to worry about the installation position.

  In addition, when an attempt is made to switch between the clerk mode and the self mode during the execution of the commercial transaction, the fact that the commercial transaction is being executed is notified. As a result, it is possible to prevent a situation in which the accounting mode is erroneously switched while accounting is in progress.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above embodiment, the clerk mode and the self mode are switched by changing the display direction of the display unit 3. However, a mode that can be switched by changing the display direction of the display unit 3 may be further added. For example, the display direction of the display unit 3 is divided into three positions, that is, the clerk standing position side, the customer standing position side, and the middle of both. Then, the clerk standing position side is set to the clerk mode, the customer standing position side is set to the self mode, and the middle of both is set to the pause mode in which data input from each input device is not accepted. With such a configuration, for example, the store clerk must leave the cashier counter, but when the user does not want to function as the self mode, it is possible to set the sleep mode so that the customer's operation is not accepted.

  The accounting mode switching method is not limited to the method using the mode switching switch 72. For example, a contact is provided on the rotating pedestal 71, and when the display direction of the display unit 3 is directed to the store clerk side, the first circuit that contacts the contact of the rotating pedestal 71 to form an energization path, and the display unit 3 display The mounting mechanism 7 is provided with a second circuit that contacts the contact of the rotary base 71 to form a current-carrying path when the direction is on the customer side. When the CPU 10 monitors the state of the first and second circuits and sets the salesperson mode when the first circuit is energized, and the second circuit is energized. To set to self mode. In addition, various methods can be adopted depending on the structure of the commodity sales data processing apparatus to which the present invention is applied.

  Further, a card reader for reading a magnetic card such as a credit card may be provided on the customer's standing position side of the main body 2 so that card payment can be made based on the card information read from the credit card or the like. Further, the electronic money information reading method using the electronic settlement unit 5 may be a contact type in which the electronic money medium and the connection terminal are brought into communication instead of a non-contact type by wireless communication with the electronic money medium. Good.

  Further, a receipt printer may be built in or connected to the main body 2 and a receipt printed with detailed transaction information may be issued from the printer. In this case, an operation button for selecting whether or not a receipt is necessary may be displayed on the customer display unit 4 so that no receipt is issued from the printer when a receipt is not required.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, a well-known technique and a common technique may be combined within a range not departing from the gist.
