Further, the touch panel 11 sends the data of characters and numbers displayed at the pressed portion to the CPU 10 by pressing the display surface displaying the data of characters and numbers with a finger or the like.

The operation of the circuit configuration shown in FIG. 2 will be described below with reference to FIG.
This will be described with reference to the flowchart of. A customer who wants to purchase a product makes a payment with a card. The password for this card is "5678" which is a four digit number. Further, the RAM 13 is provided with a counter for the CPU 10 to add “1” each time a password is input from the touch panel 11. This counter is the CPU 10
The CPU is incremented by 4 and becomes 4
10 is a counter for recognizing that the input of the 4-digit password is completed.

First, the customer inserts a card into the card insertion device 14 to make a payment. The card insertion device 14
The password of the inserted card is read and the password is sent to the CPU 10. The CPU 10 stores the card password “5678” in the RAM 13 (S
1). Further, the counter provided in the RAM 13 is cleared to "0" (S2).

Next, the CPU 10 generates data of the numbers 0 to 9 to be displayed on the touch panel 11 (S3), and further generates data on how to arrange the numbers on the touch panel 11. (S4). The data for placing this number is randomly generated. C
The PU 10 sends these data to the touch panel 11 (S5).

The touch panel 11 displays the numerical data sent from the CPU 10 according to how to arrange the numerical data. The display on the touch panel at this time is shown in FIG.

The customer looks at the display on the touch panel 11 shown in FIG. 4A and inputs the password to be entered. Since the password is "5678", the customer first presses "5" displayed on the touch panel 11. The touch panel 11 inputs the data of the pressed numeral "5" and sends it to the CPU 10.

When the CPU 10 receives the data of "5" which is the number pressed from the touch panel 11, the RAM 13
This data is stored in (S6). Then, the CPU 10
Adds "1" to the counter of RAM 13 (S7),
It is compared whether or not the number stored in the counter is "4" or more (S8). If the counter is “4” or more, it means that the password input is completed, but it is currently “1”, and the CPU 10 generates the numerical data 0 to 9 to be displayed on the touch panel 11 again. (S3),
Data on how to arrange these numbers is generated (S4). The data for placing this number is randomly generated. The CPU 10 sends these data to the touch panel 11 (S5).

The touch panel 11 displays the numerical data sent from the CPU 10 according to how to arrange the numerical data. The display on the touch panel at this time is shown in FIG. Since the data for arranging the numbers is randomly generated, it is displayed differently from the arrangement of the character string on the touch panel 11 at the time of the first password input.

The customer looks at the display on the touch panel 11 shown in FIG. 4B and inputs the password to be entered. The password is "5678" and already "5"
Since the input has been made, the customer will press the “6” displayed on the touch panel 11. The touch panel 11 sends the data of the pressed numeral “6” to the CPU 10.

Upon receiving the data "6" from the touch panel 11, the CPU 10 stores this data in the RAM 13 (S6). Next, the CPU 10 causes the RAM 13
"1" is added to the counter (S7), and it is compared whether the number stored in the counter is "4" or more (S7).
8). Since the counter is currently "2" and less than "4",
The CPU 10 displays 0 for displaying again on the touch panel 11.
Data of numbers from 9 to 9 is generated (S3), data of how to arrange these numbers is generated (S4),
These data are sent to the touch panel 11 (S5). The data for arranging the numbers is randomly generated.

The touch panel 11 displays the numerical data sent from the CPU 10 according to how to arrange the numerical data. The display on the touch panel at this time is shown in FIG. Since the data for arranging the numbers is randomly generated, it is displayed differently from the arrangement of the character strings on the touch panel 11 at the time of the second password input.

The customer looks at the display on the touch panel 11 shown in FIG. 4C and inputs the password to be entered. Since the password is “5678” and “5” and “6” have already been input, the customer touch panel 11
It means to press "7" displayed in. The touch panel 11 displays the data of "7" which is the pressed number by the CPU.
Send to 10.

Upon receiving the data "7" from the touch panel 11, the CPU 10 stores this data in the RAM 13 (S6). Next, the CPU 10 causes the RAM 13
"1" is added to the counter (S7), and it is compared whether the number stored in the counter is "4" or more (S7).
8). Since the counter is currently "3" and less than "4",
The CPU 10 generates data of numbers 0 to 9 to be displayed on the touch panel 11 again (S3), and generates data of how to arrange these numbers (S3).
4) Send these data to the touch panel 11 (S
5). The data for arranging the numbers is randomly generated.

The touch panel 11 displays the numerical data sent from the CPU 10 according to how to arrange the numerical data. The display on the touch panel at this time is shown in FIG. Since the data for arranging the numbers is randomly generated, it is displayed differently from the arrangement of the character string on the touch panel 11 at the time of the third password input.

The customer looks at the display on the touch panel 11 shown in FIG. 2D and inputs the password to be entered. Since the password is "5678" and "5", "6" and "7" have already been input, the customer presses "8" displayed on the touch panel 11. The touch panel 11 sends the pressed data “8” to the CPU 10.

Upon receiving the data "8" from the touch panel 11, the CPU 10 stores this data in the RAM 13 (S6). Next, the CPU 10 causes the RAM 13
"1" is added to the counter (S7), and it is compared whether the number stored in the counter is "4" or more (S7).
8). Since the counter is currently “4” and is 4 or more, the CPU 10 inputs the password of the card stored in the RAM 13 and the touch panel 11 to the RAM 1
The password stored in 3 is compared (S9).

If the password of the card stored in the RAM 13 and the password input from the touch panel 11 match, the settlement terminal device makes a settlement. If they do not match, enter the password again (S2),
Make sure to give a warning.

As described above, every time one character of the password is input, the numeral arrangement for password input is changed. This makes it possible to prevent the password from being known from the movement of the hand that inputs the password.

By the way, in the above description, the password is only a numeral, but of course, an alphabet or a symbol may be used. Also, the number portion of the touch panel 11 pressed by the customer is lit for a certain period of time. By doing so, the customer can know that the touch panel 11 has been pressed, and can prevent the same number from being input again. For example, "1" displayed on the touch panel 11
When is pressed, the touch panel 11 causes the pressed part of the numeral "1" to be lit for a certain period of time. Then, the customer knows that one character of the password has been input as "1", and can prevent the user from pressing the "1" again in anxiety. Of course, each time the password is entered, the displayed number array is changed.

As another method, the touch panel 11
Causes a signal to be output to the CPU 10 when the display is pressed with a finger. For example, a speaker is provided in the output port of the CPU 10. The CPU 10 has a touch panel 11
When a signal from is input, a signal for outputting sound is output to the speaker. Even in this case, it is possible to prevent the same number from being input again. Of course, each time the password is entered, the displayed number array is changed.

Further, although the touch panel 11 inputs the password by being pressed with a finger, the touch panel 11 may be provided with a lever and the password may be input by moving the lever. Fig. 5 shows a diagram of a touch panel with a lever attached, (a) is a plan view,
(B) is a front view and (c) is a perspective view.

The touch panel 20 shown in the figure displays nine numbers, and a lever 21 is arranged between the numbers "2" and "5". The lever 21 moves up and down, left and right, and diagonally with a portion connected to the touch panel 20 as a fulcrum. Also, the lever 21 is used for the touch panel 20 except when it is tilted with a finger or the like.
Stand perpendicular to the display surface of.

The touch panel 20 inputs the numerical data in the tilted direction by tilting the lever 21 in the direction of the displayed numeral. For example, if the lever 21 is tilted in the upper left direction, "1" is input, if it is tilted in the upper direction, "2" is input, and if it is tilted in the upper right direction, "3" is input. In addition, "4" is input as the data is tilted to the left, "5" is input as the data is pressed vertically downward, and "6" is input as it is tilted to the right as data. In addition, "7" is input as the data is tilted to the lower left, "8" is input as the data is tilted downward, and "9" is input as it is tilted to the lower right. Also, the lever 21 is
For example, it may be made of transparent plastic and attached directly above the numeral "5" on the touch panel 20 shown in FIG. At this time also, the same operation as described above is performed to input data. Of course, each time the password is entered, the displayed number array is changed.
Thus, even if the lever 21 is tilted in the direction of the password number to be input, the password can be input without being known by a third party.

[0039]

As described above, in the terminal device of the present invention, the arrangement of the character string for entering the password is changed every time one character of the password is entered, so that the password is entered. The movement of the hand can prevent the password from being known to a third party.
