Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a receipt printing method for an electronic register.Generally, in a printing device for an electronic register, the print head is arranged in a direction of 1-1 in the paper feeding direction of the receipt paper. Because it is located a considerable distance (for example, 4 lines of printing) behind the installation position of the cutter that cuts the receipt paper, the receipt paper cannot be cut after a transaction-specific key such as the cash key that ends the transaction is operated. It is necessary to feed the paper to the cutter position. Since printing starts from the print head position, sales data for the next transaction will be printed in the area between the cutter and the print head, in other words, on the receipt issued to the next customer. The leading area is a blank area where no sales data is printed. For this reason, in the past, information such as a store name was printed using a stamp using the blank space.

[Problems with conventional technology]

However, since the information printed in the blank area is stamp printing, the type of information printed is limited to store names, etc., and cannot be easily changed. Furthermore, because the size of the stamp, that is, the distance between the cutter and the print head is limited, the number of lines of information that can be printed on the stamp is limited.

2- [Object of the Invention] This invention was made against the background of the above-mentioned circumstances, and its purpose is to print on the head area of the receipt regardless of the distance between the cutter and the print head. To provide a receipt printing method for a child register which can greatly increase the number of data to be printed and can print without waiting for the next registration operation even if the number of data to be printed is increased.

[Key points of the invention]

In order to achieve the above-mentioned object, this invention provides a memory that stores in advance the head data to be printed in the leading area of the receipt, and when feeding the receipt paper to the cutter position at the end of registration, the data in the memory is The gist of the present invention is that a part of the data is printed at the same time as the paper is fed, and the remaining data in the memory is printed after the receipt paper is cut.

〔Example〕

Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings. In the figure, reference numeral 1 denotes a key input section, which is provided with numeric keys for inputting amounts, etc., department keys for specifying product departments, transaction keys such as cash keys, lending keys, etc. Key human power data output from the key human power unit 1 in correspondence with the operation keys is input to a CPU (central processing circuit) 2.

The CPU 2 controls various operations according to microinstructions stored in advance, and includes a control section 2-1, an arithmetic section 2-2, x, y, and z registers for arithmetic operations, and F for storing flag data. It has a configuration including a G register, an a register for storing address data of the head memory 4, which will be described later, and a b register for counting a certain period of time. Thus, the CPU 2 is connected to the total memory 3 and the head data memory 4 in the respective directions.

Total memory 3 and head data memory 4 are each SRA
M (Random Access Memory)
1. Write and read operations are performed under the control of CPU2. The total memo IJ 3 is for storing total sales data by department, transaction, etc., and the head data memory 4 is for storing total sales data by department, transaction, etc., and the head data memory 4 is for storing total sales data by department, transaction, etc., and the head data memory 4 is for storing total sales data by department, transaction, etc., and the head data memory 4 is for storing total sales data by department, transaction, etc. head data to be stored in advance. In this embodiment, it is possible to preset data arbitrarily inputted from the key input section 1 into the head data memory 4, and the data is preset in the head data memory 4 in the row address area of addresses 0 to 2 and the row address 4.5 with one row left. A series of comment data is stored in each address area, store name data is stored in the line address area at address 7 with one line left open, and an END code is stored in the line address area at address 9 with one line left open.

Further, the CPU 2 outputs display data to the display unit 5 to digitally display amounts, etc., and outputs print data to the printing unit 6 to print sales data and the like on receipt paper and journal paper. On the other hand, the printing section 6 outputs a small detection signal SP indicating whether or not the receipt paper has been cut, and inputs it to the CPU 2.

Next, the configuration of the printing section 6 will be explained with reference to FIG. The printing section 6 is composed of, for example, a top printer, and a print head 12 is disposed near the platen 11.

The print head 12 is located behind the cutting edge of the cutter 13 by four printing lines with respect to the paper feeding direction a of the receipt paper R,
A recorder 12a1 and an ink ribbon 12b are provided at the tip thereof. The cutter 13 is rotatably supported around a support shaft 14, so that when the receipt paper R is cut by the cutter 13, it is pushed by the receipt paper R and rotates in the direction indicated by the arrow in the figure (clockwise). It has become. A microswitch 15 is disposed near the lower end of the cutter 13, and the microswitch 15 is turned on by clockwise rotation of the cutter 13. The 0N10FF signal of this microswitch 15 is the detection signal S
Sent as . Note that 16 in the figure indicates a case of the printing section 6.

Next, the receipt printing operation of the m child register configured as described above will be explained. - When the transaction registration is completed and the transaction-specific key is operated, the operation according to the flow shown in FIG. 3 is executed. First, in step SI, a transaction registration process corresponding to the type of the operated transaction key is executed, and the total amount of the transaction, etc. is calculated. This total amount, etc. is displayed by executing the next step S2, and
Printing is performed by executing the next step S3. in this case,
Simultaneously with the printing operation, a paper feeding operation is performed to feed one line of the recording paper F. Next, the process proceeds to step &, where a yes process is executed to clear the contents of the a register and the b register. Thereafter, a process of sequentially printing the contents of the head data memory 4 on receipt paper is executed. That is, in step S5, the content M(a) of the head data memory 4 addressed by the content of the a register is transferred to the X register. And next step S.

Then, it is determined whether the contents of the X register are an END code. Initially, the row address at address 0 of the head data memory 4 is specified, and the contents stored in the address area are transferred to the X register, so step S
In this case, the answer is "NO" and the process proceeds to the next step S7. Here, the contents of the X register are sent to the printing section 6 to be printed on the receipt paper R, and in conjunction with this printing operation, the receipt paper R is fed by one line. Next, step S8
Then, the process proceeds to increment the contents of the a register by 1, and updates the address section of the head data memory 4. As a result of this address update, in the next step S, it is determined whether the contents of the a register are 4 or more or less than 4. That is, the above step S determines whether or not the receipt paper R has been fed from the printing position of the print head 12 to the cutting edge position of the cutter 13, in other words, the row address area of addresses 0 to 2 in the head data memory 4. In the process of detecting whether or not the content stored in has been printed on the receipt paper, if it is determined that the number is less than 4,
Returning to step S, the operation of sequentially printing the data in the head data memory 4 is performed in the same manner as described above. On the other hand, if it is 4 or more, the process advances to the next step S18, where it is determined whether the flag data stored in the F register is PI, II or IT OII. - In this case, the F register stores the status 7 and lag indicating whether or not the receipt paper has been cut. In this embodiment, it is 0" in the state before it is cut and 1" in the state after it is cut. flag is now set. If the contents of the F register are now 0'', proceed to the next step S11 and return to 1''.
If so, return to step S.

In step Sl+, the microswitch 15 is turned on or off in accordance with the detection signal S from the printing section 6. In other words, when the receipt paper R is cut off by the counter 13 in the printing section 6, the cutter 13 is turned on or off in accordance with the detection signal S from the printing section 6. Since the microswitch 15 is turned on by the rotation, it is a process to judge whether the receipt paper R has been cut or not. If the receipt paper is cut off, the process proceeds from step S1+ to step 812, sets a flag of 1' in the F register, and then returns to step S6. As a result, after the receipt paper is cut out, the remaining data in the head data memory 4 is printed. If all the data in the head data memory 4 has been printed in the leading area of the receipt paper and the END code in the head data memo=9- 4 is detected in step s6, the process goes to step 813. Advance and set flag ``0'' in F and G registers respectively.
After the process of setting is executed, the process associated with the operation of the transaction-specific key ends.

FIG. 4 (A"l and 0 are the print formats in this case). FIG. 4 (A) shows the print position PL corresponding to the recording needle 12a of the print head 12 by operating the transaction key after registration This is the printing state when the paper is fed from CL to the cutting position CL corresponding to the cutting edge of the cutter 13. In this case, between the cutting position CL of the receipt paper and the printing 1tPL, the rows at addresses 0 to 2 of the head data memory 4 are A series of comment data stored in the address area is printed.
Figure (B) shows the printing state when the receipt paper is cut out. In this case, by continuing the printing operation of the head data, the remaining data in the head data memory 4, that is, the 4. A series of comment data stored in the line address area at address 5 and store name data stored in the line address area at address 7 are printed.

-1〇- On the other hand, if the receipt paper is not cut, it is determined to be "OFF" in step S1□, and the next step 8
14. Here, the contents of the b register are +1
Then, in the next step ski, it is determined whether the content of the b register is less than a predetermined value N or not.
A determination is made as to whether the number is N or more. If the value is less than N, the process returns to step S1, and the above-described operation is repeated until the contents of the b register become equal to or greater than N. That is, steps SS+ and S16 are processes for detecting whether or not the receipt paper has not been cut out for a predetermined period of time. If the receipt paper has not been cut out, the process proceeds to the next step Sta, and after setting the flag l11II in the G register. , the process associated with the transaction-specific key operation ends. Therefore, in this case, printing of the remaining data in the head data memory 4 is not executed.

When the numeric key is operated for the next transaction registration operation, the process proceeds to step SI7, and the input sales data is
Processing to place a number in a register is executed. Then, the process advances to the next step 818, and the data placed in the X register is displayed. Therefore, in the next step SIQ, it is determined whether or not it is the first digit, and if it is the first digit, the next step 8
Proceed to step 20. This step S20 is a process for determining whether the contents of the G register are 0'' or 11''. If it is not printed, proceed to step 812 described above, set the flag "1" in the F register, and then return to step S. Due to kneading, the head that did not print due to the previous transaction key operation The remaining data in the data memory 4 will be printed on the receipt paper at the first hundredth number associated with the next registration operation.In other words, if you forget to cut out the receipt paper and start the registration operation for the next customer. However, all the data in the head data memory 4 can be sequentially printed in the first area of the receipt.

Note that the present invention is not limited to the above-described embodiments, and can be modified and applied in various ways without departing from the scope of the present invention.

For example, in the above embodiment, the receipt paper is cut manually, but it may be equipped with an auto-cut function, and the printing unit is not limited to a dot printer, but may be a type printer, etc. good.

〔Effect of the invention〕

As described in detail above, this invention provides a memory that stores in advance the head data to be printed in the leading area of the receipt, and when feeding the receipt paper from the printing position to the cutting position at the end of registration, A part of the data in the RAD data memory is printed sequentially as the paper is fed, and when the paper is not fed to the cutting position, the printing operation is stopped, and when it is detected that the receipt paper has been cut, the printing operation is stopped. Since the head data is continuously printed, it is possible to print head data even in areas that exceed the distance between the cutter and the print head, and the number of head data prints can be greatly increased regardless of the print head position. In addition, since the remaining head data is printed after the receipt paper is cut by increasing the number of head data prints, there is no need to wait for the next registration operation.
