Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a print processing device in an electronic cash register.

Conventional technology When an operator accidentally presses a key and prints something other than what he or she wants when printing a report to create an inspection report or payment report, or prints settings to confirm setting items,
With conventional electronic cash registers, there was no way to stop this process midway. Even if you turn off the power, it will continue printing if you turn it back on, so you had to wait until all printing was completed.

Problems to be solved by the invention As a result, printing paper and time were wasted. This waste could not be ignored, especially in reports with a large number of printed lines. Furthermore, when creating a payment report, all data in the memory is usually cleared after printing is completed, which poses a major hindrance to subsequent operations.

SUMMARY OF THE INVENTION An object of the present invention is to provide a print processing device for an electronic cash register that can immediately cancel an undesired print operation even if an undesired print operation is set due to an erroneous key operation.

Means for Solving the Problems The print processing device for an electronic cash register according to the present invention is characterized in that a single key is placed at a position where one of the registration mode, first print mode, second print mode, and print stop mode is designated. a mode setter for storing the mode set by the mode setter at a time other than the printing operation; a first storage means for storing the mode set by the mode setter at a time when the printing operation is being performed; 2 storage means, a third storage means for storing data related to registration, a printer for printing the data stored in the third storage means, and the first storage means stored in the first storage means.
Alternatively, in response to the second printing mode, the printer starts a printing operation, reads out and prints a predetermined amount of data from the third storage means, and each time printing of this predetermined amount of data is finished, the second It is checked whether the printing stop mode is stored in the storage means, and if it is stored, an invalid mark is printed to stop the printing operation by the printer, and if it is not stored, the next print from the third storage means is Proceed to read a predetermined amount of data and print it.
When printing of all the data to be printed in the third storage means is completed, the printing mode stored in the first storage means is checked, and if the printing mode is the first printing mode, the third printing mode is checked. The present invention is characterized by comprising a control means for controlling to erase data stored in the storage means.

Operation The mode set by the mode setting device at times other than printing operations is stored in the first storage means. If the mode set in the first storage means is the first printing mode (corresponding to payment mode) or the second printing mode (corresponding to inspection mode), the mode is stored in the third storage means. The printer starts printing the data.

Data is printed in a predetermined amount (for example, one line) at a time, and the mode stored in the second storage means is checked each time printing of a predetermined amount of data is completed.

The second storage means stores the mode set by the mode setting device at the time when the printing operation is being performed. When the mode of the second storage means is the printing stop mode, an invalid mark is printed and the printing operation by the printer is stopped.

If the mode stored in the second storage means is not the printing stop mode, reading and printing of the next predetermined amount of data from the third storage means is continued.

When printing of all the data to be printed in the third storage means is completed, the mode stored in the first storage means is checked again, and if it is the first printing mode, the mode stored in the first storage means is checked again. The data in the storage means No. 3 is erased.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an overview of the electrical configuration of an electronic cash register. The electronic cash register is controlled by a central processing unit, preferably a microprocessor (CPU) 1.
CPU1 stores the program in ROM2,
It also includes a RAM 3 for storing setting data such as product categories, unit prices, and product name display codes, and cumulative registration data such as sales numbers for each product. Connected to the CPU 1 are a keyboard 4 for performing settings, registration, printing operations, etc., an alarm buzzer 5, a display device for various data such as a CRT display device 6, and a printer 7 for creating reports as input/output devices. There is.

FIG. 2 shows the arrangement of the keyboard 4. The keyboard 4 includes a mode setting key 11 for setting various operation modes, a numeric keypad 12 for inputting numerical data, a department key 13 and a function key 14 for inputting a product department.
is provided. In this embodiment, the operating modes set by the key 11 include off mode (OFF), registration mode (REG), and inspection mode (X).
and payment mode Z. The off mode is set when the printing operation is stopped midway, as will be described later. The registration mode is for performing normal registration operations, ie, registering the number of sales for each product. The inspection mode is for setting unit prices, printing for confirmation, and checking sales amounts. In this embodiment, for convenience, it is assumed that the sales amount is checked in the check mode. In inspection mode
The registered data in RAM3 is not cleared, but it is cleared in the payment mode. The function key 14 includes a deposit/account key. This key is operated when calculating the total of cash sales in registration mode, when calculating change, and when starting printing in inspection and settlement mode.

In the RAM 3, as shown in FIG. 3, two areas R1 and R2 are provided for storing set modes. Area R1 is for storing the mode set by the setting key 11 in the normal operating state. Area R2 is for storing the mode set after the start of the printing operation. Each area R1, R2 has a registration flag F1REG, F2REG that is set to 1 when the registration mode is set, and an inspection flag F1 that is set to 1 when the inspection mode is set.
X, F2X, and settlement flags F1Z and F2Z, which are set to 1 when the settlement mode is set, are provided, respectively. All of these flags are reset to 0 when off mode is set.

FIG. 4 shows the processing procedure of the CPU 1.
First, the state of the mode setting key 11 is read and the set mode is stored in area R1 (step 21). Next, it is sequentially checked whether flags F1X and F1Z are set to 1 (steps 22 and 23). Flag F1X, F
If both 1Z are 0, another mode (for example, registration mode) is set, so
The process moves to the set mode processing, for example, registration processing (step 36). If either of the flags F1X, F1Z is 1, if there is any key input (step 24), it is checked whether it is an input using the deposit/account key (step 25).
If the input is not by this key, the process moves to other processing (step 37).

If the deposit/account key is input, the process proceeds to a printing operation, and the first line at the beginning is printed on the receipt by the printer 7 (step 26). When one line of printing is completed, the state of the setting key 11 is read and stored in area R2 (step 27).
And flags F2REG, F2X of area R2,
It is sequentially checked whether F2Z is set to 1 (steps 28, 29, 30). If any one of these flags is set to 1, it is checked whether printing has been completed for all the data to be printed (step 31), and if not, the process returns to step 26 and data is written from RAM3. Next, data for one line to be printed is read out, and printing for that one line is performed. Similarly, the state of the setting key 11 is read into area R2, and the state of each flag is checked.

In this way, the state of the setting key 11 is checked every time one line is printed, and the flag F2REG,
As long as either F2X or F2Z is set to 1, data printing continues. When printing of all data is completed, the state of flag F1Z in area R1 is checked (step 32). This flag F1Z is 1
In this case, it is the payment mode, so the registered data in RAM 3 is cleared (step 33), the report is printed, and a printed receipt is issued (step 34). Step 3
If flag F1Z is 0 in step 2, RAM3 is not cleared and report completion is printed and a receipt is issued.

If the setting mode using the setting key 11 is changed to off mode during the printing operation, when printing of a certain line is completed and the state of the setting key 11 is read into area R2, flag F2 is changed.
REG, F2X, and F2Z all become 0. Therefore, since the answer is NO in any of steps 28 to 30, an invalid mark A is printed on the line next to the previously printed line on the receipt 15 as shown in FIG. 5 (step 35), and the process ends. After printing, the receipt 15 is issued. In this case, of course, RAM3 is not cleared.

In this embodiment, the invalid mark A is two broken lines. This invalidation mark A records and clearly indicates that the issued receipt is invalid.

In this embodiment, the setting key 1 is pressed for each line of printing.
Although reading of the state of 1 and checking of the mode are performed, it may be performed every time two or three lines, etc., or an appropriate group of print data is printed. Further, although printing for confirmation of setting items such as unit price is not shown, in this type of printing as well, if the off mode is set, the printing operation is immediately stopped.

Effects of the Invention As described above, according to the present invention, even if an undesired printing operation is set and started due to a mistaken key operation, the mode setting device can be set to the printing stop mode during the printing operation. By this,
The printing operation can be stopped immediately.
Therefore, waste of receipt paper and time can be prevented. Furthermore, since an invalidation mark is printed when the printing operation is stopped, it is clearly known that the receipt is invalid. Furthermore, since data in the third storage means is erased only when all printing is completed, troubles such as erroneous clearing of data in the memory can be prevented.
