Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a device section, a control section, a power supply section having an AC / DC converting function, and a battery, and is formed so that various operations can be performed using a battery power supply even when the AC power supply fails. Product sales registration data processing device.

[0002]

2. Description of the Related Art FIG. 8 shows an electronic cash register 10 type product sales registration data processing apparatus including a control section 20 and an equipment section 30.

The control unit 20 is composed of an engine unit 21 including a CPU, a ROM, etc., a power supply unit 29, an HDD (hard disk device) 26, and an FDD (floppy disk device) 27, and drives and controls the equipment unit 30 in a timely manner.

The device section 30 includes a keyboard 31, a scanner 32, a cashier display 33, and a customer display 3.
4, a printer 35 and a drawer 36, and is driven by a DC power supply DC output from a power supply unit 29 having an AC-DC converting function. The power supply unit 29 charges the battery 28 when the AC power supply AC is normal, and outputs the DC power supply DC from the battery power supply when a power failure occurs.

Such a product sales registration data processing device (1
In 0), in the case of the registration mode, the scanner 3 as an input means is used.
When the product code is input using the keyboard 2 to the keyboard 31, the engine unit 21 searches the product file for product data (product name, unit price, etc.) and registers this as sales data in the sales file. The product data is displayed together with the product code on the cashier display 33 and the customer display 34, which are output means. Therefore, the cashier can confirm that the input is correct, and the customer can confirm the unit price and the number thereof.

When the cashier has registered all the customer-purchased merchandise, the cashier performs 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 33 and 34 together with the sales data. Therefore, the customer can quickly prepare the payment amount and the cashier can predict and confirm the payment amount.

After that, the drawer 36 is automatically opened, and the receipt printed by the printer 35 is issued. 1
The transaction ends. The product registration process and the accounting process are performed with reference to various guidances displayed on the cashier display device 33.

In the setting mode, constants in various programs and product data in product files can be set.
The cashier is performed based on the guidance displayed on the cashier display device 33. Furthermore, if the inspection mode is set, the product data registered up to that point can be confirmed at any time in the form of an inspection report. The engine unit 21 drives and controls the printer 35 by key operations on the keyboard 31 and executes the printer 35. In the payment mode, it is possible to obtain a payment report in which all the sales data of the day has been entered, and it is possible to automatically clear the sales file. In addition to this, for example, at the time of business interruption or suspension, sales data or OS, APL and RAM disk information expanded in RAM, etc.
It is possible to perform the work of saving in the DD 26 and the like.

As described above, since various operations necessary for performing various important tasks are executed, the power supply unit 29 is backed up by the battery 28 as described above.
Even when the AC power supply AC fails, various operations can be continued.

[0010]

By the way, such a product sales registration data processing device (10) is no exception, and it is strongly demanded that the size, weight, and cost be further reduced. Tend to However, the selection work in the event of a power outage is arbitrary, and the equipment used and its combination differ depending on the selection work,
Each device (21, 31, 33, 32, 34, 35, 35,
The power consumption of 36) is different.

Further, a card reader / writer, a stationary scanner, an automatic change dispenser, etc. are often added, and the types of constituent devices tend to be expanded.

[0012] Thus, depending on the selected work, there is a tendency that the necessary operation cannot be completed. For example, if the product registration is not completed during the product registration process, the accounting process cannot be executed for the customer, which not only lowers the customer service but also may damage the credibility of the store. Further, if the battery power is lost before the RAM disk is completely saved and stored in the HDD 26, various data before the power failure will be lost before the restart, so that the data must be reset. Moreover, if there is data that cannot be reset (for example, a part of sales data), irreversible damage will occur.

On the other hand, in order to avoid resetting various data, product registration is often stopped relatively early after a power failure, and the product is saved and stored. In such a case, the battery power source is sufficiently secured. In other words, as a result, it can be said that the capacity of the battery has become excessive.

An object of the present invention is to perform a commodity sales registration data process capable of completing a job selected to be executed after a power failure and accurately selecting a job that can be completed before the battery power is lost. To provide a device.

[0015]

The present invention comprises an equipment section, a control section, a power supply section having an AC / DC conversion function, and a battery, and is capable of executing various operations using a battery power supply even when the AC power supply fails. In the formed merchandise sales registration data processing device, a device-specific current consumption data table capable of storing current consumption data of each component device, and the component devices stored in the device current consumption data table Total consumption for reading the consumption current data stored in the consumption current data table for each selected configuration device and the addition device selection means for selecting the configuration device to be used to obtain the total consumption value Current value calculation means, operable time calculation means for calculating operable time using the calculated total current consumption value and the capacity of the battery, It is characterized in that a remaining time calculating means for obtaining an operable remaining time by subtracting an elapsed time from the issued operable time and a display control means for displaying the calculated remaining time on a display are provided. .

[0016]

In the case of the present invention having the above-mentioned configuration, the equipment to be used is selected by using the equipment selection means to be used after the power failure. Then, the total current consumption value calculation means reads and adds each current consumption data stored in the device-specific current consumption data table for each selected device, and the total current consumption required to execute the selected task. Calculate the value.

Subsequently, the operable calculation means calculates the operable time using the calculated total current consumption value and the battery capacity. Further, the remaining time calculating means subtracts the elapsed time from the time of switching to the battery power source from the operable time calculated in this way to obtain the operable remaining time. This remaining time is displayed on the display by the display control means.

Therefore, for example, due to the remaining time, it is possible to prevent the product registration process for the next customer from entering the product registration process for the next customer after the accounting process for the current customer is completed. It is possible to avoid in advance a situation in which business is suspended during registration processing and accounting processing. In addition, whichever task is being executed, depending on the remaining time, it is possible to switch and select the highest priority, for example, the saving storage of the RAM disk.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the product sales registration data processing device is basically composed of an electronic cash register 10 similar to that of the conventional example (FIG. 8), and has a device-specific current consumption data table 24T and a device used. Selection means (31)
, Total current consumption value calculation means (22, 23), operable time calculation means (22, 23), and remaining time calculation means (2
2, 23) and display control means (22, 23) are provided,

The usage flag (“1”) is stored (set) in the usage column of the selected device storage table (flag memory of FIG. 3) integrated with 4M (ST12). If not used, unused key K
When 2 is turned on (YES in ST13), the unused flag (“0”) is set in the unused column (ST16). In the end key K3, the end flag (“1”) is set in the end column (YES in ST15, ST1).
6). In the case of FIG. 3, a case is shown in which component devices required to execute the merchandise item registration process and the accounting process are selected.

The total current consumption value calculating means is a means for reading and adding the respective current consumptions of the selected constituent devices (names), and the ROM 23 and CP which store the addition program.
It is formed from U22 and is executed in ST18 of FIG.
The total current consumption value in the selected state shown in FIG.
The data memory 2 shown in FIG.
It is stored in the left column of 4M (ST19).

The operable time calculating means uses the total current consumption value (mA) thus calculated and the preset battery capacity (mAH) to calculate the operable time (in this embodiment, "min"). )), A ROM 23 storing the calculation program and a CPU 22, and is executed in ST20 of FIG. The calculated operable time is stored in the data memory 24 by the CPU 22.
It is stored in the right column of M (ST21).

The remaining time calculating means is composed of the ROM 23 storing the calculation program and the CPU 22, and subtracts the elapsed time from the calculated operable time to calculate the remaining time in which all of the selected components can be operated. (ST3 in FIG. 7
4) Do.

This elapsed time corresponds to the counter 21 shown in FIG.
Counted by NCT. That is, at time t1 when the signal PWGOOD shown in FIG. 5 becomes “L”, the counter 21CNT is set (ST31 in FIG. 7) and counting is started.

Therefore, the remaining time calculating means (22, 2)
In 3), both the signal BATLOW and the signal BATOFF are at the L level (YES in ST32, ST33).
In YES), the remaining time is calculated (ST34). The counter 21CNT is cleared (ST37) after the remaining time becomes zero (0).

The display control means is composed of the ROM 23 storing the display control program and the CPU 22, and the remaining time calculated (ST34) is displayed on the cashier display 3.
3 is displayed (ST36). It should be noted that the customer display 34 may also be displayed.

In the case of the embodiment having such a construction, the operator uses the equipment selection means (31) for the construction equipment necessary for executing the business operation to be continued while the AC power supply AC is stopped in advance or at the time of power failure. To select.

For example, when attempting to complete the accounting work for a customer who is in the product registration work, the device name necessary for executing the product registration process and the accounting process is selected. That is, when the command is issued, the device name display control means (22, 23) first operates, and the device name displayed in the device-specific current consumption data table 24T (including the flag memory) shown in FIG. Indicator for cashier 3
A list is displayed in 3 (ST10 in FIG. 6).

Thus, while visually confirming this display, the operator selects the engine section, the keyboard, the scanner, the cashier display, the customer display, the printer and the drawer in order using the use key K1. That is, the use flag (“1”) is set (YES in ST11,
ST12). For the HDD and the like, the unused flag (“0”) is set using the unused key K2 (YES in ST13, ST14). Then, when the selection end declaration (YES in ST15) is made using the end key K3, the end flag ("1") is set (ST16).

Then, the total current consumption value calculating means (22, 2)
3) shows the consumption currents (500, 10,
(20,400,150,1000,20mA) is read and summed up to calculate the total current consumption value (2080mA) (S
T18). The CPU 22 stores this (ST19) in the left column of the data memory 24M shown in FIG. Continued,
The operating time calculating means (22, 23) uses the calculated total current consumption value (2080 mA) and the preset battery capacity (1400 AH) to store the operable time (3
6 min) is calculated (ST20) and stored (ST2)
1) Yes.

Becomes L level (YES in ST30 of FIG. 7), CP
U22 displays a power failure on the cashier display 33. The DC power source DC is switched to the battery power source.

Here, the counter 21CNT is set (ST31), the elapsed time is counted, and the remaining time calculating means (22, 23) subtracts the elapsed time (min) from the operating time (36 mon) shown in FIG. Then, the remaining time is calculated (ST34). Display control means (22,
23) displays the remaining time on the cashier display 33 (ST36).

Since the operator can confirm the remaining time (for example, 30 minutes) from this display, the customer A
The product registration can be continued and the accounting process can be completed as usual. Furthermore, the customer B, who is lined up,
It is possible to accurately estimate that C, D, and E can be registered and accounted for. For the next customer F and after,
