Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a printing device that prints input item data in real time while adding line breaks for each item.

[Conventional technology] Conventionally, in electronic registers, etc., the input sales data for each transaction is printed on a new line for each item, and the authentication is printed in real time in the order in which it is input. This allows authentication to be performed almost simultaneously with the instruction to close the registration. There are known devices that complete printing and speed up processing.

In this case, the authentication slip is generally a predetermined size unique to the store.

[Problem to be solved by the invention] As described above, since the size of the authentication slip is standardized, the number of items for a transaction may exceed the maximum number of lines printed on the authentication slip. In this case, the information had to be printed on the back side of the authentication slip or printed on two authentication slips, leading to a decline in service.

This is because in order to adhere to the principle of the slip format that one item is printed per line, each item is printed with a new line, so the feed direction of the authentication slip is fixed. This is due to the fact that even if the size of the authentication slip is such that multiple items can be printed on one line, it is not possible to return to the line where printing has been completed.

If you can control the feed direction of the authentication slip in the forward or reverse direction, even if you print the sales data for each input transaction on a new line for each item and print the authentication slip in real time in the order in which it was input, it will only take one line. It is clear that multiple items can be printed.

The problem with this invention is that in a printing device that prints input item data in real time while adding line breaks for each item, when the number of item data exceeds the number of printable lines is input, the feed direction of the printing paper is The purpose of this invention is to enable printing of a plurality of items on one line by freely controlling the forward and reverse directions.

[Means to solve the problem] The means of this invention are as follows.

This printing device prints the input item data in real time while starting a new line for each item, and the foot means a (see the functional block diagram in Figure 1, the same applies hereinafter) prints the printing paper correctly. Feed in reverse.

The determining means determines whether or not the line to be printed on the printing paper exceeds the last line of the printing paper when the item data is input.

When it is determined by the determining means that the last line has been exceeded, the printing control means C feeds the printing paper in the reverse direction using the feeding means a, rearranges the line, and prints the input item data.

[Action Co. The operation of the means of this invention is as follows.

In the process of printing input item data in real time with line breaks for each item, the determining means determines whether, when item data is input, the next line to be printed on the printing paper is the last line of the printing paper. Determine whether the limit has been exceeded.

When it is determined by this determining means that the last line has been exceeded, the printing control means C, for example, causes the feed means a to move in the opposite direction from the previous line so that the first line is the next line to be printed. The printer feeds the printing paper, rearranges the rows, and prints the input item data.

Therefore, in a printing device that prints input item data in real time with line breaks for each item, when the number of item data exceeding the number of printable lines is input, the feeding direction of the printing paper can be freely changed in the forward or reverse direction. Multiple items can be printed on one line by controlling the

[Example 1] An example will be described below with reference to FIGS. 2 to 4.

FIG. 2 is a block diagram of an electronic register equipped with a printing device.
, a RAM 4, a display section 5, an R/J printing section 6, a slip printing section 7, and a drawer 8.
is configured so that the authentication slip can be fed in either the forward direction (discharge direction) or the reverse direction (intake direction).

The CPU performs various cumulative processing on the sales data input from the key input section 2 according to a program preset in the ROM 3, stores the cumulative processing results in the RAM 4, displays them on the display section 5, and displays them on the R/J printing section 6. to print the receipt.
Alternatively, it controls a series of registration processes such as authentication printing in the slip printing unit 7.

Note that both receipt printing and authentication printing are performed alternately in real time based on input data.

At this time, receipt printing and authentication printing are executed with a new line for each item, but authentication printing is performed as follows: - When the transaction data cannot be printed in one column on the authentication slip,
Printed in two columns. That is, if the maximum number of lines on the authentication slip is exceeded, the authentication slip is fed in the opposite direction to return to the first line, rearranged, and two items per line are printed.

The key input section 2 has settings (P), registration (R), power off (
○FF), mode changeover switch SW to change and set each mode of inspection (X), settlement (Z), sales quantity, PLUN
In addition to the numeric key 2a for entering numbers such as Q, the numeric key 2a
PLU indicating that the numerical value input in is PLUNQ
It has various function keys such as an Nα key 2b, a cash/deposit key 2C for instructing opening of the drawer 8, - transaction closing process, etc.

The RAM 4 includes a PLU-specific memory M1 that stores cumulative sales data for each PLU product, a format memory M2 that stores format information for executing authentication printing as described above, and a work memory M3.

All memos by PLU 9M1 The product name, unit price, number of units sold, and sales amount are stored in correspondence with each PLUNQ.

Among these, PLUNQ, product name, and unit price are preset in the setting mode, and the number of sold items and sales amount are updated based on the input of sales data in the registration mode.

The format memory M2 stores the maximum printable number of lines of the authentication slip, the leading digit position for the item in the first column, and the leading digit position for the item in the second column.

The work memory M3 is formed with a flag F for the 12th column of the counter C for storing the current line to be printed on the authentication slip, and a slip print buffer Bu.

It should be noted that each time all the processing for the - transaction is completed, the counter C is initially set to "1" and the second column flag F is reset. Further, authentication print data for one item is temporarily stored in the slip print buffer Bu.

Next, the registration process will be explained with reference to FIGS. 3 and 4.

Sales data for one item (PLUN) under registration mode
When the input PLUN (Q, quantity, etc.) is input, the CPU updates the sales quantity and sales amount of the corresponding product in the PLU-specific memory Ml based on the input data. The corresponding product name and unit price are read out from the entire memo 9M1 by PLU and stored in the slip print buffer Bu (step S2), and receipt printing and journal printing are performed in the R/J printing section 6 (step S3).

Next, it is determined whether or not the second column flag F is set (step S4). As a result, if the second column flag F is in the reset state, the first column item stored in the format memory M2 The print head (not shown) is shifted to the first digit position, and the product name and unit price in the slip print buffer Bu are printed from the first digit position (step S5).

The printed line at this time corresponds to the line number in the counter C, as will be clear from the explanation below.

On the other hand, if the second column flag F is set, the print head is shifted to the first digit position for the second column item stored in the format memory M2, and from that first digit position, the product name in the slip print buffer Bu is and the unit price (step S6: see FIG. 4).

Next, step S increments the line number in counter C by 1.
7), the contents plus 1 are the format memory M
It is determined whether or not the maximum number of lines that can be printed in 2 is exceeded (step S8). If the line number is exceeded, the line number in the counter C is returned to 1", and the second column flag F is set.
is set (step S9), and the authentication slip is fed in the opposite direction so that the first line becomes the next line to be printed (step 5IO).

On the other hand, if the maximum number of printable lines has not been exceeded, the authentication slip is fed one line in the forward direction so that the next line becomes the next line to be printed (step 511).

After feeding the authentication slip in this way, the contents of the slip print buffer Bu are cleared (step 512),
finish.

In this way, only when the authentication print data for a transaction cannot be printed in the first column of the authentication slip, the authentication slip is fed in the opposite direction to return the line to be printed to the first line, and the remaining lines are left in the second column. items are printed, so it is possible to print as much authentication print data for one transaction on one side of one authentication slip without breaking the principle of the slip format of printing one item per line as much as possible. become. Further, as described above, since the sales data registration process and the authentication printing are executed alternately, the authentication printing is completed almost simultaneously with the transaction closing instruction.

Note that when performing authentication printing on the second column, it is also possible to sequentially return to the first line from the last line without immediately returning to the first line as in the above embodiment. Further, the determination as to whether the maximum number of printable lines has been exceeded may be made by optically detecting the presence or absence of paper, predetermined marks, etc.

[Effects of the Invention] According to the present invention, in a printing device that prints input item data in real time with line breaks for each item, when item data exceeding the number of printable lines is input, , the feeding direction of the printing paper can be freely controlled in the forward and reverse directions, allowing multiple items to be printed on one line. More item data for one group can be printed on one side of printing paper.
