Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a commodity sales registration data processing device such as an electronic cash register and a POS (point of sale information management) terminal.

[0002]

2. Description of the Related Art Generally, electronic cash registers and P
A product sales registration data processing device such as an OS terminal forms a total area in a built-in RAM (random access memory), and sells products such as the sales points and sales prices of each product registered by the product registration means. Registration work for accumulating and storing the data in the totalizer area, for example, classified by merchandise section, time zone, transaction, etc., inspection work for printing out the data of the totalizer area on recording paper, It has a function to selectively execute various tasks such as clearing tasks to clear the totalizer area after printing out the data on the recording paper, and has a mode switch as a means to selectively switch and set the task modes. are doing.

Recently, a model equipped with an external storage device such as a hard disk device has been developed and put into practical use for the purpose of saving transaction data and holding setting data. Then, in the conventional merchandise sales registration data processing device provided with this external storage device, the data in the totalizer area can be written and saved in the external storage device by a manual operation, for example, the totalizer area on the RAM due to a power failure or the like. Even if the data in the above is cleared, by restoring the data saved in the external storage device to the totalizer area, the data in the totalizer area will be restored to its original state to some extent (the extent to which it was written and saved by manual operation). There was something I could return to.

[0004]

However, in the conventional product sales registration data processing device of this type, the manual operation for saving the data of the totalizer area in the external storage device is complicated, and therefore the operator Feel burdened,
The reality is that the data in the totalizer area is not frequently stored in the external storage device. Therefore, even if the data saved in the external storage device is restored to the totalizer area because the data in the totalizer area has been cleared, only the old data remains in the external storage device. In most cases, it could only be restored to a state far from it.

The present invention has been made under such circumstances, and an object of the present invention is to make it possible to automatically and frequently store data in the totalizer area in another storage medium. It is intended to provide a sales registration data processing device.

[0006]

The present invention selectively switches and sets various business modes including a registered business mode in which the sales data of each product registered for sale by the product registration means is cumulatively stored in a totalizer area. In a merchandise sales registration data processing device having a mode switch, at least when the mode is switched from the registered business mode to another business mode by the mode switch, the data in the totalizer area is backed up in another storage medium. The above problems are solved.

The present invention also provides a totalizer backup area formed on a non-volatile storage medium different from the storage medium forming the totalizer area, a switch changeover detection means for detecting a changeover operation of the mode switch, and Data in the totalizer area when the detection means detects the switching operation of the mode switch and determines the state of the switching operation every time, and when the determination means determines at least the switching from the registered business mode to another mode. Is provided in the totalizer backup area, and the above-mentioned problem is solved.

By taking such means, when the mode switch is switched from at least the registered business mode to another business mode, the data in the total area is automatically stored in the total backup area of the non-volatile storage medium. As it is written, the data in the totalizer area is backed up frequently without burdening the operator.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a main part configuration of a POS terminal embodying the present invention. This POS terminal has a CPU (central processing unit) 1 as a control unit main body. A ROM (Read Only Memory) 2 in which fixed data such as a program is stored in advance in the CPU 1, a RAM 3 in which various memory areas for temporarily storing variable data are formed, a clock for clocking the date and time Various input / output devices such as a circuit 4, a host interface 5 for controlling transmission / reception of data to / from a higher-order host device (not shown) through a line, a keyboard 6, a display 7, a printer 8, and a HDD (hard disk device) 9. 6a, 7a, 8 for controlling the
A, 9a, I / O port 10 and other parts are connected by a bus line 11 such as an address bus and a data bus to form a control circuit.

As shown in FIG. 2, the I / O port 10 controls power on / off and various work modes such as “registration”, “return registration”, “inspection”, and “payment”. A signal from the mode switch 12 for selectively switching and setting is input. In addition, the I / O
A drive signal is output from the port 10 to a drawer opening device 13 that automatically opens a drawer (not shown) for accommodating cash or the like.

The mode switch 12 is rotated by a key, and the signal corresponding to the key position is I / O.
It is input to the port 10 and the CPU 1 uses this I / O port 1
The key position of the mode switch 12 is determined by the input signal to 0, and the program of the selected work is executed. Here, as shown in FIG. 3, the RAM 3 is formed with a mode flag table 31 storing mode flags F (F1, F2, ...) Corresponding to codes C for identifying each key position. Each time the CPU 1 detects the switching operation of the mode switch 12, the CPU 1 sets the mode flag F of the code C corresponding to the selected key position to "1", and the mode flag of each code C corresponding to the other key position. F
Is reset to "0".

Incidentally, the "registration" means the keyboard 6
The sales data such as the number of items sold and the sales amount of each product registered for sale based on the key input etc. are added and registered in the totalizer area formed on the RAM 3, and the product name and sales of the registered product are displayed on the display 7. When the amount of money, etc. is displayed and output, and the end of registration of one transaction is declared by pressing the closing key on the keyboard 6, the printer 8 issues a receipt on which detailed data of all the products registered for sale in the transaction and total data thereof are printed. This is the mode of business to be performed. In addition, the "return registration"
Is a mode of business in which the sales data of each product registered for sale is subtracted from the totalizer area and registered as in the case of the "registration" business. Then, the “registration” operation is executed when the customer pays for the purchased product, and the “return registration” operation is executed when the registration of the product returned by the customer or the registration error of the product is canceled.

On the other hand, the "inspection" is a business mode in which the printer 8 prints out the data accumulated and stored in the totalizer area as an inspection report on the recording paper. In addition, "settlement" is a mode of business in which data in the total area is printed out as a settlement report and then the total area is cleared, as in the case of "inspection". And in general,
"Inspection" work is performed regularly during business hours of the day,
The “payment” operation is executed only once after the end of the day.

Here, in the totalizer area, as shown in FIG. 4, product sales data by departmental totalizer 41, 1 transaction payment method for accumulating and storing product sales data for each department code for classifying each product. Transaction-based totalizer 4
2. It is formed on the RAM 3 by being classified into a time zone totalizer 43 or the like for accumulating and storing merchandise sales data for each traded time zone.

On the other hand, the HDD 9 is a storage medium (RAM 3) forming the totalizer areas 41, 42, 43, ....
It is a non-volatile storage medium different from that used for storing transaction data, storing setting data, and the like. In addition, as shown in FIG.
A totalizer backup area 51 is provided in which the data 2, 43, ... Can be written together with the date and time data.

The POS terminal starts up when the power switch (not shown) is turned on with the key position of the mode switch 12 in the "pause" state, and the CPU 1 is program-controlled so as to execute the processing shown in the flowchart of FIG. Has been done. That is, when the power is turned on, the CPU 1 first
As ST (step) 1, initialization processing such as initialization of the RAM 3 is executed. Also, as ST2, the HD
The totalizer backup area 51 of D9 is cleared. Next, at ST3, the signal from the mode switch 12 input to the I / O port 10 is monitored, and the operation of the mode switch 12 is awaited. If it is detected that the mode switch 12 has been switched, the mode before switching is "pause" and not "registration", so that the key position after switching of the mode flag table 31 is set as ST7. After the mode flag (current mode flag) of the corresponding code is set to "1", the business process of this current mode is executed until the mode switch 12 is switched again.

After that, when it is detected that the mode switch 12 has been switched by the signal from the mode switch 12 input to the I / O port 10 in ST3 (switch switching detection means), the mode flag table 31 is read as ST4. From the state of the mode flag F1 of the code corresponding to the key position "registration", it is determined whether the business mode before the switching operation is "registration" (switching state determination means).

When the mode flag F1 of the code corresponding to the key position "registration" is set to "1", the business mode before the switching operation is "registration", so ST5 is set. In addition to reading the current date and time data which is being clocked by the clock circuit 4, the data in the various totalizer areas 41, 42, 43 on the RAM 3 are read out at ST6,
The total date and time data is written in the totalizer backup area 51 on the HDD 9 (totalizer data backup means).

Thereafter, in ST7, the mode flag (current mode flag) of the code corresponding to the key position after the switching operation of the mode flag table 31 is set to "1" and all other mode flags are reset to "0". If so, the business process in the current mode is executed until the mode switch 12 is switched again.

When the mode flag F1 of the code corresponding to the key position "registration" is reset to "0" in ST4, the business mode before the switching operation is not "registration", so ST7 Proceed to and the mode flag table 31
If the mode flag (current mode flag) of the code corresponding to the key position after the switching operation of is set to "1" and all the other mode flags are reset to "0", the mode switch 12 is switched again. Until this time, the business process of this current mode is executed.

In the POS terminal according to this embodiment configured as described above, for example, before the opening of a day,
When the power switch is turned on with the key position of the mode switch 12 set to “pause”, the totalizer backup area 51 of the HDD 9 is cleared. At this time, since the data in the totalizer areas 41, 42, 43 are cleared after the report output processing of the settlement operation on the previous business day, the contents of the totalizer backup area 51 are set in the totalizer areas 41, 42, 43.
It matches the contents of 42 and 43.

After that, when the store is opened and the operator clerk switches the key position of the mode switch 12 to "registration", the sales registration work of the product purchased by the customer becomes possible. In this sales registration business, sales data of registered products is accumulated in various totalizer areas 41, 42, 43 on the RAM 3 classified by product department, payment method, time zone, and the like.

Further, at a pre-designated inspection time during business hours, the operator clerk switches the key position of the mode switch 12 to "inspect" and executes the inspection work. At this time, in response to switching the key position of the mode switch 12 from “registration” to “inspection”, various totalizer areas 41,
The data of 42 and 43 are written and stored in the totalizer backup area 51 on the HDD 9 together with the current date and time data read from the clock circuit 4.

After that, when the inspection work is completed, the operator clerk returns the key position of the mode switch 12 to "registration" and restarts the product sales registration work. At this time, even if the key position of the mode switch 12 is switched from "inspection" to "registration", the data in the various totalizer areas 41, 42, 43 are not written in the totalizer backup area 51.

Thus, when the day's business is completed, the operator switches the key position of the mode switch 12 to "payment" and executes the payment operation. At this time, in response to switching the key position of the mode switch 12 from “registration” to “settlement”, the data in the various totalizer areas 41, 42, 43, together with the current date and time data read from the clock circuit 4, H
It is written and stored in the totalizer backup area 51 on the DD 9. In addition, various totalizer areas 41, 42, 43
The data of is cleared according to the end of this settlement work.

As described above, the PO in this embodiment is
In the S terminal, every time the mode switch 12 is switched from the registered business mode to another business mode, the data of various totalizer areas 41, 42, 43 are automatically written in the totalizer backup area 51 on the HDD 9 for backup. I am trying to do it. As a result, various totalizer areas 4
Since the data of 1, 42, 43 are updated mainly by the processing in the registered business mode, various totalizer areas 41, 42,
The latest data of 43 can be backed up to the totalizer backup area 51 at high frequency.

Therefore, even if the data in the various totalizer areas 41, 42, 43 is cleared due to some influence, the mode switch 12 is switched to the manager [MGR] mode in the same manner as in the conventional case. By selecting the restore job from the job menu in the mode by key input and executing it), by restoring the data stored in the totalizer backup area 51 to the various totalizer areas 41, 42, 43, various totalizers The data in the areas 41, 42, 43 can be returned to the state when the mode was previously switched from the registered business mode to another business mode. As a result, for example, when the data in the various totalizer areas 41, 42, 43 is cleared after the mode is switched from the registered business mode to another business mode, the state immediately before being cleared must be surely returned. You can

Even if the data in the totalizer areas 41, 42, 43 are cleared during the work in the registered work mode, at least the state in which the mode has been switched from the previously registered work mode to another work mode, that is, Since it is possible to return to a state very close to that just before clearing, it is only necessary to return to the state immediately before being cleared from the result of printing on the journal, etc., and various totalizer areas 41, 42, 43 can be restored in a short time. .

Further, various totalizer areas 41, 42, 43
Data is automatically backed up in the totalizer backup area 51 when the mode switch 12 is switched from the registered business mode to another business mode, so that the data in the various totalizer areas 41, 42, 43 are backed up. There is also an effect that the burden on the operator can be reduced without requiring any special operation.

Further, various totalizer areas 41, 42, 4
Since the backup date and time data is also recorded when the data of No. 3 is backed up, it is possible to easily confirm at what point in time the data stored in the totalizer backup area 51 is the backup data.

By the way, totalizer areas 41, 42, 43
The latest data can always be backed up by backing up each time the data in the mode is updated. However, in the POS terminal of this embodiment, the mode switch 12
The data in the totalizer areas 41, 42, 43 are backed up in the totalizer backup area 51 only when the registered business mode is switched to another business mode, and the data in the totalizer areas 41, 42, 43 are updated. I do not back up at the timing. This is because the total area 41, 42, 43 has a large amount of data, and it takes several tens of seconds to back up to the HDD 9. Therefore, if backup is performed for each update, it may be necessary for the shopper to wait. This is because it may cause trouble.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, various totalizer areas 41, 42, 43 are provided only when the mode switch 12 is switched from the registered business mode to another business mode.
Backed up to the totalizer backup area 51, the totalizer area 41,
The backup frequency may be increased by backing up even when the operation mode in which the data of 42 and 43 is updated is switched to another mode. Further, only a specific total area having a high degree of importance may be backed up. By doing so, it is possible to reduce the processing time required to back up the data.

Further, in the above embodiment, the HDD 9 is used as the storage medium forming the totalizer backup area 51, but the present invention is not limited to this, and an optical disc,
A non-volatile storage medium such as a magnetic tape may be provided with an area for backing up the totalizer data 41, 42, 43. Since the HDD 9 is used in recent POS terminals for storing transaction data, storing and holding setting data, etc., the combined use of the HDD 9 has an advantage of reducing cost.

The totalizer backup area 51 is PO
Instead of the HDD 9 with a built-in S terminal, it is formed on a nonvolatile storage medium such as an HDD mounted on a host device connected to the POS terminal via a line, and at least the mode is switched from the registered business mode to another business mode. At this time, the data in the totalizer areas 41, 42, 43 may be transmitted and output together with the terminal identification number to the host device for backup. In this case, since a plurality of POS terminals are line-connected to the host device, the host device can collectively back up the data in the total area of each POS terminal.

Further, in the above-mentioned embodiment, the structure is such that the operation mode is selectively switched and set by rotating the mode switch 12 with the key, but the structure and the form of the mode switch are particularly limited. Not a thing. Of course, various modifications can be made without departing from the scope of the present invention.

As described above in detail, according to the present invention,
It is possible to provide a product sales registration data processing device capable of automatically and frequently storing data in the totalizer area in another storage medium.
