Description

  The present invention relates to a merchandise sales data processing apparatus such as an ECR (Electronic Cash Register) or a POS (Point of Sales) terminal.

  Merchandise sales data processing devices such as ECR (Electronic Cash Register) and POS (Point of Sales) terminals, and change machines used together with such merchandise sales data processing devices are generally called one customer. Often used in embodiments. In particular, in a convenience store that has undergone remarkable development in recent years, the usage mode of the product sales data processing apparatus, which is one customer, is generalized.

  In contrast, a system in which one cashier handles a plurality of product sales data processing devices (for example, Patent Documents 1 and 2), and conversely, a plurality of people are associated with one product sales data processing device. The so-called two-person system has also been widely used and implemented.

  A system in which one cashier handles multiple product sales data processing devices adopts a self-scan method that allows the customer to read the product data, and the cashier exclusively works with the customer (for money). Giving and receiving) and settlement operations (sales registration operations, etc.).

  A so-called two-person system is a method in which one product sales data processing apparatus is used by two people. In this method, the roles of the two persons are divided between the operator and the cashier. As an example of role assignment, an operator is engaged in a scanning operation for reading commodity data, and a cashier is engaged in a settlement operation or a settlement operation. As another example of the role assignment, the operator is engaged in the bagging work of the purchased product, and the cashier is engaged in the work of the product sales data processing apparatus.

  In the background art section, in addition to the general usage of a product sales data processing device, one customer, a system in which one cashier handles multiple product sales data processing devices, and vice versa We also introduced a so-called two-person customer service system in which multiple products are associated with the product sales data processing device.

  From the standpoint of efficiently selling customers, both a system in which one cashier handles multiple product sales data processing devices, a so-called two-person customer service system, and a product sales data processing device with one customer. In comparison with the general usage mode, a certain degree of efficiency can be achieved.

  However, in a system in which one cashier handles multiple product sales data processing devices, two lanes are required for scanning product data, and two product sales data processing devices are also required. The scale will increase. While it is possible to efficiently reach customers during busy periods, it is not possible to say that the space efficiency is high because one lane and one merchandise sales data processing device are not used during other times.

  In addition, the so-called two-person system, which handles customer sales efficiently by dividing roles between the operator and the cashier, for example, handles product sales data processing for two customers in parallel. You can't do it. For this reason, customers can be efficiently sought to some extent, but a great effect such as doubling efficiency cannot be expected.

  In addition, for example, considering usage at convenience stores, both a system in which one cashier handles multiple merchandise sales data processing devices and a so-called two-person customer service system are both appropriate usage modes. It can not be said.

  Next, functions that the control program stored in the HDD 157 of the POS terminal 101 causes the microcomputer 151 to execute will be described based on the flowcharts shown in FIGS. 6, 7, 14 to 16. In this case, a schematic diagram showing an example of the left / right registration table set in the RAM 155 shown in FIG. 8, a schematic diagram showing an example of the responsible person master table set in the RAM 155 shown in FIG. 9, FIG. 10, FIG. 17 and 18 are schematic diagrams of display screens displayed in the display area of the operator display 107, and display screens displayed in the display areas of the customer display 120 shown in FIGS. Referring to the schematic diagrams, FIGS. 1 to 5 are also used as necessary.

  In the POS terminal 101 after activation, the operation mode is selected according to the switching position of the mode key 108. That is, the microcomputer 151 sets the operation mode of the POS terminal 101 to a registration mode, a setting mode, a checkout mode, an inspection mode, etc. according to an output signal generated by the switching position of the mode key 108. In the present embodiment, the description of processing similar to that performed by the conventional POS terminal is omitted as processing in each mode except for the registration mode.

  On the other hand, in this embodiment, in the registration mode, the single mode corresponds to the usage mode in which one operator responds to one customer, and the usage mode in which two operators respond to two customers, respectively. Two modes of operation are allowed, with a corresponding dual mode.

  FIG. 6 is a flowchart showing a mode selection process between the single mode and the dual mode in the registration mode.

  When the operation mode of the POS terminal 101 is set to the registration mode by the switching operation of the mode key 108, two types of single use and dual use are selected for the initial screen display displayed on the operator display 107. A selection screen for enabling is displayed (not shown). Therefore, when the single use is selected (Y in step S101), the microcomputer 151 sets the POS terminal 101 to the single mode (step S102). When the dual mode is selected (N in step S101), the microcomputer 151 is set. Sets the POS terminal 101 to dual mode (step S103). That is, in the POS terminal 101 of the present embodiment, the microcomputer 151 constituting the data processing unit can be selectively set to the single mode and the dual mode.

  Here, in general, in a merchandise sales data processing apparatus such as a POS terminal, an operator (casher) who uses the apparatus is registered as a person in charge to clarify the location of responsibility for transactions and the like. Therefore, person-in-charge registration is also performed in the POS terminal 101 of the present embodiment. In this case, in the POS terminal 101 of the present embodiment, in the dual mode, an operator who operates the first lock key 116a and the first keyboard 110a and the first barcode scanner 111a constituting the first input means. And the second fastening key 116b and the operator who operates the second keyboard 110b and the second barcode scanner 111b constituting the second input means are separately registered as responsible persons. Such processing for responsible person registration is performed by the function of responsible person registration means executed by the microcomputer 151. Such responsible person registration means will be described next.

  FIG. 7 shows that the barcode scanner 111 and the keyboard 110 are registered as the first input means 111a and 110a and the second input means 111b and 110b, and the operator who uses the first input means 111a and 110a and the second input. It is a flowchart which shows the flow of a process which registers a person in charge with the operator who uses means 111b, 110b.

  When the microcomputer 151 constituting the data processing unit in the flowchart of FIG. 6 is set to the single mode (step S102) or to the dual mode (step S103), the microcomputer 151 executes the process of the flowchart of FIG. To do. That is, it is determined whether or not a dual mode declaration has been made in step S101 of FIG. 6 (step S151). If it is determined in this determination processing that the dual mode is not declared (N in step S151), the operator display 107 is displayed on the single mode screen (step S152). On the other hand, if it is determined that the dual mode is declared (Y in step S151), the operator display 107 is displayed on the dual mode screen (step S153). In step S154, the microcomputer 151 displays the screen ID and disables the touch panel 109. Accordingly, the touch panel 109 does not function. Examples of screen display at this time are shown in FIGS.

  FIG. 10 is a schematic view illustrating a screen ID display that is displayed so as to overlap the single mode screen display of the operator display 107. FIG. 11 is a schematic view illustrating a screen ID display that is displayed so as to overlap the dual mode screen display of the operator display 107.

  As is clear from FIG. 10, the single mode screen display illustrated in FIG. 10 displays a screen of one screen and one transaction mode, and displays one barcode 2001 as a data code as a screen ID. As is clear from FIG. 11, the dual mode screen display illustrated in FIG. 11 displays a screen of one screen and two transaction modes, and displays two barcodes 2002 as data codes as screen IDs (2002a 2002b). In the dual mode screen display illustrated in FIG. 11, two bar codes 2002a and 2002b are allocated to the right side and the left side as viewed from the operator in accordance with the two transaction screens being divided into left and right. It is. These bar codes 2002a and 2002b include codes for setting the bar code scanner 111 as first or second input means. In the present embodiment, as an example, the barcode 2001 displayed so as to overlap the single mode screen display includes a code that should be set with the barcode scanner 111 as the first input means. In the dual mode screen display, the barcode 2002a displayed on the right side includes a code to be set with the barcode scanner 111 as the first input means, and the barcode 2002b displayed on the left side thereof is the barcode scanner 111. Is included as a second input means.

  In the process shown in the flowchart of FIG. 7, the process waits for the barcode scanner 111 to read the barcode 2001 or 2002a, 2002b as a process subsequent to step S154 (step S155). The process in step S155 is a process for determining whether or not the POS terminal 101 has received data from the barcode scanner 111. That is, when the barcode scanner 111 reads the barcode 2001 or 2002a, 2002b, the barcode scanner 111 uses the read barcode 2001 or 2002a, 2002b data (screen ID) as its scanner ID ( Wirelessly transmitted to the POS terminal 101 together with a unique code that identifies the device itself. In response to this, the POS terminal 101 receives the screen ID and scanner ID wirelessly transmitted from the barcode scanner 111 via the wireless communication circuit 166. Therefore, if the microcomputer 151 of the POS terminal 101 receives the screen ID and scanner ID wirelessly transmitted from the barcode scanner 111, it determines that scanning is present (step S155), and the process proceeds to step S156. The received screen ID and scanner ID are analyzed. Then, the correspondence relationship between the received screen ID and the scanner ID is stored and saved in the left / right registration table 155a provided in the storage area of the RAM 155 illustrated in FIG. 8 (step S157). That is, in the left / right registration table 155a, the received screen ID corresponds to the area indicated as “right” or “left”, and the scanner ID corresponds to “scanner” whichever corresponds to “right” or “left”. It is registered in the column. However, the left / right registration table 155a is only schematically shown for convenience of explanation, and as an actual data process, the correspondence between the received screen ID and the scanner ID is stored and saved in the left / right registration table 155a. become. In the process of step S157, the barcode scanner 111 that has read the barcode 2001a or 2002b superimposed on the single mode screen display or the barcode 2002a or 2002b displayed on the dual mode screen display is read. The processing content is that the barcode scanner 111 included in the barcode 2001 or 2002a, 2002b is registered in conformity with the code to be set as the first or second input means. As a result, the single barcode scanner 111 or the two barcode scanners 111a and 111b are registered as one of the first input means and the second input means (scanner registration process).

  FIG. 12 is a rear view of the keyboard 110 showing a unique code attached to the back surface of each keyboard 110. In the present embodiment, a unique code that identifies each keyboard 110 is attached to the keyboard 110 in the form of a bar code 110c on the back surface. As the unique code expressed in the form of the barcode 110c in this way, as an example, a code common to the unique code that accompanies the input data wirelessly transmitted to the POS terminal 101 side as a code for identifying the own device can be used. As a result, the types of unique codes to be assigned to each part can be reduced, and unnecessary confusion that can easily occur when there are too many such unique codes can be prevented. In order to attach such a barcode 110c to the back surface of the keyboard 110, for example, a label on which the barcode 110c is printed is attached to the back surface of the keyboard 110, or the barcode 110c is directly attached to the back surface of the keyboard 110. Or print.

  In the process shown in the flowchart of FIG. 7, the used keyboard ID registration (keyboard registration process) is executed as a process following the used scanner ID registration (scanner registration process) in step S157 (steps S158 to 160). Therefore, first, it waits for the barcode scanner 111 to read the barcode 110c attached to the back surface of the keyboard 110 (step S158). The process in step S158 is a process for determining whether or not the POS terminal 101 has received data from the barcode scanner 111. That is, when the barcode scanner 111 reads the barcode 110c, the barcode scanner 111 uses the scanned barcode 110c data (keyboard ID) as its scanner ID (unique code for identifying its own device). At the same time, it is wirelessly transmitted to the POS terminal 101. In response to this, the POS terminal 101 receives the keyboard ID and scanner ID wirelessly transmitted from the barcode scanner 111 via the wireless communication circuit 166. Therefore, if the microcomputer 151 of the POS terminal 101 receives the keyboard ID and scanner ID wirelessly transmitted from the barcode scanner 111, it determines that scanning is present (step S158), and the process proceeds to step S159. The received keyboard ID and scanner ID are analyzed. Then, for example, using the work area of the RAM 155, the correspondence between the received keyboard ID and the scanner ID is stored and saved (step S160). That is, in the left / right registration table 155a, the keyboard ID is registered in the “keyboard” column corresponding to either “right side” or “left side”. However, the left / right registration table 155a is only schematically shown for convenience of explanation, and as an actual data process, the correspondence between the received keyboard ID and scanner ID is stored and saved in the left / right registration table 155a. become. In the process in step S160, the keyboard 110 with the barcode 110c read by the barcode scanner 111 registered as one of the first input means and the second input means is read. The processing content is to register as the same first input means or second input means as the barcode scanner 111. As a result, the single keyboard 110 or the two keyboards 110a and 110b are registered as either the first input unit or the second input unit (keyboard registration process).

  FIG. 13 is a front view of the name tag 2011 showing a unique code assigned to the name tag 2011 that identifies each operator. In the present embodiment, a name code 2011 assigned to each operator is given a unique code that identifies each operator in the form of a bar code 2012 at the lower right portion of the surface. In order to attach such a barcode 2012 to the surface of the name tag 2011, for example, a label on which the barcode 2012 is printed is attached to the surface of the name tag 2011, or the barcode 2012 is directly printed on the surface of the name tag 2011. Or

  In the process shown in the flowchart of FIG. 7, operator ID registration (responsible person registration process) is executed (steps S161 to 163) as a process subsequent to the use keyboard ID registration (keyboard registration process) in step S160. Therefore, first, it waits for the barcode scanner 111 to read the barcode 2012 attached to the surface of the name tag 2011 (step S161). The processing in step S161 is processing for determining whether or not the POS terminal 101 has received data from the barcode scanner 111. That is, when the barcode scanner 111 reads the barcode 2012, the barcode scanner 111 uses the scanned barcode data (operator ID) as its scanner ID (unique code for identifying the device). At the same time, it is wirelessly transmitted to the POS terminal 101. In response to this, the POS terminal 101 receives the operator ID and scanner ID wirelessly transmitted from the barcode scanner 111 via the wireless communication circuit 166. Therefore, if the microcomputer 151 of the POS terminal 101 receives the operator ID and scanner ID wirelessly transmitted from the barcode scanner 111, it determines that scanning is present (step S161), and the process proceeds to step S162. The received operator ID and scanner ID are analyzed. Then, for example, using the work area of the RAM 155, the correspondence between the received operator ID and the scanner ID is stored and saved (step S163). In other words, the operator ID is registered in the “operator” column corresponding to either “right side” or “left side”. However, the left / right registration table 155a is only schematically shown for convenience of explanation, and as an actual data process, the correspondence between the received operator ID and scanner ID is stored and saved in the left / right registration table 155a. become. The processing in step S163 is performed by the operator assigned the name tag 2011 with the barcode 2012 read to the barcode scanner 111 registered as either the first input means or the second input means. Is registered as an operator who uses the same first input means or second input means as that of the read barcode scanner 111. As a result, one operator or two operators are registered as responsible persons as operators who use either the first input means or the second input means (responsible person registration process).

  If responsible person registration is executed in step S163, the customer layer keys 116 provided on the two keyboards 110a and 110b are registered as the first closing key 116a and the second closing key 116b, and the two scanners 111a are registered. 111b and the two keyboards 110a and 110b are registered as the first input means 110a and 111a and the second input means 110b and 111b, respectively, and all the processes for registering the operators using them are respectively completed. Accordingly, in step S163, the person-in-charge registration process is executed immediately after the operator registration, and the merchandise sales data process at the POS terminal 101 is made executable. Here, the function of the registration means for executing the scanner registration process, the keyboard registration process, and the responsible person registration process is executed.

  Note that the touch panel 109 disabled in step S154 is enabled in step S164 following step S163, and its function is restored.

  FIG. 9 is a schematic diagram illustrating an example of a responsible person master table 155b set in the RAM 155. The responsible person master table 155b stores and saves the responsible person name for each responsible person code corresponding to the operator ID. That is, the person-in-charge code is the same code as the unique code expressed by the bar code 2012 attached to the operator ID and, in retrospect, the name tag 2011 assigned to each operator. The responsible person name is the name of the operator who has the name tag 2011 with the barcode 2012 representing the unique code that is the responsible person code. Therefore, after the person-in-charge registration is completed, the left and right operators are identified by the operator IDs from the left and right registration table 155a, and the person-in-charge codes corresponding to these operator IDs are retrieved from the person-in-charge master table 155b. It is possible to specify who is the person in charge corresponding to the person in charge code.

  FIG. 14 is a flowchart showing processing in the single mode. FIG. 17 is a schematic diagram illustrating a screen display example on the operator display 107 in the single mode, and FIG. 18 is a schematic diagram illustrating a screen display example on the customer display 120 in the single mode.

  In the single mode, first, the microcomputer 151 transmits a signal for lighting the first left and right display units 117a and 118a in green to the keyboard 101a and the barcode scanner 111a registered as the first input means. Only the first left and right display portions 117a and 118a are turned on (step S201). As a result, the LEDs constituting the first left and right display units 117a and 118a emit green light, and the operator configures the first input means of the two keyboards 101a and barcode scanners 111a. It is notified that only the keyboard 101a and the barcode scanner 111a can be used.

  Next, the microcomputer 151 sets the operator display 107 and the customer display 120 to full screen display (step S202). The full screen display means a display form in which only transaction information for one customer is displayed on the operator display 107 and the customer display 120. In such a single mode, a registration processing screen called from the image data file stored in the HDD 157 is displayed on the full screen on the operator display 107 and the customer display 120.

  FIG. 17 is an example of a full screen display on the operator display 107, and FIG. 18 is a schematic diagram showing a screen display example on the customer display 120 in the single mode.

  As shown in FIG. 17, the full-screen display on the operator display 107 is a PLU that displays bibliographic information column 107a indicating bibliographic information such as date and time, responsible person, etc., and eight types of PLU groups as PLU group tag A. It includes a group column 107b, a merchandise information column 107c for displaying merchandise information, a transaction information column 107d for displaying the total purchase amount, consumption tax, deposit amount and change amount, and a discount input column 107e.

  The microcomputer 151 displays the purchase history of the purchased product in the product information column 107c, and displays the total purchase amount, consumption tax, deposit amount, and change amount determined by the purchase history in the transaction information column 107d. Further, when the PLU group tag A is touch-selected on the touch panel 109, the microcomputer 151 pops up the product information of the products included in the PLU group. When the product information of the pop-up displayed product is touch-selected on the touch panel 109, the product code of the product is input, and the display in the transaction information column 107d is updated. Information displayed in the product information column 107c can be scrolled by a scroll key B included in the product information column 107c.

  The discount input field 107e includes a tag C to which a beer ticket, a coupon ticket and a gift certificate are assigned, and a beer ticket of the type selected by the tag C, an amount of a coupon ticket or a gift certificate, for example, a beer ticket with a tag C. When selected, it has a money key D of 6 columns and 3 rows indicating the amount of a beer ticket such as a 500 yen beer ticket, a 1000 yen beer ticket,. The amount key D is scrolled by a scroll key E displayed in the discount input field 107e. The microcomputer 151 displays the amount of the beer ticket, coupon or gift certificate selected by the tag C on the amount key D, and when the amount key D is touch-selected on the touch panel 109, the selected amount is reduced from the purchase amount. Then, the display of the transaction information column 107d is updated.

  As shown in FIG. 18, the full-screen display on the customer display 120 includes a date / time column 120a indicating the date / time, a current display column 120b displaying the product name, quantity and unit price of the most recently traded product, and purchasing. Purchase history column 120c for displaying the history of the product, transaction information column 120d for displaying the total purchase amount, consumption tax, deposit amount and change amount, commercial message column 120e for displaying a commercial message as commercial information, and other messages Includes a message field 120f for displaying.

  Next, the microcomputer 151 displays and outputs a commercial message in the commercial message column 120e of the customer display 120 (step S203). The commercial message may be stored and stored in advance in, for example, the HDD 157 even if the still image or the moving image of the commercial message acquired from the external device via the communication interface 167 is displayed and output in the commercial message column 120e of the customer display 120, for example. Either the still image or the moving image of the commercial message may be displayed and output in the commercial message column 120e of the customer display 120.

  Next, the microcomputer 151 waits for a product code input (step S204). The merchandise code is input by scanner input of a bar code attached to the merchandise by the bar code scanner 111a constituting the first input means or key input of the merchandise code by the keyboard 110a. In addition, the product code can be input by touch input with the touch panel 109 at a position corresponding to an item that allows the input of the product code displayed on the operator display 107.

  If it is determined that the product code has been input (Y in step S204), the microcomputer 151 executes processing for temporarily registering the product code input in the registration area in the sales buffer of the RAM 155 and storing the product data. (Step S205). And transaction data calculation is performed (step S206) and the screen display of the display 107 for operators and the display 120 for customers is updated (step S207). More specifically, the microcomputer 151 updates the display contents of the product information column 107c and the transaction information column 107d of the operator display 107, and the current display column 120b, the purchase history column 120c, and the transaction information column 120d of the customer display 120. Update the display content of.

  Thereafter, the microcomputer 151 waits for a product code input (step S204) until a deposit amount is input (Y in step S208). In the actual transaction, the deposit amount is input by the operator who has deposited the settlement amount from the customer pressing the enter key 115 in the keyboard 110 and inputting the deposit amount with the numeric keypad 113 in the keyboard 110. The In the single mode, the deposit amount is input by the first keyboard 110a constituting the first input means.

  If there is an input of the deposit amount using the numeric keypad 113 (Y in step S208), the microcomputer 151 registers the input amount in the RAM 155 (step S209), and determines whether or not the lock key 116a is input. (Step S210). The closing key 116a is a key for declaring the closing of a transaction related to a product for which product information has been input and performing settlement, and specifically, the customer key 116 functions as a closing key. In the single mode, the closing of the transaction is declared by the first closing key 116a included in the first keyboard 110a constituting the first input means.

  Next, when there is an input from the closing key 116a (Y in step S210), the microcomputer 151 calculates a change amount and calculates the transaction information column 107d of the operator display 107 and the transaction information column of the customer display 120. The change amount is displayed in the “fishing” field of 120d (step S211).

  Thereafter, the microcomputer 151 performs temporary registration of sales data using the work area of the RAM 155 (step S212), drives and controls the thermal printer 103 to issue the receipt 105 (step S213), and the drawer controller 169. The drawer open signal is output to the drawer 201 to release the drawer 201 (step S214). The receipt 105 is issued from the receipt issuing port 106 by the process of step S213.

  FIG. 15 is a flowchart showing processing in the dual mode, and FIG. 16 is a flowchart showing right processing and left processing in the dual mode.

  In the dual mode, first, the process shown in the flowchart of FIG. 15 is executed. That is, the microcomputer 151 transmits a signal for lighting the first left and right display units 117a and 118a in green to the keyboard 101a and the barcode scanner 111a registered as the first input unit, and the second The keyboard 101b and the barcode scanner 111b registered as input means transmit signals to turn on the second left and right display units 117b and 118b in orange, and the first left and right display units 117a and 118a and the second Both the left and right display portions 117b and 118b are turned on (step S301). As a result, the LEDs constituting the first left and right display units 117a and 118a emit green light, and the LEDs constituting the second left and right display units 117b and 118b emit orange light. For this reason, the keyboard 101a and the barcode scanner 111a registered as the first input means among the two provided keyboards 101a and the barcode scanner 111a are registered as the second input means. The keyboard 101a and the barcode scanner 111a are shown.

  Next, the microcomputer 151 sets the operator display 107 and the customer display 120 to split screen display (step S302). The split screen display means a display mode in a dual mode in which two operators respectively respond to two customers on the operator display 107 and the customer display 120. In such a dual mode, the registration processing screen called from the image data file stored in the HDD 157 is displayed on the operator display 107 and the customer display 120 in a split screen.

The commercial message may be stored and stored in advance in, for example, the HDD 157 even if the still image or the moving image of the commercial message acquired from the external device via the communication interface 167 is displayed and output in the commercial message column 120e of the customer display 120, for example. Either the still image or the moving image of the commercial message may be displayed and output in the commercial message column 120e of the customer display 120.

  In the dual mode, the process shown in the flowchart of FIG. 16 is executed following the process of the flowchart shown in FIG. The process shown in the flowchart of FIG. 16 is a series of processes from the input of the product code to the closing process in the merchandise sales data process. The right side process (FIG. 16B) and the left side process (FIG. 16A). Are executed separately and independently. Such separate and independent processing of the right side processing and the left side processing may be executed using the multitask function of the CPU 152 or may be executed by sharing the processing among the two CPUs 152. Since the basic flow of the right-side process and the left-side process is the same, here, description will be given with the same step code in FIG. 16, and only when the right-side process and the left-side process are different will be described separately. To do.

  First, the microcomputer 151 waits for a product code input (step S351). The product code input is executed by a barcode scanner input to the product by the barcode scanner 111 or a product code key input by the keyboard 110. In addition, the product code can be input by touch input on the touch panel 109 at a position corresponding to an item that allows the input of the product code displayed on the operator display 107 in the right display area 107R and the left display area 107L. Is possible.

  When it is determined that the product code has been input (Y in step S351), the microcomputer 151 executes a process of temporarily registering the product code input in the registration area in the sales buffer of the RAM 155 and storing the product data. (Step S352). At this time, the right side processing product code input by the first input means 109a, 110a, 111a and the left processing product code input by the second input means 109b, 110b, 111b are distinguished from each other, and the RAM 155 is distinguished. Are temporarily registered in the registration area of the sales buffer. Then, transaction data calculation is executed separately for right processing and left processing (step S353), and the screen display of the right display area 107R or the left display area 107L of the operator display 107 and the customer display 120 is updated. (Step S354). More specifically, the microcomputer 151 updates the display contents of the product information column 107c and the transaction information column 107d of the operator display 107, and the current display column 120b, the purchase history column 120c, and the transaction information column 120d of the customer display 120. Update the display content of.

  Thereafter, the microcomputer 151 waits for a product code input (step S351) until there is an input of the deposit amount from the first keyboard 110a or the second keyboard 110b (Y in step S355). In the actual transaction, the deposit amount is input by the operator who has deposited the settlement amount from the customer pressing the enter key 115 in the keyboard 110 and inputting the deposit amount with the numeric keypad 113 in the keyboard 110. The

  If there is an input of the deposit amount using the numeric keypad 113 (Y in step S355), the microcomputer 151 registers the input amount in the RAM 155 (step S356). At this time, the input amount is registered in the RAM 155 by distinguishing the amount input by the first keyboard 110a from the amount input by the second keyboard 110b. Thereafter, the microcomputer 151 determines whether or not the first tightening key 116a or the second tightening key 116b has been input (step S357). The first closing key 116a and the second closing key 116b are keys for declaring the closing of the transaction relating to the product for which the product information has been input and performing settlement. Specifically, the customer key 116 is the closing key. Function as.

  Next, when there is an input from the first closing key 116a or the second closing key 116b (Y in step S357), the microcomputer 151 calculates the change amount and calculates the corresponding amount on the operator display 107. The change amount is displayed in the “fishing” field of the corresponding transaction information field 120d of the transaction information field 107d and the customer display 120 (step S358). At this time, if there is an input from the first closing key 116a, the product for the right processing which is input by the first input means 109a, 110a, 111a and is temporarily registered in the registration area in the sales buffer of the RAM 155. When the change amount is calculated based on the code and the second closing key 116b is input, it is input by the second input means 109b, 110b, 111b and temporarily registered in the registration area in the sales buffer of the RAM 155. The change amount is calculated based on the left-side processing product code.

  After that, the microcomputer 151 uses the work area of the RAM 155 to distinguish between the right side processing and the left side processing, and executes temporary registration of sales data (step S359), and the first left and right arranged near the receipt issuing port 106. The display unit 119a and the second left / right display unit 119b are selectively turned on (step S360), the thermal printer 103 is driven and issued to issue a receipt 105 (step S361), and a drawer open signal is sent to the drawer controller 169. Is output to release the drawer 201 (step S362).

  At this time, under the control of the microcomputer 151, the green LED which is the first left and right display unit 119a disposed in the vicinity of the receipt issuing port 106 is turned on in the case of the right side processing, and the receipt issuing port in the case of the left side processing. The orange LED which is the second left and right display unit 119b arranged in the vicinity of 106 is turned on. As a result, the operator issues a receipt in the right-hand side processing when the first left and right display unit 119a, which is a green LED, is lit even though there is only one receipt issuing port 106, and the orange LED When the second left and right display unit 119b is turned on, it can be known that the receipt is issued in the left side processing. Here, the receipt 105 to be issued is the receipt 105 based on the product data input by the first input means 109a, 110a, 111a or the product data input by the second input means 109b, 110b, 111b. The function of the notifying means for distinguishing and notifying whether the receipt 105 is based or not is executed.

  FIG. 23 is a schematic diagram showing an example of a receipt 105 issued in the dual mode. The receipt 105 shown in FIG. 23 (b) has a plurality of star marks 105a printed on the right side thereof, and the receipt 105 shown in FIG. 23 (a) has a plurality of star marks on the left side thereof. A mark 105a is printed. In other words, the microcomputer 151 has a plurality of receipts 105 on the right side of the receipt 105 based on the product code for right processing input by the first input means 109a, 110a, 111a executed by the input of the first closing key 116a. Left star processing products printed by the second input means 109b, 110b, and 111b, which are executed by the input of the second tightening key 116b, are printed with the star mark 105a (see FIG. 23B). The receipt 105 based on the code is printed with a plurality of star marks 105a on the left side (see FIG. 23A). As a result, the operator can see at a glance whether the receipt 105 issued by the right side processing or the receipt 105 issued by the left side processing only by looking to which side the plurality of star marks 105a are printed. It becomes possible to recognize. In this sense, the type and form of the mark 105a may be any as long as it can distinguish between the receipt 105 issued by right side processing and the receipt 105 issued by left side processing. . Here, in the merchandise sales data processing, the receipt 105 is based on the merchandise data inputted by the first input means 109a, 110a, 111a or based on the merchandise data inputted by the second input means 109b, 110b, 111b. A function for distinguishing whether it is the receipt 105 or not and causing the thermal printer 103 to issue a print is executed.

  Regardless of whether the receipt 105 is on the left or right, a cash register No. And the name of the person in charge are printed. Cash register No. Is a number unique to the POS terminal 101 that issued and printed the receipt 105, and this number is stored and saved in the storage area of the RAM 155 as an example. Therefore, when issuing the print of the receipt 105 in step S361, the microcomputer 151 stores the registration number stored in the storage area of the RAM 155, for example. Is printed on the receipt 105. Such a cash register No. Is a number unique to the POS terminal 101, and therefore, the same number is printed on the receipt 105 when merchandise sales data is processed by either the left or right operator. On the other hand, the name of the person in charge prints the name of the operator who executed the operation for the merchandise sales data processing. That is, the microcomputer 151 uses the first or second input means (for example, the keyboard 110, the scanner 111, etc.) that has executed the product code input in step S351 at the time of processing the receipt issuance 361 or as a process at the preceding stage. The right and left operators are identified from the left and right registration table 155a according to the specified right side processing or left side processing by the operator ID, and the responsible person code corresponding to the operator ID is searched from the responsible person master table 155b. As a result, it is possible to identify who is the person in charge corresponding to the searched person-in-charge code, and the name of the person in charge is printed on the receipt 105. Here, in the merchandise sales data processing, the receipt issuing means for causing the thermal printer 103 to print and issue a receipt 105 printed with information that can specify the operator registered as the person in charge of the merchandise sales data processing together with the transaction information. The function is executed.

  In this way, when the first closing key 116a is pressed in steps S351 to S361, the merchandise sales data processing based on the merchandise data input by the first input means 109a, 110a, 111a is executed. When the second closing key 116b is pressed, the function of the closing means for executing the product sales data processing based on the product data input by the second input means 109b, 110b, 111b is executed.
