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.

JP 07-021463 A Japanese Patent Application Laid-Open No. 07-210755

  In the section of the prior art, in addition to the general usage mode of a product sales data processing device of one customer, a system in which one cashier handles multiple product sales data processing devices, 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.

  An object of the present invention is to obtain a merchandise sales data processing apparatus that can efficiently reach customers without using a large-scale apparatus.

The present invention relates to a merchandise sales data processing apparatus having a data processing unit for executing merchandise sales data processing based on inputted merchandise data, and a display for displaying information and a first barcode scanner for inputting data.

The data processing unit can be set to dual mode, which separately executes product sales data processing based on One bar code scanner and the corresponding display on one side are assigned to one customer, the second bar code scanner and the corresponding display on the other side are assigned to another customer, and one product sales data A processing device can now be used to get two customers. Further, when the data processing unit is set to the dual mode, the input of the product data by the first barcode scanner and the input of the product data by the second barcode scanner are the same as those of the product data when the product data is input. The display mode on the side corresponding to the barcode scanner that has been input is distinguished from the display mode other than when the product data is input.

In the merchandise sales data processing apparatus of the present invention, the data processing unit that executes merchandise sales data processing is input by the merchandise sales information based on the merchandise data input by the first bar code scanner and the second bar code scanner. Since the product sales information based on the product data is displayed on the display unit separately on the right side display and the left side display, and the mode setting is made to the dual mode that enables the product sales data processing to be executed independently on the left and right sides. The bar code scanner and the corresponding side display can be assigned to one customer, and the second bar code scanner and the corresponding side display can be assigned to another customer. The product sales data processing device can be used to get two customers, so it can efficiently reach customers without using a large-scale device Door can be. Further, when the mode is set to the dual mode, there is input of product data at the time of product data input between input of product data by the first barcode scanner and input of product data by the second barcode scanner . Since the display mode on the side corresponding to the other barcode scanner is differentiated from the display mode other than when the product data is input, the input of the product data by the first barcode scanner and the second bar code It is possible to clearly distinguish the input of product data by the code scanner.

Yes. As various data files, a product master file, a sales file, a screen data file, and the like are stored. Although not particularly illustrated, the product master file has a file structure that stores and holds a product name, a unit price, a department code, and the like in association with each product code of the product. The sales file has a file structure for storing and storing a merchandise sales history such as sales details and sales amount. The screen data file has a file structure for storing and holding various display data to be displayed on the operator display 107 and the customer display 120 in units of “pages” which are one screen of the display screen.

  The control program stored in the HDD 157 is written in the RAM 155 together with the product master file and the like when the POS terminal 101 is started, so that the microcomputer 151 can control the drive of each unit. Next, each unit that is driven and controlled by the microcomputer 151 will be described.

  The operator display 107 is connected to the bus line 153 via the operator display controller 158. When display data from the microcomputer 151 is input to the operator display controller 158, the operator display controller 158 is driven to a predetermined value. Display matters.

  The touch panel 109 is connected to the bus line 153 via the panel controller 159, and recognizes the position of the XY coordinates on the panel touched by the operator by the operation of the panel controller 159 to acquire coordinate data. A signal corresponding to the coordinate data is output to the microcomputer 151. When a signal is input to the microcomputer 151, the microcomputer 151 executes a predetermined process based on the signal.

  The customer display 120 is connected to the bus line 153 via the customer display controller 160, and when customer display data from the microcomputer 151 is input to the customer display controller 160, the customer display controller 160 is driven by the customer display controller 160. To display the specified items.

  Here, in the usage mode in which two operators respectively respond to two customers, the display on the operator display 107 and the customer display 120 is divided into left and right, and the input function of the touch panel 109 is also for the right. As described above, it is separated for the left side. Such a two-part process is easily realized by controlling the coordinate positions of the operator display 107 and the customer display 120 for displaying information and controlling the coordinate position of the touch panel 109 for inputting data. The However, in particular, regarding the operator display 107 and the customer display 120, information only needs to be displayed as a result of being divided into two, so a technology that can realize such information display, for example, a pop-up display technology, etc. It is possible to perform two-segment display using various techniques.

  The mode key 108 is connected to the bus line 153 via the mode key controller 161, and inputs a signal corresponding to the switching position to the microcomputer 151 by the operation of the mode key controller 161. In response to the output signal from the mode key 108, the microcomputer 151 sets the operation mode of the POS terminal 101 to each operation mode such as a registration mode, a setting mode, a payment mode, and an inspection mode.

  The scanner pad 121 for a non-contact card provided on the back side of the POS terminal 101 is connected to the bus line 153 via the scanner pad controller 162 and is connected to the microcomputer 151 by the operation of the scanner pad controller 162. The information stored in is output.

Further, the thermal printer 103 includes a cutter unit (not shown), and the cutter unit is also driven and controlled by the microcomputer 151. As a result, the thermal printer 103 performs the function of a receipt printer that prints necessary information as a receipt on a receipt sheet, which is a long sheet (not shown), and cuts and issues it as a receipt from the receipt issuing port 106.

  A left / right display unit 119 (LED) including a first left / right display unit 119a and a second left / right display unit 119b arranged in the vicinity of the receipt issuing port 106 in the thermal printer 103 is connected to a bus via an LED controller 164. It is connected to the line 153 and driven and controlled by the microcomputer 151.

  The drawer 201 is connected to the bus line 153 via the drawer controller 169 and is driven and controlled by the microcomputer 151. The drawer controller 169 outputs a drawer open signal to the drawer 201 in accordance with an instruction from the CPU 152. When the drawer 201 receives the drawer open signal, the solenoid (not shown) is driven to open the latch of the drawer 202 by a latch mechanism (not shown). As a result, the drawer 202 is urged by the extension force of a compression spring (not shown) built in the drawer 201 and opened.

  Next, as described above, the keyboard 110 and the barcode scanner 111 transmit data to the microcomputer 151 of the POS terminal 101 via wireless. Therefore, in the present embodiment, the wireless communication interface 165 is connected to the microcomputer 151 via the bus line 153, and the wireless communication circuit 166 is connected to the wireless communication interface 165. The wireless communication circuit 166 includes a first keyboard 110a and a first barcode scanner 111a that constitute first input means, and a second keyboard 110b and a second barcode scanner 111b that constitute second input means. Wireless communication with the network. Therefore, each of the first keyboard 110a, the first barcode scanner 111a, the second keyboard 110b, and the second barcode scanner 111b also includes a wireless communication circuit (not shown), and each has a specific frequency. Wireless communication is possible with the wireless communication circuit 166 on the POS terminal 101 side using the band. As described above, the keyboard 110 and the barcode scanner 111 each have a built-in battery (not shown) due to a structure in which data is transmitted to the microcomputer 151 of the POS terminal 101 via wireless, and wirelessly using the battery as a drive source. Execute communication operation. Since the wireless communication between the keyboard 110 and the barcode scanner 111 and the POS terminal 101 side is an existing technology, the details thereof are omitted.

  A communication interface 167 is also connected to the bus line 153 and is controlled by the microcomputer 151. The communication interface 167 is connected to an external device such as a host computer, and enables data transmission / reception between the external device and the microcomputer 151 via the LAN line.

  Further, in addition to the ROM 154 and the RAM 155, a VRAM (Video Random Access Memory) 168 is connected to the microcomputer 151 via the bus line 153 in the POS terminal 101. For example, the VRAM 168 is based on display data in units of “pages” stored in the screen data file of the HDD 157, and includes product names, unit prices, image data, etc. included in the display data extracted from the product master file or product image file. Are expanded at a high speed and output to the operator display controller 158 and the customer display controller 160. The display data output to the operator display controller 158 and the customer display controller 160 is displayed on the operator display 107 and the customer display 120.

  In addition, not only the POS terminal 101 of the present embodiment but also a general structure of the POS terminal, for example, when a product code is input by the barcode scanner 111, an acoustic for notifying the operator and the customer of the input. For example, it has a structure that generates sound such as “beep”. In this embodiment, for such a structure, as an example, a speaker 171 is connected to the microcomputer 151 via the bus line 153 via the acoustic controller 170.

  Here, in this embodiment, when the microcomputer 151 that constructs the data processing unit is set to the dual mode, the product code is input by the first input means, for example, the product by the barcode scanner 111a. Different types of sound at the time of product code input, such as barcode scanner input or the like, and product code input by the second input means, for example, barcode scanner input or the like attached to the product by the barcode scanner 111b To distinguish (identification means). As a configuration for this, the acoustic controller 170 is used in the dual mode when the product code is input by the first input means executed by the scanner input of the barcode attached to the product by the barcode scanner 111a, and the barcode scanner. When the product code is input by the second input means executed by the scanner input of the barcode attached to the product according to 111b, for example, the sound in which “pitch”, “tone”, and “number of times” are changed is a speaker. 171 to output. To change the “pitch”, the frequency of the sound output from the speaker 171 can be changed, and the pitch of the sound can be changed between when the product code is input by the first input means and when the product code is input by the second input means. It ’s fine. To change the “tone”, it is only necessary to change the acoustic characteristics superimposed on the acoustic frequency waveform. As an example, when a product code is input by the first input unit, a sound of “beep” may be used, and when a product code is input by the second input unit, a sound other than the sound of “beep” may be used. In order to change the “number of times”, the frequency waveform of the sound may be changed to a repetitive type. As an example, when a product code is input by the first input means, a “beep” sound is used, and when a product code is input by the second input means, a “beep” sound is used.

  The function of such an identification means is that, in the dual mode, the product code is input by the first input means executed by the barcode scanner attached to the product by the barcode scanner 111a, etc. This is a function for notifying the operator and the customer that the product code has been input by the second input means executed by the scanner input of the barcode attached to the product by the code scanner 111b. Therefore, if such an object can be achieved, the type of sound at the time of inputting the product code between the input of the product code by the first input means and the input of the product code by the second input means is set. Not only the method of changing the sound controller 170 but also other methods may be adopted. For example, the sound source may be different when the product code is input by the first input means and when the product code is input by the second input means. In order to make the sound source different, for example, the speakers 171 are installed on the right side and the left side of the POS terminal 101. For example, when the product code is input by the first input means, it is installed on the right side as viewed from the operator. The notification sound is output from the speaker 171 and the notification sound is output from the speaker 171 installed on the left side as viewed from the operator when the product code is input by the second input means. As another example, the bar code scanner 111a and the like constituting the first input means and the bar code scanner 111b and the like constituting the second input means are provided with a circuit configuration that can output a notification sound, and the first When the product code is input by the input means, a notification sound is output from the barcode scanner 111a or the like installed on the right side when viewed from the operator, and when the product code is input by the second input means, the barcode scanner installed on the left side when viewed from the operator The notification sound is output from 111b or the like.

  Further, in the dual mode, in order to distinguish between the input of the product code by the first input means and the input of the product code by the second input means, the input of the product code by the first input means and the second input You may make it use together the method of changing the kind of sound and the method of changing the generation source of a sound by the time of the input of the product code by a means.

  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. In this case, it is displayed in the schematic diagram of the display screen displayed in the display area of the operator display 107 shown in FIGS. 10 and 12 and in the display area of the customer display 120 shown in FIGS. 11, 13 to 15. 1 to 4 are also used as needed, referring to the schematic diagram of the display screen.

  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 single mode and the dual mode can be selected.

  FIG. 7 is a flowchart showing processing in the single mode. FIG. 10 is a schematic diagram illustrating a screen display example on the operator display 107 in the single mode, and FIG. 11 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 the lighting signals of the first left and right display units 117a and 118a to the keyboard 110a and the barcode scanner 111a constituting the first input means, and the first left and right display units thereof. Only the display units 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 110a and the barcode scanner 111a. It is notified that only the keyboard 110a 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. 10 is an example of a full screen display on the operator display 107, and FIG. 11 is a schematic diagram showing a screen display example on the customer display 120 in the single mode.

  As shown in FIG. 10, the full-screen display on the operator display 107 includes a bibliographic information column 107a indicating bibliographic information such as date and time, a person in charge, etc. 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.

  In the dual mode, the process shown in the flowchart of FIG. 9 is executed following the process of the flowchart shown in FIG. The process shown in the flowchart of FIG. 9 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. 9B) and the left side process (FIG. 9A). 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, the same step symbols in FIG. 9 are used for explanation, and only when the right-side process and the left-side process are different, both are explained 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.

  If it is determined that a product code has been input (Y in step S351), right or left input notification processing is executed (step S351a). This input notification process is executed for the purpose of notifying an operator and a customer that a product code has been read and input. Therefore, in this embodiment, the acoustic controller 170 is controlled by the CPU 152, and the acoustic controller 170 inputs the right-side processing product code by the first input means 109a, 110a, and 111a and the second input means 109b. , 110b, 111b, the speaker 171 outputs different types of sounds depending on the left-side processing product code. In this case, as described above, as another embodiment, an identification notification form in which sound is output from different sources instead of different types of sound may be employed, or a method of different types of sound is used. And a method of identifying and reporting that uses a different method for different sound sources may be adopted.

  Also, as the input notification process in step S351a, the input of the product code for the right side processing by the first input means 109a, 110a, 111a and the input of the product code for the left side processing by the second input means 109b, 110b, 111b are performed. Is notified not only by the difference in the type of sound and the generation source, but also by the difference in display mode for the operator display 107 and the customer display 120. That is, as the input notification process in step S351a, in this embodiment, the operator display controller 158 and the customer display controller 160 are controlled by the CPU 152, and the operator display controller 158 and the customer display controller 160 are The display frame of the right display area 107R and the left display area 107L on the operator display 107 and the display frame of the right display area 107R and the left display area 107L on the customer display 120 are represented by the first input means 109a, When the product code for the right processing by 110a, 111a is input or when the product code for the left processing by the second input means 109b, 110b, 111b is input, they are blinked. That is, when the product code for the right processing is input by the first input means 109a, 110a, 111a, the operator display controller 158 blinks the display frame of the right display area 107R on the operator display 107. The customer display controller 160 causes the display frame of the left display area 107L on the customer display 120 to blink. Further, when the product code for the left side processing is input by the second input means 109b, 110b, 111b, the operator display controller 158 causes the display frame of the left side display area 107L on the operator display 107 to blink. The customer display controller 160 causes the display frame of the right display area 107R on the customer display 120 to blink. As a result, the product code for the right side processing was input by the first input means 109a, 110a, 111a, and the product code for the left side processing was input by the second input means 109b, 110b, 111b. This can be effectively notified to the operator and the customer.

  As another embodiment, the operator display controller 158 and the customer display controller 160 include a display frame of the right display area 107R and the left display area 107L in the operator display 107, and a right display in the customer display 120. The display frame of the area 107R and the left display area 107L is displayed on the left side by the first input means 109a, 110a, 111a when the product code for the right side processing is input or by the second input means 109b, 110b, 111b. When entering a code, each may be displayed in a color different from the initial set color. That is, as described above, the display frame of the right display area 107R in the operator display 107 is displayed in green, the display frame of the left display area 107L is displayed in orange, and the right display area 120R in the customer display 120 is displayed. The display frame is displayed in orange, and the display frame in the left display area 120L is displayed in green. Therefore, when a product code for right processing is input by the first input means 109a, 110a, 111a, the operator display controller 158 displays the display frame of the right display area 107R in the operator display 107 on the customer display. The controller 160 displays the display frame of the left display area 107L on the customer display 120 in a color other than green, which is the default color, for example, red or blue. When the product code for the left side processing is input by the second input means 109b, 110b, 111b, the operator display controller 158 displays the display frame of the left side display area 107L in the operator display 107 for the customer display. The controller 160 displays the display frame of the right display area 107R in the customer display 120 in a color other than the orange color that is the initial setting color, for example, red or blue. As a result, the product code for the right side processing was input by the first input means 109a, 110a, 111a, and the product code for the left side processing was input by the second input means 109b, 110b, 111b. This can be effectively notified to the operator and the customer.

  The function of the identification unit is executed by the processing in step S351a described above.

  As processing subsequent to step S351a, the CPU 152 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 by the microcomputer 151 (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 S213).

  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.
