Abstract

PURPOSE:To reduce the power consumption and the noise by printing out journal data by a journal printer during the non-printing operation of a receipt printer to prevent the receipt printer and the journal, printer from being driven in parallel. CONSTITUTION:A CPU 1 detects the driving state of a receipt printer 6-1 to discriminate whether or not is printing a receipt and, if it is printing a receipt, the journal output processing is terminated. If it is not printing a receipt, the journal output processing is executed hereafter on condition that key operation is not operated in a set time set in the CPU 1. Thus, the power consumption and the noise are considerably reduced because both of the receipt printer 6-1 and a journal printer 6-2 are not simultaneously driven. When the next register operation is executed during journal printing, journal printing is interrupted to give priority to the register processing, and therefore, the register processing is not affected at all.

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 (ECR) or a POS (point of sales) system.

[0002]

2. Description of the Related Art Generally, an ECR is equipped with a receipt printer constituted by a thermal printer and a journal printer, and the sales data registered at the time of registration of the sales data is printed out from the receipt printer and concurrently with this. Then, it is printed out from the journal printer.

[0003]

As described above, in the ECR equipped with two thermal printers, the receipt printing and the journal printing are performed in parallel when the sales data is registered, and the power consumption increases. There is a drawback that noise is increased due to the operation of the mechanical portion such as paper feeding. Therefore, in the past, a large-scale memory called a journal memory was provided in addition to one thermal printer,
When registering sales data, the registered sales data is printed out as a receipt and stored in the journal memory in order, and the contents of the journal memory are printed out and a journal report is issued at the end of a day's business. It is known to have been made. However, this kind of machine requires a large amount of journal memory and
It takes a long time to print out the contents,
There was a problem that you could not get the journal report immediately at the end of business. An object of the present invention is to prevent a receipt printer and a journal printer from being driven in parallel even if they are provided with the printer.

[0004]

The means of the present invention are as follows. (1) The journal data storage means is a random access memory or the like for storing journal data, which does not need to hold a business record for one day, for example, and is a very small memory as compared with the conventional journal memory. (2) The first control means prints the sales data registered at the time of registration of the sales data to the receipt printer and stores the sales data as journal data in the journal data storage means. (3) The detecting means detects whether or not the receipt printer is performing a printing operation. For example, the detecting means detects the sales data at regular time intervals. (4) When the detection means detects that the receipt printer is not printing, the second control means reads the journal data in the journal data storage means and prints out the journal data.

[0005]

The operation of the means of the present invention is as follows. Now, for example, when a registration process of a certain product is performed according to a normal operation procedure, the registered sales data is printed out from the receipt printer and held as journal data in the journal storage means. Here, it is detected whether or not the receipt printer is in the printing operation, and when it is detected that the receipt printer is not in the printing operation, the sales data stored in the journal data storage means is read out. Then, it is printed out from the journal printer. Therefore, even if the receipt printer and the journal printer are provided, it is possible to prevent them from driving in parallel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram showing the configuration of ECR.
The CPU 1 is a central processing unit that controls the overall operation of the ECR according to various programs in the ROM 2, and the CPU 1 includes a key input unit 3, a timer 4, a display unit 5, a printing unit 6, a buzzer 7, an online other The interface unit 8, drawer 9, and RAM 10 are connected.

The key input unit 3 is for inputting sales data and various commands. On the keyboard, there are a numeric keypad AK, function keys BK, and a mode switch MS for switching various modes such as registration, settlement and inspection. It is provided. With the mode switch MS set to the registration mode, the CPU 1 operates the key input unit 3
The sales data input from is fetched and registered in the totalizer 10-1 in the RAM 10, and the registered sales data is output from the display unit 5 and the printing unit 6.

The printing unit 6 includes a receipt printer 6-1 and a journal printer 6 which are thermal printers.
-2, the CPU 1 prints out the registered sales data from the receipt printer 6-1 when registering the sales data, and stores the sales data as journal data in the journal memory 10-2 in the RAM 10. Further, the CPU 1 monitors whether or not the receipt printer 6-1 is in the printing operation in the registration mode. When it detects that the receipt printer 6-1 is not in the printing operation, it starts the time counting operation of the timer 4, The CPU 1 compares with a preset time set in the CPU 1, and the CPU 1 reads the contents of the journal memory 10-2 record by record on condition that no key operation is performed within this set time, and the journal printer 6-2. Print out from.

The RAM 10 has a totalizer 10-1 and a journal memory 10-2. The totalizer 10-1 constitutes a totalizer for each department and person in charge, and the journal memory 10-2 is for the journal memory 10-2. It stores and retains the journal data to be printed out from the journal printer 6-2. It does not need to retain one day's business record like the conventional journal memory, and is much smaller than the conventional journal memory. It is a memory.

Next, the operation of this embodiment will be described with reference to the flow charts shown in FIGS. FIG. 2 is a flowchart showing a registration process that is started every time sales data is input in the registration mode. First, when sales data is input from the key input unit 3 according to a normal operation procedure, the CPU 1 outputs the input sales data to RA.
The value is added to the adder 10-1 in M10 and registered (step S1). The sales data thus registered is printed out from the receipt printer 6-1 (step S2) and stored in the journal memory 10-2 in the RAM 10 (step S3). That is, only the receipt is printed when the sales data is registered, and the journal printing data is held in the journal memory 10-2. Next, the CPU 1 executes the journal output process (step S
4) is performed. This journal output process is performed according to the flowchart shown in FIG.
Output from 2.

That is, the CPU 1 is the receipt printer 6-1.
Drive state is detected to determine whether printing is currently in progress or non-printing is in progress (step S11). If printing is in progress, this flow is exited and the journal output process ends (step S11). If printing is in progress, the time counting operation of the timer 4 is started (step S12). Next, it is checked whether or not there is a key operation from the key input unit 3 (step S13), and if there is, the flow is left as it is,
The journal output process is forcibly terminated, but if there is no key operation, the timer time read from timer 4 and CP
The set time preset in U1 is compared (step S14). As a result, if the timer time is less than the set time, the process returns to step S13 to check the presence / absence of key operation. Now, when it is detected that the timer time has reached the set time and no key operation is performed during the set time, the process proceeds to the next step S15, and the time counting operation of the timer 4 is stopped to clear the content.

As described above, if the key operation is not performed during the set time set in the CPU 1 while the receipt printer 6-1 is not printing, the journal output process is executed under the condition. . First, the CPU 1 checks whether or not data is stored in the journal memory 10-2 (step S16), and if there is, reads the journal data for one row (one record) (step S17), The printer 6-2 prints it out (step S18). Then, the journal data is erased from the journal memory 10-2 (step S19). Next, the presence / absence of a key operation is checked (step S20), and if there is, the process is exited and the journal output process is forcibly ended. If there is no key operation, the process returns to step S16. Thereafter, the contents of the journal memory 10-2 are printed out line by line from the journal printer 6-2 until there is no journal data in the journal memory 10-2.

As described above, in this embodiment, only the receipt printer 6-1 is activated when sales data is registered, and the journal printer 6-2 is driven under a certain condition while the receipt printer 6-1 is not printing. In order to print the contents of the journal memory 10-2, the receipt printer 6-
1 and the journal printer 6-2 are not driven at the same time. Even if the journal printer 6-2 is driven with a time difference as described above, if the next registration operation is performed during the journal printing, the journal printing is interrupted,
Since the registration process is prioritized, it does not affect the registration process. In particular, for journal printing, when the receipt printer 6-1 is not printing and the operator is interrupting the registration operation to check the price of the product, or after operating the closing key that completes the registration of one transaction, This is done in the idle time before the registration for the next customer starts.

In the above embodiment, the journal printing is performed on condition that the timer time reaches the set time. However, when the tightening key such as a cash key is operated, the journal printing is started immediately. You may in this case,
Since the processing is suspended for money transfer after the tightening, it is possible to print the journal using the idle time. In the above embodiment, if there is a key operation during journal printing, it is interrupted. However, in the POS system, whether data for receipt printing is transmitted from another POS terminal during journal printing. Journal printing may be interrupted based on whether or not the printing is performed.

[0015]

According to the present invention, a receipt printer,
Even in the case where the journal printer is provided, it is possible to prevent them from being driven in parallel, so that it is possible to significantly reduce power consumption and noise, which is extremely practical.
