Next, the electrical configuration of the information device 1 will be described with reference to FIG.

The information device 1 of this embodiment operates according to a command from the CPU 13 connected to the host computer 31. The CPU 13 functions as the key arrangement control means of the present invention, and includes the card reader 2, the CRT display device 3, the touch panel 4, and the bill collecting device (bilberry) 5 described above.
A coin sorting / collecting device (coin mech) 6, a timer 51 for marking the time and date, a journal printer 12 for printing receipts, a voicing device 16 for audibly explaining the operating method, and a CPU 13. Hard disk 17 which stores the operation program for issuing the product by controlling the information device 1 to operate according to a predetermined process.
And an RA loaded with an operation program for operating the laser printer 11 and the information device 1 according to a predetermined process.
An M19 and a VRAM 20 that is temporarily stored to display image data are connected. The program for operating the information device 1 is stored in the RAM from the hard disk memory 17
19 and is operated based on the program.
The hard disk memory 17 also stores 60 types of key layout patterns.

Next, the operation of the information apparatus 1 having the above configuration will be described with reference to the flow charts shown in FIGS.
Further, description will be made with reference to the screen displays of FIGS. 3 and 4.

The information device 1 is usually operated by the CPU 13
A screen display for prompting card insertion as shown in FIG. 3 is shown on the CRT display device 3.

First, the CPU 13 determines whether or not an ID card has been inserted (step 100. Hereinafter, the step will be simply referred to as S). The CPU 13 constantly monitors whether the ID card is inserted in the card reader 2,
When the insertion of the ID card by the user is detected (S10
0: YES), and instructs the card reader 2 to read data (S110).

The card reader 2 reads the data recorded on the ID card and transfers the data to the CPU 13. Then, the CPU 13 confirms whether the inserted ID card is a card for the information device (S12).
0).

If this card is not the card for the information device 1 (S120: NO), the I card is inserted from the card insertion slot 2a.
Eject the D card (S130) and CR to that effect.
It is displayed on the T display device 3 (S140).

On the other hand, if the inserted card is the card for the information device 1 (S120: YES), the personal identification number guidance process is performed (S150).

Here, the personal identification number guidance processing will be described with reference to FIG.

The CPU 13 reads the personal identification number key arrangement program stored in the hard disk 17 (S
501). In this case, as the content of the program stored in the hard disk 17, for example, as shown in FIG.
When 13 detects the time when the user enters the password input operation, the time is read from the timer 51. Then, based on the number of seconds (for example, 10 seconds), the array pattern 10 (10d) corresponding to the number of seconds is read out of the array pattern of the key array storage area, and is displayed on the CRT display device 3, for example, in FIG. 4a. It is conceivable to display the arrangement of keys as shown. When another user operates next, the CPU 13 reads the second when the personal identification number is input from the timer 51 (for example, 30 seconds), and is stored in the key layout storage area of the hard disk 17 based on the second. It is conceivable that the arrangement pattern 30 (10e) corresponding to that second is read out from the arrangement pattern and the arrangement as shown in FIG. 4b is displayed on the CRT display device 3, for example. Then, it is loaded into the RAM 19 (S5
02). Further, the design that is the base of the CRT display screen is loaded into the VRAM 20 (S503). And C
Based on the program loaded into the RAM 19, the PU 13 causes the CRT display device 3 to display the personal identification number key array (S504).

In this case, when a user uses the information terminal 1, it is assumed that the keys are arranged as shown in FIG. 4a, for example. Then, after the use of the user, when the next user uses the information terminal 1, the CPU 13 changes the key arrangement as shown in FIG. 4B, for example, based on the program stored in the hard disk. . As a result, the key arrangement of the personal identification number changes randomly each time the user uses it, so when a certain user uses the information device 1, a third party secretly watches the movement of the user's hand. It is not possible to know the personal identification number of the user just by looking at it.

Then, the process returns to the main routine.

The CPU 13 determines whether or not the user has pressed the touch panel 4 to input the personal identification number (S160), and if the personal identification number has been input (S160: YES),
CPU13 is the user's ID recorded on the ID card
The identification code and the entered personal identification number are transmitted to the host computer 31. Host computer 31 is CPU1
The user ID identification code transmitted from No. 3 and the personal identification number are collated (S170), and if the personal identification number is not correct with respect to the user ID identification code (S180: NO), the fact is transmitted to the CPU 13 and the personal identification number is again provided. Guidance process (S
150) is performed. That is, the screen display prompting the user to input the personal identification number is displayed on the CRT display device 3, and the utterance device 16 is also uttered.

If the personal identification number is correct (S180:
If YES, the CPU 13 ejects the ID card from the card insertion slot 2a and performs selection guidance processing (S19).
0). Although this is not shown, the menu selection screen is CR
A message is displayed on the T display device 3, and a signal is also sent to the voicing device 16 to utter, for example, "Please select the necessary product."

Then, the CPU determines whether or not the selection input of the menu is made by the user (S200),
When the selection is input, the charge display is displayed (S21).
0). This is a screen (not shown) that prompts you to pay the fee.
Along with displaying on the RT display device 3, a signal is also sent to the utterance device 16 to utter, for example, "please charge."

When the CPU 13 confirms the prescribed fee collection (S220: YES), it shifts to the product issuing process (S).
230). That is, the CPU 13 causes a predetermined floppy disk to be ejected from the floppy disk ejection opening 9, and when the user inserts it into the floppy disk insertion opening 9 of any of 7a, 7b and 7c, the host computer 3
The program of the product selected by the user, which is downloaded from No. 1 and recorded in the hard disk 17, is written. After writing, the process moves to the instruction issuing process (S2
40). That is, the CPU 13 sends to the laser printer 11 the data necessary for creating a manual corresponding to the product to be printed. Then, the printed instruction sheet is ejected from the instruction sheet ejection port 10.

As described above, according to the information device 1 of this embodiment, the arrangement of the personal identification number can be changed at random, so that when a certain user inputs the personal identification number, a third person can change the personal identification number. It is impossible to guess the personal identification number by looking at the movement of the user's hand. Therefore, the user can calmly use the information device 1 without worrying about the eyes of others. .

The present invention is not limited to the above embodiments, but can be applied to, for example, an automatic certificate issuing machine, an automatic teller machine such as a bank, and the like. Further, FIG.
As shown in a and b, changes in the arrangement of the PIN code keys may be rotated. In addition, as shown in FIG.
Color may be assigned to each key to improve usability.

[0032]

As is apparent from the above description,
According to the information device of claim 1, the key arrangement for the personal identification number can be changed for each use of the user.
When a user is inputting a personal identification number, it is impossible for a third party to guess the personal identification number by looking at the movement of the user's hand, so the user cares about the eyes of others. Without having to worry, you can rest assuredly use the information device. Further, according to the information device of the second aspect, since each of the keys has a unique color, it becomes easier for the user to operate when inputting the personal identification number.
