BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a device for inputting a personal identification number for preventing snooping according to the present invention will be described with reference to the accompanying drawings. In FIG. 1, a secret number input device for preventing the snooping indicated by reference numeral 4 is a display member 3 (for example, a liquid crystal panel) and a translucent member 1.
A gap is provided between (for example, a touch panel), and the space between the numbers on the display member 3 is partitioned by the obstacle 2 so that only the parties can see the numbers. When a party inputs a recitation number with the input device, for example, the number 4 on the display member 3 can be seen from the viewpoint A, which is the position of the party in FIG. 2, but is obstructed from the viewpoints B and C, which are the positions of the third party. Since the number 4 cannot be seen because it is blocked by the object 2, it is possible to prevent a third party from snooping. In FIG. 1, each number is separated by an obstacle 2 and is located at the bottom of a square booth. The shape of the booth is not limited to a square, and may be a circle, an ellipse, a rectangle, or a polygon.
Moreover, even if each of the obstacles 2 is not independent,
It may be an integral body as shown in the drawing.

In FIG. 3, the obstacle 2 in FIG. 1 is not provided,
An opaque member 5 having a window 7 through which the number of the display member 3 is visible is provided above or below the translucent member 1 to prevent a third party from snooping. The opaque member 5 includes a member that is always opaque and a member that becomes opaque when electricity is applied or becomes opaque when electricity is cut off (for example, instantaneous light control glass). For example, the number 4 on the display member 3 can be seen from the viewpoint A, which is the position of the parties in FIG. 3, but the numbers cannot be seen from the viewpoints B and C, which are the positions of the third parties, because they are blocked by the opaque member 5. , It is possible to prevent a third party from stealing. FIG. 4 shows the opaque member 5 of FIG.
Indicates. The shape of the window 7 in FIG. 4 may be a circle, an ellipse, a square, a rectangle, or a polygon.

In FIG. 5, instead of providing the opaque member 5 in FIG. 3, the transparent member 1 itself is viewed from the viewpoint A, and the display member 3 is provided.
Is made opaque except for the minimum part where the numbers are visible, or the translucent member 1 itself is covered with an opaque coating except for the minimum part where the numbers of the display member 3 are visible from the viewpoint A, or
A transparent member 1 (for example, instantaneous light control glass) that becomes opaque when electricity is applied or becomes opaque when electricity is turned off is used except for the minimum visible part of the display member 3. In the case of an automatic teller machine (ATM) or an automatic teller machine, when the shaded area in FIG. 16 (personal identification number eavesdropping prevention device) becomes opaque when electricity is applied, or when electricity is turned off It becomes opaque. That is, since the screen of the automatic cash depositing / dispensing machine (ATM) or the display member (for example, liquid crystal panel) of the automatic cash dispensing machine displays various screens, a device other than a PIN-sniffing prevention device for a translucent member (for example, a touch panel) is displayed. Is always transparent, and only the shaded area in FIG. 16 is opaque when the personal identification number anti-thief device is functioning. From the viewpoint A, which is the position of the person in FIG. 5, for example, the numeral 4 on the display member 3 can be seen, but from the viewpoints B and C, which are the positions of the third party, it is blocked by the opaque portion of the translucent member 1. Since the numeral 4 on the display member 3 cannot be seen, it is possible to prevent a third party from snooping. FIG. 6 shows the translucent member 1 in FIG. 5, and the shaded portion is opaque. Figure 6
The shape of the transparent portion 13 in which the number is visible may be any of a circle, an ellipse, a square, a rectangle, and a polygon.

In FIG. 7, each convex or concave lens 6 is attached to the top or bottom of the transparent member 1, or a transparent member integrated with each convex or concave lens is used. The number on the display member 3 is made small for a convex lens and made large for a concave lens in order to prevent a third party from snooping. When a convex lens is used from the viewpoint A, which is the position of the person concerned, the small number 4 on the display member 3 is enlarged by the effect of the convex lens to be seen by the person in an appropriate size, and when a concave lens is used, Due to the effect, the enlarged number 4 on the display member 3 is reduced and can be seen by the parties with an appropriate size, and the light is refracted from the viewpoints B and C, which are the positions of the third person, so that the number 4 cannot be seen. It is possible to prevent a third party from stealing. The transparent member 1 and the convex or concave lens may be made of glass or plastic. The shape of the lens 6 in FIG. 7 may be a circle, an ellipse, a square, a rectangle, or a polygon.

8A and 8B are automatic cash deposit / withdrawal machines (AT
M), or an automatic cash deposit / withdrawal machine (AT) when an anti-theft device for inputting a personal identification number for the automatic cash dispenser operates.
M) or the entire display screen of the automatic cash dispenser. The hatched portion is an anti-snooping device, and the shaded portion is opaque when the anti-stealing device is functioning. FIG. 9 is a sectional view taken along line X′-X ′ of FIG. Automatic cash deposit / withdrawal machine (AT
M), or a secret-code input device for preventing wiretap for an automatic cash dispenser, a gap is provided between the display member 3 (for example, a liquid crystal panel) and the translucent member 1 (for example, a touch panel). A member 11 having a window 12 through which the number of the display member 3 can be seen from the viewpoint A is provided above or below the view point 1. This member 1
1 is a member that becomes opaque when electricity is applied or becomes opaque when electricity is turned off (eg, instantaneous light control glass)
When the party inputs the recitation number with the input device, for example, the number 4 on the display member can be seen from the viewpoint A which is the position of the party in FIG. 9, but the viewpoint B which is the position of the third party.
Since C and C are blocked by a member that becomes opaque when electricity is applied or a member that becomes opaque when electricity is cut off (for example, instantaneous light control glass) 11, the number 4 cannot be seen, so It is possible to prevent spying and only the parties can see the numbers on the display members. Automatic cash dispenser (ATM),
Alternatively, the member 11 provided above or below the translucent member (for example, touch panel) of the automatic cash dispenser needs to be opaque through electricity or cut off electricity only when the screen displaying the personal identification number. There is. FIG. 10 shows the member 11 in FIG. The shape of the window 12 in FIG. 10 is a circle, an ellipse,
It may be square, rectangular or polygonal.

FIG. 11 shows the member 15 of claim 3. The member 15 does not open the window like the member 11, and the portion 14 (circled portion) corresponding to the window is always transparent when electricity is passed or cut off, and the portion not corresponding to the window ( The shaded portion) is made of a member that becomes opaque when electricity is applied or becomes opaque when electricity is turned off (for example, instantaneous light control glass). Automatic cash dispenser (ATM),
Alternatively, the member 15 provided above or below the translucent member 1 (for example, a touch panel) of the automatic cash dispenser can conduct electricity only when the screen displaying the personal identification number is removed, except for the circled portion 14 of the member 15. You need to make it opaque or turn off the electricity to make it opaque. The shape of the circled portion 14 of the member 15 may be a circle, an ellipse, a square, a rectangle, or a polygon. When the party inputs the recitation number with the input device, for example, the numeral 4 on the display member 3 can be seen from the viewpoint A, which is the position of the party in FIG. 12, but the electricity is visible from the viewpoints B and C, which are the positions of the third party. The number 4 cannot be seen because it is blocked by the member 15 that becomes opaque when passing through or the member 15 that becomes opaque when electricity is cut off, so it is possible to prevent a third party from snooping, and only the parties can view it. You can see the numbers on the member 3.

For example, when a liquid crystal panel is used as a display member, a pattern of several kinds of numbers is prepared as shown in FIGS. 13 and 14, and the software is changed by a changeover switch to change the liquid crystal panel (display member). You may change the arrangement of the numbers shown in (above). For example, there are 3 in pattern A, 0 in pattern B, 4 in pattern C, and 1 in pattern D at each 8 position in FIG. Further, for example, it is also possible to arrange the numbers in a horizontal row like the pattern E or the pattern F in FIG. 14 or to arrange like the pattern G or the pattern H. With the conventional method, the numbers are always in a fixed position, but in the present invention, the software can be changed with the changeover switch to change the arrangement of the numbers, so a third party can imagine the numbers at the finger positions of the parties. I can't do it, and I can't sniff my PIN. FIG. 13 is an example of a numerical array pattern of a personal identification number input device for a debit card or a credit card. FIG. 14 is an example of an array pattern of numbers of an automatic teller machine (ATM) or a personal identification number input device of the automatic teller machine.

A method of partitioning the numbers on the display member with an obstacle 2, a method of providing a member 5 in which a window through which the numbers of the display member are visible are provided, and a method of making the portions other than the numbers of the translucent member visible are opaque. , A method of attaching a lens to a translucent member, a method of using a member 11 which becomes opaque when a member with a window opened conducts electricity or when electricity is cut off, and a portion corresponding to the window without opening the window The method of providing the member 15 that is always transparent is a method for preventing direct snooping by a third party, and the method of changing the arrangement of the numbers on the display member is a method for preventing indirect snooping. Is. These methods may be used in combination to further improve the anti-theft effect. For example, there is a method in which the lens 6 is attached to a portion of the translucent member where the numbers can be seen, and the number arrangement of the display member is further changed.
