2. Description of the Related Art In a conventional POS terminal device, a product name is input from a PLU (price lookup) table based on a product key input by key input or bar code input for each sales registration of each product. By searching the price and displaying the retrieved product name on the display device, the operator can confirm whether or not the entered product name is correct. These conventional PO
As an S terminal device, for example, there is one disclosed in JP-A-61-91764.

In the conventional method of displaying the product name on the display device of the POS terminal device, the range (position (row, column position) and number of digits (display character number)) for displaying the product name on the display device is fixed in advance. The size of the display characters displayed in the product display range is also fixed.

[0004]

As described above, the PO
The method of displaying the product name on the display device of the S terminal device is as follows.
In order to display display characters of a fixed size in the product display range that has been fixed in advance, if the number of digits in the product name exceeds the product display range, part of the product name will be cut off. There is a problem that the product name is displayed, and the product name cannot be confirmed correctly.

Further, for a product name whose number of digits exceeds the product display range, a name omitted in the number of digits that can be accommodated within the product display range is registered in the PLU table so that a part of the product name is displayed in a discontinued state. However, it is necessary to create the PLU table in consideration of the number of display digits in advance when creating the PLU table, which is troublesome and the name is omitted. There was a problem in that it could not be confirmed.

The present invention has been made in order to solve such a conventional problem, and the product name is not discontinuously displayed, and the display range of the product name whose number of digits exceeds the display range is also displayed. It is an object of the present invention to provide a POS terminal device that does not need to register the abbreviated name within the number of digits that can be stored in the POS terminal device.

[0007]

In order to achieve the above object, in the present invention, a PO for registering sales of a product is used.
In the S terminal device, a table storing at least a product name and a price corresponding to the product key, an input means for inputting the product key, a display device capable of displaying by a bitmap, and the input means A processing unit that searches the table based on the product key to perform product sales registration processing, and a product name searched from the table,
The display device is configured to include a display control unit that changes the size of a display character and displays the display character in accordance with a predetermined display range of the display device. In a preferred embodiment, the display control means compares the number of digits of the product name with the reference number of standard display characters displayed in the display range, and the number of digits of the product name is the reference number of digits. When it is larger than the standard character, the display character of the product name is reduced from the standard character in accordance with the display range. The display control means, when the number of digits of the product name is larger than the reference number of digits, further compares the display character of the product name with a second reference number of digits for dividing into a plurality of lines; When the number of digits of the product name is larger than the second reference number of digits, the display character of the product name is reduced according to the display range, and the display unit is divided into a plurality of lines for display. In a further preferred aspect, the display control means compares the number of digits of the product name with the reference number of standard display characters displayed in the display range, and the number of digits of the product name is less than the reference number of digits. In this case, means for enlarging the display characters of the product name from the standard characters according to the display range, and the product name according to the display range when the number of digits of the product name is larger than the reference number of digits. And a means for reducing the displayed characters of the standard characters from the standard characters.

[0008]

In the present invention, the digit number of the retrieved product name is compared with a preset reference digit number, and if the digit number of the product name is within the range of the reference digit number, the standard display character size is used. The product name is displayed. When the number of digits of the product name is smaller than the reference number of digits, the display character is displayed with the display character enlarged to the maximum size that can be displayed in the display range. When the number of digits of the product name is larger than the reference number of digits, the display character is displayed in a size reduced to the size displayed without interruption.

You may make it store 0.

FIG. 2 shows C by the control program 161.
It is a block diagram showing a function realized on PU140. As shown, the CPU 140 uses the keyboard 110
Alternatively, an input unit 141 for inputting data from the barcode input device 130, a product search unit 142 for searching the PLU table 162 based on the input product key,
A product data processing unit 143 that performs sales registration processing for the searched product, a display control unit 144 that performs display control on the display device 120, and a receipt printing device 150.
The print control unit 145 for controlling the print control.

In the product sales registration process of the POS terminal device, first, when a product key is input from the keyboard 110 or the bar code input device 130, the product key is sent to the product search unit 142 via the input unit 141. . The product search unit 142 searches for the product key 163 of the PLU table 162 based on the input product key to acquire the product name 164 and the price 165. The product data processing unit 143 performs sales processing based on the acquired product name 164 and price 165.

At that time, the acquired product name 164 and price 16
5 is displayed in a predetermined product display range on the display device 120,
The operator can visually confirm whether the entered product and the product identified by the search are the same. Also,
Display result of processing in product data processing unit 143 1
20 and the receipt printing device 150 outputs the receipt.

Next, the display processing of the product name by the display control unit 144 will be described with reference to FIGS. 3 and 4. Figure 3
3 is a flowchart showing the contents of display processing. First,
The display control unit 144 compares the digit number of the retrieved product name with a preset reference digit number (n1, n2) (step 3).
01).

The reference digit number (n1, n2) is set based on a standard display character of a certain size displayed in the product display range 121 of the display device 120. That is, the maximum number of digits n2 and the minimum number of digits n1 displayed in the product display range 121 by standard display characters are set as the reference number of digits. The maximum number of digits n2 is, for example, the number of digits that can be displayed without interruption in the product display range 121 by using standard display characters. The minimum number of digits n1 is, for example, a number smaller than the maximum number of digits by several digits.

In step 301, if the number of digits of the retrieved product name is within the range of the standard number of digits (n1≤number of digits≤n2), the font data is read from the font file 170 and the size of the standard display character described above is read. Then, the product name is displayed (step 302). FIG. 4A shows a state in which the product name is displayed in the product display range 121 by the standard display characters in this way.

If the number of digits of the product name is smaller than the minimum number of digits n1, the font data is read from the font file 170 and enlarged to the maximum size that can be displayed in the product display range 121 (step 303). Display is performed with the maximum size display character (step 304). FIG. 4B shows a state in which the product name is displayed in the product display range 121 with the enlarged maximum size display character in this way.

If the number of digits of the product name is larger than the maximum number of digits n2, the number of digits of the product name is further compared with the second reference number of digits n3 (step 305). This second reference digit number n3
Is set as a standard when displaying the product name in multiple lines, and when the product name is reduced and displayed on one line, the number of digits that is too small to be displayed is difficult to check. It is set. Note that the number of lines to be divided is usually 2 because the size of the product display range 121 is limited.
Limited to about a row.

In step 305, when the number of digits of the product name is smaller than the second reference number of digits n3, the font data is read from the font file 170, and the standard size is displayed up to the product display range 121 without interruption. The display character is reduced from the displayed character (step 306), and the reduced display character is displayed (step 307).
FIG. 4C shows a state in which the product name is displayed in the product display range 121 with the reduced display characters in this way.

In step 305, if the number of digits of the product name is larger than the second reference number of digits n3, the font data is read from the font file 170 and reduced to a size smaller than the standard display characters in accordance with the product display range 12. (Step 308), and the reduced display characters are divided into a plurality of lines for display (Step 309). FIG. 4D shows a state in which the product name is displayed in the product display range 121 with the reduced display characters divided into two lines.

Although the present invention has been described above with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments. For example, the maximum number of digits and the minimum number of digits were set as the standard number of digits and compared with the number of digits of the searched product name, but only one standard number of digits was set, and the number of digits larger or smaller than the standard number of digits was set. Depending on the case, the enlargement or reduction processing may be performed. Further, in the above-described embodiment, the case where the display is made by the character enlarged from the standard display character and the case where the display is made by the reduced character are shown.
It is also possible to display only the reduced character without performing the enlarged display than the standard display character.

Further, in the above embodiment, the font file 170 stores font data such as a bitmap or a scalable font that can be enlarged or reduced. However, the minimum size character font data to be displayed in the display range is the font file 170. Even if the character font is stored in, and the character font is enlarged to a predetermined size for display, the same display as described above is possible. The character font having the smallest size is stored because the character font can be expanded but not reduced. Also, when the character font is enlarged, the dots become coarse characters, but it seems that there is no practical problem if only the product name is confirmed regardless of the quality of the displayed characters.

[0024]

As described above, according to the POS terminal device of the present invention, the size of the display character is changed according to the number of digits of the product name, so that the product name is displayed intermittently. Even if the product name is long, the operator can accurately confirm the product name. In addition, since it is not necessary to register in the PLU table a name omitted in the number of digits within the display range for a product name whose number of digits exceeds the display range, the labor of creating the PLU table is reduced.
