For example, the housing 1012 and the lid 1013 are made of metal. The radio wave reflecting material or the radio wave absorbing material prevents external radio waves from reaching the accommodation chamber 1012a. In addition, the radio wave reflecting material or the radio wave absorbing material prevents the radio wave generated in the reading device 101 from leaking to the outside of the reading device 101. As a result, the reading device 101 does not read radio waves from the outside. Further, the reading device 101 does not read the information from the external RFID tag.

The second detection unit 1014 is on the mating surface between the housing 1012 and the lid 1013 when the lid 1013 is in the closed state. The position of the second detection unit 1014 is not limited to this. The second detection unit 1014 detects (detects) the closed state or the open state of the lid body 1013. The second detection unit 1014 is a sensor using an arbitrary method. The detection method by the second detection unit 1014 includes, for example, a method using an infrared sensor or the like, but other methods may be used and are not particularly limited.

The first drive mechanism 1015 is on the mating surface between the housing 1012 and the lid 1013 when the lid 1013 is in the closed state. The position of the first drive mechanism 1015 is not limited to this. The first drive mechanism 1015 moves the lid body 1013. The first drive mechanism 1015 shifts the lid body 1013 from the closed state to the open state when the lid body 1013 is in the closed state. The first drive mechanism 1015 may include a mechanism for moving the lid body 1013. The configuration of the first drive mechanism 1015 is electromagnetic type, mechanical type, or the like, but is not particularly limited.

The communication I / F 19 is an interface for transmitting and receiving data to and from an external device connected to the POS device 1 by wire or wirelessly.

The reader / writer 1018 is in the reader 101. The reader / writer 1018 supplies power to the antenna 1017. The reader / writer 1018 radiates a radio wave for reading the information stored in the RFID tag 203 from the antenna 1017. The reader / writer 1018 reads the information contained in the signal transmitted by the radio wave from the RFID tag 203 received by the antenna 1017 (hereinafter referred to as a received signal). In this way, the reader / writer (reading unit) 1018 reads information from the RFID tag 203 via the antenna 1017. The reader / writer 1018 transmits the information read from the received signal to the control unit 11. The reader / writer 1018 can also transmit a signal for writing information (for example, the above-mentioned payment end information) to the RFID tag 203 to the antenna 1017. The reader / writer 1018 radiates a radio wave for transmitting this signal from the antenna 1017. In this way, the reader / writer 1018 can write information to the RFID tag 203 via the antenna 1017.

The third detection unit 1019 is located in the reading device 101. The third detection unit 1019 detects (detects) whether or not a product is contained in the storage chamber 1012a. For example, the third detection unit 1019 is a weight sensor that detects the weight of an object placed on the mounting surface 1011a. In this case, the third detection unit 1019 can detect that the product is contained in the storage chamber 1012a based on the weight detection. The third detection unit 1019 may be an optical sensor. The detection method by the third detection unit 1019 may be a method other than these, and is not particularly limited.

Next, the main functions of the control unit 11 in the POS device 1 will be described. FIG. 5 is a functional block diagram as an example of the POS device 1. The control unit 11 includes a read control unit 111, an open / close control unit 112, and a settlement processing unit 113.

The reading control unit 111 controls the reader / writer 1018 to read information from the RFID tag in the accommodation chamber 1012a. For example, the read control unit 111 controls to read the price information. The reading control unit 111 may control to read information other than price information from the RFID tag.

The open / close control unit 112 controls the lid body 1013 so as to transition from the closed state to the open state by using the first drive mechanism 1015. The open / close control unit 112 controls the lid body 1013 so as to transition from the open state to the closed state by using the second drive mechanism 1016.

The payment processing unit 113 performs payment processing based on the information read by the reader / writer 1018. For example, the payment processing unit 113 processes the credit card inserted into the card insertion slot 102 by the customer using the card reading unit 14. Alternatively, the settlement processing unit 113 processes the cash inserted into the banknote inlet / outlet 104 and the coin slot 105 using the coin insertion / delivery processing unit 15 and the bill entry / exit processing unit 16. Next, the payment processing unit 113 performs payment processing of the product by credit card or cash based on the price information read by the reader / writer 1018. Next, the payment processing unit 113 returns the credit card from the card insertion slot 102. Alternatively, the settlement processing unit 113 discharges the banknotes to be returned as fishing using the banknote entry / exit processing unit 16 from the banknote inlet / outlet 104. Alternatively, the settlement processing unit 113 discharges the coins to be returned as fishing using the coin discharge processing unit 17 to the coin outlet 106.

Next, the processing by the POS device 1 will be described. FIG. 6 is a flowchart that is an example of processing by the POS device 1. It is assumed that the lid body 1013 is in the closed state.

The first detection unit 108 detects whether or not there is a person in the vicinity of the POS device 1 (particularly the accommodation chamber 1012a) (Act1001). Generally, a person in the vicinity of the POS device 1 is a customer who intends to use the POS device 1.

When the first detection unit 108 does not detect a person in the vicinity of the POS device 1 (Act1001, No), the first detection unit 108 continues the process until it detects a person.

When the first detection unit 108 detects a person in the vicinity of the POS device 1 (Act1001, Yes), the open / close control unit 112 controls the lid body 1013 to open (Act1002). That is, in Act1002, the first drive mechanism 1015 shifts the lid body 1013 from the closed state to the open state based on the detection of a person by the first detection unit 108. In this way, the POS device 1 automatically opens the lid 1013 only when the customer approaches the POS device 1. The POS device 1 can physically inform the customer of the place where the product to be purchased should be put. Further, the POS device 1 can urge the customer to put the product in the storage chamber 1012a.

Next, the control unit 11 determines whether or not the product is contained in the storage chamber 1012a (Act1003). In Act1003, the control unit 11 can determine that the product is contained in the storage chamber 1012a based on the detection of the product by the third detection unit 1019. When the third detection unit 1019 is a weight sensor, the control unit 11 may process the Act 1003 as follows. While the customer is putting the product in the storage chamber 1012a, the weight measured by the third detection unit 1019 changes. When the customer finishes putting the product in the storage chamber 1012a, the weight measured by the third detection unit 1019 becomes stable. Therefore, when the weight measured by the third detection unit 1019 becomes stable, the control unit 11 may determine that the product is contained in the storage chamber 1012a. Since the POS device 1 is provided with a weight sensor, the control unit 11 can determine with high accuracy when the customer has finished putting all the products in the accommodation chamber 1012a.

When the control unit 11 determines that the product is not contained in the storage chamber 1012a (Act1003, No), the control unit 11 continues the process until it is determined that the product is contained in the storage chamber 1012a.

When the control unit 11 determines that the product is contained in the storage chamber 1012a (Act1003, Yes), the open / close control unit 112 controls the lid body 1013 to close (Act1004). In Act1004, the second drive mechanism 1016 has a lid based on the detection of the open state by the second detection unit 1014 and the detection by the third detection unit 1019 that the product is contained in the storage chamber 1012a. The body 1013 is transitioned from the open state to the closed state.

Next, the reading control unit 111 controls to read the price information from the RFID tags attached to all the products in the accommodation chamber 1012a (Act1005). In Act1005, the reader / writer 1018 reads the price information from the RFID tag via the antenna 1017 based on the detection of the closed state by the second detection unit 1014. The control unit 11 may control the display unit 107 to display the total price of the product based on the price information read by the reader / writer 1018.

Next, the settlement processing unit 113 performs settlement processing based on the price information read by the reader / writer 1018 (Act1006). The control unit 11 may control the reader / writer 1018 to write the payment end information in each RFID tag after the payment processing is completed. If the settlement processing unit 113 has not completed the settlement processing (Act1006, No), the settlement processing unit 113 continues the settlement processing.

When the payment processing unit 113 finishes the payment processing (Act1006, Yes), the open / close control unit 112 controls to open the lid body 1013 (Act1007). That is, in Act1007, after the settlement processing unit 113 finishes the settlement processing, the first drive mechanism 1015 shifts the lid body 1013 from the closed state to the open state. In this way, the POS device 1 automatically opens the lid 1013 when the payment process is completed. The POS device 1 can urge the customer to take out the product from the storage chamber 1012a. Further, the POS device 1 can prevent the customer from leaving the storage room 1012a without taking out the goods. The control unit 11 may control the display unit 107 to display information prompting the removal of the product from the storage chamber 1012a.

Next, the control unit 11 determines whether or not a product is contained in the storage chamber 1012a (Act1008). In Act1008, the control unit 11 can determine that the product is not contained in the storage chamber 1012a based on the non-detection of the product by the third detection unit 1019. When the third detection unit 1019 is a weight sensor, the control unit 11 may process Act1008 as follows. While the customer is taking out the product from the storage chamber 1012a, the weight measured by the third detection unit 1019 changes. When the customer finishes picking up all the products from the accommodation chamber 1012a, the weight measured by the third detection unit 1019 becomes stable. Therefore, when the weight measured by the third detection unit 1019 becomes stable, the control unit 11 may determine that the product is not contained in the storage chamber 1012a. Since the POS device 1 is provided with a weight sensor, the control unit 11 can determine with high accuracy when the customer has taken out all the products from the accommodation chamber 1012a.

Next, the open / close control unit 112 controls the lid body 1013 to close (Act 1009). That is, in Act1009, after the payment processing unit 113 finishes the payment processing, the second drive mechanism 1016 has a lid based on the detection by the third detection unit 1019 that the product is not contained in the storage chamber 1012a. The body 1013 is transitioned from the open state to the closed state. In this way, the POS device 1 can automatically close the lid 1013 after the customer brings back the product from the storage chamber 1012a. Therefore, the customer can safely walk around the POS device 1.

The POS device 1 may omit the processing of Act1003 in the following cases. For example, the customer may press the process start button on the input unit 13 after putting the product in the storage chamber 1012a. When the control unit 11 detects that the button is pressed after the processing of the Act 1002, the control unit 11 may then perform the processing of the Act 1004.

The POS device 1 may omit the processing of Act1003 and Act1004 in the following cases. For example, the customer may close the lid 1013 by himself / herself after putting the product in the storage chamber 1012a. In this case, the second detection unit 1014 detects the closed state of the lid body 1013. When the control unit 11 detects the closed state of the lid body 1013 after the processing of the Act 1002, the control unit 11 may then perform the processing of the Act 1005.

The POS device 1 may omit the processing of Act1008 in the following cases. For example, the control unit 11 may close the lid body 1013 after a certain period of time has elapsed after the treatment of Act1007. That is, after a certain period of time has elapsed from the time when the lid body 1013 transitions from the closed state to the open state after the payment processing unit 113 finishes the payment processing, the second drive mechanism 1016 in the Act 1009 opens the lid body 1013 from the open state. Transition to the closed state. This fixed time is a time assuming that the customer takes out the product from the accommodation room 1012a. Therefore, the lid 1013 does not close before the customer takes out all the products from the accommodation chamber 1012a. It should be noted that this fixed time can be arbitrarily set. In this example, the POS device 1 does not have to include the third detection unit 1019, which simplifies the configuration.

The POS device 1 may omit the processing of Act1008 in the following cases. For example, the control unit 11 may close the lid body 1013 when the first detection unit 108 no longer detects a person after the processing of the Act 1007. That is, when the first detection unit 108 no longer detects a person after the payment processing unit 113 finishes the payment processing, the second drive mechanism 1016 in the Act 1009 shifts the lid body 1013 from the open state to the closed state. Let me. When the first detection unit 108 does not detect a person, it corresponds to the time when the customer takes out the product from the accommodation chamber 1012a and leaves the POS device 1. Therefore, the lid 1013 does not close before the customer takes out all the products from the accommodation chamber 1012a. In this example, the POS device 1 does not have to include the third detection unit 1019, which simplifies the configuration.

According to the present embodiment, the POS device 1 can physically inform the customer how to use the POS device 1 by opening and closing the lid body 1013. Therefore, the operability of the POS device 1 for the customer is improved.

The second drive mechanism 1016 may be locked in the closed state until the second drive mechanism 1016 is closed by the Act 1009 and then opened again by the Act 1002. This is to prevent the customer from opening the lid 1013 without permission except when the POS device 1 is used for payment. If the lid body 1013 is locked, it is possible to prevent an adverse effect due to the lid body 1013 being opened unnecessarily.

The first drive mechanism 1015 may be a solenoid. The solenoid can slowly transition the lid 1013 from the closed state to the open state. Therefore, the customer in the vicinity of the lid 1013 can safely put in and take out the product.

The first detection unit 108 may detect whether or not there is a person facing the POS device 1. For example, the first detection unit 108 can detect whether or not there is a person facing the POS device 1 by recognizing the front surface of the face. Based on the detection of the person facing the POS device 1 by the first detection unit 108, the first drive mechanism 1015 shifts the lid body 1013 from the closed state to the open state. This is because a person other than the user of the POS device 1 may cross in front of the POS device 1. If the first detection unit 108 only detects whether or not there is a person in the vicinity of the POS device 1, the lid body 1013 will open unnecessarily. A person who wants to use the POS device 1 usually faces the POS device 1. The POS device 1 can open the lid 1013 only when the person who wants to use it is in the vicinity of the POS device 1.
