  In recent years, a product sales data processing apparatus that can be driven by a battery has been known. Such a merchandise sales data processing apparatus can be used even in places where power cannot be easily secured, such as outdoors. However, it is difficult to drive for a long time with a battery used in a merchandise sales data processing apparatus. For this reason, further power saving is demanded in the merchandise sales data processing apparatus.

  The problem to be solved by the present invention is to provide a merchandise sales data processing apparatus capable of further saving power in a merchandise sales data processing apparatus in which a display is rotatably connected to a main body.

In one embodiment, the merchandise sales data processing apparatus includes a main body, a display unit, an acceleration sensor, and a control unit. The display unit has a display surface for displaying an image , the first rotation position where the display surface faces the operator side with respect to the main body, and the display surface other than the first rotation position on the customer side. It is supported so as to be rotatable between the second rotational position facing . The acceleration sensor is provided on the display unit, for detecting whether there in one display unit in accordance with a change in acceleration generated in the display unit of the first rotational position and a rotational position other than a rotational position of the first . The control unit is configured such that the luminance when the rotation angle of the display unit is closer to the first rotation position side than the luminance when the rotation angle of the display unit is closer to the second rotation position side. The brightness of the display surface is controlled to an optimum brightness according to the rotation angle of the display unit so as to be relatively low .

It is an external appearance perspective view of the POS terminal concerning this embodiment. It is a figure for demonstrating rotation of the display with respect to a main body. It is a block diagram showing the system configuration example of the POS terminal which concerns on this embodiment. It is a flowchart which shows the registration process controlled by CPU of a POS terminal.

Hereinafter, an embodiment of a merchandise sales data processing apparatus will be described using, for example, a POS terminal used in a store or outdoors.
FIG. 1 is an external perspective view of a POS terminal according to the present embodiment. As shown in FIG. 1, the POS terminal 1 includes a main body 10 in which each constituent member described later is accommodated, and a display 12 disposed on the main body 10. In the present embodiment, the display 12 is supported by the main body 10 via, for example, a hinge so as to be rotatable within a range of approximately 90 degrees with respect to the main body 10. With such a configuration, the display 12 is rotated around the hinge 10a between the first rotation position shown in FIG. 2A and the second rotation position shown in FIG. 2B.

  Here, the first rotation position is a position where the display 12 contacts the upper surface of the main body 10. As shown in FIG. 2A, the upper surface of the main body 10 is configured to have an inclination with respect to the ground surface. Therefore, when the display 12 is in the first rotation position, the display 12 is also inclined with respect to the ground surface. The state in which the display 12 is in the first rotational position is a state in which it is assumed that the display surface of the display 12 is viewed by an operator (a store clerk). For this reason, an operator screen may be displayed in a state where the display 12 is in the first rotation position.

  On the other hand, the second rotation position as an example of the rotation position other than the first rotation position is a position where the display 12 is separated from the upper surface of the main body 10 as shown in FIG. When the display 12 is in the second rotational position, the display 12 is substantially perpendicular to the ground surface. The state in which the display 12 is in the second rotational position is a state assuming that the display surface of the display 12 is viewed by the customer. For this reason, when the display 12 is in the second rotation position, a customer screen may be displayed.

Here, whether the display 12 is in the first rotational position or a rotational position other than the first rotational position is detected by, for example, an acceleration sensor 19 provided in the display 12. The acceleration sensor 19 is configured to show gravitational acceleration (about 9.8 m / s ² ) in a state where the display 12 is at the first rotational position shown in FIG. From this state, when the display 12 reaches the second rotational position shown in FIG. 2B, the output of the acceleration sensor 19 changes from the gravitational acceleration. By this change in acceleration, it is possible to detect whether the display 12 is in the first rotational position or a rotational position other than the first rotational position. Note that the rotation angle θ of the display 12 with respect to the upper surface of the main body 10 can be detected from the output of the acceleration sensor 19.

  FIG. 3 is a block diagram illustrating a system configuration example of the POS terminal according to the present embodiment. As shown in FIG. 3, the main body 10 includes a power supply circuit 101, a charge / discharge circuit 103, a battery 105, a power switch 107, a CPU 109, a clock oscillator 109c, an input / output (I / O) controller 111, A ROM (Read Only Memory) 113, a RAM (Random Access Memory) 115, a communication interface (I / F) 117, an HDD (Hard Disc Drive) 119, and a printer 121 are included. In addition, as shown in FIG. 3, the main body 10 has a drawer 16 for accommodating cash and the like, and a customer display 17 for displaying merchandise sales data, a total amount related to transactions, and the like to the shopper. And a scanner 18 for reading a barcode or the like attached to the product.

  The display 12 includes a touch panel 12-1, an LCD (Liquid Crystal Display) 12-2, and an acceleration sensor 19.

  The power switch 107 is a main power switch of the POS terminal 1. The power switch 107 connects the charge / discharge circuit 103 and the power circuit 101 in the ON state. A battery 105 is connected to the charge / discharge circuit 103. The battery 105 is a battery for operating the POS terminal 1 without using a commercial power source. The battery 105 functions as a driving power source used when it is difficult to secure a commercial power source such as outdoors. Further, the charge / discharge circuit 103 is configured to be connected to a commercial power supply. The charging / discharging circuit 103 supplies the power of the commercial power source to the power source circuit 101 when the power switch 107 is turned on when the commercial power source is used. The charging / discharging circuit 103 charges the battery 105 by applying a commercial power supply voltage to the battery 105 when the battery 105 is charged, and supplies the discharged power of the charged battery 105 to the power circuit 101 when the battery 105 is discharged. . When the power switch 107 is turned on and power is supplied from the charge / discharge circuit 103, the power supply circuit 101 applies the voltage of the battery 105 or the commercial power supply to each part of the POS terminal 1 to drive each part of the main body 10. To supply power for.

  The CPU 109 is a control unit that comprehensively controls each unit of the POS terminal 1. The CPU 109 operates by reading out various programs stored in the ROM 113 and the HDD 119 and executing them. The clock oscillator 109c supplies a clock signal to the CPU 109. The clock signal is supplied via a line CLK for transmitting the clock signal, not the bus used for transmission / reception of the control signal. The CPU 109 operates in synchronization with the clock signal supplied from the clock oscillator 109c.

The ROM 113 stores various programs executed by the CPU 109, various data tables, and the like. Here, the ROM 113 of the present embodiment stores a table in which the rotation angle of the display 12 and the luminance of the display surface of the display 12 (luminance of the backlight 12b) are associated as one of various data tables. Here, in the present embodiment, the luminance when the rotation angle θ of the display 12 is a rotation angle close to the customer side is relatively higher than the luminance when the rotation angle θ of the display 12 is a rotation angle close to the operator side. The rotation angle θ and the luminance are associated with each other so as to be higher . This table may be stored in the HDD 119 or the light control circuit 12m described later.

  The RAM 115 is a memory that temporarily stores data and programs when the CPU 109 executes various programs. The RAM 115 includes at least a transaction memory for storing product sales data indicating a sales record of products, and a display data memory for storing various screen display data to be displayed on the display 12 or the customer display 17.

  The I / O controller 111 is a controller connected to the CPU 109 and each I / O device via a data bus. The CPU 109 controls the entire system of the POS terminal 1 via the I / O controller 111. The communication I / F 117 is a communication interface for controlling wireless communication / wired communication with the host server or management center of the POS terminal 1.

  The HDD 119 is a storage medium that stores various types of information, and stores, for example, product data files. The product data file is a data file in which product data such as a product name and a unit price is preset in correspondence with, for example, a product identification code for identifying each product (hereinafter abbreviated as a product code). When the product code is input to the POS terminal 1, the CPU 109 retrieves the product data file stored in the HDD 119, takes in the product data corresponding to the product code, and registers the product sales data based on the product data. Execute. The HDD 119 may store, for example, sales data for each accounting described later, in addition to the above-described product data file.

  The product code is input by an operator called a cashier who operates the POS terminal 1 by reading a barcode with the scanner 18, for example, or inputting it using the touch panel 12-1 or a keyboard (not shown). Since the product code input method is not related to the feature of the present embodiment, detailed description thereof is omitted here.

  The touch panel 12-1 is, for example, a resistive film type touch panel. The touch panel 12-1 outputs an electrical signal corresponding to a position where the user performs a touch operation touched with a fingertip or a touch pen. The I / O controller 111 calculates the coordinates of the contact position based on the electrical signal output from the touch panel 12-1, and notifies the CPU 109 of the calculated coordinates.

  The LCD 12-2 is a display unit made up of a liquid crystal display and has a display surface for displaying an image. The LCD 12-2 includes a backlight 12b and a light control circuit 12m. The backlight 12b is disposed on the back surface of the display surface of the liquid crystal display, and illuminates the display surface from the back surface side. Based on the control signal received from the CPU 109, the dimming circuit 12m controls the level of brightness of the backlight 12b and lighting / extinguishing. The luminance control by the dimming circuit 12m is performed according to the table stored in the ROM 113 described above.

  The acceleration sensor 19 as an example of the detection unit is an acceleration sensor whose orientation is set so as to output gravitational acceleration when the display 12 is in the first rotation position. The CPU 109 detects the rotation angle θ of the display 12 from the acceleration change from the gravitational acceleration. Note that the output of the acceleration sensor 19 is notified to the CPU 109 via the I / O controller 111.

  The operation of the POS terminal 1 according to the present embodiment in merchandise sales will be described with reference to FIG. FIG. 4 is a flowchart showing a registration process controlled by the CPU 109 of the POS terminal 1. This registration process is started when the cashier operates the touch panel 12-1 of the POS terminal 1, for example, and selects a product registration service.

  In S <b> 1, the CPU 109 detects the rotation angle θ of the display 12 from the output of the acceleration sensor 19. In S2, the CPU 109 determines whether or not the rotation angle θ of the display 12 has changed (that is, whether or not the acceleration has changed). If it is determined in S2 that the rotation angle θ of the display 12 has not changed (NO), the CPU 109 shifts the process to S6.

  When it is determined in S2 that the rotation angle θ of the display 12 has changed (YES), in S3, the CPU 109 sets the rotation angle θ of the display 12 to the rotation angle close to the customer side, that is, the second rotation position. It is determined whether or not the rotation angle is close. Whether or not the rotation angle is close to the second rotation position is determined by determining whether or not the rotation angle θ exceeds a predetermined threshold, for example.

In S3, when it is determined that the rotation angle θ of the display 12 is a rotation angle close to the customer side (YES), in S4, the CPU 109 instructs the dimming circuit 12m to control the luminance of the backlight 12b. Output. As described above, the ROM 113 stores a table in which the rotation angle θ of the display 12 is associated with the luminance of the display surface of the display 12 (the luminance of the backlight 12b). The CPU 109 reads this table from the ROM 113, and outputs an instruction value for luminance optimally set according to the rotation angle θ to the dimming circuit 12m. In the present embodiment, the luminance when the rotation angle θ of the display 12 is a rotation angle close to the customer side is relatively higher than the luminance when the rotation angle θ of the display 12 is a rotation angle close to the operator side. Thus, the rotation angle θ and the luminance are associated with each other. Therefore, in S4, the luminance of the backlight 12b is relatively increased by the dimming circuit 12m. Actually, it is preferable to turn on the backlight 12b with the optimum luminance corresponding to the rotation angle θ while relatively increasing the luminance of the backlight 12b.

  In addition, when the position of the display 12 is switched from the first rotation position to the second rotation position, the image that has been displayed on the display surface of the display 12 upside down is reversed. For this reason, when it is determined that the rotation angle θ has changed, it is preferable that the image being displayed on the display 12 is turned upside down.

In S3, when it is determined that the rotation angle θ of the display 12 is not a rotation angle close to the customer side (NO), in S5, the CPU 109 outputs an instruction to the dimming circuit 12m so as to control the luminance of the backlight 12b. To do. As described above, in the present embodiment, the luminance when the rotation angle θ of the display 12 is closer to the customer side than the luminance when the rotation angle θ of the display 12 is closer to the operator side. The rotation angle θ and the luminance are associated with each other so that the direction becomes relatively high . Therefore, in S5, the luminance of the backlight 12b is relatively lowered by the dimming circuit 12m. Actually, it is preferable to turn on the backlight 12b with an optimum luminance corresponding to the rotation angle θ while relatively reducing the luminance of the backlight 12b.

  After S4 or S5, the CPU 109 shifts the process to S6. In S6, the CPU 109 determines whether an input has been made. Here, “input” means, for example, that the touch panel 12-1 or the scanner 18 is operated by the cashier. If it is determined in S6 that no input has been made (NO), that is, if the cashier is not operating the POS terminal 1, the CPU 109 returns the process to S1. That is, the luminance control of the display surface of the display 12 according to the rotation angle θ is repeated until an input is made.

  If it is determined in S6 that an input has been made (YES), in S7, the CPU 109 determines whether or not a product code has been input. When determining in S7 that the product code has not been input (NO), the CPU 109 returns the process to S7. That is, the process is in a standby state until a product code is input.

  If it is determined in S7 that the product code has been input (YES), in S8, the CPU 109 searches the product data file stored in the HDD 119 for the input product code and stores it corresponding to the product code. The product information such as the product name and unit price is detected and imported. In S9, the CPU 109 generates merchandise sales data based on the merchandise information acquired in S8 and the number of sales points input by the cashier using the touch panel 12-1, for example, and registers the merchandise sales data in the transaction memory of the RAM 115. Here, the product sales data includes, for example, at least a product code, a sales score, and a sales amount (unit price × sales score) of the sales product. In S10, the CPU 109 displays the product sales data registered in S9 on the display 12 and the customer display 17.

  In S11, the CPU 109 determines whether or not a subtotal key has been input, that is, whether or not a “subtotal instruction” has been performed. Here, the “subtotal instruction” is an instruction made by the cashier touching a “subtotal key” displayed on the display 12, for example, and is an “instruction for closing the transaction”. If it is determined in S11 that there is no subtotal key input (NO), that is, if the “subtotal instruction” is not made, the CPU 109 returns the process to S7. At this time, the CPU 109 waits for input of the next product code.

  If it is determined in S11 that there is a subtotal key input (YES), that is, if a "subtotal instruction" is made, in S12, the CPU 109 calculates the total amount (product price) related to the transaction and displays it. 12 and the customer display 17. In S13, the CPU 109 determines whether or not the “current total key” has been input, that is, whether or not the “current total operation” has been performed. Here, the “actual operation” is an operation performed by the cashier touching an “actual key” displayed on the display 12, for example. Operation ”. If it is determined in S13 that the “current key” has not been input (NO), the CPU 109 returns the process to S13. That is, the process enters a standby state waiting for payment.

  If it is determined in S13 that the “actual key” has been entered (YES), in S14, the CPU 109 subtracts the “total amount related to the transaction (product price)” from the “cash amount from the customer”. The “change amount” is calculated and displayed on the display 12 and the customer display 17. In step S15, the CPU 109 transmits a receipt print command for causing the printer 121 to print a receipt. As a result, the printer 121 starts printing a receipt describing the detailed information of the transaction.

  In S <b> 16, the CPU 109 transmits a drawer release command to the drawer 16. The cashier accommodates the “deposit” in the opened drawer 16 and takes out the “change”. In S17, the CPU 109 transmits sales data indicating detailed information of the transaction to a host server (not shown) via the communication I / F 117.

  In step S <b> 18, the CPU 109 determines whether a signal indicating that the receipt printing has been completed is input from the printer 121. If it is determined in S18 that there is no input to end printing (NO), the CPU 109 returns the process to S18. That is, the process is in a standby state until the printing is completed.

  If it is determined in S18 that there is an input to end printing (YES), in S19, the CPU 109 determines whether or not an instruction to end the main registration process has been input. If it is determined in S19 that the end instruction has not been input (NO), the CPU 109 returns the process to S1. In this case, for example, until the next customer's response by the cashier, the process enters a standby state in S1. If it is determined in S19 that an end instruction has been input (YES), the CPU 109 ends the process.

  As described above, according to the present embodiment, it is possible to save power by relatively reducing the luminance of the display surface when the display 12 is in the first rotation position on the operator side. It is. On the other hand, when the display 12 is at a rotational position other than the first rotational position on the customer side (second rotational position in the example), the brightness of the display surface is relatively increased, thereby displaying a bright and clear display. It is possible. As described above, according to the present embodiment, it is possible to perform display with the optimum luminance corresponding to the rotation angle of the display 12 while saving power. Therefore, it is possible to drive the POS terminal 1 for a longer time when the battery is driven.

  Here, in this embodiment, an acceleration sensor is shown as an example of the detection unit, but an angular velocity sensor may be used as the detection unit. In addition, the rotation amount of the hinge 10a may be detected using an encoder or the like.

  In the present embodiment, a liquid crystal display (LCD) is shown as an example of the display unit. However, various displays that can change the luminance of the display surface such as an organic EL display can be used as the display unit.

  In the above embodiment, a control program for realizing the functions of the invention is recorded in advance in the ROM 113 which is a program storage unit in the apparatus. However, the present invention is not limited to this, and a similar program may be downloaded from the network to the apparatus. Alternatively, a similar program recorded on the recording medium may be installed in the apparatus. The recording medium may be in any form as long as it can store a program such as a CD-ROM or a memory card and can be read by the apparatus. Further, the function obtained by installing or downloading the program may be realized in cooperation with an OS (operating system) inside the apparatus.

  In addition, although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
