Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sales data processing device such as an electronic cash register or a POS (Point of Sales) system.

[0002]

2. Description of the Related Art Generally, an electronic cash register (E
In CR), the registration result is printed out from the receipt printer and the journal printer every time the input sales data is registered, but the registration result is called a journal memory without mounting the journal printer. Stored in a relatively large capacity RAM in sequence,
An ECR that issues a journal report by sequentially printing out the contents of the journal memory at the end of business is commercialized. In this type of ECR, it suffices to mount one printer, which is extremely effective in reducing the cost. Note that the journal memory sequentially stores various data to be saved for business record, and stores setting data such as unit price change and contents of various totalizers in addition to the registered data.

[0003]

However, in this type of ECR, even with a relatively large-capacity journal memory, the larger the number of registrations, the larger the journal memory usage amount, and finally the allowable amount. , The journal memory may become full.
In such a case, even if a registration operation is performed thereafter, the registered content cannot be stored in the journal memory, so that data loss occurs in the recorded content of the journal memory. An object of the present invention is to effectively prevent data loss to the memory even when the memory that sequentially stores journal data becomes full.

[0004]

Means for Solving the Problems The means of the first invention is as follows. The data storage unit 1A (see the functional block diagram of FIG. 1A, the same applies hereinafter) is a RAM called a journal memory for sequentially storing various data to be saved for business records. The registration processing means 2A performs a registration process on the input sales data and writes the registered sales data in the data storage means 1A. The detection means 3A detects a full state in which a predetermined amount of data is written in the data storage means 1A. The full state means a full-end state in which data is written up to the final address of the data storage means 1A, as well as the final address. Including the near-end state in which data is written up to the address just before. The notification means 4A is a buzzer, a display device or the like for notifying that the full state is detected by the detection means 3A. The means of the second invention is as follows. The data storage means 1B (see the functional block diagram of FIG. 1B, the same applies hereinafter) is a so-called journal memory that sequentially stores various data to be saved for business records. The registration processing means 2B performs the registration processing of the input sales data and writes the registered sales data in the data storage means 2B. The detection means 3B detects a full state in which a predetermined amount of data is written in the data storage means 1B. When the detection means 3B detects the full state of the data storage means 1B, the processing control means 4B prohibits the processing by the registration processing means 2B and permits only other specific processing. In this case, the processing control means 4B permits the closing processing for terminating the registration of one transaction as a specific processing, or when the full state is detected by the detection means 3B during the registration of one transaction, it is registered before that transaction. The cancellation process for canceling the registered content is permitted as the specific process. The means of the third invention is as follows. The data storage means 1C (see the functional block diagram of FIG. 1C, the same applies hereinafter) is a so-called journal memory for sequentially storing various data to be saved for business record. The registration processing means 2C registers the input sales data and writes the registered sales data in the data storage means 1C. The detection means 3C detects the full state in which a predetermined amount of data is written in the data storage means 1C. When the detection means 3C detects the full state of the data storage means 1C, the processing control means 4C logically disconnects the data storage means 1C and the data storage means 1C.
In addition to prohibiting the writing of data to, a normal receipt is issued at the closing operation to end the registration for one transaction, and a journal report for that transaction is issued.

[0005]

The operation of the means of the first invention is as follows. Now, every time a product-specific registration operation or the like is performed, registration processing means 2A
Registers the input sales data and writes the registered sales data in the data storage means 1A. Here, when the detecting means 3A detects the full state of the data storage means 1A, the notifying means 4A gives a notification to that effect.
The operation of the means of the second invention is as follows. Now, each time a product-specific registration operation or the like is performed, the registration processing means 2B performs the registration processing of the input sales data, and also writes the registered sales data in the data storage means 1B. Here, when the detection means 3B detects the full state of the data storage means 1B, the notification means 4B prohibits the processing by the registration processing means 2B thereafter, and performs other specific processing (for example, the closing processing or the cancellation processing described above). Etc.) The operation of the means of the third invention is as follows. Now, each time a product-specific registration operation or the like is performed, the registration processing means 2C performs the registration processing of the input sales data, and also writes the registered sales data in the data storage means 1C. Here, the detection means 3
When the full state of the data storage means 1C is detected by C, the notification means 4C logically disconnects the data storage means 1C to prohibit the data writing to the data storage means 1C, and ends the registration for one transaction. A normal receipt is issued at the time of closing operation, and a journal report for the transaction is issued. Therefore, even if the memory for sequentially storing the journal data becomes full, it is possible to effectively prevent data loss to the memory.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 2 is a block diagram showing the structure of the ECR.
The CPU 11 has a calculation unit 11-1 and a control unit 11-2,
The CPU 1 controls the entire operation of the ECR according to various programs stored in the ROM 12.
1 includes an input unit 13 and a display unit 1 as its peripheral devices.
4, the printing unit 15 and the drawer 16 are connected and control their input / output operations.

The input unit 13 has various keys normally provided on its keyboard, that is, a numeral key AK, a clear key BK, a cash key CK, a department key DK, a subtotal key EK,
A rental key FK, a cancel key GK, and the like are provided, as well as a mode switch MS. In addition,
The cancel key GK is operated to cancel the registered contents of the transaction during registration of the transaction.
Further, the mode switch MS switches each mode of “setting”, “registration”, “power off”, “inspection”, and “payment” according to the switching position. In the registration mode in which the mode switch MS is set to the “registration” position, the sales data for each department input from the input unit 13 is displayed on the display unit 1.
It is output from the display unit 4 and printed from the printing unit 15, and is further registered in various totalizers in the RAM 17.
The printing unit 15 is composed of one printer, and only prints a receipt when registering a product.

The RAM 17 is provided with a journal memory 17-2, a flag register 17-3, a flag register 17-4, and a transaction buffer 17-5 in addition to various totalizers such as the departmental totalizer 17-1. . Journal memory 17
-2 is for storing journal data to be saved for business record, and the contents thereof are sent to the printing unit 15 and printed out at the time of settlement of the journal memory 17-2.
Cleared. On the other hand, the CPU 11 is the journal memory 1
7-2 is being used to monitor the usage amount, and the journal memory 17
-2, when a full state in which a predetermined amount of data is written is detected, an error notifying lamp (not shown) on the display unit 14 is turned on to inform that the journal memory 17-2 has become full. To do. In addition, the flag register 17-
3 is a flag register that stores a full error flag that is set when the departmental totalizer 17-1 is in a full state, and the flag register 17-4 indicates that the departmental totalizer 17-1 is in a full state. When it becomes, 17-
1 is a flag register that stores a disconnection flag indicating a logically disconnected state. One transaction buffer 17
-5 stores and holds sales data for one transaction, and the contents are cleared when the registration for one transaction is completed.

Next, the operation of this embodiment will be described. FIG. 3 is a flowchart showing the operation in the registration mode in which the mode switch MS is set to the "registration" position. First,
The CPU 11 refers to the contents of the flag register 17-3 to check whether the full error flag is set, that is, whether the journal memory 17-2 is in the full state (step A1). Journal memory 1 now
If 7-2 is not in the full state, the process proceeds to step A2, and it is checked whether the product registration operation has been performed. Here, when the divisional registration operation is performed in accordance with the normal key operation procedure, the registration process of registering the input sales data in the divisional totalizer 17-1 and the like is executed (step A3), and the registration result is obtained. Is written in the journal memory 17-2 in addition to the one transaction buffer 17-5 (step A4). As a result, the usage amount of the journal memory 17-2 increases, and it is checked whether or not the near end state (full state) close to the maximum capacity has been reached (step A5). If the full state has not been reached, step A1 is reached. Back, journal memory 1
If 7-2 has reached the full state, the error notification lamp of the display unit 14 is turned on (step A6) and the full error flag "1" is set in the flag register 17-3 (step A7). Then, returning to step A1, if the full-end flag is "0", the above operation is repeated every time the registration operation is performed. Then, when the registration of one transaction is completed and the finalize key such as the cash key CK is operated, the fact is detected in step A8, the process proceeds to step A9, and the closing process described later is performed.

On the other hand, when the full end flag is "1", the cash key CK, the finalize key such as the lending key FK (step A8) and the clear key BK (step A).
10) and the operation of only the cancel key GK (step A14) are permitted, and other operations such as product registration are prohibited. That is, when the full end flag is "1", the process proceeds to step A8, and it is checked whether or not the finalize key is operated. If the finalize key is operated, the closing process is performed (step A9).

FIG. 4 is a flowchart showing the tightening process in this case. First, it is checked whether or not the disconnection flag is "1" by referring to the contents of the flag register 17-4 (step B1). Here, the detachment flag indicates that the journal memory 17-2 is logically detached from the CPU 11 when the journal memory 17-2 is in the full state. If the detachment flag is "1", the process proceeds to step B3. Then, after the receipt is issued from the printing section 15, the contents of the one transaction buffer 17-5 are printed out from the printing section 15 (step B3). A journal report for the transaction is issued (step B4). Then, the process proceeds to step B5, the contents of the one-transaction buffer 17-5 are cleared, and then the process returns to step A1 in FIG. On the other hand, if the separation flag is "0", the finalized data is written in the journal memory 17-2 (step B6) and a receipt is issued (step B7), as usual. Then, the process proceeds to step B8, and one transaction buffer 17-5
After clearing the contents of, return to step A5 in FIG. In this way, the journal memory 17-2 is full,
If the journal memory 17-2 is logically separated, a normal receipt and a journal report for the transaction are issued.

On the other hand, when the clear key BK is operated, the fact is detected in step A10 and the process proceeds to step A11 where the contents of the flag register 17-3 are referred to and whether the full end flag is "1" or not is determined. To check. Here, if the full-end flag is "1", the error notification of the display unit 14 is canceled (step A12), and if the full-end flag is "0", other clear processing is performed as usual (step A12). A13). Further, when the cancel key is operated, the fact is detected in step A14, the process proceeds to step A15, the processing for canceling the registered contents in the current transaction is performed, and it is considered that the transaction has not existed from the beginning. It

When the full state of the journal memory 17-2 is detected in this way, the registration process is prohibited thereafter, and only the other specific process is permitted. That is, the closing process for ending the registration of one transaction (step A9), the clearing process accompanying the clear key BK (step A13) / the error notification canceling process (step A12), the cancel key GK
Only the cancellation process (step A15) associated with is permitted.

FIG. 5 is a flow chart showing the operation in the setting mode in which the mode switch MS is switched to the "setting" position. Now, if the full state of the journal memory 17-2 is confirmed by the error notification, an operation for designating the journal memory 17-2 in the setting mode is performed to logically disconnect the journal memory 17-2. When it is detected in C1, step C
3, the flag register 17-4 is referred to, and it is checked whether or not the disconnection flag is "1". If the disconnection flag is "0", the disconnection flag "1" is set in the flag register 17-4 (step C5).
As a result, the journal memory 17-2 is in a logically separated state. Also, the journal memory 17-
In the state where 2 is separated, the journal memory 17
2 is reconnected to the CPU 11 again, when the operation for designating the journal memory 17-2 is performed in the same manner as described above (step C1), the disconnection flag "1" is detected in step C3, so step C4 Then, the separation flag "0" is set in the flag register 17-4.
As a result, the journal memory 17-2 becomes reconnected. If the operation for designating the journal memory 17-2 is not performed, the process proceeds to step C2 and other setting processing is performed.

FIG. 6 is a flow chart showing the operation in the settlement mode in which the mode switch MS is switched to the "settlement" position. First, in step D1, the department totalizer 17-
It is checked whether the settlement for 1 is designated, and not the journal memory 17-2 but the section totalizer 17-1.
If, for example, the payment process is performed accordingly (step D7), if payment to the journal memory 17-2 is instructed, the process proceeds to step D2, and the journal header information (date and time, responsible person name, etc.) is stored. After being generated and printed out, the contents of the journal memory 17-2 are sequentially printed out (step D3). As a result, when the journal report is issued (step D4), the contents of the journal memory 17-2 are cleared (step D5). Then, "0" is set in the flag register 17-3 to set the full error flag to "0". In this way, the full error flag is turned off when the journal memory 17-2 is settled.

In the above embodiment, the journal memory 17 is used.
Although the full state of -2 is notified by turning on the lamp, it may be notified by a buzzer sound or the like. Further, the full state of the journal memory 17-2 is detected in multiple stages, and in the full state of the first stage, the registration process can be executed in the same manner as usual only by notifying that, and the full state of the second stage is registered. The processing may be prohibited.

[0017]

According to the present invention, even if the memory for sequentially storing journal data becomes full, it is possible to effectively prevent the loss of data in the memory, so that the journal data can be recorded and saved reliably. Therefore, it becomes extremely practical.
