DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receipt journal printer for a merchandise sales data processing apparatus.

[0002]

2. Description of the Related Art A receipt journal printer provided in a merchandise sales data processing device such as an electronic cash register prints various data corresponding to a registration process on receipt paper or journal paper as characters. Such a receipt journal printer issues a receipt for printing characters on receipt paper for a customer, and a journal for printing and outputting characters on journal paper is stored for a store.

[0003] Such a journal not issued to the customer is disclosed in Japanese Patent Application Laid-Open No. 5-138953, since it is required to reduce the paper consumption rather than to improve the visibility. As described above, the present applicant has proposed that a journal character having a print size smaller than that of a receipt character be set separately from the receipt character.

[0004] In this manner, the character of the receipt has a good visibility because the print size is normal, and the consumption of paper can be reduced because the character of the journal has a small print size.

[0005]

In the above-described receipt journal printer, a dedicated character having a different print size is set between the receipt and the journal, so that the consumption of journal paper can be reduced without impairing the visibility of the receipt. Is to be reduced.

[0006] Here, the print size of the character of the receipt issued to the customer is inevitably determined in order to secure good visibility, but the print size of the character of the journal used in the store is determined by the size of the store. Depends on request.

That is, in a store where journals are frequently used, it is desirable that the visibility of the character be good even if the amount of journal paper consumed is ignored. It is desirable to reduce the consumption of journal paper even if the visibility of the document is reduced, and some stores demand a balance between such situations. However, in the above-described receipt journal printer, since the print size of the journal is fixedly set to one type smaller than the print size of the receipt, it is difficult to sufficiently respond to the above-mentioned market requirements.

In addition, in the above-described receipt journal printer, dedicated characters having different print sizes are set for the receipt and the journal. Therefore, the storage capacity of a CG (Character Generator) for storing these characters is a normal capacity. The productivity and miniaturization and weight reduction are hampered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. First, a printer unit 1 which is a receipt journal printer exemplified in this embodiment is a part of an electronic cash register 2 which is a merchandise sales data processing device as illustrated in FIG. The electronic cash register 2 has a CPU (C) that executes various data processing.
ROM (Read Only Memory) in which various data such as an OS (Operating System) is fixedly stored in advance in a system bus 4 for transmitting various data to an central processing unit (3).
5, a random access memory (RAM) 6 for printing and storing various data such as print data in an updatable manner, a keyboard 7 for inputting various data by manual operation, and a barcode scanner 8 for reading and scanning a barcode (not shown). A display 9 for displaying and outputting various data, a drawer unit 10 for storing money (not shown), a CG 11 in which characters are fixedly stored in advance in dot font pattern data,
Line heads 12, 13, feed motors 14, 15,
The structure is such that the cutter motor 16 and the like are connected.

Therefore, here, one receipt printer 17 is provided by a paper transport mechanism (not shown) having the line head 12 and the feed motor 14 and a cutter mechanism (not shown) having the cutter motor 16. The journal printer 18 is formed as a single unit by a paper transport mechanism (not shown) including the line head 13 and the feed motor 15.

The printer unit 1, which is a part of the electronic cash register 2, is composed of, for example, the CPU 3, the ROM 5, the RAM 6, the CG 11, and the receipt / journal printers 17, 18. Here, the RAM 6 functioning as a part of the printer unit 1 has a work area 19 for temporarily storing print data sequentially generated by the CPU 3 corresponding to the registration process.
Or print size specification to specify character print size
A flag area 20 in which a flag (not shown) as a means is set is formed.

In this printer unit 1, as shown in FIGS. 1 to 4, the print size of the character in the journal printer 18 corresponds to a flag previously set in the flag area 20 of the RAM 6. Size changing means for reducing the print format of the journal printer 18 in accordance with the print size of the character reduced by the size changing means.
And the RAM 6 and the like.

That is, in the printer section 1, FIG.
As illustrated in (a), the character that prints out on the receipt paper 21 by the receipt printer 17 and forms the receipt 22 is one type of “large” whose print size cannot be changed. As shown in FIG. 3B and FIG.
There are three types of characters which are printed out and form the journal 24, "large / medium / small" in which the print size can be selected.

In such a configuration, in the printer unit 1 of the electronic cash register 2, the print size of the character of the journal printer 18 is two steps from the standard "large" to "medium / small" as described above. It can be reduced to any size, but it is initially set to the standard "large" when the product is shipped. Therefore, if it is desired to change the print size of the journal printer 18 to “medium” or “small”, the flags are initially set in the three flag areas 20 of the RAM 6 by manual operation of the keyboard 7.

The operation control for executing the registration processing in the electronic cash register 2 in which the print size is initially set as described above will be described below with reference to the flowchart of FIG. First, the CPU 3 of the electronic cash register 2 stores the product data input by the clerk using the barcode scanner 8 or the keyboard 7 in the work area 19 of the RAM 6.
And execute registration processing (step P
1) The product name, unit price, and the like corresponding to this registration process are displayed and output on the display 9 (step P2). Therefore,
When the store clerk having completed such product control by repeating the operation control on the electronic cash register 2 and inputting the closing operation with the keyboard 7, the CPU 3 which has detected the closing operation ends the registration process and starts the closing operation ( Step P3).

Therefore, the CPU 3 of the printer unit 1
The print data for the receipt printer 17 is generated by, for example, editing the storage contents of the work area 19 of the RAM 6 (step P4), and the flag in the flag area 20 of the RAM 6 is read to set the print size of the journal printer 18 to "large. (Small / Small) (Step P5
6, 7). If the print size of the journal printer 18 is determined to be "medium" or "small" in steps P6 and P7, the print data generated in step P4 is processed into each print size in a predetermined print format ( Steps P8, 9).

The CPU 3 of the printer unit 1
If it is determined in step P5 that the print size of the journal printer 18 is "large", the print data generated in step P4 is transferred to the receipt printer 17 and the journal printer 1.
8 and if the print size of the journal printer 18 is determined to be “medium” or “small” in steps P6 and P7, the print data generated in step P4 is sequentially transmitted to the receipt printer 17 and , Step P8,
The print data processed in step 9 is sequentially transmitted to the journal printer 18 (step P10).

Then, the CPU 3 of the electronic cash register 2 drives the receipt printer 17 and the journal printer 18 with the print data sequentially transmitted in step P10 to form the receipt 22 and the journal 24, and the printing operation is completed. Then, the operation control is completed and the operation returns to the initial state (step P11).

By doing so, the printer unit 1 of the electronic cash register 2 sets the character print size to "large" for the receipt 22 issued to the customer as illustrated in FIG. 2A. Therefore, the visibility is as good as the conventional one. On the other hand, the printer unit 1 of the electronic cash register 2 determines that the journal 24 for record of the store changes the print size of the character to "1" as shown in FIG. It is possible to secure visibility by setting "Large"
As illustrated in FIG. 3B and FIG. 3C, the print size of the character is set to “small” to reduce the consumption of the journal paper 23, and as illustrated in FIG.
By setting the print size of the character to "medium", it is possible to implement a good balance between ensuring the visibility and reducing the consumption of the journal paper 23.

In addition, as shown in FIG. 3A, when the print size of the character is set to "large", the printer unit 1 of the electronic cash register 2 has the same print format as that of the receipt 22. For example, "change $ 4,567" and "check $ 5,000" are printed out in two lines. However, as shown in FIGS. When "medium" or "small" is set, the print format is also changed.
The change is printed and output in one line such as "¥ 4,567".

By doing so, the printer unit 1
Can compress the print area more effectively than simply reducing the print size of the character, and even if the character string is edited to reduce the number of lines as described above,
Since a series of character strings that are continuous in content are controlled so as not to be broken in the middle, the visibility of the printed content is not hindered.

Further, in the printer section 1, since the print size of one type of character stored in advance in the CG 11 is reduced as described above, a character having a plurality of types of print sizes is stored in the CG 11 in advance. There is no need to keep this in mind, and the character print size can be reduced to a plurality of types without increasing the storage capacity of the CG 11.

Also, in the printer unit 1 which is the receipt journal printer of the present embodiment, the print size of the character set in the dot font is reduced to two steps by the existing data processing such as the thinning process. The present invention is not limited to the above embodiment. For example, it is also possible to reduce the print size of a character set with an outline font or a vector font in a substantially stepless manner (not shown) by arithmetic processing. .

Further, in the printer unit 1 which is the receipt journal printer of this embodiment, the print size of the character is reduced equally in both the vertical and horizontal directions.
The present invention is not limited to the above embodiments. For example, the character print size may be reduced only in the vertical direction to reduce the line spacing (not shown), or may be reduced only in the horizontal direction to reduce the character spacing. Shortening (not shown) is also possible.

In this embodiment, a printer unit 1 which is a receipt journal printer is formed integrally with an electronic cash register 2 which is a merchandise sales data processing device. However, the present invention is not limited to the above embodiment. For example, a receipt journal printer having a unit structure detachable from an existing apparatus main body of a merchandise sales data processing apparatus may have a CPU or a dip. Providing size changing means with a switch (not shown)
Alternatively, it is also possible to dispersely provide each unit of the size changing means in both the apparatus main body of the product sales data processing apparatus and the receipt journal printer having a unit structure (not shown).
