Next, the control for causing these display screens to appear on the screen of the cashier display 28 will be described with reference to flowcharts shown in FIGS. In these flowcharts,
“F” indicates a registering flag, F = 1 during product registration, and F = 0 by a closing operation by pressing the deposit / current total key 35. “Fd” indicates a flag during image display, and Fd = 1 when the image of the monitoring camera 1 is displayed and Fd = 0 when the image of the monitoring camera 1 is not displayed.
“N” is a counter value indicating the number of the surveillance camera 1a to 1e displaying an image, and n = 1 is the surveillance camera 1a, n = 2
Corresponds to the monitoring camera 1b, n = 3 corresponds to the monitoring camera 1c, n = 4 corresponds to the monitoring camera 1d, n = 5 corresponds to the monitoring camera 1e, and n
= 0 corresponds to the four-split display of the monitoring cameras 1a to 1d.
The counter value n is set so as to return to 0 when it reaches 6.

First, it is checked whether or not the registration mode has been set by the mode switch 20 (step S).
1). In this check, if it is determined that the mode is the registration mode, it is checked whether or not barcode information of a product is input by the barcode scanner 24 (S).
2). When barcode information is entered, registration is in progress,
The registering flag F is set to 1 (S3), and based on the product code in the bar code information, the product name and unit price of the corresponding product code are called from the PLU memory or the like, the number of product files is incremented by +1 and the unit price is totaled. The product registration process for the product is performed by adding it to the price (S4). Then, product information on the registered product is displayed on the cashier display 28,
If Fd = 0 during the image display and the image mode is not set by the image / erase key 36 (N in S5), the image is displayed in the form of the display screen A as shown in FIG. 6 (S6).
On the other hand, if the image mode is set by the image / erase key 36 and Fd = 1 during image display (Y in S5), FIG.
Display in the form of a display screen B as shown in FIG.
7). The merchandise registration processing involving the display on the display screen A or B is repeated in the same manner until a closing declaration is made by operating the deposit / current total key 35.

Therefore, even during the merchandise registration processing, if the video mode is designated by the video / erase key 36,
The video from the surveillance camera 1 is also displayed as the surveillance camera small screen 41 on the screen of the cashier display 28 that displays the product registration information. You can check. At this time, the display mode is a display mode such as the display screen B, and even if the surveillance camera small screen 41 appears, the details of the product registration information are displayed on the screen without missing, so the original product sales registration process is performed. The accompanying display function is not impaired.

By the way, when the video / erase key 36 is pressed at any time during the merchandise registration process (Y in S20), depending on whether Fd during video display is 1 or not (S21). , Different processing is performed. First, unless Fd = 1 during image display, the erase mode has been set, so Fd is set to 1 during image display to set the image mode (S22). In this case, since F = 1 during registration (Y in S23), the image of the n-th monitoring camera 1 indicated by the counter is displayed in the form of the display screen B (S2).
4). That is, the display screen A is switched to the display screen B in accordance with the operation of the video / erase key 36. On the other hand, if the video mode is already set and Fd = 1 during video display (Y in S21), Fd = 0 during video display and the erase mode is set (S26). And the indicator 2 for the cashier
The surveillance camera small screen 41 is deleted from the screen 8 and displayed in the form of the display screen A (S27). That is, the display screen B is switched to the display screen A in accordance with the operation of the video / erase key 36.

On the other hand, when the image selection key 37 is depressed at any time during such product registration processing (S
28, Y), if Fd = 1 during video display (Y in S29), depending on whether or not F being registered is 1 (S30),
Different processing is performed. In this case, since the merchandise registration processing is being performed and the registration is being performed, F = 1 (Y in S30), the counter value is increased by +1 by pressing the video selection key 37.
The image is incremented (S31), and the image of the surveillance camera 1 of the next number becomes the display screen B displayed on the surveillance camera small screen 41 (S32). Then, use the numeric keypad 32
When any one of the keys 5 is pressed (Y in S33), the set numerical value is set to the counter value n (S34), and the image of the surveillance camera 1 of that number is displayed on the surveillance camera small screen 41. The display screen B is displayed (S35). If the numeric keypad 32 is not operated, the display state in step S32 is maintained. When the image selection key 37 is repeatedly pressed, images of the monitoring cameras 1a to 1e are displayed one after another. In this way, by appropriately operating the video selection key 37 and the numeric keypad 32, the surveillance camera small screen 41 on the display screen B is displayed.
The images of the surveillance cameras displayed on the surveillance cameras 1a to 1e
You can switch to any of them.

Thereafter, when the merchandise registration processing is completed and the deposit / current total key 35 is operated to declare the closing (Y in S8),
During registration, F is switched to 0 (S9). Then, a total amount including the tax amount and the like is calculated and displayed on the display unit 26, and a change amount is calculated from the deposit amount and the total amount upon receiving payment from the customer, and a closing process for displaying the change amount on the display unit 26 is performed. At the same time as (S10), as a continuation of the closing process, the drawer 15 is opened to enable the transfer of money (S11).
During such a series of closing processing, it is checked whether or not Fd during image display is 1 (S12), and Fd = 1 during image display.
Otherwise, the closing process information is displayed on the screen of the cashier display 28 in the display form of the display screen A (S13). Thereafter, it is checked whether there is a change in key input, bar code scanner input or mode (S14). If there is no change, a timer counter determines whether a certain time has elapsed since the operation of the deposit / current total key 35. (S15). Then, after a certain time has elapsed, the display screen is switched to the display screen C including the surveillance camera large screen 42 (S1).
6).

On the other hand, in the check of Fd during image display in step S12, if Fd = 1, it is checked whether there is a change in key input, barcode scanner input or mode (S17). , Deposit / current total key 35
It is determined based on the count value of the timer counter whether a predetermined time has elapsed since the operation of (S18). Then, when a certain time has elapsed, the screen of the cashier display 28 is switched from the display screen B including the surveillance camera small screen 41 to the display screen C for tightening processing including the surveillance camera large screen 42 (S19). That is, as illustrated in FIG.
An image of the surveillance camera 1 with the counter value n is displayed on the surveillance camera large screen 42, and the closing processing information 43 including the total amount, the deposit amount, and the change amount in one transaction is displayed outside the margin. Become. This step S1
The process shown in FIG. 9 is a switching process from the monitoring camera small screen 41 to the monitoring camera large screen 42 based on the closing timing of step S8, and is executed by the monitoring camera screen size switching unit. After the deposit / current total key 35 is pressed,
It is determined whether or not a predetermined time has elapsed (S8 and S1).
8), which is executed by the switching timing certifying means, and the certifying point that a certain time has passed is the closing timing = switching timing.

According to this, even if the deposit / current total key 35 is depressed, the transaction details are displayed in a display form such as the display screen B shown in FIG. Since it remains on the screen of the cashier display 28, it is possible to easily confirm and determine, for example, whether or not a discount processing has been performed on the screen during the closing processing. That is, the original function as the cashier display 28 is secured for a certain period of time. If the display of the cashier display 28 is immediately switched from the display screen B to the display screen C when the deposit / current total key 35 is pressed and the transaction details are deleted, the customer is distrusted with the registration work. There is a concern that the user may feel uneasy or uneasy, but by switching after a certain period of time, such a fear is resolved. On the other hand, when the screen is switched to the display screen C, the image of the surveillance camera 1 is easily viewed on the cashier display 28. Even if change processing or the like remains at this point, the closing processing information 43 is displayed on the display screen C, so that there is no hindrance to the closing processing of the original product sales registration processing.

If the image / erase key 36 is depressed at any time even after the deposit / current key 35 is depressed (Y in S20), it is determined whether or not Fd is 1 during image display. (S21), different processing is performed. First, unless Fd = 1 during image display, the erase mode has been set, so Fd is set to 1 during image display to set the image mode (S22). And in this case during registration F = 0
(N in S23), the image of the n-th monitoring camera 1 indicated by the counter is displayed in the form of the display screen C (S23).
25). That is, the display screen A is switched to the display screen C in accordance with the operation of the video / erase key 36. On the other hand, if the video mode is already set and Fd = 1 during video display (Y in S21), Fd = 0 during video display and the erase mode is set (S26). Then, the surveillance camera large screen 42 is deleted from the screen of the cashier display 28 and displayed in the form of the display screen A (S27). That is, the display screen C is switched to the display screen A in accordance with the operation of the video / erase key 36.

On the other hand, after the operation of the deposit / current total key 35, when the image selection key 37 is pressed at any time (Y in S28), if Fd = 1 during image display (S2).
9 (Y), according to whether or not F is 1 during registration (S3
0), different processing is performed. In this case, since the closing declaration has been made and F = 0 during registration (N in S30),
Pressing the image selection key 37 increases the counter value by +
The image is incremented by one (S36), and the image of the surveillance camera 1 of the next number becomes the display screen C displayed on the surveillance camera large screen 42 (S37). Continue using the numeric keypad 32
When any one of the keys (5) to (5) is pressed (Y in S38), the set numerical value is set to the counter value n (S39), and the image of the surveillance camera 1 of that number is displayed on the surveillance camera large screen 42. The display screen C is displayed (S40). If the numeric keypad 32 is not operated, the display state in step S37 is maintained. When the image selection key 37 is repeatedly pressed, images of the monitoring cameras 1a to 1e are displayed one after another. In this way, by appropriately operating the video selection key 37 and the numeric keypad 32, the surveillance camera large screen 4 on the display screen C is displayed.

It can be switched to any of e.

When the mode is set to the video mode by the mode switch 20 (S41), the display 28 for the cashier is used for monitoring, and the counter is displayed in the form shown on the display screen D as shown in FIG. The image of the surveillance camera 1 indicated by the value n is displayed on the entire surface of the cashier display 28 (S42). When the counter n = 0, the display screen E is as shown in FIG. 7B. In any case, since this video mode has nothing to do with the merchandise sales registration process, there is no problem even if only the camera video is displayed.

In this image mode, when the image selection key 37 is pressed at any time (Y in S43), the counter value is incremented by +1 (S44), and the image of the surveillance camera 1 of the next number is displayed on the display screen D. Or the images of the surveillance cameras 1a to 1d are displayed on the display screen E (S45). Subsequently, when any one of the keys 0 to 5 is pressed with the ten keys 32 (Y in S46), the numerical value set is set to the counter value n (S47), and the image of the monitoring camera 1 of that number is displayed. It is displayed on the screen D, or the images of the monitoring cameras 1a to 1d are displayed on the display screen E (S
48).

When the image selection key 37 is not pressed (S
(N of 43) or when the numeric keypad 32 is not pressed (S46)
In N), the same display state is continued. Thereafter, the same video display is repeated until the video mode is released by the mode switch 20, and when the video mode is released (S49).
N), the image display on the cashier display 28 is erased (S50).

Therefore, the cashier display 28 can be effectively used as a monitor for a surveillance camera during an idle time when the merchandise sales registration work is not performed.

In the present embodiment, the display screen B
Is switched to the display screen C at the time when a predetermined time has elapsed after the deposit / current total key 35 is pressed. For example, when the drawer 15 is closed, the display screen B is switched to the display screen C. You may do so. FIG.
