[Second Embodiment]
The settlement device and the control method of the settlement device according to the second embodiment of the present invention will be described with reference to FIG. The same components as those of the settlement device and the control method of the settlement device according to the first embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified.

The configuration of the POS system 2 and the settlement device 10 according to the present embodiment is the same as the configuration of the POS system 2 and the settlement device 10 according to the first embodiment. In the present embodiment, the switching operation of the code scanner 124 and the RFID reader 126 according to the operation mode of the settlement device 10 and the control method for realizing the operation will be described with reference to FIG. FIG. 6 is a flowchart showing a switching operation of the reading unit in the settlement device 10 according to the present embodiment. In the present embodiment, both the code symbol and the RFID tag are attached to the product sold at the store 1.

As shown in FIG. 6, the CPU 102 of the settlement device 10 determines whether or not the operation mode switching of the settlement device 10 has been executed as in the first embodiment (step S202), and the operation mode switching is executed. Wait for it to be done (step S202, NO).

When it is determined that the operation mode switching has been executed (steps S202, YES), the CPU 102 determines whether or not the operation mode switching is switching from the manned cash register mode to the self-checkout mode (step S204). The CPU 102 functions as a read control unit that controls the code scanner 124 and the RFID reader 126 as follows based on the determination result of switching the operation mode.

When it is determined that the switching of the operation mode is the switching from the manned cash register mode to the self-checkout mode (step S204, YES), the CPU 102 as the read control unit operates only the RFID reader 126 so that the product information can be read (step). S206). That is, the CPU 102 controls the code scanner 124 and the RFID reader 126, and operates only the RFID reader 126 of the code scanner 124 and the RFID reader 126 with the product information readable. In this case, the CPU 102 can set the code scanner 124 so that the product information cannot be read, for example, by stopping the operation of the code scanner 124 or putting the code scanner 124 in a hibernation state.

In this way, when the checkout device 10 operates in the self-checkout mode, the customer can read and register the product information of the product he / she purchases by using the RFID reader 126 that operates so that the product information can be read. Since the customer can have the RFID reader 126 read the product information of the product simply by placing the product on the seat antenna 126a of the RFID reader 126, the product information can be read smoothly in a short time.

It is not necessary that all the products sold in the store 1 have RFID tags attached. For example, it is possible to prevent the RFID tag from being attached to a specific product that requires confirmation measures such as age confirmation by a clerk at the time of sale described later. As a result, the specific product without the RFID tag can be made into a product that can be sold only in the manned cash register mode.

On the other hand, when it is determined that the switching of the operation mode is the switching from the self-registration mode to the manned registration mode (step S204, NO), the CPU 102 as the read control unit operates only the code scanner 124 so that the product information can be read. (Step S208). That is, the CPU 102 controls the code scanner 124 and the RFID reader 126, and operates only the code scanner 124 among the code scanner 124 and the RFID reader 126 with the product information readable. In this case, the CPU 102 can set the RFID reader 126 so that the product information cannot be read, for example, by stopping the operation of the RFID reader 126 or putting the RFID reader 126 in a hibernation state. Further, for example, the CPU 102 can stop the output of radio waves from the seat antenna 126a of the RFID reader 126, and set the RFID reader 126 so that the product information cannot be read.

In this way, when the checkout device 10 operates in the manned cash register mode, the store clerk can read and register the product information of the product purchased by the customer by using the code scanner 124 that operates so that the product information can be read. Since the clerk picks up the product purchased by the customer and reads the product information by the code scanner 124 for each product, the clerk can surely confirm the product to be sold. Thereby, for example, it is possible to more reliably prevent the sale of defective products, the sale of foods whose expiration date or expiration date has passed, and the like.

As described above, the CPU 102 of the settlement device 10 operates either the code scanner 124 or the RFID reader 126, which is a reading unit, so that the product information can be read, depending on the operation mode. While the settlement device 10 is in operation, the switching operation of the reading unit shown in FIG. 6 is repeated.

As described above, according to the present embodiment, the reading unit capable of reading the product information is switched to the code scanner 124 or the RFID reader 126 according to the operating mode of the settlement device 10, so that more appropriate reading is performed according to the operating mode. You can select the part. Therefore, according to the present embodiment, it is possible to smoothly execute the accounting settlement process for the customer depending on the situation.

In the above description, the case where either the code scanner 124 or the RFID reader 126 is operated so that the product information can be read according to the operation mode of the settlement device 10 has been described, but the present invention is not limited to this.

For example, the CPU 102 can operate both the code scanner 124 and the RFID reader 126 so that the product information can be read in the manned cash register mode, while the CPU 102 can operate only the RFID reader 126 so that the product information can be read in the self-checkout mode. With this configuration, the RFID reader 126 can efficiently read and register the product information in both the manned cash register mode and the self-checkout mode.

That is, the CPU 102 interrupts the reading of the product information in the self-registration mode.

Next, the CPU 102 executes a response process for calling the clerk for confirmation measures by the clerk regarding the specific product (step S308). As a corresponding process, the CPU 102 transmits, for example, a notification for calling the clerk to a terminal owned by the clerk, a terminal installed in the backyard where the clerk waits, or the like via the network 40. Further, as a corresponding process, the CPU 102 can also ring, for example, a ringing tone for calling a clerk.

Further, the CPU 102 can execute a notification process for notifying the customer that the clerk is being called, in addition to the corresponding process for calling the clerk. The CPU 102 can notify the customer that the store clerk is being called, for example, by displaying on the second display 112, voice guidance, or the like.

On the other hand, if it is determined that the product is not a specific product (step S304, NO), the CPU 102 registers the product information of the product (step S310).

Next, the CPU 102 determines whether or not the customer has input an instruction to execute the accounting settlement process to the settlement device 10 (step S312). The customer can input the execution instruction of the accounting settlement process to the settlement device 10 by the touch input to the second display 112.

If it is determined that there is no input of the execution instruction of the accounting settlement process (step S312, NO), the CPU 102 proceeds to step S302 and continues to acquire the product information for the other products.

On the other hand, if it is determined that the execution instruction of the accounting settlement process has been input (step S312, YES), the CPU 102 executes the accounting settlement process of the product purchased by the customer (step S314).

As described above, in the present embodiment, when the checkout device 10 operates in the self-checkout mode, when the product purchased by the customer includes a specific product that requires confirmation measures by a clerk, the checkout device 10 in the self-checkout mode Suspend operation. Therefore, according to the present embodiment, when the checkout device 10 operates in the self-checkout mode, it is possible to reliably prevent the specific product from being sold without the confirmation measures taken by the clerk.
