Each embodiment will be described below with reference to the drawings.
In the following description, the same components are denoted by the same reference numerals, and redundant description will be given only when necessary.

(First embodiment)
[Main part configuration]
FIG. 1 is a block diagram showing a main configuration of a product sales data processing apparatus 1 according to this embodiment.
The merchandise sales data processing apparatus 1 includes a main body 2 placed on a cash register counter or the like in a store, and a keyboard 3 connected to the main body 2. The main body 2 and the keyboard 3 are connected via, for example, a USB cable.

  The main body 2 includes a CPU (Central Processing Unit) 10 that functions as a control center. A north bridge 11 is connected to the CPU 10, and a south bridge 12 is connected to the north bridge 11. The north bridge 11 and the south bridge 12 constitute a chip set.

  A memory 13 and a VGA (Video Graphic Array) chip 14 are connected to the north bridge 11. The memory 13 includes a ROM (Read Only Memory) that stores fixed data such as an operation program, and a RAM (Random Access Memory) that functions as a main memory of the merchandise sales data processing apparatus 1. The VGA chip 14 functions as a controller that controls a display 15 such as an LCD (Liquid Crystal Display).

  Connected to the south bridge 12 are a touch panel (T / P) controller 16, an audio controller 17, an HDD (Hard Disk Drive) 18, a system clock 19 (clocking means), a timer 20, and a keyboard 3.

  The touch panel controller 16 detects a voltage drop that occurs when the touch panel 21 provided on the display surface of the display 15 is touched, calculates the coordinates of the touch operation position, and outputs it to the CPU 10. The display 15 displays various screens including GUI parts that can be touched via the touch panel 21. The CPU 10 determines whether or not the operation position coordinates output from the touch panel controller 16 match the display position coordinates of the GUI component, and if they match, outputs the operation sound of the operated GUI component as audio. Command to controller 17.

  In addition to this operation sound output command, the CPU 10 instructs the audio controller 17 to output a scanning sound when a barcode is read by a barcode scanner (not shown), and when an error occurs. An error sound output is commanded, and when any pop-up is displayed on the display 22, a pop-up display sound output is commanded. These operation sounds, scanning sounds, error sounds, pop-up display sounds, and operation sounds output from the buzzer 32 described later are referred to as notification sounds in the following description.

  The audio controller 17 causes the speaker 22 to output a notification sound with a predetermined volume in response to the instruction of the notification sound output from the CPU 10. Further, when the sound collection by the microphone 23 is instructed by the CPU 10, the audio controller 17 takes in a signal output when the microphone 23 collects sound from the surroundings, generates sound data, and notifies the CPU 10. The speaker 22 and the microphone 23 are provided on the housing of the main body 2 toward the operator's standing position, for example, the side to which the display surface of the display 15 is directed.

The HDD 18 stores an OS (Operating System) file, various application files, various databases, and the like.
The system clock 19 measures the system date and time of the merchandise sales data processing apparatus 1. The timer 20 starts time counting at the timing when the operation start is commanded from the CPU 10, and stops the time counting at the timing when the operation stop is commanded.

  The keyboard 3 includes a mechanical operation unit including a numeric key, a PLU (Price Look Up) key, a subtotal key, a deposit / current total key, a person in charge key, and a keyboard (K / B) controller 30. , A buzzer controller 31, a buzzer 32, and a key switch (SW) 33. The keyboard controller 30 captures an input signal generated when the operation unit is operated and a mode signal output from the key switch 33 and sends it to the main body 2 and instructs the buzzer controller 31 to output a notification sound. The buzzer controller 31 causes the buzzer 32 to output a notification sound (beep sound) with a predetermined volume in response to an instruction sound output from the keyboard controller 30. The key switch 33 is a rotary switch that rotates only when a dedicated key is inserted, and outputs a mode signal for switching the operation mode in accordance with the rotation stop position. The operation modes that can be switched by the key switch 33 include a sales operation mode for executing a product sales operation, a setting mode for executing various settings, and the like.

  The keyboard 3 and the touch panel 21 function as operation input means in the present embodiment, and the speaker 22 and the buzzer 32 function as notification sound output means in the present embodiment.

[Volume setting processing]
Next, a volume setting process for setting the volume of the notification sound output from the speaker 22 and the buzzer 32 will be described.
In this process, the volume setting table 130 stored in the memory 13 is used. An example of the data structure of the volume setting table 130 is shown in FIG. The volume setting table 130 is configured by associating a volume with a time zone. In the illustrated example, volume A is associated with time zone A, volume B is associated with time zone B, volume C is associated with time zone C, and other time zones that do not belong to any of time zones A to C. Is associated with volume D. The time zone A indicates the normal time when there are many or fewer customers in the store, and the volume A indicates the medium volume. The time zone B indicates a crowded time with many customers in the store, and the volume B indicates a high volume. The time zone C indicates a quiet time when there are few customers in the store, and the volume C indicates a low volume. Further, the other time zone indicates, for example, the closing time, and the volume D indicates the minimum volume that is smaller than the low volume.

  While the merchandise sales data processing apparatus 1 is operating, the CPU 10 executes the operation program for volume setting processing stored in the memory 13 in parallel with other processing. FIG. 3 shows a flowchart of the volume setting process executed when the contents shown in FIG. 2 are registered in the volume setting table 130.

  At the beginning of the process, the CPU 10 first activates the timer 20 to start time counting (step S101). Next, the CPU 10 determines whether or not the time count of the timer 20 has reached the predetermined time T (step S102). This process is continued until the time count of the timer 20 reaches the predetermined time T. Note that the processing in step S102 is for reducing the processing load on the CPU 10 associated with the subsequent processing, and the predetermined time T is set to a time sufficiently smaller than each time zone A to C in the volume setting table 130. Has been.

  Eventually, when the time count of the timer 20 exceeds the predetermined time T (Yes in step S102), the CPU 10 stops the timer 20 and resets the time count (step S103), and reads the current time from the system clock 19 (step S103). S104). The read current time is temporarily stored in the memory 13.

Next, the CPU 10 extracts the volume associated with the time zone to which the current time temporarily stored in the memory 13 belongs from the volume setting table 130, and sets the volume of the notification sound output from the speaker 22 and the buzzer 32 to the extracted volume. Set (volume setting means).
That is, the CPU 10 determines whether or not the current time temporarily stored in the memory 13 belongs to the time zone A (step S105). If so (Yes in step S105), the CPU 10 determines the volume of the audio controller 17 and the buzzer controller 31. A is set (step S106). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of the volume A, and the buzzer controller 31 causes the buzzer 32 to output the notification sound of the volume A.

  On the other hand, when the current time temporarily stored in the memory 13 does not belong to the time zone A (No in step S105), the CPU 10 determines whether or not the same time belongs to the time zone B (step S107). If it belongs to the time zone B (Yes in step S107), the CPU 10 sets the volume B for the audio controller 17 and the buzzer controller 31 (step S108). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of volume B, and the buzzer controller 31 causes the buzzer 32 to output a notification sound of volume B.

  On the other hand, when the current time temporarily stored in the memory 13 does not belong to the time zone B (No in step S107), the CPU 10 determines whether or not the same time belongs to the time zone C (step S109). If belonging to the time zone C (Yes in step S109), the CPU 10 sets the volume C for the audio controller 17 and the buzzer controller 31 (step S110). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of the volume C, and the buzzer controller 31 causes the buzzer 32 to output the notification sound of the volume C.

  On the other hand, when the current time temporarily stored in the memory 13 does not belong to the time zone C (No in step S109), the CPU 10 sets the volume D for the audio controller 17 and the buzzer controller 31 (step S111). After this setting, the audio controller 17 causes the speaker 22 to output a sound notification of volume D, and the buzzer controller 31 causes the buzzer 32 to output sound notification of the volume D.

  The processes in steps S101 to S111 are repeatedly executed until the system of the merchandise sales data processing apparatus 1 is shut down.

[Table content change processing]
Next, a table content change process for changing the content of the volume setting table 130 will be described.

  When the operator rotates the key switch 33 and sets the stop position to the setting mode, a screen for the setting mode is displayed on the display 15. When the content change of the volume setting table 130 is designated by the touch operation of the GUI component displayed on this screen or the operation of the keyboard 3, the CPU 10 executes the operation program for the table content change process stored in the memory 13. . A flowchart of this process is shown in FIG.

  At the beginning of the process, first, the CPU 10 causes the display 15 to display a volume setting screen in which the contents of the volume setting table 130, that is, the time zone and the volume can be rewritten (step S201). Then, while accepting rewriting of the time zone and the volume shown on the screen (step S202), the completion of the rewriting is awaited (No in step S203). At this time, the operator can rewrite the time zone and the volume displayed on the screen by operating the keyboard 3 or touching the screen via the touch panel 21.

  Eventually, when the operator declares completion of rewriting by operating the keyboard 3 or touching the screen via the touch panel 21 (Yes in step S203), the CPU 10 updates the volume setting table 130 with the contents after the rewriting (step S203). S204), the table content changing process is terminated. After the content of the volume setting table 130 is changed in this way, the volume setting process is performed based on the changed content.

  As described above, the merchandise sales data processing apparatus 1 in this embodiment selectively sets the volume of the notification sound output from the speaker 22 and the buzzer 32 according to time. With such a configuration, it is possible to automatically set the sound volume of the optimum notification sound according to the time zone, so that it is not necessary for the operator to change the sound volume setting.

  The volume is set according to the volume setting table 130 whose contents can be changed in the setting mode. With such a configuration, it is possible to realize an optimum volume setting that appropriately reflects a change trend at the time of congestion or quiet time.

(Second Embodiment)
Next, a second embodiment will be described.
This embodiment is different from the first embodiment in that the volume of the notification sound is set according to the operator who is registered as the person in charge of the merchandise sales data processing apparatus 1.

[Responsible person registration process]
The person-in-charge registration process for registering the person in charge of operation of the merchandise sales data processing apparatus 1 will be described.
The merchandise sales data processing apparatus 1 is configured so that the merchandise registration work or the like cannot be executed unless the person in charge of the operation is registered through the processing. The person-in-charge table 131 stored in the memory 13 is used for the person-in-charge registration process. An example of the data structure of the responsible person table 131 is shown in FIG. The person-in-charge table 131 is configured by associating the names of shop assistants with the person-in-charge codes (identification information) that are not duplicated and assigned to the shop staff of the store. In the illustrated example, the name “operator A” is associated with the responsible person code “0001”, the name “operator B” is associated with the responsible person code “0002”, and the name “operator C” is associated with the responsible person code “0003”. The name “operator D” is associated with the responsible person code “0004”, and the name “operator E” is associated with the responsible person code “0005”.

  When a responsible person key provided on the keyboard 3 is pressed, the CPU 10 executes an operation program for responsible person registration processing stored in the memory 13. A flowchart of this process is shown in FIG.

At the beginning of the process, first, the CPU 10 displays a responsible person registration screen in which a responsible person code input field is provided on the display 15 (step S301). Then, while accepting the input of the person-in-charge code in the input field of the screen (step S302), it waits for the completion of the input (No in step S303). At this time, the store clerk can input the responsible person code by operating the keyboard 3, touching the screen via the touch panel 21, or reading the barcode indicating the responsible person code with the barcode scanner.
That is, the keyboard 3, the touch panel 21, and the barcode scanner constitute identification information input means in this embodiment.

  Eventually, when the clerk finishes inputting the responsible person code by the above method (Yes in step S303), the CPU 10 reads the clerk name corresponding to the inputted responsible person code from the responsible person table 131 and stores it in the memory 13. By storing the person-in-charge code and the store clerk name in the memory area for person-in-charge registration provided, the operator indicated by the person-in-charge code is registered as the person in charge of operation (step S304). The responsible person registration process is thus completed.

  When the person in charge of the operation is registered in this way, execution of a product registration work or the like is permitted. Furthermore, the name of the person in charge of the operation being registered is printed on a receipt issued in the merchandise registration business and recorded in the electronic journal.

[Volume setting processing]
Next, the volume setting process will be described.
An example of the data structure of the volume setting table 132 in this embodiment is shown in FIG. The volume setting table 132 is configured by associating the volume with the responsible person code. In the illustrated example, the volume A is associated with the responsible person code “0001” indicating the operator A in the responsible person table 131, the volume B is associated with the responsible person code “0002” indicating the operator B, and the responsible person indicating the operator C. The volume “C” is associated with the code “0003”, and the volume D is associated with all the other responsible person codes.
Note that the contents of the volume setting table 132 can be changed by a table content changing process similar to that of the first embodiment.

  FIG. 8 shows a flowchart of a volume setting process executed when the contents shown in FIG. 7 are registered in the volume setting table 132 in the present embodiment. At the beginning of the process, first, the CPU 10 determines whether or not the person in charge of operation is registered through the person-in-charge registration process (step S401). This process is repeatedly executed until the person in charge of the operation is registered (No in step S401).

When the person in charge of operation is registered (Yes in step S401), the CPU 10 extracts the volume associated with the person-in-charge code of the registered person in charge of operation from the volume setting table 132, and from the speaker 22 and the buzzer 32. The volume of the notification sound to be output is set to the extracted volume (volume setting means).
That is, the CPU 10 determines whether or not the person-in-charge code stored in the operation person-in-charge registration memory area matches the person-in-charge code “0001” of the operator A (step S402). In step S402, the volume A is set for the audio controller 17 and the buzzer controller 31 (step S403). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of the volume A, and the buzzer controller 31 causes the buzzer 32 to output the notification sound of the volume A.

  On the other hand, when the person-in-charge code stored in the operation person-in-charge registration memory area does not match “0001” (No in step S402), the CPU 10 determines that the person-in-charge code is the person-in-charge code “0002” of the operator B. (Step S404). If it matches the person-in-charge code “0002” (Yes in step S404), the CPU 10 sets the volume B for the audio controller 17 and the buzzer controller 31 (step S405). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of volume B, and the buzzer controller 31 causes the buzzer 32 to output a notification sound of volume B.

  On the other hand, when the person-in-charge code stored in the operation person-in-charge registration memory area does not match “0002” (No in step S404), the CPU 10 determines that the person-in-charge code is the person-in-charge code “0003” of the operator C. Is determined (step S406). If it matches the responsible person code “0003” (Yes in step S406), the CPU 10 sets the volume C for the audio controller 17 and the buzzer controller 31 (step S407). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of the volume C, and the buzzer controller 31 causes the buzzer 32 to output the notification sound of the volume C.

  On the other hand, when the person-in-charge code stored in the operation person-in-charge registration memory area does not match “0003” (No in step S406), the CPU 10 sets the volume D for the audio controller 17 and the buzzer controller 31. (Step S408). After this setting, the audio controller 17 causes the speaker 22 to output a sound notification of volume D, and the buzzer controller 31 causes the buzzer 32 to output sound notification of the volume D.

  After setting any of the sound volumes A to D to the audio controller 17 and the buzzer controller 31 in this way, the CPU 10 waits for the registration of the person in charge of operation currently registered (step S409). The person in charge of registration cancels the registration by executing the person-in-charge registration process again to register a new person in charge of operation or by depressing the registration release button provided on the keyboard 3. it can. When the registration of the person in charge of operation is canceled (Yes in step S409), the CPU 10 executes the processes in steps S401 to S409 again.

  As described above, the merchandise sales data processing apparatus 1 in this embodiment selectively sets the volume of the notification sound output from the speaker 22 and the buzzer 32 according to the operator registered as the person in charge of operation. With such a configuration, it is possible to automatically set the sound volume of the optimum notification sound according to the preference of the operator, so that it is not necessary for the post-change operator to change the sound volume setting every time the operator is changed.

  The volume setting is executed according to a volume setting table 132 whose contents can be changed in the setting mode. With such a configuration, when a store clerk code is assigned to a new store clerk, the setting desired by the store clerk is added to the volume setting table 132, and an optimal volume setting that appropriately reflects the store operating status is realized. it can.

(Third embodiment)
Next, a third embodiment will be described.
This embodiment is different from the first and second embodiments in that the volume of the notification sound output from the speaker 22 and the buzzer 32 is set according to the ambient noise of the merchandise sales data processing apparatus 1.

[Volume setting processing]
An example of the data structure of the volume setting table 133 in this embodiment is shown in FIG. The volume setting table 133 is configured by associating the volume with the noise range indicated by the sound pressure level. In the illustrated example, the volume A is associated with the noise range of the sound pressure levels A1 to A2 (A1 <A2), and the volume B is associated with the noise range of the sound pressure levels B1 to B2 (A2 ≦ B1 <B2). Volume C is associated with a noise range of pressure levels C1 to C2 (C1 <C2 ≦ A1), and volume D is set to other noise ranges that do not belong to any of sound pressure levels A1 to A2, B1 to B2, and C1 to C2. Associated. The noise range of the sound pressure levels A1 to A2 indicates a normal noise range in which many customers are entering the store, and the noise range of the sound pressure levels B1 to B2 is a noise range in crowded cases where there are many customers in the store. The noise range of the sound pressure levels C1 to C2 indicates a quiet noise range where there are few customers in the store, and the other noise ranges indicate the noise range when there are no customers in the store, such as when the store is closed.
Note that the content of the volume setting table 133 can be changed by the same table content changing process as in the first embodiment.

  FIG. 10 shows a flowchart of the volume setting process executed when the contents shown in FIG. 9 are registered in the volume setting table 133 in the present embodiment.

  At the beginning of processing, the CPU 10 first activates the timer 20 to start time counting (step S501). Next, the CPU 10 determines whether or not the time count of the timer 20 has reached the predetermined time T (step S502). This process is continued until the time count of the timer 20 reaches the predetermined time T. Note that the processing in step S502 is for reducing the processing burden on the CPU 10 associated with the execution of the subsequent processing, and the predetermined time T is the volume of the notification sound that accurately reflects the change in the store noise in the subsequent processing. Is set to a sufficiently small time so that can be set.

  Eventually, when the time count of the timer 20 exceeds the predetermined time T (Yes in step S502), the CPU 10 stops the timer 20 and resets the time count (step S503). Thereafter, the CPU 10 instructs the audio controller 17 to measure the sound pressure level of noise (step S504). At this time, the audio controller 17 takes in a signal that the microphone 23 collects and outputs from the surroundings, measures the sound pressure level based on the taken-in signal, and notifies the CPU 10 of it. When the sound pressure level measured in this way is notified, the CPU 10 temporarily stores the notified sound pressure level in the memory 13.

Next, the CPU 10 extracts the volume associated with the noise range to which the sound pressure level temporarily stored in the memory belongs from the volume setting table 133, and sets the volume of the notification sound output from the speaker 22 and the buzzer 32 to the extracted volume. Set (volume setting means).
That is, the CPU 10 determines whether or not the sound pressure level temporarily stored in the memory 13 belongs to the noise range of the sound pressure levels A1 to A2 (step S505), and if so (Yes in step S505), the audio controller 17 The volume A is set for the buzzer controller 31 (step S506). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of the volume A, and the buzzer controller 31 causes the buzzer 32 to output the notification sound of the volume A.

  On the other hand, when the sound pressure level temporarily stored in the memory 13 does not belong to the noise range of the sound pressure levels A1 to A2 (No in step S505), the CPU 10 determines whether or not the sound pressure level belongs to the sound pressure levels B1 to B2. Is determined (step S507). If it belongs to the noise range of the sound pressure levels B1 and B2 (Yes in step S507), the CPU 10 sets the volume B for the audio controller 17 and the buzzer controller 31 (step S508). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of volume B, and the buzzer controller 31 causes the buzzer 32 to output a notification sound of volume B.

  On the other hand, when the sound pressure level temporarily stored in the memory 13 does not belong to the noise range of the sound pressure levels B1 to B2 (No in step S507), the CPU 10 belongs to the noise range of the sound pressure levels C1 to C2. It is determined whether or not (step S509). If it belongs to the noise range of the sound pressure levels C1 to C2 (Yes in step S509), the CPU 10 sets the volume C for the audio controller 17 and the buzzer controller 31 (step S510). After this setting, the audio controller 17 causes the speaker 22 to output a notification sound of the volume C, and the buzzer controller 31 causes the buzzer 32 to output the notification sound of the volume C.

  On the other hand, when the sound pressure level temporarily stored in the memory 13 does not belong to the noise range of the sound pressure levels C1 to C2 (No in step S509), the CPU 10 sets the volume D for the audio controller 17 and the buzzer controller 31 ( Step S511). After this setting, the audio controller 17 causes the speaker 22 to output a sound notification of volume D, and the buzzer controller 31 causes the buzzer 32 to output sound notification of the volume D.

  The processes in steps S501 to S511 are repeatedly executed until the system of the merchandise sales data processing apparatus 1 is shut down.

  As described above, the merchandise sales data processing apparatus 1 according to the present embodiment selectively sets the volume of the notification sound output from the speaker 22 and the buzzer 32 according to the ambient noise. With such a configuration, it is possible to automatically set the sound volume of the optimum notification sound according to the ambient noise, so that it is not necessary for the operator to change the sound volume setting on the basis of the level of the ambient noise.

  The volume setting is executed according to a volume setting table 133 whose contents can be changed in the setting mode. With such a configuration, it is possible to realize an optimum volume setting that appropriately reflects the change trend and the noise level during congestion and quiet times.

(Modification)
Note that the configuration disclosed in each of the embodiments can be embodied by appropriately modifying each component in the implementation stage. Specific examples of modifications are as follows.

(1) In each of the above-described embodiments, the case where four volume levels A to D are registered in the volume setting table is illustrated. However, a larger or smaller volume may be set in the volume setting table. Alternatively, without using the volume setting table, the volume may be calculated using a time zone, ambient noise, and the like and a predetermined calculation formula, and the calculated volume may be set as the volume of the notification sound.

(2) In each of the above embodiments, the case where the volume setting table is stored in the memory 13 is exemplified. However, a higher level device such as a store server may be provided with a volume setting table so that processing equivalent to a part of the volume setting process is executed by this higher level device.
