[0013] The embodiments of the present disclosure will be described with reference to the drawings. However, the configuration and operation of the cash register in the embodiments are not limited to those described in the drawings.

[0014] First Embodiment FIG. 1 is a block diagram showing an example of the configuration of a cash register 10. The cash register 10 includes a display 20, a display movement mechanism 21, a camera 30, and a display information processor 40. The display information processor 40 includes a store clerk identification unit 110, a setting acquisition unit 120, and a display setting unit 130. The cash register 10 is, for example, a Point of Sales (POS) register. That is, a store clerk operates the cash register 10 to perform a transaction with a customer. Therefore, the cash register 10 may include other components in addition to the components shown in FIG. 1. For example, the cash register 10 may include a keyboard operated by the store clerk in the transaction, a cash drawer for storing bills and coins, and a receipt printer. However, the cash register 10 is not limited to a POS register and may be another device. For example, the cash register 10 may be a register that does not include advanced functions such as POS functions, but has simple functions such as money transfer.

[0015] The display 20 displays information such as the name, number, and amount of merchandise referred to by a store clerk operating the cash register 10. The display 20 is provided, for example, on the top of the cash register 10. However, the display 20 is not limited to being provided on the top of the cash register 10 and may be provided in other locations. The display 20 may be provided integrally with the cash register 10 or may be provided as a separate device connected to the cash register 10 by a cable. The display 20 may have an input function such as a touch panel. In addition to the display 20, the cash register 10 may have other displays such as a customer display for providing information such as the bill amount and change to a customer.

[0016] The display unit moving mechanism 21 changes at least one of the position and the orientation of the display unit 20. The position of the display unit 20 is the position of the display unit 20 relative to a reference point or reference plane in the cash register 10. For example, the position of the display unit 20 is the height of the top end face of the display unit 20 when the bottom face of the cash register 10 is taken as the reference plane. The reference plane for the height is not limited to the bottom face of the cash register 10, and may be another face, such as the face on which the display unit 20 is installed. The position of the display unit 20 changed by the display unit moving mechanism 21 is not limited to the position in the height direction, and may be the position in the horizontal direction. For example, the display unit moving mechanism 21 may change the position of the display unit 20 by changing the position of the left end face of the display unit 20 relative to the left end face of the cash register 10, or the position of the right end face of the display unit 20 relative to the right end face of the cash register 10. Alternatively, the display moving mechanism 21 may change the position of the display 20 by changing the position of the front end face of the display 20 relative to the front end face of the cash register 10, or the position of the rear end face of the display 20 relative to the rear end face of the cash register 10. The display moving mechanism 21 may change multiple positions of the display 20, such as height, front-to-back position, and left-to-right position.

[0017] The orientation of the display 20 is the orientation of a specific surface, such as a liquid crystal display, that displays information on the display 20. For example, the orientation of the display 20 is the horizontal angle and elevation angle of a liquid crystal display provided on the display 20. The horizontal angle is, for example, the horizontal angle of the liquid crystal display of the display 20 relative to the operation surface of the cash register 10. However, the reference direction of the horizontal angle is not limited to the direction of the operation surface of the cash register 10, and may be another direction. The elevation angle is, for example, the angle of the liquid crystal display of the display 20 relative to the horizontal plane. However, the orientation of the display 20 may be an angle different from the above.

[0018] The display unit moving mechanism 21 changes at least one of the position and the orientation of the display unit 20. For example, the display unit moving mechanism 21 includes a drive unit, a sensor, and a control unit. The drive unit is, for example, a combination of a motor and a gear. The sensor is, for example, a potentiometer and an encoder. The control unit includes a computer and a memory, and controls the operation of the drive unit using information from the sensor. For example, when setting information for setting the position of the display unit 20 is acquired, the control unit controls the operation of the drive unit using information from the sensor to change the position of the display unit 20 so that the position is the position of the acquired setting information. The control unit may operate in the same manner when setting information for setting the orientation is acquired. However, the configuration of the display unit moving mechanism 21 is not limited to the above. For example, the control unit of the display unit moving mechanism 21, the drive unit, and the sensor may be physically separated. For example, the drive unit and the sensor may be provided on a part that supports the display unit 20, such as a support or arm of the display unit 20, and the control unit may be provided inside the display unit 20. However, the position and configuration of the display unit moving mechanism 21 are not limited to those described above, and may be appropriately determined by a designer in accordance with the mechanisms of the drive unit, sensor, and control unit.

[0019] FIG. 2 is a diagram showing an example of the display 20 and the display movement mechanism 21. FIG. 2 shows the display 20, the display movement mechanism 21, the support 22, the arm 23, and the base 24. In FIG. 2, the main body of the cash register 10 is omitted for ease of viewing. The base 24 is provided on a fixed member such as the frame of the cash register 10. The support 22 is provided on the base 24 and configured to support the display movement mechanism 21. The support 22 also serves as a guide when the display movement mechanism 21 changes the display 20 in the height direction. The arm 23 is provided on the display movement mechanism 21 and supports the display 20. In other words, the display movement mechanism 21 is supported by the base 24 and the support 22, and supports the display 20 via the arm 23.

[0020] Fig. 3 is a diagram showing an example of changing the height of the display unit 20. The upper diagram of Fig. 3 is a diagram showing an example of a case where the display unit 20 is in a high position. The lower diagram of Fig. 3 is a diagram showing an example of a case where the display unit 20 is in a low position. In this way, the display unit moving mechanism 21 shown in Fig. 3 moves up and down along the support column 22 to change the height of the display unit 20.

[0021] FIG. 4 is a diagram showing an example of changing the horizontal angle of the display unit 20. The left diagram of FIG. 4 is a diagram showing an example of the case where the display unit 20 is rotated leftward. The center diagram of FIG. 4 is a diagram showing an example of the case where the display unit 20 is located in the center of the rotation range of the horizontal angle, that is, facing forward. The right diagram of FIG. 4 is a diagram showing an example of the case where the display unit 20 is rotated rightward. In this way, the display unit moving mechanism 21 shown in FIG. 4 changes the horizontal angle of the display unit 20 around the support column 22.

[0022] FIG. 5 is a diagram showing an example of a change in the elevation angle of the display unit 20. The left diagram of FIG. 5 is a diagram showing an example of a case where the display unit 20 is rotated upward relative to a horizontal plane such as a stand. The center diagram of FIG. 5 is a diagram showing an example of a case where the display unit 20 is located in the center, that is, a case where the display unit 20 is perpendicular to a horizontal plane such as a stand. The right diagram of FIG. 5 is a diagram showing an example of a case where the display unit 20 is rotated downward relative to a horizontal plane such as a stand. In this way, the display unit moving mechanism 21 shown in FIG. 5 changes the elevation angle of the display unit 20 by rotating the arm 23 in the vertical direction.

[0023] The photographing device 30 takes a facial image of the store clerk operating the cash register 10. The photographing device 30 is, for example, a camera provided on the top of the cash register 10 or on the display 20. However, the photographing device 30 may be provided in another position, such as on the operation surface on which the keys for operating the cash register 10 are provided.

[0024] The store clerk identification unit 110 identifies the store clerk using the face image of the store clerk captured by the photographing device 30. For example, assume that the server of the POS system associates and stores the face image of the store clerk with the identifier of the store clerk. In this case, the store clerk identification unit 110 sends the face image captured by the photographing device 30 to the server. Then, the store clerk identification unit 110 acquires from the server information of the store clerk associated with the face image of the store clerk captured by the photographing device 30, such as the identifier of the store clerk determined by the server using face recognition or the like. However, the store clerk identification unit 110 is not limited to the server of the POS system, and may use other devices as long as it can identify the store clerk. Alternatively, the store clerk identification unit 110 may identify the identifier of the store clerk stored in advance based on face image recognition using the acquired face image.

[0025] The setting acquisition unit 120 acquires setting information for setting at least one of the position and orientation of the display 20 according to the identified store clerk. For example, it is assumed that the server of the POS system stores setting information for at least one of the position and orientation of the display 20 according to the store clerk in association with the identifier of the store clerk. In this case, the setting acquisition unit 120 sends the identifier of the identified store clerk to the server. Then, the setting acquisition unit 120 acquires setting information for setting at least one of the position and orientation of the display 20 according to the store clerk from the server. However, the setting acquisition unit 120 is not limited to acquiring setting information from the server of the POS system, and may acquire setting information from another device.

[0026] The setting acquisition unit 120 may acquire information on other settings of the display unit 20 in addition to the setting information for setting at least one of the position and orientation of the display unit 20 using the display unit moving mechanism 21. For example, the setting acquisition unit 120 may acquire display setting information that specifies settings according to the store clerk for the display of information to be referenced by the store clerk and displayed on the display unit 20 as the other settings of the display unit 20. The display setting information is information that specifies at least one of physical settings and software settings for display on the display unit 20. Examples of the physical display setting information include, but are not limited to, brightness, contrast, and background color. Examples of the software settings include, but are not limited to, character size, font, and character color.

[0027] The installation position and size of the display 20 may differ for each model of the cash register 10. Alternatively, the stand or desk on which the cash register 10 is installed may differ depending on the installation location in the store or for each store. In other words, the position and orientation of the display 20 depending on the clerk may differ depending on the store, the installation location, and the cash register 10. Therefore, the setting acquisition unit 120 may acquire setting information using information on the store where the cash register 10 is installed, information on the installation location, and information on the cash register 10. For example, the above-mentioned POS server may store setting information for setting at least one of the position and orientation of the display 20 in association with at least one of the store information, the installation location information, and the cash register 10 information in addition to the identifier of the clerk. Then, the setting acquisition unit 120 may acquire setting information for setting at least one of the position and orientation of the display 20 using the identifier of the clerk and at least one of the store information, the installation location information, and the cash register 10 information. The store information may be, for example, but is not limited to, a store name, a store identifier, or a store number. The installation location information may be, for example, but is not limited to, an installation location identifier or number. The cash register 10 information may be, for example, but is not limited to, an identifier for individually identifying the cash register 10 or the model name of the cash register 10. The model name may be, for example, but is not limited to, a manufacturer name, model name, model number, or a combination thereof.

[0028] The display setting unit 130 uses the setting information to set at least one of the position and orientation of the display 20 to the display movement mechanism 21. For example, the display setting unit 130 may output the setting information acquired by the setting acquisition unit 120 to the display movement mechanism 21. In this case, the display movement mechanism 21 moves the display 20 so that at least one of the position and orientation of the display 20 becomes at least one of the position and orientation indicated in the setting information. The display setting unit 130 may perform an operation different from the above. For example, the display setting unit 130 may operate using a difference between at least one of the position and orientation set using the setting information and at least one of the current position and orientation. An example of the operation in this case will be described. When acquiring the setting information from the setting acquisition unit 120, the display setting unit 130 acquires at least one of the current position and orientation of the display 20 from the sensor of the display movement mechanism 21. Then, the display setting unit 130 calculates a difference between at least one of the current position and orientation and at least one of the position and orientation acquired by the setting acquisition unit 120. Then, the display setting unit 130 may output the difference in at least one of the position and the orientation to the display movement mechanism 21. In this case, the display movement mechanism 21 moves the display 20 so as to correspond to the acquired difference.

[0029] When the setting acquisition unit 120 has acquired display setting information for the display unit 20 corresponding to the store clerk, the display setting unit 130 may set the display of the display unit 20 based on the display setting information. For example, the display setting unit 130 may output the display setting information to the display unit 20. In this case, the display unit 20 changes the display based on the display setting information acquired from the display setting unit 130. For example, the display unit 20 changes at least one setting of brightness, contrast, character size, character color, and background color based on the display setting information.

[0030] 6 is a flow diagram showing an example of the operation of the cash register 10. Prior to the operation, the server pre-stores a facial image of the clerk and setting information for setting at least one of the position and orientation of the display 20 according to the clerk. For example, when a store manager determines a clerk for the cash register 10, the clerk checks in advance the position and orientation of the display 20 suitable for him / her, and associates the position and orientation of the display 20 suitable for him / her with his / her facial image and stores them in the server.

[0031] The photographing device 30 photographs a face image of the store clerk (step S201). For example, the photographing device 30 captures the face image of the store clerk when the cash register 10 is powered on. Alternatively, when the store clerk causes the cash register 10 to read information on an employee ID card when starting to operate the cash register 10, the photographing device 30 photographs a face image of the store clerk. The store clerk identification unit 110 identifies the store clerk using the face image photographed by the photographing device 30 (step S202). For example, the store clerk identification unit 110 outputs the face image to a server and acquires the store clerk's identifier. If the cash register 10 uses face image authentication using a face image of the store clerk photographed by the photographing device 30 when starting operation, etc., the operations of steps S201 and S202 may be included in the operation of face image authentication.

[0032] The setting acquisition unit 120 acquires setting information for setting at least one of the position and orientation of the display 20 according to the identified store clerk using the face image of the store clerk (step S203). For example, the setting acquisition unit 120 outputs the store clerk's identifier to the server, and acquires from the server setting information for setting at least one of the position and orientation of the display 20 associated with the store clerk's face image.

[0033] The display setting unit 130 uses the setting information to set at least one of the position and orientation of the display 20 to the display movement mechanism 21 (step S204). For example, the display setting unit 130 outputs the setting information of the display 20 acquired by the setting acquisition unit 120 to the display movement mechanism 21. Then, the display movement mechanism 21 changes at least one of the position and orientation of the display 20 so that at least one of the position and orientation of the display 20 becomes at least one of the position and orientation included in the acquired setting information.

[0034] As described above, the cash register 10 includes a display 20, a display movement mechanism 21, a photographing device 30, a clerk identification unit 110, a setting acquisition unit 120, and a display setting unit 130. The display 20 displays information referred to by a clerk who operates the cash register 10. The display movement mechanism 21 changes at least one of the position and orientation of the display 20. The photographing device 30 photographs a facial image of the clerk. The clerk identification unit 110 identifies the clerk using the facial image of the clerk photographed by the photographing device 30. The setting acquisition unit 120 acquires setting information for setting at least one of the position and orientation of the display 20 according to the identified clerk. The display setting unit 130 causes the display movement mechanism 21 to set at least one of the position and orientation of the display using the setting information.

[0035] The clerk performs the work while referring to the information displayed on the display 20 of the cash register 10. Therefore, the position and orientation of the display 20 affect the visibility of the information displayed on the display 20 from the clerk. Therefore, the clerk identification unit 110 identifies the clerk using the face image of the clerk photographed by the photographing device 30. The setting acquisition unit 120 acquires setting information for setting at least one of the position and orientation of the display 20 according to the identified clerk. Then, the display setting unit 130 causes the display moving mechanism 21 to set at least one of the position and orientation of the display 20 using the setting information. In detail, for example, the display setting unit 130 outputs the setting information for setting at least one of the position and orientation of the display 20 acquired by the setting acquisition unit 120 to the display moving mechanism 21. Then, the display moving mechanism 21 changes at least one of the position and orientation of the display 20 based on the acquired setting information. The position and orientation of the display 20 set in this manner are appropriate settings for the clerk. That is, the display 20 is appropriately set to improve visibility for the store clerk who operates the cash register 10. Therefore, the store clerk can carry out the work while appropriately checking the information.

[0036] The cash register 10 may have a change in the clerk. In this case, the photographing device 30 may capture a facial image of the clerk. For example, when the clerk is changed and the new clerk reads his / her employee ID card into the cash register 10 to set the clerk's information, the photographing device 30 may capture a facial image of the clerk. The setting acquisition unit 120 then acquires setting information using the facial image of the new clerk. The display setting unit 130 then uses the setting information acquired by the setting acquisition unit 120 to set at least one of the position and orientation of the display 20 in the display moving mechanism 21. With this operation, the cash register 10 can set at least one of the position and orientation of the display 20 corresponding to the new clerk even when the clerk is changed. In this way, the cash register 10 sets at least one of the position and orientation of the display 20 to improve the visibility of the display 20, even if the new clerk does not set the position and orientation of the display 20.

[0037] The setting acquisition unit 120 acquires setting information from another device such as a server. Then, the display setting unit 130 sets at least one of the position and orientation of the display 20 in the display moving mechanism 21 using the setting information acquired by the setting acquisition unit 120. Therefore, even if there are multiple cash registers 10 in a store, a store clerk can set at least one of the position and orientation of the display 20 by saving the setting information in another device such as a server, without having to set setting information for each of the multiple cash registers 10. In this way, the cash register 10 reduces the burden on store clerks.

[0038] Furthermore, the setting acquisition unit 120 may acquire display setting information of the display unit 20 as the setting information. Then, the display setting unit 130 may output the display setting information to the display unit 20. Then, the display unit 20 may set the display based on the acquired display setting information. In this case, the cash register 10 can set the display of the display unit 20 in addition to the position and orientation of the display unit 20 according to the store clerk. For example, the brightness and contrast of the display of the display unit 20 may differ depending on the store clerk. Alternatively, it is preferable that the size of the characters displayed on the display unit 20 be changed according to the eyesight of the store clerk. As described above, the setting acquisition unit 120 and the display setting unit 130 of the cash register 10 can set the display of the display unit 20 according to the store clerk. Therefore, the store clerk can use the display unit 20 with the display setting suitable for each store clerk.

[0039] There are cases where a store clerk wants to change at least one of the position and orientation of the display 20 after the display setting unit 130 has set at least one of the position and orientation of the display 20 using the setting information and the display moving mechanism 21. In this case, after setting at least one of the position and orientation of the display 20, the display setting unit 130 may operate to use at least one of the position and orientation of the display 20 newly set by the store clerk. An example of the operation in this case will be described.

[0040] After the display unit moving mechanism 21 sets at least one of the position and orientation of the display unit 20, the sensor of the display unit moving mechanism 21 detects a change in at least one of the position and orientation of the display unit 20. In this case, the display unit moving mechanism 21 outputs at least one of the changed position and orientation of the display unit 20 detected by the sensor to the display unit setting unit 130. When the display unit setting unit 130 acquires at least one of the changed position and orientation of the display unit 20 from the display unit moving mechanism 21, it changes at least one of the stored position and orientation of the display unit 20 according to the store clerk to at least one of the changed position and orientation of the display unit 20. For example, the display unit setting unit 130 may output at least one of the changed position and orientation of the display unit 20 acquired from the display unit moving mechanism 21 to a server, and request the server to change the setting information stored in the server to at least one of the output position and orientation of the display unit 20.

[0041] In some cases, it may be easier for a sensor such as an encoder to output the amount of change rather than the absolute amount. Therefore, the display setting unit 130 may obtain the amount of change in at least one of the position and orientation of the display unit 20 before and after the change from the display moving mechanism 21. In this case, the display setting unit 130 may change the setting information stored in the server using the amount of change. For example, the display setting unit 130 may output the amount of change in at least one of the position and orientation of the display unit 20 to the server, and request the server to correct the setting information using the amount of change and at least one of the position and orientation of the display unit 20 stored in the server.

[0042] When such an operation is performed, in the next operation, the setting acquisition unit 120 acquires at least one of the position and orientation after the change by the store clerk. Therefore, the display setting unit 130 sets at least one of the position and orientation of the display 20 to at least one of the position and orientation after the change. In other words, the display setting unit 130 can set the display 20 using at least one of the position and orientation changed by the store clerk. Therefore, the store clerk can use the display 20 with a more appropriate position and orientation. In the above description, the display setting unit 130 executes the operation of changing the setting information that sets at least one of the position and orientation of the display 20. However, the configuration of changing the setting information that sets at least one of the position and orientation of the display 20 is not limited to the display setting unit 130. For example, the setting acquisition unit 120 may acquire a difference from the display setting unit 130 and change the setting information that sets at least one of the position and orientation of the display 20.

[0043] <Hardware configuration> 7 is a block diagram showing an example of the hardware configuration of the cash register 10. The cash register 10 includes a display 20, a display movement mechanism 21, a camera 30, and a computer 60. The display 20, the display movement mechanism 21, and the camera 30 have the same configurations as those already described, so detailed descriptions are omitted. The computer 60 includes a processor 610, a read only memory (ROM) 620, a random access memory (RAM) 630, a storage device 640, an input / output interface 650, and a network interface 660.

[0044] The processor 610 reads a program from at least one of the ROM 620 and the storage device 640. The CPU 610 controls the RAM 630, the storage device 640, the input / output interface 650, and the network interface 660 based on the read program. The processor 610 controls these components to realize the functions of the store clerk identification unit 110, the setting acquisition unit 120, and the display setting unit 130. In this manner, the display information processing unit 40 including the store clerk identification unit 110, the setting acquisition unit 120, and the display setting unit 130 may be realized as a combination of hardware and software. The processor 610 may read a program recorded in a computer-readable manner on the recording medium 690 from a recording medium reading device (not shown) via the input / output interface 650. Alternatively, the processor 610 may receive a program from an external device (not shown) via the network interface 660, store the program in the RAM 630 or the storage device 640, and operate based on the stored program.

[0045] The ROM 620 stores programs and fixed data executed by the processor 610. The ROM 620 is, for example, a programmable ROM (P-ROM) or a flash ROM. The RAM 630 temporarily stores programs and data executed by the processor 610. The RAM 630 is, for example, a dynamic RAM (D-RAM). The storage device 640 stores data and programs that the computer 60 stores long-term. The storage device 640 may operate as a temporary storage device for the processor 610. The storage device 640 is, for example, a hard disk device or a solid state drive (SSD).

[0046] The ROM 620 and the storage device 640 are non-volatile (non-transitory) recording media. On the other hand, the RAM 630 is a volatile (transitory) recording medium. The processor 610 can operate based on the programs stored in the ROM 620, the storage device 640, and the RAM 630. In other words, the processor 610 can operate using either a non-volatile recording medium or a volatile recording medium.

[0047] The input / output interface 650 mediates the exchange of information between the display 20, the display movement mechanism 21, and the image capturing device 30 and the processor 610. The input / output interface 650 is, for example, but not limited to, a PCI (Peripheral Component Interconnect) bus card. The network interface 660 relays the exchange of data with an external device such as a server via a network. The network interface 660 is, for example, but not limited to, a local area network (LAN) card. The network interface 660 is not limited to a wired interface, and may be wireless.

[0048] <System> With reference to the drawings, a cash registration system 70 that uses a cash register 10 will be described. FIG. 8 is a block diagram showing an example of the configuration of the cash registration system 70. The cash registration system 70 includes the cash register 10 and a server 50. The cash register 10 and the server 50 are connected via a communication path such as an intranet, the Internet, or a telephone line network. In FIG. 8, the display movement mechanism 21 is located behind the display 20. The clerk identification unit 110, the setting acquisition unit 120, and the display setting unit 130 are realized by a processor or the like provided inside the cash register 10. Therefore, their display is omitted in FIG. 8.

[0049] Server 50 previously stores a face image of a store clerk, an identifier of the store clerk, and setting information for setting at least one of the position and orientation of the display according to the store clerk in association with each other. Then, when server 50 acquires a face image from store clerk identification unit 110, it outputs an identifier of the face image acquired using face image authentication to store clerk identification unit 110. Furthermore, when server 50 acquires an identifier of the store clerk from setting acquisition unit 120, it outputs at least one of the position and orientation of the display 20 associated with the acquired identifier to setting acquisition unit 120.

[0050] The camera 30 captures a facial image of the store clerk. The store clerk identification unit 110 identifies the store clerk using the facial image of the store clerk captured by the camera 30. For example, the store clerk identification unit 110 outputs the facial image to the server 50 and acquires an identifier of the store clerk from the server 50. The setting acquisition unit 120 then acquires setting information from the server 50 for setting at least one of the position and orientation of the display 20 according to the identified store clerk. The display setting unit 130 causes the display moving mechanism 21 to set at least one of the position and orientation of the display 20 using the setting information.
