Description

The present invention relates to an electronic cash register equipped with a printer for printing out sales data and the like on a receipt.

[Prior Art] Generally, in an electronic cash register arranged in a store or the like, a product code, a sales amount, a sales quantity, etc. of a sold product are input via a keyboard or an input device such as a fixed type or a hand type barcode scanner. When the sales data is input, the sales data is cumulatively registered in the registration memory formed in the storage unit and is printed out on the receipt and the journal.

As a printer incorporated in such an electronic cash register, there is a line printer, for example. As is well known, this line printer has a plurality of digits and characters of several symbols formed on the outer peripheral surface of a cylindrical character type drum whose axial length is longer than a receipt and a journal width.
In addition, a hammer mechanism is provided facing the type drum, in which hammers for printing the characters of each digit on the receipt and the journal are arranged by the number of digits. And
The paper feed motor conveys the receipt and the journal in the gap between the type drum and the hammer mechanism in the direction orthogonal to the axis of the type drum. Then, while the type drum is rotated at a constant speed by the drive motor, the hammer of the digit is driven at the timing when the letter of the character (number) to be printed on the digit drum faces the receipt and the journal. Then, the target character is printed out on the corresponding digit of the receipt and the journal.

A general sales registration operation in an electronic cash register using such a line printer is executed according to a flowchart shown in FIG. 5, for example. That is, when the power of the apparatus is turned on, various initial processes are executed, and then the motor for rotating the type drum of the line printer is started. Then, when the input operation (department registration operation) of each sales data for each sale product is executed from the keyboard or the barcode scanner at P1, each sales data is cumulatively registered in the registration memory of the storage unit and the storage unit Stored as print data in the print buffer of. If the closing key is not operated at P2 immediately, the printing process for the data stored in the print buffer is started.
That is, the flag indicating the close key operation is released to 0,
After the receipt and the journal are fed by one line, the print data for one line which is printed out on the receipt and the journal is printed out by the line printer. Then, when the print operation of the print data for one line is completed and new print data is stored in the print buffer, or when the print data of this time cannot be printed in one line, the print data of the remaining lines Execute printing for.

Then, when the closing key on the keyboard is operated on P2, the input operation of sales data (department registration operation) for all products sold to one customer is completed, so processing such as total calculation is performed. Store the calculation result in the print buffer. If the flag is set to 1 and unprinted data exists in the print buffer at P3, the unprinted data is printed out after feeding the receipt and the journal by one line.

Since the processing such as total amount printing corresponding to the closing key operation is completed as described above, after confirming that the flag is set to 1 in P4, the receipt and the journal are fed by 9 lines. A line corresponding to the next customer is stamped on the receipt and the head position of the journal corresponding to the next customer at a position where nothing is printed by the line printer which has fed the paper by 9 lines. After that, on P5 with a line printer today's date, and
Predetermined items such as ECR (resist) No. that do not depend on the sales data are printed out over two lines. Then, after feeding the paper by two lines, only the receipt is cut by the cutter and discharged from the receipt issuing port.

Since the distance between the cutter position and the line printer position is quite large, the receipt is cut between the total amount printing position and the store name printing position.

[Problems to be Solved by the Invention] However, the electric cash register configured as described above still has the following problems.

That is, the printing speed of the printer and the corresponding paper feed speed of the receipt and the journal are fixed to a constant value. Therefore, if an attempt is made to increase the printing speed in order to perform high-speed printing, the paper feed speed will also increase and noise will increase. As a result, it is uncomfortable for customers and cashiers.

However, if the printing speed of the printer is limited to a certain value or less, the entire printing processing speed becomes slow, and the work efficiency of the entire sales registration work decreases.

According to the present invention, by increasing the print processing speed of the printer when a certain operation of the sales registration operation for one customer is completed, noise is suppressed during the sales data input operation period of each product, and An object of the present invention is to provide an electronic cash register capable of improving the work efficiency of sales registration processing.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention registers the sales data of each sale product input through the input device in the storage unit and prints it out on the receipt by the printer. In response to the closing key operation on the keyboard, after performing a predetermined closing key process including a printout of the total amount of money for one customer on the receipt, a predetermined item that does not depend on the sales data is printed on the receipt. Then, the electronic cash register for issuing a receipt is provided with a print processing speed increasing means for increasing the paper feed speed of the receipt and the print speed corresponding to the paper feed speed in the printer during the print output period of the predetermined items on the receipt. It is a thing.

In another aspect of the invention, the electronic cash register described above includes a print processing speed increasing means for increasing a paper feed speed of a receipt in the printer and a print speed corresponding to the paper feed speed in response to a closing key operation. It is a thing.

[Operation] With the electronic cash register configured in this way, when the cashier operates the closing key by key operation after the input operation of each sales data corresponding to all the products sold to one customer is completed, After the predetermined closing key processing such as calculation and total amount printing is executed, the paper feed speed and the printing speed of the receipt are increased in the printer. Then, with the increased printing speed, predetermined items such as the date and the ECR (registration) number which are not dependent on the sales data are printed. Therefore, the noise of the printer is suppressed during the input operation of each sales data that the customer is paying attention to,
The printing speed can be increased during the printing period of a predetermined item that is not directly related to the sales data, and the receipt issuing efficiency can be increased.

Further, according to another clarification, when the closing key operation is executed, the printing speed thereafter, including the total amount printing, increases. Therefore, the time required for the entire print output process can be further shortened.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In the RAM 13, a totalizer 13a for calculating the total price of each product sold to one customer, a registration memory 13b for accumulating the sales data of each input sales product for each department, a receipt and a journal in the line printer 16 Print buffer 13c for temporarily storing print data to be output to the printer, closing key 9
Is operated, and a flag area 13d for storing a flag indicating that the closing key process is started is formed.

The basic configuration of the line printer 16 is as described above, but in this embodiment, the rotation speed of the printing drum changes between the normal speed and the high speed by switching the motor speed. Then, in synchronization with the change in the motor speed, the speed of the paper feed motor for the receipt and the journal is automatically switched from the normal speed to the high speed. In addition, this speed switching
It is executed by sending a command from the CPU 10 to the printer control circuit 17.

Then, when the power of the apparatus is turned on, the CPU 10 is programmed to execute the sales registration operation for one customer according to the flowchart of FIG. The same parts as those in the flow chart of the registration process in the conventional electronic cash register described with reference to FIG. 5 are designated by the same reference numerals (P1 to P5), and a duplicate description will be omitted.

In the flow chart of FIG. 3, when the power of the apparatus is turned on, first, the motor of the type drum of the line printer 16 is started to rotate at the normal speed. Then, the sales data for each sale product is input from the keyboard 2 at P1, is temporarily stored in the print buffer 13c, and is printed out on the receipt and the journal at the normal speed by the line printer 16 in the processes from P2a to P4. .

Then, when the closing key 9 is operated at P2, the total amount of money and the like are printed out at the normal speed by the line printer 16 in the processing after P3.

After that, the rotation speed of the motor of the line printer 16 and the paper feed speed of the receipt and the journal are switched to high speed on P4a. Then, the receipt and the journal are fed by 9 lines at high speed. Then, after printing a stamp such as the store name, on P5a, use a line printer to print today's date and E
It prints out certain items such as CR (Registration) No. that do not depend on the sales data at high speed in one line. Then, after feeding the paper by two lines at high speed, only the receipt is cut by the cutter and discharged from the receipt issuing port 4.

With the electronic cash register configured in this way, when the cashier operates the closing key 9 after the input operation of each sales data corresponding to all the products sold to one customer is completed, After the predetermined closing key processing such as calculation and total amount printing is executed, the paper feed rates of the receipt and the journal and the rotation speed of the print drum in the line printer 16 are switched to high speed. And this fast and independent of sales data eg Date, E
Prescribed items such as CR (register) No. are printed. Therefore, the noise of the line printer 16 is suppressed during the input operation of each sales data that the customer is paying attention to, the printing speed becomes high during the printing period of the predetermined items not directly related to the sales data, and the receipt is issued. It takes less time. In this way, by increasing the print processing speed for receipts and journals during the sales registration process, it is possible to suppress the noise that makes customers uncomfortable and reduce the time required to issue a receipt, thus improving the overall sales registration process. Work efficiency can be improved.

FIG. 4 is a flow chart showing a sales processing operation in an electronic cash register according to another embodiment. The same parts as those in FIG. 3 are designated by the same reference numerals, and the description of the overlapping parts will be omitted.

In this embodiment, when the tightening key 9 is operated at P2, the flag in the flag area 13d is set to 1, and then immediately at P2b, the rotation speed of the motor of the line printer 16 and the paper feed of the receipt and the journal. Change the speed to high speed. Then, at P3a, print data such as the total amount of money stored in the print buffer 13c at P3a is printed at a high speed by the line printer 16 after feeding the receipt and journal by one line at a high speed. To do.

Therefore, thereafter, the paper feed of the receipt and the journal for 9 minutes, the date in P5a, the print output of the ECR (registration) number, and the paper feed of two lines are executed at high speed.

In the electronic cash register configured as described above, when the closing key 9 of the keyboard 2 is operated,
The printing speed including the printing of the total amount of money is switched to high speed. Therefore, when all the key operations are completed, the customer or the cashier increases the print processing speed and causes a little noise, but since the key operations are completed, the customer or the cashier does not notice much. Therefore, the time required until the receipt is issued can be further shortened, and the effects described above can be further improved.
