The display unit 107 is arranged at the upper stage of the POS device 1. The display unit 107 displays various information at the time of payment processing. For example, the display unit 107 is a liquid crystal display.

The first detection unit 108 is arranged in the upper stage of the POS device 1. The first detection unit 108 is arranged in the vicinity of the display unit 107. The first detection unit 108 detects (detects) whether or not there is a person in the vicinity of the reading device 101. The first detection unit 108 detects whether or not there is a person within a predetermined distance from the reading device 101. The range in the vicinity of the POS device 1 in which the first detection unit 108 detects a person is not particularly limited. For example, the first detection unit 108 is a motion sensor. The detection method by the first detection unit 108 includes, for example, a method using infrared rays and the like, but other methods may be used and are not particularly limited.

Next, the configuration of the reading device 101 will be described. FIG. 2 is an external view of the reading device 101 as an example.
The reading device 101 includes a mounting table 1011, a housing 1012, a lid body 1013, a second detection unit 1014, a first drive mechanism 1015, and a second drive mechanism 1016.

The mounting table 1011 is a plate-shaped member on which the mounting surface 1011a is formed. On the mounting surface 1011a, the product with the RFID tag is placed as it is, or the basket in which the product is placed is placed. The mounting surface 1011a is a horizontal plane. The mounting table 1011 is made of a material having radio wave transmission property. For example, the mounting table 1011 is an insulator. The mounting table 1011 is made of wood, glass, or the like. The reason why the mounting table 1011 is made of such a material is to transmit radio waves for reading and writing to RFID.

The housing 1012 is the exterior of the reading device 101. The housing 1012 is provided with a storage chamber 1012a for accommodating goods inside the housing 1012. The storage chamber 1012a is configured to be large enough to accommodate the product as it is or the basket containing the product. The containment chamber 1012a is formed by a plurality of surfaces. The space inside the accommodation chamber 1012a is separated from the outside of the reading device 101 by a plurality of surfaces. For example, the storage chamber 1012a has a box shape composed of six surfaces. The number of surfaces forming the accommodation chamber 1012a is not limited to this. The housing 1012 houses the mounting table 1011 inside. The mounting surface 1011a is included in a plurality of surfaces forming the storage chamber 1012a.

The housing 1012 includes a first inner surface 1012b and an opening 1012c.
The first inner surface 1012b includes a plurality of surfaces. The first inner surface 1012b is included in a plurality of surfaces forming the accommodation chamber 1012a.

The opening 1012c is formed in the housing 1012 for putting the product into the storage chamber 1012a. The opening 1012c leads into the containment chamber 1012a. The opening 1012c is formed in the housing 1012 with a size that allows the basket to be taken in and out. The opening 1012c is formed on a surface extending in a substantially vertical direction constituting the housing 1012. The opening 1012c may be formed at any position on the housing 1012.

The lid body 1013 opens and closes the opening 1012c. The lid body 1013 rotates about a rotation axis provided on one end side in the vertical direction. When the lid body 1013 is in a state where the opening 1012c is opened (hereinafter, referred to as an open state), the customer can put the product into the storage chamber 1012a through the opening 1012c. The lid body 1013 includes a second inner surface 1013a. When the lid body 1013 is in a state in which the opening 1012c is closed (hereinafter referred to as a closed state), the second inner surface 1013a is included in a plurality of surfaces forming the storage chamber 1012a.

As described above, the accommodation chamber 1012a is formed by the mounting surface 1011a, the first inner surface 1012b, and the second inner surface 1013a.

The housing 1012 and the lid 1013 are made of a material that reflects radio waves (hereinafter, referred to as a radio wave reflecting material) or a material that absorbs radio waves (hereinafter, referred to as a radio wave absorbing material). 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 waves 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 second drive mechanism 1016 is near the rotation axis of the lid body 1013. The position of the second drive mechanism 1016 is not limited to this. The second drive mechanism 1016 moves the lid body 1013. The second drive mechanism 1016 shifts the lid body 1013 from the open state to the closed state when the lid body 1013 is in the open state. The second drive mechanism 1016 may include a mechanism for moving the lid body 1013. The configuration of the second drive mechanism 1016 is mechanical or the like, but is not particularly limited. For example, the second drive mechanism 1016 is a mechanism for moving the lid body 1013 by a motor.

FIG. 3 is a cross-sectional view taken along the line XX of the reading device 101 in FIG. The lid body 1013 is in the closed state. The storage chamber 1012a houses a basket 202 containing a plurality of products 201. Each product 201 has an RFID tag 203 attached to it.

The mounting table 1011 includes a surface 1011b facing the mounting surface 1011a. Inside the housing 1012, there is a space formed by the surface 1011b of the mounting table 1011 and the first inner surface 1012b of the housing 1012. This space in the housing 1012 is formed on the side opposite to the storage chamber 1012a with the mounting table 1011 in between.

As shown in FIG. 3, the reading device 101 includes an antenna 1017. The antenna 1017 is a planar RFID antenna. The antenna 1017 radiates (also referred to as emission) radio waves in the UHF band or the like when electric power is supplied. The antenna 1017 radiates radio waves toward the inside of the accommodation chamber 1012a.

The antenna 1017 is on the surface 1011b side of the mounting table 1011 facing the mounting surface 1011a. The antenna 1017 is located at a position farther from the accommodation chamber 1012a than the mounting surface 1011a in the direction orthogonal to the mounting surface 1011a. The antenna 1017 radiates radio waves toward the inside of the accommodation chamber 1012a. As described above, since the mounting table 1011 is made of a material having radio wave transmission, the radio waves radiated by the antenna 1017 pass through the mounting table 1011 and are attached to each product 201 housed in the storage chamber 1012a. It reaches each RFID tag 203 that is attached. The reading device 101 may include a drive mechanism for moving the position of the antenna 1017. The reading device 101 may include two or more antennas.

FIG. 4 is a block diagram showing a configuration of a control system of the POS device 1 as an example. In addition to the above-mentioned elements, the POS device 1 includes a control unit 11, a storage unit 12, an input unit 13, a card reading unit 14, a coin insertion processing unit 15, a bill insertion / removal processing unit 16, a coin ejection processing unit 17, and a printer 18. It includes a communication I / F (interface) 19, a reader / writer 1018, and a third detection unit 1019.

The control unit 11 is connected to each unit of the POS device 1. The control unit 11 controls the operation of each unit. For example, the control unit 11 is a CPU (Central Processing Unit).
The storage unit 12 can include a ROM (Read Only Memory) that stores a program executed by the control unit 11. The storage unit 12 may also include a RAM (Random Access Memory) that temporarily stores data when the control unit 11 executes a program. The storage unit 12 may also include an HDD (Hard Disk Drive) that stores various types of data.

The input unit 13 is an element capable of inputting or selecting various information by a customer who uses the POS device 1. For example, the input unit 13 is a touch panel integrated with the display unit 107.
The card reading unit 14 reads information from the credit card inserted at the card insertion slot 102.

The coin insertion processing unit 15 calculates and processes the amount of coins that the customer has inserted into the coin insertion slot 105 at the time of settlement processing.
The banknote entry / exit processing unit 16 calculates and processes the amount of banknotes that the customer has deposited in the banknote entry / exit 104 at the time of settlement processing. The bill entry / exit processing unit 16 processes the discharge of bills to be returned as fishing at the time of settlement processing.
The coin discharge processing unit 17 processes the discharge of coins to be returned as fishing at the time of settlement processing to the coin outlet 106.

The printer 18 issues a receipt at the time of payment processing, and processes the discharge of the receipt from the receipt issuing port 103.
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 radio waves from the antenna 1017 for reading the information stored in the RFID tag 203. 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 to the antenna 1017 for writing information (for example, the above-mentioned payment end information) on the RFID tag 203. The reader / writer 1018 radiates radio waves 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 storage chamber 1012a. For example, the reading 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 uses the first drive mechanism 1015 to control the lid body 1013 so as to transition from the closed state to the open state. The open / close control unit 112 uses the second drive mechanism 1016 to control the lid body 1013 so as to transition from the open state to the closed state.

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 which is an example of the 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 the 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 accommodation chamber 1012a (Act1003, Yes), the open / close control unit 112 controls to close the lid body 1013 (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 storage chamber 1012a (Act1005). In Act 1005, 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 products 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 settlement end information in each RFID tag after the settlement process is completed. When 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 Act 1007, after the settlement processing unit 113 finishes the settlement process, 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 prompt 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 removing the product. The control unit 11 may control the display unit 107 to display information prompting the product to be taken out 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 to close the lid body 1013 (Act1009). That is, in Act1009, after the settlement processing unit 113 finishes the settlement processing, the second drive mechanism 1016 covers the second drive mechanism 1016 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 1013 after a certain period of time has elapsed after the treatment of Act 1007. 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 Act1009 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. The fixed time can be set arbitrarily. 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 stops detecting 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 no longer detects 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 body 1013 from the closed state to the open state. Therefore, the customer in the vicinity of the lid body 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 a person who wants to use it is in the vicinity of the POS device 1.
