Even if the size is written on one side of the LCD screen or in a small (or large) size, the digital signature is utilized by making full use of the space allocated to the signature area on the sales slip through the expansion / reduction process of the electronic signature according to the present invention. Can print.

Figure 4 is a view showing an example in which the electronic signature input to the LCD (or touch panel) capable of customer electronic signature of the card terminal device 100 according to the present invention is printed on the sales slip.

As shown in Figure 4, the signature input unit of the card terminal device 100 according to the present invention is provided with an LCD (or touch panel) capable of customer electronic signature, the customer using a pen or the like LCD (or touch panel) When the liquid crystal display (90) is pressed, the pen detects the pressure of pressing the liquid crystal display (90) and an electronic signature is generated by drawing an image corresponding thereto.

The electronic signature generated as described above is printed on the signature column 62 of the sales slip 60, and the LCD screen 90 and the signature column 62 of the LCD (or touch panel) are substantially rectangular. The liquid crystal display 90 of the LCD (or touch panel) is manufactured in a rather large size (for example, 9 cm wide and 6 cm long) so that a customer can conveniently enter their signature using a pen (or puck). do. On the other hand, since the signature column is formed in a limited area on the sales slip 60, a much smaller size (for example, 2.3 cm and 1.2 cm) than the LCD screen 90 of the LCD (or touch panel). Is formed.

And 128 pixels wide and 64 pixels long on the LCD screen 90, and each pixel is assigned to a corresponding position in the signature column 62. FIG. Therefore, the electronic signature described on the LCD screen 90 of the LCD (or touch panel) may be printed on the signature line 62 by reducing the width W and the length L in the same ratio.

In the above case, when the customer writes his / her signature over the entire area of the LCD screen 90 of the LCD (or touch panel) interworking with the signature input unit, the sales slip 60 corresponding to the LCD screen 90 is displayed. The digital signature is printed on the entirety of the signature column 62).

On the other hand, as shown in Figure 4, if the customer enters his signature in a small form on the corner of the LCD screen 90 of the LCD (or touch panel), also sales slip 60 The electronic signature is printed at one corner of the signature column 62 on the upper part of the signature. In this case, the signature is printed on the signature column 62 in a very small size. There is a problem that it is difficult to judge the authenticity of the signature.

5 is a view showing the principle of normalizing the customer electronic signature through the card terminal device 100 according to the present invention.

In the present invention, regardless of the size or position of the electronic signature input to the liquid crystal display 70 of the LCD (or touch panel) capable of customer electronic signature interoperating with the signature input unit using a signature processing unit, By extending the vertical length to a predetermined magnification and normalizing it, the electronic signature can be printed by making the most of the space in the signature column 62 of the sales slip 60.

First, referring to FIG. 5A, when the horizontal length of the liquid crystal screen 70 of the LCD (or touch panel) capable of customer electronic signature interworking with the signature input unit is W and the vertical length is L, the LCD screen It can be seen that the electronic signature is described at the lower right of 70. In the present invention, in order to calculate the size of the electronic signature, it is assumed that the rectangle 71 of the minimum size that can include all the electronic signature, the horizontal length (w) and the vertical length (ㅣ) of the rectangle (71) Calculate the size of the digital signature using.

In FIG. 5A, it can be seen that the horizontal length w of the electronic signature is W / 3 and the vertical length l is L / 2. In this case, the magnification W / w of the horizontal length W of the LCD screen 70 with respect to the horizontal length w of the digital signature is three. In addition, the magnification L / l of the vertical length L of the LCD screen 70 with respect to the vertical length l of the digital signature is 2.

In this case, the present invention is based on the smaller magnification of the horizontal and vertical lengths of the LCD screen relative to the horizontal and vertical lengths of the electronic signature, and expands the electronic signature by the small magnification.

In FIG. 5A, it can be seen that a smaller magnification of the horizontal and vertical lengths of the LCD screen 70 with respect to the horizontal and vertical lengths of the digital signature is the magnification with respect to the horizontal length (W / w). Therefore, the horizontal and vertical lengths of the digital signature are each enlarged by a magnification (W / w) of the horizontal length, that is, twice the size. Since the electronic signature is enlarged based on the small magnification, the electronic signature after the enlargement can be prevented from being distorted or leaving the space of the liquid crystal display 70.

In this case, as shown in FIG. 5B, the electronic signature may be enlarged in a diagonal direction with respect to one edge 72 of the LCD screen 70 of the LCD (or touch panel).

Then, as shown in FIG. 5C, an electronic signature of an enlarged image is formed on the right side of the LCD screen 70, and the enlarged electronic signature is also a space on the right side of the signature column 62 on the sales slip 60. Can be printed utilizing the maximum.

6 is a view showing the principle of normalizing the customer electronic signature through the card terminal device 100 according to an embodiment of the present invention.

In FIG. 6, the principle of enlarging the electronic signature 71 input to the LCD screen 70 of the LCD (or touch panel) capable of customer electronic signature interworking with the signature input unit is the same as described with reference to FIG. 5.

However, in another embodiment of the present invention, as shown in FIG. 6A, the electronic signature 71 described at one corner of the LCD screen 71 of the LCD (or touch panel) is displayed. It can be enlarged in the up, down, left and right directions with respect to the center 73 of the liquid crystal display 70 of the panel).

Then, as illustrated in FIG. 6C, an electronic signature of an enlarged image is formed at the center of the LCD screen 70 of the LCD (or touch panel), and the enlarged electronic signature is also a signature column on the sales slip 60. It can be enlarged and printed at the center of 62.

According to the present invention, a keypad (or keyboard) equipped with a backlight function is compensated for erasing the printing of numbers, letters, and other function keys of an existing keypad (or keyboard), and a card interface equipped with a backlight function is provided. The advantage is that cards (eg credit cards, etc.) can be easily read in the dark.
