Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article equipped with an AC power supply-driven cashier display for displaying cashier display data and a DC power supply-driven customer display for displaying customer display data. The present invention relates to a sales registration data processing device.

[0002]

2. Description of the Related Art For example, in an electronic cash register type product sales registration data processing device, in the registration mode, when a product code is entered by using a scanner, the CPU searches the product file and the product data (product name, unit price). Etc.) and register this as sales data in the sales file.
Product data is displayed on the cashier display and customer display along with the product code. Therefore, the cashier can confirm that the input is correct, and the customer can confirm the unit price.

When the cashier has registered all of the customer-purchased products, he carries out a closing operation to declare the end of one transaction. Then, the accounting process including the calculation of the total amount, the change amount, etc. is executed. This total amount is also displayed on both display devices together with the sales data (product data). Therefore, the customer can quickly settle the payment amount and the cashier can predict the payment amount.

After that, the drawer is automatically opened and a receipt is issued. One transaction ends. Various kinds of guidance for performing the above-mentioned product registration work are displayed on the cashier display.

In the setting mode, the cashier can set the constants in various programs and the product data in the product file. The cashier is based on the guidance displayed on the cashier display.

Further, if the inspection mode is set, the merchandise data registered so far can be confirmed in the form of an inspection report. If you use the payment mode, you can get a report with all the sales data (registration contents) of the day and clear the sales file. In each case, the guidance and input data displayed on the cashier display are checked. In addition to this, for example, when the business is suspended or stopped, the OS and application software (A
PL), RAM disk information, etc. or sales data,
It is also possible to save it in the HDD or the like.

As described above, both display devices play an important role in accurately and smoothly executing various works including product registration work. The customer display data is mainly product data in the product registration process, total amount of money in the accounting process, and service information, and therefore has a small absolute amount. Therefore, it is small in size and is generally of a DC power source drive type such as a liquid crystal display (LCD).

On the other hand, the display data for cashier contains the same contents as the display data for customers, and also contains various guidance and information necessary for performing the work in each mode, so that it becomes a large amount. Therefore, it is formed from a large size CRT, for example. All or part of such a large CRT is driven by using an AC power source.

By the way, in the electronic cash register,
Not only the drive power supply for the customer display, but also the drive power supply for various devices (printers, drawers, scanners, etc.)
A power supply unit and a battery having an AC-DC conversion function are provided for storing and storing various programs developed in AM, product data, sales data, and the like.

Therefore, if the battery is charged when the AC power supply is normally energized, even if the AC power supply is temporarily or briefly short-circuited, various programs developed in the RAM, product data, and sales data can be stored. Since it is possible to leave it, it is possible to continue various business operations as soon as the AC power supply is restored.

[0011]

However, even in a store or the like, the power supply capacity may become tight due to the introduction / expansion of various devices, and the voltage of the AC power supply may drop or a power outage may occur for a relatively long time.

Then, by switching to the battery, various data expanded in the RAM are saved. Further, if the product registration work is in progress, the customer display data can be displayed on the customer display. However, since the cashier display is an AC power source drive type, it cannot display the cashier display data at all.

Therefore, not only the product registration work (work) must be interrupted, but also the saving and saving work (work) of various data, which is indispensable when the power outage is prolonged, cannot be executed. That is, input data and product data during registration are lost, and the AC power supply must be restored and the process must be restarted from the beginning. In the worst case, the sales data up to now is lost before being saved in the HDD or the like, which causes an irreversible situation.

An object of the present invention is to provide an easy-to-handle product which can display cashier display data by switching it to a customer display when a power failure occurs in an AC power supply, thereby reliably performing work such as storing various data. To provide a sales registration data processing device.

[0015]

SUMMARY OF THE INVENTION The present invention comprises an AC power supply driven cashier display for displaying cashier display data and a DC power supply driven customer display for displaying customer display data. In the product sales registration data processing device described above, the display screen of the customer display is formed to be switchable from the customer side to the cashier side, and a power failure detecting means for detecting a power failure of the AC power source and a power failure are detected. On the condition that the display data for cashier is switched and displayed on the display screen of the display for customer, the display data switching display control means for cashier is provided.
It is characterized by the following.

[0016]

According to the present invention having the above construction, when the power failure detection means detects a power failure of the AC power source, the display data switching display control means switches the cashier display data to the display screen of the customer display and displays it. Therefore, if the cashier turns the display screen to his or her side, the predetermined cashier display data can be viewed from the display screen of the customer display unit, so that various operations such as storing various data can be surely performed. .

Therefore, even if the AC power supply fails and the cashier display data cannot be displayed on the cashier display device, subsequent troubles can be prevented and the work can be continued immediately if the AC power supply is restored. Can be executed.

When the battery voltage Vbt of the battery 28 becomes equal to or lower than the set voltage Vbt2 (YES in ST39 of FIG. 4), the power supply unit 29 outputs the charging signal Sbvl (H level) to charge the battery ( ST40,
41, 42). This charging signal Sbvl is received (S in FIG. 3).
The engine unit 21 that has performed YES in T13 displays that the battery is being charged on the cashier display 33 (ST).
14). When the charging ends at time t4, the charging signal Sbvl disappears (L level) (YES in ST42 of FIG. 4, ST43).

For example, at time t5 in FIG. 5, when the power switch SW is turned off or the AC power source AC loses power,
The AC power supply signal MPWR of the power supply unit 29 is set to the L level,
At the time t6 immediately after that, the AC normal signal Sac disappears (L level) (ST32, 33 in FIG. 4). Then, the engine unit 21 stops the work (S in FIG. 3).

Further, in the case of this embodiment, the AC power source A
In preparation for a power failure of C, a work program and a data save program are stored in the ROM 23 of the engine section 21 and formed so that whether or not to execute them can be set by key operation.

That is, if the work program has been set (YES in ST18 of FIG. 3), the work can be continued (NO in ST20 and ST21). Further, when the work program is not set and the data save program is set (NO in ST18 of FIG. 3, YE in ST22)
In S), the work is stopped, and various data expanded in the RAM 24 is automatically saved in the HDD 26 (ST23, ST24).

However, even if the work program is set (YES in ST18) and the work can be continued, there are cases where the cashier tries to achieve safety while considering the power capacity of the battery 28 and the like. Therefore, a data save request (YES in ST19) is performed by operating the keys on the keyboard 31.

In the display switching setting signal Soff, the battery voltage Vbt becomes the low voltage Vbt1 shown in FIG.
Time t7 when the DC power supply DC supplied to the engine unit 21 drops or time t7 when the power switch SW is turned off
, It is formed to be once cleared (H level). However, the keyboard 31 is not automatic like this.
A setting key may be provided on the upper side so that the cashier can be selectively set.

Next, the operation of this embodiment will be described. When the AC power supply AC and the DC power supply DC based on it are normal, the cashier display data is displayed on the cashier display 33 (ST11 in FIG. 3), and the customer display data is displayed on the customer display 32. ing. Therefore, various operations such as product registration processing and accounting processing can be performed as usual (ST12).

At time t5 in FIG. 5, when the AC power supply AC has a power failure, the power failure detecting means (29) detects the power failure. Then, at time t6, the AC normal signal Sac is changed from the H level to the L level (YES in ST31 of FIG. 4, ST33).

If the display switching setting signal Soff is set (L level) here (YE in ST16 of FIG. 3).
S), the display data switching display control means (22, 23) on the engine part 21 side displays the cashier display data by switching from the cashier display 33 to the customer display 32 (ST17). In this case, the customer display data is
Do not show.

At the same time, the power supply unit 29 turns on the battery 28 (YES in ST34 and N in ST35 in FIG. 4).
O, ST36) to secure the drive power source (DC) for the customer display 32.

Thus, when the work program is set on the engine section 21 side (YE in ST18 of FIG. 3).
S) is permitted to continue the work (ST20). Therefore, the cashier can continue the work by directing the display screen of the customer display unit 32 to his side. For example, it is possible to continue and complete the merchandise item registration process and accounting process for a certain customer.

When considering the power capacity of the battery 28 and the power outage time for safety, for example, the next customer's product registration is interrupted after explanation of the circumstances, and data is operated by operating the keys on the keyboard 31. Make a save request (ST
19 YES). Then, the work is stopped (ST23) and the customer display 32 displays the data save guidance as the cashier display data. The cashier saves data accordingly (ST2

On the other hand, no work program is set (ST
18 NO), data save program has been set (ST
If YES, the work is automatically stopped by the CPU 22 (ST23), and the data selected and set in advance is automatically saved based on the data save program (ST24).

The charging function for the power supply unit 29 (see FIG.
ST39 to 43) and so on are the same as in the case of the conventional example, and a description thereof will be omitted.

According to this embodiment, however, the display screen of the customer display 32 is formed so that the direction of the display can be switched from the customer side to the cashier side, and the power failure detecting means (2
9) and display data switching display control means (22, 23) are provided so that the display data for cashier can be switched from the display 33 for cashier to the display 32 for customer when the AC power supply AC fails. Since it is configured, even if the cashier display 33 cannot be displayed, the cashier display data can be viewed from the display screen of the customer display 32 whose orientation has been changed. Therefore, even if the AC power supply AC fails, it is possible to continue, for example, product registration work that was in the middle of work until then, and to reliably perform various data storage work and the like while the battery voltage is present.

Display data switching display control means (2
2 and 23), the switching display operation is performed when the display switching setting signal Soff is set (L level), and the display switching setting signal Soff is the power switch SW ON.
Since it is formed to be automatically set while clearing once by -OFF or monitoring of the battery voltage Vbt, it is possible to reliably continue the work and save the data by using the customer display 32 no matter what time the power failure occurs.

Further, in connection with the display switching control, the work program and the data save program can be selectively set, so that the proper operation can be performed according to, for example, the capacity of the battery 28, and the applicability can be further expanded.

Since the data save program can be selected and set, sales data and the like can be saved more reliably, and the battery 28 can have a small capacity and a small size.

By requesting a data save at any time during continuous operation, the data can be saved by looking at the guidance (display data for cashier) displayed on the customer display 32, which is convenient for the power outage and the customer. Can respond to the operation.
