Description

The present invention relates to a PIN code input device that has been widely adopted in automatic teller machines (ATMs) and the like. More specifically, the present invention relates to a personal identification code input device that inputs a personal identification code when paying out or depositing cash or when paying with a credit card.
Since many of these types of input devices use numbers from 0 to 9, they are generally often referred to as personal identification number input devices. However, since characters such as alphabets and hiragana can be used in the same manner, in this specification, those including numbers, alphabets, hiragana and the like are used as codes, and an input device used for password is referred to as a password input device. .

Some devices such as ATMs installed in banks and convenience stores have a side wall provided to hide their hands so that they are not peeped by people around them when inputting a password. However, even if a side wall is provided, there is a risk of peeping from behind, and there are many crimes that take place after a special instrument is attached to the ATM and the password is stolen.
For this reason, many proposals relating to techniques for preventing peeping have been made. For example, in Patent Document 1, a light-shielding filter portion is arranged at the upper front portion of a code input device, an opening enough to insert a finger is formed at the lower front portion, and only an opening for inserting a finger when an operator inputs a code. The remaining other parts are enclosed so that they can be seen more securely.

However, the technique according to Patent Document 1 has a protruding structure because a cover structure that covers the upper surface of the code input device is additionally provided. Furthermore, since the code | symbol displayed on the display is seen through the cover structure, it will become difficult to see.
In recent years, the code input device as described above has been adopted for various devices and facilities. In the case of ATM, the cover structure can be adopted. Some devices and equipment cannot adopt a cover structure or make the cover structure inappropriate.
For example, the code input device is used in coin lockers, vending machines, and the like, and is also used for unlocking electronic locks installed at the entrance doors of houses. In these cases, the code input device is often installed on the front door that stands vertically from the ground. Further, in these cases, unlike an ATM installed indoors, the input portion of the code input device is exposed to the outside world, and it is easy to be seen by an unspecified person.
However, on the other hand, it is not easy to add a cover structure to the code input device in a coin locker, a vending machine, or the like. In the case of vending machines installed on the road, there is a possibility that the protruding cover structure may hit a passerby, and furthermore, the road traffic law prohibits protrusion to the road, so it is necessary to consider violations of laws and regulations .

  Accordingly, an object of the present invention is to provide a password input device that can prevent a password from being looked into without providing an additional structure such as a cover structure that covers the upper portion.

  The above object is a personal identification code input device that is applied to an electric device and permits the processing of the electric device requested by an operator only when a code that matches a preset personal identification code is input, A display input unit formed as a region for displaying a code and inputting a personal identification code by an operator, and at least one finger of the operator is placed on the periphery of the display input unit A personal identification code input device, wherein the personal identification code is input to the display input unit with a finger other than a finger placed on the finger placement unit. Achieved.

  The finger placement unit is designed to place a plurality of fingers, and when the operator places a plurality of fingers on the finger placement unit, the operator's palm is positioned above the display input unit. Thus, it is preferable that the positions of the finger placement unit and the display input unit are set.

  The finger placement unit may include a sensor that detects the presence or absence of a finger, and may include a control unit that controls display of the display input unit and input of the password based on the output of the sensor. .

  It is preferable that the control unit displays the input code on the display input unit only when the sensor detects a finger.

  The finger placement unit is designed to place a plurality of fingers and includes sensors for detecting the presence / absence of fingers, and controls the display of the display input unit and the code based on the output of the sensor. A control unit for controlling the input of the sensor, and the control unit displays the code in a region corresponding to each sensor, and the display is performed when all fingers are placed on the finger placement unit. All the input codes may be displayed on the input unit.

  Moreover, it is more preferable that the control unit is set so as to change the arrangement of the codes displayed on the display input unit.

And it is preferable that the said finger placement part is arrange | positioned in the periphery of the said display input part for right-handed use and left-handed use, respectively.
Moreover, the said finger rest part may be rotatably arrange | positioned at the outer peripheral part of the said display input part, and may be formed so that it can respond to right-handedness and left-handedness.

  Further, the finger placement unit may be a finger placement mark by printing, and a configuration may be provided in which it is recommended to input after placing a finger on the finger placement mark beside the finger placement mark.

  ADVANTAGE OF THE INVENTION According to this invention, the code input device which can prevent the peeping of a code reliably can be provided, without providing additional structures, such as a cover structure which covers an upper part.

It is the block block diagram shown in order to demonstrate one suitable form of the PIN code input device which concerns on this invention. It is a front view of a PIN code input device. (A)-(c) is the schematic diagram which showed in order the mode at the time of inputting a code | symbol with the PIN code input device of FIG. It is the figure which showed the example of improvement of a PIN code input device. It is the figure which showed the other example of improvement of the PIN code input device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a preferred embodiment of a code input device according to the present invention. The personal identification code input device 1 displays a personal identification code and is provided so as to place a display input unit 2 formed as an area for inputting the personal identification code and at least one finger of the operator. And a finger placement unit 3. The display input unit 2 is not particularly limited as long as it is a component that can perform an input operation when the operator touches the code at the same time when the code is displayed. For example, a transparent pointing device (matrix switch type, resistive film type, surface acoustic wave type, infrared type, static type, etc.) on a display screen formed of liquid crystal or the like, as in the case of a touch panel device adopted in a conventional ATM. It is possible to suitably employ a configuration in which an electrical capacity method is provided, and when an operator's finger touches the screen, this is electrically detected.
In the display input unit 2 of the personal identification code input device 1, the palm of the person to be operated is located at the upper part, and the area is large enough to cover the display unit with the palm (planar size). ) Is preferred.
The finger placement unit 3 is arranged around the display input unit 2 and is designed so that the operator can input the password to the display input unit 2 with a finger other than the finger placed on the finger placement unit 3. It is. A preferable form of the display input unit 2 and finger placement unit 3 and a state of code input will be described in detail later.

  The PIN code input device 1 of the present invention is effectively applied as a device that is applied to the existing electric device 100 and contributes to the determination of whether or not to permit the processing of the electric device 100 requested by the operator. The electric device 100 to which the present code input device 1 is applied may include various devices that are allowed to process after confirming the code. For example, ATMs installed in the banks and convenience stores mentioned above, devices that send passwords when using credit cards at department stores and restaurants, coin lockers, vending machines, house doors and garages, etc. An electronic unlocking device or the like can be assumed as the electric device 100.

  FIG. 1 shows a preferred block configuration of the configuration related to the code input device 1. The display input unit 2 and the finger placement unit 3 are controlled by the control unit 4 to control the display of the display input unit and input the code. It is controlled. For example, the finger placement unit 3 includes a sensor 3a that detects the presence or absence of a finger, and the control unit 4 controls the display input unit 2 based on the output of the sensor 3a.

For example, the control unit 4 may display the input code on the display input unit 2 only when the sensor 3a detects a finger. If comprised in this way, it can be set as the apparatus corresponding to an energy saving which displays the display input part 2 only when needed. It is more preferable that the control unit 4 changes the arrangement of the codes displayed on the display input unit 2. In this way, since the position of the sign changes each time an input operation is performed, it is possible to cope with an illegal act of guessing the sign at the finger movement position.
In addition, the said control part 4 can be comprised as a controller comprised centering on CPU, and the memory 5 connects. The memory 5 stores a program for driving the display input unit 2 and the finger placement unit 3, data relating to codes displayed on the display input unit 2, and the like.
The password input device 1 in FIG. 1 is connected to an external electric device 100 via an interface 101. The processing of the electric device 100 requested by the operator is permitted only when the code that matches the password set in advance by the password input device 1 is input. In addition, about the control part 4 and the memory 5 of FIG. 1, the structure which implement | achieves these by the microcomputer etc. by the side of the electric apparatus 100 is also employable.

Furthermore, with reference to other drawings, the code input device 1 of the present invention will be described more specifically. The specific example described here is a case where a finger placement unit set to place a plurality of fingers is employed. In addition, the same code | symbol is used about the same component as FIG.
FIG. 2 is a front view of the code input device 1. A central circular area is the display input unit 2, and a finger placement unit 3 is provided along a peripheral portion on the upper right side of the display input unit 2. The finger placement unit 3 is provided with three (plural) finger placement marks 31, 32, 33, and a sensor 3 a (not shown in FIG. 2, see FIG. 1) for detecting a finger is provided for each mark. It is.
Then, as shown in Fig. 2, near the display input unit 2 (here, at the top), "Place your finger on all of the marks. If all the numbers appear, enter your PIN code." It is preferable to clearly indicate that input is not possible unless a finger is placed on the finger placement unit 3.
Although FIG. 2 shows a case where an explanatory text is presented outside the display input unit 2, it is needless to say that the explanatory text may be presented using the display function of the display input unit 2.

FIGS. 3A and 3B are schematic diagrams sequentially illustrating a state when a code is input by the personal identification code input device 1 shown in FIG. 2 from (a) to (c). Although not shown in FIG. 3, the display input unit 2 and the finger placement unit 3 are controlled as a whole by the control unit 4 shown in FIG.
First, the control unit 4 displays an operation guidance message such as “Place your finger” in the display input unit 2.
FIG. 3A shows a state where the operator places the first finger of the right hand on the first mark 31 among the three of the finger placement units 3. At this time, the control unit 4 displays a motion guidance message so as to place another finger, indicating a code (here, 1, 2, 3) corresponding to the first mark 31.
FIG. 3B shows a state when the operator places the second finger of the right hand on the second mark 32. Also at this time, the control unit 4 displays codes (1 to 6 in this case) corresponding to the first mark 31 and the second mark 32, and further displays an operation guidance message so as to place another finger.

FIG. 3C shows a state when the operator places the third finger of the right hand on the third mark 33. At this time, all of the passwords (0 to 9) are displayed for the first time, thereby enabling an input operation.
By placing the finger on each of the three marks 31 to 33 set on the finger placement unit 3 by the operation by the operator shown in FIGS. 3A to 3C, the palm of the operator is displayed on the display input unit 2. Since the sign is input in this state, the peeping can be surely suppressed without providing an additional structure such as a peeping prevention wall.
Note that FIG. 3C shows that the reference numerals on the display input unit 2 are visible for the purpose of this description. However, by adjusting the arrangement positions and mark intervals of the marks 31 to 33 appropriately, It is preferable that the palm is positioned above the display input unit 2 so that the code is difficult to see even when viewed from the periphery.

In the case of an electric device (for example, ATM) to which the code input device 1 of the present invention described above is applied, the code is input for processing of the electric device requested by the operator (for example, withdrawal of cash). When doing, you can operate while reliably preventing peeping from the outside.
In particular, as in the case illustrated in FIG. 3, by making all three (plural) fingers not be placed on the finger placement mark, it is impossible to input, so that the upper part of the display input unit 2 is widened with a palm. While entering the cover, it is possible to prevent peeping more reliably by inputting.
As described above, by changing the arrangement of the codes displayed on the display input unit 2 every time or periodically, it is possible to cope with a case where there is a fraud attempt to predict the code selected according to the position of the finger. .
By the way, in the code input operation in the conventional apparatus, when the operator performs an input operation, the operator does not call attention to peeping. Therefore, in the case of an unsuspecting user, the code code is viewed from behind. There was a fear. However, when the code input device 1 of the present invention is employed, it is required to place a finger on the finger placement unit 3. Such an operation request may also indirectly alert the operator. Therefore, a secondary effect that the operator pays more attention to the surroundings than before can be expected.

Furthermore, referring to another figure, a more preferable code input device is proposed. The example shown in FIG. 2 and FIG. 3 is a preferable form for inputting with the right hand, and it is slightly inconvenient for a left-handed user to operate it as it is.
FIG. 4 shows a structure in which a ring-shaped member 21 is rotatably provided on the outer peripheral portion of the display input unit 2 and the finger placement unit 3 is supported by the ring-shaped member 21. FIG. 4 shows a state where what is on the right side for right-handed use is rotated to the left side and used for left-handed use.
FIG. 5 shows a case in which the finger placement unit 3 is arranged on the left and right sides of the display input unit 2 as a right-handed 3R and a left-handed 3L.

  As illustrated in FIGS. 4 and 5, if the finger placement unit 3 is formed, the above-described series of operations can be smoothly performed in correspondence with a left / right operator.

  As described above, according to the code input device of the present invention, input can be performed while reliably preventing an important code from being looked into. The PIN code input device of the present invention uses the operator's own hand as a barrier, and does not require a disturbing structure that protrudes as before, so there is no distinction between equipment and facilities installed indoors and outdoors. It can be employed in various electrical devices.

In the above embodiment, an example is shown in which three marks are provided so that the palm of the operator is positioned above the display input unit when a finger is placed on the finger placement unit 3. There is no. Even if only one mark is placed and only one finger is placed, it is possible to prevent peeping as compared with the conventional case because it has an effect of covering the display input part with a hand.
The code input device of the embodiment shown in FIGS. 2 to 5 has a display input unit 2 that is compactly formed in a palm size as an example, and can be applied to various electric devices. However, it is possible to improve the existing apparatus to realize the present invention. For example, a general ATM employs a touch panel device (display input unit) of the same size as the A4 paper size, and since it is input on this screen, it is easy to peep from the periphery. Therefore, when the input of the personal identification number is requested, the display is switched, for example, the one shown in FIG. 5 is displayed in the touch panel device, thereby enabling the code input operation. In this way, the same effect as the embodiment of the present invention described above can be expected. Such a change can be realized relatively easily by changing the software for controlling the display on the ATM.

In the above-described embodiment, the display input unit 2 has been described assuming a display device such as a touch panel that can input a sign and touch it with a finger. However, the present invention is not limited to this. The structure in the display input part 2 should just be that the operator can recognize a code | symbol visually and can input this with a finger | toe. Therefore, for example, a plurality of push-type buttons having a diameter of about 5 mm to 10 mm may be arranged, and a sign may be imprinted on the head, thereby pushing the code. Even in such a form, if a finger rest similar to that described above is arranged, an input operation can be performed while suppressing peeping. Therefore, the present invention also includes a form in which the display input unit 2 is formed by push.
Furthermore, in the above-described embodiment, the configuration in which the sensor 3a is provided in the finger placement unit 3 to electrically detect the finger is shown, but the present invention is not limited thereto. For example, the finger placement unit 3 is a simple finger placement mark formed by printing, and an extremely simple configuration with an operation guidance message that recommends that the finger placement mark be placed after placing the finger on the finger placement mark. It is good. That is, instead of electrically linking the finger placement unit and the display input unit 2, it is possible to prompt the user to perform an input operation while simply placing the finger. Such a configuration can be implemented very easily. And even if it is such a form, peeping can be suppressed similarly to having mentioned above. Therefore, this form is also included in the present invention.
